How did you get aboot into root? In xplore when I long press the aboot, move isn't in the list of options if root is the other pane. Seems like a couple other options are absent too
[G Pad 8.3 General] roirraW "edor" ehT:
Did you enable X-Plore's root write options in it's settings, and grant it root priveledges when it asked? You can check in the SuperSU app to see if you've accidentally denied it permissions.
[G Pad 8.3 General] APRock:
I had a slightly unpleasant experience with this. Went through all the steps and everything worked fine. So I HAD to try the aboot swap to TWRP recovery to work..... 1st off, what the file manager your using "thinks" is the top of internal storage may not actually be. Some hunting and pecking, lots of "LS" commands in terminal and I found things I needed and got them where they needed to be. Flashed the older aboot, TWRP recovery worked fine. So, I then used TWRP to flash the 36b aboot (perhaps that was the mistake, should maybe have done the terminal commands like before), and the tablet would not boot up. If I remember correctly it was some sort of security error. Anyway, started over from step one and got it back. Now that I know I can get it back I may have to go through it again so I can get the exact error messages if folks are interested.
[G Pad 8.3 General] roirraW "edor" ehT:
If you were on the 36B ROM, then flashing the 36B aboot zip that I provide was the correct thing to do when you were done in TWRP - don't know why it would cause you problems unless you were actually on the 35A ROM, which would require the 35A aboot. For some weird reason a lot of people seem to use the 35A ROM more than 36B, I think because Google search results.

I've never used TWRP's built in Terminal Emulator support.

Did you check the MD5 hash of the 36B aboot zip?

There's likely nothing I can do about any error messages you received or receive again if you have trouble again. It works fine for me - I've put the 11A aboot back on, done what I wanted in TWRP v2.8.7.0 and then flashed the 36B aboot zip to get back into the ROM at least two dozen times, if not more, so the 35A/36B confusion is my best guess, but please look in the Settings/About/Software menu and see what build you're really on, and let me know what you find out.

Is cm-12.1-20151019-UNOFFICIAL-vk810 a reasonable alternative? I'm finding the booby traps around switching bootloaders for the rooted KDZ ROMS more misery than I want to deal with. I've had good luck with CM 11 on my Nook HD+. It's a very stable environment. How stable its CM 12.1 for the VK810? The other alternative I'm considering is to stay at 4.2.2 rooted.
[G Pad 8.3 General] roirraW "edor" ehT:
That depends on your definition of reasonable. :) Although I don't recall if I ever tried that particular (last build) by [MENTION=2385005]invisiblek[/MENTION] , I never could get mobile data working on any builds of CyanogenMod. He was working at it and someone even had some luck getting mobile data they said but then I believe it stopped working. On the same build as that guy had success, I couldn't get it working at all. I don't think GPS worked either, and I don't recall if Bluetooth worked. WIFI, of course, did work.

I also didn't consider any ROMs based on CM for the VK810 to be very stable as far as memory leaks and such - I'm sure if there had been more development that it would eventually become much more useable.

I'm working on re-doing my debloat for 4.4.2 KitKat 24A as I'm tired of how laggy Lollipop 5.0.2 is for the VK810, and it won't hurt that I won't have to do the aboot trick any more. I'll upload everything including the 24A ROM when I'm ready - whenever that'll be. Apps were organized differently pre-Lollipop which is why I have to do the debloat differently.

I will miss some of the things I got used to on Lollipop but I believe I can replace all those things with apps.
[G Pad 8.3 General] AirForceOnes0010:
Thanks for the help. I had enabled superuser+ in xplore for one of the earlier steps but for some reason it was back in normal mode. Then moved aboot to root just like you said, the command line change /aboot worked like a charm and flashed the 36b aboot off the ex sdcard. This little device is now complete, thank you very much!
[G Pad 8.3 General] roirraW "edor" ehT:
Excellent! You're welcome!
[G Pad 8.3 General] o4tuna:
First off, THANK YOU!

An extremely clear & concise, step by step walkthrough.

I'm thinking about not going past the "Flash to the latest stock ROM step."

Is there any really compelling reason to upgrade to 5.0.2?

