same problem here.
I read nearly all the treads and tried many ways to flash my pharos which is french that comes with default versions. From what I read I understood that I need to install hardSPL because the phone is CID locked. I have windows Vista (not tnat I like it but I have to stick with that because I need licensed software), anyway I understood that there is a problem with flashing on vistas. It always gives me the same error 270. I tried to flash the device with the original rom from htc and it says "invalid vender id". the htc website doesn't even support my phone. they say that my device isn't appropriate for their roms (using my serial number). the only thing that works is the Jump SPL that gives me the grey wallpaper, after starting the flash, the phone goes to bootloader and then starts but as described on other posts it stops on 1% or 2% and reboots to windows. I tryed with uploading .nbh and renamed it to HERMIMG.nbh and some other names to 1GB microSD with fat32 just formated and the bootloader doesn't find it. I don't know if the pharos have some special name like PHARIMG or s.th. like that. I worked here with my imaginations. I tryed on XP and same result. For vista there is some suggestion that it will work by changing the drivers to xp ones but the tread reffers to some other website and the url is not responding so I moved to XP and same result... If someone reads this and have to say something other than rtfm or read the wiki please don't hesitate to help :P
