[Discontinued] - G2 Q&A, Help & Troubleshooting

Download and Install LG United Mobile Driver
Download and Install LG Mobile Support Tool​
Boot your phone into download mode:
Put your G2 into download mode by switching it off, hold the Volume up button and insert the usb cable into the phone; wait for the drivers to finish loading if doing it for the first time.​
Start the LG Mobile Support Tool and click on Options -> Upgrade Recovery

It should now download the firmware (about 2gb) and flash it - this may take some time.
This is needed if you stuck in a bootloop after the flash is done:
Factory reset (this wipe your data and sdcard):
1. Turn the phone off.
2. Press and hold the Power and Volume down button.
3. When the LG logo pops up let go for a second and press the combo again.
4. You'll be prompted to press the Power button 3 times to wipe the device.​

I would hate to have to use this, but wow what a good find. Thanks for contributing.

I used this method last night and it didnt mess with the storage at all. They don't even have a 16gb G2 so who knows. Also are you sure you are not mistaken cause this method doesnt wipe data.

I know it does'nt wipe data, but it reflashes recovery, and in my case something went wrong. But Lg DO sell D802 as a 16 gb model!

Can anyone using this method please post results. Just wondering if there is more success with this method as opposed to the other method. Thanks.

Saved my bacon today!

I don't understand how could this be, you downloaded the specific firmware for your device (using your serial number)...
Can't you just try to flash it again ?

I have reflashed it 5 times The problem was that it asked for some kind of password the first time (not the pin). So I did a factory reset. Now even TWRP says that my storage is 10.66 gb :/

Which password exactly ? when ? in the process of flashing ? the OP mentions no stage in which you need to give password...
What are you going to do now ? your device is not rooted, so you can replace it under warranty, no ?

It did not say what the password was for, just asked for it. It came up after the phone had booted, but before i could see the lockscreen. I will wait a couple of weeks, to check if someone else gets the same problem, or if it is fixable. Otherwise i will hand it in on the warranty since there are not traces of root.

Why should a password appear at that stage ???
If you went through all of the flash process successfully, booted successfully and only then did a factory reset (when you saw that password), I see no reason to blame the factory reset that you did. This is something to do with the flash process. Maybe this is kind of a punishment that LG unleash on those who use this process ? seriously, why on earth would anyone try to flash his LG2, if it wasn't to get rid of root ? I also don't understand how the password went away after you did hard-reset, since the device was "hard-reset" when you did that flash. You said that you re-flashed about 5 times, did that password appear after each of those 5 times ?

Same issue here.
I also got the question after I used the software to enter my encryptionkey. Wich I didnt have.
So I had to hardreset from the recoverymenu (volume down + pwr), then I suddenly had 10.77GB left instead of 26.77GB or something similar.
Annoys me pretty darn much at the time beeing!
I did use my IMEI, not my serialnumber and model. I'll try to use the serial and model this time around, and see if there are any differences at all in doing so.
And yes, it does say 32GB on the back. So we're not mistaken it for a 16GB-model
And it does say that the model is the 32GB when I check the hardware-info on the android itself.
Maybe this has something to do with me using the adbcommand for mounting storage incorrectly?
I thought however it would be reset when I used the LG Mobile Support Tool to hardreset everything though.

Will this work with the AT&T model D800?
Also does this remove all traces of root to the point where you get your warranty back?

what was the solution to this...

Does this work with the TMO versions?

The windows application keeps getting a Windows error and closing shortly after the process begins. Any tips?

