[G3 Q&A, Help & Troubleshooting] subworx:
The version info is below that KVT49L... string you posted, it says something like V10l_XXX_XX (lowercase L), in this case you have Android 4.4.2, LG build L - exactly the same as offered to you through the lg-firmware-rom.com site.

From what I know there is 10N as well, there are ROMs based on this in here, but I think the completely stock ROM cannot be rooted.

This 10L build can be rooted using PurpleDrake (requires PC).

I would assume that this site is an official one.

If you are not on 10L, flash the 10L ROM using LG Flash tool, root using PurpleDrake, install TWRP.

Afterwards you can install a 10N upgrade (bumped ROM) if you require, or switch to Android 5.0 using 20x ROMs (currently 20C).

The full nandroid backup is a given. If you decide to switch to 5.0 but might want to go back to 4.4, make sure you backup your modem.

The 5.0 ROM threads should have info about this.

Bump:

As the G3 bootloader is not unlocked (yet?), devs have found a way called 'bump' to self-sign the boot image (kernel of the ROM) so they will boot even though they are not LG signed.

Rooting and installing recovery do not change the kernel, no Bump required.

Flashing a new kernel, the files usually come pre-bumped, nothing for you to take care of.

Playing around with a stock kernel (like patching values) instead will give you a "signature error" and not boot. Once you extract your kernel image, bump it and flash it back, you could also play around with it.

OK

I jumped the gun a bit,

From what you said above I have Version K

But now I have Rooted (purple Drake)and put on the TWRP Custom Recovery on

But Now as you say I should probably upgrade to 10L. Do I have to do what you said above and re-root and put the custom Recovery back on again, or is there some other way of flashing it from the custom recovery? Will I lose everything ?

Dam... I should have waited for your reply!

As soon as the lg logo shows up it shuts down again and then repeats. So some kind of hardware issue.. Has anyone experienced something like this? Help please!

Why I cannot use my G3 for usb tethering to any linux distro

When I tried to do that, it works for around 20 secs and then it disconnects, after re-enabling it ir works for 5 secs more and crashes the internet interface on the linux machine, weird enough it works perfectly on any windows machine I have tried.

Steps to reproduce:

1.- find any linux machine or boot yours with a live-usb

2.- connect your phone via usb and enable usb tethering

3.- it will crash after some seconds

LG G3 [ROOTED] OTA Update

Hi,

Realized months later that I have recieved OTA Update, yet as my phone rooted, I could not install it.

I did not want to unroot and update and root again. It seemed quite risky to me, also im a little bit lazy too.

So had to find a way to update my phone without unrooting.

Did some research and find out the "FlashFire" which was tested on only Samsung & Nexus. But installed anyway.

So, of course I have failed to use it~I'm quite rookie~. Couldn't find the OTA update file.

I was hoping that if there anyone had his/her phone updated like the way I wish. Hope you can show me a way to update my phone without unrooting.

About my phone

Just want to ask a minor question

Can one use g3 as usb storage on PC "without" battery in?

I'm fixing my water-damaged G3, and the screen is broken

I'm trying to do a minimum boot test with just the motherboard and usb cord

Didn't know if I need the battery to get my files or not

Thanks in advance.

Can anyone help me with rooting my g3 on lollipop? I've tried every method I could find and nothing has worked. The only option I haven't tried is flashing back to KitKat and rooting from there but if I don't absolutely have to do that I rather not. Thanks
[G3 Q&A, Help & Troubleshooting] engmia:
I'm almost certain that it won't boot but nothing hurts in trying. Also you can press and hold the battery against the terminal ends, no need to reassemble the phone.

Good luck fixing that water damaged phone, I dropped my one in the toiled bowl the other day -- yes I know stupid and funny, feel free to enjoy and luckuly everything is working fine here! I just have minor water marks under my display which I'll try to remove soon using heat and potentially Isopropyl Alcohol.

And remember the golden rule in fixing any water damaged electronic, rice is good for eating, not fixing your electronics.

No you'll need to downgrade and root from there. It's not that hard I promise, but you do need to download the large KDZ file.
[G3 Q&A, Help & Troubleshooting] jerry855202:
I already did the Alcohol treatment, and I can feel the phone booting up and functional (I could see the led breath red, and blue/green when I start up, and the boot up sound, it seems to stuck on boot though)

However my display is broken, and I can't find a way to get my file out without any on-screen cue.

