Lock Screen Missing Features - G3 Q&A, Help & Troubleshooting

Hello everyone. I have recently discovered that my LG G3 (32 GB model, running Android 5.0) has some missing features in the lock screen. The "None" feature which disables the lock screen completely was missing but for some reason it showed up when I deleted the Guest in my phone. I also know from various photos on the internet that the LG G3 has a function where you can unlock your phone by letting it recognise your face. This "Face Recognition" feature is also missing and I haven't managed to find a way to get it back. Can someone help me?

Face Recognition is removed from most of phones nowadays,because easily somebody else can unlock your phone with his face..
And as I've seen some companies are developing this feature.
For the "none" i think in 5.0 LG removed it.(I'm not really sure about that)well you can use "swipe" for now.
Also why don't you upgrade to 6.0?It has the "None" for the lock screen and also it has really great performance!

Yeah well I've tried to upgrade it to Marshmallow but I don't know how. I tried LG pc suite but that didn't work. Do you know how to do it?

Connect your phone to your PC
Download Lg drivers(Not Verizon one's!)
Download Lguptool, unzip it,open the folder and inside of it where all the lguptool files are located move the kdz file that you downloaded.

Thanks! I really appreciate you helping me! But do I need to root my phone in order to do that?

No there is no need to Root your device.Only follow the guide that i made.

Okay! Now that I got back my computer I can do it. I just have one more question. My phone will be updated by installing custom roms? Will that wipe off my phone's guarantee? Because it lasts for two more years and I don't want to lose it now.

[ROOT] Root your G2 [ATT|VZW|TMO|KT|RGS|BELL|TELUS|OPEN] [Yay!]

Howdy everyone!
Here's another neat root!
What is this?
This is a very simply and easy to use root package for the LG G2.
For now I'm calling it IORoot, despite the fact that it's not really all that deserving of a name.​
Which phones does this support?
Currently the following phones are supported by this root package:
AT&T G2 (D800) - D80010d
Verizon G2 (VS980) - VS98010B (Shipping ROM)
Verizon G2 (VS980) - VS98011A (OTA)
T-Mobile G2 (Shipping ROM)
KT F320k (Shipping ROM)
Rogers D803 (Shipping ROM)
Bell D803 (Shipping ROM)
Telus D803 (Shipping ROM)
OPEN D802 (Shipping ROM)
How do I use this?
Here's a video!
Or, in List Form:
Ensure you have the proper USB drivers installed, and your phone is in the proper mode (For Verizon, use Ethernet mode on the PC settings menu)
Enable Developer Mode on your phone and enable USB Debugging
Extract this zip file somewhere on your PC
Run root.bat
The phone will ask you to disconnect USB, disable USB debugging, then re-enable it and plug the phone back in, do so when prompted
You will then be asked if you would like to have a superuser package installed, which you can accept or decline
Why is it asking if I want to 'trip rootchecker'?
LG's phones come with some software loaded that detects the presence of root on a phone, and invalidates your warranty.
Rooting the phone, by nature, voids your warranty. You can put your phone in a special mode where ADB shell has root permissions, however your phone is not technically 'rooted' by app standards.
You will not be able to use 'root required' apps on your phone if you do not let the root script install Superuser.​
Okay, where do I get this?
See @autoprime's post here: http://forum.xda-developers.com/showpost.php?p=48709232&postcount=869
-- OLD VERSION --
Code:
[url]http://downloads.codefi.re/thecubed/lg_g2/root/ioroot10.zip[/url]
I'll be keeping this link up to date, and changing the version number as new releases come out.
Please do not mirror this link, as it makes my life easier to keep everything under one roof. Thanks!​
News:
NEW UPDATE: Now supports F320k on KT
NEW NEW UPDATE: Supports the VZW OTA, haven't confirmed yet, but this should do the trick.
NEW NEW NEW UPDATE: Thanks to DeamonFish in IRC, we now have a lovely howto video for this root!
NEW NEW NEW NEW UPDATE: Rogers AND Bell AND Telus AND D802 now supported!
Okay guys, so, @autoprime is taking over from here -- see his post http://forum.xda-developers.com/showpost.php?p=48709232&postcount=869 and be sure to thank him!​
Help! I cant even! I accidentally a phone!
Calm down, don't panic. Join us in #lg-g2 on Freenode.

