After stock KitKat upgrade attempt stuck in TWRP!? :( - G2 Q&A, Help & Troubleshooting

Hi,
I really would need some help, think I kind of did a stupid thing yesterday. :crying:
I bought a secondhand LG G2 d802 a few month back and been very happy with it. I live in Singapore and yesterday I remembered that I had read that LG would realse the KitKat update for LG G2 in Singapore in mid March.
I went in under phone settings and serched for LG updates and it was a an upgrade on around 500Mb. I got really exited and started to download it. After it downloaded it restarted the phone but then open up an app called TWRP, and no mater how I try to rebot the phone it always comes back into TWRP.
What i kind of have understood is that my phone was/is rooted and I guess that didn't go well with trying doing a stock upgrade. I have been using stock android 4.2 so not had any custom roms installed.
My question: is there any way to either role back to my prev version (4.2) or install 4.4 without loosing my data (pictures, don't really care about the apps)?
(I have tried to find where the phone downloaded the update to run it through the install feature in TWRP but can't find the zip file. I can't enable the OTG port in TWRP so not sure how I would be able do run another ROM either)
Hope someone can help me!
Thanks,
Sandra

So it looks like your phone has a custom recovery installed and you tried to install the stock OTA. What you can do is either KDZ back to stock or flash a custom ROM. I would just flash a custom stock ROM. Easier and less steps.
Good luck!

Hi mackster248,
Yes that's correct, that was my thought as well but in TWRP under mount I can't enable OTG usb. So I cant read any ROM from any external source and I dont have any saved on the phone either so how would I be able to do that?
Thanks,
Sandra

You can use the lg mobile support tool to flash a stock rom after going into download mode on the g2 (holding volume up and press power on). Don't flash Kitkat since there's no root option yet.
I don't see a way to keep your pictures though.

You can use the terminal in TWRP to nuke the fota partition and restore normal boot.

Ahhh, I see. You'll have to KDZ back to stock then. I think someone already posted the link, but if you need help let me know and I'll try to see what I can do. I have the T-Mobile D801 so I'd have to see if it's the same process for your D802.

Worked like a charm! Felt like an idiot when this happened to me. Good thing I backed up all data before trying the KK update. Thanks!

i have the same with the one you got and here is the fix for you
Here’s the easy fix:
Method 1: Using ADB access, plug in your phone and run this:
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
Now you should be able to successfully reboot your phone via the TWRP menu option, or via a simple reboot command in adb.
Method 2: Using TWRP’s "terminal command" option to run this:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You’ll have to type that whole thing out, and be very careful with spaces and punctuation. One wrong letter and you could nuke your LG G2.

friend accepted sprints new OTA. Phone wont boot past TWRP

So, I rooted my coworkers Sprint G2 or LG LS980 using IoRoot a month ago and had TWRP installed on it. prior to doing this I had looked into what it would take to revert it to factory unrooted unmolested state. didnt seem to hard with the lgFlash tool and what not....
Well two days ago he accepted and tried to install the new OTA. he was on ZVA firmware, and I believe the new OTA was for 4.4... well the install of the OTA failed im pretty sure do to TWRP being installed instead of stock recovery. instead of stopping there and calling me he tried to fix it himself... I believe one of the things he did was to wipe the device. as in advanced wipe, select EVERYTING including system....
He gave it to me today rather pissed and asked me to fix it.
Ok, I have bee through MANY threads about reverting back to stock, and it seems I am having a serious driver issue... In my laptops device manager I can see the LS980, but it has no driver installed. I have downloaded many different versions of the LG drivers from various tutorials here and on other websites. I even tried to find them on LG.com, but no luck there.
I can get it into download mode, holding vol+ and plug in USB, but once I try to connect to it via LGMobile Support tool or LGFlash tool, they do not detect it. it tries to load three different modems, and the center one always fails. is there anyplace I can get JUST the driver, not the entire self extracting EXE files?
I was just going to copy a ROM onto the internal storage, but even using the mount tab in TWRP it will not connect to my computer.
PLease for the love of all that is sacred to XDA help me!!! I sadly do not know much about ADB... I have never really used it. at this time it is not installed and I wouldnt know what to install and how to ADB Push a rom onto the phone...
Edit, here is ONE of the tutorials I tried, but since I cannot get the proper drivers installed this hangs when I click the yellow arrow to start it....

okay so have you tried the following from this thread-
If you DONT have ADB access (because of an early build of TWRP), you can simply use TWRP's awesome "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.

