Hello, I have a Samsung Galaxy S2.

Model Number: I9100M
Android Version: 2.3.3
Baseband Version: I9100MUGKG2
Kernel Version: 2.6.35.7-I9100BUKG2-CL342890
root@DELL102 #2
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 4.0.1.5

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
Installation aborted.

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.

Rom manager is not compatible you've got to boot in to clockwork or use cwm app.

There's your problem, you should of searched on xda first.
Flash the cf-root kg2 kernel from here and you'll instantly get cwm recovery and root, and stop using rom manager.

Yeah I know. Thing is that I didn't find xda until after I rooted my phone because I wanted to know more and do more with it, hence xda comes in.
Thank you. I will do that. Now is there a step by step guide that I could look at just to make sure I could do it right. I got the file "CF-Root-SGS2_XW_MOT_KG1-v4.1-CWM4.zip" but not what do I do with it. Thank you for your help. Please refer me to the best guide for rooting my phone (if i need to do it again) and to a guide that also get's me through backing up my phone so that I could mess around with other roms and always be able to go back to factory state.
