succesful flashed version 355
THIS IS A VERY RISKY OPERATION AND I ALMOST LOST MY PHONE!!
it didnt go as planned.
i installed twrp and created a backup (not of system, is that nesecarry?) to get to when everything got messed up.
and boi, did it get messed up...
problem 1: when trying to install the rom with QFIL for the first time i got a sahara error and the phone lost its OS. i wanted to reinstall the twrp backup as i got really freaked out about losing my phone. somehow it did not get into edl or something and i failed the installation process and ended up with a broken phone with inly TWRP installed.
problem 2: when wanting to reinstall the backup in twrp i got some error saying the \system partition was not mounted. searching online gave me a solution to this problem, but reinstalling the backup still gave errors. on startup i got a "unsuccesful encryption" error, which yielded a useless backup. also after reformatting i got again the /system not mounted error, but now with a "partition is occupied or used" error. even the solutions online wouldnt work, so my online solution was to flash the original rom with QFIL.
solution:
trying to flash the rom resulted in a 1: sahara error, 2: a file not found error and 3: a phone not in EDL error.
when using the QFIL flasher provided by BadCluster i got the first two errors, and there was no quick way of resolving this problem. the post from
@Nikorasu of another QFIL programm being used led to to the last error. this was good news as the file not found had been gone and now the only thing i had to do was putting the phone in EDL mode. MANY thanks to Nikorasu!!
trying to flash now resulted in an error where QFIL tried to put the phone in EDL mode, but failed to do so. a article online provided me with the following ADB commands to use. try to open to the bootloader/twrp recovery menu, and using the ADB cmd try to see if your device is connected (command "
adb devices"). if so, type the command "
adb reboot edl" and the phone will reboot in EDL mode. this was the only thing left to flash the stock rom back.
moral of the story!
1. only do this if you can miss the phone, this will save you a LOT of stress!
2. only do this if you can afford losing your phone!
3. in my case, the TWRP backup was pretty useles. only do this if you can afford to lose data!
4. THE MOST IMPORTANT ONE: NEVER GIVE UP! using the internet you can google every error and eventually get to a solution.
