[Realme 3i ROMs, Kernels, Recoveries, & Other Devel] M.A.P:
​

LineageOS is a free, community-built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

What's working :

Audio

Bluetooth

Camera

EGL

GPS

RIL (Calls, SMS, Data)

VoLTE

VoWiFi

Sensors

Video Playback

Wi-Fi

Known issues :

Double Tap to Wake

Encryption

Fingerprint not working for et512 models. Users having other sensor can use it just fine

Not really an issue but, the device codename will only be displayed as RMX1821 even for RMX1823 and RMX1827, it is only for displaying purpose and is completely safe for flashing on RMX1823 and RMX1827. All Realme 3 and Realme 3i devices share the same firmware

Selinux is permissive(Temporary. Will soon make it enforcing)

You tell me the rest:confused:

Reporting Bugs

DO NOT Report bugs if you're running a custom kernel or you installed any root implementation

Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)

If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless). Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

Instructions

Have custom recovery installed (Use this if not installed already)

Download the latest LineageOS Build and GApps(Optional)

Wipe cache, Dalvik cache, data (If you have done format instead of a wipe(required for decrypted data partition for the first time), reboot the recovery once or else it will end up with issues/errors)

Flash the ROM and GApps(Optional)

If the ROM doesn't boot and goes to recovery even after flashing the recommended GApps, then go to fastboot from recovery and type the commands "

fastboot erase para

"

and "

fastboot reboot

"

Enjoy the rom
