somebody help me.... encryption occured and now phone won't flash anymore..

I need help regarding my Zen ultraphone 502. I had problem encryption unsucessful screen everytime i reebot and I cannot pass through it the phone kept on that screen even the reset button didn't worked.
So I decided to flash my phone with ultraphone 502 official stocked image jelly bean with sp flash tool.
After the tool proceeded i got stuck at error:
BROM ERROR : S_DA_SDMMC_WRITE_FAILED (3149)

Hint is blankl.

The phone is dead. I cannot start the phone but the phone is detected in sp flash tool and windows os. I think it is bricked.

Can do a full format. Can also do memory check... But am not able to flash a single file.. Now my phone is dead it won't boot up..

So any help ASAP would be appreciated.

Plzz plzzz i need ur help..

Thanks!!

There is no problem with the rom ... Am using stock rom and had flashed it so many times before...

Any way to solve this problem..
