MTD Partition problem
« on: February 28, 2013, 07:28:05 PM »
Hi again,

Having sorted out mu bricked S5100 , i now have another problem.

Can now boot into Recovery by pressing Power+Menu , i can to "Apply update from sdcard"
This gets 1/4 way thru when it throws up the following errors:---

E:failed to find "cache" partition to mount at "/cache"

----wiping data...
E:format_volume: no MTD partition "userdata"
Formatting /cache....
E:format_volume: no MTD partition "cache"
Data wipe complete.
E:failed to find "cache" partition to mount at "/cache"
E:can't mount  /cache/recovery/log
E:cant open /cache/recovery/log
E:failed to find "cache" partition to mount at "/cache"

tried wipe/factory wipe etc.

Prob something simple to fix but spent ages fixing the brick problem now this....

Any help would be great , as im beginning to lose faith in this machine..

thanks

It seems nand memory is corrupt. Try to make a Wipe Media partition to see if it helps, then wipe data, and cache.

You can try with the CWM for the s5100:

http://forum.openhandhelds.net/index.php/topic,311.0.html

Just put uImage_recovery in root of sdcard and boot with power and menu. Then try to format the emmc partition to see if it helps.

Also, the skelroms for s5100 also come with a full format of the device.

good luck, it's my last bullet.

Thanks for ur help m8.

Bit weird thou, tried everything i could think off and stuff you said.
Then thought maybe a dry joint, so took it apart , heated nand chip up a little after put flux on it .

Re soldered battery as it was a little weird looking on mb connection.

Then put it back together.
Seems to now work but when i installed a Update zip it always gives a Offset error.

Is this ok ?

Seems to work but after a while will randomly turn off.

Again thanks for ur help.

It seems the nand was corrupt, or probably device has serious problem of overheating, which provoked that. Goog to know you solved it.
