Error 4013 and error 9 on DFU Mode
Hi All,
I just bought a second hand iphone 5s and update the ios to 10.2. It works fine for almost a day and at the end of the day suddenly the device blank screen and what i did was reboot it as the screen are not coming back after i press power button to awake it. The device will never reboot and stuck at boot logo. Throw me a panic cpu 0 caller kernel panic once before stuck at itunes logo.
Tried to perform itunes restore but keep getting error 4013 on normal recovery mode and error 9 on DFU mode.
Tried to remove front screen assembly and back camera that someone from the answer here suggested but still unable to solve my issue. Any other parts might have cause this? Your suggestion of potential fix are appreciated.
Local device repairer told me might be the u2 flash issue and not worth for a fix as to replace the ic is expensive, is that true?
Thanks
Is this a good question?
