[ROM][BETA][UNOFFICAL] LineageOS 18.1 for Xiaomi Qin F21s Pro By A.I.V

[ygreenes]

i flashed this last night, and the flashing went just fine (surprise!) however i am barely getting connected to 4G, will lose 3g and even get 4G but not register on the network. is there any way to get to engineering mode or the equivalent to check and adjust relevant settings? or maybe someone can give me proper guidance?

Does talkback work in this version?

 

[talmid01]

Do you have the stock rom for this device? (in case something goes wrong...) I ordered now one of these, it has a great form factor.

I'm not sure if this project has been abandoned, but when I owned this phone, the keyboard backlight was a constant on and deplete the battery.

This Magisk module I discovered might be able to fix the issue.
Let me know if that works

My English is really not nice.l am so sorry for it.A good news is that I can nearly fix all the bug.ways are as follows
First, we can use the data just by changing a file,/vendor/etc/fstab.mt6761,my version is 1.1.1, it's a little different from 2.1.6, but just delete words after "block,"except "," like me.and reboot to recovery, format data and reboot system to find you can use data

Second, we can make system writable by changing the same file .this time we should delete words "avb" except "avb" in this the picture below

Reboot and find it works .
Third,l find way to disable lcd bottom light.change to /sys/class/leds/mt6370_pmu_led1/
Find file brightness, copy it to sdcard change it to 0.and recopy to replace the first file.finally chmod it to 440,right now it works.

As the picture above.if you really need,l can make a magisk module to disable the lcd bottom light,too.both can make it works .
At last.By the way l highly introduce you to flash the lastest phh pixel experience a13 gsi, it's really nice,

Second, we can make system writable by changing the same file .this time we should delete words "avb" except "avb" in this the picture below,there is also one thing that needs to be remind,when delete avb ,you must delete with the "," next to it, Don't leave two "," together

Also there you should not leave the "," at the end,

I can confirm this works. And the battery life after disabling the backlight is amazing.
However, there is some bugs i found.

- no VOLTE
- auto rotate doesnt work in any video app.

But its now became a nice daily driver. kudos A.I.V for making a huge progress.

Can someone give me a link of this launcher? Thank you very much

​

Edit:

- The buttons backlight need to do every reboot
- Fixed the VOLTE for my network.
- The screen rotation on videos doesn't bothers me at all since I dont use this for media consumption.

Overall I'm glad I revisited trying out this ROM. Thanks a lot its now my daily driver!

battery usage since last full charged. Includes 8 hours of sleep phone just idle with backlight off

Hi, i am currently on v3. When I'm connected to my bluetooth headset the sound comes out through the phone's speaker. Are there any workarounds for this? Thanks!

UPDATE: Got it fixed by enabling this option in phh settings > misc

Hi! Thank you so much for sharing this. Everything seems to be working smoothly except the lockscreen. Whenever I set any password it crashes. Hope you have a workaround on this. Great ROM!

I don't use passwords.

Is the Quick Setting app - which is specifically for this phone (assigns different functions to the buttons) - preserved?

 

[pwkpwkpwk2022]
