I have an LG G PAD 8.3 VK810 Verizon that I am trying to root in order to SIM unlock from Verizon to ATT.

I have installed the Drivers packages here and it finds the drivers in USB Modes: Charge tablet and media sync fine, but when I go to Internet Connection mode and choose ethernet it can not find the following drivers: CDC ECM, CDC SERIAL, AND 3 THAT SAY LGE ANDROID PHONE.

Any ideas on how to get these drivers installed to try the next step? I tried to go ahead and run the iroot program but it can not find the device.

Thank you for the help.

I have installed a T-Mobile SIM card in my LG GPad 8.3 LTE so I could get the free gig of data they offer existing customers. It worked without rooting. All I did was add a new APN with the proper T-Mobile settings and I was able to surf. Did it right there at the T-Mobile store with the rep to verify it would work before I added the data line to my account.

Thx for the tip. The tablet is set to LTE mode and since T-Mobile LTE has the same band with Verizon LTE. It definitely works on T-Mobile.

For AT&T, no luck even if rooted. I used Radio Switcher app to go to the Tablet Info in Testing Mode. But it displays error message "This application does not work on this device".

Easy...

Vk810 supports lte bands 4(aws) and 13 (700mhz block c), bands that Verizon uses

T-Mobile uses band 4 for lte mainly, will use band 2 (1900) and 12 (700 MHz block a) in the future as well. Vk810 will work on T-Mobile wherever tmobile has LTE right now (with band 4)

Att uses band 4, 2 (1900), 17(700mhz block b) and 30(2300mhz). Vk810 will only work on att if at uses band 4. If att only used band 2 in your area, your att phone (which supports band 2) will show LTE, but vk810 won't work

I don't know if there is a map showing which bands att uses in your area. There is a spectrum map showing who owns which band in which region, but no guarantee that att has active cell sites

Trying to unlock

So, I got the VK810 and am trying to see if I can get data outside the US. This are some of the observations I made:

1. I got into the service menu, *#*#4636#*#* and tried to set the network band, but I a warning popped up sating that " This application does not work on this device" Possible fix is getting the testing menu from a lg g2. I am exploring the idea that it does not have GSM bands, only the LTE radios (This s a bit unlikely since LTE is a GSM technology, they would have had to go a bit far not to include GSM radios)

2. Tried editing the biuld.prop to force it to boot into WCDMA/GSM mode. No luck yet

Al this am doing on 4.2.2, if anyone has updated to kitkat, try accessing the service menu ( must download a dialer app from app store ) and set the network mode
[G Pad 8.3 Q&A, Help & Troubleshooting] paperWastage:
It is entirely possible for this device to only support the gsm 4g standard(aka LTE), and not the gsm 3G standard(HSDPA/hspa)

The modem chip might be capable of 3g/4g gsm, but lg could have excluded the necessary antennas/power amplifiers due to Verizon's request( cost cutting or desire to move to LTE data only support due to long term plan and Verizon not having a 3g gsm network. Since this device has no phone capability, might as well skip legacy support)

Also, Verizon would need to pay for FCC docs to document/test the wireless transmissions. Cheaper to avoid testing gsm I guess. In some cases (like nexus 4 LTE band 4), the hardware and software is fully capable, just not FCC approved. In other cases, no hardware or software support

Hi, so I have the same VK810 tablet...before updating to 4.4.2 the tablet was working great on t-mobile LTE however once I updated at first I didn't get any signal but once I inserted a verizon SIM into the machine and applied a few more updates that just released (i think) it then recognized my t-mobile SIM and showed me bars of service.

However even after updating the APN, I still get the activation incomplete message and when I turn wifi off, I get no service so I am stumped as well. I am considering swapping in a new SIM as maybe my SIM is too old or something

I am going to try the service menu item and re-check the APN settings. I even made sure to enable the roaming feature as the request of T-mobile tech support
[G Pad 8.3 Q&A, Help & Troubleshooting] theroblog.com:
Having some issues under Lollipop 5.0.2...putting in active VZW SIM then Tmo SIM makes it work. But then later it loses signal til you put the VZW SIM back in and swap again.

Trying some new APN settings (which should make no difference) but appear to be working better. Held signal for about an hour, then I put it in airplane mode and then back out and LTE came back. I deleted the old APN and made a new one. I also chose roaming on for data and automatic network selection.

5.0.2 isn't fully backed as it will give you a menu for WCDMA, GSM etc but all the options are greyed so it's really pointless.

Will report back if APN consistently works.

Having trouble using my T-Mobile Tablet Data SIM (1GB) on a recently purchased VK810.

I went through the process of using the LG Flash Tool to update from 23A to 24A (no probs), used Stump Root to root (no probs), installed TWRP 2.7.0.1 and flashed the 2.7.0.2 update (no probs), and installed CleanRom 1.0 (wanted KK + heavy debloat).

