A question from G4 noob - G4 Q&A, Help & Troubleshooting

Hello everyone. I am currently using LG G2. Which is easy to manipulate with roots roms etc.
But my question is about G4 of my girlfriend. I wanted to flash a custom rom to it. Started researching and come up with a lot of mindboggling information about bootloader locks and bricks and some country restrictions. My head spinning.
What I need is a guide for a noob about flashing custom roms from the beginning.
Phone is LG G4 H815TR

[Q] LG G3 US990 CM11/12 ROOT help

I recently bought the LG G3 after having switched carriers due to coverage issues, From Sprint to US Cellular. I've had the Samsung Galaxy S5 for a while, I got it when it first came out. I just recently rooted it and installed CM12 on it and I'm in love (My S5) and now I really want it on my beautiful G3, but I haven't the slightest idea how to root it, or even remember how to do it to be honest. I've googled and I've looked on here but I guess I'm looking in the wrong places.
My first question is, has anyone successfully put CM12 on a US990 LG G3? Secondly, what if I were to use the d855 CM12? Would that have an affect on my phone? I'm assuming it would, so I'm not taking any chances.
Lastly, what's the order everything would need to be done in?
For example
Root
Custom Recovery
Back everything up
Install Custom Rom
?
I really don't remember much about doing it to my GS5, it was (if I remember it correctly, if at all) rather painless when I got the hang of it.
Thanks for any help! Have a good day.

New to G3: root, unlock, ROM specific to carrier?

I'm not new to rooting, bootloaders, and ROMs, but I am new to the G3. My current phone is a Nexus 4 on Cricket (AT&T), so of course everything ROM related couldn't be easier. I figure the G3 will be "harder" by virtue of it not being a Nexus device. My D850 will be here in a couple of days and I want to hit the ground running with a root and bootloader unlock. After poking around, I thought it would be easier to ask the community where to start and what steps to take.
1.) Root: I see that Stump is no longer supported; will it still work or is it because LG has patched the exploit? If the latter, is there an alternative root method you recommend?
2.) Unlocking the bootloader: I see Bump! Is this a "true" unlock (ie. I can install any AT&T ROM variant) or do I have to use specific Bump ROMs after installing TWRP? Is there any other (better) options?
3.) ROMs: I assume you can only use AT&T ROMs on an AT&T G3 variant (mine's the D850) due to the specific radios. Any known issues with using the D850 on Cricket?
4.) Any thing else I should know about ROMming for the G3? In terms of flexibility, I've been spoiled with the N4, but I'm looking forward to the hardware awesomeness that is the G3!
TIA for any and all responses! I love the XDA community
1) If the phone comes with KK stump should work, otherwise there are several 1-click root methods like this. (see the AT&T specific forum)
2) Bump is a method to sign ROMs and other "bootable" sections of the phone; Yes they must be bumped. Bumping on L also requires a bit of a hybrid KK-L setup, but the steps are all well documented in the various threads.
3) True
4) Proly not quite as much as the N4 but there should be enough to keep u busy for a while

Bootloader unlock and root for H815 v20a-SEA

Hey there!
I've just bought myself the lg g4 h815 and it came with the MM 6.0 android version - v20a-SEA. My old phone is oneplus one and i'm familiar with the usual unlocking, rooting and flashing processes.
I pretty much covered the internet as much as I could but couldn't find any way or method for unlocking the bootloader and rooting my specific version.
Is there any solution for my situation?
I'd like to root my phone just cause of the lame battery life, much worse than my old Oneplus one phone.
Thanks in advance!

Hello, I have the same problem , upgrade to Marsmallow few weeks ago and nothing, the battery will think worse. I read in forums that can be done by Ubuntu but it seems risky. And I'm waiting to get an easier way to do it .