I would prob stay away from this if i was anyone else....Because it must be messing people phones up and changing the storage capacity

[Q] OTA update keeps failing to download

My wife got me a brand new A500 off ebay a couple of months ago for a Christmas gift(for me it's only three days old). So far I love it but it will not take the OTA update that it keeps bugging me about. The download starts fine but then stalls out mid download. I looked here http://forum.xda-developers.com/showthread.php?t=1113878 but did not see my current version there. Can anyone point me in the direction of the OTA I need to download and flash with recovery? My build is Acer_a500_1.145.09_com_gen1 I'm running 3.0.1. It looks like it's trying to download 4.010.11.
Further info:
According to the log the file name is Acer_A500_1.145.09_4.010.11_com_gen1_1311243587838_bd1ab95c.zip
I can't find that file anywhere on the net.
The reason I would suspect is because someone replaced the stock recovery? Off eBay you say, was it brand new and never used? It sounds like it was used or someone tampered with it?
If that's not the case, then you can just install the update manually. Download the update you want and put it on your external SDCard and then enter recovery (using power and volume). The recovery will install the update for you.

It said it was brand new. My wife would not buy something like this used. The weird thing is it knows it has an update and it starts to download and get's up to half way downloaded and then it just stops. It shows that it still is pulling data but the downloaded file size doesn't increase anymore after it stalls.
Ive been looking into rooting it and since I'm on 3.0.1 it appears Gingerbreak is all I need. The next question is what rom should I get and how do I go about installing it? I've never rooted droid before and most instructions on XDA are written for the experienced level and not the new guy. I'd like to stay fairly stock but rooted.

There are reports of others having the same issue. They say that a soft reset often fixes it.
You can use my tool to flash in 3.2.1 which is rooted. http://forum.xda-developers.com/showthread.php?t=1307539&page=14

Just to make sure I'm getting it right: I go here http://forum.xda-developers.com/showthread.php?p=20680452 download that to my PC and follow the instructions contained within and I end up with a stock rooted 3.2.1? I don't need to download anything else right? A soft reset for this tab is pusing the little red button on the end by the USB port?
Sent from my A500 using Tapatalk
Yes, if you want to flash 3.2.1 stock with root read the instructions in the download. The download has everything in it.
The soft reset everyone talks about is using the paperclip in that little hole next to the USB port.

[Q] Hard bricked (no boot, no download mode)

I've been digging around online and can't find anything that helps me in my case.
Here's my stupidity: I flashed a kernel that was not intended for my phone (meant for Note 2). Reboot and dead screen. Can't get into download mode, recovery, nothing. Removed battery. Didn't help. Plugged into computer. Doesn't pick up anything connected. Odin doesn't see it. Tried RIFF. Can't get it to install the drivers it's supposed to. I saw something about jig dongles that can force it into download mode but I don't know about that.
What really stinks is I had just compiled SheepShaver for android and it took a few hours of work and I really don't want to do that all over again. Also pictures of my father who's just passed away are on there.
Am I screwed? Is there any way at all to get the proper kernel flashed back on this thing without a wipe? If not is there any way I can fix this phone? I have a semi-recent backup (about a month old) on my SD card. I have both Titanium Backup and a full nandroid backup on the SD.
Someone please come to my rescue. I've logged countless hours on this phone and I love it. All this because I couldn't get SELinux to go permissive...
You already know the answer. If you flashed a kernel not for your device and with the symptoms you have, your hard bricked. Jtag is the answer.

I don't have the equipment to jtag it myself. Also just to be perfectly clear; An incorrect kernel cannot be fixed with a download mode jig correct?

I think you will need the actual riffbox device. I've long since given up on trying to interface over USB. Riffbox talks directly to the memory chip. Need to be comfortable with soldering. But I do happen to have a link to the latest release of their software. http://www.unlockforum.com/showthread.php/riff-jtag-manager-v1-72-more-new-models-32724.html?
Thats the forum they use. The official site is riffbox.org
Sorry I don't know much else to tell you. If it won't boot it won't listen for a connection on USB. Some devices have a failsafe that activates a sort of programming mode over USB but the Galaxy S4 isn't one of those devices afaik.

