About ROM

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.

Could I flash this over my current LineageOS 15.1 of @CaHbKaUp (without a factory reset)?

Both ROMs are not signed so no migration is necessary.
Backup in twrp and then wipe the caches and system.
Do not wipe the data.

Thanks for this ROM, amazing that I now have android 8.1 on this device. Only issue I can see is that OpenGapps doesn't yet support 8.1 so flashing older versions (at least when I tried 8.0) results in an error

This GApps pkg is for Android 8.0.x only, Please download the correct version for your ROM 8.1.0 (SDK 27)

I have found this: https://forum.xda-developers.com/redmi-note-3/development/gapps-opengapps-t3720449
Have not yet tried updating. Perhaps you could give it a try and let us know...

Activate and open the Developer Settings, tick on the Terminal. Then type into the Terminal "reboot recovery", maybe you need before to type in "su". Then you hopefully can boot into your Recovery and get SuperSU.

I also cannot boot to Recovery by pressing Vol down and Power. After i flashed SU, i installed a Root App for booting to Recovery. This Solution is actually the best.

I typed reboot recovery at terminal the command cannot be found

A bug with your unit or this Rom?

 

[risant]

this rom... no problem with lineage 14.1.....this is just a minor bug

 

[fedex_742]

thank You! I've been waiting from december for this, enter to this forum time to time, my tablet its gonna be so happy...

First thanks a lot for the effort!
I tried the new 15.1 build, it looks great, the only bug I recognized is ghost touches. So if I use the screen keyboard suddenly it's gone because of a ghost touch to a different screen region.
There's a developer option to show fingertipps on the screen so I can see that there's touches on parts of the screen where there are in fact none.
I don't have this behavior with lineage 14.1. on the same device (flashed back and forth between the versions).
Also there's an option to set the touch reaction time to "long" but that didn't fully solve the problem.

Thank you Very much! Great work!!

I don't have this issue, Pollux Windy ROM.

hi guys, I'm new here ...great forum, great knowledge
i would ask, if that is a general problem with the recovery.

i had an crash, don't know why, and had to reflash the tablet. so recovery via terminal was not possible.

is power +volume down now working? i would like to test that image.

thanks for help and answer ...
