first thing you need is drivers for adb to see your phone. if you have htc sync installed,you should allready have drivers. if not,you can install htc sync,or install these modified htc drivers from revolutionary

most guides simply say "follow the directions to unlock with htcdev" but im gonna go thru it with ya the mini-adb.zip file is all the files that htcdev is telling you to download and put into a folder,so allready this should be a lil easier

1)prepair ADB
-unzip your mini-adb.zip file. this is native funtionality in windows 7. you otherwise may need a utility such as "7-zip" to extract,or unzip it. place the unzipped folder onto the root of your C drive on your PC(sorry, you mac guys will need to develop this for yourself,i dont have a mac). root means the top level,not inside any folders. so just copy and paste,or drag and drop the folder onto C with everything else that is there. you may want to rename it to "mini-adb_devicename" since youll be putting some device specific files in here. (directions from here forward will assume this folder to be named "mini-adb_vigor",as an example)
-open a command window. on windows 7,click the start bubble in the lower left and type "command" in the search box. xp i believe is similar or the same. doing this should open a small black command window.
-change to your mini-adb_vigor directory. type the following at the prompt in your cmd window:

cd c:\mini-adb_vigor

your command promt should change to "c:mini-adb_vigor>" provided you: 1)unzipped the miniadb zip 2)put the folder on your c drive 3)entered the name of the folder correctly ("mini-adb_vigor" in this case)

-now make sure usb debugging is checked in settings/apps/development,and plug your phone into your PC with a usb cable
-make sure your phone is being recognized- type:

adb devices

if your drivers are installed correctly,this should return your phones serial number. you should hear the "found device" noises when you plug your phone in. if it starts installing drivers,wait for it to finish before typing the adb devices command.

2)unlock using htcdev
-go to HTCdev - Unlock Bootloader and sign in to your account. chose your device from the "select your device bar"(or "other supported devices" if its not listed) and click the green "begin unlock bootloader" button underneath.
-click yes to procede,then read the warnings before checking the boxes and clicking yes to continue,as they are basically explaining that your warranty is now void,and any repairs that your phone needs that may have been a result of unlocking your bootloader and messing with your phones operating system may no longer be covered under mfgr warranty

*check your hboot screen. if you allready have an htc compatible hboot, then skip ahead to the next step,you dont need this.if you have a pink **locked** at the top of the hboot screen,then it is compatible with htcdev. if you dont have a compatible hboot,then download the RUU for the new hboot. right click it,and run as administrator. plug in your phone when prompted to. it will ugrade your hboot to the htcdev unlock compatible version.

-steps 1-4 are describing how to get your phone into bootloader mode and connect it to your PC,wich we have done above. ignore these steps and simply type in your cmd window:

adb reboot bootloader

it may take several seconds,but this command should boot your phone into the "fastboot" screen wich is white with a bunch of colored writing. once this happens,make sure your phone is still being seen in fastboot. type:

fastboot devices

again,this should return your phones serial number.

-click the green procede to step 5 bubble.
-steps 5-7 are telling you how to find the files and utilities inside your mini-adb folder. you have them,so ignore steps 5-7.
-click the green procede to step 8 bubble.
-heres where steps are important,steps 8-10 are telling you how to get your unlock token,and send it to htc. its phone specific(so they prolly know your serial number,meid,etc) so no,you cant use your buddys unlock token and not have htc know that youve unlocked your bootloader. copy this line either from below,or from step 8,and paste it into the prompt in your cmd window. you have to right click to paste in cmd,you cannot control/v :

fastboot oem get_identifier_token

-after yuo hit enter,you will get a bunch of letters that are your identifier token. not much i can say,other than follow the directions in steps 9 and 10 to copy and submit your identifier token to HTC. make sure you get the characters as shown in the pic,with no extra lines or letters. note that you can also hit the "enter" key on your PC to copy,as well as right clicking.
-click the green submit button. wait patiently for an email containing your unlock code. (dont worry,it should come pretty fast )
-save the unlock_code.bin that htc sends you directly to your mini-adb folder(if your PC automatically downloads somewhere else,no biggie. just move the unlock code to mini-adb folder)
-click the link in your email to get the rest of the unlock instructions
-step 12 is where them magic happens copy from below,or from htc dev:

fastboot flash unlocktoken Unlock_code.bin

-youll see the purdy screen pictured in step 13. use the vol rocker to chose "yes unlock bootloader" and select it with the power button. your phone will reboot,performaing a factory data reset in the process. your data is gone,sorry this boot may take a bit longer than they normally do,dont freak out this is normal

as you can see,once the adb files are put in one place to download,its not hard to use,and the commands are pretty simple. below is what you will see in your command window,the red are my inputs.

if you want to run stock,do not permanently install your recovery. keeping the stock recovery on the phone will ensure that you recieve OTAs without a hitch,wich i know is important to alot of users. YES,the OTA will break root. its no big deal. one good thing about htcdev is that you will always be able to reroot after,simply by following steps 2 and 3 again to launch recovery,flash superser.

once youve either skipped past all the setup,or have re-set up and are ready to root,chose either of the following options to either permantly or termporarily install a recovery:

1)temporary recovery:


2)permanently install your recovery

there is not much to explain with this one. if booted to recovery from above,use the recovery menu on your phone to:
-make a backup of your stock,unrooted rom. completely optional,but a very good idea,IMO.
-wipe cache
-wipe dalvik cache
-install zip from sd card(chose your superuser file)
-reboot

*congratulations,youre rooted
