RE: Restoring stock firmware on EPC2100r2
how corrupt is your backup? i'd try extracting the nonvol from it amd inserting it into the dump you downloaded that way you'd have a working stock dump
this is a gif showing how to extract a nonvol http://www.haxorware.com/forums/thread-9...ml#pid5188
so for you to make a working dump the commands would be (using sbh_usbjtag in 510x mode or toms)
ldram 9fc00000 (select your nonworking backup)
save cfg (you can check the cfg tab to make sure the nonvol looks correct like i did)
ldram 9fc00000 (select the working downloaded dump)
ldram cfg (select the nonvol you saved)
save 9fc00000 200000 (this should save you a correct working dump)

RE: Restoring stock firmware on EPC2100r2
Dear drewmerc,
Thanks a lot mate for your guide. Did it this morning and it works like a charm. Thanks again for your help.
I don't know how corrupt it is, or what is corrupted, at which level. As we see now extracted nonvol works. I also extracted the bootloader and compared it with the working firmware. Only first two bytes differ, all the rest is exactly the same. Maybe that is the cause, or something in the firmware. When i created backup, if i remember correctly, i did a full save 9fc00000 200000. It is what it is. Anyways, working beautifully now. Thanks my friend!
