Ok, so lets start with hello you wonderful smart people
I did something very stupid and I'm really hoping there is a solution to my foolishness.
I have an LG G3 LS990, I had previously rooted and all was well. However, I decided I would flash a custom ROM after staying up all night. And in doing so I managed to take the steps terribly wrong, and I formatted the phone completely.
Along with this, I didn't realize at that moment that the phone was being it's finicky self, and had decided not to register as connected through ADB, and only connect enough to charge...
So, I've looked at pretty much everything that has to do with unbricking an LG G3 and it seems that without USB connectivity, I am pretty much boned. But I still have hope.
Basically where I'm at now is, I can turn the phone on, but all I see is the LG loading screen and nothing else happens until the battery dies, if unplugged.
I can use the volume up + plug in micro USB to reach the firmware upgrade screen, but I am unable to make either of my computers (windows 8.1 laptop/windows 10 desktop) register that it's connected through USB.
From what I can tell, the volume down + power, release at loading screen, repress volume down + power method doesn't seem to do anything besides turn on the phone and freeze at the loading screen.
So what I'm asking, essentially, is: Is there a magic method of making my computer recognize my shell of a phone that I haven't seen? because once I can do that, the firmware upgrade stock flash option becomes viable.
Thanks in advance for any help you guys and gals can give.

Hah! I did this once not too long ago on another LG device. Easy to make a mistake when you're tired.
You'll need to use the key combo to get to TWRP (should be Power + Down). TWRP is capable of transfer through ADB and it will also recognize an external SD card if you put one in it. That would eliminate a few steps with checking drivers and such. So you can then move the ROM and Gapps to the internal SD card and install from there.

Thank you for the response. It's a surprisingly easy error indeed. Since I posted this, I figured out the key press you mentioned and have been trying ROM after ROM intended for my phone specifically, yet all of them will end one of 3 ways.
I get a black screen with itty bitty little text saying fastboot mode and restart.
I get everything ready and I boot up, it loads until about the wifi set up and then it will either freeze for a couple seconds and go to a black screen which requires a battery pull.
Or, I get a bsod with the options of volume up = dload and volume down = reboot.
So far I've tried candy5, CM 12.1/11, blisspop, paranoid android, cloudy, and dirty unicorn.
Not sure what I'm doing wrong with these. I use TWRP to wipe everything except external sd, install from there, reboot, and repeat.
I fixed it!! thanks to http://forum.xda-developers.com/sprint-lg-g3/development/rom-stock-zv6-base-odex-deodex-t2949087
this ROM is the only one I could find that worked. I'd still love to be able to upgrade to L but it seems like all of the 5.x roms crash during setup. Not sure what this is due to, but I have a working phone, so I'm not too upset by it.
If anyone has any info on why all the lollipop ROMs are having trouble on here I would appreciate it much.
Well it WAS fixed.... All was fine and well until there was a software update, I clicked install, it tried to reboot, and now I'm stuck in a custom recovery boot loop. I still can't connect to either of my PCs by USB and using my SD card to flash ROMs isn't doing anything now, just boots straight into TWRP every time, after full wiping and re-flashing several times now I'm really not sure how to fix this one.
Update:
Got past the bootloop from another thread on here which had a flashable fix. Now that I did that I'm actually able to use 5.x ROMs it seems. Currently working on Blisspop 3.5, once I get GAPPS to flash correctly, I think I aughta have a working Lollipop phone
Make sure you are using the correct TWRP for your device, having Bumped, as needed. Also, make sure you use the correct version of Gapps; it matters based on the version of Android your ROM is based upon.
Good luck and enjoy!
Good points. From what I can tell I have gotten everything to remain stable now. Blisspop 3.5 and the CM 12.1 GAPPs from http://wiki.cyanogenmod.org/w/Google_Apps seem to be the winning combo. The GAPPs that was listed in the Blisspop thread as the "best" seems to be the reason that my previous flash attempts were crashing upon boot. It might be one of the 86 different apps that were included in there rather than the simple 12 of the CM 12.1 GAPPs.
Either way. I've had no issues now except for the previous issue of USB debugging simply refusing to work. I have installed the latest drivers for LG devices and have tried every article's suggestions I could find on how to make my phone be recognized. I've also tried a few different root required apps that are supposed to fix issues of USB connections. None of them seem to do anything. I've also tried different cords, different plugs and different computers. But it seems like the only kind of USB recognition for my phone is when it's off it can charge. It won't charge while it's on unless I've charged it a minimum of 2% while it was off (regardless of the current battery level) and it can't be recognized as a USB device at all.
Any advice for this? Thanks in advance.

