Help please I have searched but its still dead

[setter]

Hi I have loaded 6.5 on my hermes
It worked great till I put a SIM card in whereupon it froze in the 6.5 screen and goes no further.
I can get it into bootloader screen but it wont load a new rom or anything much else - when you put a new rom in renamed hermimg.nbh it reads it for 30 secs and goes back to the bootloader
Active synch doesnt recognise it with usb turned on or off
Please advise what Im doing wrong?
Kind regards
John

Have you tried taking the SIM out and then approaching the reflashing process?

Hi
Yes I took the SIM card out and tried it again - no help
It starts to reflash - then stops and boots back into the start up screen and locks up again

still trying lots of things from here but no luck yet- Any thoughts?
Kind regards
John
