ok I have a tmobile usa lg g4, I'm stock rooted but want to go back full unroot stock, I have the lg flash tool and the h81110h Kdz file, but my current ota version is h8110n with this help me to go back to stock or brick
Just as long as kdz file is intended for H811 it will be fine, final letter is software revision. (Eg: My H815 started on H815 v10a and is now on V10g)

yes it will be put back to h but once restored to stock do system updates via settings and will upgrade accordingly.

thanks man........for answering my q's....
mods please delete or close thread
well I cant seem to get this meth to work....stays at checking pc it stays at 1% for 20 min, I start oer and end up at the same point...
I cant even use twrp to simply flash a stock rom, everytime I flashed or installed anything twrp just restarts and nothing, and now when I try to even get in to twrp I end up in fastboot mode....what the **** did I do to my phone...
Follow this: http://www.androidexplained.com/lg-g4-how-to-boot-into-download-mode/ and then when in downloade mode open lg tool as admin.
Select kdz and click on Normal flash, change language and region (in your case other country and English) Lg Tool should now process kdz and reset phone back to stock.
I'll be back on here @ 3pm GMT and see how you have got on

I thought it was better to use the CSE flash if you wanted to revert to full stock. I've never tried the Normal method; only had to flash CSE once haha

To get into recovery, just use
Code:
fastboot reboot-recovery
and the phone should, uh, reboot into recovery

follow the guide attached earlier to get download mode, you do not need apps just tools that guide states. I have used kdz method on my own H815 and it worked fine.

if indeed its the chip will lg/tmobile know its been rooted
not if it is corrupted because data is lost on partitions.
Have you tried putting your phone into Download Mode and doing a full flash of the KDZ for your variant? You just need to hold Vol_Up and plug phone into computer to boot into Download Mode.

Hey Guys,
First post and i already got a problem because i messed up very much
I used to have Cyanogenmod 11 on my Optimus G, but i got several crashes and i wasnt completely fine with it so i wanted to try something new. So i updated my bootloader from CWM to TWRP and wanted to flash Artmod 5.2 Rom. I was a bit fast with my wiping, so i accidentally wiped the whole phone, so that everything was gone: Cyanogenmod, new Artmod rom i wanted to flash just everything.
I read a bit and thought it shouldnt be a problem then to just sideload the new rom, which i tried to do. I used adb sideload to put Artmod on the phone, everything was fine, flashing went through but i got stuck at the LG boot logo at the start of the phone. I waited like 30 minutes and nothing did change, so i thought something was not right.
I then just wanted to go back to cyanogenmod, tried to flash that through the adb sideload procedure but i got an error which said "error executing updater binary in zip 'tmp/sideload.zip'".
I was kinda thinking something really messed up so i tried to revert the phone to stock rom with the correct KDZ file i searched with the tool linked in the FAQ, everything downloaded but when i tried to flash the KDZ it gave me an error like this:
"12:03:59 Launching SW update
12:03:59 Unpacking KDZ
12:05:10 KDZ file extracted
12:05:11 Extract file error
12:05:13
===FINISH===="
So i searched the forums again and noticed that it should be a problem with the KDZ updater tool because the KDZ file was too big to get flashed properly. I wanted to try the LG Flash Tool 2014 then which is provided here in the forums and should work, it extracted the KDZ file, then opened the LG Mobile Support Tool to flash the file on the phone but there i start to get errors again, it either said that i am already on the correct up to date software version or that i need to disconnect the USB cable, remove the battery, insert it again, restart and try again.
I used several tools for that, i even tried it with an offline method that i found in a german forum, but every method got me the same errors, so i couldn't even go back to stock anymore.
I once tried to flash Cyanogenmod then again when i realized that the error message also told me "This Rom is for a "E975", this is a "GEE"" which i did not completely understand because it should be the total same? I edited the Updater-Script in the Zip file of the rom then and removed the part where it checks for that (1st line actually), then the rom did flash properly, phone started to boot (Cyanogenmod Boot Logo was shown) but when the boot was over i got the message:
"Type Password to Decrypt Storage" with a keyboard to enter the password. (I did never set up any password for that).
Now i am completely confused what i can do the recover my phone, either to stock or just to another rom, every method i tried did not work and i dont have any other ideas.
I can go into Fastboot, Recovery and Downloadmode, but when i tried to wipe again in Recovery it says that it cant mount my data mount point (probably because the storage is encrypted).
Somebody told me to do a hard reset with the keys "Volume down and power" which i tired several times, but everything i get is just the Google boot logo and then happens nothing or i get the Google logo, then the LG logo but after that i get stuck again, I cant seem to go into the "Hard Reset" menu which i should get into with that keys.
Anybody can help me what I could try or got a solution for this? I would be very thankful. I don't wanna loose my phone

