[GUIDE]LG G Pad 8.3 GPE (V510)(ROOT)(Recovery)(4.4.4 Sideload)(ROM)(GENERAL INFO)

How to Unlock, Root, Update, Install Custom Recovery, and ROM your LG G Pad 8.3 GPE (V510) ​
First off if you aren't already familiar with ADB and FASTBOOT, please take some time and read over this post (thanks @ricky310711 ).
----------------------------------------------------------------------------------------------------------------------------------------------------------------------
Drivers
Windows 7 -- MTP Installs automatically, ADB Bridge requires Google USB Driver
Windows XP -- MTP needs LG Drivers, ADB Bridge requires Google USB Driver
LG United Mobile Driver (from G2) -- Will install drivers to access G-Pad as MTP device
Google USB Debug Driver
Installing ADB Drivers
Windows
Right click on the device with the triangle (Probably named "LG V510") in device manager
Choose "Update Driver"
Choose "Browse My Computer for driver software"
Locate where the Google USB drivers extracted with the "Browse" button
Choose "Next"
You computer should pick the drivers up and install
Linux (Thanks @sleekmason )
This guide assumes you are in root for the commands, and have a basic understanding of the terminal. Use sudo if you wish. Part of this comes from this guide: http://avedo.net/773/install-adb-and-fastboot-under-linux/ part from this guide: http://bernaerts.dyndns.org/linux/75-debian/280-debian-wheezy-android-tools-adb-fastboot-qtadb and partly from this forum. I'm using i386 AntiX (debian pure), if you are using amd/64 bit you will need some dependencies:
Code:
dpkg --add-architecture i386
Code:
apt-get update ; apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
you will need to go into developer options to enable debugging on your device.
You will need to create the udev rules for your phone on your computer. use "lsusb" to find the manufactures code. it will show up as a nexus 4 device...interesting.
Create a folder /etc/udev/rules.d/99-android.rules you can use gedit if you like:
Code:
gedit /etc/udev/rules.d/99-android.rules
Put this inside and save, changing the manufactures code as neccesary, and changing "your-login" to your login name.
Code:
# Google Nexus devices
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666", OWNER="your-login" # Google Nexus devices
## restart udev## #
Code:
service udev restart
I'm keeping this simple, so here we go! Use the above links as reference as neccesary.
1.
Code:
apt-get purge android-tools-adb android-tools-fastboot
##You shouldn't use adb from the repositories##
2. Down load the latest adb bundle from here: http://developer.android.com/sdk/index.html
3.
Code:
unzip adt-bundle-linux-x86-20131030.zip
4.
Code:
mv adt-bundle-linux-x86-20131030 /opt/android-sdk-linux-x86-20131030
## (other google products reside here. Also, this takes a minute or so on slow machines)##
5.
Code:
ln -s /opt/android-sdk-linux-x86-20131030/sdk/platform-tools/adb /usr/bin
##(this links to /usr/bin to make life easy)##
6.
Code:
ln -s /opt/android-sdk-linux-x86-20131030/sdk/platform-tools/fastboot /usr/bin

Can you post a system dump and kernel please?

In step 5 of "How to Unlock Your Bootloader", I suppose it should be "fastboot oem unlock" instead of fastboot oem-unlock". Newbies may get stuck right there.

you are correct, yes. there is no hyphen between oem and unlock.

Can't install LG USB Drivers
I have V-510. I went to LG's website and downloaded their mobile suite and when I click on the "install usb driver" I get a list of carriers and I choose USA/LGV500 and then install the driver but once I connect the pad with USB debugging enabled and I get a message that the driver wasn't installed.
Can someone post a link for the usb driver?

I got my replacement GPE. Followed instructions here and have the GPE rooted and the boot loader unlocked thanks to directions here. After doing the OEM unlock it pays to be patient and count to 30 or something and let the tablet completely reboot. I also let it update to 4.4.2 first.
Now we need the ElementalX kernel .
Thanks for the guide and support.

Still having problem with having my windows 7 install the driver when I turn the USB debug on. There are 2 locations under device manager showing V510, one is the portable device with properly installed driver from MS and the other under other devices with yellow triangle and no driver could be found status for that. Any clue how to fix that?

Try deleting the driver with the triangle, then reboot, plug in the G Pad and see if it will reinstall properly.

