INTERNATIONAL BUSINESS TIMES uk. The CF-Auto-Root package works only on the Samsung Galaxy S3 GT-I9300. It was in June 2012 that I wrote an article on the best ROMs for the Galaxy S3. It has been a long time since then and though I updated that post every now and then with the newest ROMs, I began to feel that it was better to make a new post rather than updating the old one. The Galaxy S3 is an immensely popular Android phone and it is by far the most-selling phone from Samsung and therefore it has been a darling among Android developers. This has resulted in hundreds of custom ROMs and mods, so much that it might confuse a person who is planning to switch to a good ROM on his Galaxy S3. As for myself, I have to flash a custom ROM frequently but I always prefer a custom ROM that keeps me near to the stock Jelly Bean firmware of my Galaxy S3 (with all its bloatware) but gives me a better battery-life, smoother user UI and a few other tweaks and mods. Quite recently, o example, I had been using the ParanoidAndroid ROM and I must admit it was a very lovely experience for a week. But amid all pleasures, I was badly missing the stock file manager, video player, and camera. People’s preferences, however, differ and your opinion might be a bit or fully different from me. As I said the variety and majority of custom ROMs for the Galaxy S3 leads us to a state where we are often stuck to confusion as to what ROM would be good enough to go with. The definition of good is again determined by the factor of what you like. I have been testing a bunch of ROMs for more than two weeks and found a few of them worth giving a try. Disclaimer: We would like to clarify we are not the developers of any of the ROMs listed here. The credit goes to the respective developers for working hard for us. You must know that flashing a custom ROM is a risky thing and if you are not careful enough, it might brick your costly phone. Do not proceed unless you are not sure of what it is all about. The ROMs listed below are in no particular order, so it should not be taken as a countdown. The reviews and selection are based on the author’s experience and it may be that you have a different view. We have listed what we think is one of the best. What is really best is up to you to decide. Before you really flash a custom ROM, get familiar with the things to do before and after flashing a custom ROM Root Your Phone: Most of you viewing this article, I believe, will have rooted their phone and installed CWM Recovery already. But if you have not yet a rooted Galaxy S3, please root it now: Galaxy S3 Rooting Tutorial. How to Install Custom ROMs on Galaxy S3: Download the preferred ROM and Google Apps (if applicable) from below and follow the instruction below carefully. But as I said above, your phone must be rooted and CWM Recovery installed on it. Download the ROM and Google Apps (if applicable) files. Not that both files come in zip with md5 checksums so do not extract them and copy to your phone’s internal or external (preferable) by connecting it to the computer using a USB cable. Go to Settings> Developer Options and turn on USB Debugging Mode. Make sure your phone has a good battery level, if not charge it now. Also backup and sync your contacts, messages, apps, etc. Use these Android backup apps to backup data easily. Turn off your phone and reboot your phone into ClockworkMod Recovery mode. If you do not know how to do it, here it is: press and hold the Volume Up+Home (center) keys simultaneously and then hold the Power key. Keep the three buttons pressed till the screen turns up, the Samsung logo blinks for two times. Release the power key now but keep the other two keys pressed till you see a list of options in blue text on black background with Android bot. In the Recovery the touch mode does not work, so you will have to use the Volume up and down keys to scroll and highlight and the Power button to select an option. If you have installed CWM Touch Recovery. you can operate it by touch input. The first and most important thing is to backup your current ROM. Scroll down to “backup and restore” option and select “backup”. It might take a few minutes for the backup to complete and it is a kind of assurance that your phone will be safe in case anything wrong happens. When it is done select go back option and choose “wipe data/factory reset” option and wipe it. Then go to “wipe cache partition” and wipe it. Finally, go to “mounts and storage” option and format data, cache and system. Return back to the main menu and select “install zip from sd card> choose zip from sd card” and select the ROM file that you copied to your phone in Step 1. When the ROM is installed, go back and install the Google Apps zip package the same