[ROM][non-GSI] Unofficial Pixel Experience P

[AndroPlus]

I built non-GSI Unofficial Pixel Experience P

Download:
https://drive.google.com/open?id=17lDJ-aOInCXdHQf8KXtoksEhZJgz7gS6

Changelog is too big for xda, so it's included in download folder.

If you are using Global /China Stable or third party rom (Xiaomi.eu), please download China Developer from here (search for "小米MIX3最新 开发版 线刷Fastboot完整包点击下载") and flash it, then flash PE system.img.
It seems current stable rom has some bugs in vendor or firmware (e.g. Google Camera is laggy).

Please note this rom is not maintained as my daily driver is FlokoROM GSI.

Working:
Camera (including 4K video)
Wi-Fi
Bluetooth (audio, in-call audio)
GPS
NFC
Dual SIM, Dual 4G standby
VoLTE
Fingerprint
USB PD
Wireless Charge
Sensors including proximity
AOD

Not working:
Slider (actually it's working, but no app to handle)
OK Google detection in any screen
Bluetooth call for some users/devices
Android Auto (display flickering)

Google Pay should work if you use MagiskHide Props Config, but I can't test since my country (Japan) uses hardware level security (exclusive for Japanese models) for payment via Google Pay.

Installation:
Currently generating ZIP is broken, so you have to install images one by one.
1. Flash the latest *Official* China Developer ROM (xiaomi.eu rom is not supported)
(If you are using other roms before, please wipe data)
2. Download and flash system.img
3. Download vbmeta.img and flash it with this command:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
4. Flash Magisk

Is this different from the one on gsi thread, thanks, button mapper gets assistant working really good. Actually I have set it to open gcam with press, double press for screen shot and long press for assistant

seems your latest build is stuck on G logo and will not move forward from there using latest Xiaomi.EU Rom

got it sorted had something to do with encryption. for some reason some apps still say this rom is rooted despite me not having magisk installed. always on display does not seem to work. ambient display does show notifications but there is no always on option like it is shown on the screenshots.

So it's the same build as on the gsi thread, thanks for answering

hey AndroPlus,

Thabk you so much for putting this together.
I am wondering if this has any built-in guesture navigation like MIUI's ? I do prefer vanila android over miui in general but the gesture navigation is pretty nice to have.

thanks!

it does not have miui navigation but you can install fluid gestures and get it working almost the same. i also would like to report that the bluetooth issue is still present. for call audio over BT the magisk module fixes it hope to see it included in future releases.

Anyone having issues with AOD? I've only got 2 options, wake for notifications and display music. Should be 3rd option for "always on" but missing.

Yeah same, how about not receiving messages on 4g, only get messages on 3g

Fixed AOD display with a magisk patch, not tested the messages yet

Please DO NOT use Xiaomi.eu rom as the base rom as it has fingerprint prop for MIX 2S!
All GSI rom uses fingerprint prop to detect device, so it breaks device detection
Only official rom is supported.

For the message in 4G, my carrier can receive message on 4G, so maybe it's APN problem or something.

I tried both official Chinese and global ROMs as a base but it kept boot looping and wouldn't go to the splash screen. What base version do you recommend?

Only Xiaomi EU allows the ROM to boot for me however there doesn't seem to be any issues. ROM runs well.

Hmm, I've installed the original PE ROM coming from a weekly EU build but it didn't seem to affect anything for me. My install process was China Dev > EU Stable > EU Weekly > GSI. What side effects were expected if coming from an EU build?

Also yeah, it seems that the latest commits for GSI ROMs did something at least to the Mix 3's APN settings. During previous builds I couldn't get SMS/MMS if 4G LTE is enabled, but now I'm having no issues whatsoever.

Finally, I've been testing Google Pay in more locations... it seems that some terminals do activate properly and I was able to perform transactions, but in others they either don't pick anything up or will result in a 'Please Present One Card Only' error. The last bit is interesting since this has been an issue during the early days of NFC wallet payment, and curious that it happens here. Might be some build.prop setting that we can exploit?

The side effects are:
Some settings doesn't appear (e.g. Always On Display) and doesn't work correctly
Overlay (configs related to brightness, doze and other system functions) for MIX 2S is used and you can't use dedicated configs for MIX 3

I see, now I know why the brightness settings are a bit off even with your Magisk module installed. Ambient Display works for notifications at least, which is what I prefer over AOD. Right now I have no urgency to change, but good to know the differences.

So to get those configs right, I would have to flash a China ROM image, then flash GSI into system. Is that correct?

Yes.

 

[jjsoviet]

Yes.

Flashing China Dev via TWRP as system image should be enough right? I wouldn't want to use MiFlash to do so because I'd like to preserve my TWRP and its backups. Would be way easier to TWRP backup > flash China ROM > boot > flash GSI ROM > TWRP restore > boot to save time.

Flashing vendor image should be enough if xiaomi.eu doesn't change other partitions.
System image is not related as GSI image overwrite the system image.
