i thought it was complicated as the first post in this thread... its not.
1. goto htcdev.com unlock your boot loader
2. get clockwork mod 5.0.2.8 from 2fastroms rename to, i know this probably isnt the filename, PH1000.zip (you should see this filename scroll by a few times when you volume down+power on reboot), with the phone on normally move it to the base of the sdcard.
3. Reboot, Volume Down+Power to boot, it should find the ph1000.zip (unless windows named it *.zip.zip or something) and load that clockwork-mod file into the recovery menu of Hboot
4. Reboot and push down and select recovery to make sure it took, when you select recovery it should load the clockwork mod and fire it up for your use.... i kinda didn't know it installed under the recovery menu on HBoot, lol, so i flashed the CWM like 12 times, then chose recovery and boom it was there and realized it was there, i just expected Hboot to look different or something.
4.5 MAKE BACKUP OF PHONE TO SDCARD!!!! (use clockwork mod to do this, its right in the menu)
5. find (via the web), and install su-bin-3.0.3.2-efghi-signed.zip THROUGH recovery menu (vol down+power menu) which is now CLOCKWORK menu, clockwork has a "install from zip file" menu for this....
(you now have superuser installed)
6. REBOOT to normal phone
7. goto play store, install superuser app, then busybox app....super user has to be installed first if not then busybox will say "hey i can't install this, no super user."
8. ok.... this point superuser and busy box should be installed, NOTE: i used smart install when installing busybox, and superuser popped up and asked if i wanted to let busybox install, that verified that superuser installed correctly.
9. REBOOT INTO RECOVERY, make a NEW backup and tack on the end of the filename some-date-here-ROOTED.zip.... I then i used ghost commander to move the original first backup (stock backup) and copied the second (rooted backup) to the fileserver in the basement. so if i screw it up i can find it. i did keep the rooted backup on the phones sdcard for restoring after i tried 2fastroms htc evo designs CyanogenMod10 rom.... it was neat, i liked it alot but there is no 4g (i cant tell) and i am sprint not us cellular (which is what the radio is set for).... BUT i do like CyanogenMod10, lol
soooo, i've spent the day today flashing roms, trying out evo design stuff and RESTORING the rooted back up, cause if you don't then you have to redo steps 5 though 7 each time. lol
