Pèndrive KINGSTON DT50/32GB : Controler : PHISON PS2251-07-V

May 22nd, 2019, 8:54

Hi all.
I intend to upload all the cases I make with Rusolut.
This way if someone finds a device like the one that has already been seen, you will only have to open the case and get the data.

I start with this case in which I am having trouble reading the nand data. I find many bit errors.

Thank you.

I have already sent the message.

I have to say that each and every one of the emails that I have sent you have answered me. I am very satisfied with the after-sales service (It is my personal opinion).

A greeting.

Depending on chip will can test new Read Retry here (if we didn't already :)) and hopefully fix most of errors.

Once the <UNITE> is done you have to set the block size in 256pages.

This way in each block will go all the pages ordered from 00 to FF. In my opinion it is better to take the position as a page number, for possible reading errors.

I upload the structure of the NAND in a file, although there are some fields that have not yet been deciphered.

Then sort the blocks by LBN, sort and filter, and sort the pages within the blocks by position.

I'm quite a novice in this, please, I feel if I'm wrong in some things. I can not get results for the moment because of the immense number of failures in reading the NAND.

A greeting.
