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 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!!
Code:
#include <std_disclaimer.h>
/*
* Your warranty is now void.
*
* We are not responsible for bricked devices, dead SD cards,
* 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.

You tell...
FAQ:
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 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. Can the builds be dirty flashed over each other?
A. Yes, this is the usual behaviour on flashing a new official build by (or using) the build-in updater service.
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 AND the model name. (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 Q. 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 Zipfile.
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 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), GApps are already included for some a/b devices.
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 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 AvB Devices.
Currently supported Root Solution:
Magisk stable
Magisk versions >= 20.3 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.
PREREQUISITE FOR OTA ("Over-The-Air" Updates):
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.

FAQ
1) When official?
I haven't decided if I want to go official or not.
2) Will there be regular updates?
Atleast once/month, usually after aosp security patch is merged.
Apart from that, Ill release a new build in case of major bugs that breaks the ROM to be used as daily driver.
3) Reporting bugs
DO NOT Report bugs if
• if you didn't perform a clean install.
• if you're running a custom kernel.
• if you've installed Xposed.
• if you're using battery/thermal mods.
4) How to report bugs?
• Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues.
• Mention what custom stuffs you've installed in the rom, like Magisk modules, etc.
• If the problem disappears after disabling selinux, disable SELinux and grab logs using SysLog app.
• If its a random reboot, grab dmesg. [Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless.]
5) Disabling SELinux
Needs root. You can disable SELinux via the following options.
• SELinux Mode Inverter Magisk module
• SELinuxModeChanger App
• Terminal Emulator App
To disable SELinux using a terminal emulator, run the following commands
Code:
> su
> setenforce 0
6) Taking Logs
Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.
• Using adb
• Using MatLog app
• Using SysLog app for audit logs

I'm not sure if that could be the issue.
But flashing firmware zip won't cause any issue even if you're flashing firmware after flashing ROM. You may try flashing the correct firmware as they're are global & Chinese firmware. Thanks.

Read the whole OP! Be respectful to each other and don't ask for ETAs, it's considered as being rude!
Syberia Project (aka Syberia OS) is a custom ROM for Xiaomi MI A3 that implements various features. This project was designed by our "Syberia Team" from scratch based on AOSP source code with some CAF fixes and improvements. Our team: @DennySPB, @blinoff82, @alexxxdev. Also many thanks to our designers @rlshukhov and @a18h for logos, wallpapers and bootanimations.

This is fantastic!
But no matter what I do I can't install even core gapps. I flash them via adb sideload, perform a factory reset and nothing.. I feel like I've tried everything. There's no problem with Magisk tho. Can you please include some gapps in the rom?

Amazing news! Official ROM and latest Android version!
Hopefully the permissive SELinux can be sorted out with enough logs, but still, very nice work so far.

Does anyone can help me about the recovery via fastboot installation? I mean is there need to change slot e.t.c... And after recoverie's flashing, how we reboot to recovery, via a simple fastboot command?Thanks.

Yeah, a12 not so fast at gapps bringup, we have limited chose to BitGapps, Nikgapps or FlameGapps, and Nikgapps with FlameGapps have some issues while flashing it on some devices (already reported to the dev), and only BitGapps works fine, but there are only Minimal package.
However i created a modified Nikgapps(stock) package - download

Generally speaking, IMHO doesn't matter how you got into recovery be it by command or power+vol+

And the slots? Is there any need to change them during flashing?

papafan said:

Click to expand...
Click to collapse
When you flash something over fastboot you are to manage slots. When you do by recovery it manages slots. So up to flashing the recovery you'll manage slots. Afterwards flashes are done by recovery. Since recovery changes slots when you flash rom or update. Both slots should have the same firmware level (e.g. android 11 firmware.) If you have incompatible firmware on other slot it may cause problems on next update or full flash. IMHO op should explain a bit more about slot management. The same process is known to cause unwanted problems before. You can check the lineageos 18.1 oss thread for it.

