Q: ipad4 restore/DFU restore failed
Just passed by warranty period it starts to have blue screen, App store asks $299 to replace for a new one, so it sit in drawer for a while. Now I learned a bit so I tried to connect to a PC and installed latest 13.3.3 iTune, after failure I removed other USB devices tried different port stoped antivirus etc:
1. first I entered upgrade/restore mode, tried upgrade and it starts to download for along, after download it shows nothing and I thought it failed;
2. I restarted iTune or ipad4 and chosen restore, it failes with error 14;
3. I then tried a few times both upgrade/restore all failed at error;
4. Then I tried to enter DFU mode, use restore still fail.
5. I checked log file and quite match this case: https://discussions.apple.com/thread/5376586?start=30&tstart=0
I can't do it because I use Windows7/PC, if I use terminal to connect ipad4 I get to know comm port - but PC to ipad4 is USB cable iTune
6. I can't find any command list or how to use console under DFU with ipad.
7. I worked 3 hours and now ipad4 always shows image like I connected to PC, even in wall charging, and I can't check the charging status.
8. Before I doing these, the screen doesn't work property, messed up or so, so possible h/w problem?
