Hello
i bought HTC HD7 yesterday and now i want to unlock it with ChevronWP7 so that i can install sideload apps from pc
but i have 7392.0 os version and ChevronWP7 cant unlock Nodo
so my question is how can i downgrade from 7392 to 7004 original rom and then again upgrade to 7392?
what rom then i need to install i am from Croatia (europe) ?
OS: 7.0.7392.0
firmware: 2250.09.16901.401
Bootloader:4.5.2250.0(192185)

Thank you

all Shipped ROMs are available here.
or you could just flash a Custom ROM, which is already Dev Unlocked, or better, here.

For custom roms I need to install hspl? Shipped roms I can install with original spl?i heard that you can easily brick phone by install custom roms and hspl,is that true?

yes, Shipped ROM can be flashed with OSPL, as long as the vendor id's match.
phone can be half bricked if you try and flash RSPL/HSPL onto an unsupported SPL, yes.
if you want to go the Custom ROM route, i would...
01) flash a stock Shipped NoDo or Pre-NoDo ROM.
02) flash RSPL or HSPL.
03) flash Custom ROM with task 29.
04) flash desired Radio with task 00, if desired.

well, if the vendor id's don't match, the flash will fail.
ie. flashing a TMOUS ROM onto a HD7 T9292 will fail, etc.

RSPL is a temporary SPL which will return to OSPL after reset.
HSPL isn't temporary.
both allow one to flash Custom ROMs.
