[Help] Sansa Clip v2 bricked, NAND reset OK, what next?

(1/4) > >>

Darko:
Hi! 30 minutes ago I had perfectly working Clip v2, now it's dead. Or it appears to be so. "Crashed" or "Bricked", what's the differece? Rockbox configured and installed succesfully, but now it won't boot. Battery is/was at 100% charge.

I followed this
http://www.rockbox.org/wiki/SansaAMSUnbrick

Opened it. Unsoldered battery "-" wire. Shorted 2 NAND pins and plugged into USB (Windows XP SP3). Recognised as unformatted drive. Out of curiosity formatted it with FAT32, works as a fancy flash drive (980 MB).

I am really no expert with Linux, trubleshooting guide says I have to boot with Linux in order to access hidden partition with Firmware. Can this be done under Windows? Is there any utility to access hiden partition under Windows XP? Is my player really dead without a chance? Please help, say something, anything, I am all ears.

To add, I have Hirens Boot CD with some Linux, can I use that or you prefer Ubuntu?

saratoga:
You don't have to use linux, just its recommended since the instructions assume linux.  If you know the windows equivalents of those commands, you can use Windows.  Otherwise use a live cd or VM.

Darko:
Hey, saratoga thanks!

In the mean time I booted Mini Linux from Hirens Boot CD and GPart only sees 980 MB of space. There is no any hidden partition? Also tried some DOS programs from Hirens, same behaviour. Am I missing somethin?

in the recovery page it says this:
"Now you can access the hidden part of the NAND flash over that drive (reported by fdisk). "

------------

folks over @ IRC channel explained I need "dd" utility and that hiden partition is not neceserally hiden, its just a first empty space on that partition. I'll report as soon as i have something...

Thank you all
Darko

saratoga:
There are no partitions at all (well beyond the one you probably created when you formatted).  You've just got raw access to the flash memory.  

Edit:  Have you looked at that wiki page very carefully?  From the very first paragraph:

"Execute "sudo fdisk -l". It should report a drive without partitions, with a size of 979.75MB"

Where are you getting that there should be hidden partitions exactly?

Darko:
Well, in this sentance "Now you can access the hidden part of the NAND flash over that drive (reported by fdisk)." Maybe I misanderstood it or it is badly written?

I tried to format it inside Windows with FAT32 and it works as a regular USB Flash Disk, also copied m30pa.bin original firmware, but player still does not power on. Maybe I need to resolder battery again and diconnect USB power?
