Do an emergency software recovery with lg bridge on mac or windows or go to the nougat root guide and use lgup to flash 10f firmware and root it correctly. You can definitely fix it. Dont worry
[LG G Pad X 8.0 Guides, News, & Discussion] jcgordon10:
Thank you so much. Glad to hear there's a way to fix it. If I to proceed with trying to root it properly by flashing the 10f firmware to it, do I just do that the same way in lgup? Do I need to alter anything to be able to flash it properly? I'm a little hazy on the process after reading through all the little different things people have done, and I want to make sure I know what I'm doing.
[LG G Pad X 8.0 Guides, News, & Discussion] jcgordon10:
So I finally got it all to work! I flashed the 20f firmware, followed the dirtycow exploit, got twrp working on the tablet, and from there I was able to instal LineageOS 14.1. I have realized that I don't currently have root access on the tablet though. Was root access only a temporary thing? Is it important to get at this point?

THe other big problem I've encountered now is not being able to use my External SD card for storage. Google prompted me about it when I began, and I tried several times to follow their prompts to use my external sd card as internal storage, but it seemed to fail each time, and now it won't even recognize it if I pop the card in or out. It's not detecting the storage. I don't know if this is something I can fix in twrp or what?
[LG G Pad X 8.0 Guides, News, & Discussion] Stonkers:
Dont know about the sd. It should work fine unless theres a problem with the card itself. If youre going to format it as imternal id probably get a class 10 or class 3 sd. I also recommend using apps2sd and partitioning it that way instead of using the system format. When i was on lineage i didnt have that problem.

I also recommend resurrection remix. Its vert stable and Its more customizable in general and has oms support for substratum.

For root you have to manually flash magisk, super su or lineage su.

Happy to hear you got it working?

Has anyone tried to do these steps with the 522 variant but without bootloader unlock? What happens?
[LG G Pad X 8.0 Guides, News, & Discussion] Stonkers:
Either nothing or a possible brick. The bootloader has to be unlocked to flash a custom recovery.

Hey guys, I been reading, and have a question;

I bought 1 of these used, and of course FRP is enabled. I downgraded it to "i", using LGUP, but it is still locked. What's the easiest way to remov this so I can get root and TRWP? I am just using this for my home automation, so i wanna get rid of the bloatware and use it like a remote..thx
[LG G Pad X 8.0 Guides, News, & Discussion] Stonkers:
Thats a tough one. Youre gonna have to search online for different bypass methods and find one that works. It probably wouldnt hurt to downgrade as low as possible. 20f is the only one that can be rooted on nougat but usb debug has to be checked.

Im not sure but i dont think u can downgrade to mm cause of antirollback. F works though.
[LG G Pad X 8.0 Guides, News, & Discussion] .fenrir:
You'll need to downgrade to 20f if you want to root on Nougat and follow the Nougat root guide at https://xdaforums.com/g-pad-x-80/how-to/nougat-7-0-v521-guide-to-update-v521-lg-t3533338 . Otherwise you can follow the guide here to go all the way down to 20c and go back to Marshmallow.

Fortunately LG/T-Mobile haven't done anything on this device to prevent downgrading so using LGUP you can downgrade to any of the older versions using the kdz files. That being said most people are better of sticking with 20c, 20f, or whatever the newest version is (20k at this time), since root was only achieved on 20c with a modified kdz here and using dirtycow on 20f which was patched on Android in later versions.

how do i unlock the bootloader if i dont have access to tablet?

---------- Post added at 04:51 PM ---------- Previous post was at 04:51 PM ----------

Need bootloader access, correct?
[LG G Pad X 8.0 Guides, News, & Discussion] yellaboyla:
FRP ie. Google account verification

OK. To help other people going through this nightmare that Google has created, here is what I have learned;

It seems like with the update to Android 7, most of the tricks on the internet don't work.

1. Getting to the internet serves no purpose as you can not download any files to the phone or tablet

2. Disabling Google play services and the Setup wizard does not work, as Google has created some short of loop to keep you from getting to the desktop. Actually,it pushes back to the beginning of setup.

3. You can not downgrade any further than 20f that I have found with LGUP.

4. You need access to the phone in order to modify the bootloader, thus loading a new ROM.

5. Getting to settings is easy, but adding a second Google account is not allowed and kicks you out.

So here is were we are left. We need to load a fresh ROM with no setup wizard, or add a new Google acct.

SO, keep you posted.........
[LG G Pad X 8.0 Guides, News, & Discussion] yellaboyla:
As promised, I have bypassed Goolge's FRP / Account Verification / blah blah blah :o

It was no easy task, as the info out on the net is misleading, incorrect, and blatantly false. You guys are my heros, as I have learned so much here. I will do my best to help anyone that was/is in my position. Here is a very brief synapse;

1. Have to roll tablet back to 20F. Use LGUP and UPPERCUT. (My anti-virus lit up on uppercut- be aware) When you finish, your secuity level should be November 2016.

