Did not root the device. I used Odin to flash TWRP to it, then installed /e/OS.
The problem is - after few minutes of inactivity, the phone restarts itself for some reason.
What could be the problem? Thank you in advance
There was also a patch available, that I did not flash, because the link for the patch is broken
Could this be a problem? The patch is for the sim card usage, I use the phone with no simcard right now and still, it keeps restarting itself.
I have tried to flash the stock rom, then flashing the patch, then flashing /e/OS.
Still, the problem persists, after a few minutes (maybe even 1 min.) the phone reboots by itself.
Should I try an older version of TWRP? Or maybe flash a lineageOS instead of the original one first? But I can’t find lineage for i9305 anywhere.
PS sorry, I misread or misunderstood you. The system.zip seems to have flashed without error after you flashed a stock ROM !
The patch just downloaded fine for me. One thought, when you do download it, I see it named system(sim_support).zip I would suggest you name it to remove “( )” – say system-sim.zip in case the brackets might fail syntax idk.
I had (I still have but don’t use it anymore) also a Samsung Galaxy S3 LTE (GT-I9305) but I have never been able to use Lineage OS or /e/OS with it.
Each time I tried to install one of them, I lost IMEI number so the phone was unusable (IMEI was back when re-installing stock ROM).
I never found a way to have a usable install.