It seems like the trend with ROM publishers is to not update some of those details in the threads; in the VZW variant, I know the BlissPop title still reads 5.0.x when they have been on 5.1 for some time.
I have tried a bunch of packages and have been using the Slim Gapps zero package + the DPI mod for a while now. They work great; there is even a tutrorial on how to roll your own if you like to have somewhere between 12-86.

Some troubleshooting questions:
I think your OS may not supported for Android SDK. Have you ever had it recognized on these machines through ADB before? Windows takes like 5 years to get to the point where most of the drivers work.... I know it's possible in Win7 at this point, but I wouldn't expect it to work in 8.1 or Win10. Someone else who uses it may be able to help with that.
What are the driver's requirements? These are more variables associated with Windows...
Have you enabled USB debugging in the ROM, via the Developer menu? Many ROMs still have this hidden by default.
What version of the Android SDK/Studio are you running?
Have you added the platform-tools to the SDK, as required?
Can you get ADB to recognize the device when you connected and are in TWRP?

Thank you for the response. I have noticed that a few small things are not so frequently updated in the copy/paste updates of the ROM threads. But that's to be expected =P Anyways, to answer your questions:
What are the driver's requirements? These are more variables associated with Windows...
I'm not entirely sure about this one. I know I found the drivers on the LG website for my LS990 model and I also installed a few others including older/latest/various models to test if any of them would work. I'm running windows 8.1 currently and the ls990 seems to have a little less support as the PC suite for LG doesn't include this model in their driver list.
Have you enabled USB debugging in the ROM, via the Developer menu? Many ROMs still have this hidden by default.
Yes, it's been a long running issue on stock, stock rooted, and blisspop all with debugging on. I was able to connect to both of my computers for a long while until one day it just stopped. It was much worse than it is now. For a few days, then it decided to charge up to about 4% when I plugged it in with no battery and then put the battery back and waited for about 3-4 hours. Then I could turn it on long enough to selectively power down and it would then charge while powered off. Over the past couple days I've been able to plug it in and reboot to get it charging again... So bothersome. As for USB debugging, not sure when it stopped exactly but I assume it was around the same time (2 months ago)
What version of the Android SDK/Studio are you running?
I have the latest version of android studio from their website.
Have you added the platform-tools to the SDK, as required?
Yes, I believe so. I'm not 100% on the SDK stuff.
Can you get ADB to recognize the device when you connected and are in TWRP?
No. There is no response from my computer at all during any of the stages of driver and twrp and studio installations. Nothing is listed in my device menu either.
Beyond this, today my phone ran out of battery while I was out and about and then has refused to charge by any method. Then I finally got it to turn on to power down etc so it would charge about 3 hours later. Once I was able to boot back up I went out to smoke and came back to my phone somehow automatically flashing a different version of blisspop that had something about user_modified in the file name which then unloaded all of my saved layouts and whatnot. After about 20 minutes of reorganizing it went black, and has since been locked in a bootloop which has survived full wipes and re-installations of the previous version of blisspop I had been using. I just downloaded the latest version for ls990 once more, and I'll report back with whether or not that fixed the issue at hand.
Hello,
I know you're probably thinking, "omg another note bricked thread". Yes, but I spent many hours of research and couldn't find a thread with my exact problem.
A little background:
I rooted my phone and everything was fine and dandy. I let a friend borrow my phone for a minute and they decided that it would be funny to uninstall google play. I installed the apk from online and had nothing but problems. The app would crash as soon as i started downloading anything. I looked into solutions and did everything from editing the host file to wiping the caches. Nada. The "solutions" just caused other errors. I decided to wipe and reinstall from my backup.
I realized after that because Google Play is a system file, my restore was useless. I decided to wipe everything and reflash the stock firmware with Odin. I downloaded the right one for the verizon model on 5.1.1. Odin sent the file to the device. Just before finishing there was an error and the phone rebooted anyway.
Upon booting the phone now lacked an OS and gave the "use the verizon repair assistant to reinstall the operating system" message. I tried the software (from a friends s5) on 3 different computers and it wouldn't work on any.
I figured, no problem, I will just reflash to stock with Odin again. Only this time my computer no longer recognizes the phone when I put it into download mode. Ive installed and reinstalled the drivers, changed the order of connecting the cables, and when the phone is booted. Nothing works.
The phone can only boot regularly (but lacks an OS) or go to download mode. Recovery doesn't work. Any ideas? Help would greatly be appreciated as the nearest phone repair center is close to 40 miles away
Tl;dr
Phone doesnt have an OS, can boot to download mode, but isn't recognized by computer. The basic troubleshooting steps haven't worked.
Hi urban.. I'm not to technical, but was reading your post. I hit a little confused... Your using the s5 Verizon recovery, not Odin image right
Also try uninstalling the Windows drivers and reinstall after you connect to computer

