Check all the power rail on the chip itself with diode mode. One is shorted.

Do you have a pinout diagram?

This listing says it converts a BGA315 chip to a BGA110 outline. It says it supports various iphone, ipad Mac Mini iMac and M1 M1 Pro MacbookPro models.

It is very had to find BGA110 chips for M1 Pro models at the moment (KICM223, 8T85 etc). Is this a solution so that we can go for chips like K5A8 on M1 Pro models? Has anyone tried it?

Today I tried with a new batch SDSF on A3112 and I can confirm it works. Cannot believe that P15 programmer gives no errors, but it produces a short on the board.

I have a question about the JCID P15 programmer. Is it a great tool? Can you customize the NAND flash memory, or does it have to use the factory NAND firmware to ensure proper soldering and avoid problems during DFU resets?
