I would probably give a full backup a try before doing anything - using Paul's scatter file in his downloads section I'll probably try this when I get time:
You should be able to make a backup of everything - boot.img recovery.img etc and be able to flash everything back.
I have another Mediatek device I'm playing with and if anyone has any tips on creating a scatter file for mediatek devices any advice is welcome!
Tried ! but /proc/mtd is empty !
I also found one of your post about G500 and the Gallant also use /proc/emmc instead as below :
partno: start_sect nr_sects partition_name
emmc_p1: 00000020 00000002 "ebr1"
emmc_p2: 0010f720 00100000 "cache"
emmc_p3: 0020ff20 00200000 "usrdata"
emmc_p4: 00410720 003328e0 "fat"
emmc_p5: 00009f00 00002800 "sec_ro"
emmc_p6: 0000ef20 00100000 "android"
The Mediatek engineers mode also works for this phone