Ok, I think its TWRP 6.1.3.3? Maybe 6.2.3.3... not sure. Phone isn't in front of me this second. As to the terminal command... do I type the word code first? Or is it just there as part of your sentance, type this terminal code..... yea, I'm a retard sometimes. Thanks for your help.

Yea, I have been trying that method... my issue now seems to be that one of the drivers is not installing correctly. So I cannot change the device to port 41. And the app will not see my phone. When I get off work tonight and can use my laptop again I will try downloading advanced and setting that up and see if I can make it work that way. I also read the other thread that was linked last night looking for the two terminal commands to try, both the fota, and the miscellaneous command... found the commands, typed them in, and now my phone boots to the LG logo and my notification light starts scrolling through different colors. I can still get to both recovery and download mode though, so I am not giving up.
Also in that thread someone mentioned koush's generic adb drivers... I downloaded those and will try that as well.
Basically if I can just get my darn laptop to connect to this phone I think I might still have a shot at reviving it.
Multi color led makes me think, wing kernel. Like installing zvc kernel over zva system modem.
You may have to uninstall all lg drivers, and reinstall
Sent from my Nexus 7 using Tapatalk
Well it was running fine until he tapped accept on the ota so I dont know how he would have gotten the wrong kernel.... I have uninstalled the drivers a few times and reinstalled different versions. There is always one that fails when I plug in the phone. Plus I get a message on the device about mediadata unknown, or not found.... something like that. I know before he called me he tried the wipe option in twrp. I know on my galaxy s4 we were not to use the wipe data command in there, I'm thinking he did...
But I can still get to download mode so if I can get my laptop to recognise it I have faith I can lgflash tool it back to life... if I can get the drivers to cooperate...
Quick update on this... I found a tutorial on using adb and managed to sideload a rom, derp milestone 1 I believe it was, and after it completed the phone booted up just fine. My friend wanted it to be reverted back to its stock unrooted state, so I tried LG mobile something or other on my laptop... you all know, the one where you hit options then upgrade recovery and it should download and flash stick software? Well it saw the phone, and said there was no upgradeable software on it... mind you the phone still has a working twrp 2.6.3.3 on it... I don't know... I tried LG flash tool, but i can't get it to be port 41 for that to work... but at least the phone boots and runs fine now.
Still having my driver issue though. When I plug in the phone windows installs 3 drivers. One is CDC driver which always fails. No clue why.
Any ideas?

Can't flash KDZ? Help!

Hey guys. Here's the deal: I screwed up my BELL LG G2 and the only thing I could get it to take was a TMobile .TOT file. So I did that and it "works" now. Thing is, I get no bell internet now because well... It's messed up. The phone thinks it's a D801 but it's actually a D803. So anyway, I want to get Bell stock back. I downloaded the stock bell kdz so that's not a problem. I have that latest (like last month I believe) KDZ flash tool from LG called "LG Flash Tool 2014". Here's where things get messy...
Step by step:
1) I open the file "LGFlashTool2014.exe" and it opens fine.
2) For "type" I select "3GQCT" (I don't even know what this means to be honest), for "PhoneMode" I select "Emergency" (tried DIAG too and it makes no difference) and for KDZ I select the D803 Bell LG G2 KDZ file I have. I leave version blank as it fills itself in.
3) I select either "Normal Flash" or the other one that wipes everything (neither work....)
4) It then brings up it's second screen and I select "Start" at the bottom.
5) It brings up the third screen asking about language and I either leave it or choose "other country". Both of these options (in the top drop down menu) give me no options for actual languages in the bottom drop down menu. The bottom drop down is just blank. Anyway, so I then select "start" again.
6) The LG Update Tool pops up and does the following:
It verify's my phone's connection, says "extracting software" then "S/W Upgrade is in progress" then it suddenly stops and says "Upgrade stopped due to error." Followed by instructions to disconnect the phone, remove the battery, reconnect the phone, and turn it back on (it's a bloody LG G2 so I can't take out the battery...)
What do I do here guys? I'm seriously confused. Oh, and yeah I've tried uninstalling and re-installing... My phone is in download mode. USB Debugging is on. What the hell else can I do?
I have this same error.
I have s80210a-EUR-xx and Rayblobe ROM (since late last year) , android 4.2.2
I get stuck to that exactly same point "Upgrade stopped due to error."

