Hi all,
Let me try to walk you through everything that I've done to try and get some help here.
I have an lg g2 sprint (lg-ls980)
1. When I got it I first upgraded to android 4.4.2
2. Then I rooted using stump root
3. I installed xposed and a few xposed modules....I then decided Id rather have a different rom, so
4. I used autorec (which to my understanding changed my kernel in order to workaround boot loader and install twrp? is that accurate?)
5. Booted to twrp, wiped data and installed cyanogenmod and gapps
After this I get stuck and can't boot past the lg logo, so I booted back to recovery and restored my backup. So I did the same and tried pacrom this time with the same results.
I then decided that if I'm going to be stuck with stock rom I at least want my knock on back, so I flashed the patched kernel and same thing- stuck at lg logo....
I know I downloaded the correct zip files and placed them on the root, and always wiped before flashing.
Then I went into download mode on the lg support tool to try to get back to factory, but it says my firmware and recovery is up to date. The odd thing is that the lg support tool shows my phone as ls740 rather than ls980... is this because of something that autorec changed? Do I need to download zip files for ls740 instead? So confused..
About phone in my g2s settings shows android version 4.4.2 and kernel version 3.4.0
Anyways, if anyone could help me to successfully get one of these roms to flash and get back to the kernel that supports the knock code I would really appreciate it.
Thanks in advance!
Hi Folks,
My apologies if this has been covered before. I was unable to use the forum search and after 3 hours of reading and tinkering, I haven't gotten very far.
I have a fair bit of flashing experience with multiple devices and was under the impression that the Tmo G2 is very easy to flash.
I have a new Tmo D801. The version on the phone when received was 4.4.2. After much scouring of XDA, I found I needed to go back to 4.2.2 to root, flash TWRP and put a new custom ROM down. After more scouring, I managed to use the TOT method of downgrading the Android software to 4.2.2 and that was successful. I used IORoot to root the device, but per many instructions, I never saw the recovery menu. I have tried multiple ways to boot in to recovery. When doing a command line "adb reboot recovery", the little android with the blue wire frame shows up briefly and then the phone goes to the LG icon, then in to the stock 4.2.2 firmware.
What am I doing wrong? I've read through a number of threads including the following:

I haven't taken the OTA that keeps coming up on the phone.
Any help is greatly appreciated.
I got this figured out.
I downloaded an older version of TWRP and installed via Flashify in the OS. Once that was installed, I upgraded TWRP to 2.8 and went through the whole process of upgrading to kitkat, re-rooting, installing AutoRec to get TWRP back on, upgrading TWRP and installing a new CloudyG2 ROM. Everything seems to be working great.
This thread was incredibly helpful:

I tried updating the bootstack on my LG G2 since it was having WiFi disconnect issues. After updating it with the Lollipop bootstack on a Lollipop ROM (Dirty Unicorns 5.1.1) I couldn't use the camera and flash light.
I then decided to just flash the stock LG G2 Lollipop KDZ and start afresh.
However, my phone became bricked into fastboot mode but I got out of it by flashing all the img files through fastboot. Now it is getting stuck at the LG logo and I can't enter fastboot or recovery now... I can access download mode but it says it's still rooted and when I go to flash a new KDZ (tried multiple versions) it says phone disconnected, or force closes the support tool.
I've been in this situation before but I can't remember how I got out of it...
I'm running Windows 8.1 and have read that you can't flash KDZ through the support tool on Windows 8/8.1 so I'm in the process of installing a Windows 7 virtual machine.

Oh my god.. What happend to you g2 ?
First, don't give up, sooner or later you are gonna unbrick your G2 in the end. I have been there too.
If you can get into download mode, you are very lucky.
Just Ignore root thing, it has nothing to do with flashing KDZ/TOT.
You got to learn how to use LG flashtool first.
http://forum.xda-developers.com/showthread.php?t=2432476
My suggestion is that just stick to TOT tool instead of KDZ tool. Sometimes KDZ tool fails during flashing without proper reason.
And that problem often happens when you are going back to stock rom from CM12.1 roms like DU, BlissPop...
But one thing to remember, TOT tool would wipe out your internal memory.
Unplugging you external SD memory is recommended while doing KDZ/TOT flashing.
If you still fail with TOT tool.... It's no good. You may have to try short-circuit method.
Good luck.

