So, I was running 4.2.1, I downgraded from ***.10 to ***.08 and succesfully got TWRP, made a backup and downloaded the appropriate zip for cromi-kk.
Everything was going well (sort of) and after the zip was extracting/installing, a screen with 4 penguins showed up. Then three lines of something (looked like it was searching for disk spaces. The first was found but for lines 2 and 3, "not found" was reported.
Moments later, the tablet is attempting to load the new ROM, but finds itself at the bootloader screen, waits a few seconds, tried again but then loads back into twrp.
Today, i came back to the problem and may have accidentally formatted everything through twrp. No more zip file, no more OS, no more backup.
I assume I need to update the bootloader (and start all over), but don't know how.
I know, I know ... shouldn't have done so many things, but if someone has a solution to both problems or can point me to a thread where this problem has been solved (with the least amount of scorn and derision) I would be quite grateful.