way you installed the ROM in Step 10. Finally, go back to the main menu in Recovery and select “reboot system now”. Remember that the first boot after installing a new ROM takes much longer time than a usual boot. Sometimes it takes up to 10 minutes (maximum), so be patient. In case you phone does not boot properly and you are stuck on bootanimation even after 10 minutes, long press the power key. If it does not work for you, remove the back cover, pull out the battery, wait for a minute, reinsert the battery and try again. If you wish, you can go back to your previous ROM any time if you have made a back up as told in Step 6. Phone Stuck at Samsung Logo? In case your device is stuck on bootloop- that is, it does not boot normally, pull out the battery, boot your Galaxy S3 in CWM recovery, “wipe data/factory reset” and “wipe cache partition” and then reboot the device. You can also try reinstalling the ROM. Read our detailed guide on fixing Bootloop. 1. Android Revolution HD Developer: MIKE1986 ROM Review: I have been following mike1986 for quite a long time and let me tell you that this guy has multifarious talent. I have used the Android Revolution HD ROM on most my devices including Galaxy S3, Note 2, Note and now HTC One too and each time I could not help captivated by the performance I got on all these devices. As you can see in the screenshots, Android Revolution HD is a stock TouchWiz based custom ROM that takes away the terrible things like bloats and lag-delays from the stock TouchWiz UX and adds a number of modifications, not in the look, but it the system properties to make your device perform faster and with better stability. The ROM features CPU governors performance improvements and disabled kernel debugging for better performance, and RAM and speed optimizations. All such professional touches naturally promise a far better battery life. Downloads: Download Latest Android Revolution HD ROM Installation Guide: At the beginning of the post. 2. ParanoidAndroid ROM 3+ (now with Halo) Developer: gokussjx -PA Team ROM Review: The ParanoidAndroid ROM is one of the most popular custom ROMs for the Galaxy S3 but for almost all Android phones. Its hybrid look and feel, smooth and fast performance and decent battery backup, all make it a hotspot for those who love custom ROMs. I spent the whole last week with the latest version of the ParanoidAndroid 3 and it was a whole new experience due to its flexibility, capability of customization and, most of all, the extended desktop mode with that beautiful Pie thing (see the screenshot above). The PA ROM now comes with another innovative feature called Halo Notifications. Below is a video overview: I have written a detailed ParnoidAndroid ROM review that reveals all the aspect of this new avatar of the ParanoidAndroid ROM. It is based on AOSP and also supports themes made for CyanogenMod ROM is almost bugless but the PA Team will have to focus on improving the battery performance a little. If you want to have a fresh new experience with beautiful looks, the PA3 ROM is just for you. 3. UltimaROM Developer: Kryten2k35 ROM Review: While most ROM developers are prone to strip their ROMs to achieve speed, smoothness, and cleanliness, there are still few who prefer to be more and more inclusive. UltimaROM is one such ROM that attempts at being the ultimate choice for those whose hearts beat for the features of stock firmware and the look of AOSP. So, what are the things that this giant ROM has, making is so heavy? It is a fully loaded ROM with 5 different kernels, all Samsung Apps/Bloats, stock TouchWiz launcher, crDroid TouchWiz 4 x 5 launcher, Motorola Atrix HD launcher, Xperia Z, Nova, and Apex launchers and many others. Besides, the crDroid ROM also features 128 CSC’s (country/region codes), transparent widgets (such as AccuWeather, Fm Radio, Music Player), Multi-window with editable apps, Ink-effect lockscreen from Note 2, three pre-installed themes and option to choose from a host of other customization options. The best things is you can choose what, and what not to install. While installing the ROM via CWM, choose “Custom Installation” in Aroma installer. Among the major features UltimaROM offers, including the following: AOSP Themed Choice of Kernels in AROMA Option to remove bloat apps Nexus 4 launcher Galaxy Note II Keyboard Galaxy Note II Camera (Jobnik) Call Recording option Long Press Volume to change tracks MegaBassBeats Audio option Inverted Play Store, YouTube, Gmail, Calendar, Dropbox, etc. Tweaks to reduce lag. AOSP Lockscreen Toggle Advanced System Bar Clock Options Extended power menu Custom Boot Animations Internal2External SD Script option Transparent Accuweather Widget with Blue Date As for the battery life, with the