2. Once back, then you will need to get 2 files, Shortcut Master Lite and Sidebar Lite.

3. Once you reboot, you need to get into settings. There are a ton of tutorials on how to turn on the accessibility wizard. Once on, you need to go to settings. Anything else won't work.

4. You then need to kill a few apps. (all google apps under apps/system and the 2 setup wizard apps)

5. Before installing, u have to turn on unknown sources. Then u in business.

6. The tricky part is crashing the setup wizard which took me a few tries, but it does work.

I will post the videos, but like I said, I just jumped around until I peaced it together. I will respond to anyone needing direction!!

Now on to root and roms!!!

boot img needed

Can someone attach V521 stock boot img for me ?

And if you have magisk installed, also attach the patched boot img for me .

I upgrade magisk 18 to latest and now it keep bootloop at power on and Tmobile logo. I can get into fastboot/twrp recover, trying to flash stock or magisk 18 patched boot img

Thanks
[LG G Pad X 8.0 Guides, News, & Discussion] googlephoneFKLenAsh:
You can not use later versions of magisk than v16.7 if your v521's firmware version is newer than 20f.

Just flash magisk uninstaller zip in twrp, which will revert to stock boot img. You can then backup stock boot img in twrp and/or flash compatible magisk version.
[LG G Pad X 8.0 Guides, News, & Discussion] abced123:
I just flashed the uninstaller, it said succesfully, found stock boot img and remove magisk files, etc. but device still bootloop at the LG logo . Any idea ? TIA

[LG G Pad X 8.0 Guides, News, & Discussion] roirraW "edor" ehT:
First you need an unlocked bootloader, so you have to find out if you have one or if it's unlockable. The T-Mobile devices are all unlockable. Then you need a stock V522 update KDZ. Without both of those things, the method implemented for the V521 won't work.

so I have a bit of an issue,

while I was running flashify I accidently flashed twrp over the boot.img, so now the tablet doesn't allow me to boot into the OS.

I tried a factory reset, and advanced format and that did nothing, you can't flash in fastboot, twrp is fully functional though.

Now it says there is no OS, when you plug the tablet in when twrp is up it comes up in device manager as b3 Target_Device=b3

tried using lg support tool but it doesn't detect it obviously since it's not displayed the tablet name correctly.

tried using flash2 to flash the system and boot img but flash2 says it was successful almost instantly without actually doing anything.

So what now? LGUP does not show its connected.

I can access ADB and I access twrp.

I flashed twrp to boot and recovery(stupid me)

Updated Instructions:

Prerequisites:

1. Download the following:

The .dz File

Download LGUP following the instructions in the thread for installation.

Download LG Bridge for Windows PC for necessary device drivers or use the quick download

Download this .dll file https://www.androidfilehost.com/?fid=24588232905722773 - Rename LGUP_c.dll to LGUP_common.dll

2. After installing LGUP, go to C:\Program Files (x86)\LG Electronics\LGUP\model as an administrator and

add a new folder 'common' ("\common") and put the .dll file there

3. Backup the device with LG Backup.

4. Unlock the device bootloader if you haven't done so already.

reboot bootloader
fastboot oem unlock
fastboot reboot

5. Check if the bootloader is unlocked by entering:

fastboot getvar unlocked

After finishing the prerequisites above, it's time to ROOT!

1. Plug your tablet to your host computer. If the battery is lower than 50%, please wait because the process may take up to 15 minutes.

2. Set the USB to 'File Transfer Mode.'

3. Open LGUP and select the LG G Pad X 8.0

NOTE: If it doesn't appear, you may not be in 'File Transfer Mode,' missing device drivers, or have a faulty USB port or cable.​

4. Choose "Upgrade" and locate the downloaded .dz file. Press start when you're ready.

5. Wait about 15 minutes and it will finish. The process will hang for a bit at 99% or 100%, this is normal

6. Update SuperSU binary if necessary. (Optional)

You can also revert to stock or unroot when desired

1. Use LGUP and flash the stock .dz

Special thanks to [MENTION=4965298]tungkick[/MENTION] for making the rooted .dz file. [MENTION=303482]mingkee[/MENTION], copy these newer instructions into your post, if desired, by quoting it and removing the quote tags.

After following the instructions above, (not the bootloader unlock part, which I know wipes data), will my data still be there or do I have to set the tablet up from scratch? Can I restore user data from LG backup?

Also, if I want to install twrp, it looks like that only works if you wipe the data partition to get rid of encryption too, right? So basically, even though the bootloader is already unlocked on my tablet, to get root and twrp is going to require a setup from scratch?

And if I'm not using adoptable storage now, it's not possible if I want to use TWRP right?
[LG G Pad X 8.0 Guides, News, & Discussion] mingkee:
Yours will be restored 99.9% with LG Backup EXCEPT Chrome.

All opened tabs and pages will be reset.

Note: MAKE SURE YOU MOVE/COPY .lbf file in /lgbackup to memory card, or set LG Backup to backup to external memory.

