Root Bricked htc evo view 4g (htc flyer)

[Medkid]

Hi,
I'm stuck in this situation with my htc evo view 4g device. I think it's a kind of soft brick, It still boots in to fastboot mode,and I could see that it's s-on, hboot is 1.13.

everytime I try to reboot, or enter recovery, or factory reset it just hangs at this screen:

I try to flash this stock rom
RUU_Express_Sprint_WWE_1.22.651.1_Radio_1.05.11.0531_NV_2.28_SPCS_release_198141_signed
(via both RUU on my pc and goldcard with PG41IMG.zip), it was flashed flawlessly, but when finished it hangs in that "htc" screen.
I tried to s-off by revolutionary but I can not access the android working screen so that can not enable usb debugging mode, on the pc it just shows

waiting for device ....

I tried to unlock the bootloader via htcdev (I know my view 4g isn't in the supported list yet, but at least fastboot should read its info, but I was wrong). At step 8, it shows:

C:\Android>fastboot oem get_identifier_token
...
(bootloader) [ERR] Command error !!!
OKAY [ 0.007s]
finished. total time: 0.007s

Can some one please help me with this ?
Thanks a lot,
Medkid

Is there a chance you flashed Flyer ROM instead of View ROM?
Where did you get this ROM?
Is it under warranty?
