iPhone 6 dead Please Help!
Hello, i was working on about 20 iPhone 4s with nearly 100% success. So i have some experience in repairing Boards and replacing BGAs and other stuff.
Now i have my first (own) iPhone 6 with water damage.( Apple Juice )
I did clean the board with 99% Iso. After replacing Backlight FL and Connector the phone was running and connection to iTunes. ( At this time i should have made i backup but i didn't )
After checking all function, Touch id was not working. Suddenly around the LCD Connectors i feel a strange heat und the backlight Diode was burned.
So no backlight . I replaced the diode but still no light. So i replaced the Backlight Booster IC . Still no light.
Also no booting. iTunes detects an iPhone in Recovery Mode without Serialnumber. I removed the Backlight Boost IC and still the same.
I can't find any shorts on any Power Rails.
The only thing i found is that there is no signals on I2C0 Bus. SDA and SCL are always High. I think there should be at least some signal after switching on ? Could a dead Chestnut U1501 prevent the phone to boot?
I have no spare parts at the moment. Will iPhone 6 boot without Chestnut ???
I only want to get my Pictures. No LCD is needed.
Any Ideas ??
