Root [HOW TO] and some root terminology

[Sailing_Nut]

This got un-sticked? Or is it just me?

Yes it did. The new sticky links it a few times however.

all htc phones utilize a PxxxIMG file system to flash RUUs and such in hboot. having guides up here,the inc,and merge forums, and being active on the board i see alot of folks have trouble getting PxxxIMG(PG05IMG in case of the TB) to work. the prollem usually has simple fix,but sometimes causes folks an extreme amount of confusion.

but there is an easier way

i mess with my various htc devices alot,and have found using fastboot is a much faster,easier way to flash PxxxIMG files. you dont need to transfer files to your SD,or boot to change files if youve got a couple to do.

in a nutshell,youre going to place your file into the folder where adb and fastboot live(prolly platform tools or tools if youre an advanced user that has the sdk installed),place the phone in fastboot,put it in RUU mode and flash the file with this command: fastboot flash zip <filename>.zip

if you rooted with revolutionary,and have no idea what fastboot or adb even are,heres a step by step:

1)set up adb and fastboot download this file,wich contains adb and fastboot.

extract it,and place the extracted(not zipped) mini-adb folder on the root of the C drive of your PC. in windows 7,you should be able to just right click,then extract files. if not,you may need a utility such as 7 zip

re-install revolutionarys drivers,if you dont still have them on your PC from when you rooted.

open a command window. in windows 7,just click the start bubble,then type "command" in the search box. this should open a small black window.

change to your mini-adb directory(folder) by the entering the following command at the prompt in your command window: cd c:\mini-adb this should change your prompt to "mini-adb>" indicating that youve changed to that directory.

2)flash your file put the file that you want to flash into the mini adb-folder. you can copy/paste,drag/drop or move it however you are comfortable moving files.

plug in your phone. enable usb debugging,if its not allready.

enter the following commands. from here on,commands will be bold and italics,comments will be blue. each line is one command,enter them one at a time. you can copy/paste or type them in.

md5sums <filename> this will output the md5 sum of the file you will flash. make sure it matches that listed for your download

adb devices should output your phones serial number

adb reboot bootloader will boot you into the fastboot screen(white with colored letters)

fastboot devices will again output serial number

fastboot erase cache

fastboot oem rebootRUU

fastboot flash zip <filename>.zip

you will see a green line on your phone as the file flashes.youll see outut in your cmd window. sometimes when flashing a complete RUU you will get an error that says "failed,reflush immediately". dont panic,just run the above line again to reflash your file

after you get a "finished" message:

at this point,ycould actually flashe more files if you wanted. for example,a radio and a recovery. just repeat the "fastboot flash zip" command untill youve flashed all your files. then:

fastboot reboot-bootloader this will take you back to the white fastboot screen

fastboot reboot your phone should reboot

and of course,heres what the outputs will look like in the command window. red are my inputs. in this example,im installing twrp recovery,with a .zip file called: twrp111rbox1_PG05IMG

seems a lil complicated,but once you do it a couple times,its quick and easy.
