How to take a "image" of the NAND?
So I have this phone for data recovery. It is stuck in DFU mode for some reason, it wasn't yesterday though. This may be an insane question, but can I get everything on the NAND, get a image, save it as a file, then try to use 3u tools to restore it with keeping user data, and if it fails, could I restore the file back to the NAND?
Is this a good question?
