I have an iPad 1 which is unable to reboot at all. I tried to go in DFU mode, using Home and Power buttons. It's been detected by iTunes, when I try to reinstall from iTunes, nothing works. I have an 1602 error (every time). I tried on a Mac and on a PC, and my last chance is here before I throw it to the garbage :(
All I can see is the screen flashing (but no Apple logo, or any graphic). Do you know if there is a free software I can use to repair it or if there is anything else I can do?
