Hi, here's a guide on how install crDroid 7.5 (A11) on Redmi 8
UPDATE: THERE'S 7.5 VERSION AVAIABLE, IF YOU ARE USING 7.4 FOLLOW THIS STEPS TO UPDATE WITHOUT LOSING DATA (NEW ROM IS IN MEGA FOLDER, ):
1- Reboot in recovery
2- Go to Wipe -> Avanced wipe -> wipe dalvik, cache and system
3- Go to Reboot -> Recovery
4- Now follow the normal guide from the flashing of the .img file as system image
VERY IMPORTANT: DON'T FORMAT DATA AFTER FLASHING GSI FIXER OR YOU WILL LOST ALL YOUR DATA
Features:
- All functions of the phone work (face unlock, fingerprint, voLTE, voWIFI, hotspot, bluetooth, fast charge, DT2W, ...)
- Magisk safetynet passed without flash nothing (screenshot at the bottom)
- Permissive Selinux by default (in settings is writing disabled, it's wrong) but you can switch to enforcing with
SelinuxModeChanger app, apk at the bottom
What doesn't work
- Nothing if you use fixes below
Note 1: You may have problems with the brightness or sim calls/sms, there are solutions:
- For brightness: Open settings -> Go in "Phh Treble Settings" -> "Misc Features" -> Scroll until you are in backlight menu -> Select "Force alternative backlight scale" and "Enable auto-brightness overlay" -> then deselect both and reboot
- For sim calls: Open settings -> Go in "Network and internet" -> "Mobile network" -> Tap on "Preferred network type" and select "GSM/WCDMA/LTE" or "Global" (try which is better for you) and then reboot
Note 2: If you fing bugs tell me in comments, maybe I could help you (I'm not the developer of the rom)
IMPORTANT ADVICE:
I am not responsible for any damage caused to your device by not following the steps, all the steps were tested on my personal device and are confirmed, my device is Redmi 8 4/64