My tablet came with this, and I had trouble getting several things I liked to run on it.

Or the 4.4.2 you mentioned above in reply to b52apl?

I will NEVER use the 4G data on this thing, wifi only.

I want to use it for browsing, media playback & games.

I bought it with the intention of using apps2sd to install things to the sd card, apps2sd didn't like lollipop at all. tried to go the Xposed framework method, but 5.0.2 ain't supported.

Both those seem to work ok with 4.2.2. My only concern would really be some of the more malevolent thinks like heartbleed. Are things like that patched in your version of 4.2.2 or 4.4.2?

Are there any features of 5.0.2 that I'm totally missing? It seems like a little UI sprucing up at the expense of a bunch of stuff that was added for "security" - keeping me from using/ modifying my computer in the way I see fit.

Any progress on the 4.4.2 you mentioned above?
[G Pad 8.3 General] roirraW "edor" ehT:
You're very welcome, and thank you! Personally, I don't think there's a compelling reason for Lollipop on this tablet. As you may have read me saying, I used it on Lollipop for a year (although had reinstalled several times in the course of testing things, etc), and first, Play Store updates take much longer on Lollipop on this tablet. We're talking about 20 minutes for 10 updates. I don't know if it's Lollipop 5.0.x that's to blame or Play Store/Play Services updates, or what. KitKat runs like butter for me. On the VS985 G3, 5.0.1 was also kinda sucky, just not as bad as on this tablet, but that has a much better processor. 5.1.1 on the G3 made things perfect.

Xposed is supported on Lollipop and above - there is a separate thread for the Lollipop and above Xposed. Easiest way to find it is to Google:

Xposed Lollipop

There are no updates for the KitKat version in that thread, of course, and Xposed no longer has a built-in framework updater, probably because the author is just so busy enough bugfixing the newer Xposed in the past that's just one detail too many, and perfectly acceptable by me. There will be technically unpatched security flaws in KitKat, but a far as I'm aware the biggest ones deal with possible hijacking due to malicious but not necessarily looking malicious MMS, and although you can put Verizon Messages on the tablet, and using Mobile Data/WIFI you can have it sync with Verizon Messages that you use on another device - that may be the only way that the biggest security flaws would be taken advantage of on the tablet. I tried the syncing and I thought it was just annoying so I don't use Verizon Messages on the tablet anymore, although I do like it for the phone after resisting for quite a while.

I digress.

The pre-rooted KitKat ROM is technically finished and has been for quite a while, I just haven't had time to finish the extreme debloating zips, since I like to include them as optional, and have the full relatively untouched ROM as a base. I may just go ahead and upload what I have so far so that anyone who still uses this tablet can benefit since over time there'll be less and less VK810 users, if people upgrade/trade or break theirs. I'll try to do this later today. If I don't get around to it by next Friday, feel free in this case to bug me one more time, but I'll set myself a reminder to try to work on it.

Note that you can use Stump root on 24A (what the not uploaded pre-rooted ROM is based on), so you could flash the 24A KDZ, root it using Stump's brute force method, and then debloat it yourself. And you can still downgrade the bootloader to install TWRP if you wish.
[G Pad 8.3 General] o4tuna:
Yeah, just picked up this tablet off ebay for cheap. Had been looking for a reasonably priced tablet with 2 Gigs of ram, ran into several articles that said the 8.3 was an under appreciated gem. Excellent condition, $77. Thinking about getting a 2nd one for my Son-in-law.

Xposed: Got some kinda error about the sdk on the tablet being too high. Wasn't sure whether it was actually because of the seller updating everything to the latest, kingroot, or something else. Was having some questions / difficulties in regards to kingroot, anyway, so downgrading & a proper rooting seemed like a better path to explore first.

Yeah, not texting with this. Just browsing, movies & games. Hate verizon with a passion, wifi only for data.

Debloated KitKat would be AMAZING!
[G Pad 8.3 General] Udonitron:
I am on stock 4.4.2 and rooted.

I can flashify the newest TWRP and it boots into it but I think due to everything being encrypted on the stock tablet I show 0MB for internal and thus cannot flash.

