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.

Manual upgrading Nexus 6 without wiping data.

A little how-to on upgrading your nexus phone without having to wipe your data if you rooted and installed some stuff onto system partition.
WARNING!
DO NOT USE THIS METHOD IF YOU ARE NOT GOOD AT USING COMMAND LINE! THIS HAS A POSSIBILITY OF BRICKING YOUR PHONE TO WHERE IT WONT BOOT.
Note:
You will loose the following when using this method:
-Custom Recovery
-Custom Kernel
-ANYTHING that is installed on the system partition including but not limited to: SU (root), Busybox, Xposed, etc.
What is needed:
-ADB (1.0.32+) and Fastboot
-Factory Image of Nexus 6 (https://developers.google.com/android/nexus/images?hl=en)
-- MUST BE THE SAME BUILD VERSION AS YOUR CURRENT VERSION!
--- Check under System > About Phone > Build Number
Step 1 (Catch the update url):
Open up command prompt/terminal and type in
Code:
adb logcat
.
From here you will get a lot of debug lines, dont worry about any of it.
What we are looking for is the url to the update file.
When adb logcat is ready, start the update for your phone. (Dont worry about restarting or whatnot, you wont be using the file it's downloaded anyway).
From the url, use that to download the update file to your computer.
Step 2 (Backup):
This is important as a just in case **** happens thing.
BACK UP YOUR PHONE if you have a custom recovery.
Don't think that this update method is foolproof.
Don't even think.
BACK IT UP!
Step 3 (Restore to "Factory"):
This is where it gets hairy.
Using the factory image you downloaded open up the "image-shamu-<build>.zip" file and extract "boot.img", "recovery.img", and
"system.img".
Restart your phone to bootloader either with adb or pressing and holding power + vol down.
From here, in a command prompt/terminal, type:
Code:
fastboot flash boot <boot.img path>
Code:
fastboot flash recovery <recovery.img path>
Code:
fastboot flash system <system.img path>
System image will take the longest and will be streamed to the phone so just wait until it's finished.
Step 4 (Upgrade):
ok, now that we are in "Factory" settings, start up your phone in recovery mode.
From the recovery screen you should see the little android with the red exclamation point icon thing.
Press and hold power and click the volume up button. Release power button.
From here, select
Code:
apply update from ADB
now in command prompt type:
Code:
adb sideload <update.zip path>
Step 5: ???
Step 6: Profit!
I have done this method twice and haven't experienced any problems myself. As stated above, this does have the possibility of mucking something up so be sure to have backups.
After everything is done, you are using your phone in stock mode.
flash your custom recovery and custom kernel if you'd like. Also reinstall root via custom recovery (twrp will let you know) and busybox.
Troubleshooting:
- Update says system partition has unexpected contents.
-- Reflash system.img.
- Get adb sideload error (xxx)
-- Make sure you have the latest version of adb and that your drivers for your phone are installed. Sometimes you have to manually install the adb drivers when in sideload mode.

How to root the Honor 8: very clear steps for dummies

How to root the Honor 8: very clear steps for dummies​Requirements:
Unlocked Bootloader
Download TWRP and SuperSU
Make sure USB Debugging is turned on, in the developer’s options.
Download and install the correct drivers and ADB tools.
Watch the video once and then watch it again to make sure you get the flow or the work.
Once you have setup the device with your PC for ADB and fastboot connections we are ready to start.
Installing TWRP
Connect your device to your PC and make sure to grant authentication to your PC over ADB. (You should be able to see your device when you type [ADB devices] in the Command Prompt)
Type [adb reboot bootloader] and wait for the device to reboot into fastboot mode
Type [fastboot devices] to confirm you have a connection to your device
Make sure to save the downloaded recovery .img in the same folder as your are running Adb/fastboot tools, and then type [fastboot flash recovery TWRP image.IMG] ( replace .img with the exact name of the downloaded file)
When complete reboot normally
When the device comes back up, open up ADB and type [adb reboot recovery]
Your device should reboot into TWRP
Do not change to “read/write” keep in read only mode and do a backup
Once backup is complete then enable “read/write” by going to “mount” and disabling the option for read only
Rooting the device
While connected in recovery mode transfer the Supersu2.78 stable to your device and install it. After installed, reboot
After rooting your device may restart 2 to 3 times. This is normal so just be patient.
System will reboot and you should have root. Test root access with your favorite root app ( I like XDA labs)

