Try restoring the iPhone using 3UTools You may have a better chance doing that. If it says clean flash completed then it seems to be stuck at the initial setup boot for some reason. You can try force turning the phone off and on using home + power button for 10 seconds after clean flash is completed and phone has been stuck on there for 5 minutes.
It appears that you have tried alot of things and they didn’t help. So this is just a shot in the dark…it has worked for me in the past (I don’t know why, but read it somewhere and thought “What do I have to lose”) Heat up your phone a bit…using a hair drier, heat gun or something safe…just to about 80 C or so…while it is hot, try the restore. I have gotten past this same issue with a couple, as well as Error 1 and a couple others…It’s definitely not a “FIX” and wont address the why of what’s going on even if it did work… but may get it over the hump to get it going.
Try putting your phone into DFU mode. To do that press and hold down both the Power and Home buttons until you see the Apple logo. After it appears, let go of the power button and keep holding down the Home button until you see a screen that says to connect to iTunes. Plug it into your computer and it should say that your phone is in restore mode. Click on Restore and see if that works.
