don't flash it like a rom or kernel... rename to PC36IMG.zip, place on sd card, reboot in bootloader... when it finds the file, select ok to update...

Directions I used successfully:

Try the kernels first. Your phone may just not like the current kernel. Try all three Freedom kernels, your phone may like one of them. Only downgrade if you don't have another choice.

If you want to skip straight to the downgrade here you go:

You need to download the .zip files from xda for the nv and pri version you are trying to run. I would try the 1.77 version of both the nv and pri.

[ Radios ][ 9-5 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions - xda-developers

download the files and put them on the root of your sd card.
boot into recovery and full nandroid
Wipe dalvik and cache partition multiple times
Flash either the nv or pri, ONE AT A TIME!!
flash one, then reboot, BE PATIENT!!! Do not pull the battery!!
Boot back into recovery, wipe caches again, flash the other, reboot.
Be patient again!!
I haven't heard of any bricking with pri or nv flashes, but I would treat them like radios, with kid gloves.

Remember you flash these at your risk, ask questions if your unsure before you flash and bork something.
I flashed these back when I was an uber noob, plus I'm completely illiterate.....well thats not true, but you get where I'm going with this.

Rxpert83 you beat me to it. but i'm curious op why are you downgarding pri? and which one? and you do flash it in recovery. there was some files floating around for the gingerbread radios that were in PC36IMG form, but the radios in the rom/kernel sticky you have to flash from recovery.

I told him to try kernels first, and if the excessive drain continued try a pri downgrade.
The steps I listed are exactly how I did mine a few months back.
