[ROM][UNOFFICIAL]Lineage OS 17.1

[EinTim23]

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.

Base source code is available in the LineageOS Github repo. And if you would like to contribute to the project, please visit our Gerrit Code Review.

Instructions :

• Download Twrp, GApps (if you need them), and Magisk (Version 21.4 or older).
• Flash the downloaded TWRP via fastboot
• Boot to recovery
• Flash the latest build and Magisk.
• Flash GApps and any other necessary add-ons

Known issues:

• Carrier Video Calling (ViLTE)
• Do bug reports in the comment section

Downloads :

• Redmi 6a(cactus) Download
• Magisk: Download
• Recovery redmi 6a: TWRP OrangeFox
• Google Apps: OpenGApps (use arm/10.0 nano gapps)

Reporting Bugs

• DO NOT Report bugs if you're running a custom kernel or you installed Xposed
• 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 /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
• If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

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.

Hi,

Thank for your files.

My phone bootloop, so I think I'm missing the installation of no-verity-opt-encrypt-6.1, lazyflasher-no-verity-opt-encrypt or Disable_Dm-Verity_ForceEncrypt_12.27.2019 zip files, but none of them work !

I don't know when and which version to install with your tutorial.

An Idea ?

Thanks

EDIT : Finally after having downgraded to MIUI 11.0.4, everything is functional with your instructions! Sorry.

 

[king76qc]

Well, my phone finally works with MIUI Global 11.0.9.0 (PCBMIXM). I can't use these files, but can I use another tutorial? Or install another Stock ROM with an older version? (downgradre)

Edit : File 11.0.4 here https://www.mediafire.com/file/5b85...191029.0000.00_9.0_global_a814b916b1.tgz/file for Mi FlashTool

Thank you @EinTim23 . This was a much awaited ROM for my Redmi 6A. Performance and usability much better than the stock MIUI stuff.

There's just one bug I have though... I can't receive or send sms's. Is there a fix for this?

Ah no worries... I did a full system wipe with twrp and started the installation process again. Seems I did not format my data partition the last time round. Everything is working 100% now.

Thanks for the Android 10 ROM! I found this ROM is better in performance and battery life than the Android 9 ROM I had used (PE+, Arrow OS)

 

[muhdizzatfarhan]

Bug report:
1. Apparently LED notification did not light up when charging :/

See if you can attach a brief logcat when you plug in the charger.

 

[houstonp001]

@EinTim23 , do you know what the best SD card specifications are to be used for an extension to the internal storage? Really loving this ROM... Just need more internal storage.