I'm IOMonster on IRC, I still don't know why I have two nicknames. Personality disorder I suppose
PLEASE don't PM me on XDA asking for help. My inbox has exploded, and can no longer handle it. I will not be able to help you over PM of any sort (IRC or XDA, or even email).​
Alright guys, let me know if you run into any issues!
thecubed said:
Howdy everyone!
Here's another neat root!
This is confirmed to work for the ATT and Verizon variants, I'll add support for T-Mobile as soon as I get someone in #lg-g2 in Freenode who owns one.
Simple:
Ensure you have ADB drivers installed and USB Debugging enabled
Extract this .zip file somewhere
Run the root.bat file, and read the instructions
During the installation, you'll have to disable USB Debugging and re-enable it, then the app will ask you if you care about rootcheckerd (rctd).
If you don't want your phone to show "rooted" in download mode, or in settings, hit CTRL-C when prompted and you'll just have a root shell through ADB.
Personally, this is enough for me, but if you want full root, press continue and it'll install superuser and a superuser binary for you.
PLEASE do not mirror this! It makes my life easy if I can just edit the file on my server if need be instead of contacting all the mirrors.

First!!! Thanks IO and all the devs responsible :highfive:
Can you explain the difference between root shell (leaving it to say unrooted) and "full" root? Will this affect once we get a way to unlock the bootloader or get a recovery for roms? And is there a way to unroot? Thanks for this!!

Root shell allows you to have root only through ADB. Apps on the phone will not be able to use the root functions of the device if you don't let my script install superuser.

The other thread contained a link to a root that could possibly compromise your phone's security (and your desktop too, since there's all sorts of other stuff in those exe files).
If someone pops into the #lg-g2 chan with a TMO phone I'll gladly support TMO as well!
If you did happen to use the old root, I'd recommend restoring your phone back to stock with the TOT / KDZ files before applying this root.

You need to have the android sdk installed on your computer. I find it easier to use a distro of linux but windows is fine too. Find android sdk install and make sure adb is in the /platform-tools folder. Then run this adb devices cmd with your phone attached via usb and if it works you should have an rsa security pop up on your phone you have to allow. Then your phone is connected via adb.

how does one "pop into the #lg-g2 chan" ? i have a tmo g2 and i'm no dev or hacker but i'm clever and have been rooting and customizing since 4.0.
all i really want at this point is the ability to remove the bloatware and then possibly unroot

You will need to go back to stock, and then reroot with this rooter.

[Q] TWRP bricked My LG optimus G Pro...help

I can't access files from usb or micro sd. Can't connect to my lap top. How am I supposed to put a ROM on my LG? The TWRP is loaded, but I have no rom on the internal SD, so there is nothing to recover. TWRP is like a virus, it wiped out my phone. I can access the terminal mode on the phone, but how do I use that to load a rom? All I can find is Greek to me, stand on one leg, look west, hack a key, toss some salt over your shoulder, blah, blah, blah. There must be a simpler solution. This isn't a recovery project, its a destruction project. I used a custom recovery a few years back with no trouble on my Samsung I897. Please, if u understand how TWRP works, help me out.
Vic
As far as I know, Twrp for optimus g pro can't read the external SD card. Have you download the lg device drivers and install them on your laptop? Sounds like you haven't done so, otherwise your computer should be able to read your device. Once you establish the connection, you be able to transfer the file or flash the oem firmware. Everything you need is on this forum, search the topic on flashing the stock rom, there you will find the device drivers. Understand your frustration, but half of your posting is you *****in' and that doesn't help.

Have you try adb side load? If you have 2.3 or higher version of Twrp, you should have the side load function. Within adb you can push the file into which ever directory in your device. Other than the side load, you may have to flash the either cwm image file with lg flash tool or flash the stock rom and go from there.
ADB Sideload, yes I have it

Although I have the ADB Sideload, I'm not sure how to use it. I can access it on the phone, but isn't the idea to use it from your laptop to move files over to the internal SD. How do I get an ADB on my laptop that will talk to the adb sideload of the phone? I tried using the ADB console of my super one click, but it could not see my phone. Sorry to be such a nub about this, but every problem is a new one to me.

