s7800b bricked
« on: May 25, 2014, 12:17:50 pm »
Hi there,

2 months ago i update my jxd s7800b with supercharged 2.2.1 but during this time i had a lot of problems because my jxd had many hard reboots and my save games broke. I decided to change to webclaw and during the restore i had one fail and my jxd never booted again. The error messages was "Download IDB fail"

Anybody knows any method to restore the JXD?


thanx
Regards

Im not sure but I believe that means the boot loader is corrupt.
Im not real sure how to fix that, I think there is a fix however.. I believe you have to short 2 pins on the flash chip inside.. try doing a search someone else had that problem when trying to go backwards from kit-kat to jelly bean.

Finally i booted the JXD. I don't know what was the problem. I've tried with a lot of firmwares to restore the JXD and finally only one of them works correctly and my JXD boot again. After restore from this FW (i don't know what version but i think is the OFW) restored again the webclaw and was succesfully.

i used this link to download the OFW:

Can this ofw be used for s7800b new batch 2014 (rk3188-t) ?