VS980 TWRP bootloop after botched lollipop OTA while rooted like a dummy

So yeah. As the title says I had a rooted VS980 on 4.4.2 with some bloat removed and I accidently hit the wrong button when prompted for the upgrade, I was in a hurry. yes, I'm a moron, and yes, I know this is probably wasting someone's valuable time and I thoroughly apologize for my n00bishness
having said that, I have tried to go through various tuts but none of them seem to be working. yes, it's likely that I am simply doing it wrong, but whatever the case I am stuck with my phone in a bootloop always returning to the TWRP recovery. I believe that means it is soft bricked so I'm hoping this can be fixed fairly easily with the right direction and some patience for my ignorance. I can't seem to get it into download mode with turning it off, holding the volume+ button and plugging it in, it just goes to twrp. :'(
my hope is to get a rooted lollipop. if that is not possible then I would be fine with going back to stock or possibly even a custom rom if it's not too awfully complicated. honestly, I'm at a point where I'm beginning to accept that I probably shouldn't be screwing around with it too much and will likely bite the bullet and just keep my phone stock since there are really only a few minor irritants that make me want to root it.
any help is very much appreciated.

actually, it doesn't look to be the same problem. i dont have download mode, but i do have recovery. it boots to twrp like a champ. what i think i really need is how to get the flash file VS98011A_01.zip on my phone via ADB Sideload, specifically when i cant get the drivers to work.
i've tried the following drivers:
LG_VZW_United_WHQL_v2.14.1.exe
LG_VZW_United_WHQL_v2.20.0.exe
LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1_3.10.1.0
I may very well be mistaken about what needs to happen, i'm no expert, obviously, but from everything ive read any of those should have worked. i think if i can get the right flash on the phone i should be able to flash it via twrp no?
I"ll help

i just happened to have a brand new data cable, tried again with same result so its not media related unless there is an issue with the plug itself, but it's charging and the Device manager shows the correct name ie VS980, it just has a yellow bang on it and i cant find a driver that changes that.
read some more and found others with the same issue apparently which led me to here: http://forum.xda-developers.com/showthread.php?t=2715408
which is where i found the "download mode restore" file you mentioned(i didnt see it in the thread you provided), but without the ability to get adb usb command to work i dont see how i can use it.
any ideas?

installed
Restore to 100% stock
from the same page.
rebooted. it went into an upgrade screen that errored and then rebooted before i got a chance to write down the error. but when it came back up, it started "android is upgrading".
so it looks like this may have worked. again, will update the success/failure when i know for sure, but thanks for the help yall. i really do appreciate it.

sweet, i'm glad someone else found it useful.
Yep, now another problem though. ..no mobile data. .. working on it.
I'd suggest flashing the files in post 12 (I didn't and am having TONS of problems)
So I really didn't get a fix- still working on it.
I have no download mode, and not way to get the serial port to display in device manager, so the LG Mobile support tool won't see my phone....

Dude first off did you activated oem unlock in developer settings (does this Samsung even have a unlocked bootloader) Since you messed up patching twrp to the recovery you need to reflash stock firmware run the setup wizard after its done go in developer settings and make sure oem unlock is activated or more important is the option even present?
(alright its thier I didn't see the F in your model number)

First of all, my friend did nothing about unlocking oem (you can see from the picture i uploaded, both oem and frp locks are active). He didn't even searched about it . I don't think the bootloader also unlocked. So its pretty messed up right now. I actually tried flashing both android 8 and 9 with different variations, odin always failed. If at least oem was unlocked i think i would do something but, i have no idea waht to do.

Galaxy S8 didn't get android 10 update unfortunately. I'm still thinking that the problem that causes failed flashes comes from probably the roms i have. But i'm downloading from samdb, when it is downloaded i'll try that and it will probably work i assume.

Alright let me know the progress your friend shouldn't tinker without the proper knowledge cause now that expensive phone just a piece of metal once he has twrrp installed he should be protected from this happening again cause then again twrp is a modders best friend

You are completely right sir. Personally, every phone i had for 5 years were all modded and i always do my search before doing anything. What he did was a really big mistake and he could've asked me. At least he took a lesson from happened to him :laugh:
I just took his phone to my home and connected to my pc, i flashed the stock rom without any problem. I decided to root his phone by myself. I don't think he should attempt to do this kind of critical operations alone . Thanks for the help!
I also have another question; he had a backup of his files and apps using Smart Switch. If i root his phone, i know kies and smart switch doesn't work with updating phones. But can it restore the backup on a rooted phone?