Hi,
Is it possible to safely install this ROM from android 10 stock EU version? (or, must I already be under A11 and in this case what should I do?)
I'm still stuck on A10 and the September 2020 security patch on my French version of the Mi A3
Sorry I'm a beginner

I think you must first update to a11. Do factory reset on your a10 first.

Problem is that I still do not have the possibility to do OTA to A11...
In France we are literally blocked on A10 and the September 2020 security patch...

Then you can flash it with mi flash.

I don't understand what to do in order not to lose my data, I would just like to update.
If I want to install the update without fear I have to make a backup. OK
To make a full backup I need TWRP. OK
To install TWRP to be able to make my backup and not lose any data I have to root my device with magisk. OK
If I root my device with magisk it makes me wipe all my data...

If I were you I wouldn't rely on twrp for backup. Because once you update to A11 you ll have problem with twrp hence restoring it. On the other hand even if you are able to restore it somehow, probably you would end up with a bootloop anyway. Because when android version changes, data partition backup of other versions won't be compatible with newer one. I suggest you to have per app backup within os.

New update is out!

New update is out!

everything working fine, new icons and animations for udfps are pretty good and now it recognizes really fast. one thing i noticed is that the screen flicks when unlocking with figngerprint but just a little bit, its not something that really bothers as before. updating was fine without even needing to make a backup. anyways ty for, basically, the best rom for mi a3, if it wasnt that, i think we all would have already changed it. keep up the good work!

I just did the installation and the rom is fantastic!
Leaving Miui..
Everything seems to work very well.
Congratulations to those involved!!

Notes
• Build type: User
• Encryption not supported, Decrypted by default
• Selinux is Enforcing
• FMRadio Included
• Do not flash recovery.img available on the spark download website
Flashing Instructions:
Clean flash (Coming from a different ROM):
• Download ROM
• Download Custom Google Apps Package (Like Nikgapps core/basic or Mindthegapps) if the ROM is Vanilla variant (On GApps ROM variant Google Apps are included, don't flash a separate Custom Google Apps package)
• Reboot to Recovery.
• Wipe System, Data, Vendor, Cache, Dalvik/ART cache partitions
• Flash latest stable firmware v11.0.3.0 before flashing ROM
• Flash ROM zip
• Flash Custom Google Apps Package if the ROM is Vanilla variant
• Reboot to system
To get root access, Reboot to recovery after ROM setup and flash Magisk.zip
BOOTLOOP SITUATION: If you are coming from stock/custom MIUI or any ROM which had data ENCRYPTION, you will face bootloop and can not boot into the system. In such case you need to FORMAT data after flashing the ROM. Otherwise the ROM won't boot (Read detailed instructions from here)
Dirty flash (Updating to a newer build):
• Download the new update ROM zip
• Reboot to recovery
• Do not wipe anything
• Flash the new update ROM zip
• Flash the same Custom Google Apps Package again you flashed before (For vanilla users)
• Flash Magisk again if you are rooted before (For rooted users)
• Wipe Cache and Dalvik/ART cache
• Reboot to system
Important note regarding SparkOS 13.6 update
This is a huge rebase of the ROM's source code after the March update, So Clean flash is MANDATORY for all users. Some bugs from previous versions have been fixed in this version and some new features can be noticed. Some customizations have been temporarily removed (eg: Smart charging, QS row & column customisation etc) and will be added in future releases (Read official community post).
You should be aware of some known source bugs in this release before updating to 13.6. These bugs are not device specific and are present in all Spark official devices which will be fixed in the next update.
Known bugs are;
1. Launcher settings are crashing with light theme (works fine with dark theme). You can use a different Launcher but I think Pixel launcher Extended will not work anymore as spark is now completely based on lineage
2. Shortcut buttons glitches in recent panel.
3. Visual glitch on Quicksettings/Statusbar after a reboot (Restarting SystemUI fixes it for now)

This is great. Seems to run well - but can't get it to play nice with Viper4Android.

