iPhone goes to DFU mode after screen turns off
iphone goes to DFU mode after screen turns off .
it's ios 15.6.1 and can't update because if I try to update it goes to DFU mode.
Also I tried DFU flash but it fails at nand flash and itunes make error 9.
It doesn't go to DFU mode if I don't turn screen off
how can I fix it?
Is this a good question?
Is it connected to iTunes when the screen goes off to say it's in dfu mode? Try a restore but with a different cable and computer if possible.