I tried the verizon recovery for the S5 (I don't have it for the note) and the software wouldn't load. Originally I reflashed the phone with an Odin image but now Odin doesn't recognize the phone.
Yup, I've tried that many times on different computers. Thanks though.

Had a similar experience myself. I also tried using the Verizon update/repair assistant for another device and it did not work. I ultimately ended up borrowing a Note 4, installing the upgrade/repair assitant from that phone onto my pc (enable USB autoplay, then choose to install the software that runs when you connect the phone). The software installed from another Note4 was able to repair my phone without issue.

Interesting. Was your computer unable to recognize the phone as well? How did you borrow another Note 4? I have scoured the internet and haven't been able to find the software online. Would you be able to PM it to me? I would greatly appreciate it as I do not have immediate access to another Note.
ODIN can be finicky with USB cables and ports. Try switching cables and make sure that you're on a USB port that comes straight from the PC and not a hub.
Try uninstalling the Samsung USB driver, reboot the computer then reinstall.
I'm not sure why you were using S5 software when Note 4 is so readily available. I'm not sure that I can recommend using the Marshmallow firmware yet in ODIN. I would use the 5.1.1 version and do the full firmware flash.
what i've done.
Hello Urban415, earlier today my phone decided to take a dump as well gave me that same message with the yellow triangle, i had flashed a bad image (file name : N910VVRU2BPA1_StockRestore.tar.md5) which then gave me that problem.
//-=-=
I went onto Sam Mobile's site, created an account(its free! to download the firmware, it's needed.)
I had to download N910VVRU2BOG5 - 5.0.1 (it took me 2 hours to DL off their site :\ due to free account... but whatevs)
In order to bring my phone back to life also the version of Odin i used was 3.10.6..
My phone was rooted as well and was using N910VVRU2BPA1 - 5.1.1
//-=-=
Hope this helps ! My note 4 Model # : Sm-n910v, bought refurb off ebay.
P.S. Excuse my grammar, punctuation, etc, etc. Also! running Windows 7 x64 and Verizon's assistant didn't work for me either. not even on my windows 8.1 laptop =x!

Glad that you got your device to work. Thanks for the information about the Verizon assistant software. Guess it's not just me.
My problem isn't the firmware and finding it online. My problem is that my computer now refuses to recognize the phone as a usb device. I have tried the usual recommended troubleshooting steps to no avail. Did you have this problem?
I'm reaching about as far as I can go, but: did you try to do a factory reset in recovery? I had that work in freeing up a connection issue in ADB once.
@Urban415 I was googling and found one guy who had a similar issue as you... It was for an older device. But what he did was uninstalled the assistant. Then plugged in his phone and reinstalled the software and it installed the correct drivers... Also I'm not to android savvy, but just a thought. If your using the s5 assistant wouldn't it have to download a note 4 image for it to recognize it. Maybe that's why it's not working. Because it doesn't have the note 4 drivers and image??? Just a thought

Just saying this on top of my head but I have seen system images for the system itself and another with the firmware included. Maybe try the one with the firmware included?