No issues with viper4Android here.
Check if you've rooted properly?
Or maybe you are using a mod version of viper4Android.

Been using it for half a year and it's the best Android 13 rom I tried (not that there's many that are up to date)

I used the repackaged v4a from github. Clearly something went wrong here if it's working at your end. I'll try again later when I'm home as I'll need to install from scratch having reverted to A12. Guessing maybe I just needed to reboot again or something. Here's the version I used:
GitHub - programminghoch10/ViPER4AndroidRepackaged: A refined ViPER4Android installer.
A refined ViPER4Android installer. Contribute to programminghoch10/ViPER4AndroidRepackaged development by creating an account on GitHub.
github.com
I have to say the smooth responsiveness on these new A12/A13 ROM builds is surprising given how often A11 would lock up for me. Maybe my device just finally needed a reset idk.

OK. Mystery solved. Turns out that Viper4Android does indeed work - it just needed an extra reboot.
So I flash it > reboot > v4a App appears on next boot but doesn't work > reboot again > v4a works.
Weird but makes sense. Sorry for the confusion.

I couldn't receive this kind of google login authorization on this rom "is it you trying to sign in". Device wasn't appearing in google account double verification. No problem in a13 elixir.
Also sadly no option 2g connectivity.
Rom itself seems smooth. ATM moved back to A10

I have problem, the screen show on/ off at redmi boot logo

CPU cores seam to be locked to 1400 mhz

Hello İ installed latest Spark OS gapps build on my a205f i loved the rom but it has a bug phone screen freezes cant close the screen no reaction to calls,notifications,holding down the power button the only solution is to wait for the battery drain it happened 2 times what can i do i guees this build is laggy

This is possibly a long shot but any chance of modified files for higher quality audio on Bluetooth SBC (or AAC)? It used to be you could patch it in via Magisk but the module no longer works on newer android versions and if I'm correct the edits need to be made before a ROM is built. If you're able to, any chance of some experimental files for me to try out?
I think the values are in a2dp_sbc_encoder for SBC, a2dp_aac for AAC. A2DP_XXX_DEFAULT_BITRATE 000 where XXX is SBC or AAC and 000 is the bitrate in kbit/s.

Latest Vince just got released yesterday - thank you

Hi,
I installed this rom, until I see it I'm liking it, but the screen rotation doesn't work.
Any idea?
Thanks...

Hello everyone, just flashed this ROM on my Vince (coming from Elixir 3.3 - A13).
Since I use this phone to debug my apps, I need to connect Chrome DevTools to it.
What I've done so far:
- wiped everything
- installed Spark-13.3-Official-vince-20230105-gapps
- installed Magisk 25.2
- registered my Google account
- updated all apps (through Play Store)
- enabled Developer options, then USB debugging
Now, when I launch Chrome DevTools on PC, I can see the phone but the webpages list is empty; it also doesn't show any WebView instance (see the screenshot below).
Remote debug was working with Elixir 3.3 on the same phone and PC, so I suppose the difference is in some ROM setting... something to be changed here, but I'm out of ideas...
Does anyone have any suggestions about this?

First, make sure you have enabled auto rotate screen option. It is disabled by default.
If it's enabled send a screenshot from sensor test app (available in playstore). ROM doesn't have issues auto rotates screen.

LineageOS is a free, community built, aftermarket firmware distribution of Android 12L (Sv2), which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS Githup repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.
Installation:
If you are on stock OS, you need a custom recovery first. You can get the recommended LineageOS recovery in the official installation instructions link below.
You can use TWRP for installation, however it is no longer officially supported since we do not have full control of its update cycle and potential issues.
If you are coming from stock or other ROMs, you need to make a factory reset.
As always, make sure to backup before installing this ROM.
Installation Instructions:
Backup your data and see the next post below

Special thanks to @Astridxx for the device tree sources and for helping me out and to @en666 for early testing the initial build
Important Notes:
As you can see from my profile, I'm not an experienced developer. I've made some builds as a considerable amount of users showed interest in having their devices updated with latest LineageOS code. Therefore, my main objective here is to bring the latest Android security patches to kuntao making monthly builds.
To be clear, I'm more in a situation of "user became builder" than of "ROM developer". Please, understand this.
Long live to our beloved kuntao!

