BL unlock needed!
This is kind of useless, untill we get bootloader unlock. I've managed to build recovery.img for MT6575 chipset with some tools and also flashed it to E440, but bootloader is blocking the recovery boot due to security reasons, but boots in normal mode(Android)... i can share recovery.img if someone need it.
Update: I have boot.img and bootloader image, too - everithing except /system and /data
Added: Ops... My bad. now I think it is kernel related security check, will take a look at the kernel source and try again. I'm not a DEV, just playing.
