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 with a base of AOSP repositories and some additions from LineageOS for device specific repositories.

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

* Your warranty is now void.
* We are not responsible for bricked devices, dead OTGs,
* thermonuclear war or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications and if
* you point the finger at us for messing up your device, we will laugh at you. Hard & a lot.

Feature list (rough overview)

In the beginning we would like to thank:

GZOSP team
LineageOS & CM (dead) team
@maxwen and the rest of the OmniRom team
DU team
Resurrection Remix team
AOSiP team

@LorD ClockaN
+ the rest of the crazy bunch that we call "team"

We are paying for servers that build weeklies and everything that comes with this, so EVERY DONATION will really be appreciated and be used to cover those expenses.
Thank you!!


Mega folder (stable releases) 15.0 Version

Download link: https://mega.nz/folder/gkYHyCoS#RzQt5NHN7Vpfx-vaH3dJbg

This ROM is compatible with K30 5G, K30i 5G and K30 5G Racing edition (tested by many users of all variants). Enjoy!!

Full Changelog link: https://dwnld.aicp-rom.com/

Google Apps (GApps):
(Remember to choose always ARM64 10.0 packages:)

or https://opengapps.org/

NOTE: if you also want to root your device with Magisk, ensure you are using the official releases from here https://github.com/topjohnwu/Magisk/releases otherwise you might get malware!!

- SELinux is permissive.
- Fast charging info on lockscreen (but charges quickly!).

Before using the ROM:

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. Information about Xposed, EdXposed or Riru Core can be obtained from the XPosed General forums .

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

Q. How can I 'dirty flash' builds?
A. Wipe Cache and ART/Dalvik cache. Flash the ROM, GApps, your preferred root solution and reboot.

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 AND the model name. (Note: Please just link the logcat from del.dog, gist.github, 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 Q. You don't need to install any addons, simply download the latest ROM and GApps, then follow the flashing instructions and go!

It is STRONGLY recommended to fully wipe your device before flashing from another ROM 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 (feel free to ask before bricking!! ;) )

How to flash for the first time:

1. Download the ROM and GApps package (optional) and transfer them to your device.
2. Boot to recovery (PBRP recommended).
3. Wipe Cache, and Data (you might need to format data partition!).
4. Reboot to recovery again.
5. Flash xiaomi.eu (v12.0.7.0 is strongly recommended).
6. Flash ROM.
7. Flash GApps (optional, needed for e.g. Google Playstore or Google Camera to work).
8. Flash Magisk (optional as well).
9. Format data and cache partitions again.
10. Reboot and set up your device (realize that first boot might take longer than usual).
11. Enjoy!

AICP has GApps persistence in between dirty flashes, so you only have to flash them once!

Error at step 6 : Failed to mount '/system_root' ( No such file or directory )
That happens sometimes when dynamic partitions has been updated and can't be mounted again, but you shouldn't worry about that. Just reboot to recovery and then you will be able to mount /system partition as always.
Besides, looks what says at the top of the screen: "Install zip succesfully"

- Increase number of icons in status bar (we don't have notch, so this limit is useless).
- Decrease status bar weight.

(I haven't updated prebuilt kernel as version seems to have draining issues, so I'll stay in kernel).
AICP changes: https://gerrit.aicp-rom.com/q/statu...before:%222020-10-11+17:00:00%22+branch:q10.0
Closed issues at GitHub (if any): https://github.com/Redmi-K30-5G/device_xiaomi_picasso/issues

How to upgrade:

Dirty flash should be enough (if you face weird issues/bootloop, then try a clean flash before reporting!).

Dirty flash:
1. Reboot to recovery (PBRP recommended :D )
2. Flash ROM.
3. Flash GApps (if you had).
4. Flash Magisk (optional, as always).
5. Wipe data and cache.
6. Reboot to system.

If you face any flash error and the ROM doesn't install succesfully, take recovery.log and send here.

Enough of works, hope you enjoy this new safe, snappy and cold build!!

True, I've just seen that; when I hide the navigation bar in AICP settings, the back gesture disappears and is not available (but the home and recents gestures work though...).
Nevertheless, you can go to Settings/System/Gestures/System Navigation/Full gesture navigation (or something like that, sorry I have the ROM in my native language and not in English).
Click on the settings icon on the right side of the Full gesture navigation option, and there you will be able to hide the pill and maintain the other gestures ;)

And whats about deep sleep? The ROM can enter on it?

And can hide notch completely?
Deep sleep works, but notch can't be totally hidden for now. You can only remove the black space between the frontal cameras in Display < XiaomiParts.

I've been using your ROM since the Stable update glitched touch on my Redmi K30 5G Speed Edition. The phone is my daily driver and I'm very satisfied. Thank you for your work!
