[ROM][10.0] LineageOS 17.1 for Redmi 8A (olivelite) [UNOFFICIAL]

[TechyMinati]

LineageOS is a free, community-built, aftermarket firmware distribution of Android 11, 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.

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

Nice.

 

[David-538]

Hmm... Why does the telegram groups report bugs that are not mentioned on this Xda tread ? Is the telegram groups misreporting bugs or did you forget to mention those bugs ?

 

[QuantumBeat]

This is awesome!

Will flash, looking to get rid of all the pre-installed apps for a long time now

What is your experience so far? How long is it running for you?

 

[UltraGOD]

Which recovery do you use for flashing? TWRP standard won't work (error 255), the 64bit versions I found give me a black screen on the olivelite.
Would be happy for some help
Went back to Havoc 3.8 now, the only custom ROM which works fine so far, but GPS is crap (that is my main issue...).
Many thanks in advance!

What about havac 3.7 and 3.8 which is more stable and have less bugs?

 

[UltraGOD]

Yeah, used the Havoc 3.8. It is faster than the vendor MIUI, but still not what I am looking for.
My major issue is GPS. But I do not know if this is a hardware or software (ROM?) issue.
I'm playing GPS related games, and GPS very often does not match the actual position, plus games running slow on vendor ROM, bit better on Havoc, but still not ideal.
GPS tools like GPS fix or GPS booster only have limited effect...

Also tried some GSI ROMs, but they do not work on the olivelite. Whether the phone crashes when booting or nothing happens at all and it keeps stuck in the "Redmi" boot screen.

Hello,
I'm not good at flashing a rom.
For my phone I use orange fox official recovery and I also tested with TWRP. But when I try to flash the rom I always get a 255 error.
Can anyone help me on what is a 255 error and how not to get it.

to install the recovery I used the commands: fastboot flash recovery.img then I flashed orange-fox with adb sideload

then I tested to put this lineage os.zip on my SD card then flach it put 255 error and I also tested via adb sideload and it did not work

in the instructions to install it says to flach 64Bits Vendor but I'm supposed to find it where?

I'm sorry for my english which can have problems I'm not english and I use a translator (deepl.com)

I'm having exactly the same issue
Whether this is not a ROM for the Olivelite or we do something very wrong.
Weird that nobody was able to offer support so far...
The only custom ROM I was able to get to work on the Olivelite is the Havoc 3.8...

[yosi20000]

After try several recoveries - 255 error in all of them.

I install it as images (via fastboot).

I followed this guide to create system.img

How to Extract system.new.dat.br and system.new.dat Files

In this guide, we will show you the steps to extract system.new.dat.br and system.new.dat files which are part of Android custom ROMs.

(in step 5.3 it should by 7 not 1)

 

[Eltaba16]

I have a bug in this rom with whatsapp. I can not send videos through the application, or upload in the state. It only happens to me with the videos, since the images and other files are sent without problems.