You have to flash the base-band if you don't get signal KDZ''ing other phones KDZ, try the e980 Central America or the Mexico Telcel 980 one preferable the telcel since that's what he states will work. Also if a site isn't in English use Google translate or use Google Chrome browser it will translate web pages for you.

ive rooted the lg g4 h815(android 6.0-V20c-SEA) before via iroot pc but after factory reset its returned to be unrooted.
when i try to root again its keep failing because of debugging issue (the software keep telling me its not in debugging altough it is)
i think the problem is when i do usb debugging - connecting to pc the option is checked in the check box but it turns gray.whats the problem is? how can i fix it ?
thank you in advance
If you mean the USB debugging option is checked but gray when your phone is plugged in, that is normal, you cannot change that option when you're plugged in via usb.
I'm not familiar with iroot personally, I could take a look if you need though, but maybe revoke usb debugging authorizations through dev options then accept the pc's key fingerprint once again to "kickstart" iroot.
If you've rooted before through iroot on the same software version you're on now, it should work again without too much effort. Also maybe try switching to MTP (Media Sync) or PTP (Camera sync), or between the both until something happens.
That's all I can think of ATM, I'll probably go check out iroot right now, and think a little more and come back, but I wanted to give you a quick enough response. I wish you the best of luck though!
Edit: Forgot to mention that sometimes SuperSU may get uninstalled from factory reset, if the the G4 Factory Reset protocol deletes the system partition, and then reinstalls it, then this would explain why/if you lost root, I do not know if that's the protocol though. If iroot roots and injects SuperSU as the root manager, try reinstalling it possibly.. unless you are 100% positive you are somehow completely unrooted. (Use a root checker to check if you still got it)
I recommend wiping Data, Cache and Dalvik from TWRP next time, if that's not what you did this time. :good:

thank you for the quick response...
I tried the revoking and debugging again - but nothing.
i will try the mtp ptp thing (when i get home after work)
and will love to hear from you if you have another solution but thank you so much

No problem at all, I really do hope to fix this for you. Are you on the same software version as you were when you first rooted?/Which version is that?
Another thing I thought of, is your computer. Is it the same one that you used the first time? Do you have full admin access on it? Do you have all the LG drivers on it?
Do you have ADB/Fastboot fully installed on it? Obviously these are the first things you probably think about when you think about root, but I'm just making sure nothing is slipping by, you know?
Depending on what software version you're on, maybe we should try another root method if nothing works.
The last thing I'd say is to backup all your data/internal and flash the firmware you want to root on, but I really don't think we need to go that far.
P.S. I own a VS986 (VZW version of the G4) so I can only go to certain extents to reproduce/"debug" the problem you are having. Keep me updated!

Sorry for forgetting the whole reason you're in this problem is because of a factory reset lol, of course you have your data backed up. And trust me, I understand about the brick, I really messed up my G3 2 years back. Thanks also for the device pictures, could you post a shot of "About Phone=>>Software Info". That would be great!
Funny thing I just did that same phone rotation thing very recently XD
Lol love rotation, here

Well, it seems that the factory reset must also have deleted the system partition, then reinstalled it with the most updated version.. which is not good for the current situation.
Notice Security Patch Level is "2016-01-01" and you're running Android M 6.0, means that the software you're on is very recent, if not the most recent. I did some looking around just now, but I couldn't turn up anything that achieved successful root on "V20c-SEA-XX", which is what you would need.
Technically you could try the stock firmware KDZ for your device, which should be 5.1.1, then flash it with like LGUP, but I seriously don't recommend that unless you find a thread that confirms a working downgrade from V20c-SEA, because if the qfuse does not match between firmware versions, you could easily end up with a hardbrick.
Here is the link to your stock firmware, in case you find that it is safe to downgrade from 20c-SEA to 10b-SEA:
http://storagecow.eu/index.php?dir=Xda/LG+G4/H815/
You could try this: http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS
I'm not sure it will work, but I can't imagine it'd harm you, since it's LG official.
You could also try to fill the checkbox "OEM Unlock", and then try to unlock the bootloader via fastboot. I am not sure if this could possibly cause harm if it does not work properly, so try this at your own risk.: http://oneplus.wonderhowto.com/how-...all-custom-recovery-root-oneplus-one-0156099/ (It's all the same commands even though it says for OnePlus One device. If you happen to unlock the bootloader using fastboot, do not go on to Step 2 on that page)

