Macbook Air M2 A2681 NAND upgrade error 35

07-03-2025, 12:20 PM

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

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.
