Prompt [BOOTLOADER][SCH-I705] VZW Galaxy Tab 2 7.0 LTE bootloader UNLOCKED!

The Verizon Galaxy Tab 2 7.0 LTE now has an unlocked bootloader!

****
!!!!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 you are on VRBMI1 and have semi-bricked using this method, flash this stock ODIN image using ODIN 3.04 if you are able to get to download mode.
DO NOT CHECK RE-PARTITION, FLASH LOCK, OR LED CONTROL

VRBMI1

The above information is unknown to me. Do all at your own risk!

YOU HAVE BEEN WARNED
****

READ FIRST
*** *** *** *** Disclaimer *** *** *** ***
I am not responsible if you break your stuff. READ READ READ
If you DO NOT own a VERIZON Galaxy Tab 2 7.0 SCH-I705 then DO NOT flash this! If you have not verified and flash this on a p3xxx tab, something will break and I will not help you!
Verizon MAY find a way to block this in the future. But for now, it works.


We have gained access to an insecure bootloader (aboot.img) from a "prototype" VZW Galaxy Tab 2 7.0 obtained by XDA user id_ram.

How to unlock:
1. Root your device using my guide How to root your VZW G Tab 2 7.0 LTE
2. Download this insecure aboot.img to the root of your SD Card Insecure aboot.img
3. Make sure the MD5 of the above image matches this: f4fbc4c5056f62498b378873bf8e3dca
4. Turn ON USB Debugging: settings > developer options > USB Debugging (checked) [Should have already been done when you rooted!]
5. From Terminal emulator or ADB do the following:
6. MAKE SURE TO VERIFY BOOT LOADER STATE BEFORE FLASHING ANYTHING ELSE!
-Download mode will appear landscape
-SAMSUNG boot screen will flash very quickly
Don't confuse the L with a 1 !!!
CORRECT: mmcb l k0p5
INCORRECT: mmcb 1 k0p5
If you want to verify p5 is your bootloader (aboot), run the following command as root
Code:
cat /sys/block/mmcblk0/mmcblk0p5/uevent
If you see this: PARTNAME=aboot, listed in the output you can continue.
If it does not say PARTNAME=aboot, STOP HERE
From ADB
Code:
adb shell
su
cd /sdcard/
dd if=aboot.img of=/dev/block/mmcblk0p5
reboot download
From Terminal Emulator
Code:
su
cd /sdcard/
dd if=aboot.img of=/dev/block/mmcblk0p5
reboot download
Congratulations, you now have an insecure bootloader!

NOTE: Download mode will always display QUALCOMM SECURE BOOT: ENABLE regardless of bootloader state. Don't know why, but my VZW GS3 is the same way.
NOTE2: #1 way you can tell your bootloader is unlocked is that you can dump your stock recovery.img, repackage into ODIN flashable tar (unsigned tar) and flash it with ODIN. #2 way you can tell your bootloader is unlocked is that the initial SAMSUNG splash screen display time is reduced to less than 1 second.

Once you got custom, NEVER accept an OTA!. Verizon released an OTA for the SCH-I705 that makes changes to recovery, boot, and aboot, THIS WILL MOST LIKELY BREAK YOUR ROOT AND UNLOCKED BOOTLOADER! DO NOT ACCEPT!

TO RETURN TO STOCK BOOTLOADER
Visit the original ROOT BOOTLOADER RECOVERY STOCK thread and go to the bottom of the OP:

Thanks to:
id_ram - for his "prototype" tab and his insecure bootloader!
AdamOutler - for SGS3 bootloader unlock method, which is where I got the information needed to flash this one

Just like to say Congrats. Hopefully you can get some stuff from the US SGS3 ported over since the hardware looks similar between the two. Happy Hacking

Oh, I'm no developer.. I just put a lot of time and a lot of research into this and finally found id_ram (well, he found us!). Was just a matter of getting his tab to boot again and then dump his aboot.

Give me a few more weeks, once I actually start getting into ROM development, then maybe

I'm really glad my tab is wifi only. I suppose lte would be neat but I leave it at home anyway so it would be a waste of money to not just use wifi.

I have att and lte here is super fast. Anyone care to share a speedtest screenshot?

I think its awesome that you guys are getting the development going on the not so popular gtab2. Good luck to all of you.

LTE here in the Chattanooga area is crazy. Our Fiber Optic internet is up to 1 gbps thanks to EPB Fiber Optics.