I had TWRP, but it's quite impossible to blind-boot into recovery.

I already got a new phone by now, any idea on how I could get my files out without display? Thanks

D851 phone running stock lollipop

I had an issue the other day where my WiFi and Bluetooth were refusing to connect and just said "connection not allowed" so I tried a few things and then resorted to a factory reset.

Luckily the factory reset fixed the WiFi issue but now another issue has come up, an almost endless boot loop.

Occasionally the phone will actually boot but it never stays on for long even when plugged in. I've tried factory resetting again but to no avail.

Prior to this issue my phone would have the occasional random reset but nothing too frequent, my battery is relatively new but I'm not ruining out the possibility of a faulty battery and am in the process of getting a replacement.

Does anyone have any ideas what this issue could be caused by and how to fix it? The fact that it occasionally boots makes me think it IS a battery issue but I'm a complete noob to this kind of thing.
[G3 Q&A, Help & Troubleshooting] engmia:
Yes, you can "blind boot" into TWRP by:

1. Switching off the phone completely

2. Press and hold the power button and the volume down button for 5-6 secs

3. Release and immediately start holding the power down and volume button for 20 seconds.

4. Click volume down once and click the power button

5. Click volume down another time and select the power button again.

At this point, you should be in TWRP and when you plug the computer in the USB port it should be getting recognised allowing you to transfer all your data. If it didn't work, just modify the 5-6 seconds by increasing or decreasing a bit.

You can also use ADB to transfer the files.

Sounds like a battery issue to me as well, although it shouldn't be happening to a brand new good battery.

Hopefully it's not the hardware bootloop issue that many people are experiencing when using the phone heated up/overheated (which is not that hard to do for the G3 really).

Test out the new battery when it arrives and report back.
[G3 Q&A, Help & Troubleshooting] Scidadle:
So the battery fixed the boot loop issue (I think) but now it's not letting me onto the WiFi again. God this is so annoying

Would flashing a custom ROM potentially fix this issue?

EDIT: Now the phone seems to be working (Without wifi/bluetooth) even with the old battery? Really confused here at what the problem might be...
[G3 Q&A, Help & Troubleshooting] engmia:
I'm sorry I don't think that I follow. You installed a new battery and your WiFi stopped working?

I must be misunderstanding something because this is quite improbable and next to impossible.
[G3 Q&A, Help & Troubleshooting] Scidadle:
When I got the new battery the phone started booting again regardless of which battery I used but the WiFi still refuses to work. I've noticed on occasion the wifi will turn on for a brief moment but then the phone is thrown into boot loop until I remove the battery
[G3 Q&A, Help & Troubleshooting] engmia:
Ah okay, and prior to the issues occurring, had you installed any updates to your software? Were you running fully stock?
[G3 Q&A, Help & Troubleshooting] Scidadle:
Nope. Totally stock
[G3 Q&A, Help & Troubleshooting] engmia:
Fully stock and no updates? You can try reflashing but I don't think it'll help.

This sounds like a hardware problem. It might be worth cleaning the connections and reconnecting the wireless module, making sure it's tightly in place (tutorials about doing this and disassembly around the web, I think iFixIt had the G3 as well).

Or it might be the "bad soldering" issue plaguing some LG phones and users that tend to run their phones hotter. In this case, you can try placing a thermal pad on the chip below the Camera to apply pressure. I can't remember the correct thickness for the thermal pad but you can find information around the forum.

The problem lies with the Wifi IC of the phone.. i've Been facing the same issue on my G3 F400S for quite some time now.. Apparently your previous battery's temperature surge (due to continuous Bootloops) fried up the antennas on your device's wifi IC in the process.. there doesn't seem to be a proper solution to this issue as it is hardware based..

However, few people have tried to develop workarounds for this issue

Does the FM Radio app in Lineage OS 14.1 work on the D850? I know it doesn't work on Android, just wondering if it's hardware disabled or not.
[G3 Q&A, Help & Troubleshooting] Sebbass:
Should lack of stock or CM updates be a concern for security?

I don't install things outside of the Play Store (besides the ROM itself which is CM).
[G3 Q&A, Help & Troubleshooting] engmia:
I'm not aware of issues on main Android.