Thank you so much for keepng Lineage alive, its very much appreciated.

@leo_97 thank you for this new build! Installed it straight away and now the phone is running since then and also, I've flashed with battery at 67% and atm, after a quite hard usage to test out the new features, I'm on 13%. Basically, so far so good!
p2a42, twrp 3.7, rooted, unencrypted

Thank you @leo_97 !
I was frustrated that Lineageos 18.1 was no longer maintained when I saw this update!
It's amazing
To all users and developers who tested and created this ROM, is it time to switch on this version ?
Or is it better to wait ?
For example, automatic update is possible after install ?

You are welcome
If it's time to switch, I believe it's a matter of personal decision. Maybe you could wait the next build and then decide...
If with "automatic updates" you mean OTA updates, then the answer (as already pointed out by @utwer ) is no. But once the trees are stable enough, I hope every user will be able to just update to the newer versions flashing ROM ZIP through TWRP (just like it's done on LOS18.1)
BTW, IDK if you already saw it, but we are maintaining a monthly build of LOS18.1 which you can download from here. The source tree used there is far more tested (as it's older) than this one. Anyway, except by the encryption thing, you shouldn't have any problems using this LOS19.1 ROM as our amazing developers made an excellent job here.

Reg, Ive installed it and I may say it is quite good. Not tried to root it yet. Dont have direct problems with ROM and functionality, for me everything works. Camera, Location, GSM, Data, WiFi. With developer options I've turned off Animation scale on three options to OFF, and is good. Stable reliable.
MindTheGapps-12.1 works every app from Google, Phone, Contact, Gmail, maps...etc...
What I need root mostly is for Call recording (Skvalex) and Viper4Android.
Some words about twrp-3.7.0_9-0-kuntao.img,
With this I have only problems, so far I lost a few backups and I need to install it all over again a few times allready. Disappointed very. I can't rally on this when I make a nandroid ba.ckups.
Also lost backups for LOS18.1 and I am been very pis....ed off. Error 255 on System recovery, other Data, Boot, EFS, Vendor, etc.. recovery is good.
So I've installed OrageFox for Kuntao. Tried several backups to restore already and I may say I am very satisfied. Puh
What is on my mind, when I installed a Magisk 25.2, no matter of LOS 18.1 or 19.1 with very few modules, after 7-8 reboots I've got boot loops which is beyond repairable.. Try to remove modules in TWRP in file manager, uninstall whole magisk, no way, but what it is seems that DATA got corrupted some how, everytime.
There were also installed TWRP mentioned above.
Now I am with OrangeFox and I will try tomorrow to Root it and see is there any connection between Magisk and recovery software (OrangeFox or TWRP).
Reg

Tried quickly this ROM yesterday. In general all working, but didn't test much.
Few feedbacks:
-Scaler for brightness level is weird, very different from the original Lenovo roms. Anyway, not really important, but something that I noticed.
-Missing haptic feedback when using the fingerprint reader as a gesture button. Again, not critical, but I am really accustomed to it and thus I noticed immediately.
-Missing haptic feedback intensity regulation, or could not find it. It's there for general call/notification vibration, but if I remember correctly lineage could also change haptic.
Impressed that you could integrate also some lenovo features, even if of course not all of them
If you want me to test something more specific, please let me know. Ah, my model is the 4 GB/ 64 GB combination.
Cheers!

So for 18.1 we can just flash the newer versions via TWRP and do not have to reinstall the entire ROM?