Failed everything except TOT. The TOT took about 6-8 hours to download...
Flashed TOT and it booted fine, then updated to stock Lollipop with KDZ. It's currently working EXCEPT....
Camera doesn't work still, can't send a text because the "Messaging" app force closes, don't have the flash light, and I can't seem to start ABD to root it.
SD Card is working fine though. Using a 64GB formatted to FAT32 and restored all my pictures, music, etc.
The main thing is the camera and messaging app, plus the flash light is really handy when working on my car.
At least I have a working phone
Managed to get it recognised in device manager and ADB but when rooting it stops at 45%...

Oh... I think there's possibility your camera hardware has gone out of order.
When you are in LG stock rom, and still experience problem... well I guess it's not software problem.
Because TOT flashing is complete software factory reset. It revert everything to out of factory state.
And for rooting, sometimes it just get stuck. but suddenly it just get rooted. I can't explain the reason.
But you should remember one thing in mind, don't initialize V3. It's anti virus program, and it blocks rooting.
When you boot for the first time, you maybe was asked if you agree with V3 software, just choose don't agree and skip it.
If you still fail rooting, just flash KDZ/TOT again to go back to KitKat. When you're done with flashing KDZ/TOT, just stay there and don't update KK version because KK update could block rooting.
Of course you should not agree with V3 software install.
Use towel root, it's the most easiest way. go to towelroot.com and download apk. (click logo)
Root your G2 and use KitKat version of autorec to install TWRP.

Got root eventually. Not sure why but it worked after like the 6th time...
Is it the bootstack or something that's causing the camera and flash to stop working?
It only started having those issues when I installed the new bootstack.
I'm about to throw this stupid phone against the wall...
I cleared Cache and Dalvik Cache after successfully installing TWRP and it came up with "Security Error" and I can't boot

I can guarantee TOT flashing would revert everything to factory default state. So Even if bootstack has caused problem, after flashing TOT, everything should be back to normal. Because TOT flashing includes bootstack.
Tot flashing completely wipe out your G2 and rewrite EVERYTHING.
I am 100 percent sure that camera's malfunction has nothing to do with bootstack.
BTW, which version of autorec did you use ? There are two versions of autorec. You should not be mistaken.
Because KitKat autorec would destroy Lollipop's kernel and cause security error.
To my knowledge, XDA forum has only KK version which made by cloudyfa.
Even if you had security error, It's too early to give up.
First, Power off, and holding vol.up and connect USB. If you are lucky again, you would see download mode.
Or try to get into recovery by pressing vol.up and power.
At worst case, you can't get into recovery nor download mode, either.
But That doesn't mean you should throw out g2. You can still revive G2.
Recently I made how to revive bricked G2 (only F320 specific) in Korean. It's already known method.
You have to open back cover and disassemble to try short-circuit.
If you really want to try short-circuit method, I would make short translated version for you.
G2 is really hard to brick. So don't throw up until G2 is real dead.
Good luck

I probably installed the wrong AutoRec then...
Flashed the KDZ again and booted but it's saying "System UI has stopped", com.android.phone has stopped", etc.
I guess I have to TOT flash again and start over... again...

In normal case, after flashing TOT, there should not be any problem at all. Because It's in factory default condition. I mean, it's like the first time you open up the package right after you buy.
As for your case, I think something is seriously wrong.
Make sure you flashed right TOT matched to your F320. As you already know, there are 3 variants, F320S, F320K, F320L.
Ah.. I almost forgot. If you want to try aosp roms other than LG stock rom, you can try when you are in KitKat, too. While you are in KK, don't update KK version. Because updated KK version blocks rooting.
Right after flashing KK tot/kdz, try towel root. It's the easiest rooting tool.
You can download it at towelroot.com
After rooting, install supersu and use KK autorec (which made by cloudyfa) to install TWRP.
But In my opinion you should figure out why stock rom has system UI crash.
In authorized LG service center, engineer uses the same TOT tool. In theory you can't have any problem after flashing TOT. unless there are some damaged hardware.
This is all I can help. Hope you solve the problem.

