Hi together!
I'm doing board repair as a hobby, just to see, what is fixable and what is not. Now I got an iPhone 6 that is not able to restore.
I tried the restore in iTunes and in 3utools. iTunes will stuck for ever (I let it sit for 2 hours without progress), 3utools will stop with a timeout at 20 percent ('Sending FDRTrustData'). The restore gets until the apple logo with progress bar and then nothing moves, no error message from iTunes. The device is still recognized by the computer. I tried on another PC, and other USB cables, new battery all the same.
At first I tried another connector - still the same. Then changed tristar - still the same. What I noticed yesterday was that in the moment where everything stops (when the apple logo with the progressbar appear) the PP5V0_USB drops from 5V to about 4.5V. At this time the phone draws about 0.5 amps over the USB. PP3V0_TRISTAR, PP1V8_SDRAM, PP_VCC_MAIN are all normal readings. No signs for liquid damage.
Any one an idea what it could be/what I could check next?
Thanks and greetings
