[Q] Using the rkflashtool to backup and restore a RK device
Hi! I read about this great rkflashtool tool here on xda and I'm experimenting with it. I've been able to make it work but I found myself in this situation: I backed up my device (CX-919 with 8GB flash) using the command
rkflashtool r 0x0 0x1000000 > backup
Probably the size to read is less than 0x1000000 blocks, but I supposed that the relevant portion was being transferred anyway.
Then, I thought that simply:
rkflashtool w 0x0 0x1000000 < backup
was enough to restore the situation as it was. This procedure seemed to work with a tablet, but not with the CX-919, which is not booting anymore. I tried to look into the beginning of my 8GB file and the content is the parameter data as expected. Is this usage of the tool wrong? Can't I use it like that? Or maybe the concept is correct?
Also: do you have any advice on how to fix the mess I made?
