Ship me the board and it will be done within 3 days. It is not rocket science. The device is still using LGA60 NAND Flash which is 64Bit. The same chip as iPhone 6 that apple haven’t change to E3NAND (PCIe 2X). I am not the Rossmann but I walk the walk.

There is so many suppliers to buy the chips. Only thing is you need to know the right suppliers who can supply quality products.

Since I have read the teardown from iFixit supposed to change their name to (I cannot fix anything). Every single device from the 2012 retina is not repairable as there is no effort to try t learn the system. I was working on the mac at component level repair and when we decided no fi is not feasible for me. If I were not going to waste my time more than 4 hours to diagnose the device, it is okay. When the CPU shorted, it is not going to get me work on it since I will have to spend at least another 4 hours just to find out if the CPU is reusable or not.

There is many possible way to fix if someone did not tempered with the boards especially so called repair shops, scrubbed the boards rubbing alcohol to make things worse plus the rice repairs. Once I see rice, I just tell them to take it back because rice is food that cannot fix anything.

The battery is glued on and it takes a little effort to replace as long as replacement is available. The touch ID circuit is repairable and no new logic board required.
