i follow instructions exactly i download tot and dll for ls980 but my phone says that is a d802 but the back of my phone says ls980 and is a sprint version but my phone says d802 so when i try to use lgflashtool everything go ok but after waiting for conection says wrong model number or check dll

Like the title says, i'm having a hard time unlocking my S3 running Cyanogenmod and 4.4.4. Is it the fact that it's running Cyanogenmod and not a stock ROM that's the hold up? I bought an unlock code from 2 websites and they don't work.
I'm running: CyanogenMod 11-20140805-SNAPSHOT-M9-d2lte
Android version 4.4.
Baseband I747MVLUEMK5
You need to be as close to stock as possible to unlock via code.
delete
err on the side of kindness
I am having the same problems... 4.4.4 and I forgot to unlock it first. I can't downgrade and I can't unlock via code.
Are you running a stock ROM?
Revert to Stock

I tried with my offial att unlock code 5 times (which I thought would permanantely lock my phone while using the Slim Rom (4.4.x) . I reverted back to stock and followed the procedue at an external website that I cannot link to because I haven't posted enough. Just search 'galaxy s3 unlock code doesn't work' in google and you will find pages that give you some ussd codes to get into the debug menu. I followed those directions and when I rebooted and entered the code it worked.

Need little help from you.
Do you rememeber which stock image you used? What was the baseband version?
Back to Stock from CM11 and SIM unlocked
I was able to ODIN to stock ROM and SIM unlock the phone.
Background: My ATT S3 i747 was running CM11 Android 4.4.4. Baseband and Bootloader was I747UCDMG2.
Steps:
1. Flashed rooted stock ROM (root66_ATT_I747UCDLK3.7z) using odin from http://forum.xda-developers.com/showthread.php?t=1739426
Followed the steps in OP.
After flash ODIN showed PASS and phone rebooted. It was stuck in Samsung logo. I booted into recovery. Performed a wipe cache and factory restore.
Phone rebooted successfully after that.
2. Inserted non-ATT SIM and it asked for the unlock code. I had obtained the code from ATT before. Used the code and phone was unlocked.
The same unlock code did not work while I was running CM11.
NOTE: When running stock ROM you can follow steps in below threads if direct unlock did not work for you.

2. http://forum.xda-developers.com/showthread.php?p=38767845#post38767845 This works only with stock 4.1.1 image (LK3 modem).
See http://forum.xda-developers.com/showpost.php?p=59029460&postcount=323
NOTE: If you need TWRP recovery, see http://forum.xda-developers.com/showthread.php?t=1739426 and search for "Odin Flashable TWRP Recovery" in OP.
You can download ODIN flashable TWRP from there.

I have a Tmobile UK phone running a Cyogen ROM. I want to move to different network (GifGaf), but upon inserting the SIM the phone requires unlocking. I've got the codes for unlocking, but they don't work. After a bit of search it appears that I can only unlock my S4 mini with the official ROM installed which I must admit surprised me.
Therefore does anyone know where I can find an official Tmobile ROM for a UK S4 mini ?
Hi !
You have all firmwares you want at "Sammobile" (internet site) ,it's official and you must be registered for to download ,it's free (with slow download)
It's a known problem...impossible to unlock sim with customs by "classical" way (and i don't know if it's possible by hack)
In theory,you can flash again a custom recovery and after a cystom rom without loose sim unlock...
Be careful !!!!! Don't loose the number of sim unlock !!! Because if you want to flash customised firmware (ste ,N5...) => there are chance that the phone will be relocked at your T-mobile !
I don't know exactly but it's a possibility because i have see that on a old S2 updated with officials => it loose sim unlock after .
Thanks for the info.
Do you know if its possible to re-install the official ROM using Cynogen recovery or do I need to replace that also?
Reason I ask is that I tried installing the official ROM last night in Cynogen recovery and it aborted almost immediately.

open phone . take out mother board .. and read plaque model. if sprint flash sprint KDZ and LGUP. if H815 then do that .. thats the only way to be sure.
U have a refurbished model.Go to nearest mobile repair shop & take out your motherboard to see what model no is written on this.Then flash a rom accoringly. Don't flash any other rom just by assuming else you will brick your device.
Yes my phone is refurbished...
But how to flash the rom?
If I found it to be a sprint version and flash a sprint rom ...it will be locked?I am using phone in India...
Any chance to root the phone and install twrp?
Then flash a custom rom?
Please help...

Most probably it will be locked cause most higher Android versions LG has blocked rooting or unlocking..But you can always browse few threads.
Mine is also a refurbished model with F500L motherboard,LS911 body & had H815 global rom installed out of the box.I am currently on F500L Nougat locked & unrooted..I have tried almost every method.It failed to root & even to enter fast boot.
If you get your proper model no on motherboard then just flash the rom with ToT flasher in download mode with respective DLL.

Thanks for your reply...
Your network is locked?
You cant unlock it?
Can we degrade our Os to lollipop to get root?
Even I cant turn on the Enable OEM unlock under the developer mode...
Any more advices?
Please help.....
I have tried almost all h815 ans ls991 roms with all flashing methods but still unable to successfully flash my device...lg tot flash tool always show dl error after 4 to 6 percent of flashing...
Please help
Any idea's?
Pick the phone, and send it to the place where you bought it. If you have warranty the repair is free, if not, then you must pay sadly.
Still no solution, I even cannot enable OEM unlock under developer options...
It automatically disables it...
Please help
Just experienced this issue after changing sim card... Call and Camera stopped working over and over again.
How I solved it: Go to the specific app that is causing you trouble, and clear cache/files (too bad I only found this after 3 factory resets).
Maybe it will help ... LG G4 CAM
