They have around 4 or 5 different cables provisioned in the software mainly for service/mfg purposes, possibly quick charge, as well as a normal one. A really long cable, one with a pin floating/unattached, or one with very thin wires in it might incidentally meet the resistance thresholds for detection as a custom cable triggering different behaviour. Initially I was hoping one of these custom cables could get me into fastboot before I dug in and found the v522 bootloader was neutered. I've been using other cables to the PC without issue, though they are very short (under 3 feet) and my nexus 7 2012 charger/cable gives me normal charge times compared to the one that comes with the device.

Check out a program called Fiddler (by telerik), makes it fairly easy to snag links and other activity from other programs rather than raw captures like wireshark does.
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Cool, I'll look into it. Of course, it's a bit late now - I've already updated - but if anyone else still hasn't updated, and just so happens to read your specific reply, I'm sure it'll make things easier :)

Do you think any of those extra cables might help us get deeper into the tablet? For example, can the Firmware Update mode somehow allow us to install an unsigned (rooted) OS?
[LG G Pad X 8.0 Guides, News, & Discussion] joeblowma:
Unlocking the bootloader allows you to install an unsigned/broken signature system image - download mode can do pretty much anything it wants to the system flash which is how the pre-rooted kdz gets flashed. I'm sure there is some kind of default/factory mode that needs special qualcomm tools that can deal with the device at an even more raw level, don't know if it needs a special cable or if there is software/images available for it on these snapdragons though.

I'm still wondering if v521 will allow 'fastboot flashing unlock'; IIRC that was how I initially rooted my nexus 7 - flash twrp from fastboot and install chainfire's supersu/root from a zip via twrp (so long ago now that I'm not even sure if it can still work this way post-kitkat). So far as I know though, no one with a t-mo/unlockable gpad 3 has tried it - and in the end its probably easier anyway if someone creates an update pre-rooted that would work with flashify or twrp. I'd do both, I have the time/motivation/skill but my device is crippled by the carrier - so for me its all just theory.
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Ah, well, that certainly makes things easier. But if LG/Qualcomm allows all that, why do they have "anti rollback" protection with QFuses? If they don't, then why does the LG Bridge debug log state as such? Also, would using download mode without the bootloader unlocked permit the device to be rooted without wiping everything from fastboot?

And it's up to us to find it, right? ;)

If we somehow manage to access this special mode, what, exactly, would we be able to do with the device? Is it similar to what Apple devices can do with BootROM access, such as replacing the bootloader? Obviously not installing some other distribution of Linux (like Project iX all those years ago), since we can already do that. :)

I thought "fastboot flashing unlock" was the same as "fastboot oem unlock"? That's what the Nexus factory images page says, anyway. As far as I know, flashing recovery from fastboot and installing SuperSU via recovery still works on modern Android versions - it works on my Nexus 5 with the Marshmallow bootloader, at least. Also, is there a difference between the G Pad X 8.0 and the G Pad 3? Besides the screen size and/or name.
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
Everything is different except for both being tablets from LG.
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Really? They look pretty much the same to me, at least from comparing the V521 (G Pad X) on GSMArena and the V522 (G Pad 3) on LG's website. Heck, even their internal names are almost the same! (V521 and V522)

Though, I notice you may be thinking that I was talking about a different G Pad 3, other than the V522; maybe the G Pad 8.3. Sorry for any confusion I may have caused.
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
I thought you were talking about the G PAD 8.3 because you mentioned different sizes.

The gpad x and gpad III have the same size of 8 inches.
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Yeah, sorry about that. Guess I'll be a bit more specific next time!
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Ah, yes, the chain of trust... the bane of my existence. I suppose it wouldn't even be legal to use these keys, and that would only be if we managed to obtain them.

If only this device was a bit more popular - maybe with T-Mobile practically giving them out for free with some sort of upgrade as of recently, it'll get a little more attention?

Oh, that's a relief. I suppose I'm not surprised, though; I've never had a device from T-Mobile that couldn't have had a downgrade engaged... except maybe the Galaxy S7.

