My "[VK810.4G] [altev] most reliable way to root and install a custom recovery" stickied thread in my signature below has a link to the TWRP v2.8.7.0 thread that's in one of these sections. You don't need TWRP v2.7.0.2. 2.7.0.1 to initially get TWRP on there, and then update to 2.8.7.0 from 2.7.0.1.

If either of *those* two versions of TWRP's links are bad, let me know here.

Edit: I just checked and the 2.7.0.1 and 2.8.7.0 links are both to Android File Host, so they're reliable and they both load just fine for me.

just now put TWRP on my 2+ yr old tablet. Thanks so much
[G Pad 8.3 Original Android Development] ouellettesr:
I recently got a altev gpad. Is there a specific twrp I should be using? I installed the latest twrp, but it doesnt seem to work properly. For example, I cannot mount the sd card. I have downgraded to 4.2.2 with LG Flash tool 2014, and installed the initial twrp with adb. then I used twrp manager to upgrade to the latest TWRP. I have been having serious issues with drivers. Being that its so old, im not sure if I should be using the latest version of twrp or an older one. I have a feeling that the new version of twrp is the reason for my SD card problems but I cannot be sure.

Also I thought that the altev was the google edition, the v510, is this correct? If so, the TWRP manager wont download anything for this setting, only the v500. Could someone help me understand whats going on? Ive scoured the internet for answers.

What I would like is to have twrp as my recovery and have LineageOS installed afterwards, which after looking on their page, says for the v500, I dont know if this is compatible with my altev vk810.

Im running windows 10 64 bit. Im guessing this is the reason for my trouble with the drivers. Do I use the latest whql lg driver? 4.2.0, or an older version?

thanks in advance.
[G Pad 8.3 Original Android Development] roirraW "edor" ehT:
Don't use TWRP Manager unless you can find the VK810 on there. The altev is the VK810, not V500 or V510. Use the TWRP v2.8.7.0 from step 0 in the instructions to flash from my thread here. https://xdaforums.com/showthread.php?t=3113607. It's not my TWRP but it's a known good one. I know I've tried some newer than that and they had one problem or another, but since my VK810 is broken I don't know if any newer than that work 100%, plus it's been so long that I can't remember if I ever found one newer than that which did work 100%.

Nothing for the other variants is compatible with this variant. I have another link in my signature below for how to root, etc, that gives the info about drivers.

I never had a problem on 10 x64. Always go directly to the manufacturer's (LG) website for the latest drivers.

Hello, I'm curious as the to if this new recovery can be flashed using the Flashify app from play store?
[G Pad 8.3 Original Android Development] ibawanzingee:
Probably not, and I wouldn't take the chance. This is a very different and specific method for flashing a recovery, because of Loki.

[G Pad 8.3 Original Android Development] RPelham:
Hey everyone,

I just took advantage of a deal with Verizon to get a free tablet with purchase of a phone. Well.. I've never worked with LG before (unless you count the Nexus, but I don't). I have experience with Samsung, HTC, Nexus 5 and Kindle. All of which I was able to get to connect to ADB.

This VK810 has me absolutely stumped. I enabled USB debugging mode and I installed Verizon's drivers that came with it to no avail. I installed LG's VK810 drivers to no avail. I downloaded the x86 version of the SDK and the x64.

Everytime I query "adb devices" I get an empty list. Can someone tell me if there is some sort of trick that I happen to be missing? I would love to get TWRP installed, but can't if I have no access to ADB. If it matters, which it may, I am running Windows 8.1. Could that have something to do with it?

Thanks,

RPelham

P.S. I am using the original cable that came with the device. Thanks!

that can certianly be done, but can you link me to the kernel source you are using??

the error:

https://github.com/ngvincent/android_kernel_lge_vk810.git

proprietary libs (copied from v500), use branch kk-4.4

wondering whether I should pull out the stuff common to both v500 and vk810

https://github.com/ngvincent/vendor_lge.git

DrGravy probably built the current TWRP using lg's released source

however, lg's source might not be good enough for a TWRP/cm build

(someone can chime in with a better view, or correct me if i'm mistaken)

lg (or their oem partner) starts with a basic kernel source, typically from (Qualcomm's) reference board design.

https://www.codeaurora.org/xwiki/bin/QAEP/release

Note the tag/build IDs on this website. sometimes, OEMs start with a really old tag because their other devices use that tag too, or they started 6months ago and never bordered to pull in the new changes.

