SPFlash tool can't flash. Device not booting

[sam27]

I was stuck in a bootloop after flashing AOSP rom. So I decided to power off and use SPFlashTool to flash the stock rom. But both SP and Techno flash tools give the following error:
ERROR : STATUS_BROM_CMD_STARTCMD_FAIL (-1073348607) , MSP ERROE CODE : 0x00.
The phone doesn't respond to any button presses however whenever I connected it with my PC, the charging indicator glows and even windows can detect it, and the device is listed in ports.
Can anyone please help.

TIA.