Firstly, thanks for taking the time to reply to me. I reallly appreciate it (nobody here seems to give a flying.... Well, you know). What exactly is that post you linked saying? Not sure I understand what he means.
BUMP!
Can you boot into recovery?? Try getting that ROM in zip mode and flash it through recovery. It should work.

I'm trying to first flash stock ROM and then go back with the original plan.
Also, I did find "stock kitkat ROM" .zip. But I don't know if you can post links to other places than xda?
I've made my nandroid backup already, so first i'm going to test that kitkat rom. because, if it works, it's much easier

If you mean to get bell stock rom and flash it, I tried. It bricked my phone and I had to do the TMobile .TOT. Now that I have TMobile, I have no recovery and I have no idea what recovery to put on the phone (CWM or TWRP? Bell or TMobile?)... God this is such a pain in the butt... If I ever get the G3 I wont be rooting it...
Alright so I rooted the TMobile rom on my LG G2 (again, it makes no sense because I have a Bell phone). I then installed "Flashify" which can be found in the app store. I found the TWRP recovery img for D801 TMobile LG G2 (you can find it by searching on google) and then I booted up adb (you need to install adb if you don't have it). I put the bellstock.zip (I renamed the file) into the folder for adb and opened adb. I then typed "adb sideload bellstock.zip" (you need adb sideload to be running from recovery on your phone first. In TWRP Recovery -> Advanced -> Adb Sideload). Adb started to very slowly sideload the .zip and I was excited that it was working. Well, it got to 100% and said "Success! Enjoy!" and I was so happy. I hit the reboot button and...
LG Symbol just stays on my screen and the phone never finishes booting. It's not a bootloop though, just the LG logo on my screen with a pulsing blue/green notification light. How do I get past the LG Logo?
Thanks guys...
Just tried sideloading a different version of the Bell Stock rom... It failed. Maybe I should have cleared cache or something first? Anybody?
Try to push roms to your phone instead of sideloading since sideloading is more risky. If youhave a custom removery then did you tryed to format system first? And then installing the rom? You dont need to wipe data if same android version if you still have data on it else also wipe data factory reset and also dont forget to flash the right modem for your stock kitkat/jellybean.

When I try to push adb just re-pastes the whole menu into the cmd window and does nothing. I could only get sideload to "work". And yeah, I have the radio for Bell, I just haven't flashed it yet because I want get rom working first. Also I did wipe everything before installing the rom.

[Q] After 4 1/2 yrs on XDA I am finally stuck! Bricked No download mode, No OS.

Hello my fellow XDA Members. I am stuck in a tight spot and after reading and re-reading some things the situation doesn't look very promising. I hope this is the moment that Karma shows up and I can get some help on this. Here it goes.
Specs - LG G2 D801 Variant > TWRP V2.8.3.1 > NO OS Currently
I was running Cloudy G3 Rom smoothly and got bored and decided to flash that new rom that is a 5.0 Rom all variants. Did the usual back ups and flashed it. Something happened when I flashed the rom. It went through the Aroma installer and then said "successful" but stuck in a bootloop. I tried it again and nothing happened. Then I tried to wipe everything again and started getting an E: Cannot mount (data or system I forget which as that error went away after I completely formatted data, wiped everything and reflashed Cloudy Stock. )
> Cloudy stock bootlooped and nothing is happening in TWRP. I Am using the USB OTG method of getting files on the phone and getting it charged but anytime I try to do anything (flash a rom, an older version of TWRP) it just immediately restarts TWRP and thats that. I have No OS at all.
> I tried to use one of the methods to get into download mode and flash a stock KDZ but the phone acts like it is going into DL mode (shows the little blue transition screen) but never gets into the ACTUAL download mode where the PC or flash tool can recognize it.
So in a nutshell > No OS > I can get into TWRP but it does nothing > No Download Mode > Don't want a new phone > Don't want to take it apart and try to short circuit anything if possible. LOL.
I am totally stuck here. I am done alot of work and even helped friends and family out with their devices over the years. I am just not sure if I need to consider it a done deal and get a new phone or maybe one of you guys know of something easy and obvious (please let it be the latter) I am missing. Thanks for any help you can offer. I Will be standing by.

