But please, check that you previous firmware in partitions /dev/tbml8 and /dev/tbml9 is intact.

i begin to study your research now, just i want to inform u that first of doing the procedure on partition 10 and 11 i dont see them on df -h and i do all procedure on 8 and 9, i must restore original images on 8 and 9 first of all?

Oh, so you haven't your previous firmware in partitions /dev/tbml8 and /dev/tbml9 intact now, right? It's a pity for you. If you have backup of it then yes, you must restore it first.

just i want to inform u that first of doing the procedure on partition 10 and 11 i dont see them on df -h

What do you mean exactly by this?

Without these commands, you cannot see those restored partitions with df -h:

Code: Select all

mount -t auto /dev/tbml10 /mtd_exe
mount -t auto /dev/tbml11 /mtd_appdata

Sorry for my question, but do you know what are you doing, or do you just repeat the whole procedure mechanically?

[ji035453]

And yes i'm repeating mechanically some parts of guides, cuz i'm not expert of all of this

So please, look very carefully before you leap.

[ji035453]

Did I understand everything correctly?

This is much better, Exactly .
Please, but check with diff, that your backup of /dev/tbml8 and /dev/tbml9 really contains fw version 2000.5.
At least backup of /dev/tbml8 must contain string "T-CHL7DEUC-2005.0".
PS: What is your native language?