Flash Tool 2014 works great for me every time, so try it again. Make sure you disconnect from the Internet before running it (yank out your LAN cable, or disable your WiFi), so it doesn't attempt to connect to LG servers. And don't forget to put your KDZ file in the same directory with the tool. It should go through just fine. That's by far the easiest method to revert back to stock, to get you to a clean starting point.

Umm... No, they are not the same. E975 is "geehrc", and there is no such OEM ID as "gee". There are many different OG variants. For the cross-reference between the models and OEM IDs, you can look here. Generally, you should stick to the ROMs that are designed for your model, unless you know exactly what you are doing, when trying to flash a ROM from a different platform.

Well i tried Flash Tool 2014 again and seem to get the same error that wants me to disconnects as it stops at the same position like it always did, also doesn't matter if I am connected to the internet or not, everytime it doesn't run through. This time I couldn't even read the stuff that was written in the LG Mobile Support tool because it only shows "????".
Heres a Screenshot:
The settings i made should be the right ones I think, the phone does get recognized by the computer when i plug it in because of the sound that windows makes.
I clearly dont't know what I can try anymore...
And according to the roms: well i only used roms for the E975, which is exactly my phone model, thats why i was wondering about that error message i got
Artmod is for E975, the CM11 was for E975, i even tried Mokee rom but i always got same error messages...
Nobody got another idea? I really am confused because if i can enter downloadmode and recovery there should be a way to get my phone back working.
Anybody knows where i can get maybe some older KDZ Files to go to 4.1.2 Stock rom and try to flash these?
problem

I don't know why you are seeing "???", but here is a couple of things regarding the settings, based on your screenshot:
1. Type should be CDMA (yours is 3GQCT).
2. PhoneMode should be DIAG (yours is CS_EMERGENCY).
3. I would suggest using CSE Flash for a full format (you are using Normal Flash).
Remember, this is a hacked tool, so the settings might not make perfect sense, comparing to the original ones. Just try following the instructions in the OP of the Flash Tool 2014 thread. Like I said, works every time for me...

I just tried the settings you told and used CSE Flash which worked out really well.
No i am back to 4.4.2 LG Stock rom. I think the root is gone now, but one thing i wanna ask is if my bootloader is still unlocked and custom recovery is still on it?
Anyway, thank you so so much! I appreciate your help! Thank you!

Glad to hear you are back in business. After flashing KDZ, the root is definitely gone, your BL is locked, and the recovery is stock. You will need to do all the necessary steps again: root, unlock the BL and flash custom recovery.
FIXED. Just had to try over and over until it went to 100%. Seems like its just random errors that prevent it from finishing so nothing but chance really!

I was on Lollipop 5.0.1, rooted with twrp. I wanted to return back to stock. I tried factory reset but it wouldnt work properly. Someone on xda suggested I use the TOT/KDZ method to return to stock. Both methods failed and I am stuck in DOWNLOAD mode. I tried getting back to TWRP and it goes to DOWNLOAD mode instead.
I did make a back up before this happened but I cant get back to TWRP. I used the guide here on XDA to return to stock. Please, I hope I didnt brick my G3. Im freaking out right now with no cellphone right now working.
Im desperate guys. The person/post that saves my day, I will send you a small paypal donation as a sign of thanks!