I haven't thought about flashing a bootloader. How would I flash the bootloader if I can not the phone into either DL mode and or TWRP doesn't do anything either? Is a bootloader file just a flashable file like any other .zip file?

The first one I can not do as I do not have any knowledge at all of Ubuntu, Linux, or any of that. It would take forever to get a working knowledge of that software in order to get things going again. I would probably just have to either take it to a cellphone repair shop or get another phone before I could do the first link.
I have not tried the second one but it is a viable option. I was looking at it online and trying to talk myself down from having to do that. I would reallllllllly rather not have to take my phone apart if I can keep from so that's kind of what this post is all about. Just trying to see if anyone knows of ANYTHING else before I go taking apart my phone.
Can you describe more about "twrp doesnt do anything"?
Does twrp boot up?
Can u see/wipe partitions?
Can u install any rom in twrp? Does it finish?

TWRP boots and I can go into wipe, advanced wipe, and format data and it says it's successful. I can use file manager and move items back and forth from USB OTG. If I try to flash anything it just reboots TWRP immediately so I can't install any .zip files at all.
My guess is that your bootloader is damaged.
The only option i can see for you is that Ubuntu thing i shared with you. So, lets stop acting lazy and do what needs to be done. Dont scare since there is nothing to loose. LG G2 is unbrikable
Booting up ubuntu or any other linux os is so easy. And there is nothing much to learn. Trust me.
Go to ubuntu website and download their newest iso file. Burn it on dvd and boot it up. You dont have to install it, just choose "live mode" and it boots up. Just like that. Then yiu can proceed with tutorial mentioned above and it shouldnt take more than an hour from you. Its all typing some commands in terminal (remember CMD in windows!).
Just make sure to download the files mentioned in that tutorial before proceeding.

First of all calling people lazy is not nice. I'm not lazy I am trying to play it safe. I wouldn't want to brick it to the point to where I don't even have recovery and it can not even be charged any longer. I have Ubuntu on my desktop upstairs. I have used it a little. It's not that I am completely ignorant to Ubuntu I am just a total novice. Also the issue described in that post doesn't exactly match my situation. I am not in a black screen. It's more like a bootloop that I can not get out of because TWRP is not doing what it needs to do and I can not flash TWRP a ROM or get into DL mode at all. Also that post says,
"VERY IMPORTANT!!!!!!! You must use the img files that correspond to the ROM you have installed before getting the problem to avoid breaking your phone."
I don't have a rom on my phone soooo...
You didn't answer my question well. If on TWRP you can finish installing rom without any error, and you keep coming to twrp after restarts, that's another situation. Try this:
http://forum.xda-developers.com/showthread.php?t=2451696
But if you cant even finish install in twrp (twrp gives you errors or just restarts before giving you "successful", either you have problem in rom you try to flash or you need to build everything up from start.
That lazy thing was for encouraging you to do it.
And you cant brick your device. There is always a way on G2.
For img files: find them from last stock rom that was working on your phone.

[Q] Bricked, PC doesn't recognize Download Mode and TWRP sideload doesn't start

Hey guys, it's 4am where I live and I'm becoming desperate now... Hope someone find a solution for my problem and is willing to help me.
I was using the latest CM12 nightly on my new d805 and decided to try the new CloudyG2 3.1. I was told the easiest way to do this is flashing a Lollipop bootstack (which I found here https://github.com/lg-devs/bootstack...master/d802/lp) followed by the Cloudy ROM itself.
I did it through TWRP, and then things started to cramble. On reboot the LG logo briefly appeared followed by a black screen. I've found this topic http://forum.xda-developers.com/show....php?t=2432476, downloaded the appropriated .kdz but my device isn't recognized by my PC. I've tried reinstalling the drivers and using the universal ones, but my computer just doesn't care about the phone being connected or not.
I tried to start sideload on TWRP so I could push a CM12 .zip back to the phone, but the sideload doesn't start, so I essentially can't send any file to the phone. Is there any hope for me? I'd be so happy if someone gave me a solution for this... I really can't afford to buy another phone right now and this is my only method of contact with some relatives.
Huge thanks in advance, this community rocks.