I assume I would have to do a full wipe to get that working?
[G Pad 8.3 General] roirraW "edor" ehT:
I'm unfamiliar with any kind of encryption on this tablet in any circumstances.

Some versions of TWRP don't see the storage correctly. Are you using the version I linked to? I don't use Flashify, I just boot to the old version of TWRP and then flush the updated version from it.

If all else fails is start back at the beginning. I can't tell you how many times I followed this same process.
[G Pad 8.3 General] Udonitron:
Cheers for the reply.

I was using the latest TWRP.

Yeah your TWRP link goes to the Rooting VK810 official stock release 11A page and the link at the bottom for TWRP goes to the same page haha.
[G Pad 8.3 General] Udonitron:
So if I am rooted on 4.4.2 I should downgrade and then do your steps?
[G Pad 8.3 General] Android-gig:
Amazing!! in one word

Thanks for your amazing detailed and well explained tutorial.

Every step so well explained :):)
[G Pad 8.3 General] roirraW "edor" ehT:
Well thank you very much, and you're welcome!
[G Pad 8.3 General] aneece98:
Will this work if I'm on 5.02?
[G Pad 8.3 General] roirraW "edor" ehT:
If you follow all the directions which includes downgrading.
[G Pad 8.3 General] aneece98:
Thanks. I just wasn't sure that the flash tool would downgrade bootloader as well
[G Pad 8.3 General] roirraW "edor" ehT:
You're welcome! Yessir, KDZs and TOTs replace "everything" although TOTs replace just a tiny bit more than KDZs.
[G Pad 8.3 General] spock74:
Driver version different

I'm about to try this because I've tried rooting before and it's sort of worked, but not really, and you've presented what looks like a very well explained way to do it that makes sense to me. Before I start, though, as I'm getting ready to download the driver from LG, the version is now 4.2.0 rather than the 4.0.3 stated in your tutorial. Maybe I'm being a littlelot paranoid, but do you think that will make a difference? I'm sorry if this is a really dumb question, I just want to make sure...
[G Pad 8.3 General] roirraW "edor" ehT:
Thanks.

No.
[G Pad 8.3 General] spock74:
Am I confused?

I think I might be flailing around a bit here. When I put the tablet into download mode should it show up as a connected device on my PC? I've got the flash tool running but it says the phone is disconnected from the PC. Maybe I need a different cable? I'm feeling dumber about this than I think I actually am.
[G Pad 8.3 General] bakkiss:
Is it possible to flash Magisk on VK810 after all your steps?
[G Pad 8.3 General] Magendanz:
You can skip quite a few steps installing TWRP by just copying the latest .img file to the home directory and entering this in Terminal Emulator:

su
dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
reboot recovery

X-plore File Manager is not needed.
[G Pad 8.3 General] Magendanz:
Okay, here's a build of TWRP Recovery 3.1.1-0 for the VK810: twrp-3.1.1-0-vk810.img

Just use the commands above from any Terminal window to install.

I built this from the official TWRP project for the V500, but used the kernel from the v2.8.7.0 build linked in the OP. Note that I remove the nag dialogs to install the TWRP app in all my builds, as I find them annoying (in a very Microsoft way).
[G Pad 8.3 General] SethNkC:
Will this TWRP work on the vk81035a update? 5.0.2

thanks
[G Pad 8.3 General] Magendanz:
No, you've still got to downgrade to the KitKat 11A bootloader, but once you've rooted you can flash to this TWRP image directly.

BTW, here's a newer build: twrp-3.2.1-0-vk810.img
[G Pad 8.3 General] alado221:
the links for the original 2.7.0.1 twrp link are dead. i wish someone could upload them again.
[G Pad 8.3 General] masterx1234:
Are you saying we can just flash that 3.2.1.0 without already having a previous version installed? Because all the TWRP links by this threads creator are all dead.
[G Pad 8.3 General] Magendanz:
Yes, once you've rooted the device, you should be able to just flash the latest TWRP from a terminal window using the "dd Install" method documented here. And, I just posted TWRP v3.2.2-0 on this thread.
[G Pad 8.3 General] masterx1234:
Thank you so much!! I have now successfully rooted and installed TWRP and im now in the process of downloading some custom ROMS. you are an absolute life saver, I was going mad finding so many dead links. I never had to mess with the loki commands or anything. I want to leave this comment for anyone else who gets this model and has lollipop. Downgrade to the lowest version of kitkat once you get it with the LG Flash Tool 2014 version and then run stump root then install super SU and reboot, then put the TWRP version from the above comment on the root of your SD card and just install any terminal app on your device and simply enter the DD commands. Its that simple.
[G Pad 8.3 General] omarjuvera:
Yeeea....except that you forgot to include the link to such ROM.

