i dont think it does, i think there's another option in cwm for that?
I get to CWM from reboot?

you can get into cwm from rom manager, if you dont know how to get into cwm since your device is a Galaxy s2 t-mobile, turn it off, hold power up and power button at same time untill you see the samsung logo.
A similar problem occurred with my Samsung Galaxy GT1900. The efs folder was corrupted and I was unable to fix that. Factory restore, rooting and installing a new ROM also didnt helped. There were few guides here to fix it by ourselves with some tweaking. But none worked.
The only way i made it work is that by buying a gadget called J-tang or just J tang.
By connecting J tang to PC and mobile to J Tang it manually pushes a new efs folder. But by this yout IMEI number will be changed and you will get a new IMEI number which will restore the mobile to working condition. That's how I fixed it.

Every modem I flash doesn't fix the problem either. IMEI and SIM card is not recognized either.
There's a problem with 1) your carrier, or 2) something is wrong with your sim.

Try ODINing. Had that problem with certain ROMs and Re-Partitioning fixed it.

I lost all my imei, baseband, phone number etc... after flashing to the blaze modem. I still cant figure it out.
Also, why are we supposed/instructed to use the pda option in odin instead of phone?

I did a backup through cwm. I did notice that after odin'ng back to stock, re-route and install of GO V2, everything was fine. Atleast till i restored my backup. I made a backup after flashing the blaze modem so I am guessing it saved that crap in my backup.
Is there a way to leave out that part of my backup? Atleast that way I can still restore all my apps and settings?
There is option for advance restore

Since you can only access the upgrade screen you need to update it with the correct factory dload file it maybe here or Google it

I read in one of the threads that if your IMEI is good (mine is, have yet to flash a ROM), that you could simply copy the EFS Directory from your phone to the SD card, etc. I copied the entire EFS folder to the internal SD card and also to my PC. Two questions:
1. Is this all I will need in the event I somehow lose my IMEI
2. When I look in the IMEI folder inside the EFS folder it is only 3 bytes, doe that really contain the IMEI
3. (ok, I lied about the 2 questions) I read someplace that if my bootloader is unlocked (which it is), I didn't have to worry about losing the IMEI?
Thanks

Unlocked or not, you can still lose IMEI on any reboot.

Is this the best way to back up now? I remember that there was once a method using dd. But it's didn't always restore correctly right? Are there any other methods?

This is the standard way to backup your IMEI. The old method is not as comprehensive, read the OP of the method that you quoted and you will see why this way is more complete.

So I'm trying to fix a phone for someone but I can not find a way. Basically the phone says the IMEI is all 0's and even if you put a sim in it has a O with a line through it instead of service bars but still shows the 4G icon. Also it has all this stuff written on the screen that I've attached pictures of. Going into the settings says all 0's for the IMEI. I've tried factory resets and using ODIN to flash stock but no luck, I've thought of just restoring the IMEI but not to sure that would solve it
Yeah it looks like you need to restore the IMEI. Worth a shot
EFS is wiped and needs to be reprogrammed. Did this happen randomly? You can take it to Verizon and they can fix it as long as the device isn't blacklisted.

Can you get the phone to download mode? If yes you can get the phone restored to original settings. Based on this picture your kernel might be messed up. It is just a guess.

Quick question: if I make a nandroid back up of this skyrocket and I get a new skyrocket via att can I move the nandroid to the new phone and restore it to the new phone and have my new phone running right where I left off??
Has any one done this? Is this safe to do or can it mess up the new phone?
