Default Unable to Flash Custom Recovery (TWRP 1.1.1,)

I have an EVO 4G phone that I am trying to root. It has hboot 2.18 and I followed some instructions for that hboot. I used the htc unlock bootloader and it is now unlocked.

I trying to follow this procedure from teramrevolation: http://teamrevolation.forumotion.com...ing+hboot+2+18

I am running into difficulty when I get to where I flash a custom recovery. I have put a custom unloader zip file on my SD card. When I enter: adb reboot bootloader the phone turns off and the bootloader opens. I then select boot and that changes the menu to include recovery and I then select recovery. The phone reboots and I get a triangle and an exclamation mark. I then press the volume up and power buttons to get the android system recovery <3e>. I have the followin options listed:

Reboot system now
Apply update from sdcard
Wipe data/factory reset
Wipe cache partition

Also lower on the screen in yellow text it says: E:Can't open /cache/recovery/command

If I select "Apply update from sdcard" and press the power button it doesn't install the update it gives the following message and reboots:

Invalid operation

Success rebooting by reason: oem-00...

I looked around in some forums for the message above and there was a suggestion to enter the following commands, but, doesn't explain what to do with them:

adb reboot bootloader
fastboot devices => which returns HT0A3HL06966 fastboot
fastboot getvar cid => which returns cid: SPCS_001

I take it getting the cid is important, but, I don't know what to do with it???

Place the recovery file on the root of your SD card. Rename it PC36IMG.zip (make sure you don't have an extra .zip extension on the end of the file name). Reboot to the bootloader. You should be prompted to update afterwards.

That is what I did. It is named PC36IMG.zip. I did a MD5 check after I copied it to the SD card.

Did you select the bootloader option from the bootloader menu?

You can also push the recovery to your phone via fastboot. Just put the recovery image file in your ADB/Fastboot tools folder and connect via fastboot USB. Use the command "fastboot flash recovery nameofrecovery.img" to push it to your phone. Also, you don't need to worry about CID with this device, and, further, the menu you're referring to is the stock Android recovery menu.

Yes, I did select bootloader.

I'm trying the fastboot flash recovery method now. It seems to have started, there are now error messages after I enter fastboot flash recovery openrecovery_supersonic.img, but, all I see is <waiting for device>. It has been waiting for over thirty minutes.

I may take another approach. My phone is unlocked, but, not s-off. I think I will try this method http://forum.xda-developers.com/show....php?t=1771755, starting at step 21 as I've already performed the prior steps.

If I can get it fully rooted with s-off I think I can then install install recoverx, or oneclickroot right from google play store.

Any thoughts?

My EVO is unlocked but S-ON. It;s rooted and had CWM Touch 5.8.0.1 recovery already installed.

I just installed TWRP 2.63 using the fastboot method on a Windows XP computer. do you have the HTC drivers installed? When you boot into the bootloader, then plug your phone into the computer via USB cable, the Bootloader status should change to Fastboot USB.

ran the fastboot flash_image recovery command in it transferred pretty quickly.