Found the original post and was able to root the VK810 by downgrading + Stop.

However, noticed that some of the links are broken and some steps may seem unnecessary since I was able to use TWRP App to flash the most recent TWRP.

Right now, I have a Downgraded and rooted tablet. Can't figure out how to "Flash to the latest stock ROM so that you can have it with root"

Weeelp!!!

Can you help me do it with stock roms? (.kdz)
[G Pad 8.3 General] roirraW "edor" ehT:
Actually, no I didn't (see screenshot attached). Try loading in a browser in desktop mode.

You'll have to be more specific about what links are broken. All of my own uploads are always at Android File Host. Let me know if you're talking about my links or links I have to other people's stuff, and which links and maybe I can help or put duplicate copies of specific files in a different place.

If the reason you "Can't figure out how to "Flash to the latest stock ROM so that you can have it with root" is not because of broken links, please give me more detail of what part of the process is problematic.

Meanwhile I'll quickly check to see if Google Chrome had mangled my links the last time I edited the OP although I've long been on the habit of avoiding the cause of that and of double checking once I saved an edited post.

Might be a few hours before I can get to that, so if you can fill in the details before I can get to it, that will help.
[G Pad 8.3 General] o4tuna:
Hello, I'm still using the tablet. Finally ran into a game that I want to play that doesn't work on 4.4.2, so decided it's time to update to 5.0.2.

Booted into TWRP, wiped everything, stuck my sd card with all the files on it in, and it won't load the image, says

gives me an error something about no bootable system installed, I think (it's been a month, & I have a lousy memory)

Couldn't get back into twrp to see what the error says, now gives me the stock reset/wipe/safe screen

If I choose continue reboot, I get "Secure booting error

Cause: boot certification verify"

If I choose factory data reset, it goes to are you sure screen, then goes to sleep

If I choose wipe, it starts the ModeBackup & Restore page, then it goes to sleep

Safemode boot does nothing

If I try to boot normally, I get:

"Secure booting error

Cause: boot certification verify"

Was going to redownload the files, but they seem to no longer be on android file host.

Any thoughts?

Did I brick it?

Any backup location for the files?

Any chance that if I connect it to the PC and start at the beginning it'll come back?
[G Pad 8.3 General] roirraW "edor" ehT:
Sorry for the very late reply. I hope somehow you found the solution by now but in case you didn't, yes you did brick it but just software bricked, not hardware. From memory (and I am very rusty on this device) you have to flash the TOT file. You can get from the link in my signature below regarding VK810 KDZs and TOTs.
[G Pad 8.3 General] Bobberino:
It looks like the download link for the VK810_twrp_2.7.0.1.zip and VK810_twrp_2.7.0.2.zip are dead. Any chance you still have access to these? I need to follow this thread before I can follow the initial thread you provided, since it says 'no space left on device' when trying to following other instructions to flash 2.8.7.0 with 4.4.2 installed.
[G Pad 8.3 General] roirraW "edor" ehT:
I'll answer both of your posts here. I didn't realize that; I checked, and I don't have any copies of those, sadly. I hope you can find them with some general internet searches.

I don't think removing bloat would help succeed, as that won't increase the size of the recovery partition. I assume you were attempting to flash the newer version of TWRP directly (as opposed to flashing the old 2.7.0.1 since that link is dead)? I only ever knew the verbatim ways outlined in these threads. I wish I had better news for you.
[G Pad 8.3 General] Bobberino:
yes sadly that did nothing; but fortunately didn't brick again!