UltimaROM for the Galaxy S3, it was good and lasted a whole day with average use. The ROM is based on stock Android Jelly Bean firmware for the phone and feels smoother and faster than the original, thanks to the tweaks done by the developer! I have not seen any custom ROM with so many options in Aroma. I really like my Galaxy S3 with all stock options with AOSP style TouchWiz and amazing performance. Before installing the ROM, make sure your phone has either CWM 6 or TWRP recovery on it. 4. FoxHound ROM Galaxy S3 Developer: raffaele88 ROM Review: The FoxHound ROM might prove an ultimate choice for you if you like a full-featured ROM with lots of settings options for customization. The ROM is more than 900MB in size and it is due to its inclusiveness. I have been using it for 4 days now and it has impressed me with its speed, smoothness, and stability. Since it is installed through the Aroma installer, you are more in control of things. You can decide what is good for you and installed the desired elements. You can choose from various custom recoveries like CWM, Siyah and Chainfire’s recovery. Moreover, you can choose a suitable Kernel (I prefer Siyah). Then there are options for stock SGS3 and themed launchers like Nova, Apex, Nexus 4, etc. and the selection interface for apps you want to install. The ROM features various performance tweaks and graphical changes and has a far better battery life compared to most ROMs. The best thing this ROM offers are found under device settings. Just explore the extensive settings and you will realize why I am talking about the FoxHound ROM in so hyped terms. The ROM also has OTA update feature and it notifies you whenever a new update is available. 5. Carbon ROM ROM Review: I came to know about the Carbon ROM a few weeks ago but did not consider it for 2 reasons then- first, I thought it was like any common AOSP based ROM and second, it was in an early stage with bugs and had issues. At the backend, however, I kept testing it. I would like to share one thing about this ROM. What I supposed was a commonplace ROM like any other, turned out to be a dark horse. I was surprised to see the potential and options for customization offered by the Carbon ROM. A few days back I reviewed this ROM and I am sure that if you want an AOSP ROM for your Galaxy S3, this is an ultimate choice. Download the ROM and read the full Carbon ROM review here. For good performance and stability, install the latest version from the “release” folder and to enjoy the latest features, go with “nightly” version. 6. Omega ROM Developer: Indie (Donate) ROM Review: The name of the 6th and last ROM in our list of some of the best ROMs for the Galaxy S3 GT-I9300 coincides deeply with the very meaning of “Omega” that is the 24th (2+4= 6th ROM) and last letter of the Greek alphabet and means “great”. It is a great ROM indeed. The developer has optimized the stock Samsung ROM to perform fast and with great stability while taking away all unnecessary bloats and yet maintaining the true soul of the TouchWiz UX as we know it. No theming, no extra bloats in the name of tweaking and performance boosting! If you want to use your Galaxy S3 with all those features you spent money for even better stability, speed and battery life, Omega is just your final destination. Another good thing about the ROM is that most mods for the device work superbly. Transparent AccuWeather widget, editable multi-window, ink effect, wallpaper scrolling are just some additional feature you can enjoy with Omega ROM installed on it. The ROM is based on the latest Android firmware for the Galaxy S3. Besides, there is another version of the ROM that lets you enjoy the optimized version of the leaked Android JB firmware. The hunt for the best still continues

Install LineageOS on i9300 Basic requirements Make sure your computer has adb. Setup instructions can be found here. Enable USB debugging on your device. Preparing for installation Samsung devices come with a unique boot mode called “Download mode”, which is very similar to “Fastboot mode” on some devices with unlocked bootloaders. Heimdall is a cross-platform, open-source tool for interfacing with Download mode on Samsung devices. The preferred method of installing a custom recovery is through Download Mode – rooting the stock firmware is neither necessary nor required. Download and install the appropriate version of the Heimdall suite for your machine’s OS Windows: Extract the Heimdall suite zip and take note of the new directory containing You can verify Heimdall is functioning by opening a Command Prompt or PowerShell in that directory and running heimdall version. If you receive an error, install the Microsoft Visual C++ 2015-2019 Redistributable Package (x86) on