On my honor 8 I also had to accept in my phone when typing the line fastboot bootloader , if I didn't the phone didn't connect
Also I had to manually pick the driver for the connected Honor 8 in device manager twice. There is a vid about this showing how to choose the correct driver manually (google inc.->the top selection I believe) but if u have no problem connecting in adb in the command prompt typing the commands never mind this.
Good u type where to extract the twrp - MANY MANUALS MISSED THIS took me 30 min to search the info uncessesarily. Just like no one mentioned I had to accept the first command in phone for me atleast.

Does it works for FRD L19 (64GB)?

Doesn't work for me the original recovery won't recognize adb device so here i have done this:
1) Flash a custom rom Oos based via twrp (i've done this with freedomos) DO NOT REBOOT phone after flash
2) Flash original OxygenOs firmware provided by oneplus site DO NOT REBOOT phone, not yet
3) Put original recovery in your sd card from your pc via twrp (if you don't already have it)
4) Install original recovery from twrp
5) After that, reboot to recovery and you should have the op original one, perform a factory reset via recovery
6) try starting device, if everything works you can finally re-lock bootloader (only if you want)

Yes this is the "defualt" method.. Mine was in case your PC won't recognize adb in stock recovery, because it happened at too many people for what i've seen on oneplus 3/3t/5

Hopefully i will get back to factory os with this method Thanks in advance bro helpful people like you keeping this community alive!

Help! I tried to do the sideload but in my powershell window says "loading: 'update.zip' *cannot read 'update.zip'* " I don't know what's the problem, my computer can detect my phone with "adb devices" and "fasboot devices" so that's not the problem

Reason for that is adb on Windows can't read large files as it's not Large Address Aware, I'll get the article I use that has a tool that enables that when I get home, it's basically a small program you need to run that enables that functionality.

Can't get adb to see my le pro in fastboot

My phone, the LeEco Le Pro 3 LEX727 ZL1_NA US model is on the latest EUI 5.8.021S. I am able to open the adb tools in command prompt and get my computer to recognize my phone with "adb devices", but when I go to the stock fastboot with the Chinese and English writing and use "fastboot devices" nothing shows up. I'm using the latest adb tools and am clueless as to what to do.

