[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] hungphan2001:
AICP

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 we are now based on the "Ground Zero Open Source Project" (GZOSP) for Android Pie.

If there are any bugs, either we will sort them out or the GZOSP team, if it concerns their code base. This ROM isn't GZOSP supported, so there is no need to report errors/bugs to them!!

You tell... :P

FAQ:

Before using the ROM:

Q. Can I have an ETA for the next build?

A. Yes, just look in the OP to see if your device is built on a nightly or weekly schedule.

Q. Does this ROM support custom kernels officially?

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

Q. Why doesn't this ROM support Xposed?

A. Xposed is a hack that is geared towards AOSP. Custom ROMs modify the framework a lot, so Xposed can cause a ton of issues on custom ROMs. Now it might work for you, however it is not to be discussed in this thread, and you should refrain from posting bug reports.

Q. Alright, but I still want to flash Xposed, so which version do I need to install?

A. You will need to use the version arm64/arm/whatever for SDK 28.

Flashing the ROM:

Q. What do I need to know before flashing?

A. Check the install instructions in the first post...

Q. Can the builds be dirty flashed over each other?

A. Yes, however make a nandroid backup first as there is a chance of getting a bootloop or encountering bugs. Also bugs may only be reported on a clean flash.

Q. How do I 'dirty flash' builds?

A. 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 preform 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 loose 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 loose root. Now swipe to flash and reboot afterwards.

Using the ROM:

Q. I installed a bad theme and now I'm getting a bootloop, how do I fix it?

A. In TWRP, flash the substratum rescue zip that's in the substratum folder on the internal storage.

Q. I'm having issues with WhatsApp, how do I fix it?

A. Read this

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. (Note: Please just link the logcat from your GDrive, Dropbox, etc. and 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: https://play.google.com/store/apps/details?id=com.tortel.syslog (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 in the AICP Extras main page.

The ROM should contain everything you need to enjoy Android Pie. You don't need to install any Add-on's, simply download the latest ROM, GApps, flash it and go!

If you want the device to run the ROM "rooted", you can flash a root solution of your choice after the ROM Zipfile.

It is STRONGLY recommended to fully wipe your device before flashing and please avoid restoring system apps and system data with Titanium Backup as this can cause stability issues that are very hard to debug.

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 it!)

1. Download the ROM and GApps and transfer them to your device.

2. Boot to recovery (TWRP recommended).

3. Wipe the System, Cache, and Data (you might need to format the data partition!).

4. Flash the ROM Zipfile.

5. Flash the GApps (optional, needed for e.g. Google Playstore to work).

6. Reboot and set up your device, enable developer settings and in them OEM unlock/Advanced reboot/USB tethering.

7. Reboot back into TWRP recovery.

8. Flash the root solution of your choice (optional).

9. Reboot your device.

The procedure might 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 AvB Devices.

The root solution can be flashed together with every OTA update (= ROM Update).

Currently supported Root Solution:

Magisk stable

Magisk versions >= 17.2 don't usually require 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.

PREREQUISITE FOR OTA ("Over-The-Air" Updates):

To be able to flash using the built-in OTA app, TWRP recovery is needed.

Please be 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.
