Hello. If you could please help me understand what I am doing wrong...

This model, Macbook Pro 2019 16" A2141, 512GB, EMC 3347, with T2 Security Chip, had 4 NAND Chips shorted in 1 wing (U9100, U9200, U9300, U9400) and it has 1 more in the 2nd wing (U8600) BUT NOT shorted. All chips are TSB4227 TOSHIBA-KIOXIA SN4192TWNA12014 BGA110 128GB. I got 4 new nand chips for 1 wing and programmed them by specific position of course with JCID P13 programmer.

I also replaced the tps power ic for the ssd.
Now all rails come up, including the ssd rails 0.9v, 1.8v, 2.5v....

MacBook Pro 2019 A2141 820-01700 NAND Issue Stuck in DFU

Ok, here's an issue ive got on a A2141 820-01700 MBP 16' 2019. No signs of life, 5.06v 0.0a on usb-c meter, on each 4 usb-c ports.

Nand voltages are missing.

I've found no shorts at all so far, no signs of heat via thermal camera either.

Thanks​

Hello people. I have undertaken an upgrade from 256GB to 512GB. I have another A2681 board that I sourced NANDs, resistors and capacitors from. Yet when I try to restore the firmware in FDU mode I get the error 0x23 (35) (error formatting the NAND). Could it be the faulty NAND or I have missed something? Thank you...
