Help please

OK, i have a friend who purchase an LG 980H (i think it has the Korean version) and he try to put the Telcel version, all the process was OK but at the moment the de vice has to restart it doesn't do it, even we can't turn it on, i wish some one will help us to save his phone, we follow the guide perfectly no problems during the installation or with some step, please can you help us?.

Main issues:

The device can't be turn on, we can make the device make a hard reset and also we can't make the device be on download mode again.

Plus:

He make the firmware change with windows 8 654 bt.

Thanks in advance!

Flashing ATT firmware to international

Thanks for the great guide! I have two questions. I have a G Pro E980 with the latest AT&T firmware and i want to flash it to international. BUT, i want to flash it for an E986 Hungarian version. Is it possible, or it will burn out my phone? And if not, what languages are built in the panama E980 version?
[LG Optimus G Pro] hyelton:
Flashing it to the e986 will cause you to have signal problems and you will only have 11gb of storage instead of 24gb.
[LG Optimus G Pro] ocieno:
Joe3681 is there a link to that actual flash tool?

[LG Optimus G Pro] hyelton:
The current kdz for the files are on my server. So if you downloaded it from me its the latest. And since your running E980h panama on an E980 no OTA updates

hallo iam from greece i bought an e980 at&t from us. is there any stock rom with my language. thanks and sorry for my english.
[LG Optimus G Pro] zxaz:
Then you need flashtool...the att rom are tot file...you have 2 software from lg.....one for kdz and the other for tot file......
[LG Optimus G Pro] NWinfuse:
ok, you tell me there are two softwares but not which one I actually need. When I run uptest.exe which I think is what everyone refers to as the LG flash tool that program appears to only allow for a kdz file, what program should I be running that will accept a .tot file? Is that program included in the downloads from the OP, if yes I have it downloaded just need to know what it is called.
[LG Optimus G Pro] Silverknife:
I F240S (Korean version)

I was using MIUI but thought to return back to stock so downloaded the .kdz file (f240s10z) for my phone as i remember i was having 10z verison. Flashed it as mentioned in the thread, everything went fine phone restarted at 93% and it continues to progress till 100% afterwards i detached the phone. Now the phone is stucked at SKT bootscreen, i waited like 5 mins but its still there with skt animations.

I flashed it like 10 times but still the same. i thought may be iam flashing wrong file i downloaded 10x.kdz file and then flashed again but it was stucked at 93% and gave error.

So i flashed 10z file again software completely flashed again but still the sk telecom screen. Iam unable to do hard reset via vol down plus center key and power button but nothing happens.

I can charge it using charger and shows the animation. Can anyone guide me what iam doing wrong? or how to solve this problem?
[LG Optimus G Pro] mandarjoshiin:
I have bought LG OGP from USA which had AT&T unlocked version. Currently I am using Kitkat rom.. So my question is, if I flash the *.tot & *.dll files via LG Flashtool, will it lock the phone again to AT & T? Or it will remain unlocked, how I had received it ? :confused: I want to go back to Stock.. and flash G2V5 back.. Please help .. :fingers-crossed:
[LG Optimus G Pro] clippy83:
It will be just like when you first got it
[LG Optimus G Pro] mandarjoshiin:
Yup! Got it unlocked only.. :good: I am back on G2 V5.. :victory:

---------- Post added at 11:02 AM ---------- Previous post was at 11:00 AM ----------

Bro.. if you want to flash .tot & .dll files, you need to use the LG Flashtool v1.5, normal flashtool wont work..

Get the LG flashtool from here...

http://xdaforums.com/showthread.php?t=2302660

You'll require a serial key or dll file in order to make it work.. Search on google for the same.. :good:

Happy flashing.. :)
[LG Optimus G Pro] kemenydani:
Hello! I am from Hungary and i have an AT&T e980 too. I flashed it for the panamaE980 version to remove the atnt stuff. It doesn't includes the greek language but people said me that it's the best rom for e980 if you want to flash it.

Btw i asked the same question like you but someone told me that flashing for an another version like e986 will cause some problems with the storage for e.: if you have a 32 gigs phone it will show only 16 etc.. So it's better and SAFER if you plash it for the panamian E980 an use it with english language.

If you decide that you gonna try to flash it for an another version of the rom, please notify me how it works, i'm really intrested.
[LG Optimus G Pro] hyelton:
If you flash back to stock the phone will stay unlocked

Thats incorrect. It will NOT relock the phone.
[LG Optimus G Pro] notohp:
To silverknife:

I had the same problem. As a work-around, I first flashed HK kdz which obviously had only 16GB sdcard. Once done successfully, I flashed F240 on top of it. As pointed in the OP, seems like this process requires a hard-factory-reset which it may or may not do. In HK version, I could press power+vol-down to force a factory reset but could not do so on f240 cuz I dont get that option.

Once the phone booted after flashing f240, I did a factory reset from the settings and got it working :)

Hope this helps.

[LG Optimus G Pro] umanyar99:
Thanks a bunch

THANKS!!!

This worked great. The 980h panama version is better stock...runs awesome even more. I had a problem after I accidentally downloaded an OTA patch a few days back with my rooted stock rom. But instead of settling for something less, the e980h version was even better than what I had.

Update Issue

Hello,

It looks like there was an update to the LGMobile Support Tool which now broke this method. I did this method to install the Panama version on my LG OG Pro previously, however today it won't install custom KDZ. LGMobile Support will launch when selecting Upgrade Start from R&D and LGMobile Support says that the phone is already up to date. It seems like there's an update pushing to the R&D Tool as well. I blocked connection to R&D Tool on a clean install of Windows and when I select Upgrade Start in R&D, it will say I need to update my version of the R&D Tool.