Hey, sorry it took so long to get back.
As I recall my phone was not visible to ADB or Kies while it was displaying the Verizon Repair Assistant screen erreor screen. I suspect that in that state, only the Repair Assistant is able to talk to the phone.
I ended up waiting for my wife to get home (she has the same phone as me) and borrowing her phone to install the assistant software. The software recognized my phone, though it took a minute or two, even though Kies couldn't see it. The assistant downloaded the firmware and flashed it. Phone good as new.

similar thing happened to me but on my 2013 nexus 7. I had to download and use "Minimal ADB and Fastboot" and manually (using Commands within windows command-line-interface) restore my device while it was in "fastboot mode". prior to that tried using "WUGsNexus Root ToolKit " which help instruct the user; with screenshots on how to uninstall drivers that might conflict with one another with the use of another program named "USBDeview". that didn't work for me unfortunately . but for i cannot for sure say if its a "Maybe my windows need a refresh/clean slate" or I missed a step.
Thank you to everyone that helped me in this thread. After trying several new cables, uninstalling and re-installing drivers, rebooting, and playing around with software compatibility software, my problem has been solved.
I have now reflashing stock firmware, rooted, and backed up the phone. Cheers!
Hello everyone. So I have this old phone the LG Nitro p930 that I wanted to root and set up for my toddler. I can see from reading a lot of different threads that this phone pretty much sucks for that but I can see it's still possible.
Unfortunately I can't really dive into this because I'm having a problem getting the phone recognized on various Windows machines.
I've tried on Windows 8.1 I even tried booting up an old Windows XP. I've tried installing the traditional drivers and even updating the Google driver to see the correct ID and use that.
Unfortunately nothing I do allows the Android debug bridge to see the device so I can start trying to use one of the various tools to perform the root.
oddly enough even though Android debug Bridge was not seeing the phone the LG software saw the phone and updated it to 4.0.4.
So any thoughts? Anything I may have missed? I definitely don't mind diving in and getting my hands dirty but unfortunately I can't do that until I can get past this haha
I've been trying to figure this out for a while, and I have made some headway but I think I need to make custom build. If anyone could point me in a direction, it would be super helpful. I have a few ELO ESY15i1 android computers. They are EOL now, and only supported up to kitkat. ELO does not release their kernel source, but I do have their peripherals.
This is how far I have got with this thing, and what I was able to do/determine.
After a bunch of digging, I'm pretty sure that this thing is just a modified S4 i9505. Hardware specs seem to match, outside of the CPU only being 1.7 instead of 1.9ghz. I'm *assuming* that they have down clocked it maybe? The first unit I was working with, apparently had a bricked recovery (had bough it 2nd hand). I was able to boot it into TWRP using the jfltexx image, but I would get no picture. I know it was booted because I could access TWRP via cmd, and it was giving me responses back.
I was able to root it in a very round about way. Since I do not have any volume buttons, I'm limited to adb etc. I was able to root it with iRoot, convert that to supersu, and eventually get flashfire to install. I could finally access almost everything I needed. At some point, I got it stuck in a mode where "QHUSB_DLOAD" was shown to me, with a folder called "image" which I took a copy of. Any google results with that, was just people who had bricked their device, I was able to boot in and out of this, so I'm not sure what was going on or broken.
Here is what the device props listed out: hXXps://pastebin.XXX/FtgQ0DUE
This is the mobilodin report: hXXps://pastebin.XXX/BZrDAFg4
Finally, the "image" I copied: hXXps://anonfiles.XXX/lcQ7RfJ8o0/ESY15i1-image_rar
(sorry can't post links)
The first unit I was working on, I gave to a buddy to mess around with. The 2nd one I have, I have now bricked and it is officially stuck in the "QHUSB_DLOAD" mode. I made a poor choice, and modified the i9505 "updater-script" in lineage-17.1-20200723-nightly-jfltexx-signed to include my "msm8960" device. I flashed it via FlashFire which did go through, just bricked me in the process.
I had a samsung download jig, but I can't find it anywhere, so I have a new one on order. I'm too lazy to cut up a micro usb plug and make one. I have yet to get odin to recognize it at all, or get it into download mode. When I try over adb, it will reboot, try to go in some mode, then reboot again back to the rom.
Any input / help would be greatly appreciated. These machines are super cheap on ebay, the only problem is being stuck on kitkat. I can think of loads of things to use these for, doesn't look like anyone has tried to do anything with them. From all my searching I just found one guy who was trying to root one, and that was about it.
Hi,
I have one 22 inch unit, which I'd like to use with monitoring system and some else, but I need android version with multi windows support, so I'd like to ask you if you succeed with installing new ROM ?
Thanks in advance for reply

