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.
[Galaxy Tab 2 7" Android Development] BigBot96:
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.
[Galaxy Tab 2 7" Android Development] Xer0daze:
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.

Ok I am trying again to root this tab. I actually bricked the first one on the unlock bootloader stage. This time around Im getting the same errors about the phone and google stopping. Last time I just ran the tar again through odin and it went away after the second run. but now I am on the third run and still getting the pop ups on reboot. When u say reset are u meaning to do a factory reset from system recovery mode? because i may try that if it doesn't work this last time around.

!!!!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

VRBMI1

http://garrettek.com/android/SCH-I705/ROMs/4.1.2/HOME_I705VRBMI1_1415457_REV02_user_low_ship.tar.md5

new root

So since there is a way to root the update now is there a way to unlock its bootloader? Would the old way work now or did something change?
[Galaxy Tab 2 7" Android Development] BigBot96:
I'm 99% sure the boot chain has changed.. thus old bootloader will result in hard brick. I could be 1% wrong though.
[Galaxy Tab 2 7" Android Development] xxxericxxx:
Yeah that's what I figured, is there any one left to unlock new bootloader now or is just root all that can be achieved. I think I got kind of spoiled with an epic, the Devs worked magic on that forever.
[Galaxy Tab 2 7" Android Development] BigBot96:
Root is all that can be acheived. The previous bootloader wasn't unlocked, but more like a Samsung development, unlocked bootloader was found on a prototype tab and found to be compatible. This will 99.9999% not happen again for this device, or any other.
[Galaxy Tab 2 7" Android Development] Uncleheff:

[Galaxy Tab 2 7" Android Development] MrRedPants:
So. Just to be clear... If the OTA update was taken to 4.1.2 VRBMl1 there is no way to "downgrade" via ODIN to unlock? I just picked one up of craigslist. Good to know can get root... But aggravating to be stuck at 4.1. Thanks MrHyde
[Galaxy Tab 2 7" Android Development] BigBot96:
I don't know, I never attempted. But in assuming no. You can attempt a downgrade via official stock Odin package. It should just fail if it won't work and not flash. I can't be certain though.
[Galaxy Tab 2 7" Android Development] MrRedPants:
Googling finds references to the procedure. In your OP under return to stock...perhaps applying that firmware using one of the methods may work.

https://www.google.com/search?q=can...mobile&sourceid=chrome-mobile&espv=1&ie=UTF-8

I currently am on a Note 2. I may reach out to some others in those forums to see about the procedure. If I can get back to when it was unlockable...KitKat here we come!

I can confirm saferoot method on my tab as well running VRBMl1. I ran it on stock ROM that came with tablet. I did need to run the install.bat file from saferoot as admin on windows 8
[Galaxy Tab 2 7" Android Development] MrRedPants:
I am finally getting around to testing this out - Mr Hyde (or anyone) - I need a copy of the original stock VRBLL2 image

I705VRBLL2_I705VZWBLL2_VZW.zip

I am going to downgrade to this firmware and then root, unlock bootloader and go from there.

EDIT: I found a source for the stock - but, that said - I can't seem to find any ROMs whatsoever for the sch-i705 other than MrHyde's previous work on the doubleshot ROM - perhaps using that based on original release will work better than the latest verizon, I don't know. Downgrading to a point of an unlocked bootloader would make sense only if there were a ROM to put on it! As there isn't - it would seem ROOT is the best we're going to see right now. My main issue with the device has been storage, however I am going to try swapping int card with ext and see how that goes - per here: http://xdaforums.com/showthread.php?t=2017774

Mr Hyde - would you recommend staying on latest verizon firmware rooted or your doubleshot ROM - if you were me. Don't worry, if it bricks the device I won't hold you responsible!
[Galaxy Tab 2 7" Android Development] BigBot96:
I would recommend DoubleshotROM. The update.zip from LL2 to MI2 was less than 50mb so there can't possibly be anything substantial in the update other than attempting to lock it down by flashing a new boot chain.

Besides, DoubleshotROM already has the SD SWAP mod and a pretty high overclock.

VI? Are you referring to VRBLL2 or VRBMI1?
[Galaxy Tab 2 7" Android Development] evrkusd:
Is it possible to flash an upgraded version of the OS (4.2 /4.3 /4.4) once you have the custom bootloader?
[Galaxy Tab 2 7" Android Development] MrRedPants:
Yes, sorry, wherever I wrote VI I meant VRBMI1 (from your OP)

Only odd things was after using ODIN to flash stock VRBMI1, the apps I had installed originally (prior to trying to flash VRBLL2) were still there (including superuser), however root was gone. Probably need to do wipe data in stock recovery I assume. So, if I do a last ditch, I'll go into stock recovery, do a full wipe, then try to flash stock VRBLL2 one last time - there's no reason it shouldn't work (in my head). Unless the file is bad but it passes md5.

---------- Post added at 04:56 PM ---------- Previous post was at 04:54 PM ----------

Well that would be the goal, and, unless Mr Hyde says otherwise, in theory, yes - but that means someone (a developer) has to take an AOSP ROM (like cyanogen) and make it work on Galaxy Tab 2 hardware. Without a developer with the motivation to do that, then no, best we get is Jelly Bean ROM as mentioned previously.
[Galaxy Tab 2 7" Android Development] BigBot96:
I posted this in the big warning box in the OP

With that in mind, if the downgrade to VRBLL2 is failing, then Samsung updated their signatures and any attempt to downgrade will be met with failure. You would have to downgrade the entire boot chain at one time, which, as far as I know, is impossible without a JTAG.

In short, you're stuck with VRBMI2 rooted unless somebody updates/releases a ROM based on MI2

without

the kernel. I'm not even sure CWM/TWRP will work anymore.
[Galaxy Tab 2 7" Android Development] MrRedPants:
To put some closure on this - with root and some tweaks - the tablet actually runs pretty well. My approach was to obtain root using saferoot as earlier in this thread, install jrummy's rom toolbox pro - combination of uninstall and freezing bloatware and obtaining SD Swap as here: http://xdaforums.com/showthread.php?t=2017774

Doing this and using Nova launcher it's not a bad little tablet at all.
[Galaxy Tab 2 7" Android Development] BigBot96:
You could see if safestrap works. The s3 and i705 were the same when it comes to hardware. Just make sure you use the s3 version.

Im unsure if safestrap could brick, though. If it works, then you could run custom roms of the same build.

Just an idea.
[Galaxy Tab 2 7" Android Development] MrRedPants:
Funny. When I first got it I messaged hashcode about safestrap. He said he hadn't done one for the tab but he thinks it would work. At the time I didn't realize the similarities in the two devices (s3). But even if it did work... I'm still only able to use the one room you did.

I actually don't even see an s3 version

Hey, been thinking more about this and talking with a few people. What's the process for starting a bounty on something like this? Or even hiring someone to do it? I've seen bounties etc. on xda before, but don't really know the process.
