When you flash back to stock, everything is like you bought it at the store. Locked (or non-rooted) .
[LG Optimus G Pro] jkusmc:
Thanks, one more question I saw that was asked in an earlier post. Everything went fine, but now the phone won't register on the network. I cannot manually input apns since it won't save them. Any suggestions?
[LG Optimus G Pro] jkusmc:
Disregard. Somehow the SIM got fried during the flash and had to be replaced.

I think this will work for me but I can't download zip file to extract TOT file successfully. Eve time I download and extract for get error message file is corrupt. Downloaded about 10 times every time same message.

Anyone have TOT file for F240L would be really helpful.
[LG Optimus G Pro] Jasbo:
WELL I THINK THIS HAPPENED TO ME!

I had TWRP installed, and since installed CM10.1, after testing for a while I decided to go back to stock but found out TWRP couldn't read its own backup because the card isn't formatted FAT32! how absurd is that. So I tried to remove TWRP with Freegee using the backup Freegee made but all that did was get rid of TWRP for CWM.

Now I can get into CWM, but not Download mode!

So for now I have:

CM10.1 (works fine)

CWM Recovery (can boot into)

Download mode doesnt work anymore (just boots CM10.1 when I plug in the power cord)

How can I get back to stock now? any help would be appreciated.

[LG Optimus G Pro] mimi904:
I downloaded everything and slowly did it step by step, i was almost there but im stuck where i couldnt find the dll file. Please help mee :(
[LG Optimus G Pro] mauro8888:
You have the TOT file?????????????? For the e988!! Help meeeee :(
[LG Optimus G Pro] KarimSalloum:
Hello,

do you have the files for the E988?
[LG Optimus G Pro] mauro8888:
We can't find the TOT of e988 :(
[LG Optimus G Pro] mimi904:
Yeah i believe i have downloaded that as well, but when i was getting ready to flash it i couldnt locate the dll file

---------- Post added at 08:48 PM ---------- Previous post was at 08:37 PM ----------

So downloaded it again and opened the LG flashtool V1.5.10, now at the model config window i selected the manual mode and "still" unable to find that file. The s/w is no prob. I know im missing something

---------- Post added at 09:31 PM ---------- Previous post was at 08:48 PM ----------

I just realize my lg is E980 not E988. Would it matter? If i flashed it with e988? If yes Where can i get a e988 tot file?
[LG Optimus G Pro] mauro8888:
You have the TOT or the KZ file???
[LG Optimus G Pro] mimi904:
Yes i have both the tot file for e980 and the dll file. The e980 dll is not recognize by the LG Flashtool. It only recognizes the e988 dll file. It might work if i can find the e988 tot file so i have both. But the question is, is the E988 firmware works for E980 phone. Thanks again mauro!
[LG Optimus G Pro] mauro8888:
You are flash the e980 firmware and the 988 ddl with lg flash tool??? is working??
[LG Optimus G Pro] mimi904:
No it didnt work. I just cant fnd a E988 tot file thats my only hope.
[LG Optimus G Pro] mauro8888:
I want create but all tool for create the bin file dont exctract the kdz!!!!!! :(
[LG Optimus G Pro] nelsonator1982:
Drivers initialization

1. Put the phone into download mode. (Turn off device, keep pressing volume down while plugging in the micro usb cable. If this doesn't work, try holding both volume keys instead)

2. Let the phone initialize and install the drivers. Once done, in Device manager, you should see the LG phone listed under COM ports (something along these lines).

3. Find that LG entry in Device Manager, click on Properties, Advanced and then change the COM port to COM41 and close/save.

4. Unplug your phone! Important step.

im on a windows 8 laptop and cant find the lg in device manager or com ports????
[LG Optimus G Pro] cwis:
How do I get to recovery if the phone doesn't allow me to get past the att boot screen? In the very beginning of boot up it has an error message

secure boot loader

Cause device unlock, so boot success

Anyway to fix this?
[LG Optimus G Pro] 1Zero3forlife:
Hold volume up, power, and home button down, once the LG logo shows up let go of the home button only.
[LG Optimus G Pro] nelsonator1982:
no windows 8 fix its all i have
[LG Optimus G Pro] mimi904:
Im a newbie, i tried and download and followed step by step slowly. Im almost there but on the lg flash tools it keep saying "wrong dll file" im missing something here but what? im using win7 my og pro is E980 but when i bought it, it was rooted and its e988 instead. Please show me the way "masters" thNks in advance!
[LG Optimus G Pro] Jammol:
What's the name of the DLL file? Make sure it says e980 in it.
[LG Optimus G Pro] mimi904:
Yea the dll file is E980 but couldnt find it. Btw the E980 comes only in "rar" file. Igflashtool only recognizes the E988 dll file, i looked for E988 tot file and couldnt find it online.
[LG Optimus G Pro] 1Zero3forlife:
If you read the instructions, you have to extract both files...then you will have your dll.
[LG Optimus G Pro] mimi904:
I shall try that again i hope i get it this time
[LG Optimus G Pro] mimi904:
I did download it again, and when i go to my download, its there but it cant be extracted it turns into this.... LGE980-20130314_LGFLASHv151.rar
[LG Optimus G Pro] mimi904:
Man how did you locate the dll file From lgflashtool? Im assuming it worked for you. When i extracted it. It wasnt dll file but .rar instead.

---------- Post added at 01:23 AM ---------- Previous post was at 01:04 AM ----------

Where or how did you locate the E980 dll file using the lgflashtool?
[LG Optimus G Pro] jdk2:
Extract the .rar for the .dll. Same as a zip file. Zip file has the rar file which has the dll file inside. Convoluted but true.
[LG Optimus G Pro] mauro8888:
Why i have the error failure previous load when i click the yellow arrow?? :eek:
[LG Optimus G Pro] OsamaBT:
Thanks man !

