Hi Guys,

Android Version : 2.3.6
Kernel Version : 2.6.32.9-gbdd614e

Problem :
When i try i install any custom roms, i am getting boot loader err. But i was successful in installing CM7 but i am unable unable to install other custom roms.
Actually the roms gets installed but when i try to boot for the first time i always get bootloader error.

Did u Flash Kernel?
make fixed SBF From Ur Stock SBF.(moto andriod depacker-Delet CG31 And CG39)
and flash Fixed SBF With RsdLite.

Yes, it looks like sbf mismatch. See this guide for defy+. You can also try to flash a nandroid backup like this one

Thanks for your help guys, but i understand very little.
I have a nandroid backup, whenever i get bootloader error,i usually flash a Stock SBF then i will restore my phone using the nandroid backup.

Can you guys guide me how to install CM9 on my defy plus.
I flashed CM9 rom and i have also flashed CM9 kernel for gb but i am still getting bootloader error. Where i have went wrong

What is mean by SBF mismatch??

flash stock SBF.
Root
flash CM9 For DEFY+ .
DONT FLASH ANY KERNEL.

Just follow this instructions carefully. Common mistake is that you forget to wipe cache and data. So, wipe cache and data, and reboot. First boot takes longer (about 10 minutes). Good luck.
