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

Don't worry, that's pretty standard scenario for the first post...

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?

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.

Hello, I've spent about the past 5 days trying to figure this out. So, how this started was, a while back when I first got the phone, I wanted 4.4, so I rooted my phone, and tried to flashify a recovery like CWM and TWRP. Both of these failed. I tried many times, and no matter what I tried, flashing always failed. But guess what, my stock recovery was erased in the process. I forgot about it until today, where I found the OTA update to 4.4 was released, and attempted to do it. To my dismay, I forgot I had no recovery mode, and instantly got the "boot certification verify" error screen. Now All I can access is download mode, to my knowledge. So I've been trying to fix this, either by installing stock recovery, or another way to install a custom. All to no avail. When I use the lg flash tool for the stock recovery, it fails at "BIN CRC Check". Every.... Single.... Time. Despite downloading multiple replacement files. I would be perfectly content with installing a customer recovery, but the ways I see require the phone to be on, and use the built in recovery mode. At this point, my phone is bricked, and I am looking for any and all ways to either A) boot back up normally without installing a recovery and fix it later, or B) install a recovery, even if it's the hard way.
Update:
I followed this thread:
http://forum.xda-developers.com/showthread.php?t=2582142
It looked like it was going to work. I am using a Xubuntu virtual machine. I was copying the files over, and every time it finished copying a file, it unmounted and remounted my phone (I don't know if that was suppose to happen, just worth mentioning if it wasn't suppose to). I was super excited to do it. Hard rebooted my phone. And now it's just a blank screen. I have no logo, no error, and no download mode like I had before. Seriously need some help here.
Update#2:
I have the flash tool correctly working. Awesome! But..... I still have no download mode here.... So I can't use the tool....
Lastly, I am aware of the title.... i don't know how that happened. I intended to type "need", but somehow that happened. I do not know how to edit it.
Can you enter recovery?

Ouch bud you are hard bricked pretty much. It sounds to me from what you explained all the partitions are wiped clean. I don't think there is any recovery from that unless you have a nand programmer

Im confused you said you had download mode then didnt? If it works try using the alternate G2 dll named 8974, because the second time I used Flashtool only the alternate dll worked which is weird because just hours earlier I had used the original, the original said wrong model/download failed the second time.

Then use LG Flash Tool, the Verizon guide works for LS980. Except use LS980 dll, and you must use Verizon USB drivers (Not T-Mobile, ATT etc), or Flash Tool wont work.

from what he said it sounds like a hard brick
Damn, not even fastboot? Feel sorry for you.
I hope someone can help me.
I bought an LG Pro E-988 which is already rooted and have a nightly CM11 installed.
I saw the LG Flex Rom and tried to install. I hit an error (Status 7), so I restored my back up. It booted correctly and decided to install/run the LG Recovery and Freegee apps as I suspected that the error (Status 7) was because I didn't install the apps before the LG Flex ROM.
After I run FreeGee, I restarted in recovery and tried to install the ROM but still same error (Status 7). So I decided to restore my back up again, but this time around, the boot is not pushing through. I'm stuck in the LG Logo.
Has anyone experienced this before and maybe you can help me to fix my phone.
I admit I got a bit excited rooting and flashing custom ROMs again after 1 year of hiatus.
Thanks in advance!!

Nothing to worry about. Here is a pinned post where you can find all the information you need.
Just download your kdz from here and follow the steps from this post
Download kdz, install lg flashtool, lg drivers, after turning off your phone, press volume up and down together and connect your usb cable to get into download mode, then follow those pictures in that post to flash the kdz. You will be back to stock.

Thanks a lot man :good:! Although, I'm stuck with 'Connection error' in the FlashTool. Is this normal? I tried again and again more than 20 times but I'm getting the same connection error.
Also, earlier I was still able to go to recovery, but now even if I press the power button it goes straight to the download mode.
Hope you can help again.
You cant get out of download mode? did you try volume down and power button together for 5 secs? And btw what error are u getting on flash tool? its not detecting your phone? Did you install the mobile drivers?

The error was in the LG Mobile Support Tool (sorry to in the Flash tool). During the upgrading of the phone it always give the error - 'Connection to server failed. Try again in a moment'
Also, if I try to turn on the phone it will not boot but go straight to download mode.

Did you remove the battery and put it back in? And it still goes to download mode? Try starting the phone pressing Volumedown+power key for sometime or you could try Volumeup+Homekey+Power to boot into recovery and try restoring backup or flashing some other rom and see if you can get out of boot. I really don't know why you are getting that connection problem. I got stuck at boot a couple of times and followed exactly what was given in that post and reverted back to stock. I guess some of the senior members will help you here. Meanwhile ill see if i can search a solution for that connection error, i haven't faced that yet so i really don't know the fix. There is a second TOT method given in that post, that might help.