Give it 5-15 minutes, depends on your memory size, to let the tab to read the memory in order to restore.

I don't suppose any of you who have access to your bootloaders and oem unlocked, have tried 'fastboot flashing unlock' at all? I got curious where the info is stored that seems to lock me out of my bootloader and started digging into the t-mo 10c's aboot.elf (bootloader); it has the software to do flashing as well as supports both 'oem unlock' and 'flashing unlock' commands (as well as lock).

Unlock bootloader:

fastboot oem unlock
[LG G Pad X 8.0 Guides, News, & Discussion] joeblowma:
Yes, I know t-mo bootloader can be unlocked; but after unlocking your bootloader did you try unlocking flashing? The bootloader code for t-mo v521 seems to support the command:

fastboot flashing unlock

as well as

fastboot oem unlock

in short: they stripped oem unlock code from the binary for rogers/fido v522, it made me curious if the t-mo versions could also do direct flashing from fastboot/bootloader via this additional unlock which seems intact in the bootloader - which I'd guess would also be able to make rooting faster/more future proof/simpler now that there is a (mostly) working recovery.

[LG G Pad X 8.0 Guides, News, & Discussion] joesee:
Usually when that happens, you have either the incorrect USB drivers installed for fastboot (ADB Device). Try uninstalling and then reinstalling the same drivers with admin privs in Windows and give it another shot.

Sometimes, I'll even go into Device Mangler and update the driver without rebooting and that solves the problem too.

Will this method work on the updated Software version V52110e?
[LG G Pad X 8.0 Guides, News, & Discussion] SiNJiN76:
Not sure why, but every time I plug the Pad into the computer...it reboots on it's own and goes into Download Mode.
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
I would assume that, if someone where able to retrieve the update for the V52110E version, we could simply modify the files to contain SuperSU like we did with this version ("we" being someone more educated in this subject than you or I). Of course, LG may have already patched this exploit, meaning we could no longer use it and would have to wait for a new way to root. Obtaining the OTA would probably require some program like WireShark - something I personally have no idea how to use.

This rooting method alone, without updating it to the V52110E version, will most likely not work - it would require downgrading, and I doubt that any LG program would like that. But hey, you never know!

LG devices don't have download mode; they only have fastboot, recovery, and, of course, normal Android. Are you sure you aren't in fastboot?
[LG G Pad X 8.0 Guides, News, & Discussion] SiNJiN76:
Awesome. Thanks for replying. The tablet reboots into a screen that says Firmware Update. I uninstalled everything for the prerequisite of rooting... even the drivers... and as soon as I plug the tablet to my PC... it reboots straight into The black screen Firmware Update... Ana I've got to hold the power button for what seems like a whole minute to get it to reboot.

Now that I know I shouldn't try to root... But I would like to be able to easily transfer files to the PC.
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Maybe try a different USB port on your PC and/or a different USB cable. Or, you could transfer files to a USB drive on the tablet, then transfer those files to your PC.

By the way, I was doing an update through LG Bridge from V52110B to V52110E (probably a huge mistake on my part), and I found a file called "LGBridgeDebugMsg.txt" in the TEMP folder of my Windows account's AppData. I was looking through it, and it seems that LG has an anti-downgrade "protection feature" with QFuses, which might mean that downgrading will be very, very difficult. :(

But, I did find the name of the V52110E KDZ: V52110e_00_1004.kdz. While downloading the update through LG Bridge, it downloads the file to

C:\Users\name_of_user\AppData\Local\LG Electronics\LG Bridge\SWUpgrade\Image\name_of_update.kdz

I don't know if this information could be useful or not. Unfortunately, I could not find the URL in which it downloads the KDZ in the first place. If anyone wants the LGBridgeDebugMsg.txt (with SerialNumber and Phone number removed, of course), I've uploaded it as an attachment. I've also uploaded the KDZ part I found interesting, although it's the same as the bit found in LGBridgeDebugMsg. I just removed all the "nonimportant" stuff. If I left any valuable information in there, such as my serial number (although I'm pretty sure that's redacted), please don't do anything malicious with it, and do tell me!

The attachment is named "LGBridge.zip". I had to zip it up because it was too large for XDA. The files are named "LGBridgeDebugMsg.txt" and "KDZ.txt". I'm sure you can figure out why they're named that.

EDIT: I managed to find the V52110E KDZ online (wasn't really that hard, to be honest), and I've decompressed it with a suite of Python programs named kdztools. I'll see if I can upload the decompressed KDZ and the extracted DZ in a zip, at the size of about 4GB, later; it will take several hours to upload an I currently do not have the time. I can't upload to XDA because of size restrictions :/

I hope someone finds use in all of this!

EDIT2: Sorry, but it looks like I just don't have the time to upload the files. If anyone wants to extract them themselves, you can find the KDZs here.

Happened to me, too; I tried using a cable that worked with all my other devices for ADB and fastboot, of course only the LG one worked :P