Are you sure you did the TOT/KDZ method correctly? Because if you did it should overwrite all partitions and it should go back to normal
Download the D852 KDZ from here http://lg-phone-firmware.com/firmware-Lg+G3-Tutti-41.html and then flash it with LG Flashtool. Since your having problems its best if you use CSE flash since it will wipe everything and start new

I will try the firmwares on your link posted. Thank you so much. I will try again this monday. Im stuck in the hospital with my best friend who got into a car accident. Things have been rough the last few days. If your suggestions work out paypal your wqy my friend.
I fixed it finally!
I want to ask that it hasn't any solutions yet??

Yes I flash it back those v20a bootloader, boot and modem after I got into the twrp, then I reboot it, it is stuck on the LG logo screen now...
and now I can't go back to the fastboot mode and the twrp...that 's the problem...
any idea to go back the twrp?
i'm stuck on same thing.
What I've tried.
! flashing back to stock rom using lg flash tool. Crashes at 9%. Tried flashing 20A file not allowed
both adb and fastboot methods don't work as adb doesn't detect phone and fastboot get's stuck on waiting on device
Basically the phone is stuck on boot logo after upgrading to marshmallow which all went fine and phone booted as normal after I then reinstalled the twrp recovery as before so to install supersu after boot that when the problem started. The phone can get into factory reset the two yes methods which I have tried still no luck and I can also get into download mode. basically am I waiting on a update to lg flash tool or have I ducked my phone any help would be appreciated
You probably ****ed the security flag added into marshmallow and it didn't like it one bit,that's why its better the flash newer versions of a rom when you have a recovery then an official ota ,that's where they get ya locked down .is there any devices in the device manager at all? Just checking if its hard bricked.if its labeled as q9xxxx something like that then its definitely hard bricked.like not even a jtag can get er back

No its listed as two different devices as LGE andriodnet serial port com4 and also LGE andriodnet usb modem. I have noticed that if i uninstall these two from within device manager that it then goes back to an lgmobile phone with a i on the phone icon in device manager. I have tried to find the proper driver so to make the computer see the lg phone again without error via extracting driver install exe but no joy it goes back to the above.
I wonder Is it possible to flash the .img files that are boot. system etc using lg flash tool the one with the tot methid via a script and the files I wonder. Or even convert the files needed to do a complete flash of system bootloader etc to bin files so to be read by the lg flash tool used in the tot version. or is there any other software that can convert kdz to bin.

:highfive:In the same boat, XDA's brother TheBledard Who has a same trouble in the bootloop. He said that you can use the octopus box to unbrick.
But it seem a little bit expensive....:cyclops:
Same
I had the same problem. They recently reposted the download to a fixed 2.6 so try to redownload from the genesys post. Also, flash the marshmallow kernel and supersu right after, then followed by genesys theme if you choose to use.
Retry and retry to start twrp at boot with sleep button and volume down button.... I had the same problem with marshmallow because i forgot to flash v20a bootloader, and i had finally access to twrp after a lot of times...

Hey guys, I need your help!
I tried to make my long story short, but that didn't work, so here's my complete story:
When everything was fine, I had CM13 running with TWRP 2.8.5.0.
My first intention was to restore a Stock 4.4 Backup and update it to 5.x. After restoring it didn't boot, so I did a factory reset and it worked.
Next I wanted to update to 5.0 via OTA, but that ofc couldn't work because of TWRP.
I knew the only way to update to 5.x was to flash a .kdz an lose all data. I didn't want to do that, so instead I tried to flash the official 30B image from here.
I followed the instructions given in the first post (updated TWRP to 2.8.7.0 too), but after flashing the files and hitting the "reboot system" button in TWRP it booted into TWRP again. I tried flashing again because maybe something went wrong. I even downloaded all the files again to make sure I didn't have a bad download, but no luck. So I restored the previous CM13 6.0.1 rom. At first it didn't succeed because my internal memory was full, but after deleting the 30B files it restored just fine. So when it was ready I hit the reboot button aaaannd it booted into TWRP AGAIN...
I searched the internet and found a "LG_G3_Flash2FixStuckRecovery.zip" file, but that didn't help either. (I connected my G3 to my pc using MTP in TWRP to backup all important data, so I don't care if I need to wipe everything.)
Now I knew something went badly wrong and tried using the LG flashtool 2014 for .kdz and another one for .tot files to recover my G3.
Still no luck. When using the 2014 tool and the official 30B kdz it runs till 100% at my phone (at the same time it reaches 80% on my pc at the LG mobile support tool). But then it's only showing the LG logo for some seconds, screen black, lg logo, black, ... an infinite loop.
When using the .tot method I can't get past the "Model Information Check FAIL!" message. It looks like I lost my IMEI because it shows "IMEI: NULL". I got an EFS Backup in a zip file though, so it's not completely lost. I tried both methods on 2 different pc's with win 8.1 and 7 (and win10 for some things), but I always get the same results.
When turning it on using the power button, I see the LG logo followed by a black screen and again the LG logo.
When connecting it to the charger I at first see a charging screen, not the charging animation, but the "loading" battery screen you get before the animation. But after it I get stuck in the above mentioned LG logo.
It's possible to get to the factory reset screen, but I get to the LG logo again after "performing" a factory reset. Note: On the factory reset screen, there is a blue "part" on the top of the screen which looks different compared to when using CM13 and Stock 4.4. The blue color is darker, so I guess, I partly got 30B installed.
I didn't plan to write that much, but I think it's better because I described almost everything I did.
I have no idea what to do now, I tried everything I know and could find on the internet.
So I just hope someone is able to help me getting my G3 working again.
Many thanks!
tl;dr: Only download mode left, but can't succesfully flash any stock rom.
Now... what do u want.... ????
Downgrade from mm to lollipop.... right????