I'm able to connect to Wifi fine, and the first time I inserted my TMO SIM it detected that it was a TMO connection. After setting up my APN, I was able to browse the Play store and verified I was going through my LTE connection by going to ipchicken.com, which displayed a TMO IP and hostname. However, after rebooting the tablet, it can no longer connect to LTE. LTE Discovery detects the Band 4 connection, but it's reporting the carrier as "unknown", but oddly the MCC/MNC is still being reported as 310-260.

Another reboot didn't fix it. Factory reset via TWRP didn't fix it. A format and reinstall of CleanRom via TWRP didn't fix it. Stuck the SIM in another device and it's able to connect fine, so it doesn't seem to be a SIM issue.

Anyone have any ideas?

EDIT: Decided to re-flash the 24A kdz (starting from scratch). After installing it I skipped through the setup, turned the tablet off, insert my TMO SIM, turned it back on, and it connected! Set up the APN and was able to browse the internet again.

Rebooted the tablet just to make sure it would work after reboots... and it didn't. :/ When I try to look at the network or hardware info in the About Tablet menu, com.android.phone crashes.

Odd that it connects the first time, but can't connect after reboots until re-flashed is very odd...

EDIT2: Flashed 35A just to see how LP would fare. Same exact thing happened. About Tablet -> Network/Hardware Info isn't crashing though, and Status is displaying my SIM's phone number, but everything is still coming back No Service.

EDIT3: Reflashed 24A, same deal. I tried adding, deleting, re-adding, resetting APNs to factory default, etc. and none of that solved the problem after the reboot.

Guess I received a faulty tablet :/

Success! Flashing the 4.2.2 modem seems to have done the trick. Wish I knew about this the first time, would have saved me an entire day of messing around with flashing lol!

Basically what I did:

0. Did not insert SIM card yet. On microSD card: aboot.img (aboot4.2.2), modem.img (modem4.2.2), CleanRom's ZIP, Stumproot.apk

1. Flash the 24A kdz with LG Flash Tool 2014

2. Boot device, use File Manager to install Stump Root.

3. Root Stump Root, brute force mode, reboot when done.

(3.5. I connected to wifi and installed SuperSU from the market, but I don't think it was necessary)

4. Enabled USB debugging, copied aboot.img to /sdcard/, followed TWRP install instructions.

5. Boot into recovery, flash v2.7.0.2 TWRP update, reboot into recovery.

(5.5. Again, not sure if it was required, but I wanted to get rid of any dead files from the stock install, so I used TWRP to format the device, then rebooted back into recovery.)

6. Installed CleanRom and copied modem.img to /sdcard/ via TWRP.

7. Booted into CleanRom, enabled USB debugging, flashed modem.img via these instructions: http://xdaforums.com/showpost.php?p=54584896&postcount=5

8. Power off, stuck in SIM card, powered on.

9. Set up TMO APN, connected fine, visiting ipchicken.com showed a TMO IP/hostname.

10. Powered off, waited 10 minutes, powered on again, still connecting!

Hi

I am on stock rooted 35A

I am trying to unlock band 3 (more specifically 1800)for the device. My belief is that Verizon must have locked other bands when the device must support it at least.

If I try going into hidden menu, (install a dialer (Exdialer) from play store to dial *#*#4636*#*#). I do get to the menu. Everything works except Tablet Information

However, I end up with an error "This application does not work on this device" when I try tablet information but behind in grayscale I can see LTE /GSM/ RADIO etc.

When I tried "METHOD FROM g2" , I can execute the command and it worked for me, however, I can not find LTE bands or any such settings.

Another thing that I found using Titanium that there also exists a file named as "Verizonhiddenmenu".

Do you know if that could be accessed ?

Doing the following using Activity Launcher from the Play Store without having "installed" the hacked apk does nothing on my G Pad, but maybe it'll be different for yours with the hacked one?

I have experience with both the LG Hidden Menu and the Verizon Hidden Menu on both the VK810 and the LG G3 (VS985).

On the VS985, com.lge.VerizonHiddenMenu.VzwLTETest.LTEBandSelection gives you the list of bands the phone supports, and allows you to turn on LTE Band 3 and Band 7.

That submenu does not exist on the VK810. Additionally, looking up the FCC documents for the VK810 show only Bands 4 and 13 being tested, whereas other bands were tested on the VS985.

The VK810 does not have GSM radios either. Under com.android.settings.SystemSelect, no matter what settings are set (Global, GSM/UTMS), the connection will not change and will still be connected to LTE only. Verified by using a T-Mobile SIM in the VK810. Able to connect to Band 4 LTE, but no matter how much I mess with the system settings, there is no way to turn on GSM.

Additionally, com.lge.hiddenmenu.kddi_only.NetworkMode allows me to select between various combinations of LTE, GSM, WCDMA, and CDMA, but the only options that actually stick are only the ones that include LTE. Setting to "LTE/GSM/WCDMA" sticks, but checking my connection via LTE Discovery and SignalCheck only show LTE connections.

Suffice to say, the VK810 only has LTE, and only on Bands 4 and 13.