TOT is for my F320S, just flashed it again and it worked.
Installed AutoRec LP and it worked. Ended up installing Dirty Unicorns 5.1.1 which worked.
Camera and flash still don't work.
I remember this happened to me ages ago but I can't remember how I fixed it

if anyone can help me. I dont know if it'is a hard brick or not, but i can go to the fastboot mode only. when i try to erase some partitions tho i get this error FAILED (remote: failed to erase partition) and my phone says Failure sending erase group start command to the card(RD;2).
I've tried to flash files too but nothing seems to work since everything leads me to an error and the phone says this when i try to flash it :Failure sending write group start command to the card(RD;2).
if anyone is able to help me, i would very much appriciate
I've been having issues with my phone, and I'm not sure if this is a HW issue or not, but no matter what I do, either I lose recovery or get a security error. I poked around and found some instructions in the CloudyG3 thread. They're for 3.0 but I would guess 3.3 wouldn't be different enough to brick this thing. Can't remember who the quote is from, I just copy/pasted it, but here it is:
Some of you sent me a PM asking for the install instructions on D800 and this is how you install CloudyG2 3.0:
Downloads:
1. Download CloudyG2 3.0 - https://www.androidfilehost.com/?fid=95897840722646001
2. Download Patch - https://mega.co.nz/#!sVY0mRTb!qn7S9B...3m_QpMQkgzunn0
3. Download Signal Patch - https://dl.dropboxusercontent.com/u/...l_Variants.zip
4. Download LP Baseband - http://blastagator.ddns.net/modem.php - d800-30f-modem-blastagator-signed.zip
5. Download KK Bootstack - http://blastagator.ddns.net/bootloader.php - bootstack-d800-KK_20c-blastagator-signed.zip
6. Optional: Download JB Bootstack in case if you want to revert the installation process and go back to your current ROM - http://blastagator.ddns.net/bootloader.php - bootstack-d800-JB_10d-blastagator-signed.zip
Flashing Process:
1. Backup the existing ROM (including EFS, Modem, etc.) in TWRP - very important and copy it over to the computer, just in case!
2. Wipe System + Data + Cache + Dalvik Cache - Do NOT select internal storage as it contains all your downloaded files + backups!
3. Flash KK Bootstack (downloaded from Step 5)
4. Flash LP Baseband (downloaded from Step 4)
5. Flash CloudyG2 3.0 (downloaded from Step 1) - Leave the default in Aroma when you have to pick the variant. Do NOT reboot the device as the patch installation (next Step) is very important.
6. Flash Patch (dowloaded from Step 2) - Select your variant.
7. Flash Signal Patch (downloaded from Step 3)
8. Reboot
Enjoy!

I'm guessing I have the incorrect files, most of the links I found in the thread with these instructions didn't seem to work so I Googled for them, maybe I don't even have the correct files. I took a screenshot in cmd of the exact filesizes.
Any help would be greatly appriciated!

Coming off a fresh TOT flash, I root with towelroot, flash TWRP using AutoRec, flash bootloader, then flashed Cloudy. It will boot at first, but then I run into "black screen of death" or security errors or when trying to boot to recovery, I'll run into similar issues. Does Blastagator's TWRP make the difference here?

I had the exact problem happen to me ....... I got the black screen of death .... phone wouldnt boot ....... and when i used the kk bootloader i would lose recovery ..... I was coming from kk to CloudyG2 ....
This is how i solved.
1. Flashed back to stock, stumproot to root Autorec v1 for bootloader
2. used Flashify to upgrade to 2.8.7.1 ( its now 2.8.7.3)
3. Downloaded n used bumpted LP bootstack and flashed blastagator stripped rom (its in flashable zip and installs everythin including modem .... patches etc EVERYTHING) http://forum.xda-developers.com/att-g2/development/rom-stock-lollipop-30b-stripped-t3144195
4. Downloaded kk bootstack , CloudyG2 3.3 and clean flashed in recovery
I have been enjoying Cloudy ever since ...... D800
Thanks all, got it running! Cloudyfa has done some absolutely brilliant work here with this ROM, as well as xdabbeb with the advanced camera driver and xCam. I'm usually a vanilla-or-nothing guy with my Android ROMs but this one is quick and power efficient. The KitKat ROM that shipped with the phone was super bloated and gross, but I'll admit LG UX 4.0 isn't really that offensive, plus I like the goodies like Multi-Window and QuickRemote. Once I disabled/hid some of the remaining LG bloat, it's surprisingly pleasant and not really that far from AOSP aesthetically. Again, cheers to those who provided the assist on this one for me!
... now my only question is, should I try CloudyG3?
