So hocuspocus69, one last question for you. One of your first steps is to make a full TWRP backup. But I have a new stock system without TWRP, and I would rather not install that. Furthermore, there is no real data to backup. That said, I have read stories of IMEIs disappearing, etc, so to be safe I decided to make a full backup using SPFT. To do this, I used the scatter file from the current stock firmware as guidance, and manually typed in ~20 readback ranges showing start locations and lengths for the partitions to be backed up. Then I ran it, and it dumped these partition backup files to my computer.

In your opinion, would this be enough to recover from some type of disaster, in particular, the potential loss of the IMEI? On a side side note, I did grep through the nvram partition dump file, and I could not find my current IMEI. But I trust it is there if the readbacks did what I was expecting them to do. Anyway, thanks in advance for any further comments you might have! So hocuspocus69, one last question for you. One of your first steps is to make a full TWRP backup.

Anyway, thanks in advance for any further comments you might have!it's right if you haven't data to backup you don't need TWRP your method of backup in theory is right but i'm only afraid about error in readback ranges i don't know where is located NVRAM partition.better will be to dump full rom and after use something like dumpsplitter but i never try it IF you find in your NVRAM partition dump file a reference to MP0B_001 file you have the IMEI that is stored encrypted inside it BUT I continue to prefer TWRP method!:-). Hi, Thanks for the scatter files. Programma ccalc ratchet konstrukcije diller kurbackogo. I was able to make the change to 8gb however I was not able load the TWRP recovery with flashtool. When I chose the TWRP recovery and the 8GB scatter file it gave me a checksum error and would not let me proceed. I imagine this is because the TWRP recovery is bigger than the original recovery. I had to root the tablet and flash the recovery using flashify app. Could you explain once more how to flash using flashtools?
