Battery problems, bootloop, itunes error 4013
I just got a weird iphone.
The iphone wouldn't charge anymore, it was stuck on the charging screen.
So I replaced the battery, but now with the new battery I am stuck in a boot loop ( 3 sec on, 3 sec off). (And the problem with the old battery stayed the same.)
This is what I tried:
- Hard reset
- DFU mode
- New battery
- No front camera attached
- No charging dock attached
- No screen
- Those things combined
Now I got a little bit further, while in DFU mode itunes finds my iphone (only then) and I could press on "update". But while updating I got an itunes error 4013.
With the old battery I even can't get into DFU mode.
I don't know what is going on, can anybody help me?
My only solution I can think of is resetting the device, but I dont want to loose all the data on there..
Thanks in advance.
Is this a good question?