I apologize for such a long wait time + post! I wish you good luck again! :good:
P.S. You should include your current software version in your OP (Android 6.0 - V20c-SEA) so people more knowledgeable than I may be able to help you even more.

ok
i think i find the problem- the adb is not working
i followed to unlock bootloader of lg, { https://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS }
and when do this step:
"Enter your phone’s unique Device ID. You can view the Device ID by connecting your phone to the PC using a USB cable and entering "adb reboot bootloader" in DOS command window of the folder you created in previous step (for example: C:\tools). Your phone will reboot into the fastboot mode. Enter "fastboot oem device-id" in DOS command window."
it says failed to start daemon - error cannot connect to daemon.....
and i cant trace lg id.
any sugestion?

Alright, so I guess it does have something to do with your adb. First off, check your Firewall, make sure you allow adb through and out your Firewall, also maybe temporarily disable your Antivirus whilst using adb, or allow a connection through it if you can. Try turning off USB Tethering through your G4. Try going to Task Manager and ending the adb process tree, it should then try to restart itself. Don't use a wireless adb connection.. if you were trying that, although I didn't think you were.
In "short" order,
1. I would firstly suggest allowing access through your firewall/antivirus, or really I would disable both for now just in case
2. Then try killing the adb process tree in Task Manager
3. Try the adb commands: "kill-server", "start-server"
4. Install any device driver you would possibly need
5. Reinstall adb and fastboot, maybe just install entire SDK-Tools package if you don't have it already
-- If adb is not recognizing your device, which is why you can't track your id, then you can simply enter "adb devices" and it will list your device whenever your error is fixed.
That's all I can think of ATM, I'll post this now but I'll still be thinking of other options. Let me know what happens. Fingers crossed.
(You are starting the command window in your adb directory right?)

We're working on H815 SEA though.
Edit: Your guide is for EU v20d, she's on v20c on the SEA, do they use the same exact software? Is there a pending update for her?

i stopped the firewall and tried killing the adb process tree in Task Manager
done "kill-server", "start-server"
Install any device driver you would possibly need- i think i installed everything but im not sure though
done - Reinstall adb and fastboot, maybe just install entire SDK-Tools package
when i try adb devices - daemon fail
im frustrated

Trust me, I understand your frustration, I'm going to make a guide for you in the next 6 hours or so.
Try a different computer if you can, I haven't had adb fail but many other tools sometimes work
on different computers for me. I've also heard "Dell PC Suite" should be uninstalled as it could cause adb hang ups,
if you have it. @htr5's guide might work for you if you have a software update available, I'm not sure though since it's not specifically for your device.
Regardless, I'm sure you will need to use adb soon, so we have to fix that.
I will try to make that guide asap, I obviously can only do so much, again, since I don't have your device, hopefully it will help though. I highly suggest trying on a fresh/different computer though.
Edit: Try USB 2.0 if you were using a 3.0 port (3.0 ports have the SS along with the usb "logo")
USB 2.0 is on the right:
"H815 SEA Root/General Guide"
@mikmikush
It does seem that you can treat your SEA device very similarly to the EU common version, in ways such as flashing KDZ's and rooting.
I cannot confirm this, but mentions in this thread: http://forum.xda-developers.com/g4/help/safe-root-h815-v10b-sea-variant-t3184152 make it seem like it should be okay.
Aoi_sora9x said:
I'm a SEA variant holder here.
It's fine, you can use the Low Effort Root method. You can also flash the EU open KDZ without any problem.
You lose VoLTE, but to me it doesn't matter so I don't really care.
I'm running the latest 10E ATM, and it's much much better than 10B, so flash away.
Click to expand...

