Chosen Solution
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?
What’s the point? You dump the image, restore the phone, it may work. But when you write the image back, you still end up with a dead phone.