I have tried a few different drivers with no success. I have an HTC phone that works fine but ADB does not see the Q Pad. It has to be a driver issue. I have installed/uninstalled them multiple times with no success. I even uninstalled the HTC drivers to see if that was the problem, nope...
Ever tried multiple usb cables (ones I know work) and tried every USB port on my laptop, nothing!

The driver with the triangle is probably the ADB Composite bridge. Download the Google USB Driver and install it. Then
Right click on the device with the triangle in device manager
Choose "Update Driver"
Choose "Browse My Computer for driver software"
Locate where the Google USB drivers extracted with the "Browse" button
Choose "Next"
You computer should pick the drivers up and install

Bingo! Thank You!

This worked thank you.
However, I am still unable to root the device. I even tried the Kingo root but it failed. I must have messed with my device a lot. Willl try to factory reset

I successfully unlocked the bootloader and rooted. Installed customer recovery as well but do not know how to boot to recovery. On my Galaxy S3 I used to go to custom recovery by holding the power which gives me the option to boot to recovery
Thank you everyone for the help.

I use quick boot from the play store to boot to recovery or you can power off and hold the power and volume down after powering off and select boot to recovery.

After sideloading the V510 stock rom, will the LG G Pad will show V510 and get regular updates OTA as LG G Pad Google play edition?

No. The GPE firmware from the 510 isn't compatible with the 500.

Windows 10 laptop can't detect softbricked Nexus 4, TWRP, no OS

I've checked other threads but other similar threads were able to get the phone detected in Device Manager so...
I went to factory reset my old Nexus 4 after using it whilst my LG G4 was being repaired. Instead of wiping the data, I accidentally wiped the entire phone, OS included. I wasn't paying attention to what i was doing due to working at the same time and as a result the phone now only boots into TWRP and fastboot mode, but nothing else.
I tried to connect it to my windows 10 laptop so I could flash a new ROM but my laptop can't find the nexus 4 at all. Not when in recovery or when in fastboot.
Opening device manager shows that it is not there at all. There is no ACER usb device driver, nothing that resembles the nexus 4 at all. I've attached an image showing what device manager shows when the nexus 4 is connected and in recovery mode.
As you can see, there are no drivers I can uninstall. I have installed the google USB drivers from Android SDK manager. Still doesn't show. ADB doesn't work either.
I have tried multiple USB cables and every USB port. The phone charges when using an AC adaptor and charges when connected to the laptop. I can't try a different computer because I do not have access to one. Frankly I'm at a loss as to what to do.
When my nexus 4 was previously unable to connect I was able to see the device and just had to uninstall/reinstall/update drivers to get it working. This time, I can't seem to do anything. My LG G4 connects fine and without issue.
Anyone able to help?

The only way to really tell if it is a software or hardware issue would be to try another computer with Win7.
You may be able to flash a custom ROM with a OTG drive as well.

I had the same problem. When using adb and fastboot I get errors about like "error: device '(null)' not found".
Youtube video with id t0pV2pSw2N0 (sorry I am not yet allowed to post external urls) was helpfull and now I can see Android Composite ADB Interface again in the device manager. I still can not use commands adb and fastboot with exception of adb sideload. Unfortunately I have not yet succeeded to flash an image succesfully with sideload.

first try 2 remove any current drivers that are installed.
then u should experiment with different drivers.
the SkipSoft ToolKit have a huge selection, try each one of them (one of them should work).
begin with the ULTIMATE drivers and Adb/Fastboot Installer and if it don't work use the toolkit drivers.

For me it turned out that MTP was enabled by default. After each restart MTP was enabled again. Now I have disabled MTP and my device is found by normal adb command.
Steps:
1) Start your device in twrp recovery mode
2) In main menu go to mount and tap "Disable MTP"
3) In main menu go to advanced -> adb sideload. Wipe caches and slide to start sideload
4) On your pc go to the command shell
5) Start "adb sideload <image_name.zip>" (replace image_name.zip with a valid image). It does not matter whether this fails or succeeds. Only thing important is that adb connects to your device.
6) Start "adb shell getprop persist.sys.usb.config". As result you will see the actual setting of the USB configuration your device when starting up. In my case it responded with "mtp,adb".
7) Start "adb shell setprop persist.sys.usb.config adb" to enable only "adb" configuration
8) Repeat step 6 to check result
9) Restart your device in recovery mode
10) Start "adb devices" to check if your device is now listed.

I tried removing all USB drivers and then using the toolkit and tried installing each driver. None of them allowed my PC to detect the nexus 4. As you can see in the attachment, nothing in device manager remotely resembling my nexus 4. This is after uninstalling and reinstalling and also updateing the LG G4 drivers (it makes no difference).

