I think you need to right click on the revolutionary.exe and extract it. Then try running it again.

Unknownforce, you have some major balls developing this. Thank you, am getting all the files ready to give it a shot. Major kudos to you man.

EDIT: Two minor things I think would be helpful to add to your guide. 1. The AC power source does matter. I tried with a generic charger at first and for some reason it didn't work. The device lost power. I used the htc charger and it stayed powered on. 2. since I have a class 10 card, it reads the zip file quicker, so instead of 5-6 seconds its only about 2-3 for me. r/w speed is an important factor. Hopefully this isn't seen as nitpicky, I just want people to avoid having issues. Thanks again.

If I'm on 2.17 do I just need to use the 2.17 ruu instead of 2.08 and follow the same steps?

Successfully downgraded and took the PG86IMG off the SD card. When I reboot the phone it is in a bootloop. What do I need to flash now to get me out of the bootloop so I can take care of getting s-off?

Thanks.

The reason for #1 is that HTC's chargers charge at a higher rate, this is also the reason it wouldn't work through a USB connection to a PC. USB max is 500 mAh, HTC charger is 1000 mAH, the generic ones or other brands, are 900 mAh, it needs the full juice to stay on. But you could also do this via pulling the battery at the right time as well.

As for #2, the speed of the SD Card only matters for the initial copy to the device, which happens before you're updating, the zip file is copied to the device and flashed from the device. So the sd card speed does not matter for the bricking process. Found this out by pulling the SD Card out right when it says press vol up to flash, then press vol up, it still flashes.

This is normal, you have to run the RUU exe for 1.13, then it will boot normally.