Yes, that post is for v10b, but it should also work for v20d/v20c. (Not the Low Effort Root method) - You will be working with EU software v20d.. while you are with SEA v20c,
so it's up to you if you want to try this, but it's the closest I can come right now. Thank @htr5 because I believe he has all of this in his guide, and I'll probably send you to his guide halfway through.
You may lose some features or brick your device by flashing firmware/software made for other devices. Trust your instinct!
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Install adb setup from here this includes necessary adb drivers, adb itself, and fastboot.
2. Install LG Mobile Driver
3. Download LGUP tool from here (This is for restoring your device to stock if you softbrick via KDZ)
Follow this thread if/when you need to.
4. Here contains a KDZ for EU v20C, which I'm 99.9% sure will match your current software, even though it says for EU.
5. Here contains every partition including the KDZ for 20d by @autoprime, which will be necessary if you decide to root from @htr5's guide (v20d Root Method)
6. Once again, try to unlock the bootloader officially through LG, if you are successful, you can follow @htr5's 20d Root Guide here
7. Be careful and let me know how it goes
@autoprime Mentions that there is "NO anti-rollback qfuse used in this update" (20d) so if you flash the 20d KDZ and it works, I believe you should then be able to downgrade successfully to an earlier firmware version - without worrying about qfuse - and root using a Lollipop (5.0/5.1) method if you can't get anywhere on Marshmallow (6.0). - This I'm not 100% positive about, again, but it is my thinking.
Please thank anyone I mentioned and anyone who's link I provided, they all deserve it!

Lenovo ViBE p1 Root

Hi everyone. I am new and I agree that I am complete noob in this field. I have never did any update to my stock vibe p1 ROM because it runs very smoothly and I never encountered a single issue like other users had. Now I want to just Root it but I don't want any upgrades( in terms of version update). I know that this question may have been answered earlier but all the listed method is so confusing. Can anyone please just put the step by step instruction on how to root my vibe p1 and please share the link of the necessary files in this thread. I am sorry for wasting your time but I need to root it to gain access to my network settings. Thanks in advance. :angel:

Try Kingo Root.
All you need is an laptop or pc, or you could try Kingo Root apk file.
Look on uncle Google for this app.
Good luck.

You could tell this important information in your o.p. so we can skip this step.
Now... write here what your system is, like what is written in: Settings/About phone/Device information/Build number.
What you have to do is to read some articles from here: http://forum.xda-developers.com/vibe-p1/development/qpst-flashing-vibeui-3-1-s272-rom-t3386650
I think, if you dont know what to do, go to someone who knows and can help you.

Thanks for reply. That is the exact thing I meant when i called myself noob. My build is p1a_42_s137_151028_ROW. I did mentioned I got confused though I know this is not a new topic. I think the process (in the link) is for upgrades and what I want is just root because I never got a 100% satisfied user after any upgrades let it be via ota(starting with 30mb patch) or custom Row. My handset works perfectly fine. No lag no heating , no battery draining, etc. I want to root because I want to tweak network settings which is not possible with non rooted mode as SQL is not accessable. Sorry i was not able to provide whole info but I truly don't use blogs or social sites so I lack the idea.

Tell me one thing!
When you tried to root your phone with kingo root tool, did you activated USB Debugging option from developer section ?
If not, activate this option from developer option and try again.
To activate this option you must go to : Settings/About phone/Device information/Build number and press fast many times on it till developer tab is activated.
Go to Settings/Developer options and activate the option from there.
Write here what is going on.

Yes sir I did that via USB connect option. Did anyone had success with kingoroot? But they did not mention vibe p1 in their support list. Thanks for quick reply.

you are right the root for this device is not avialable by kingoroot.they r actually working on it , may be in future we will get it.
There is a bootloader lock on the phone. Applications is useless. The bootloader must first be unlocked, or root application must be installed on the rom. The best solution for you is to unlock the bootloader lock and install twrp. Please see the following page:

That entire process is for unlocking the bootloader? Let's say I have done that but how can I get rooted without updating my raw row?

Well I can only say that with my rom 288 the process was If you have already unlocked bootloader is using QFIL and selecting rawprogram_twrp.xml put supersu zip on your sd card boot into twrp recovery and install supersu zip.

It probably works with the qfil file of your same rom. You need to add and flash bootloader files into the same rom(data can be deleted). ROM version is not important for the bootloader file. If the process is successful, you can install twrp and supersu.zip

Cazzo... did you try the search box?
Doesn't matter. If I already lost a minute writing that, I can also advise you...
Flash V20p.kdz with LGUP. Don't forget you need to use the right .dll for the phone to be recognized.
If you use the search box you'll find what you need.

If you're stuck in LG logo boot up, just try to start LGUP (having the right files), connect the phone to a USB2 port and start the process.
Today, after try the RR ROM, I re-install v29a with TWRP but got stuck on the LG logo boot up, I just disconnected the phone from the computer, turned ON LGUP, connected the phone, was detected as it should and re-flash the v20p.kdz again. No problem... try it.