Unfortunately I don't have access to any other PC for this purpose. I can't connect download software or connect USB devices to the PCs at work due to security. I tried an OTG drive but TWRP wouldn't let me mount it, apparently OTG is not enabled by default for the nexus 4.
I've tried all 3 USB ports, several different cables but no luck. I guess that's it for this nexus 4 then?

If the phone is not booted into its ROM, ADB commands won't work. You need to use "fastboot devices" with the phone in bootloader mode.

You android device will reboot in several different boot modes (fastboot, recovery, normal). For each of these boot modes a separate device drive might be installed on your Windows. So check the device drive after each change of boot mode. If needed uninstall and reinstall the correct device driver.

[Solved] Stuck in Fastboot, USB does not connect

Hi.
I need help. I already checked any relating topics on this and other boards, but I couldn't find any help.
I tried to flash TWRP Recovery with the "All-In-One-Tool", but as soon as the phone entered fastboot-mode it couldn't be recognized by the system anymore.
Error Code 43. (USB\DEVICE_DESCRIPTOR_FAILURE)
I am running a Windows 10 Machine.
Solutions I already tried:
- using different drivers (lenovo v1.1.16, zuk v1.0.8, latest google usb drivers from sdk)
- with deactivated driver-signing-check (or what it is called)
- different adb, fastboot tools (mini adb, etc.)
- running live cd of FWUI (forget windows use linux)
- using different usb ports on my pc
Additional to that, my power-button isn't working anymore (since a few weeks now) and I have no idea how to reboot my phone.
I would really appreciate your help.

Follow these steps to install twrp in easy manner:
1.Firstly install lenovo usb drivers.( look download one at bottom of this post for files)
2.Then Go to the adb driver folder and do install necessary set ups according to your system(64 bit or 32 bit).
3.Now go back and move to AndroidSDKSlim\android-sdk-windows\platform-tools folder (put on your phone into bootloader mode and connect usb).
4.Type fastboot -i 0x2b4c devices in cmd and see if there is a reply.If you got reply It means that your drivers are properly installed otherwise not.
5.Once you get reply type fastboot -i 0x2b4c flash recovery twrp_recovery.img
6.After flashing done Disconnect USB then go to the recovery mode and that's it you will see twrp installed as successfully.
(To boot your Device into recovery mode, just turn your device off and then press and hold volume down and power keys at the same time)
Note: It worked for me in windows 10(64 bit).Don't disconnect Usb from your PC while flashing Twrp.
Download:Because xda won't allowing me to put download links up to 10 posts as i'm new So give your email in reply i will send files to that email.
thank you.

Problem solved. I don't know the exact solution.
I waited until the battery was empty and recharged it, phone was booting normal. I installed another set of lenovo driver on my pc and gave it a shot. This time the device got recognized by windows and i was able to unlock the bootloader and flash the recovery.

Same here, I'm desperately trying to unlock the bootloader. On Windows 10 adb correctly recognize my Z1, but when I reboot in fastboot mode I can't get past the "<waiting for device>" message.
Could you please send a download link to [email protected]?
Thanks a lot!

SOLVED - Fastboot with no adb - any help?

Hi,
rooted 2017 16GB ShieldTV.
Unlocked bootloader.
TWRP was not installed just used to boot once and installed SuperSU (I feel like an idiot learning this only after)
Played with it - removed some critical system apps, and also managed to disable USB debugging (this only as I thought that TWRP was installed - and felt safe to do ANYTHING)
Now - boot to fastboot happens, but there is no adb.
Any saving method?
Original recovery gives options to ADB sideload and USB update.
Tried to use this by putting official Nvidia stock image on USB and but it reports signature failed, and refuses to flash.
Any help?
Thanks guys

