Model Number: I9100M
Android Version: 2.3.3
Baseband Version: I9100MUGKG2

Build Number: GINGERBREAD.UGKG2
I followed this guide to ROOT my phone:
I googled "how to root samsung galaxy s2" and the first link was to reviews CNET and that's the one I followed. Sorry I wanted to post the link but I am not able to.
That guide includes doing all the root process with Odin3, loading an unsecure Kernel and then using S2 Root to root the phone.
I went through it all and I'm good. Now the problem that I've been searching an answer for is the following:
I now want to try other ROMs. I went and downloaded ROM Manager. I did the Flash ClockworkMod and the Latest Recovery : ClockworkMod 188.8.131.52
When I click in Backup Current ROM it gives me the input for the name of the backup and I click ok. The phone restarts and goes into the Android System recovery <3e> and I get this
Android system recovery <3e>
Enter: OK Key, Select : Vol UP / Vol Down
reboot system now
applu update from sdcard
wipe data/factory reset
wipe cache partition
-- Installing package...
Finding update package...
Opening update package...
Verifying update package...
E:failed to verify whole-file signature
E:signature verifiaction failed
Then I select reboot system now and it boots to the system. When it boots though now I get a sounds every time it boots, as if maybe something is not valid; so I don't know what it is that is happening here.
I want to back up my ROM so that I could then go ahead and try different ROMs such as the cyanogenmod or the cognition, etc. I am new to this but I do have a bit of background in development (html, php, as2, as3). I like messing around with my phones so I want to see what this Galaxy S2 is capable of.
Thank you in advanced guys.