Any Ideas?

[LG Optimus G Pro] Lg optimus pro:
Hi,

I used this guide for my Lg Optimus Pro G F240S and got success, I thought..

Instead my phone keeps starting as SK Telecom boot up and after that the message "LG IMS has stopped". I am living in Sweden and bought my phone in Korea. I downloaded the latest stock rom according to your link.

Do you know what the problem might be?

Regards Tor
[LG Optimus G Pro] hyelton:
Hate to say it but there is no way to change the bands on the G Pro :/
[LG Optimus G Pro] hyelton:
Have you tried performing a reset afterwards?
[LG Optimus G Pro] chizhk:
Thanks to all for this nice and fruitful thread.

I did what was explained in the guide which appears in the beginning of the thread and everything worked as expected, however after playing with few different stock ROMs (trying a few of E98x modifications) and having fully functional phone, I decided to get back to my original F240L. The installation was completely fine, but I can't get into hard reset (Power and VolDown keys) no matter what I do. Pressing them at the same time gives nothing and the same black screen stays on. If I boot (it boots fine) then the launcher fails ('Unfortunately, Home has stopped' message) which prevents me from doing anything with my phone. Thus I am completely stuck with nice white brick(no Recovery access as I can't install it either) :(

I tried the original F240L Rom installation a few times more according to the guide but it was the same after each attempt (no hard reset and launcher failure if I boot)

Anyone can give any idea what can I do?
[LG Optimus G Pro] chizhk:
P.S. Getting back again to the previous ROM I tried to use (.kdz file for E989) was OK in terms of boot (the hard reset option was available while pressing Power and VolDown keys and worked fine, so the phone booted successfully). However (and this is why I had to return back to the original F240 in the beginning) the phone does not connect to the network at all (emergency calls only and "Your SIM card does not allow a connection to this network" message if I try to use Tethering and Networks'->Mobile networks->'Network operators'->'Select automatically' option and "No network found" if I press 'Search network" menu, this is despite the fact that I use a valid SIM which belongs to one of the carriers here and worked just a few hours ago before I started playing with these ROMs).

On the other hand, I can't install any application (only via Play Store) manually (and as the result no rooting too) as it looks like the device does not see any storage (having "Empty folder" in File Manager application and "Operation failed" if I try to create a file or a folder under /sdcard (read only mounted FS under /storage?).

And when I try after that (once again) to install my phone's original F240L .kdz file, the same problem occurs - the phone is able to boot but the launcher fails and hard reset does not work after I shut it down (the LG logo comes up and is stuck after that when I press both Power and VoldDown).
[LG Optimus G Pro] chizhk:
P.P.S. Successfully overcame the hard reset issue (had to press Power+VolDown+Home instead of just Power+VolDown).

but 'Unknow service' issue persists. After reading the posts in the forum I have to admit that it looks I damaged EFS because of flashing a ROM which is incompatible with my model (F240L). So, now I have stock F240L Rom with no network connection (only WiFi) and 'Unknown' under IMEI information. Posts about fixing the EFS are controversial. Anyone can advise?
[LG Optimus G Pro] hyelton:
My understanding of it. Once its gone or screwed up unless you have a backup there's no fixing it. Back when I had my G Pro I found that to be true when loading ROMs that had a different baseband. Mainly the Korean stuff on an E980. I had a backup and I would load it and bam I'd get service again but without it I couldn't use the phone.
[LG Optimus G Pro] chizhk:
The issue is solved :laugh:

The solution was installing the Panama LG Optimus G Pro ROM (Panama E980H10A_00.kdz) on which I suddenly started seeing my correct IMEI number) and then flashing my original F240L ROM. All is back :))))))

Lessons learned:

1. Do not mess up with different ROMs for our LG OG Pro (F240 vs. E98x flavors). Use only your sub-model ROMs (all worked perfect as long as I used F240 ROMs)

2. Must have full backup available at safe place (at least SD card but SD card + PC is better)

need help/advice 4 OTA UPDATES

Hey. Need advice. I live in Ecuador. Bought my g pro e980 att off ebay and bought an unlock code to unlock it. Worked. Got it on Movistar. My issue is I want to receive OTA updates. Can't. What can I do? I'm still stuck on 10k. I can't even use dual camera. I would perfer not to root. Is there a way I can flash yet still receive OTA updates? I'm not that knowledgable on flashing, rooting, or jailbreaking. Successfully broke and restored an iphone stuck in several different recovery modes. But still an amateur. I've read at least 30 pages off this thread. Still not sure if flashing, lets say the panamanian one will help. Mine is 32 gb and I don't want to lose any of those. Can someone please guide/help me. I don't even now how to backup my phone. (Esl think it is) Will I lose my unlock? Would I b able to just put in the same code if it does relock the band? Someone lend me a hand and some experience. Don't want 2 mess up my g pro. Love this thing.
[LG Optimus G Pro] hyelton:
Sorry no OTA updates for the e980 on a carrier other than att. You'll have to flash the latest using the method here.
[LG Optimus G Pro] kingrise:
Thanx 4 the quick reply. Not happy 2 hear that. So if I flash the one on this thread it'll put me on 10p? And I'll have 2 flash everytime there's a new update. That sucks. And anything on the unlocked carrier? Not sure if it's worth it.

2) Go to Phone Information

3) Change the dropdown to "LTE Only" or "LTE/WCDMA". You can also choose "LTE/GSM/WCDMA" but it will revert to "GSM Auto" when you restart the phone.