SOLVED
Writting this as soon as I could cool down.
Situation:
- Shield ATV 16GB 2017. SW Nougat 5.2
- Unlocked bootloader (every boot gives that safety warning)
- System bootloop on Android circles animation (managed to root it previously and removed some critical apps by mistake)
- NO USB debugging
- NO custom recovery (as process for rooting only used TWRP to flash SuperSU, nothing else)
- Entering fastboot possible only by hardware method (controller connected by USB, hold A+B buttons while Shield is plugged off 10sec, then plug Shield in. Two short vibrations of controller and fastboot screen appears.)
However - NO adb in fastboot. (pinging with adb devices gives NO response). Only option that works is entering official recovery which gives options for adb sideload or update from USB. However - no zip file is accepted due signature check (and I tried tons of them)
Tools
1. Windroid
https://forum.xda-developers.com/showthread.php?t=2499926
2. Proper TWRP build
http://nvidiashieldzone.com/download/twrp-3-1-1-1-shield-tv/
3. Custom flashable rom (I used Lineage OS for Shield - lite and without Gapps - to speed up booting into environment that works). Put it onto USB drive
4. Oficial Nvidia recovery image (https://developer.nvidia.com/shield-open-source)
5. Minimal ADB and Fastboot (http://nvidiashieldzone.com/download/minimal-adb-and-fastboot/)
6. Nvidia controller plugged into USB port next to HDMI
7. Male-to-male USB cable (for ADB)
8. USB mouse
Process
1. Start Windroid and choose device (Nvidia, Shield TV)
Windroid will automatically download resources in Data folder (incl. TWRP that did not work for me), so dont block it with firewall.
2. Download proper TWRP from link above, and replace the one in Windroid Data/Recoveries folder using same name (Recovery1.img). You will notice difference in sizes. One that Windroid downloads is 25mb, while the one from link is ~ 16mb.
3. Enter fastboot on ShieldTV using hardware method (above mentioned with A+B buttons)
4. Now quickly In Windroid click button Refresh - and status will be updated to Fastboot
5. Then again in Windroid - click Flash TWRP and accept safety questions.
6. After successful flash - reboot into TWRP (here you need USB mouse - so you can unplug Nvidia controller, and plug mouse)
7. In TWRP - Choose Install - navigate to external USB and select flashable zip (Lineage ROM as above)
8. Once booted - enable USB debugging again. (you could be prompted on the Shield TV to allow your PC as debugging device, if so, say yes)
Getting back to full stock ROM with TWRP and unlocked bootloader
1. Install Minimal ADB and Fastboot you downloaded
2. Extract boot.img, system.img and vendor.img from Nvidia stock recovery image (leave other files out), and place these files into Minimal ADB and Fastboot folder (it is in Program Files x86)
3. While on (in LineageOS) connect Shield TV with PC using male-to-male USB cable
4. Start Minimal ADB from destkop icon and run following commands (commands are only in italic)
adb devices (checks if device is online. Its a must to proceed)
adb reboot bootloader (reboots to fastboot)
fastboot flash boot boot.img
fastboot flash system system.img (will take longer as its a big file)
fastboot flash vendor vendor.img
Once finished - reboot to TWRP, plug in USB mouse (instead of controller) to navigate, and perform Factory Reset.
If you wish to root you can do it via TWRP (which is what I did, flashing SuperSU previosly downloaded to USB)
Thats it - you are back from the dead!

Post updated - with process how to go back to stock

Thanks for this guide. It saved my ass!

Hi phnikola
thank you very much for your super instructions.
With this tool I could bring my TV Shield 2017 back to life, which got stuck in the Boot Animation.
I thought it was a trash can case, also contacted NVIDIA support to see what they were saying.
So I can also send the possible to me for the purpose of repair saved, thanks to you!!!!!!!!!!!!!!!!!!
Greetings Akki

Help installing TWRP? (T330NU)

Hey gang - this has been a bigger challenge than on any of my other devices, it's weird.
I've DLed both the TAR and IMG versions of TWRP.
Reboot to recovery, try to flash the TAR with Odin... it thinks about it for about 90 seconds and then tell me "FAILED!" Meanwhile, on the Tab screen, the little progress bar starts... but then nothing happens after that.
So I figure I'll use ADB/Fastboot to flash the IMG. So. Booted into the OS, USB Debugging on... connected to my W10 box > Command Prompt, I type "ADB devices."
[Hex code for Tab] - unauthorized
I unplug / replug and get the popup "Authorize USB debugging?" on the Tab. [OK]
ADB devices gives me [hex] - device
Fastboot devices doesn't show anything.
OK. ADB reboot recovery
Now in recovery mode.
ADB devices... -> nothing
Fastboot devices... -> nothing
Why does it show up in teh OS but not in recovery? And why does ADB work but not Fastboot in the OS?
Maddening. Help?

Quick follow-up. Got it installed.
I tried a different computer, and downloaded Odin 3.12 to that vs. 3.10 on my main computer. Not sure which of these changes was responsible but I was able to flash TWRP without issue.
