Hey [MENTION=5970333]markakash[/MENTION] , I'd like to build AOSP with your kernel and device repos for the Xiaomi 9....

Do you have any hints how to build the kernel (on Linux)? I was trying with the instructions from [1] but it fails quickly...

Followed these instructions and booted up with no issues, but still seems to be some encryption problems when loading TWRP again (showing garbled folder names in internal storage). Will formatting data again fix this without removing the ROM, or is there anything else I can do?

EDIT: Never mind, seems to be working fine now.

Did a fresh install, not dirty, on the 11/17 version with vendor V11.0.2.0.QFACNXM and the assistant is fixed in apps like Maps and such, but regular assistant voice recognition still not working on lock screen or otherwise. Tried using the vendor 11.05 version people are linking in the thread but my phone just kept booting back into TWRP with that. Any reason we have to do so many Format data wipes for this phone? Other phones have been cool with just wiping system and flashing the ROM...

Because of encryption
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Running on top of the recommended EEA ROM and noticed fingerprint detection is very erratic.

Setting the FP up works well and after that it's either hit or miss. When locking the phone, sometimes it unlocks perfectly and sometimes there is zero fingerprint detection unless the display is turned off and back on a couple of times.

Also noticed that the fingerprint icon is visible all the time on the AOD. Does anyone know a way to use root access to hide/remove the FP icon altogether?

I'd prefer to have it disappear just like it does on the miui AOD to prevent burn in.

I have two problems / bugs. First, I charge my phone with a 27W charger but sometimes it stop charging a few seconds later I had connected it and I have to reconnect it. Second, I think that minimum brightness is too high in low light conditions. I know it should adjust better with a daily use, but what I don't know is what's the function of the lowest brightness, it's a bug? It's impossible see the screen.

Bug: USB isn't working in OTG/host mode. I have two USB headphone adapters, when I plug them in it only pops up a USB notification and it asks whether I want to be the controller or the client, and it won't let me select controller.

Similarly, charging sometimes only does slow charging even though I have known good(not even questionable) QC3 charger and cable.

If you haven't installed any other custom ROM so far your device is running under an official ROM anyhow. Then you can simply proceed with:

- Unlock bootloader (you'll lose all data).

- Flash TWRP (as said already Mauronofrio's works perfectly with Android 10).

- Flash the custom ROM of your choice.

Only in case you want to change between custom ROMs it's highly recommended to flash an official ROM in between.

Hello,

ROM works fine for the most part, i noticed the following things

- phone app isnt work. everyone who calls me i get "unknown caller" in my screen

- also when people call me they dont here a sound.

- i used other phone apps, butt when they call me, i get "unknown caller"

- tryed my simcard in my older phone wiht LineageOS, there i get a contact name when i get called instead of unknown caller.

so i think there is a bugg, i dont know if other people got this problem ? Or know a solution

format data

adb sideload in old TWRP (I think 3.3.1-30):

twrp-3.3.1-37-cepheus-mauronofrio.img

fw+vendor_eea_11.0.5.0_cepheus.zip

PixelExperience_cepheus-10.0-20191121-1116-UNOFFICIAL.zip

It was simple and very fast. Restart, setup system and flash magisk.

Maybe one more restart between steps above as was discussed earlier. I dont remember.

SQLite for ARM aarch64 devices v1.3 for database update as is commented here: https://xdaforums.com/showpost.php?p=79688076&postcount=235

But even with this, GPay does not work, I think that problem is somewhere in /vendor/etc/libnfc-nxp.conf and secure element position (SIM, HCE). But it's only my guess, I'm not an expert.
