your phone is stuck in ruu mode.

do you have the android sdk set up?

if so,plug in the phone,open a cmd window,make sure the phone is beeing seen:

fastboot devices

if you get your serial number back,then

fastboot reboot-bootloader

however,that will not necessarily fix whatever is wrong. you can try extracting "rom.zip" from the ruu,and flashing it in hboot. but it will likely hang on whatever partition its hanging on when running the ruu.

unfortunately,hanging on any partition is not good sign- especially if its the radio or other firmware.

let me know if you need more specific directions

Can you post the output of:

Fastboot oem ?

 

[scotty85]

sorry for the short answer earlier, i was at work

when you enter "fastboot oem ?" it should spit out a bunch of different commands. the one youre looking for is this:
INFOresetRUUflag

if you see it,youll want to put the phone in fastboot,open a cmd window,then enter:
fastboot devices

fastboot oem resetRUUflag

fastboot reboot-bootloader

that should get you back to normal fastboot some older hboots do trap you in ruu mode if something fails,sorry for the confusion.

to answer the other question,the sdk is the android "standard development kit" wich contains utilities such as adb and fastboot. since you knew how to open a cmd window and run the command,i assume you have something set up containing those utilities... even if you were calling it somethign esle