Unlock Bootloader - Le Eco Pro 3
If you are not seeing your phone ID in ADB
Did you enable enable Developer options, or chosen MTP?
Its possible that the Android driver driver is outdated, or just try another usb port, preferably in the back of the machine.
Go here to check a whole list of possible causes: https://appuals.com/android-phone-not-showing-up-on-pc/
More than you asked for:
Since you seem to be new to your Leeco phone and new to using custom roms, I am going to go ahead and answer your current question and provide you steps needed to move forward. No big deal, I just copy pasted my notes ( with a few edits)
First steps that you need to take:
1. You will first need to unlock the bootloader :
PHP:
https://forum.xda-developers.com/showpost.php?p=71566961&postcount=203
2. Install Twrp :
PHP:
https://twrp.me/leeco/leecolepro3.html
****** Scroll down to see: Fastboot Install Method (
3. Right now just use ADB. But for the future, I highly recommend that you buy an OTG drive: it makes the whole process a thousand times easier: They are cheap somewhere near $5 and worth ten times that
Unlocking the Bootloader
You can save your self alot of time by looking up how to give ADB system wide privileges: this will allow you to flash files without tying the directory path.
Mauronofrio created a tool called: "TOOL ALL IN ONE"" it's great, install it and check for updates.
PHP:
https://toolaio.tk
The all is one tool is excellent and you can use it to install everything if wanted.
I usually recommend it for novices that can use it to help with unlocking the bootloader and installing TWRP.
The tool will also update your copy of ADB, android Drivers and provide system wide privileges for ADB
LETS RECAP : Choose using the All in One Tool or the ADB Method
**********BEFORE DOING ANYTHING*******************
Make sure you have enabled the developer tools,
Turned on USB debugging
Authorized your computer on your device I.E: “MTP”
Make sure the All in One Tool can see your device
(*) Select your device from the drop down menu, then click check
(*) Choose to install drivers, and set ADB and fastboot privileges from advanced menu.
(*) First attempt to unlock, then check bootloader status
If you have a X727 you will need to flash : emmc_appsboot.mbn from this zip :
PHP:
https://androidfilehost.com/?fid=313042859668275431
Next, choose Recovery flasher and manually select your copy of TWRP
After you have received the success message, I recommend doing the rest of the install manually within Twrp Recovery.
(*) Reboot into TWRP and begin installation of your Rom, Gapps and Magisk.
Using the ADB Method
Install ADB/Fastboot tools on your computer
PHP:
https://wiki.lineageos.org/adb_fastboot_guide.html
1. Make sure you have enabled the developer tools,
2. Turned on USB debugging, and authorized your computer on your device “MTP”
3. Enter fastboot mode on phone (hold power and VOL -)
4. Make sure adb can see your device when you run "adb devices"
5. type: fastboot devices
6. fastboot flash aboot emmc_appsboot.mbn
7. Run { adb reboot bootloader } - No spaces (before/after)
8. Run { fastboot devices } to make sure you see your device
9. Run { fastboot oem unlock-go } to unlock your device temporarily
10. Run { fastboot oem device-info } to verify unlock status
11. Run { fastboot boot recovery_twrp-3.2.1-0-zl1.img }
12. 5. Reboot back to TWRP and begin installation of your Rom, Gapps and Magisk.
13. 6. If you wiped data, your device will now proceed to re-initialize itself as if from the factory
Concerning your device's storage,
When you boot into twrp you will see a message that states that the storage is encrypted.
*****************Important************************ ******************
Ensure that you have TWRP installed as the primary recovery
Ensure that you have TWRP installed as the primary recovery
Ensure that you have TWRP installed as the primary recovery
Ensure that you have TWRP installed as the primary recovery
To remove encryption you will need to format the storage
(Anyone who says otherwise has the X720 and not the X727)
You could also try to skip the formatting step. But you will very likely have permissions issues and get errors and you will eventually have to come back and format ( Again as long as Twrp recovery is install there is very slim chance of ever bricking your phone.
To format the storage
Go to Wipe, choose Format Data and follow the instructions.
This will erase all of photos , music, etc
If you wiped your data partition, you'll need to push the zip file to the newly formatted storage. - This is one BIG reason why using OTG is better. You can use Mauronofrio's "TOOL ALL IN ONE"" for pushing the ROM, Gapps, and Magisk to storage.
Root: You absolutely should root!
NOTE: If you have unlocked the bootloader and flashed TWRP to the recovery partition. But have not yet flashed a Custom Rom the OS will likely reset back to the factory recovery UNLESS YOU ROOT THE SYSTEM. Your device is still unlocked. But the recovery can be overwritten by the stock EUI system, so beware.
Installation of Rom, Gapps, Magisk
Boot into TWRP recovery
1. Go to "Wipe" and then to "Advanced Wipe".
2. Mark "Dalvik / ART Cache", "System", "Data" and "Cache".
3. "Swipe to Wipe" and proceed back the main menu.
4. Go to "Install".
5. Select the ROM zip file and then press "Add more Zips" and select the Gapps zip file, and then the Magisk file.
6. "Swipe to confirm Flash" and wait for some time.
7. After the flashing is finished, just reboot to system.
Finished!
If you need help or have a question message me, I would much rather help you with a successful install versus helping you unbrick your phone.

Thank you for your reply. I figured out the issue. Windows 10 updater wasn't auto installing the driver for some reason even though I have auto update ticked.

You have manually install those drivers usually.
Sent from my LEX720 using xda premium

I have the same issue in Windows 10. All In One Tool sees my x720 in adb mode, but when I switch to bootloader, the phone is gone. Device manager then shows unrecognized android device. I have LTSB version of Windows, so maybe that's why it won't auto install the needed driver. Could anyone point out what kind of driver exactly do I need, so that I can install it manually?