I had already followed this guide as I was not getting any network on my optimus g pro F240s & I was successful in first try,

but the problem still remains !

I have noticed that I get an unknown IMEI in system settings when sim is inserted, if not then it displays IMEI !

What should I do ?
[LG Optimus G Pro] mimi904:
I had everything, the only thing i dont have was that "win.rar" application. Thanks madmack!! I was able to flash it no problem! FYI to some of you guys that arent able to find the "DLL" file, win.rar might be the answer. Thanks to all again!

Brick

Hello everyone, after trying to recover by this method was of brick e988. He did not respond to any action. In Device Manager defines as "qualcomm hs-usb qdloader 9008." Please help and sorry for my bad English.
[LG Optimus G Pro] hyelton:
Well that would be cause you flashed the WRONG stock rom to your phone... This guide is for the AT&T Version Only! You most likely lost your IMEI because of that. Meaning its not coming back unless you send your phone back for repair.

For international Variants use this guide

http://xdaforums.com/showthread.php?t=2420219
[LG Optimus G Pro] OsamaBT:
I know this guide has the files for E980, I had used the files for the F240s, offcourse not the E980 thats why I am confused why it happened in the first place.....besides the IMEI is shown but only when sim is not inserted :-/
[LG Optimus G Pro] hyelton:
Well no... Flashing a KDZ file which is what you would need to do to get back to stock is a WHOLE different method than flashing a TOT like this in this thread. You will need to flash back to stock what the phone is made for, if your IMEI is still doing the same then you will need to either return it or send it for warranty. Unless you backuped your EFS

Hi,

i need e986 dll and tot file please .

I have the e986 .kdz from here http://lg-phone-firmware.com/index.php?id_mod=25

[LG Optimus G Pro] hyelton:
the E986 does NOT have a Tot or dll..... Only KDZ you will need to flash it using the stickied method under the General section

[LG Optimus G Pro] jmenbalek:
Thank's but with the .kdz it's don't work :-/
[LG Optimus G Pro] hyelton:
You must not be doing something correctly. As .kdz files are going to be the ONLY method of going back to stock for you. Flashing .kdz files is a completely different method than doing what this guide is about...

Please Help!! Phone only boots into recovery after AT&T update.

Ok, here is my situation. I have an unlocked and rooted lg optimus g pro e980 (AT&T Version) running stock rom. It is on t-mobile network. The other day I connected to wifi and it said "AT&T update available" So being I am on a stock rom and it has been a little buggy lately, I figured an update wouldn't hurt. Well it hurt.. My phone only boots into recovery now. I originally had cwm on it and now flashed teamwins recovery on it. I tried installing stock rom with external sd with no luck. It always fails. When i try to flash a custom rom it still boots into recovery. Now, I started to follow the tut on how to flash back to stock rom and tried installing the lg drivers and every time i connect my phone it rejects it. It does show up on device manager with the yellow exclamation point but when i try to update drivers the same thing happens. I even uninstalled the drivers and reinstalled them. Still nothing... Please help. I'm sure I left out a lot of other things cuz my anxiety is kickin right now. I paid $450 for this phone and I wanna choke someone at at&t!!!

Antutu test results

I managed to flash both the e98010g and e98010k versions of the stock AT&T roms, although it failed on the latter (but it worked) and it got a Pass!! on the former.

I wanted to share screencaps of Antutu benchmarks from the 240 (Korean) phone, taken from a Youtube review of the stock phone and the benchmark result I got with Cyanomodgen which was 25463.

You have to take the battery out to initiate download mode by holding up and down volume while pressing power and inserting the USB cable. Once you begin the flash process you can put the battery back in to allow it to reboot at the end.

You can also boot back to recovery via hard reset manually. Press power and volume down and plug in power cable or usb. Then hit power when it asks you to do factory reset. It wont,this brings you back to recovery where you can do a restore...

Yes, this will get you back to stock

Yes, the process does work. The links point to the files you will need. The LG drivers are not the latest though. You can find the latest here: (as a new user I can't post the url. However, it is LG dot com /us/support-mobile/lg-E980#software

There are better step by step instructions elsewhere if the ones in this thread don't provide enough details. However, some of them don't include the correct files. The only thing I did differently was the process I used to go into download mode.

Plug in the USB cable to the phone

Press and hold both the up and down volume button.

Press the power button until the phone shuts down.

Release the power button (while still pressing both volume buttons). The phone will go into download mode.

Worked for me BUT...

Thanks man, although how it worked for was peculiar. I was at the most recent update pushed from AT&T which didn't allow root using the E980-UniversalRoot/Current Root batch file. I followed your instructions to the letter, when I went to plug my phone back in in Download mode it took a second.. then started running.. everything looked square. Loaded to 3% immediately (more or less) stayed at 3% for a minute, then loaded to 100% then said FAIL!! I was pretty worried, it didn't reboot automatically. I quit out of LGflashtool, unplugged my phone, took my phone out of DL mode manually by holding volume down+power. Then when it left DL mode I held down the power button to boot it up, it took a couple minutes or so, but booted up at stock, everything is working thus far and is at

I have never rooted nor attempted to root an LG Pro, I've rooted several other devices with some successes and some failures but have always been able to fix any problems myself or by using somebody else's suggestions/solutions. At this time it seems my device is working as it should at stock, BUT I would like to know, has anyone run into the same issue & is it okay to continue with Root using UniversalRoot at this time? I apologize if I'm an idiot and didn't attempt to look for a similar problem/fix on another thread thoroughly, but I thought this applies to this subject.
