Greetings everyone,
Well, the title says it all, I have two devices of the same kind, one is working 100% the other got stuck at Android's "No command" screen, so, here we begin:
After some extensive search I figured and found out how to use the working tablet to retrieve the .img files that create the Android OS work, I tried plenty of tools but the one that worked out the best was rkDumper v103, and Oh it was so satisfying to see all those little .img bastards get retrieved, however, here is where it got tricky, the working tablet obviously gets into recovery mode because this is needed to retrieve the files, BUT the crashed tablet doesn't get into recovery mode, the buttons work perfectly, volume +&- and power, yet the USB port is utterly f***ed up, and it is so badly that a recovery using the port is simply impossible, and here is where most of you experienced people will get what the problem is, every method described and available almost everywhere in the net describes how to use ADB, or how to use Flashing tools, even there is a Rk AndroidTool but all of these as you would already have guessed, are useless because, they need a working USB port, so here I am stuck with this problem when I saw there are other options.
There is a UPDATE from external and UPDATE from rkimage, and I know these two are the ones that could solve this problem, however, I have yet to find a way to cram every file I retrieved from the working tablet, mainly because they exceed the 8 GB in total, I know that my only chance to recover the tablet is with the SD choice, but every darn tool that promises to do this like for example SD_Firmware_Tool asks for a firmware, a .img unique file, and I've got like 10 of those, including System, Boot, Recovery, etc etc etc. Can't select a single one of these because it pops an error screen, I assume all my .img files need to be merged but I have no clue on how to do this, somewhere a guy told me to pack everything as a .tar and then change .tar to .img and name it UPDATE, it works partially mainly because only when the memory is 8GB can be recognized by the tablet but it can't hold all the files, a 16Gb SD can't be recognized, it doesn't even mount, and since the file size exceeds 8 GB the attempt failed miserably.
I know I have a solution at hand, but honestly I can't see it, the only thing I know for sure is that any method involving USB connection is not an option.
Would you please help me out?
