I9300 update Linageos from unoffical to offical - Galaxy S III Q&A, Help & Troubleshooting

Hi guys,
I have a problem with the Lineageos official rom.
Is there any way to update the i9300 from lineageos unofficial to offical without wiping data?

You can try dirty flashing. Make sure you make a backup before flashing anything.

first of all i don't understand why you want to get to official when you're having problem""...
But if you want to change to official from unofficial data wipe is recommended. You might get some problems if you flash over...and i am using latest unofficial build of lineage with unofficial alpha boffela kernal which works great.

[Q] From temasek's unofficial builds to official cyanogen nightly ?

Hello,
I have been using Temasek's unofficial cyanogen builds for a few weeks. They are awesome and I sincerely thank Temasek for his build work.
I would like to move to the official cyanogen nightly builds, mostly to be able to use the OTA updater and CyanDelta.
I have a rooted international galaxy S3 currently running V85 of Temasek's build. From the settings, I can access "CM Updater", which does find updates, but I am unsure if this is a safe way to go.
Thank you for your help, have a great day. :good:

Installing CM on SGS2 via Cyanogen Installer

Hello everyone, I planned to install CM 12.1 on my SGS2, however I just wanted to ask, has anyone ever installed CM on their SGS2 with the CMInstaller? What CM version did you install/receive and when? And do they give the latest snapshot build? If I install now, do I get the CM 12.1 snapshot build? And can you update via OTA in CM Snapshots? Thanks

[HELP] Can't Flash CM based Roms: unifinished flash

I started using custom roms with official cm13. then been on many roms. but recently i discovered that i can't flash cm based roms. I tried with official cm14 and resurrection remix 5.8 nougat. the more recent updates. the flashing gets stuck halfway. sometimes it locks bootloader sometimes it doesn't. even on the latest firmwares. I'm currently on Aosp extended by Umang
change twrp if its helps
try with format data first in twrp
Check if the ROMs you flash contain firmware files, or skip flashing firmware after installing ROM.
