Okay, my phone is LG E988, and i followed the guide: http://forum.xda-developers.com/showthread.php?t=2460859
I got until the TWRP part, managed to flash TWRP, and that is when the nightmares came out.
I used ROM Manager from the app store to get into recovery mode (With TWRP as recovery).
First try, i got into TWRP recovery page, but the touchscreen failed so i pulled out my battery and restarted the phone.
Got back to android screen, then wanted to go back recovery mode via ROM manager again.
This time, when i reboot into recovery, i got into CWM instead of TWRP. So i select "Reboot to system" to restart the phone.
Now is where all the **** starts. I'm stuck at the LG logo page with the message "boot certification verify".
Restart many times by pulling battery out but no avail. Then i went to factory reset the phone. After confirming factory reset, screen blacked out for a few sec then i went back to CWM. I cant find any backup either.
Tried all fixes from the forum but all not working. Cant extract .dz & .dll from .kdz because it cant (becomes corrupted).
Anyone can provide me with E988 Singapore .dll and .dz !!! NOW MY GOAL JUST TO MAKE IT BACK TO STOCK!!!
HELP ME FIX THIS PLEASE. MY DAD IS GONNA KILL ME !!
Note: Some might blame me for my own fault to tweak my E988, but someone said that customs for E980 can be used for E988. Please help
Edit: Still need the .dll and .dz please
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?
I was trying to install a new rom for my LG optimus G Pro F240, and after wiping in CWM recovery, I noticed that I downloaded the wrong rom, so I rebooted without thinking.
There was no way to get back into recovery, so I had to flash a new kdz using download mode and LG Flash Tool 2014, but upon flashing the new kdz, I get no network signal. I've noticed that the new version of android after flashing is 4.4.2, while the old one was 4.1.2, and also, it is now identified as a LG F240S in the android information, but previously only identified as LG F240. Upon opening the back of the phone, it says F240S/L 0227 down the bottom, F240 0025 on the bottom left, and F240S 0303 on the top right. Which model is my phone really? And where can I get a kdz that will make the network connection work again?
Edit: After attempting to flash F240S10W_00.kdz onto it, it was stuck on the SK telecom screen. Now I can't even flash the F240S20F_00.kdz file that previously worked (without network connection) because LG Flash Tool says that there is a problem with communication between cellphone and PC, this is what it looks like: puu.sh/gkpFJ/f669e8ff56 .png (Remove space)
Please help! How can I at least flash the other kdz file back onto it? I have an idea once that is done, I have my old, original rom backed up to my external sd, so if I can install any kdz that works or at least get into CWM, I can fix my phone, but even that isn't possible right now.

Model written on sticker under battery (Where your IMEI number is written) is actual model of the phone. Just remove the battery and read from sticker. All three version's lollipop Android 5 is out, here I have posted the links. Download the respective model's KDZ to get back signals:

Thanks for the help! It says on the sticker:
KCC-CMM-LGE-F240
LG-F240
09/2013
then my imei and s/n
Which model is my phone, and which version do I download for it?
Edit: And I still can't flash a kdz onto there as I still have the same problem D:
How do I flash a kdz if LG Flash Tool won't let me? Any ideas anyone?

It is not going into "Download Mode" ?? BTW such stickers with no variant name are very common for "refurbished" G Pro, I fear you got a refurb. You might have to install L, S and K one by one to see which one works.

Yes, I think I also got a refurbished, it was advertised as brand new and was a suspiciously low price, however, that's not a problem, it was working fine before I screwed up, so it is my fault.
Anyway, I managed to get it into download mode and got LG Flash Tool working, and got the lollipop that Waxim1 linked above for the F240S, the one for the F240L didn't work so I assume this phone is indeed a F240s. The only persisting problem now is the lack of network connection, how can I make it work again? I've tried rerooting, but no matter what I try, I can't root the phone now, and therefore can't install CWM in order to restore my working rom. Any ideas?

You cannot root and install CWM on lollipop yet. For that, you need to install kitkat rom, here is KDZ linke for Kit kat F240S. Install it and root and install CWM. Hit Thanks button if it helped you

I already had that kdz, but I installed it again anyway, and managed to root and install CWM and restore backup from sd card, but now even on my backup, I still get no signal? What should I do? Installing these kdz's seems to have broken my network, how can I fix this?

Did you take EFS backup with freegee?? You can restore it.
Further, go to about phone and see if your IMEI number is shown there or not.
If you do not get signal and your IMEI number is correct, just flash stock kitkat KDZ and update to next version via WIFI, you will get the network. Then you can root and install any other rom.

No I didn't back up EFS, but my IMEI is still being shown as the correct one. I tried installing kitkat kdz, but this time, instead of overwriting my stuff, it is still there, but just with new kdz, and I would keep getting android.com.phone has stopped working over and over again, and the phone would eventually just reboot itself. I've tried flashing different kdz's and still get the same result, what should I do now?

Are you flashing KDZ as "CSE" flash or Normal flash? It needs to be factory reset. Turn off the phone, press Volume up+home+power and select factory reset. OR flash KDZ as CSE instead of Normal flash. Once KDZ is installed, update it to next official version from your cell phone's menu.

I've been using CSE flash, and that is what it did. Volume up + home + power didn't work, but I got the phone to reboot into recovery via adb command, and the recovery screen just shows an android icon with a warning icon, no buttons to select. I'll try normal flash and cse flash again.
Edit: After flashing, both normal and CSE, using the default 4.4.2 kdz, it is stuck on the SK telecom screen, it constantly restarts. How can I fix this phone? Really don't want to buy a new phone, I just bought this one. Thanks in advance for any help guys!
Edit 2: NVM, I figured out how to factory hard reset it, and got the kdz for 4.4.2 working once again, but upon trying to update from the phone, it says I'm using the latest version. My signal is, as expected, still not working. My baseband and IMEI are shown as the correct ones. I also tried flashing 4.1.2 kdz for f240s and get the same result, it still doesn't even let me update from phone. Perhaps the phone was network unlocked when I received it, and flashing a new kdz locked it again. Any ideas?
Any fixes? It would be great if I didn't have to get rid of this phone
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!
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.
