Hello, I have an iPhone 7 with error 4005. It do not switch to recovery mode during flash, and after few seconds give error 4005. I removed flash ic and check with my jc programmer , it read all data an, mac , etc. then I flashed backup from working one, and correct sn, macs and model. After soldering back situation is same - 4005. Then I took one flash randomly and solder it without any programming and sn correction , and after that phone normally programmed and powering on. But activation is impossible in this case. I have tried more times with other flash ic’es whit uploading original data but no success. What I’m doing wrong?



Check the CPU part, if it sure the NAND flash is ok, then the problem is on CPU.
