    Android Ice Cold Project

    AICP is known by everyone as the "Ice Cold Project" that started on a Desire HD years ago (2012) and since then has evolved into a mature ROM with the BEST community that you can find!!!

    Until Android Lollipop, the ROM has always been based on AOKP. Unfortunately, since AOKP stopped development (but made a comeback later), we changed our base to CM.
    With the re-brand of CM to LineageOS (LOS), we became LineageOS based with some tweaks from AOSP and then changed to be based on the "Ground Zero Open Source Project" (GZOSP) for Android Pie.
    We changed again for Android Q-R with a base of AOSP repositories and some additions from LineageOS for device-specific repositories.

    If there are any bugs we will sort them out if it concerns our codebase. This ROM isn't LineageOS supported, so there is no need to report errors/bugs to them!!

    Please note that official builds will be deleted from our servers every month due to maintenance services.
    Starting with AICP 15 we will be storing a copy of the most recent release here:


    Full Changelog link:
    (Just click the changelog button next to the download link in the list of builds available for your device)

    Google Apps:
    We recommend MindTheGapps as it has been thoroughly tested and it works well with the ROM, some other minimal (and others) GApps packages could have issues, so try using MindTheGapps if you have any issues with other GApps packages



    You tell... :p

    Before using the ROM:
    Q. Can I have an ETA for the next build?
    A. Yes, just look here to see what day your device is built on.

    Q. Does this ROM support custom kernels officially?
    A. No. You can still use them, but the discussion should go in the thread of the respective kernel. We don't offer support for bugs you might encounter while using them!

    Q. Does this ROM include GApps or do I have to flash them separately?
    A. No, we do not include prebuilt GApps, because of possible licensing issues with Google Software and because some users do not want GApps preinstalled as they want to use alternative services like MicroG or just prefer flashing a GApps "flavor" of their liking.

    Q. Does this ROM use the camera or gallery app from stock?
    A. It depends on the device. In most cases, these apps include proprietary libs/code and cannot be included in the device trees on GitHub or we risk having the ROM banned from GitHub. In this case, we might try to make them installable (separate from the ROM zip), or we might provide a version of these apps with the ROM that doesn't include any proprietary libs. It's also sometimes the case that these apps are simply not included because we didn't feel the need to do so for the device in question.

    Q. Does this ROM have Extended/Scrolling screenshot?
    A. No, extended screenshot was implemented using an app extracted and modified from manufacturer firmware/system images and is proprietary as well. It led to the closing of many ROM's sources on GitHub.

    Q. Does this ROM have FaceUnlock?
    A. No, FaceUnlock was also an app extracted and modified from some manufacturers. Even Google removed the Trusted Face (FaceUnlock) feature for security reasons on Android 9.0/10.x. Adding the modified feature did the same to ROM sources as described above.

    Q. Can you add (insert favorite weather provider)?
    A. No, we cannot add more weather providers as the implementations change and we (the ROM) now have to pay for most services, and that is not cheap, so we decided to use the best free service that we could find, the only way to add your own is for users to apply for their own API key to use their preferred service.

    Q. Does this ROM have private official builds with the above proprietary libs included?
    A. No, we believe in open source software, this way users know what's in the build and can replicate it themselves, all official builds are built on our build servers using the public sources from GitHub, and no one can (or would) add their own private sources to the build.

    Flashing the ROM:
    Q. What do I need to know before flashing?
    A. Check the flashing instructions...

    Q. Can the builds be dirty flashed over each other?
    A. Yes, this is how users can/should install updates most of the time, this can be done with the built-in updater service or with a custom recovery.

    Q. How do I 'dirty flash' builds?
    A 1. For "A only" devices: Wipe the System, Cache, and ART/Dalvik cache. Flash the ROM, GApps (only needed if you wipe the system), your preferred root solution, and reboot. Or just use the OTA app to perform that task for you.

    A 2. For "A/B" devices": Wipe the ART/Dalvik cache. Flash the ROM, reboot to the recovery, flash GApps, your preferred root solution, and reboot. Or just use the OTA app to perform that task for you.

    Q. How do I flash kernel builds?
    A1. If it's a .img file, boot into TWRP and go to the install page in TWRP, in the bottom right corner select "install image", select the desired kernel, then select "boot" as the destination, then swipe to flash, then go back to the install screen and install your root method again, if you don't want to lose root and reboot.
    A2. If it's a flashable ZIP, you can flash it together with a ROM update or separately. Go to the install page in TWRP, choose the kernel zip (or add it to the flash queue right after the ROM zip). Then add your root method to the queue if you don't want to lose root. Now swipe to flash and reboot afterward.

