I have software build 2.36.605.1, and none of the ROMs I've been able to find have worked for rooting my Eris...
What is happening when a ROM fails? At what point do you see that it is not working?
I am wondering if you've followed the rooting guide (all steps, including "prerequisites"), especially, from

II. Installing Amon's recovery image
1. Download this file:
Recovery.zip
2. Extract file contents to your \tools\ directory of your Android SDK.
3. Open up a command prompt and go to your tools directory, and execute these commands: (MAKE SURE YOUR SDCARD IS NOT MOUNTED TO YOUR COMPUTER OR THESE COMMANDS WON'T WORK! MAKE SURE IT IS ON "CHARGE ONLY")
- adb shell mount -o rw,remount /dev/block/mtdblock3 /system
- adb push recovery.img /sdcard
- adb push flash_image /system/bin
- adb shell chmod 755 /system/bin/flash_image
- adb shell flash_image recovery /sdcard/recovery.img
4. Success! You now have a recovery partition installed on your phone. You can access it by running "adb shell reboot recovery" or by powering off your phone, holding "Volume Up + Power On"
..and the, and
only then:
III. Installing the new rooted ROM
1. Download the rom here:
eris21official-root.zip
2. Place the file eris21official-root.zip on the root of your sdcard
3. Reboot your phone into recovery mode.
4. Go to Wipe, and do a wipe of data/factory reset, as well as dalvik-cache wipe.
5. Go back to the main menu and select "Flash Zip from SDcard"
6. You should see eris21official-root.zip. Select it. Press the trackball to flash it.
7. That's it! You're now running the latest version of the root rom. You will use the same process in this section most likely to flash future updates to the root rom, so remember how to do this method with the recovery partition.
From that point begins the fun of finding a ROM you like, not one that will flash successfully, because just about any ROM out there will flash successfully if you've carefully followed those steps from the guide.
