How did you get a network signal without imei?

1 download and install LG flash tool
2 download DLL file
3 download and install LG drivers
4 make sure the phone is charged at least 20%
5 turn off the phone using these codes
103729
L310MC570G
6 run LG flash tool selects that kdz file https://lg-firmwares.com/lg-lmg900n-firmwares/

(only Korean software will work )
select the DLL file and press ok and then starts

7 hold volume up while the phone is shut down and plug the USB cable
The phone will go to download mode and start flashing if not go to the device manager choose the port and change the port to port 41

After finishing flashing you will find the fingerprint is not working go to Google and search LG hidden menu APK download install
Use code #*462633*#900#

Go to svc menu -fingerprint - enable
Then go back to and go to devise test - manual test - handprint test and do it you know it's worked when it says fail

Sorry to bother, but there are 3 different Korean ROMs KTF, LGT and SKT, which one do you recommend downloading?
And can I download the latest Android 11 and flash that one directly?

Any one doesn’t make different
And yes you can go straight to 11

in the page sort the update by date and chose the newest one latter if you want to update you can flash again but all data will be erased
I couldn’t make the ota To work

Gents,
Could you please advise how to remove Warning message which appears after every restart:
'current version is not available for user. can't find matched carrier. Check NT-Code: FFFFFF : 84'

Go to hidden menu then go to mid info change tn number to Korean models
But you losses the 5g network

so try multiple tn number until you find the one good with your carrier
tn numbers

    Should you find a root for it Magisk may fix it
    No way,friend.Just because for root,needed to be unlocked bootloader,but on demo version this is impossible,cus he doesn't give device id for unlocking

    I am able to disable retail mode with root junkys guide. Ill post it below. Credit goes to root junky for the disabling retail mode guide. I am currently trying to flash another software KDZ on a retail mode LG Velvet 5G. I run into this error in LGUP. I am using a modified LGup file. has anyone been able to wipe these phones. i saw another xda member claim that the LG wing will flash in LGUP but I cannot figure it out. i tried all options in LGUP. Any IDeas?



    click on the retail mode app and put in the password
    password 103729
    click on factory data reset in the app and put in admin code
    Admin L310MC570G
    wait for the device to fully factory reset. Once it boots up quickly go into setting about phone and click on the build number 7 times then go into developer options.
    open a adb windows on your pc and start adb server with with adb devices.
    then toggle usb debugging and click always allow.

    disable device admin
    adb shell
    am start -S com.android.settings/.Settings\$DeviceAdminSettingsActivity
    uncheck retail mode admin and deactivate it.
    reboot from the shell with reboot.


    Uninstall retail mode app
    adb shell
    pm uninstall -k --user 0 com.lge.retailmode
    reboot from the shell with reboot.

    Demo mode locks removed

    Hope this helps those out there that needed it. The battery will still only charge to 50% but everything else will work as far as i can tell so far.
    Rootjunky Out.
