Help [HELP] May Have Bricked When Flashing

[Carwyn]

Ok, run down;

I rooted my SGII, CWM was working.
I got RomManager Pro, I followed the instructions to install CyanogenMod.

I got the error:

"E:failed to verify whole-file signature
E:signature verification failed
Installation aborted"

I couldn't find a good suggestion about what to do, some people suggested flashing and going the wipe route.

I followed the instructions here; http://forum.xda-developers.com/show....php?t=1176411 telling me to;

"Harder way:

Make sure you're running a rooted device.
Root your device and install ClockworkMod Recovery (http://forum.xda-developers.com/show....php?t=1118693)
Do a Nandroid backup!
WIPE (wipe data/factory reset + wipe cache partition) - do it for real.
Install the ROM from internal sdcard using ClockworkMod Recovery
Optionally install the Google Addon (through ROMManager is easiest)"

After I installed the rom .zip file I restarted and I am stuck on the Samsung Galaxy SII GT-19100 screen with the yellow triangle and exclamation mark.

Any suggestions would be extremely welcome. Kind of freaking out.

Firstly, no need to panic. If there's any sign of life then it's not a "brick".

Pull the battery, then reboot into recovery and try reflashing the CM7 zip file again (without wiping this time). Sometimes only the CM kernel is installed first time around.... happened to me and the symptom is exactly as you describe.
