Hey Guys, got a macbook here where I think it might be dead Nand but just want to check with you if it might be something else.

At first was no power completely dead. Took board out didnt find anything obvious like short etc.. Did "revive" from another mac and saw shortly apple logo and battery afterwards charged again. But no boot.

See Sofix Measurements on port attached.

Checked some voltages again:

20V on all USB C - Battery is now charging
PPBUS_G3H = 12,58V
PP5V_G3S = 5,146V
PP3V3_G3H_T=3,36V
PP1V8_SLPS2R = 1,8V
PP1V8_AWAKE =1,8V
PP1V1_SLPS2R = 1.1V
PP0V8_SLPS2R= 0,8V
PP1V2_AWAKE = 1,2V
P3V3MAIN_PGOOD = 3,3V

For the SSD, the main voltages i think are present:
PP2V5_NAND_SSD0 =2,5V
PP2V5_NAND_SSD1 = 2,5V
P0V9_LX1_SSD0= 0,9V
P0V9_LX1_SSD0 = 0,9V
P1V8_LX0_SSD0 = 1,8V

other side looks same.

When trying to restore with another mac:

DFU RESTORE = AMRestoreErrorDomain - 0x23 (35))
Error while formatting nand

DFU REVIVE = AMRestoreErrorDomain 0x6 (6))

Would you guys say dead nand or try something else ??
Thank you!

From one day to another it stopped working. Tried to turn on, but stayed black. no water damage, just alot of dust inside. cleaned it up

battery was drained, macbook was not charging.

after revive in apple configurator it charged. showed apple logo for a bit and then stayed dead.

no fan spin, no core voltage no external video.
