Hi all. I'm not a novice when it comes to rooting and flashing but I'm stuck on this one. A friend of mine tried to install CM11 on this phone, the LS980 and somehow really jacked it up. It's stuck in a bootloop, but I can get into download mode and stock recovery. All data has been wiped. I have tried using the LGFlash tool to install the stock tot and dll but it fails. It fails because the the tool says the file is the wrong model for the phone. Here's the thing, its not. But somehow the phone now thinks its a D802 instead of an LS980. (This happened during the CM11 attempt somehow) The flash tool fails every time. I even tried the D802 files and it started to flash but failed about a 1/4 of the way through. That confirms that the phone definitely thinks its a D802, weird. When I hook it up to the LG Support tool, it tells me the phone is a testmodel!
Needless to day I've tried everything I know how. ADB sideloads, different recoveries, and I've researched for hours on end. I have hope that there's still a solution. I would be golden if I could get a recovery on it, either TWRP or CWM. Any help is appreciated.
have the same problem. simply cant recover the recovery.
My recovery for e988 g pro in lg g2. I try everything for fix the recovery but cant help it. Is there any way to re build recovery?
my ls980 thinks it is the d800 and I can't seem to flash it back to the ls980.
I flashed a custom ROM thru twrp and I got an error. I tried restoring the backup and the system partition would not mount. after poking around for quite some time I tried restoring the phone in download mode. apparently the computer thought it was the d800 and flashed the system for that phone. when it restarted I saw the at&t boot screen and when it started up it was not working correctly.
I put it back in download mode and tried flashing the phone again. the computer was sure it was the d800. then I tried flashing manually using the DLL intended to convert this and the tot file for the ls980. I get the error saying I can't convert from the d800 to the ls980.
I then tried flashing thru adb from both windows and linux. both say they cannot find the phone regardless how I try connecting.
since I flashed the factory files the phone will not start in recovery mode I have no clue why.
so now I have a phone that:
will not flash the ls980 tot file,
will not connect to adb,
and will not boot into recovery.
now what?
Im sorry I know this should be going under the ls980 development section but since I made a new account a year ago I haven't been on here that much to have the permissions so deal with me.

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.
Hi
I tried the one-click root method on my d855 32GB running stock 5.0 but now it doesn't get past the LG logo screen (said successful). I can get into fastboot but get a device error when trying to run LGFlashtool.
Strange because it started flashing in LGFlashtool but stupid Paralells VM (I'm running Mac) installed some kind of tool and autorebooted in the middle of the flash! Can still get to fastboot but get device error.
Any advice on if I can get this up and running?
You may have to flash stock firmware here.
Thanks. I can't get it to flash using Win 7 VM. I'll try tonight on a dedicated PC and see how I go. Got the KZ file but seems my IMEI etc is all corrupt (still got it on sticker under the battery) when I go to read phone info through LG Flash tool....
Had the phone for two days
Fixed! Had to use another computer rather than VM on a Mac. Also had to try it a few times. Actually flashed the kmz then had to flash the tot method. Least that was the combo that worked. So relieved.
I have rooted all my phones.
I was following a tutorial to root my LG and instead of flashing TWRP I was advised to boot TWRP which I did (fastboot boot recovery.img)
Using TWRP in that mode I flased supersu.zip, then phone went into a loop.
Not sure where I ended up
When I enter "adb devices" it shows my G4 as offline.
How can I move from this point please ?
Hi guys?
Any ideas ? Please.

if you can enter download mode vol up connect usb then download corresponding KDZ file and flash with LGUP using the refurbihsed option. good luck
adb offline means you have to accept the popup on the phone when connecting to the phone from that pc. If your screen is not accesible then you have to flash the kdz as mentioned above.
Next time, when you enable the USB debug, also connect to the pc and answer that popup. and you should be good.
Thanks guys
Are you sure I would be able to flash KDZ ?
I flashed supersu.zip without TWRP installed and now when I turn on my phone, LG logo shows up but boot process isn't progressing.
Probably too early for PC to detect mobile and I suspect thtats why it shows offline in adb...
I'm very cautious about guide/how-to I follow now. If you have any links on flashing KDZ that you could share I would appreciate.
Also - what will flashing KDZ do exactly ? Flash new system directly to /system partition ? (just trying understand)
If using LG UP you can choose Upgrade that will only write the system, or choose Refurbish, this will erase /data so you will end up fresh. It depends on what you want.
I am sorry for late reply. Very busy week, and needed to sleep a bit...
Fortunately LGUP is working. I have Uk version of my G4 (exactly H815 unbranded. No more info under battery).
- How can I be sure I am getting correct KZD file?
I'm downloading H81520D_00_0115.kdz but never used those and I don't want to flash wrong one...
I have found also H81520h_00_-516.kdz.
Don't want to be a pest but... if it's a matter of quick google search for you - could you be so kind and drop correct link for me ?
I cannot check anything with phone in this state

V20h is newer so you should flash that. If you go to general threads section you will see that there is v20l that is even newer than v20h, and is from UK. Happy flashing
Edit: here you go with the link to the new firmware thread http://forum.xda-developers.com/showthread.php?t=3480887
OK, I'm not sure what is the problem here but thanks to your advise I restored system. Everything was working fine. Then I installed TWRP. Then using TWRP I flashed UPDATE-SuperSU-v2.46.zip and then... phone wen to the same loop as it was before.
Could it be some incompatibility of supersu ? Or perhaps I need some kernel or other items. Or perhaps other root manager ?
Ok, found the problem. On Marshmallow flashing supersu will not work - I flashed pre-rooted kernel and works like a charm. Just a shame I had to spend half of my sunday flashing, erasing, backing up, restoring, etc.
Thanks for your help guys!