LG/oem partner add necessary changes (eg if the basic source doesn't include support for pm8921 battery charger and this device uses pm8921, they add it)

when LG/oem release sources, they only give us a "snapshot" of the current files, instead of providing the entire git source code history.

cm/twrp might be using a "newer" kernel source with extra features( like ext4/selinux support), that the OEM source might not have. therefore, someone brings up the device for a cm build, they have to pick off bits and pieces from the LG source and integrate it with whatever kernel they are using. i'm not an expert on this step, more of a person who likes to tinker with other people's work for now

Hey do you happen to have the stock recovery img? I mean I have the stock aboot but not relay sure how the loki patch recovery works. Would like to have in case I would go back to get ota update(if there ever is any). I am also guessing it would need to be loki patched to push because of the locked bootloader. If you could posibly shed some light on how we would go about to go back to stock recovery that would be awesome. Thank You.
[G Pad 8.3 Original Android Development] Drgravy:
sure get it here: http://goo.gl/cmrBwV

shouldn't need to loki patch it

just copy it to your internal storage and flash with dd

open your terminal on your pc enter the following commands

adb shell

su

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

exit

exit

just make sure the commands are exactly right

My home Internet has crapped out and I need to get data working on the VK810, so unfortunately need to revert to stock for a bit since data isn't working on this port of CM11 yet. However, tried the above and get the following:

/dev/block/platform/msm_sdcc.1/by-name/recovery: cannot open for write: Permission denied

Edit: interestingly, I was able to run this from the device itself with a Terminal Emulator, but it doesn't seem to restore the stock image, even after a reboot. Is that not the intent of these commands?
[G Pad 8.3 Original Android Development] paperWastage:
Nope. Those commands are for restoring stock recovery instead of having the custom TWRP recovery. Stock recovery is required when applying an ota update ( which probably will never show up from Verizon)

To restore the stock ROM: remember how you are supposed to backup inside twrp before flashing cm11? Go back to twrp (you might need to reflash twrp since thode commands restored stick recovery ) and restore from that backup. Stock ROM will be restored and usable

(but recovery is still TWRP. If you want full stock ROM and stock recovery , then restore from the backup AND follow the DD instructions you quoted )
[G Pad 8.3 Original Android Development] rant:
Thanks. I did eventually figure out that this isn't the stock ROM, just recovery. And stupid me, no backup before flashing CM11. Oops, guess I'll make do until we see a ROM with LTE support or a stock ROM, nothing on LG's site but the open source files.
[G Pad 8.3 Original Android Development] rkmFL:
I'm having an identical issue to an earlier user. That user had not originally assumed root (run "su"). In my case I've tried everything but can't get su to take, based on the instructions here.

Here are my details:

-------------------

* G Pad 8.3 Model# VK810 (Verizon VZW)

* Running 4.2.2(JDQ39B) - I have not accepted any OTA updates

* USB Debugging Enabled, USB > Internet > Ethernet Connection Enabled

* Successfully connects and shows devices with the ADB DEVICES command

-------------------

I have no problem with any of the adb commands, I am able to push both files, change permissions, etc.

The only thing I cannot do is invoke SU, I get:

/system/bin/sh: su: not found

Because I don't have superuser privileges, I then get this error when attempting to run the loki_flash:

./loki_flash recovery /data/local/tmp/twrp.lok

[+] loki_flash v2.1

[-] Failed to open aboot for reading.

All adb commands are working great, I can move around directories, etc. I just can't run su.

Thank you in advance for any insight!

rkmFL
[G Pad 8.3 Original Android Development] Drgravy:
are you sure you are rooted?

you could check with root checker

also after the su command you will have to accept the su dialog on the device

** also you can run the same commands from your device through terminal emulator minus the "adb shell" of course
[G Pad 8.3 Original Android Development] rkmFL:
Thank you for the reply. Sometimes I wonder how I wake up in the morning, what a dumb move on my part..

You're right. I was assuming the loki flash stuff was to obtain root.

I have not found any rooting options for the VK810 and believed this was the hack to overcome that, flash a recovery, then flash a root from the recovery.

The only two rooting options I've found (ioRoot & EasyRoot), either appears to work with the VK810, and I don't see anything else on XDA or Google.

How did everyone else on the VZW VK810 get root?

Thank you in advance!

Also, [MENTION=5037444]Chance77[/MENTION], thanks for the note that Kingo works. I've had so many problems getting Kingo to work in the past (the app won't actually do anything if they don't get a response from their servers in China doing a phone-home immediately upon running). I must have wasted three days trying to root my VZW Note 3 with Kingo, only to eventually learn their servers were down and when the app didn't get a reply from their servers, it would just sit there claiming it couldn't connect to the phone (despite ADB working fine, etc).

On a separate note, I have a Google 10, a Google 7 (v2), and a Note 3, and this G-Pad tablet is my preferred device, by far. I love this thing; would love it just a bit more if it had ROM's being ported, but hey, I knew that going in. Couldn't be happier with it, and I'm shocked at how good LG's stock keyboard works; I've continued using it despite being a licensed Swype user.
