Chosen Solution

Hello, I have an iPhone 6 and I have broken my screen and scratched my back cover. So I took my iPhone to a specialist to repair this. He did a great job and the iPhone worked well. But then the new iOS 10 came out and when I tried to install them it crashed the phone. At this point it is brick an it doesn’t do anything. The iPhone does not react to conecting to the charger and the screen is black all the time. I can only put the phone to DFU mode but it does not help So far a I have tried this:

  • take it to the repair store to change the screen
  • unplug the baterry and then put it
  • update to newest software 10.2
  • restore in iTunes in DFU mode
  • exit the DFU tu normal via TinyUmbrella
  • flash it with 3uTools - says that it can not enter the recovery mode from the DFU
  • checking the screews in the part where the screen it put to the motherboard
  • charging it for the whole day - just have put it on charger - does not actually know if it charger Nothing works. When I tried to recover it from the iTunes it shoved error 3194, than after dealing with this error it shoved 2005 and after this 4014 and apple’s site or any others help does not seem to be useful as my iPhone is still not running. If any one has the same problem please help me. Thank you and sorry for my english - in czech i couldn’t find anything

Hello Teodor. I have noticed several similar questions on iFixit recently and I have an iPhone 6 in the shop right now that has a similar problem (although different history). I have not seen a definitive answer or solution yet. Here are the things I have tried, unfortunately without success, that you can try as well. Hopefully someone else on this forum will have other or better ideas (@theimedic, @tomchai, @benjamen50, @joshw ): I went through all of the recovery options, including DFUI used multiple, original Apple Lightning cablesI tried two computers, one Mac and on PC (with updated iTunes)I tried a new charge port, battery and screen assemblyI disconnected the front camera, back camera etcI tried with only the LCD, Digitizer and Lightning port connectedI visually inspected the logic board and found no water damage, LSD or anything elseI tried replacing the Tristar IC (U2) and reballing the NAND. I wish I had a better answer but perhaps this will kick-start a discussion.