So,
Resolved issue of bootloops:
after you install SU like Magisk, and wan to freeze apps by Titanium Backup or Neo-Backup, Apps which causes bootloops are ROM's Phone and Massages (In my case, for 16.1, 18.1, 19.1), I freeze Audio.apk who need to be shutdown for Viper4Android app who takes audio management and freezing is OK.
But Phone and Massages which are frozen cause bootloops, so you need to return from freeze state somehow in TWRP or OrangeFox with file management or revert backup. Revert backup is easier .
Camera; found issue when suddenly is out of work and cannot be connected to app. Also have problems with video cast Skype, Viber, Whatsapp, Telegram video is frozen. Hardly switch in Camera app from Camera mode to Video mode and vice-versa.
Clock & Info; missing dock icons and info, can't "capture" moment for reason when they disappear but after a while all is returned again.
P2oggle, left switch button work okey in form of 0.4 version.
Reg,
thanks on the development for this 19.1 ROM.

Hello,
I've been using this ROM as my daily driver and couldn't confirm this camera bug, could you please give a few extra details? I tested on Telegram app. Which version are you using? The Play Store's one or the one from Telegram's official website? Did you give the app "While using app" permission or "Ask every time" permission for camera? Are you sure the QS Tile "Camera access" is activated (available) when the mentioned bug occurs?
Regarding the Clock widget, yes, there's a small glitch and I'm not sure on how to fix it, if it doesn't load at all, a system reboot should fix it.
P2oggle v1.2 is 100% working as far as I can tell, so you guys can try it too if you want.

I'm not sure if it's possible to "fix" the brightness slider.
If with "haptic feedback" you mean the phone vibration, you can just adjust it to your liking in Settings > Lenovo parts > Vibration strength, it should affect fp reader too, dunno if it affects call vibration but IFAIK it should.

The Play Store's one or the one from Telegram's official website? Did you give the app "While using app" permission or "Ask every time" permission for camera? Are you sure the QS Tile "Camera access" is activated (available) when the mentioned bug occurs?

Yes on latest Telegram app from web site, tried with Google Meet, Whatsapp, Viber.., always breaking connection with API/drivers. Yes I gave all permissions to Camera. If I am not giving permissions for camera, I have always noticed to confirm what I am giving, so I am excluded from this solution. And clean storage and cashe from app regular but not prevail.
But, in a while after installed a new ROM without giving SU/Root I noticed this behavior, right after I wrote earlier post up. My bad .
Choppy startup of camera, can't easily transfer from video 2 camera and vice-versa, so I tell to my self to test intensively.
Regarding the Clock widget, yes, there's a small glitch and I'm not sure on how to fix it, if it doesn't load at all, a system reboot should fix it.

Yes after a while it is returned back without reboot. weird.
P2oggle v1.2 is 100% working as far as I can tell, so you guys can try it too if you want.

Big Thank you for this release. Will try it. - test

Great job, dude.
Previous versions had some buggy charging driver that left a wakelock running after each charging, and u had to restart phone each time or leave it to slowly drain battery by not going to sleep.
Somehow this problems seems to be gone in your build and that is awesome.
I've been using the build for about 2 weeks now and so far everything seems to be working fine.

LineageOS is a free, community built, aftermarket firmware distribution of Android 13 (T), which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS Githup repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.
Installation:
If you are on stock OS, you need a custom recovery first. You can get the recommended TWRP recovery in the installation instructions link below.
If you are coming from stock or other ROMs, you need to make a factory reset.
As always, make sure to backup before installing this ROM.
Installation Instructions:
Backup your data and see the next post below

Acknowledgements:
Thanks to all Lineage OS developers
Special thanks to @Astridxx & @XiaoAk for the device tree sources and to @Astridxx for (once again) helping me out
Important Notes:
As you can see from my profile, I'm not an experienced developer. I've made some builds as a considerable amount of users showed interest in having their devices updated with latest LineageOS code. Therefore, my main objective here is to bring the latest Android security patches to kuntao making monthly builds.
To be clear, I'm more in a situation of "user became builder" than of "ROM developer". Please, understand this.
Long live to our beloved kuntao!

