Are there any linux solutions for rooting this? It seems at this point everything is done through the LG app.
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
Any chance we will get someone to root the Nougut kdz? I saw some say that it made the v521 feel smoother. That would be nice, including root.

---------- Post added at 11:48 PM ---------- Previous post was at 11:47 PM ----------

Did you ever find a solution to rooting on Linux?
[LG G Pad X 8.0 Guides, News, & Discussion] jdub01984:
I put together a Nougat root guide here. The root portion uses the dirtycow method and all of the commands are run in adb, so it should work in linux. The root method should work in marshmallow as well, but is untested. You will need to update the tablet via OTA to nougat (unless you want to test the root method on 6.0 before updating to verify it works), as I am uncertain of how to flash the kdz in linux.
[LG G Pad X 8.0 Guides, News, & Discussion] klm2349:
There needs to be more clear instructions as to flashing back to stock. Another user and I have both basically created soft-bricks by using LGUP and flashing the stock .dz. We can boot into fastboot or twrp. I have reinstalled the two ROMs iPioneer slim and iPioneer stock and neither works to let me boot to system. I have formatted data. Erased and formatted everything I know how. Nothing seems to get me to boot up the device. The LGUP tool doesn't recognize the device in recovery or fastboot mode.

I successfully updated to 7.0 and rooted with dirty cow method.

You can find the method in Development section.

USB OTG fully worked with 7.0
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
I keep seeing more and more people mentioning soft bricking this device when attempting to upgrade with LGUP. Now I'm beginning to worry about trying to update to rooted 7.0 myself.

Did you find a solution to this issue? Several people have asked for help, but from what I can see no ones has responding with help or a solution. And no one has edited their post with an update.

Unfortunately I don't have a recommendation of how to proceed :(
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
Use the uppercut version of LGUP.
[LG G Pad X 8.0 Guides, News, & Discussion] mingkee:
There's a manual root guide for 7.0

https://xdaforums.com/v20/how-to/instruction-to-root-h918-10i-t3536472

It's intended for V20, but most of the commands can be used on V521 except app_process64 must be changed to app_process 32

Dirty cow files must be for ARMv7

Supported TWRP can be found in Development section

Required dll for LGUP

https://www.androidfilehost.com/?fid=385035244224411840

Rename to LGUP_common.dll
[LG G Pad X 8.0 Guides, News, & Discussion] klm2349:
I think my biggest problem was hurriedly clicking refurbish instead of upgrade in LGUP. I finally got it back to stock by popping the back cover off, unplugging the battery cable and then restarting the tablet while plugging the battery back in.
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
Did you use the Uppercut version of LGUP or the original one?
[LG G Pad X 8.0 Guides, News, & Discussion] klm2349:
I used the regular version but it worked after unplugging battery cable.

Still on MM so I can not flash it. I will wait for news about it cause is experimental. I hope no bricks comes with it. :good:
[LG G Pad X 8.0 Guides, News, & Discussion] Stonkers:
Thank God you wrote this. I just started downloading it without knowing you can't flash it over mm
[LG G Pad X 8.0 Guides, News, & Discussion] xtremelora:
LineageOS 13 it should be for MM and 14 should be for Nougat.

If this rom is working fine is easier to port the device tree to get LineageOS 13 which it would work on MM.
[LG G Pad X 8.0 Guides, News, & Discussion] googlephone:
Of course you can flash lineage 14.1 (android 7.1.1) over stock MM (android 6.0.1), just need to do factory reset in TWRP recovery.
[LG G Pad X 8.0 Guides, News, & Discussion] Stonkers:
Lol I'm scared
[LG G Pad X 8.0 Guides, News, & Discussion] Stonkers:
Lol I'm scared

I've had to recover from a few bootloops, doing basic stuff, that on other devices wouldn't be a problem. The system is very delicate in my experience. Once I tried to flash a backup and it just looped. The only way I was able to recover was ADB sidelining ipioneer.. I will flash it if I see one success story.
[LG G Pad X 8.0 Guides, News, & Discussion] Ravoz88:
Why would we not be able to flash it over MM? If we wanted to, couldn't we even wipe everything (cache, system, data), and then flash the zip and gapps?
[LG G Pad X 8.0 Guides, News, & Discussion] xtremelora:
Simple: On certain devices, you might have to update the bootloader and/or radio firmware first to the very latest version available before installing CM/LineageOS. Not doing so might lead to camera, sensors or other features of the device not working properly. We don't know yet if this is the case of LineageOS 14 on 521 on 10c (me). So be my guess...

