I have spent hours on xda, downloading gfree, trying to downgrade, trying taco root. I even unlocked bootloader at htc dev and cannot get my phone perm rooted

I have 2.3.4
software 2.32.531.1

i used the guide on how to downgrade to 2.2.1 for the visionary exploit

i keep getting permission denied
Potential exploit area found at address fbb80e00:200.

I am sorry for sounding like "noob" but i wasted the day trying to do this and have given up

Someone please help me, ill even donate a cup of coffee to whoever helps me fix this. No joke from 9 am to 530 pm, i have been going in circles, i downloaded the htc easy root tool all failed

the farthest i made it was getting temp root with taco root, but there are no clear cut instructions for what to do after, these guides are over a year old prior to my version of android

I'm not sure where your going wrong but the guides work fine. I used them to downgrade, perm root, and flash the engineering bootloader. Have you tried asking in the q and a section? I'm sure you will find a solution, if you ask in the proper place.

cnote 74 i tried that guide my expolit area "fbb80e00:200" is not covered by that guide, if you look at the 5 or 6 lines

$ /data/local/tmp/fre3vo -debug -start 10000000 -end 1FFFFFFF
$ /data/local/tmp/fre3vo -debug -start 20000000 -end 2FFFFFFF
$ /data/local/tmp/fre3vo -debug -start 30000000 -end 3FFFFFFF
$ /data/local/tmp/fre3vo -debug -start F0000000 -end FFFFFFFF
$ /data/local/tmp/fre3vo -debug -start E0000000 -end EFFFFFFF

2nd....its because you unlocked via htcdev, which we have warned users multiple times if you did read the Q&A and General forums.
Htcdev method makes it harder to root/flash a ROM. We warned you. And then you complain and post in the wrong section!
Edit: also.....If you knew to put "DON'T MOVE THREAD", why did you post it here in the first place?
