CAN ALSO WORK ON VRBMI1
It has been said the following root method: saferoot
Has been able to root VRBMI1. Give this a try before using the system image below.

****
!!!!WARNING!!!!

Many of you have been complaining about broken wifi and other issues.
I do not own this tablet anymore, which means I can no longer support it.

Verizon/Samusung released a new update: VRBMI1
Check your firmware version
THE LAST VERSION SUPPORTED BY THIS GUIDE IS VRBLL2.

IF VERIZON/SAMSUNG CHANGED THE KEYS THEY SIGN THEIR FIRMWARE WITH, THAN ANY ATTEMPT TO DOWNGRADE/UNLOCK MAY POTENTIALLY BRICK YOUR DEVICE.
This has been seen on the VZW Galaxy S4 and just recently the VZW Galaxy S3 (The VZW Tab 2 is a clone of the S3!)

If you are on the latest build (VRBMI1), then it is entirely possible things will not work. It is also possible the bootloader unlock may brick your device.

If the root method doesn't work, flash a stock odin tar for VRBLL2.
AGAIN... IF VERIZON/SAMSUNG CHANGED THEIR KEYS, YOU MAY BRICK!

If you are on VRBMI1 and have semi-bricked using this method, flash this stock ODIN image using ODIN 3.04.
DO NOT CHECK RE-PARTITION, FLASH LOCK, OR LED CONTROL

Good job man. I hope the vtab gets its own development subforum here. Xda has a request thread for new threads for new devices. All of you with these new tabs should go post in it.

Edit: this is the thread. http://xdaforums.com/showthread.php?t=1660354

I posted in it in hopes of getting it done. Good luck vtabbers

Are other apps such as TB, Terminal, or AdFree Android able to gain root privileges? If so, then Busybox Installer may have been denied. Check Superuser and remove it from the Denied list if it's there. After removing it, try again and make sure to tap "Allow" when it asks.

EDIT: Downloaded that app to test. SU asked if I wanted to grant SU permissions, tapped 'Grant'. All is fine. If it's NOT in the SU denied list, Force Close the app. Reopen it and it should ask.

This is awesome. Thanks! One thing - is there a way to stop the OTA update nag?

Xer0daze · Nov 12, 2012

Thanks, I did that. I also noticed in system/app there were SDM.apk and SDM.odix. I went ahead an renamed them SDM.apk.bak and SDM.odix.bak. I'm hoping this will get rid of the nag notification. One last thing - the update tried to run overnight once but CWM stopped it. When I woke up the tab was sitting on the CWM screen. Since then every time I reboot the tab it acts as if dalvik cache was cleared (I get the "android is upgrading - optimizing applications" screen before the tab loads). I think OTA set a reboot/clear cache flag somewhere I need to clear, but I don't know where that is set. Any ideas? Thanks again.

BigBot96 · Nov 12, 2012

That will get rid of it. As for the reboot issue, have you tried clearing cache? Or even a factory reset? Factory reset won't hurt your root any nor restore the update app.

Xer0daze · Nov 14, 2012

Thanks for the reply - Yep. I factory reset a couple days ago and made the update changes mentioned earlier. I no longer get the OTA notifications (YAY), but every time I restart the device it still rebuilds cache. I've formatted the cache partition, cleared dalvik cache, and as I mentioned, I tried a factory reset as well. This is the only hurdle I have left to clear. Out of curiosity, why are there no custom roms for the VZW version of this device? The VZW version doesn't carry the same model numbers as the retail models (GT-Pxxxx). The verizon device is simply SCH-I705 - there don't seem to be any roms for that. Isn't the only real difference the radio? I've asked around the forums, but not gotten a reply from anyone on this. I'd love to try some custom roms on this tab, and I'm sure that would fix the majority of my issues, but I have yet to find one.

BigBot96 · Nov 14, 2012

There is actually a big difference between the wifi and lte devices. The i705 is closer related to the i535 (gs3) than it is the wifi tab 2's. And there are no custom ROMs yet becuase there are so few of us that own it, and even fewer (two of us actually..) who are trying to get anything done on it. I'm a novice developer so I'm still learning the process of ROM development. On top of that, I'm very busy working two jobs, saving up for a wedding. Unless someone else is capable of getting more development done we may only have 1 or two custom stock roms floating around, which is what I'm working on ever so slowly. CM10 and the others a bit out of my league right now.

If anyone wants to try to bring more attention to this device, feel free to do so. It'd be helpful to have people who know what they're doing more than me.

Xer0daze · Nov 14, 2012

MrHyde03 -

Thank you so much for the detailed information. That is exactly what I've been looking for... exactly THAT. Congrats on the upcoming wedding by the way. That's awesome.

I might be willing to donate or lend a device to the right person if potential exists for that to result in a working Rom.I wouldn't know where to begin on that. I am in the Seattle area but can ship if necessary. I like CM10 and have Paranoid Rom (based on CM10) running on my GS3 and I'd absolutely LOVE to have the same features on my SCH-I705. I have the tab mounted in my car and It's a really great device, but the stock rom is HORRIBLE. For one, this 'loud volume warning' (whenever playing music over headphones or line output, it decreases the volume because, according to Samsung, I'm not a big enough boy to make my own decisions with regards to my own hearing) is driving me absolutely crazy. My GS3 did the same thing, but since I've rooted and loaded custom roms on it, I've loved it.

Thank you again for being one of the few to reply to my questions and for providing these details, you are appreciated.

I'm getting this:

Step 1 - Pushing files...
failed to copy 'debugfs' to '/data/local//debugfs': Permission denied
failed to copy 'su' to '/data/local//su': Permission denied
failed to copy 'debugfsinput' to '/data/local//debugfsinput': Permission denied
failed on '/data/local/tmp' - Permission denied
link failed File exists

Rebooting...
Once your devices has finished restarting,
Press any key to continue . . .

Step 2 - Rooting...
For this step, ignore any error messages that say "File not found"
Unable to chmod /data/local/debugfs: No such file or directory
/system/bin/sh: can't open /data/local/debugfsinput: No such file or directory
rm failed for /data/local/tmp, Permission denied
failed on '/data/local/tmp.bak' - No such file or directory
rm failed for /data/local/su, No such file or directory
rm failed for /data/local/debugfs, No such file or directory
rm failed for /data/local/debugfsinput, No such file or directory

Rooting FAILED! You may want to try running this tool again.
Your device region may not be supported if you see this message again.

Press any key to continue . . .

Could this have anything to do with me not yet having a sim card for the device (region??)?

I get permission denied errors when trying to push su and other files. Cannot obtain root. Any help?

BigBot96 · Nov 22, 2012

What version android do you have? This is only confirmed on 4.0.4.

4.0.4

I'm gonna try again today now that I have a sim, but I doubt that's the issue.

Looks like we're having the same problem.

RevosFTS · Nov 23, 2012

Yeah we have the same exact error. I am tempted to try manually pushing the root files through adb. I may have to call the banners though. Perhaps Liquid would be willimg to help.

Scott · Nov 23, 2012

Damn, if I had only seen this before I went TO the Verizon store, lol.

Oh well. I was just going to root and get a ROM out for everyone.

If anyone finds root let me know and I can start ROMS!

OP: You should put "not working" in title so people dont fill the thread with.. OMG it doesnt work!