Of course, it's not a relief for those who don't have the T-Mobile version. I hope, even with the comparatively little attention they have, that the locked devices will eventually have an exploit :)

I wonder why they use separate touch screen controllers for the two different devices? Maybe because it's cheaper in one place, but not the other...?

I suppose it's a universal factor for big companies to lock up their devices - from Apple and Samsung to LG and HTC. But there's always a way to break into those devices, isn't there :D

Ah, so I guess it wouldn't be that useful after all - except, of course, to be used for setting the fuses and downgrading locked devices. It's all most likely illegal though :/

Wouldn't it not be possible, though, to flash a recovery directly from fastboot - not because fastboot would deny it, but simply because the device has a stripped-down version of fastboot (and recovery)?

I would try out the "get var" commands on my HTC Sapphire; I would try it on my Nexus, but I don't particularly want to erase all my data and have to restore a TWRP backup :)

But, would a device as old as Android itself actually support such a command? Hmm... If only Samsung devices had fastboot...
[LG G Pad X 8.0 Guides, News, & Discussion] joeblowma:
As far as I know there was a gap of a few weeks/months between release to t-mobile and release here, making it possible there are 2 different chips (due to late substitution in manufacture, plausibly for a cheaper part) in the wild on t-mobile devices and only 1 on rogers. Maybe even its to keep some pre-production demo units functioning. Part substitutions happen all the time, usually due to availability or cost.

"get var" is non-destructive and has been around as long as I've had an android. Others tried flashing with v521 fastboot early on and said it didn't work, but whether its because it needs an additional unlock, or it's fastboot is disabled in some way with regards to flashing I can't say... what I can say is looking at both 521 and 522 bootloaders mine has the text/code stripped to do oem lock/unlock (so I can't do it even if I manage to get fastboot to stop automatically booting) as well I see nothing about flashing in 522 though I see it in 521. Thus, curiosity and why I'm still asking about it :silly:
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
The complexity of mass-production. Always making things harder for us end-users! :P

Well, I was going to try comparing the OEM locked bootloader and an OEM unlocked bootloader variables, thus wiping my data because of the lock/reunlock. Reunlock is a word, I swear!

But if I only need to check the unlocked variables, well, that makes the operation a whole lot easier.

Wouldn't we be able to do something like this to figure out which commands are available, and if we manage to get the ABOOT partition of the V522, to compare the commands? Could we just extract the ABOOT from the DZ, or is the BIN unusable somehow?
[LG G Pad X 8.0 Guides, News, & Discussion] joeblowma:
You can extract the dz from the kdz, and the various partition images from that including aboot and the system image - I used "LGFirmwareExtract-1.2.5.0" and it did the job well. Looking at that list the only command I'm seeing that I didn't mention before (oem unlock, flashing unlock) is 'frp-unlock' on v521. On V522 the only occurence of 'oem unlock' is in the text 'oem unlock is not allowed', 'flashing unlock' does not occur but 'frp-unlock' does.

Further searching between the two also reveals that the 522 only supports the red exclamation/tamper screen, while 521 supports all 3; both seem to have something in them for secure boot disable and a development mode, but the 522 doesn't have any normal user method to do the bootloader unlock. I know that in the past LG has issued keys to unlock single devices for developers, but as I can't get it to go into fastboot I doubt they will do that for this device.
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Well, from what I've read, "frp-unlock" seems pretty useless - all it does is removes some security feature that prevents someone who steals the tablet the ability to use their Google account.

Maybe if we ask politely...?

To bypass the bootloader lock, would it be possible to:

