PS5 NAND SSD error 80871055

[domik100]

I'v got some SSD errors over UART so i reflowed the chips, replaced controller, now getting 80871055 error (SSD Banks IO Error Between SSD Controller). Reballed all 6 chips, still no help. Measured resistors beside NANDs, compared them, one is different - marked it in picture (others are 2,5kohm). Is this correct value for this res? If not could it be caused by bad NAND on other side (reballed it 2 times, nothing changed).

Checked now on other PS5 and as i thought, the value should be ~1.9kOhm, so the NAND chip could be our culprit or the SSD controller?

Is it possible to replace just the faulty NAND chip from other PS5?
Possible to buy it from somewhere or just look for broken PS5 board for sell?

I have the same error. Did you solve it?

Ho alcuni errori SSD su UART, quindi ho rifatto il flusso dei chip, sostituito il controller, ora ottengo l'errore 80871055 (errore IO tra SSD Banks e controller SSD). Ho rifatto il rballing di tutti e 6 i chip, ancora nessun aiuto. Ho misurato i resistori accanto ai NAND, li ho confrontati, uno è diverso, l'ho segnato nell'immagine (gli altri sono 2,5kohm). È questo il valore corretto per questo res? In caso contrario, potrebbe essere causato da un NAND difettoso dall'altro lato (l'ho rifatto il rballing 2 volte, non è cambiato nulla).

Ho controllato ora su altre PS5 e, come pensavo, il valore dovrebbe essere ~1,9 kOhm, quindi il colpevole potrebbe essere il chip NAND o il controller SSD?

Ho lo stesso errore. L'hai risolto?

Has being said that ps5 fat has 6 flash chips, 3 of them can be replaced without mejor hasle, but other 3 can not because have per console info. I own a ps5 with suspected bad flash , I can get perfect video from safe mode but cashes loading main system. weird artifacts and error codes saying that database is corrupted and another error code related to internal storage . This suggest that i have faulty flash memory on one of more of the three that are not replaceable , afaik there is no currently way to dump those flash chips. You could try to replace those chips that are NOT red ones (keep track of them in case you have to resolder them back )

Do the flash memory units have to be of the same brand? E.g. If I want to replace 3 Western Digital NANDS for 3 Samsung NANDS (from a donor board)?
