Guys, guys, guys, what's so simple about this method. You are linking to like a dozen threads, with like a dozen different colors meaning god knows what. And you are talking extraterrestrial.
My problem :
I have added a file "ENABLE_DIAGS" on my kindle, everything has gone to hell since. I'm stuck in diagnostic mode, I have removed the file, hasn't changed anything. I have the last Kindle 4, the black one. All I want is to be back in the main mode, worst case scenario reset the entire thing, no flashing or crazy stuff.
I have tried to follow the "Successful Debricking Begins Here", well it began, but there is no middle or end. Nothing happens when I start MfgTool thing. And in the device managed, I can only see HID-compliance device not the other one. At some point one of the tutorial says to delete the folders in Profiles, but then you don't give the files to replace it with...
No but seriously, I need something simple that works. It can't be hard to undo that, I have added only one file ?
