My lava 504q was bricked so i was using above method for unbricking it step by step, but got following error after connecting the phone,
"Image PRELOADER checksum failed!Checksum reference value(0x2f771) in the config ini file.
please re-fill correct checksum values in checksum.INI under tool folder and re-load scatter file again!"
Same error also include Image like UBOOT, BOOTIMG,Recovery, LOGO, ANDROID, CACHE, USRDATA and FAT
I used unbricking method on Windows 7 and Windows 8.1 desktop.
Right now i am in deep trouble and you guys are my last hope.
So please please help me.
Thanks in advance
Delete checksum file in that folder.. And then try.. It will work.