I tried 21A .kdz and 10E or .tot. When using 21A kdz it gives an error. It tells me something like connect my phone again and try again. Only the 30B was kinda flashable.

You mean it's dead, completely? I thought having a download mode and seeing my G3 on my pc with a COM# port is better than seeing some QHBULK_9008 device or similar, where I need to open my G3, connect pins and some sh*t to recover it.

It is not dead, you can always fix it but it is a very weird issue

Oh ok, that sounds better. So there is hope and we just need someone who knows what to do.

Yes, I already tried the 10E tot. But the problem is that the flash tools gives an error: "Model Information Check FAIL!".

I guess so, but how do I restore my EFS without having TWRP?

OK.... Now, you flash TOT again with TOT file.... but dont change file DLL you have....
Download... file DLL fix...

Also don't forget: Maybe its because of your OS or even Setup (Hardware/Driver related). Even if it works seemingly at first glance.
That's my experience with all flashing tools that on some machines and setups there will happen some funny stuff and corrupt systems even if its reported to be working initially.
So if you didn't try yet use another PC/Laptop preferably with Windows 7 to 8.0 (only if you disabled driver signatures)
Edit: Also try different USB-Cables.

I already tried 2 PCs, one with 8.1 and another one with 7 (and 10). Both are giving almost the same result. Except the .kdz flash tool crashes on 8.1 at 99%.
I'm using the original USB cable.

Used file DLL this to restore Lollipop for my LG D855... when i flash KDZ 30B
It safe!!!!
it from user autoprime in 4rum....
I followed this tutorial: http://forum.xda-developers.com/g4/general/unlock-bootloader-install-twrp-root-t3128241
Here's what I did:
Unlocked bootloader
Booted into TWRP (version 3.0) (didn't install, just booted into)
Flashed SuperSU
Rebooted into system
Now whenever I boot the device I'm stuck in a boot loop.
So I can't boot the device up or get into fastboot mode (what should fastboot mode look like? I got into download mode at some point), not sure what to do?

I tried LGUP but it says the Model is "unknown" so when I select my phone it says "You have to select a known model, please." Can someone help?
I also tried flashing a stock kdz using LG flash tool but I got an error. Does anyone know what I can do? I can get my phone into download mode but don't know what to do on my computer.
I'll give someone $20 if they can help fix my phone for me

I had the same problem.
If you can get your phone in the download mode, than try this.
1: Install LGBridge,
2: Boot your phone in download mode & start LGBridge,
3: Than on Software Update tab, on the bottom right corner, you will see an option saying "Update Error Recovery"
4: Click on it and your phone will be flashed to latest firmware. Make sure you are connected to net as it will need to download it.
Once the update it complete, Your phone should reboot normally.
Give it a try and let me know how it goes.