Yup, i tried removing the battery. Also tried different key combos to boot but it all goes to the download mode, with the small with box in the middle.
I also tried the option of going straight to the LG mobile support tool (not the LG Flash tool). But the same server connectiom error.
Thanks again for the help.
Hope other members can help me too.
Since I'm not able to do recovery using the KDZ file. Can I use the TOT file?
I have E988 Singapore version, but the last ROM installed was with a CM11. And in the Phone details it shows E980.
Will it work or will it just make things worst?

Yeah, I read that also. I used a windows 8 pc previously, that might be causong the connection error. I will try my old pc and hopefully it will work.

So I have an LG G Pro F240l
So essentially, because I flashed the wrong recovery (the F240k, as that's what I thought the phone was), this means I have no recovery.
I cannot root my phone, because basically the recovery doesn't exist.
I can use adb.
I can't do anything after booting other than use ADB, because "LG IMS has stopped working" will constantly appear and impede my ability to achieve anything (this occured after flashing the new lolipop update, which while it technically worked, I should have done a factory reset before doing it.
KDZ files are only the roms, I can flash those fine.
I have a 4.4 rom, and the new lolipop build in terms of those files.
I am unable to locate the tot or dll files I need for my F240l
First, removing LG IMS would make life easier, as that should theoretically fix the problem, making the OS at least useable.
Secondly, how would I go about getting myself a recovery that works (even the stock recover), and flashing it without already having a recovery?
Is there a way I can temporarily root the phone without going into recovery at all?
Please help, I'd rather not have a $160 paperweight..
Edit: I've gotten the ROM working, but I still have no way to root or install a recovery.

Make sure you have LG Suite installed and of course all the drivers. Put the phone into download mode and engage Repair Upgrade Errors in LG Suite. You should get back to stock.

I just did this, all it did was re-flashed the same rom I already had (presumeably the .kdz) file. The recovery is still missing and only showing a an android with a compartment open and a red exclamation point.

This is a wild shot in the dark, but try holding vol down, home, power.. then wait for prompt and confirm hard reset with power button. then try the lg suite "repair upgrade" again while in download mode. Hope you can sort it out.
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 can help you... by teamview. Ok

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.
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.
Many thanks!
tl;dr: Only download mode left, but can't succesfully flash any stock rom.

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.

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...
https://drive.google.com/file/d/0B0VrTZddvLF7b3Q1b1BlQ2w0clE/view?usp=sharing
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.

Hello to all of you,
Thanks in advance for any help you can provide.
I bought second hand a LG G4 H815 with CyanogenMod 14 already installed on it.
Everything was fine until I installed my Ebanking apps, that would not function with an unlocked bootloader. I needed to return to a clean factory safe state...
It was the second time I flashed a rom in my whole life, the first one was a Galaxy S plus years ago.
I followed all the instructions for the KDZ flash in this tutorial but I stumbled upon a "Upgrade stopped due to error" in LG flash tool.
I retried 3 or 4 times but with no luck. I verified that the ROM was correct for my model and it was. European and all...
I tried LGUP but my phone is unknown ( at least it's detected)...
I read some posts and told myself "I probably have messed up something, let's try it again with a fresh thing"... I clicked on the factory reset button and carried on.
There the phone booted on TWRP (That i didn't know existed before this). As I explored the menus with a TWRP google search on the computer, I began to realize that the factory reset was maybe a bad thing to do with a custom rom. I tried to reboot but I always end up booting on TWRP.
I re-tried to flash in download mode, but with always the "Upgrade stopped due to error".
I also tried to flash directly from TWRP a stock rom. Didn't work.
I was beginning to lose it and tried to flash the CM14 version I had before, juste to have a working phone again, but even this didn't work... I'm stuck with a TWRP phone
I need some help there...

uninstall any drive for g4 from pc and reinstall again and lgup. now reboot phone to download mode when lgup is open first check upgrade opsion and when open kdz check refurbish opsion and start. good luck
Thank you for your answer
Still no luck
Uninstalled drivers
Rebooted PC
Reinstalled the drivers
Still unknown device
The best way to flash stock image is to use official LG Bridge app. Download it, turn off your phone, connect it to PC while holding volume up button - phone will go into download mode. Then there is option for software restore in LG Bridge but i won't tell u where exactly. If it won't work i would try on another PC. If it won't work maybe you would be able to flash stock image trough send_command but i won't help you with it.
