[Q] Is my device bricked permanently? topic

i got mototola droid razr (xt912)
on boot i get encryption unsuccessful. reset button doesn't seem to work.
in ap fastboot i cannot flash through rsd lite or moto-fastboot flash command or mfastboot flash command.
through fastboot commands i get error: remote.
through rsd lite i get error: phone returned fail.
i have installed proper drivers and have much battery.
rsd lite recognizes phone as fastboot CDMA_SPYDER S
I have tried flashing stock firmwares
2.3.5
2.3.6
4.0
4.1.2
also matt's droid razr utility

Code:

---

Battery OK

XDA please respond this. i cannot mention what ever has been done with that phone.
i heard about linux that linux flashes smoothly stock firmwares instead of windows but cannot find SBF files for my phone.
all links are for zip archived .XML files.

Please solve if anyone got passed through this situation.
Thanks in advance.
