[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] makishima-shougo:
Hi all! I have Kindle Fire HD 8.9 (root, stock 8.4.9), locked with password. My niece tried log in, she enters the password several times, but could not enter, then she just turned off(press power off button). When I tried to enter, the system is don’t requested a password, language was French, and all of the data disappeared since the beginning of 2015. :( Yes, I know, I need to backup, but I keep going use it.

Later I known in this model, if lead many times an incorrect password, it launch a factory reset, or proposes to do so, my niece does not know English, so ...............

I have read a few instructions, and was able to rooted again and download to my computer directly from the tablet dump memory:mmcblk0 from /dev/block/*. This is the largest unit, so that it should contain all the data, also i download mmcblkp13 /dev/block/platform/omap/omap_hsmmc.1/ *. It is the user's data. All in *.raw format. Scan R-studio and other programs, but all I found was data information from the default firmware.

I read that when you reset, the data do not disappear completely. Then I found one file, I think it only indicates what happened:

last log file:

Maybe someone knows, there can be a way to raise the data may have some manipulation of data blocks or there are nothing here, all the data were erase and it makes no sense to do something(special firm ), so the question for those who understand?
