Actually I found this site long time ago

but didn't bother to read

taken a look again and found that it works

http://www.xs4all.nl/~itsme/projects/xda/dumprom.html

download his dumprom.exe

follow the instruction and try it on the 8390 rom you downloaded earlier

mkdir dump

dumprom FACHSR42n.bin 0x81a00000 -d dump > info.txt

I could extract the files from the rom

though only 26.9MB out of a 32MB rom image...

And his rapi tools works on 8390 too

reading the readme file...

It seems that you could even use his pmemdump.exe to dump the rom

still haven't figured it out yet

regards

THIS IS NOT TESTED!

Download the tool pack here:

http://www.xs4all.nl/~itsme/projects/xda/tools.html

the binaries are inside of build/

Sign the itsutils.dll with the (gapi solution) code signing pack

then run cmd.exe and goto build/

pmemdump 0x81a00000 0x02000000 mybkuprom.bin

and you get your backup rom :D

thx itsme

haven't tried flashing the rom yet cause i wanna use my phone for the last night

before I screw it up....

but i've checked that the first few kb and last few kb of the file i get from this match with the roms i got earlier.

have fun

Edit:

successfully flash my backup rom back to phone with the flash rom tool downloaded earlier

seems this version of bootloader won't check if your rom is a old one or a upgrade

now I think it'll be more convinent to raw write the image to sd card and flash using the bootloader only, haven't tried this yet
