Help out a noob in over his head ??

[bigrb9]

hey guys, I was bored at work today, and decided to finally root my D2. I followed the intsructions on here (z4, titanium backup, etc) but botched the install of liberty. I now I get stuck at the yellow fist and can't do anything else. I am not sure what OS version I was on, I know my phone was up to date with OTA verizon downloads though. I would be eternally grateful to anyone who may be able to help get my phone working again.
I searched and see that i need to "SBF" my phone, but not sure what that entails? I have downloaded the following zip files to my laptop since it looks like I need them:
rsdlite_4.8zip
USB_Drivers_bit_4.7.1.zip
VRZ_A955_2.3.20.zip

You can hold "X" while booting up, press both volume rockers at the manifying glass, and wipe data/cache.

i have gotten to android recovery, tried to load the sbf file by using "apply sdcard:update.zip" and i get an error msg- E:Can't open /cache/recovery/command then it says E:failed to open /sdcard/update.zip (no such file or directory) E:signature verification failed.installation aborted
starting to freak out a little bit here did i kill my droid?

[americanz]

no you didnt kill your droid. st off what version of liberty did you try to install?

[m1ghtysauc3]

That's not how you sbf. Do what urban said. Although it may not work now that you tried to install the sbf file like that. You may have to sbf. The right way.

pretty sure it was 1.5 ?
got it here : [ROM]One small step for man one giant leap for --- Liberty 1.5 2/2/2011

[americanz]

ok your good then did you do bootstrap recovery?

[bigrb9]

don't know quite what that is? All I can get to is the stock droid recovery screen, although I have made it to clockwork recovery 2times- the last time I tried to "update.zip" from sd card, but it told me my sd card was unmountable or something like that?

[americanz]

you dont want to do update from zip. when you get in to cw you need to clear cashe and clear data then try to reboot. should be able to do it from stock recovery too

[bigrb9]

previously cleared cache and cleared data, rebooted and just got the yellow fist coming up....I am thinking I probably botched the phone even further by trying to fix it incorrectly...
