Is there a chance that the transition from 11 to 12 android will be made by a simple update as it is now with version 11, and not a complete formatting of the device?

I really do not want to deal with the full configuration of the phone, recovering passwords and logins. Backups do not give 100% recovery.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] jjpprrrr:
Nope, because the old encryption method does not boot on android 12 with a clean install. Our phone was launched with Oreo, and currently there is no vendor officially updating such old devices to 12. A lot of changes are needed to make it work.

Incompatible changes are also made on the ROM side, like different sets of prebuilt packages and configs. The yearly android version update is the only opportunity where we can make breaking changes.

Today I moved from PE11+ to PE12 without any problems.

At first glance battery life looks better.

I noticed a problem with Gmail notifications - I'm not receiving them at all. I've tried reinstall the app, but haven't received any email so far, so have no idea whether it helped. Other apps notifications work well.

Also, I'm curious whether it's possible to remove the bottom google search bar and date that is located in the top left corner.

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] sso1955:
Download the PixelExperience Recovery. Simply download the latest recovery file.

Connect your device to your PC via USB.

On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:

adb reboot bootloader

You can also boot into fastboot mode via a key combination:

With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.

Once the device is in fastboot mode, verify your PC finds it by typing:

fastboot devices

check

TIP: If you see no permissions fastboot while on Linux or macOS, try running fastboot as root.

Flash recovery onto your device:

fastboot flash recovery <recovery_filename>.img

Use this gCAM port MGC_7.4.104_V0a

If you do not need to use 60 FPS recording, you can use latest package: MGC_8.1.101_A9_GV1x

PS: You should install com.android.mgc but it does not matter which one you select since we do not have any camera app to mask. They are all the same but only has different package name.

These are from developer named BSG and can be downloaded from here: BSG page

A few bugs that i caught:

1. Screen sometimes doesn't off (in options it on 30 seconds) (over 3 times already)

2. When i turned off the alarm in the morning it off altogether in options (1 times)

3. Freezed and rebooted by himself.

Installed by instructions, all clear...
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] jjpprrrr:
1. That usually means some apps or services kept the screen on.

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] jjpprrrr:
It will be in future versions. It's not possible from PE 12 BETA to PE 12 because PE 12 BETA didn't include a system updater. In the future, you should be able to just click install in the system updater.

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] franky88:
This is my first time, so I dont understand '

Note: The latest TWRP and OrangeFox are able to DECRYPT the /data partition on android11. However, during our testing process, formatting data to bootstrap the ENCRYPTION is still a hit or miss. Some users will get working encryption upon the initial format and boot, but others will have a broken encryption and may need another data format. /data will appear to be encrypted, the recovery will prompt you to enter password, but if you skip/cancel the password prompt, you may see that files are not actually encrypted. This does not happen to everyone using TWRP/OrangeFox, and the cause is still being investigated.

Therefore, format data with PE recovery is still required for clean flash.

If you are already on the previous PE 11 build, OTA or dirty flash is Fine. ' what does mean. Do you want to say dont use twrp or Orange fox? Only terminal use?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] jjpprrrr:
It means using PE recovery is required. You should not use TWRP or OrangeFox.

Big thanks, perfect firmware, clean flash after 11 LOS, working wonderful, even Mifare NFC Cards works (which don't work in almost all 11 firmwares i have tried) and very good calibration of auto brightness.

Also a nice trick with keymaster from perseus).

About google camera port - i recommend stable 8.1 private version from BSG, works great, even vendor video features like OIS or 1/8 slowmo. It can be found in his channel.

I have only one minor problem with fast camera opening (when power button pressed twice). From locked state it asking for phone unlock, and when unlocked - camera not opened. Android 11 firmwares can open camera even in locked state, and it seems to be problem of android 12 itself.

Happy new year to all.

I am with PE11 and following all the steps I try to install PE12. I have tried several times but I always get the message cannot read "filename.zip".

I have downloaded the file three times but I always get the same message when I type the command "adb sideload filename .zip".

I tried and reinstalled PE11 successfully without any problems (clean install).

Any idea what could be wrong?

@jjpprrrr thank you very much for keeping our mobile alive
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] t_leite:

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] sso1955:

I have renamed the file name to pe12.zip and i give the command

I don't think so...

Why a space between name and extension is needed???

As you can see in the attachment there is not space between name and extension in the original file.

Also in the PE_Plus.zip file, witch is the file for Pe11 Rom has no space and can be flashed normally without any problem.

Hello, thanks for the ROM, very nice, although got an issue on build

SQ1D.211205.016.A1

PixelExperience_polaris-12.0-20211223-0300-OFFICIAL

Steps to reproduce:

- Enable Bluetooth

- connect to car handsfree

- screen becomes black and no reaction to touch after few seconds

Only power button responds to long press so that power menu (in another dialog window for some reason) appears.

After reboot phone re-connects to hands free and same issue repeats, so I had to disable quickly Bluetooth on startup and remove the device from list.

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] jjpprrrr:
Here are a few things you can try:

- update your platform-tools

- check the md5 hash of the zip you downloaded and compare it with the one on PE's website

Can you please take logs and send it to me? If you have root, you can do it on your phone with apps like Syslog. If not, you can also enable USB debugging and connect your phone to a computer. Use command "adb logcat > bt_crash_pe12_date.log" to capture the logs. Hit "Ctrl + C" when you are done.

Note that you need to do this during or after the black screen appears. Do not do this after a reboot, as the log buffer will be cleared.

I have got some reports regarding similar issues, but I haven't received any valid logs yet. I personally do not have any issues with the BT devices I have, so I need logs from you guys to debug.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] jjpprrrr:
