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.

you need to flash f180 baseband, 1st check your f180 S or K or L then flash baseband made for your variant

BTW, I was following your (great) instructions. probably did something wrong while trying to flash the baseband. I will retry.

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!

i dsnt post any guide on here or any where,okay?
here are the links
f180s
f180k
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

Invalid sim card after converting E975

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 ...

Try another KDZ method. your .kdz file is probably > 1GB so maybe this can work.

Dear olcimanic,
Thanks a lot Borther. I can flash my optimus G by F180s jellybean. But after that i have the problem of network fluctuations and sometimes no network. what can i do brother? please make a way for me.
regards

Clickanu,
Try to flash the latest 4.1.2 for your phone's original model(the model, when you bought it F180S i believe), through kdz. But remove the Sim card before flashing... Once successfully flashed, Please setup the phone for initial setup without the sim card. Once set up is complete, switch off your phone, insert sim card, reboot and search for your network operator manually, sometimes automatic searching doesn't work well.. this is just an idea, not sure, how far this will work, also, always keep in 2G, use it for sometime or somedays and then start using 3G...

Dear olcimanic,
Thanks for your suggestion. Actually i am from Bangladesh (in asia). I found this phone as a gift, when i found it, it was F180S. But The logo behind the phone is from Olleh. Can u please suggest me, how do i find the original stock firmware. I have lot my IMEI after flash...please Help.

LeEco X800 Le 1 pro US SIM and IMEI lost

Hi.
I bricked my LeEco X800 Le 1 pro and when I recovered it doesn't recognizes sim and the IMEI number is 012345678901234.
The radio in Phone info is off and I cant turn it on.
Preferred network type can not be changed.
I tried to use QPST to change IMEI, but it does not connects fully.
Tried rom vresions:
Le1PRO_US_X800-ROW-PB-v60-CUOCO92-5.5.014S.zip
Le1PRO_US_X800-ROW-v48RL-CUOCO92-5.5.011S.zip
I used QFIL to unbrick my phone and then it had 8gb rom so i formatted phone.
Now everything is ok except IMEI and sim problem
Help!

I have the same problem. No imei. Phone does not detect Sim card.

There is already topic about this here http://forum.xda-developers.com/leeco-le1-pro/how-to/imei-lost-imei-letv-1-pro-x800-brik-t3430035
We need a QCN backup from working phone to solve this.

Please Try my QCN file from my working phone.
I used Qfil for backup.

The user "mariocolino" from Forum.le.com has confirmed that this QCN backup has fixed the signal problem.
I hope it will help other X800_us owner with the same problem to repair their phones.
Some helpful tools & files.

Use this brush tool. => https://1drv.ms/u/s!AidiAJYxvGs2cPhtLogbcsqjYEo
It will get back all system defaults.
BUT WARNING!
It has a malware that installs apps itself.
After brush tool install custom ROM like cuoco92

if 4G doesnt work, try flashing the Non-HLOS from an x800 US image
Yoy can also see if you can activate the bands on the QCN file with QSPT

If you flashed your phone and still no network it is probably a hardware issue.

It can search signal after I flashed a QCN file , but it is not stable , it losts signal sometimes , and need to reboot , so I think it is the problem of hardware , I am finding another file , I will try again .
Or can you backup QCN for , and remove sim card when you backup .

Can you send me the link of the QCN file to download cause i have the same problem..

No one should provide their QCN file because it contains the IMEI of that phone.
You don't have any network, right? What is your ROM, modem version, G3 model? There is a menu to manually select the network in the settings. When you go there, does anything appears?

What board version do u have ? I lost my imei too when unbricking with Test point via edl
I couldn't restore my imei can u tell me your Telegram so I can ask you some questions tjnx

Try searching for these terms on google. "deadboot repair" "edl" "firehose". Usually after flashing a deadboot repair package the imei resets by reading the chipset. Goodluck.

To my knowledge the imei value is stored/burned in the soc on all snapdragon chips. I am not sure why it did not auto regenerate after an edl flash.
