Herald wont turn on, only bootloader mode

[os_man]

my phone is hard spled. things went fine after hard spl, i was able to flash 2 roms, the last one was juststablev2. after one day my phone started to freeze, random crashes, finishing with a "white screen" and then resets. and after a couple of crashes the phone coulnt even load windows anymore, after the splash screen it continiued to reset. and now, the phone dosnt gets on anymore, it only goes to bootloader (not when you turn on the phone, it cant be turned on, only pressing cam button and resetting turns the phone on and you can only be in bootlader. ) i tried everything, readed almost everything in xdadevelopers, tried to flash with shipped roms, tried to flash with custom roms, tried to flash from pc, to flash from sd card (and yes i know everything to do becouse i did my earlier flashed with sd card, all went without any problem). it just looks the phone is dead, but can enter into bootloader. do anyone have any idea ? ill be realy very thankfull if someone can think something about my problem.

ps : my SPL is 4.70.yang

You can't flash your carrier ROM from bootloader mode via USB?

No, i can not. i forgot to mention that every rom install attempt is turning back with the error 244 : invalid model id.. Just one time, i did get a message, when i was trying flash with the juststablev2, it gave me an error about certificate. but not the same sd card, same rom, gives me nothing, just goes to bootloader mode after checking the sd card.