your computer. Linux: Extract the Heimdall suite zip and take note of the new directory containing heimdall. Now copy heimdall into a directory in $PATH, a common one on most distros will be /usr/local/bin. For example cp heimdall /usr/local/bin. You can verify Heimdall is functioning by opening a Terminal and running heimdall version. macOS: Mount the Heimdall suite DMG. Now drag heimdall down into the /usr/local/bin symlink provided in the DMG. You can verify Heimdall is functioning by opening a Terminal and running heimdall version. Power off the device, and boot it into download mode: With the device powered off, hold Home + Volume Down + Power. Now, click the button that the on screen instructions correlate to “Continue”, and insert the USB cable into the device. For Windows user only: install the necessary drivers. A more complete set of instructions can be found in the Zadig user guide. If nothing relevant appears, try uninstalling any Samsung related Windows software, like Samsung Windows drivers and/or Samsung Kies. Run found in your extracted Heimdall directory. Choose Options » List all devices from the menu. Select Samsung USB Composite Device or MSM8x60 or Gadget Serial or Device Name from the drop down menu. Click Replace Driver, then selecting Install Driver from the drop down list built into the button. If you are prompted with a warning that the installer is unable to verify the publisher of the driver, select Install this driver anyway. You may receive two more prompts about security. Select the options that accept the warnings and allow you to carry on. On your machine, open a Command Prompt or PowerShell (Windows) window, or Terminal (Linux or macOS) window, and type: If the device reboots that indicates that Heimdall is installed and working properly. If it does not, please refollow these instructions to verify steps weren’t missed, try a different USB cable, and a different USB port. Installing a custom recovery using heimdall Download a custom recovery – you can download one here. Power off the device, and boot it into download mode: With the device powered off, hold Home + Volume Down + Power.

On your machine, open a Command Prompt or PowerShell (Windows) window, or Terminal (Linux or macOS) window, and type: heimdall flash --RECOVERY .img --no-reboot A blue transfer bar will appear on the device showing the recovery image being flashed. Unplug the USB cable from your device. Manually reboot into recovery, this may require pulling the device’s battery out and putting it back in, or if you have a non-removable battery, press the Volume Down + Power buttons for 8~10 seconds until the screen turns black & release the buttons immediately when it does, then boot to recovery: With the device powered off, hold Home + Volume Up + Power.

Build for i9300 Introduction These instructions will hopefully assist you to start with a stock Samsung Galaxy S III (International), unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for LineageOS (based on Google’s Android operating system) for your device. Using these, you can build both a LineageOS installation zip and a LineageOS Recovery image and install them on your device. It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the extremely uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head. Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :). And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code and install it to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you. What you’ll need A Samsung Galaxy S III (International). A relatively recent 64-bit computer (Linux, macOS, or Windows) with a reasonable amount of RAM and about 200 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take. Aim for 16 GB RAM or more, enabling ZRAM can be helpful. Using SSDs results in considerably faster build times than traditional hard drives. A USB cable compatible with the Samsung Galaxy S III (International). A decent internet connection and reliable electricity. 🙂 Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd, which stands for “change directory”, the concept of directory hierarchies, and that in Linux they are separated by /, etc. Let’s begin! Build LineageOS and LineageOS Recovery Install the platform-tools If you haven’t previously installed adb and fastboot, you can download them from Google. Extract it running: unzip -d ~ Now you have to add adb and fastboot to your PATH. Open ~/.profile and add the following: # add Android SDK platform tools to path if [ -d "$HOME/platform-tools" ] ; then PATH="$HOME/platform-tools:$PATH" fi Then, run source ~/.profile to update your environment. Install the build packages Several packages are needed to build LineageOS. You can install these using your distribution’s