C200V2 bootloader installed but no effect

(1/3) > >>

Hi,

(Saw some message in IRC, C200v2 is close to become unstable, Thanks a lot!! I am so eager to try it but... )

my device: c250v2 2G. (Version V03.02.05A).

get boot file here:
http://download.rockbox.org/bootloader/sandisk-sansa/c200v2/

I have copied the patched c200pa.bin to c200v2 root folder (in MSC mode, that has DID.bin and other files there), as well as the .rockbox.

Patched c200pa.bin:

File md5:  31cd171bf68608c54d19666d26362969 output.bin (I rename it back to c200pa.bin when copy to the device)
File size:  5243904 bytes

after safely remove USB, unplug USB cable, it show "firmware upgrade in progress", firmware ungrade completed, then shut off.

But after startup, it still show as original interface, (sandisk "Langage"selection in exact). Everything is still sandisk interface.

Did I miss any step?
Help please.


UPDATE: Additional information.
1) From sandisk forum, another user kindly provide his/her working patched bootloader, it is identical to mine patched one. (md5sum/size all match)

2)So, I think must be my upgrade steps is wrong.
I tried using OF menu to "reset all", format, still same result.

Also, I noticed in root folder the file RES_INFO.SYS contains some strings from rb.
(actually I have deleted all files in root folder, so these must be generated at startup)
From the zip file of original (from Daniel website)backup, the RES_INFO.SYS contains:
$strings RES_INFO.SYS
mmc:0:\
HOTO
mmc:0:\DID.bin
.SYS

But now, even though my c200v2 still boot to Sandisk Menu, this file contains:
$strings RES_INFO.SYS
mmc:0:\
rockbox
ockboxed
tusbar
mmc:0:\.rockbox\WPS\Rockboxed\mode-color-small.bmp

So, I have a feeling that RB bootloader does bootup, but somehow it always fall back to OF?

UPDATE:
3). I have tried using both patched c200pa.bin and .rockbox that works fine in other people's c200v2, but same result in mine. Showed firmware upgrade completed, but still boot into OF.

 ???

Same as here. Still nothing :(

BTW: my Sansa is refurbished. Is that mean something?

Don't know, mine is also refurbished. But considering the same binary/firmware works on all the c200v2, I guess it is just some race condition/PIN readout cause the difference.

Actually, I play around the code of dualboot.S, and messed up this critical piece of code. my sansa is a brick now.  :(

tofmin:
Sad to hear that :(

Maybe there is still chance to unbrick?

lazy:
i have a c250v2
refurb (v1 broke, got a replacement, but it was new when i got it)

firmware upgrades then boots into OFW

is there some refurb pattern? but mine was new when i got it