Well, I've been dinking around with it again, I think I have the HW figured out. I'm pretty sure it's an LG Optimus G, LGE970 is what I'm trying.
I was able to take the stock "ATT-Stock-E97020j" non KDZ zip, pull the boot.img off of it, and flash that.
Now when I connect to my computer, I'm getting LGE Androidnet for Diagnostics, and LGE Androidnet USB serial, as 2 devices.
Just keeps hanging right away when I try and flash the KDZ.
Greetings,

I've been all over the Internet trying to gain access to more information about how to repair my LG G4. Well... Let's start from the beginning.
Story
I have an LG G4, it's old and I've had it for over 4-5 years now... I can't exactly remember how long I had it for. It still works, just needs a new battery and cable (cats chewed the cable and batteries don't last when you forget to disconnect them from the device, leave it plugged in for weeks and let it completely die for longer then a week).
I recently saw a video about the Pine phone and the fact that it was able to run a linux mobile distribution and when I looked into installing a custom OS into LG G4, it was possible... If I manually ported it myself.
I actually got fairly far using my Xubuntu system with configuring and compiling, the trouble I ran into was that I couldn't root or fastboot my device.
So, now here's where the problem began, I have a LG G4 factory reset and when I load up the Recovery mode, it brings up the android guy with their chest open and an exclamation mark in a yellow triangle, no message. After attempting to boot into recovery mode, I wait a little while and the phone automatically resets back to normal. When I use ADB to force the phone into fast boot, it skips it and starts the phone normally.
Now I'm on a mission to find a way to either fix the boot or flash the firmware (in hopes that it fixes the boot/recovery).
I have already tried:
Installing LGFlashTool
Versions, 2.0.1.6, 2.0.1.9, Year: 2014 and 2.0.2.5. Other than year 2014, the other ones were installed from LGFlashTool.com
Since Xubuntu can't run these files properly, I just ran them on my wife's Windows computer
I installed the LG Mobile Drivers and LGFlashTool had registered that it was the correct DLL but, it didn't seem to find the phone
Year 2014 LGFlashTool had found the phone but, I may have had the incorrect kdz file.
The Flash starts and the phone goes to firmware update, but the phone stops at zero and sits there while the program crashes saying that there was an error (in which no means to read, understand or locate the description of this error) and to try again by unplugging and removing the battery.
This version was downloaded from xda-developers.com
Conclusion
Once I can get into fastboot, I'll be able to root my phone and attempt to install the mobile OS I have ready.
Otherwise, I think I might be able to install a microSD card with the OS but, I don't think that will work if I can't get into the option to boot from a separate location (I believe that's called fastboot). But, then again... I think the phone needs to be rooted first... Then that brings me to the previous issue.
Details and Information
The phone details (as far as I see) are:
When I remove the battery I can see:
FCC ID: ZMFH810
IC ID: 2703C-H812
Model Number: LG-H812
I'm not exactly sure what KDZ file I got but the name is: PR H810PR10a_02.kdz, I also have the _04.kdz
I'm using H815 as my compile for the mobile OS, I may switch to H810 when I get back to that point.
Useless information: I still have the original leather backing... Removed from the phone because I didn't like it. If I find it, I can ship it to someone.
That's about it... I am very terrible about research and using Google properly (I have no idea why, I think it's a terrible flaw to have but, I have it). So, if you find the solution by typing words I didn't use or finding a similar post, I am very sorry. Hope I have everything posted here to help solve the issue, linking to posts that can resolve the issue or posting questions on what I might be missing will help.
Thanks in advance for the support of this community,

I've been all over the Internet trying to gain access to more information about how to repair my LG G4. Well... Let's start from the beginning.

Well first of all you need to unlock your phone. H812 can't be unlocked officially though. Check my sig for the only unofficial one. Once unlocked you can flash custom ROMs but first of all you should read about ARB (antirollback) also in my sig and ensure you understand the risks all this brings. Gl.

Thanks for the positive feedback, I will attempt to fix my phone with your solution. This phone is technically almost garbage and when I fully update the phone, it runs like trash. So, if I can install a custom ROM, it may run a little better or have the tools I would personally like in a phone.
I'll let you know the details of my attempt,

It is more reliable then the factory tools when it works.

Which is included in mAid (https://maid.binbash.rocks).. ... Even with a UI...
Thank you very much with your support. I was able to unlock, bootloader and install the image installer.
I'm on the verge of compiling and installing Ubuntu Touch on my LG G4 H812.
Hope you guys proceed with everything you're doing right!
