About flashing TWRP on the LG G2
This is a reply to the last post in the LG/TWRP post: http://forum.xda-developers.com/showthread.php?t=2449670&page=116
And specifically, I was about to ask the same question as "ctowne", about the lack of loki_flash in the loki package pointed in the instruction page.
I'm really stuck here, because I already "soft bricked" my phone (rooted LG G2 D802 international) in two different states that required a complete flash and wipe with the originale LG ROM and tool. And one of these was caused by the AutoRec tool, which apparently doesn't work for lot of people and could lead to bootloops.
So, before trying anything I'd like to be sure I'm doing the right thing, and more importantly, that I have the complete instructions to do it.
To sum it up:
-according to the thread, I need the loki package and the TWRP package, but there is no loki_flash inside the actual loki package
-but there's one inside the last TWRP package! Should I use this one?
-also, is not clear where I need to move all the files to make everything works
Thanks in advance.

Are you sure you downloaded the correct version of autorec? I have a VS980 and autorec worked perfectly....even after updating to the latest version (26A), after which I flash TWRP 2.8.0.1 via recovery (which autorec installs 2.7.0.0).

Apparently something went wrong with my first install. I tried again and the AutoRec flash went OK!
BTW, how do you update TWRP? Just flashing the zip via recovery and nothing else?

Yes. Have whatever version of TWRP on your phone and flash it. Make sure to reboot recovery and it will show the current version flashed.

[Q] Lg G2 lollipop root problems! Lg root zip not working!

I recently updated to lollipop! My phone is lg g2 d800. I previously had rooted with twrp on Kk. I used lg flash tool to flash back stock. I got it updated to lollipop ota. I have tried lg root zip. I do everything exact. Everything works until I put phone in download mode. I do the send command to choose correct port and type commands to execute. Nothing happens I just get a flashing cursor. I have Also tried lg one click root script it also freezes at firmware update. Any help would be appreciated. I have searched the forums these Methods seem to work for everyone else. I don't know what the problem is.

LG G2 F320 (soft?) brick (no recovery, no fastboot, rooted, can't flash KDZ)

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

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

D800 - I just can't get CloudyG2 working no matter what I do...

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?

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?

LG v20 H918 Stock recovery+rom?

So I just recently wiped all the data on my phone in a rush except TWRP and I want to revert back to stock ROM. But LGUP doesn't recognize my phone when I do use TWRP or fastboot mode. From my research done I need to get stock firmware update back in order to get LG UP to work again? I'm not entirely sure what I'm doing since I'm new to this. Help im noob. no backups too.
I tried this thread:
https://forum.xda-developers.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903
But... LGUP doesn't see my device as said and KDZ files don't flash on TWRP. I tried doing some random .ZIP files of stock roms which I'm not entirely sure I did correctly.

You dont use TWRP or fastboot with LGUP you use Download mode

Yes I know that. But TWRP replaced my download mode because whenever I plug in my device and press the UP volume key TWRP showed up instead.
Anyway I fixed it myself so thread close pls. Not sure how to do this.

Whenever you fix your own problems, it's still considered good forum etiquette (to many people including myself) to still offer the solution you came up with so that anyone else reading the thread because they might be having the same issue that you're having would love to get a working solution too.
Anyway, the issue is that the lafsploit method using the USB Linux distro overwrites the laf partition to get TWRP installed on the device. Most people never bother to fix that problem but the solution is to flash the laf_restore.zip file (I got it from another thread but can't find that thread at this moment so I'm just going to host the file on Drive for safekeeping):

After you flash TWRP temporarily on the H918, then update TWRP (flashing the newest version), reboot back into recovery/TWRP and then flash the laf_restore.zip which will restore the laf partition(s) to their proper state - AFTER all this then you should be able to get to Download Mode again normally if you must.

Oh yeah I was sorta thinking about posting my solution last night. Anyway the solution I found was to find a .ZIP file of an older stock ROM like the H91810u using what I used which was TWRP since I didn't know what else to flash it with.
I found the file on this thread IIRC. A lot of the links are dead but the 10u version wasn't for me.

My main concern was to just get stock ROM back. I only wanted stock recovery because that was the only way I knew to flash .KDZ files using LGUP. Although I guess bootloader is still unlocked on my phone. But stock download mode still comes back.
I didn't do anything after that but it seems good enough for me now since I don't turn turn off and on my phone a lot. Till another day.
