[ROM][T525][UNOFFICIAL] LineageOS 17.1 | Android 10.0 Q 20210419

Search This thread
I'm not responsible for any damage to your device of any sort.
By flashing this you take responsibility of anything that happens.
Process at your own risk!

If you want to check firmware - please make backup. Better to store all partitions, at least efs and may be modem.
I'm using nano/pico gapps.

Instructions

1. Install custom recovery
2. Download the zip(s) - firmware and Google Apps additional package (optional)
3. Backup all partitions (it least efs) and store somewhere - it need to do - because you can loose imei
4. Full wipe all
5. Flash firmware and gapps

Work
Almost all

Known Issues
- video record

Recovery
this is my build, the error with the screen off is still present, but I added an option for twrp with unlimited screen timeout, as a result, the screen does not automatically turn off.

Thank you for this build.


Does anybody else have the problem that picture-in-picture mode is not working?

I'm watching a video with the German sky go app. Pressing the home button takes me to home screen and does not show the video in the small window.

This was working with the Android 9 build.
The permissions are set for the app.

Thank you for this version.

Warning: I initially tried with GApps Stock (like I did with 16.0) and it totally messed up the system (Pixel Launcher crashed constantly, attempting to log in to Google account resulted in a black screen). Now, with Pico, it seems to work alright.

T520 is not just T525 without LTE. T320, T325 and T525 have Qualcomm Snapdragon SoC's inside, so most of the codebase can be shared between them. T520 has Exynos which is quite different.

Just updated to 20200724 with GApps Pico, Magisk and Viper4Android. Nothing out-of-the-ordinary stands out, so in all regards this appears to be a safe upgrade.

THX for taking care but it was my fault
I have not red carefully the instruction for recovery
I had an old version
Now installed the recommended one
for recovery: https://drive.google.com/file/d/1UeC...ew?usp=sharing
Here I have another question
when I go to TWRP -Install Choose the TWRP zip I only installed image not the Option Boot.
Was This OK?

TWRP is starting correctly and I have successfully flashed the image of June (1) & PICO.
BUT I have NO sound!!

How do I install the updates?

SO I will lose all my settings?
No, you won't. Data and Internal Storage will stay intact. This is the procedure I follow when I update from one version of e.g. 17.1 to newer one. Only when upgrading to a new major version do I fully wipe the device.

If you're unsure, backup your stuff with "ROM Settings Backup" and "Titanium Backup" before wiping anything.
