When you are facing the Error Code 4013 problem on your iPhone or iTunes or iPad. If you realise this error problem and prepare fix it. Now you can check and read out this below blog post to get the best simple and easy solutions to this Error Code 4013 iPhone problem.

 This iPhone was fixed before, so root it and test it. But it still reports the error code 4013. Observing the motherboard, we find the weld marks on motherboard baseband chip and baseband power chip. 


 Repair Process:
1. Doing BGA Reballing Stencil again and weld the baseband chip as well as the baseband power chip. Then connect it to computer to root. We can see the white Apple logo appears and it gets stuck at the grey progress bar.

 2. Based on the repairing experience, we know that this kind of trouble is caused by NAND Flash IC. Use multimeter to test each power supply circuit of NAND Flash and they are normal.

3. Remove the old NAND and replace it with a fine removed NAND Flass. It can enter activation interface, so we are sure the NAND Flash is damaged. The faulty NAND Flash is shown in below picture.

4. After replacing a new NAND Flash, it can enter the system normally. Trouble is removed.
