>Install Google apk package zip of the respective Android system of the custom rom if you want this permanently I wanted this less apk version ofAICP custom rom so I didn't install the Google apks . But this is necessary for Google account and syncing data and payment apos.

The new custom rom installed flawlessly and Android system opened with home screen, some media app was giving errors at that time . Connact to wifi and setup magisk installed as app. Don't do anymore

changes to settings like setting up lock screen paswword and installing side loaded apps since I needed to solve this media app closing error.

Connect usb

Again connect phone to PC to fastboot mode and reboot to twrp image with adb.

>Choose wipe

>Data , dalvik ,cache ( not internal storage )

>Install Google apk zip if you want

>This will wipe all previous system storage files(pdf, camera imgs , songs ) which we have backed up earlier to PC.

> Reboot to system (not installing twrp app to system )

The AICP rom is working all fine no errors everything works, this custom rom has some good UI features and settings. Also it supports sound dsp which worked both speaker and Bluetooth earphones.

Don anythin now, magisk root modules, side loading apps u trust , password settings or even update to new custom rom again with Chiron twrp with adb. Just move the custom rom to internal storage and install with twrp.

Lineage OS has updated Android Images too.
