I figured I would clear up somethings from my post last night. Originally I had rolled all the way back to pre-nodo to unlock and was really over doing everything.
After unlocking mango on my phone that way I decided to try my girls hd7 by just adding custclear.provxml to the windows directory on nodo while unlocked.
So here the updated step by step. So far its only working on HTC devices.
1. Make sure that you have nodo unlocked and download the latest HTC Connection setup from the MARKETPLACE.
2. Place the CustClear.provxml from this post in the windows directory on the phone. There is a number of ways to do this. I used Windows Phone Device Manager but you could also use the Chevron Ringtone App to get it to the phone and TouchXplorer to move to the windows directory. Or Remote Suite, etc. Included in the provxml is developer unlock, max apps, and prevent relock.
3. Update to mango.
4. As soon as mango starts run HTC Connection setup. And your unlocked.
Ive had mine unlocked since last night and hasnt relocked itself. Ive synced with zune several times, Sideloaded over 10 xaps and everything is going great.
So thats the short version of it. Had a good feeling it would work without going all the way back to pre-nodo. So if youve already upgraded to mango you can just restore your unlocked nodo and restart.
Im glad I got to help out the community. Im in no way a genius when it comes to this stuff though I wouldnt say Im in the dark. Just put the old regedit trick to work.