Great work! Will test it when I have time, been waiting for this..

Hi all. I read these P2 forums for long time, but never participated. I love our P2 phone, riding a P2 since the release date and never changed. Now I got a message from my bank that the android version is too outdated to use their banking app, and they want me to switch to a newer OS. I could have ditched the P2, but couldn't. Therefore....easiest solution was to buy a second one xD I will test on the backup unit some of the roms available here, probably starting from the roms of @leo_97 . I need a stable daily driver, thus when I find something that works for me I will freeze it there for some time. But, in the meantime, I can help out with testing, starting from mid April onwards thus, feel free to contact me, and I will be a bit more active (and not passive) here in XDA for the coming months.
Cheers to all, and thanks @leo_97 , @Astridxx, @XiaoAk (and @mikeioannina for all the past efforts on P2!).

Hi
I just tested it on a P2 for a few hours and it works great! Thanks!
Is there any way to get full device encryption to work?
If I understand correctly, someone can access the phone's files even if you have a pin or password as it is now.

You are welcome
So, IFAIK we don't have a way to make FDE work on A13 ROMs, A13 moved to FBE (File Based Encryption) which is not supported by 3.18.x kernel and we don't have rn a patch available that could enable it on our kernel version.
Regarding data access, I believe so. Without storage encryption, booting into recovery will already give access to the files. IIRC to this date encryption is fully working only on A11-based ROMs and maybe on some A12 ones.

Okay, so I'm stuck in a boot loop. I flashed the ROM from the link above but the phone won't start up. I just get the Lineage booting screen with the circle moving right to left. I've left it for 15 minutes just in case the first boot was slow but nothing else happens. I've tried to restore my original backup which was Lineage 17.1. It seemed to work, no errors from TWRP but now i just get the Lenovo screen and then it boots to fastboot mode. I flashed Lineage 20 for a second time but the same happened. I tried a different backup from August last year, again it just boots to fastboot.
Any ideas?
Cheers, Si.
EDIT: I've just noticed that I missed out step 3, reboot to recovery between Data wipe and flash ROM.
Now it boots no problem.
Cheers, Simon.
EDIT AGAIN: I still can't revert to either of my previous backups of Lineage 17.1. I would really like to be able to do this. Can anyone suggest why it will only boot to fastboot mode after a seemingly successful restore?
Thank you,
Simon.

@simes303
Don't know what the problem is, but I'd flash stock via fastboot. Then reinstall TWRP and restore LOS.
When things go wrong it's better to start from scratch rather than tinkering around and doing temporary fixes.

how is the battry life anyone?

Hi,
How is this different from flashing stock with TWRP?
Cheers, Si.

Used briefly but battery life seems worse, its like draining. Using 12L Lineage os and its way better.

Didn't test much but its way waay noticable, you wouldn't want to use when you see the difference (didn't differ with or without gapps)
btw thx to all devs, using lineage os a12.1 and its good on battery

Battery life for me is considerably better than the Lineage 17.1 that I was using before, no question. I'd estimate almost twice the duration. I'm very happy with this ROM, thanks to all involved in developing it.
Simon.

I've actually just bought a brand new 64 Gb Lenovo P2 pretty cheap from eBay and I will definitely be flashing this Rom onto it.
Thanks again,
Simon.

Hi,
Does this ROM have USB OTG support? I can't get the phone to connect to either my external SSD drive or my bicycle helmet camera since I flashed this ROM. Both these things connected via OTG cable to my phone when I was running Lineage 17.1 and they also connect to the new P2 that I bought recently that still has stock OS. I've tried three OTG checker apps which all state that my phone is OTG compatible.
Thanks, Simon.

Hello Simon,
Yes, it does have OTG support. IFAIK it should work correctly with both FAT32 and NTFS partition types on external storage devices.
