Unable to flash S620 with signed .nb0 file

[AlexeyGee]

Hello guys!

I've got S620 unlocked by imei-check.co.uk. Currently with official HTC WM6 English rom onboard.

I have a signed .nb0 file (49mb).

Trying to flash -> get multiply errors.

I press 'camera' button, connect USB cable. USB is disabled in activesync.

MTTY screen is the following:

Cmd>set 32
+ SD Controller init

- SD Controller init

---------------------

It seems i should enter 'right' bootloader start address after "lnbs flash.nb0" command - any clues, how to find it?

And one more question: why when i enter "lnbms" command i receive unknown command in return?

Thanks,
Alexey
