Connect the iPad 2 on computer and reflash by iTunes, it reports error 4013, we judge the problem comes from flash memory.

Use corresponding iPad opening toolkit to disssaemble the iPad Air2 and take off the motherboard, then put the motherboard on iPad PCB test fixture for the next repair operation. It is found the iPad NAND chip was repaired before, so we remove the Nand chip and reflash again, the error code is reported again. So we are going to directly repair flash memory.

After the flash memory is installed, it's normal when reflashing again, invalid SN is reported.

If the invalid SN is reported, it basically means flash memory has no problem, install the iPad Air2 NAND chip and turn it on directly.

Generally, blurred screen and reboot is caused by the flash memory problem, if you encounter the similar problems in the future, directly repair flash memory.

This NAND chip was repaired before, so we estimate the flash memory is false welded when blowing with hot air gun. In the past, the customers who had iPad Air 2 NAND flash memory expansion said that it did not take long to encounter new problem. So you need to be very careful on iPad Air2. The NAND flash is very close to CPU flash , the last repairman was prying from the inside when expanding NAND flash memory, we usually cut the shield from the outside and pry from the outside, this will be more safe. As shown in picture 16-12-2.
