Bootloop even after flashing stock firmware Moto G 3rd Gen(XT1550)



I got an OTA update for marshmallow. At this stage phone was locked, unrooted and not tampered with.
After updating OTA phone went into a bootloop.

'Allow OEM Unlock' is disabled from developer options before even updating OTA so bootloader can't be unlocked.

After bootloop, from bootloader using fastboot (and mfastboot also tried) I flashed "XT1550_OSPREY_RETASIA_DS_2GB_6.0.1_MPI24.107. .... ..." this marshmallow firmware using standard commands for newer Moto devies. Even after flashing firmware, still bootloop happens.


Code:


fastboot flash bootloader O:\MotoG3\Firmwares\bootloader.img
fastboot flash logo O:\MotoG3\Firmwares\logo.bin
fastboot flash boot O:\MotoG3\Firmwares\boot.img
fastboot flash recovery O:\MotoG3\Firmwares\recovery.img
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.0
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.1
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.2
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.3
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.4
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.5
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.6
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.7
fastboot flash modem O:\MotoG3\Firmwares\NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg O:\MotoG3\Firmwares\fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot reboot
pause


At this stage, phone still goes into a bootloop. Clicking on recovery from bootloader also sends phone into a bootloop so can't even access stock recovery.
Also no way to erase system as bootloader is locked.

How do I get the phone back in working state, my device is not in warranty now.
Other bootloop guides were not useful as here even after flashing stock firmware phone still goes into a bootloop. ALso no stock recovery is accessible and BL is locked.

Thanks in advance
