Well,
Why do i get all the super complicated cases in india for flash ,every bloody case i get is mostly new ,Has anyone worked on the Sandisk 820410PA1 Controller with TSOP48 NAND Which is 32768Mb to read but 16GB as printed on pendrive .This is Definately TLC IMHO ,The Controller is a QFP

Didn't have one yet but if it's TSOP48 you can always try to fix/swap the pendrive. If you get the memory dump first.

Hello,
I have Read the dump ,I will see if i have a donor ,I will also post here to see if anyone has a donor maybe ,But i have got little info on this Sandisk Pendrive , Perhaps Arvika has got his hands on this one for sure ,QFP controller package and TSOP48 NAND ,I though this one is gonna be easy :lol:

Hi,
I Will Send The Details After Scanning The Flash Drive On Scanner To Get Good Photo .BTW This is What Roman Wrote To Me " Sorry for bad news - this controller is a new gen of Sandisk CPU. Right now they are not supported. New 4xx family contains a new ECC structure which is XORed and partially encrypted. We are working on it now, hope solution will be within 6 month." .So PC3k Is Ruled Out Any Solution in VNR ? . Flash Extractor i Do Not Have ,Only Option Is NAND Swap To a Donor ,Has Anyone Tried This One

they are not talking about LDPC are they. as that is what it sounds like... but using scary gobbledegook language to make it sound harder (well, it is actually, but why not just say LDPC..)?
Seems to becoming more prevalent.

I don't think so it is LDPC. But of course I will check it if I meet such case :)