I am now trying to follow your instructions here: https://xdaforums.com/t/vk810-4g-al...tall-a-custom-recovery.3283027/#post-64601845,

to downgrade to 4.2.2 so I can install 2.7.0.1 and then v2.8.7.0...

I'm stuck in LGflashtools 2014 saying I need to "install CSMG B2C client TOOL" and when I got into the menu and select 'install' it says successful, but when hitting start to flash nothing happens.

I searched for that client tool and found it, but the install gets hung up around 10% and doesn't budge. I have tried installing it with different compatibility modes set in windows and all AV disabled, with no dice.

I of course was able to get the other LG Flashtools program to work, because I followed @Lostwon's guide which used different variety flash tool.

I'm on Win 10, any ideas how to get Flash tools to work? or is there a different .exe of it I should grab somewhere else?

I feel like I'm so close and think next steps should be: Downgrade 4.2.2 > TWRP 2.7.0.1 > TWRP 2.8.7.0 > Remainder of LostWon's guide.
[G Pad 8.3 General] roirraW "edor" ehT:
Does that mean you found the TWRP 2.7.0.1? That's good news if you did. That sounds very vaguely familiar, but I don't really remember.
[G Pad 8.3 General] Bobberino:
I believe so, the issue I am running into is getting LG flashtools to work for flashing the 4.2.2 kdz from your guide here-

Is there a definitive guide for the 4.2.2. downgrade? I am trying to follow this one: https://xdaforums.com/t/vk810-4g-al...o-root-and-install-a-custom-recovery.3283027/

But in between the top two posts, there's no mention of what Android version we should be on before going to TWRP steps.

A better way to ask: Is there a 4.2.2 .tot and respective dll file I can just load into the flashtools software that is working for me, and further downgrade it? My head is spinning trying to keep all these threads, tools, drivers, updates, extensions, etc. straight!

At this point what works for me is the Download Mode LG Flashtool + Uppercut + .tot file + dll file and then flashing to device, as mentioned in LostWon's instructions:

[VK810.4G] [altev] OTAs, .IMGs and KDZs, oh my (and one 22B TOT too) updated 4-6-2016

Thanks to everyone over the past almost six years who helped me get to the point where I am so far. Glad to help others in what ways I can. Thanks to bweN diorD for his Verizon LG G3 VS985 repository. Inspired me to do this for the VK810.4G...

[G Pad 8.3 General] roirraW "edor" ehT:
I don't think there was one specifically for this device, but I always found I could flash the 11A_01 4.2.2 KDZ the same way as flashing any other. I know the .TOTs were more useful, but they were also rarer.

https://xdaforums.com/t/vk810-4g-al...o-root-and-install-a-custom-recovery.3283027/

See below (from the top of that OP):

There is only one .TOT (and .DLL) available, which is for Android 4.4.2:

Which we only have thanks to @Papay346.

Believe me, my head is spinning, too, re-visiting these old thread and trying to remember what little I can.
[G Pad 8.3 General] Bobberino:
I am so grateful for your help!!! And I feel so close yet so far/defeated on the errors I am getting with various LG flashtools mentioned in various threads. I'm hoping this picture helps me better explain what I am facing and hopefully some solutions.

From the instructions you linked in one of your replies, I get this error when trying to use the flash tool for the exact KDZ you mentioned success with:

I go to the menu to install tools as it instructs, it says install is successful, and then that alert pops up again. Manual install of the B2C gets hung up at 10%.

I even tried following some instructions in this thread to try and clear up the client setup error, but this ended up being even more stuff to download that led to nowhere as none of the flashtools worked:

I see almost everyone in L9 forum is giving reference link to this flashing guide in their threads, but almost no one is mentioning any credit to this. They are just putting links. What do you all think, pals? Do I deserve a credit or...

Any clue how to get rid of this error and get flashtools to work?
[G Pad 8.3 General] Bobberino:
And is it at all possible to flash a KDZ using this flash tool instead of the other provided?

This is the flash tool that is working for me-

I dragged KDZ in to the program instead of TOT just for demonstration purposes, I haven't tried to flash anything yet as I don't know what will happen:
