[Q] Flashing baseband F180K

Hello,
I tried to flash my korean F180K.
Changing ROM and rooting wasn't a problem but...
I downloaded ROM:
lg-phone-firmware com
For Polish provider Plus: 93 PLS/PLUS(POLAND) 10D LGE975
Changing ROM went ok i got the phone to factory settings and rooted.
I tried to flash baseband with adb and firmware_f180k.img.
Unfortunetly i didn't get any signal 2g/3g/lte.
On the unblock screen i got a message wrong sim. Like out of nowhere Simlock apeared.
Does anyone have working f180k baseband and could share a link?
I need it for operator that works on: 3g 900/2100, LTE 1800 MHz
Right now im back to Olleh Firmware

Someone got any ideas ?

Hi,
here my baseband:
https://www.dropbox.com/s/0h7motxqax7tmr1/firmware_f180k.img
https://www.dropbox.com/s/3g2pmgo22vdh43h/Flash Baseband - F180K.bat
you have to copy in your sdcard and then you can run the batch file. You need root, obviously.
Question: can you see properly your sdcard? I tried to convert my f180k too, but I could go further because my sdcard was not properly mounted...
Good luck.

I tried the process one more time.
Flashed the firmware, factory settings, root.
About flashing baseband after root.
I've put the phone in PC suite mode, it showed the built in memory and I've copied the img file there.
After this i copied the bat file to C:\ where already I had adb and ran it.
Everything works fine now accept WIFI/hotspot.
I did the same thing before the previous post and it didnt work.
Probably your img file was something else and worked ok.
Does someone have baseband where cellural and wifi works?
Thx

F180k successfully converted to e975(rom) network problem

I CONVERTED FROM STOCK KOREAN ICS ROM TO PHILIPPONE E975 ROM.. PERFORMANCE WISE ITS GOOD, LESS THAN 1GB USAGE OF RAM. BUT OHAVE THIS NETWORK ISSUE AND I CANT CONNECT TO MOBILE NETWORK.. WIFI AND BT IS OKAY BUT MOBILE NETWORK NOT WORKING.. CAN ANYONE HERE PLEASE HELP ME? MYCARRIERS BAND ARE 2100 FOR 3G and GSM ALL BANDS
EDIT: NETWORK PROBLEM NOW FIXED!!! SEE PAGE 2 OF THIS THREAD

did u flash basedband of f180k after converting to international optimus g..

Q: I'll ignore your advice,I still want to convert to E975 my korean model. What are the risks?
A: The hardware specs are the same, the difference is made by 4G(LTE) modem. Asia is using different LTE bands than Europe. So,you have to flash korean modem from HERE .Thanks houstonn for his work.

http://downloads.codefi.re/houstonn/lgog/modem/korean/cwm-lgog_f180k_modem.zip
flash it in cwm and u are ready to go..

. I gave him the same answer.

sorry kimitza i didnt see ur post...

Thanks guys!! I flashed the zip korean modem through cwm! But be warned imei will be lost so backup your imei first just follow the thread here somewhere on how to backup efs partition. For me i used manual method thru terminal and uploaded my backup in my dropbox for future use . For all those who will convert korean to international backing up ur efs is most important!!!

If you'll post exactly how you did it, i'll add it to FAQ,so it will help others.

So ,you used freegee to restore the efs partition?didn't this relocked your bootloader? I wanna understand this cleary,so i can put it for everybody

HERE'S ALL OF IT FROM BACKING UP to NETWORK FIX(THIS IS FOR THE KOREAN 180K)
1) FIRST OF ALL CREATE BACKUP OF YOUR EFS PARTITION!!!
http://forum.xda-developers.com/showthread.php?t=2164749
WHAT I DID IS THE MANUAL METHOD in the Terminal and transferred the 3 .img files to a safe storage(m9kefs1.img,m9kefs2.img,m9kefs3.img)
DONT USE OPTIMUS G TWEAKER FOR EFS BACKUP BECAUSE IT WILL REPLACE THE MODEM U WILL BE FLASHING THAT'S WHAT I NOTICED!!! BETTER TO DO IT MANUALLY
2)KDZ firmware update thru kdz updater (i used e975 PHILIPPINES ROM)
-KDZ FILES GREATER THAN 1GB WONT WORK IT WILL GIVE U EXTRACTION ERROR USE LESS THAN 1GB
3)AFTER KDZ update RESET FACTORY THRU HOLD VOL DOWN + POWER TO REMOVE CACHE AND DATA FROM PREVIOUS ROM (IF UR PHONE WORKED FINE AFTER KDZing ignore this step but i got a sdcard 000000 error so i used this step)
4)ROOTED MY PHONE WITH THIS http://forum.xda-developers.com/showthread.php?t=2181103
5)FREEGEED TO UNLOCK BOOTLOADER AND INSTALLED CWM TOUCH
USED PLAYSTORE VERSION (need WI-FI for this one)
6)DOWNLOADED F180K MODEM HERE
http://downloads.codefi.re/houstonn/lgog/modem/korean
7)COPY MODEM ZIP IN SDCARD
8)RESTART IN RECOVERY HOLD VOLUME UP + POWER THEN VOL DOWN 2 times THEN POWER TO ENTER CWM RECOVERY
9)INSTALL ZIP FROM SD CARD THEN BROWSE TO THE MODEM ZIP AND FLASH WAIT TILL IT IS FINISHED
10)EXIT RECOVERY AND REBOOT!
AFTER REBOOTING YOU DIAL *#06# it will show IMEI null window and Network will not work because u need your IMEI!
DONT WORRY HERE IS WHERE YOUR EFS BACKUP FOR YOUR IMEI WILL COME IN HANDY!!
11)COPY THE 3 IMG FILE IN ROOT OF SDCARD AND INSTALL TERMINAL EMULATOR!
12)MANUALLY RESTORE THE IMG FILES USING THE TUTORIAL IN NUMBER 1! REBOOT! AND THERE U HAVE IT!!!
NETWORK FIX USING F180K MODEM WILL ONLY WORK IN COUNTRIES WITH THE SAME BASEBAND AS THE ORIGINAL F180K MODEM
GSM900, GSM1800, GSM1900, UMTS2100 (B1)
LTE1800 (B3)
FORTUNATELY HERE IN THE PHILIPPINES ALL BASEBAND ARE COMPATIBLE!

Will add it to FAQ.
PS, you can use kdz updater with bigger files. Just run kdz updater in compatibility mode xp sp3 with admin rights.

Invalid sim card error after flashing E975 kdz

I successfully (??) flashed my F180k to E975K kdz/
everything seems ok, but I get Invalid sim error, and obviously cannot connect/
I tried to unlock the phone using freegee, running TWRP, with no success. should i run CWM 6.0.3.0?
Any other ideas why the phone is locked or how to unlock it?
thanks,

invalid sim got nothing to do with lock bootloader and recovery and freegee

the phone is permanently locked (!!) help...
Any ideas how to bypass it?

if it was working fine before try the same stock f180 firmware and see if that works, have no idea about sim unlocking on optimus G. search for that.

your guide is really great, I probably did something wrong. how can I tell if I am running the right baseband?
the baseband currently installed on my phone is APQ8064/MDM9x15M.
do you have another baseban file other than what you've linked to on your guide?
many thanks!

f180s

f180l

I flashed the baseband, but it is still permanently locked.
Any ideas as to how can it be unlocked? maybe if I will use other EFS backup?
will it be solved if I will go back to to the original KDZ?

have you backed up your efs before installing kdz? it may help you for working sim cards.
but if you revert back to orignal kdz baseband is a issue here again

Did u hard reset after flashing kdz???

This did not solve the problem.
The baseband fix seems to only fix the reception issues of the phone so that it can pick up the signal.
The problem I have is about the phone not recognizing the sim card. It will only recognize it when I go back to the stock F180K rom not the E975 rom.
By the way, all F180 phones are pre-unlocked by Korean law.

You do not need to touch the baseband if you already flashed the F180K rom.
The sim should be recognized and baseband should be the right one already.
If you need further info add jseo to kakao talk and send me a message and we can talk real time. I'm in Seoul

Hi Guys,
I need expert help here , it looks i brick my handset while i was trying to convert it into E975 by following the instruction
Guide
Regardless of which firmware you are currently running on your F180, you will need to download and switch to the corresponding one from the list below:
F180S : F180S20B_00.kdz
F180K : F180K20B_00.kdz
F180L : F180L20H_00.kdz
Tip: You can find your phone’s model by going to ‘Settings > About > Phone identity’ in Android.
Warning: Make sure your phone’s battery is at least charged 80%. Don’t proceed otherwise as LG Optimus G comes with non-removable battery and thus you won’t be able to easily swap the battery if it dies in the middle of the process.
It is mandatory that you factory reset your phone before proceeding. For doing so, go to ‘Settings > Privacy > Factory data reset’. Please keep in mind that doing so will wipe your phone including contacts, messages, mails, applications and all the data on your phone’s internal storage. Your phone will reboot twice. Let it boot after factory reset. Once you are on the language selection screen, power off your phone
Press and hold down ‘Volume Up’ + ‘Volume Down’ and while inserting USB cable in to the phone. This will get you to S/W download mode on LG F180.
Now you need to flash the firmware you downloaded earlier. Please refer to the guide here:
How to: Download and Install KDZ LG firmware – All Android models
Once the KDZ firmware is successfully flashed, your phone will reboot automatically. Once it fully boots up, go through the setup procedure and again factory reset it as you already did once.
Once you are on the language selection screen, power off your phone
Once again, put your phone in download mode
For converting your phone to E975, we’ll be flashing this E975 Hong Kong KDZ:
Follow the same procedure for flashing KDZ as you did earlier.
Once the KDZ flash is successful, go through the set-up procedure. Now go to ‘Settings > Storage’ and make sure your internal storage is being listed there. If it shows “0.00 GB” there, don’t panic. Power off your phone. Once completely off, press and hold down ‘Volume Down’ + ‘Power’ buttons until the phone displays a hard reset screen. Release ‘Volume Down’ and press ‘Power’ twice for resetting your phone.
Your phone will reboot once again and your phone’s internal storage will be back to normal.
Now you need to root your phone. Please refer to our LG Optimus G universal rooting guide here:
Universal root for LG Optimus G – Any firmware
Once you are done with rooting process, make sure you reboot your phone at least once if it doesn’t reboot automatically.
Now we will be flashing LG F180 baseband. Download your corresponding baseband backup from the list below:
F180S Baseband
F180K Baseband
F180L Baseband
Unzip the downloaded archive and you will find a batch file named ‘modem-flash’ inside it. Make sure ‘USB Debugging’ is enabled on your phone and your phone is in ‘Charge only’ mode while connected to the PC. Run the ‘modem-flash’ batch file.
Keep an eye on your phone screen as you will need to tap the grant permission button on SuperSU pop-up. If you miss the pop-up as it expires after 10 sec, run ‘modem-flash’ batch file again.
Once the baseband has been flashed successfully, reboot your phone
Congratulations! You have just converted LG F180 to LG E975.
it converted successfully but when i insert sim in it says invalid sim card , i have updated the base band given in above link but no luck then i tried to flash the original rom with many version for this set same thing again ,no signal no network .i think i mess up with the orginal modem without taking any kind of backup.
I need expert advise here how to fix it and which kdz to use to fix it.
looking forward for your reply.
Thanks,

@ranadawood: Flash original kdz file for your respective model to get back network ...