I don't want to face issues because of that (remember, is experimental).

---------- Post added at 05:16 AM ---------- Previous post was at 05:13 AM ----------

Besides that, if the author hasn't post anything is because he needs to be sure of something before posting a public release on the forum.

Is like my CM13.zip rom (although it was successfully flashable) , I didn't published because is was not complete and may brick or corrupt devices.

---------- Post added at 05:18 AM ---------- Previous post was at 05:16 AM ----------

Soooooo, until that little piece of info is not cleared I can not flash it over MM.
[LG G Pad X 8.0 Guides, News, & Discussion] Munns86:
But

Yes. It runs super well. World faster and smooth than the stock ROM. Only issue I've run into is that it enables the magnetic smart cover feature. It's way too sensitive. With the cover to my case flipped around back keeps making the screen randomly turn off :(
[LG G Pad X 8.0 Guides, News, & Discussion] xtremelora:
Just for the record:

I flash LineageOS over MM and it happens what I first state, soft brick.

May be sensors/hardware failure.

After retry several times I flash back MM and thanks God everything working ok.

So I guess you have to update to N if you want to enjoy this rom.

I hope the developer make public his/her device tree so we can add 13, omni, aosp and other roms. Until now nothing found on github about b3 (just me, shabby, eyeballer)...
[LG G Pad X 8.0 Guides, News, & Discussion] xtremelora:
Yeah!!! That exactly.
[LG G Pad X 8.0 Guides, News, & Discussion] xtremelora:
Well, I would let the original author improve the rom, clearly he knows what he is doing.

When I was compiling cm13 I research for the b3 device tree but never found it, somebody point me to the repositorie of eyeballer and shabby, that was all.

What it is good is the fact that with the device tree already complete (as the rom is working) someone can fork it and build more roms with that, for example, a dev can take that device tree and make little changes in order to obtain LineageOS13, pure AOSP, Omni, etc...

The most difficult step is already done (device tree, vendor files, config files, etc) now the people who has the time can build new roms from that.

Trying to update to LineageOS from MM did soft brick my device. I then decided to follow the dirty cow method to update to Nougat with TWRP.

After N was installed, LineageOS flashed just fine.
[LG G Pad X 8.0 Guides, News, & Discussion] Munns86:
Good to see you got it work! For what it's worth I do think LineageOS is worth the trouble compared to the stock ROM.

Imo lineage is significantly "quicker" in transitions, installing apps, page loading than the stock LG app. Makes me wonder how lineage would be on a V20 with full DAC support (wishful thinking of course due to the drivers)

Help! LGUP Error code

Trying to flash the dz file. At 10 percent I get the message Error: Error Code = 0x2BC, Invalid command response code = ox80000121

This is a t-mobile lg-v521. It was already on Nougat. I thought maybe the error was the dll file. I created a folder named common and put the LGUP_common.dll

in it and moved that folder to the model folder, but it does not show up in there. I'm on an adminstrator account. But when I redownload the file and try to put it in there again, it says the file already exists.

Whats the proper way to do it? The tablet was just over half battery and is on Firmware Update screen do not unplug the usb connection until the process is complete. It shows 1%. I'm afraid its going to die. What do I try ??

---------- Post added at 02:39 PM ---------- Previous post was at 02:23 PM ----------

So I ran LG bridge and am not sure if i did the Software update or the Update error recovery. Anyway, it downloaded a 1.6gb file and installed it and the tablet works fine. But I still want to root it. I thought I could flash the dz file and be done but do I need to flash the dirtycow files?

[LG G Pad X 8.0 Guides, News, & Discussion] hectoralexgarcia:
I know that the tablet needs to be unmodified in order for you to exchange it. When I exchanged mine, the T-Mobile rep at the store did not go far into checking for modified firmware/bootloader... all the rep was concerned with was the IMEI of the tablet, that it wasn't damaged physically, and that the water indicators were not triggered. But that is one of the statements mentioned during the disclosure over the phone once the tech has decided to issue a replacement.

When I reboot the phone, most of widgets were back but some have been missing yet.

Furthermore, in appdrawer there's no app at all.

I can run app from Google Now searchbar and home screen shortcuts, but nothing is in appdrawer.

I uninstalled and re-installed the launcher but nothing solved.

Just played with it a bit more. If you don't need Secure Folder, you can just install that. Google Now Launcher will work correctly after rebooting.
