When your phone can't continue store photos, maybe many of our readers think the iPhone 6 motherboard caused this.
But we should test then get the conclusion,like the picture showed, we found the screw column was damaged .
This screwdriver has a flashing light on the back of the camera. According to our repair experience, it is known that photos cannot be saved should be the iPhone flash IC problem. Will it be caused by screwdriver column? So after measuring the camera, the EN signal was found to be in a normal state, and would it be a semi - connected state?
After scraping, it is found that this line is nearly disconnected. Is it the problem here? The photo is really not saved after installing to test. Connect the line, the fault finally comes out.
Next, removing the flash IC off and cleaning the glue of the weld plate, then we start to measure the resistance, he E2 pin of the flash lamp is found to have no resistance. This is the I2C bus that connects the iPhone 6 CPU with the rear camera and the flash IC. The details are shown in WUXINJI schematic diagram.

Scraping the lead to get rid of the possibility of broken line.

The camera can get the resistance and get the exclusion of CPU false welding, it should be disconnected line problem in the plate. The solution is to connect jumper wire from the E2 pin of the flash IC to the rear camera socket FL2329. As shown in Picture 12-1-5.
After welding the jumper wire, the flashing light E2 has a resistance value, install the flash lamp IC back, fault is solved now!