On the LineageOS the FM App works flawlessly. Music starts playing with fairly good quality as soon as I plug my headphones in. FM stations are successfully scanned and you're a presented with a list of the available radio frequencies, and once you visit the FM station, it also remembers the name in the list.

Tried a short recording also, which also seems to be working well!

Having a phone updated to the latest version generally brings the highest security standards around. New security updates are usually closing old loopholes, but might be opening new ones.

Do NOT considering installing applications from the Google Play Store as being 100% safe. While applications go through review processes there, just by the sheer number of applications among other reasons, sometimes apps pass through. In history there have been quite a few places where malware has been distributed through the Google Play Store (actually this is quite often the case, a hidden app in the GPS, since it has mass coverage to users, people have finally learned not to install apps from everywhere).

So for better security, don't rely on the app just being on Google Play Store. Judge the developer, is he a reputable known name? Do other companies stand behind the product? Which ones? What are the interests of the people involved?

Does the app require permissions with little to no explanation that doesn't make much sense? Do NOT install it.

To stay safe in the web, there are more guidelines to follow, but this applies to all software. Be careful what you download, where you download it from. Always consider, "Do I really need this?".

Very often malware is distributed through basic/moronic/gag apps that don't offer much on the table in the first place. E.g. There have been hardly a case of a "Photoshop grade" program (think an app that actually brings a ton of functionality) that has distributed malware. This is due to a plethora of reasons, that I don't want to get in now.

Or apps that are already skirting what you shouldn't be doing -- e.g. hacks, cheats, cracking programs etc. Torrenting websites for illegal content are often a hub for distributing malware.

Among other rules. I haven't been using antivirus software for years. I've never (knowingly) had an account compromised, hacked or anything similar (a friend of mine actually caught real ransomware -- the attackers had encrypted his data partition!). No unknown logins in my Social Media websites and etc.

[G3 Q&A, Help & Troubleshooting] engmia:
Yes, if you are having battery problems on an electronics device, replacing the battery solves the problems. Just nake aure you confirm your problems are indeed coming from the battery and the motherboard.

It's near impossible to give an estimation of the life cycle of a battery due to the plethora of factors that go into the calculation. I'm not going to into detail into those factors now, if you are interested there is information around the web. This is why batteries' expected life is measured in recharge cycles -- most modern Li-Ion batteries (including the ones in your smartphone) have around 300-400 FULL recharge cycles before the capacity halves.

If you are noticing very diminished life cycle of your battery after 2 years -- yes it's completely possible and expected from most users.

I've never heard of swap space on phones, and I don't imagine you'll get much benefit from this (phones usually have enough RAM on them -- you'll see your G3 at full memory usually but this is by design of the OS and intended, it doesn't mean the device is short on memory).

If you still want to do this, I would recommend getting one of the new SD cards that are certified for apps (faster transfer speeds than class 10, not sure if they are out in the market yet though).

[G3 Q&A, Help & Troubleshooting] engmia:
Yes, you can use the G3 without a SIM card, just don't expect any of the functionality a SIM card brings, like phone calls and mobile data.

If you're connected to a wireless network you can use voice over IP programs to do voice calls.

[G3 Q&A, Help & Troubleshooting] SOCOM-HERO:
Looking to go back to stock after having issues with 3G connectivity on Fulmics 7.5. I've not been able to get 3G working since fulmics 6.0 and wanted to try something in the hidden menu to see if I could get it working again. I toggled something in the hidden menu that I shouldn't have and now I only can use the phone on 4G. I am a VS985 user.

This is not the standard LG hidden menu afaik. I have to go to settings>general>fulmics tweaks>advanced>hidden menu. I changed something in the LTE bands as well as modem to try and get 3G working again. Didn't work. However, I did get 4G working fine again, so at least I can still use mobile data/calls in most all areas. I have been told to reset the phone to stock using KDZ/TOT method, but the instructions are pretty lengthy and I haven't ever had the need to reset the phone, so this will be my first time doing this and I don't want to brick the device!

What are the correct series of steps to reset the phone to stock? Once stock I will then test for 3G connectivity, eventually root again and go back to Fulmics 7.5 to see if I can get the ROM working with 3G and 4G the way it was intended to work. It really is a great ROM and I love it, but not having any signal in low signal areas is a killer for me. I have tried other ROMS and nothing fixed the issue since I made the change in the hidden menu.
