[Q] LG Optimus G Soft-Bricked? Please help me to recover my phone

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?

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 don't know why i see "???" also, but it didn't matter
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.

[Q] LG G Pro F240L, no recovery at all, and no root to flash one with

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.

[solved] D855 Softbrick - need help - DL mode working but no succesful flash

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????

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.

You are flashing the wrong recovery for your model. It seems your phone is refurbished with a different board. So make sure your model and then flash recovery.Or try d850 recovery. Because most refurbished have d850 board.

That's the problem try to understand. Refurbished are meddled with everything. If you want to make sure the model number. Open your phone. Your model will be written or board.

Refurbished phones have changed or tempered IMEI numbers. IMEI would say d855 but board inside phone is mostly changed.

Second Phone Bootloop - How Do I Flash My Phone?

Hi,
I have the Verizon LG G4 model. My initial G4 was replaced by LG a few months ago and now this phone is bootlooping as well.
I have tried the Safe Mode, the Factory Reset option in the recovery menu but nothing works. I somehow managed to *ONLY ONCE* normally boot into the phone but it went to bootlooping after a few seconds of normal operation.
I *MUST* wipe the device clean before I send it to LG so I thought I'll try flashing the firmware.
I saw many guides but if someone can direct me to the one specifically for the Verizon model, that would be awesome! Also there seems to be a lot of tutorials but I don't know which ones the most recent.
Also, I went to the download mode and it says 633A B71 modified on the bottom. Is there a specific firmware file I should be downloading? I am downloading the VS98611A_06.kdz from

dont flash it yet.. first make sure what antirollback you are on.. ihave no idea about verizon.. if antirollback is higher youll brick phone...
the oldest firmware must be lollipop and maybe the second one too or marsh mallow.. dont flash it untill you know about antirollback and what version to flash.. or you may brick your pghone ask in the verizon thread.

SO I checked the last update from Verizon was the VS98626A version. So I downloaded VS98626A_00_0615_ARB02.kdz and started the flashing process via LGUP. Everything went smoothly, the phone showed progress and said the firmware was being flashed until it had to reboot the phone. When it reboots, the phone still goes back into boot loop mode.
Any ideas on how to fix this??

Then you have the bootloop hardware problem. you need to send it back for repair to verizon or LG USA..