package manager. To build LineageOS, you’ll need: bc bison build-essential ccache curl flex g++-multilib gcc-multilib git gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev liblz4-tool libncurses5 libncurses5-dev libssl-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc zip zlib1g-dev For Ubuntu versions older than (focal), install also: While for Ubuntu versions older than (xenial), install: Java Different versions of LineageOS require different JDK (Java Development Kit) versions. LineageOS OpenJDK (included by default) LineageOS OpenJDK (install openjdk-8-jdk) LineageOS OpenJDK (install openjdk-7-jdk)* * Ubuntu and newer do not have OpenJDK in the standard package repositories. See the Ask Ubuntu question “How do I install openjdk 7 on Ubuntu or higher?”. Note that the suggestion to use PPA openjdk-r is outdated (the PPA has never updated their offering of openjdk-7-jdk, so it lacks security fixes); skip that answer even if it is the most upvoted. Create the directories You’ll need to set up some directories in your build environment. To create them: mkdir -p ~/bin mkdir -p ~/android/lineage The ~/bin directory will contain the git-repo tool (commonly named “repo”) and the ~/android/lineage directory will contain the source code of LineageOS. Install the repo command Enter the following to download the repo binary and make it executable (runnable): curl > ~/bin/repo chmod a+x ~/bin/repo Put the ~/bin directory in your path of execution In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): # set PATH so it includes user's private bin if it exists if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi Then, run source ~/.profile to update your environment. Configure git Given that repo requires you to identify yourself to sync Android, run the following commands to configure your git identity: git config --global "[email protected]" git config --global "Your Name" Initialize the LineageOS source repository The following branches can be used to build for the Samsung Galaxy S III (International): Enter the following to initialize the repository: cd ~/android/lineage repo init -u -b Download the source code To start the download of the source code to your computer, type the following: The LineageOS manifests include a sensible default configuration for repo, which we strongly suggest you use ( don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. On the other hand, -c will ask repo to pull in only the current branch instead of all branches that are available on GitHub. Prepare the device-specific code After the source downloads, ensure you’re in the root of the source code (cd ~/android/lineage), then type: source build/ breakfast i9300 This will download your device’s device specific configuration and kernel. Now ensure your Galaxy S III (International) is connected to your computer via the USB cable, with ADB and root enabled, and that you are in the ~/android/lineage/device/samsung/i9300 folder. Then run the script: The blobs should be pulled into the ~/android/lineage/vendor/samsung folder. If you see “command not found” errors, adb may need to be placed in ~/bin. Turn on caching to speed up build Make use of ccache if you want to speed up subsequent builds by running: export USE_CCACHE=1 export CCACHE_EXEC=/usr/bin/ccache and adding that line to your ~/.bashrc file. Then, specify the maximum amount of disk space you want ccache to use by typing this: where 50G corresponds to 50GB of cache. This needs to be run once. Anywhere from 25GB-100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. You can also enable the optional ccache compression. While this may involve a slight performance slowdown, it increases the number of files that fit in the cache. To enable it, run: ccache -o compression=true Configure jack Jack is the currently used Java toolchain for building LineageOS and It is known to run out of memory often if not configured correctly – a simple fix is to run this command: export ANDROID_JACK_VM_ARGS=" -XX:+TieredCompilation -Xmx4G" Adding that command to your ~/.bashrc file will automatically configure Jack to allocate a sufficient amount of memory (in this case, 4GB). Start the build Time to start building! Now, type: The build should begin. Install the build Assuming the build completed without errors (it will be obvious when it finishes), type the following in the terminal window the build ran in: There you’ll find all the files that were created. The two files of more interest are: which is the LineageOS recovery image. which is the LineageOS installer package. Success! So
 what’s next? You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain
 and hopefully you’ve learned a bit on the way and had some fun too. . 323 108 242 260 57 11 362 267
