Oh, many thanks! I'll try to get my tablet up and running again. The tablet crashed after having repartition and Los 17.1 for a month.Firstly, don't worry about your eMMC, you have a solid Toshiba "MMC_NAME=016G92"

ELAN, the touch control IC, generates an error and stops/slows the boot process. It is very easy to fix.
However, I note a second problem. One of the newest ROMs you tried, LOS17.1 maybe, had messed up some data on the 'persist' partition. Again, no worries, I attached a fix for that - install it from TWRP. Stock ROM will be stuck on boot logo without the fix.
It Boots again! Still dont know why it wouldnt flash the first time i tried... And because of the fix you included it booted. Now i can flash custom again!
@k23m might it be wiser to flash my persist.img backup instead of the fix ?