I've tried reinstalling the drivers and using the universal ones, but my computer just doesn't care about the phone being connected or not.
I tried to start sideload on TWRP so I could push a CM12 .zip back to the phone, but the sideload doesn't start, so I essentially can't send any file to the phone. Is there any hope for me? I'd be so happy if someone gave me a solution for this... I really can't afford to buy another phone right now and this is my only method of contact with some relatives.
Huge thanks in advance, this community rocks.

If you can go in recovery mode you could use the usb-otg to flash a rom and reboot the phone

So I need a specific cable to do this? Is this the only way?
You need a normal usb-otg that can find in every electronics shop

[q] lg leon lte h345

I'm in desperate need of a stock rom if anyone can help me out, was fiddling with root access and ended up losing my entire notification drawer and home button and whatever you call the square button. I have twrp installed but no rom.
Also this is a general LG LEON LTE thread because there seems to be almost no support for the phone.
Hey I know there are others or there looking for the same thing, any help would be appreciated.
seriously there are other people out there looking for the same thing someone give us a back up image.

will a nandroid backup do for you? If so i can definitely help you out
i was looking for a link or two
I recently just got back into carrier devices an havent bothered with moddin devices in about two years i own two nexus devices an have sideloaded them for years with corporate emails an only have gone as far as tweakin boot images an on my older droids flashing custom mods daily... My only question remains with these newer junky devices how does one gain su if needed safely for things like otg access. It seems to me almost every carrier device is worth rooting an modding nowadays, an nexus devices are still the only ones that have a program thats stable an universal for all manufactuers as far as updating an management of a os whether it be stock or the user decides to go third party.
With that said.. Thats why awhile ago i stopped modding phones, using a windows tablet (for a full version of msdos) an since i had mastered my PB9110 version of my nexus one, i would flash my images via adb and sideload images with command line, in time ive sampled nexus after nexus, never using (play) an now back to a carrier device with no program support except 3rd party mods... Which in reality is great once you do have a nandroid backup an a stock rom... Thus the ability with the nexus factory image. Where are the steps and how tos my friends????

Hey! I just used a program called Flashify (Found on Google Play Store) to back up both my Kernel (Boot) and System (Recovery) for my LG LEON LTE. I haven't attempted to reinstall these backups using Flashify as of yet, since I just rooted my phone and installed TWRP bootloader so I can try out a ROM... so, I have no idea how it works or if you can use it with any other bootloader app. However, I am attempting to offer you some kind of OEM Backup. I'm pretty new at some of this. I haven't posted enough to add links yet, but I'm going to try.
I have a LG Leon LTE for T-Mobile. My OEM details are as follows:
Android Version: 5.1.1 Lollipop
Baseband Version: MPSS.DPM.2.0.c11-00021-M8936FAAAANUZM-1.19638.1.19833.1
Kernel: 3.10.49
Build: LMY47V
Software Version: H34510f
These downloads are only available until 11/26/2015 due my only having a free account on the hosts site. I hope they help!
Kernel (Boot): OEM 3.10.49 @ http: //sabercathost. com/5Y7 (60 second wait for free download)
System (Recovery): OEM @ http: //sabercathost. com/5Y8 (60 second wait for free download)
Again.. I used Flashify (for root users) free from Google Play Store to create these backups. I have no clue if they can be used by any other programs for recovery. If you have/or can get Flashify, I'd like to believe they can be used for your STOCK recovery.
I may try and make a more common backup of these using ROM Toolbox Pro and see if I can host the files elsewhere that isn't limited to 7 days before paying for premium. If I do, I'll come back and update you or anyone else in need with the new locations.
Wish you luck!