1. Obtain temporary root using something similar to Kingoroot

2. Flash a new bootloader with Flashfire/Flashify

3. Reboot to this new bootloader, unlock the device, etcetera?

Of course, there's probably keys protecting the bootloader, and we still haven't figured out a way to root without flashing an entirely new firmware... So, would it be possible to bypass the (hypothetical) keys? Would it be possible to root from userland?
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
What is the current status on rooting the v521? I should have one shipped to me this next week. Reading through all of the post there was some mention of an update to "V52110E" and it sounded like the current root method would be broke with that update? Due to rollback protection? So if my tablet ships with updated software i'm out of luck? Has flashing the rooted .dz after updating been confirmed to not work? Will it brick my device?
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Rollback protection isn't enabled by T-Mobile, so you can still downgrade to V52110C with the stock DZ and root from there, I believe. I'm not sure if it would brick your device, however, so it would most likely be a good idea to wait for some sort of confirmation. It's unlikely that your tablet will ship with the updated firmware; the one I got about a week ago came with V52110B, which is the first software version; at most, yours will probably come with V52110C.
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
The one I received last week came with 10e and was manufactured in Nov 2016.
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
Then chances are the one I get will be updated too.

Googlephone, you were the first person to comment in this thread about rooting your device. I take it your newest one isn't rooted? Or is it? Can you downgrade to the older, rooted firmware safely?

Does anyone know if tungkick or anyone else is working on a rooted 10e firmware? I see the stock 10e firmware has been captured.
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Oh, darn. Now I feel even worse that I updated to V52110E. :/

I sure hope someone roots this new firmware soon, or at least confirms it's safe to downgrade.
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
The 10e version can't be rooted until tungkick updates the root method of 10c to 10e.

But the good thing about t-mobile is that rollback protection is not enabled. As a result, you can use the 10C root method, which is basically by flashing a prerooted 10c image to the tablet, to root tablet with 10e. So you can't have rooted 10e but you can root the 10e with prerooted 10c.

---------- Post added at 08:58 PM ---------- Previous post was at 08:56 PM ----------

Safe to downgrade from 10e to prerooted 10c. Confirmed.
[LG G Pad X 8.0 Guides, News, & Discussion] KittenSauce:
Oh, swell. Now I can go update all my posts saying that V52110C can't be rooted :P
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
Awesome. Googlephone, thanks for confirming that downgrading to the previous rooted 10c, from 10e is safe. I appreciate it!
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
After you root it, google and download "fota kill apk", and put it in system/apps to avoid the annoying update notification popup.
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
Does updating to 10e, after flashing the pre-rooted firmware, overwrite root? And I assume TWRP too?

---------- Post added at 10:23 PM ---------- Previous post was at 10:10 PM ----------

I'll check into it. Thanks again, I really do appreciate it.
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
Don't install the update on the rooted 10c, or it will soft brick the tablet.
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
This device and root method is quite different than my phone's. Is it alright to completely "unroot" using SuperSU app, then reboot into TWRP recover to then flash phh's SuperUser instead?

Once the rooted firmware is installed, root it's self isn't dependent correct?
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
I'm going through the root method but I am having a problem. During fastboot screen I am getting "waiting for device". Windows does not recognize my "android device" in device manager. I've installed LG Drivers and android drivers when I installed ADB and Fastboot. Anyone have any ideas?

EDIT: I was able to work it out by following directions here (stupid windows) -- https://trevorsullivan.net/2012/07/03/forcibly-installing-the-android-usb-driver-in-windows-7/

Where to look/delete if update already downloaded ? I'll use "fota kill apk" to get rid of update notif. after that.

/cache
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
If anyone wanted to use a different super-user manager, full unroot is possible using the SuperSU app. The app hung for me, but after a reboot and a second try it succeeded. The device will function fine without, and is not dependent on root.

Obviously make sure TWRP is installed first and you make a nandroid backup.

With TWRP you can then flash root again. And then use another SU manager if you were inclined to do so.

[LG G Pad X 8.0 Guides, News, & Discussion] xtremelora:
It works hum...

I told you, just try it...

It was worth the risk, right?
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
First you need to make sure you have an unlocked bootloader. As of now, the only version that is capable of this is the T-Mobile version "v521".

Instructions for unlocking the v521 bootloader can be found here -->http://xdaforums.com/lg-g-pad-83/help/t-mobile-lg-g-pad-x-8-0-v521wg-info-t3400620

Second, you have to "Root" your device. Instructions can be found -->http://xdaforums.com/lg-g-pad-83/general/root-guide-lg-v521-t-mobile-version-t3443747

Once you have an unlocked bootloader, and have installed the modified firmware containing root, then you can go about installing TWRP.