    Using the ROM:

    Q. Do I need to provide a logcat if I'm reporting a bug?
    A. If you want it to be fixed faster (or at all) then yes, you should definitely provide a logcat AND the model name. (Note: Please just link the logcat from your GDrive, Dropbox, etc. Do not post the content here. Thanks.)

    Q. How do I get a logcat, what type should I get, and more questions that can conveniently be answered by my pre-determined answer?
    A1. Read this thoroughly. Also, here's a good app for getting logs: (Root needed).
    A2. If you are already rooted, you can use the built-in feature to make a logcat and provide that. Just look into the others section on the AICP Extras main page.


    The ROM should contain everything you need to enjoy Android R. You don't need to install any Add-ons, simply download the latest ROM and GApps, then follow the flashing instructions and go!
    If you want the device to run the ROM "rooted", you can flash a root solution of your choice after the ROM zip file.

    It is STRONGLY recommended to fully wipe your device before flashing and please avoid restoring system apps and system data with Titanium Backup (or with any backup/restore app) as this can cause stability issues that are very hard to debug, restoring regular apps is fine though.
    If you believe you know what you're doing - then fine, go ahead, but please don't complain if you experience any strange behavior.

    How to flash for the first time:
    (Again: Don't do it if you don't know!)

    1. Download the ROM and GApps and transfer them to your device.
    2. Boot to recovery (TWRP is recommended, the lineage recovery is a great alternative however, it will not decrypt the internal storage so you will have to flash the rom with adb sideload or usb OTG or with an external sdcard).
    3. Wipe the System (DO NOT WIPE THE SYSTEM ON A/B DEVICES!), Cache, and Data (you might need to format the data partition!).
    4. Flash the ROM zip file (reboot to recovery before flashing anything else if you have an "A/B" device).
    5. Flash the GApps (optional, needed for e.g. Google Playstore to work)
    6. Reboot and set up your device.
    7. You can then reboot to recovery and flash the root solution of your choice if you want to, and then boot back to the system.
    The procedure may vary from device to device and is a bit different on system updates!

    The ROM has GApps persistence in between dirty flashes, so you only have to flash them once! This might differ on A/B Devices.

    Currently supported Root Solution:

    Magisk stable
    Magisk versions >= 20.4 don't usually need to be flashed on every dirty flash.
    Depending on the device, you may need to flash it every time, unless your maintainer says otherwise, you should be fine.

    Instructions for OTA ("Over-The-Air" Updates) on "A only" devices (not A/B):
    TWRP recovery is needed to be able to flash using the built-in OTA app.
    Please make sure that you are on the latest TWRP recovery, keep in mind that this could also be an unofficial version!
    On encrypted devices, you will have to enter your PIN/password in TWRP before the process starts.
    Open the updater app, download the update, then press install, press reboot when prompted, you will be taken to TWRP, there isn't any need to flash GApps separately

    Instructions for OTA ("Over-The-Air" Updates) on "A/B" devices:
    Open the updater app, download the update, then press install and wait for the process to finish (feel free to let it run in the background), then press reboot when prompted, there isn't any need to flash GApps separately

    Cool we have A12, if anyone tried it? Any bags?
    Probably i'm the only one for now 😂 Running 12 for the last couple of days on my daily driver. Some AICP Extras stuff like QS tile animation not available yet. You might observe minor visual misbehavior on statusbar, restart SystemUI then. Except that i didn't notice any bugs so far.
    Hello, do you plan to update ROM up to Android 12?
    Yes, official 12.1 releases coming soon.
    Why are there weekly updates?
    Can I make the back button on the right?
    Updating hosts for integrated adblock and security patches on 11.

    Yes, check AICP Extras -> Onscreen navigation options -> Invert layout
    Hey Sil, quick question. Does your rom include the option to add the cursor arrows to the navigation bar?
    Okay never mind. My P5a came in today and somehow I was able to load the ROM without any issues ON MY FIRST TRY. Wow talk about luck on my part... haha.

    Anyway, I found the cursor arrows for the navigation drawer...but I found a problem. Or, at least I think it is a bug? When you invert the back and resents button it inverts the arrows as well. Is this intentional? If so... by chance do you think the option to not invert the cursor arrows is possible?
    Other than that I love the ROM so far. Tomorrow will be the first test run of the phone and the ROM!