VS986 n00b* Whats important?? -just upgraded from the G2 VS980

I know the Verizon variant of the G2 was different from the others, and from what I've read about this G4 and the Verizon Variant; it has its similar but differences to the others as well? I posted a screen shot of how i received my new phone right off the bat.
Root: I saw the only? root method was a .kdz flash of the 11A? Is this the ONLY way? Because my phone arrived on the 26A which i see most of you talking about just recently getting this update?
Boot loader: Its LOCKED up tight?? So their is no Custom Recovery such as TWRP correct??
Xposed: Xposed can be installed; IF you have obtained root.....
Is this info correct? Only one root method for VS986? and the etc above??
Is their any other important MUST KNOW info on this G4 in general and the VS986 specifically??
Thank you guys.. Hope to CATCH up and master this like the G2..
**PS** I will contribute to the Bootloader Bounty, Ill head over to that thread when i get home tonight....
So yeah the Verizon version of the phone is different compared to the International version. Our bootloader is locked and will likely remain so. This means that if you're running Android 6.0 (and you are with 26A) that means you cannot root the phone nor can you use a custom recovery. This phone is getting a bit old so I wouldn't count on ever seeing the bootloader unlocked.
I had rooted the device last year using the only root method that has been available so far. Root "injection" is what they called it, I believe. Once rooted there is a way to get Xposed framework on there too. From what I've read here on the forums there is a way to downgrade your phone to the older version in order to use the root injection technique. For me it wasn't really worth it though because I felt the upgrade to Android 6 was worth giving up root for.
The phone is pretty much dead. I know Verizon stopped selling it, supposedly due to issues, and I believe AT&T did as well.
You can downgrade to 13B using LGUP.
You can use Debloater on 26A to freeze all the Verizon nonsense.
On last thing. The bootloops is real.

Mine just boot looped yesterday too, unbelievable. I am pretty sure this is why Verizon stopped selling the phone, failure rate was just too high. Looks like most of the early model G4s will fail due to this.
Yeah. Get rid of this phone. Can't do anything with it. I ditched it after a month.

Wow. So there's basically no Roms for this phone because the bootloader can't be unlocked in order to install them? And that's why there are only a couple of threads in the Verizon G4 development forum?
I love both of my $1 G4 phones from BestBuy. Yes I have had the boot loop problem but Best Buy handled it nicely. I believe the bootloader being locked does not stop custom ROMs as the boot loader was locked on the G2 and G3 as well wasn't it? As for customizing the G4 I have mine running beautifully. Debloated and modded with Xposed. I do agree that it is sketchy working without a real recovery and backup being a moment away at all times. For me, I'm going to use my Verizon G4 until it lets me down, but for now I love it.

I'm probably going to just either jump back to a compatible G3 or ahead to a Moto X Pure Edition when it comes time to upgrade next spring. I don't have time for these Verizon shenanigans anymore.

VS985 (VZW LG G3) hardware problems thinking of buying a G4 VS986

I am screwing around with my VS985 G3 but I have random / phantom screen touches and the top 20% of the screen doesn't register touches properly anymore. I just tried doing a factory reset thinking it might be software problem but it still seems to have the same issues (23C) when hard reset. Soooo, I am considering moving up to the G4, but the main thing I don't want to lose is the unlimited hotspot data since I still have the old unlimited plan and use it frequently as a hotspot for devices in the house. So I needed root to install the hotspot mod and want to make sure I can root any G4 I wind up purchasing.
What are the requirements for a rootable G4? Are there firmware versions that are not downgradable via kdz/tot method? Should I ask before purchase for a device that is on firmware XX or lower to ensure downgrade capability?
From what I understand the G4 is the end of the line for unlocked bootloader devices, correct? I don't have any other internet options at my location so the unlimited data through VZW is critical to me at this point thus I can't live w/out the root access on my device.
Any recommendations or help is appreciated!
Cheers,
-Scott
I was hoping someone could just advise about firmware level that allows downgrade? I am reading up on the G4 but not sure yet what version of firmware or > prevents downgrades. My preference would be to buy a phone I can downgrade to 13B and run a custom ROM. Now looking more closely at the "android development" forum for G4 I see there really aren't any custom ROMS for G4. Is this because G4 is a locked bootloader?
In the meantime I determined my G3 screen really does have a problem so ordered a replacement, so I'll try that since I was able to downgrade that to 10B and so should be able to keep that running with custom ROM's until I decide what I want to do to upgrade. I do see that hotspot mod is actually available on G4 with 13B root. I'm just concerned about buying a G4 which won't allow downgrade so hoping to get an answer about that.
The verizon G4 has a locked bootloader so no custom ROMs here, but you can certainly root. I just recently downgraded from the latest firmware to 13b rooted and as far as I know there is no firmware version that blocks downgrading via LGUP. However, If hardware problems is what your trying to avoid than stay far far away from the G4. It has a long history of hardware faults and I personally have lost 2 G4s due to hardware failure.
Thanks Justa. So it looks like I'm just better off sticking with the G3. So far the hardware has been fine, just hoping replacing the screen does the trick.
So I guess everything after the G3 has a locked boot loader?
