Boot to fastboot holding the back button while you power on your phone. Connect phone to computer an run the RUU update.
If your device is branded you will have to use a RUU matching your operator.

UPDATE I trayed your rom and its says Error 170 usb failure.. is it becouse of not Vodafone rom?

No, it's an error on the USB Connection...
well its says FASTBOOT. As soon as I connected USB from pc its says FASTBOOT USB so usb might work.

Tried turning off any antivirus/firewall?
Do you have htc sync installed? If not, try installing it.

Hello Mikep I installed htc sync disabled firewall and anti virus.. HTC sync after i connected phone wont find phone it says no device connected, bu when i pugged that cable to phone and pc windows says HTS device driver installer corectly ...
Have you tried now running the RUU with antivirus/firewall off?
Basically, disconnect phone, boot into fastboot (power & back key), plug phone into PC. It should now show FASTBOOT USB or similar.
Then try the RUU.

htc desire 816w briqued ! plz plz help

Hello geeks,
here I have bricked my phone fault false manipulation, I end up with the HTC logo loop !!!!!!!!!!
I have no Access to bootlaoder with low volume + power
by cons when I made ​​up volume + power I can access the recovery <3e>
I can not flashing the bootloader or install a new rom since my recovery are not a custom so do not let the file not sign
you can flash a recovery from a third recovery via SD card?
Another prob;
when I try to do (apply apdate from ADB) my laptop does not detect my phone driver, sometimes I have ADB android interface, sometimes htc dream !!!
I install HTC driver, htc sync, adb driver, 68xx prelooderdriver SDK manager.

Help!!! Flashing HTC desire eye 910x cant be done

Guys
I have tried all the mentioned ways in this site to flash my system but i am no where..
My issue starts with unlocking bootloader, when ever i try to unlock it using windroid or cmd commands or htc dev the phone reboots to a black screen and at the bottom says fastboot mode and just stucks there for a while till cmd says faild to get keys or something like it ..
And the phone keeps it at that screen until i power it down, i have all the drivers installed the right way and adb drivers as will and cant get the phone to unlock bootloader.
Any solutions please..
Hello moh.naser. Have you tried doing thjs from the official Htcdev site ? Because all information about doing this are listed there in 6 steps..As you mentioned you have installed all drivers with the appropriate way,but check again 1st if your device is compatible 2nd if you wrote the token right and 3rd if you pressed the yes option to unlock the bootloader..Pls let me know
