Hey! does this work on LG Velvet 5G UW (LMG900VM) (Verizon)? network unlocked after flashing?

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.

Thank you for the great advice !! I have been able to remove the retail mode from my phone but I would like to get access to the play store. I would also like to get rid of the 50% battery barrier. I read about the flash method but I'm it's not so fully comprehensive for me on how to use it. Is there a possibility that you could help me pls ?
lg velvet 5g
android version 10

Hey everyone! Im new here so forgive me for doing anything incorrectly.
I have managed to get Android 12 onto my retail mode LG Velvet 5G.
1) Download the KDZ

Download LG KDZ Firmware G900N30B_00 / KTF of LG Velvet 5G (LMG900N)

Download LG KDZ Firmware G900N30B_00 / KTF of LG Velvet 5G (LMG900N) for free and max speed from LGROM.com.

lgrom.com

Here is the link for the KDZ (link provided by Mr.PvT).

2) Flash with the LGUP 1.16 from this link:

LGup16guiVelvet.zip

grabify.link

(Provided by 0x0null, just scroll up a bit)

And youre good to go! Everything seems to be working fine on a cursory glance (Minus LG SmartWorld ofc).
I cant test calling, and data, so one if one of you can also get it working, please do detail if 5g or VoLTE or Wifi calling are working for you!

Here are some screenshots:

How did you get a network signal without imei?

Has it been confirmed that devices lacking an IMEI under demo mode, gain one after flashing a valid kdz, or is additional hacking required?

I picked up a retail mode Velvet 5G with only a CSN number listed on the sticker (no IMEI).
Model: LM-G901V
Software: G901V10d

I made a backup using the bkerler/edl script. Here's a (slightly edited) excerpt of more model info from the lun0/els partition:

Could this be a Verizon variant?
I'm looking for help on how to cross flash this with the most recent OPEN_CA image for G900UM, or if that won't work, whatever is most appropriate. Thanks!

Was an IMEI auto-generated after you flashed one of these ROMs?

If rom on Android 10 and you want to use Google Pay . Can generate a some IMEI in Hiden Menu

 

[skyblaster]

Has anyone ever succeeded in either of the following with one of these demo units:

1) Getting an IMEI to be autogenerated?
My original fsc and fsg partitions read back empty, so I'm guessing the answer is no.

2) Getting an OTA update?


EDIT: Also, I'm interested in an ftm partition from a non-demo LM-G900UM2, if anyone would care to share. Thanks!