Bought a Samsung Tab A SM-T387V, apparently has doordash on it, how can I wipe it and use it as a normal tablet?

EDIT 2022-06-30: FOUND A RELIABLE SOLUTION FOR MY NEW T307U TABLET! May work for other models! https://forum.xda-developers.com/t/...e-it-as-a-normal-tablet.4316969/post-87091297
Original post from 2021-08-09 below:
Following this thread to no avail: https://forum.xda-developers.com/t/doordash-knox-customized-tablet-unable-to-remove.3890522/
Setup requires an internet connection, at which point it sets up MobiControl:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
My friend's an IT so he set up Meraki for me which I can enroll in instead of MobiControl, but a minute later this pops up:
I still have access to the settings but cannot enable USB Debugging.
I flashed a combination file which got me to the "factory binary" where I can unlock OEM and enable USB Debugging, but I don't know where to go from here:
I flashed a stock ROM, but that doesn't get rid of doordash and MobiControl during setup.
Please help!
Which Android version did you flash? Did you finally get rid of MobiControl?

I solved this. Basically, I accidentally bricked the tablet, which I assume is what caused Samsung Knox to fail and thus Mobi Control didn't try installing on a fresh flash of Android 8.1. Fuller story below:
After 3 days straight of trying to reset the tablet, including flashing the combo file, trying anything I can think of, re-flashing the stock rom and seeing if the problem is gone, I finally fixed it.
What ended up happening was, while re-flashing the stock rom on my 4th attempt, I flashed the AP but not one of the other things (I guess CP?) which resulted in the tablet getting bricked.
Long story short, I held both volume buttons and power to boot into a blue download mode (as opposed to a black one via holding power down + volume and selecting download mode, since the volume down + power nor the volume up + power combos weren't working) and flashed the stock rom to it properly.
Upon setup, I was still required to set up wi-fi, but it didn't attempt to install mobicontrol! I've been using the tablet normally since. Who would have known accidentally bricking the tablet was all I needed to do!

After tried 5 versions of Odin, include 2 different v3.13.3, finally got a good news. I can flash T387v firmware Andriod 8.1 and 9. But the bad news is I cannot brick it, no matter flashed only AP or BL. I tried to flash with T387W or T387T firmware, I got PIT error messages.
Which version of firmware were you using?

Thank you. It looks like it's Android 9. Did you update it to Android 10?

It's Android 8.1. If that file I mentioned is 9, then it's not the one I flashed, but was instead on my to-do list of troubleshooting steps. I was going to try flashing Android 9 and 10 but I got it working with 8.1 so I'm keeping it on that. Plus, the newer the android, the more secure Samsung Knox will be, so it will be harder breaking it.
Any idea where you downloaded it from? I cant seem to find a link.

Android 10: https://samfrew.com/download/Galaxy__Tab__A__/1hjk/VZW/T387VVRU3CUI2/T387VVZW3CUI2/
"The fact that it has MobiControl installed suggests it's a company device, and is therefore administered by that company's IT department. It's probably going to be difficult to remove MobiControl unless you talk to that IT department about it."
The above is a quote I found regarding Knox and the MobiControl app. Which tells me that this thread, although likely unintentional, is violating XDA Forum Rule #9:
9. Don't get us into trouble.
Don't post copyrighted materials or do other things which will obviously lead to legal trouble. If you wouldn't do it on your own homepage, you probably shouldn't do it here either. This does not mean that we agree with everything that the software piracy lobby try to impose on us. It simply means that you cannot break any laws here, since we'll end up dealing with the legal hassle caused by you. Please use common sense: respect the forum, its users and those that write great code.

XDA does not wish to be held liable for circumventing device security regardless of intent of the user, which is why I'm closing this thread.