You will need to be Rooted to install TWRP, because the method to install it is with an APP you can download and install from the playstore. I used the app "Flashify (for root users)" and it requires you to fist be rooted to use. There are other's that can do the same thing, but that is the one I used.

Instructions for installing TWRP on your device can be found here -->http://xdaforums.com/android/development/team-win-recovery-project-lg-g-pad-x-8-t3443944

---------- Post added at 09:05 AM ---------- Previous post was at 08:55 AM ----------

I think it was worth it, it allowed me to see just what I could do with this new device, by going through the process. Had I not attempted it I wouldn't have figured out that TWRP needed my micro SD card or OTG connected USB formatted in ext4 format to write a backup to. That one had me stalled far too long haha.

And of course I can now use the root method of my choice.

By the way, THANKS so much for your input and help the last couple of days. I really do appreciate it. It's pretty quiet around here. Thanks!

Sorry I did not read the whole thread and jus did a quick search about this issue I just got this tablet yesterday and I rooted right away according to first post, no problem what so ever.

but my main concern is about the android security patch level since by using the .dz file the tablet is at android security patch level 2016-07-01 with is way behind the major 2 last one from November https://source.android.com/security/bulletin/2016-11-01.html

So right now I am kind of worry about the vulnerability of the tablet to some nasty attack
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
Turn off the tablet and put it in a fridge to avoid someone hacking your tablet via wireless waves.

With this type of reply you just turned off people who enjoy XDA forums and their participation please do not add anything to it since I am not interested about your feeling
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
What? I gave you a serious and the only viable type of method to avoid attacks to your device. Take my advice or just forget about worrying about someone attacking your device.

No matter how latest security patch your device has, your device is 100% vulnerable to attacks and you still should be worried about attacks. It's a sad fact you need to face. You or everyone can't do anything to fix this problem or always get the latest security patch unless you stop using this tablet or just buy a pixel/nexus tablet or ipads.

I forgot to do the fotakill apk tip, and I have now received the system update notification. I placed the apk in system/app, deleted the update zip from cache, and even cleared Google play services cache, yet the notification persist.

How can I go about clearing this notification? The apk was from a post many years old, so I don't even know if the apk I have is still relevant? Where is a good place to download the fotakill apk cleanly?

Any advice would be appreciated. Not being able to clear the notification is pretty annoying.

[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
Hold that notification and then go to the properties of google play services, unchecked the box of notification, and check it back.
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
Blocking all notifications from Google Play Services removed the notification. But as soon as I unblocked them, it appeared again.

After that I decided to try clearing all application data from Google Play Services. Data and Cache.

Doing everything suggested thus far, and then clearing all of the app data appears to have stopped the update notification. It hasn't appeared again. I guess I will have to wait and see if it comes back.

It took several days, after installing the older firmware for it to appear.

Thanks all.

Another that worked tor me was deleting the update, disable/freeze these app mentioned above, then hit the Restart and Install button at the botton of the update popup, the popup it start conting down from 10 to 0 to restart but it doesn,t restart the tablet (I guess is because the apps are frozen or disable) and then the status bar notificacion just disapear.
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
The notification ended up coming back tonight. It downloaded the update.zip again too.

So I took your advice. With those apps frozen, I deleted the update zip from /cache, turned on airplane mode and pushed update. It counted down just as you said. And at zero it did nothing. And the notification disappeared.

Hopefully it is gone for good now! Fingers crossed! Thanks a lot !

I think it is gonna work since I can reflash the bin file with LGUP

Update 2

Well it is a little better now it goes directly to TWRP but cannot boot to system and internal storage in TWRP is still 0 MB!

for the heck of it I changed the data to ext 3 and back to ext 4 no more error in TWRP got also access to ADB but sill not booting to system even after factory reset wipe

Update4

Even after wiping everything and reinstalling the mod dz no joy so wiped again and downloaded the original dz the installer crashed at 85% but the tablet booted as new except boot loader still unlocked, so I guess the next step would be to start again from the page 1

but my question why I was getting this error in TWRP "data showed size 0"??
