Because im stuck at the htc logo and can't get into recovery i thought downgrading would help me flash it with unrevoked,i cant get unrevoked to recognize the phone because i can't turn on usb debugging.

[Q] post s-off H-Boot issues

I have this strange problem.
I did the s-off using the alpharev. Once that was done, I experienced random reboots and phone lockups.
So, I decided to revert back and used the 2.29.405.2 ruu to get back to stock htc image.
Now, I am unable to root my desire using un-revoked. The phone freezes after doing the hboot and pre-boot sequence. I tried downgrading my hboot and I continue to experience the same problem.
Is there a way to get the phone to factory conditions ? I use a MAC. Can I use the RUU exe instead of the PB99IMG.zip ?
Has anyone faced a similar problem before ?
Any leads/pointers would be appreciated.
And yes, I am not a newbie and can find me way out through the adb forests !
Thanks

bootloader should not change things about rooting.
have u checked hboot what does it tell now?
Thread moved to Q&A.
0.93.0001 S-ON is the hboot version that I get.
RUUs are Windows applications. You could just get the 2.29.405.5 PB99IMG and flash that to go back to the latest stock ROM
I am unable to root the stock 2.29.405.2 using unrevoked too !! The phone freezes after doing the pre-boot sequence.

Are you using the current version of unrevoked or just some old version you found on your harddisk? Older versions could not root froyo based roms.
€: Perhaps they also patched something in 2.29.405.2 that prevents this rooting method.
I've had no issues with 2.29.405.2 using unrEVOked 3.22 - not tried since going back to 2.29.405.5

Desire HD bootloop

Hello everyone ,
So here's my problem, I have a Desire HD, no root and bootloader locked, the problem is that my HTC doens't turn on, it's stuck on the HTC logo screen. I have tried nearly all the possible solutions before opening this thread; the Hboot, Fastboot and default recovery are working just fine which means it's probably an Android software problem. I tried to use the official RUU, didn't work, tried to unlock the bootloader with HTCdev to flash a custom recovery, didn't work since i have to update the Hboot and can't use the RUU. Anyone has any possible solution to this problem?
