Orginal Title: Sprint LG V50 may get Android 10 beta by End of 2019 (V450PM)

I saw this article here: https://www.mylgphones.com/sprint-lg-v50-thinq-5g-android-10-update-will-release-soon.html?amp

Leaked Frimware details:

Model:LM-V450PM

Size:1508.11MB

Android Pie 9.0: LMV450PMAT-V10p-310-120-SEP-19-2019-ARB00+0

Android 10 Beta: LMV450PMAT-V18a-310-120-OCT-29-2019-ARB00+1

File name: LMV450PM-V10p-310-to-LMV450PM-V18a-310.up

The article source won't release the beta frimware though. Anybody know where/how to get this or convince them to share it? However though, this is great news!

Edit: Special Thanks to chortya for purchasing the file. The link to download the file comes from the domain dl01.gdms.lge.com which is a legit source from LG directly. The file received is a .mo file, you just rename it to get a .up file. chortya has graciously shared the OTA file in the mega.nz link below!

https://mega.nz/#!gjJi3KiK!ebsQdxmnXtEYRiG69F5oAlVqNnsZ3c9D7SpWahGI8OQ



even patch name stipulates specific old firmmware version. And yes, I am on v10p.

Now lets figure out how to flash it!

Edit 2: Wow, that was fast! Thanks to aiap for figuring out how to flash this OTA.

SUCCESS!
I ended up not using LGUP, instead this is how I did it. (Make sure to backup, for some reason I had to factory reset because mine was stuck rebooting after "android is installing" notification completed.)

STEPS:
1. Download .up file: https://mega.nz/#!gjJi3KiK!ebsQdxmnXtEYRiG69F5oAlVqNnsZ3c9D7SpWahGI8OQ (thanks @chortya)
2. Rename file to LGUP_FOTA.up
3. Place file in root of internal storage on V50.
4. Download "Activity Launcher" from Play Store
5. Find FOTA Update
6. Hit the first option (com.lge.lgfota.permission.FotaTestActivity)
7. Follow prompts.

Edit 3: Some screenshots thanks to @aiap

I am not able to install it. Tried multiple options:
- LGUP FOTA upgrade - device protected error
- recovery mode - both SD card recovery and adb are not working. SD card mounting fails and it seems that my V50 is not connecting to PC if in recovery mode so adb does not see it. adb works fine with phone fully booted, so developer options are enabled and phone is authenticated with pc
- lgup_cmd does not even recognize *.up files

Any thoughts?

Does it make sense to move this to the kernel/firmware section?

Yes. You must flash it with LG-UP 1.16.0.3.
Install lg USB drivers 4.4.2
Install lgup 1.16.0.3
Install lg common dll 1.40
Download and Copy the ui config file (from the LG-UP thread here on the forum) and paste it where the common dll is.
Then enable USB debugging in dev options
Then connect to pc
Then start lg up
Then chose FOTA upgrade
Then load your android 10 beta fota file. Make sure it has. Up extension
Then click start on lgup. Wait for the minute and it should start flashing.

My setup is exactly as you described. I need to check the version if the USB driver, but don't think this will improve anything.

As I have written I am getting "protected device" error.
My V50 is locked, does it have any influence?

If you have the right ota it should work.
And also the correct security patch. Maybe this is why it's not working...

    Woah, I was not expecting that! That's awesome. Can you share screen shots? How stable is it so far?

    Use ADB to reinstall. The app can't actually be deleted it's just deleted for user 0 so you can add it back by typing:
    adb shell cmd package install-existing <name of package>


    Factory reset will reset all data on current ROM but it will bring back the bloat. This is at least what I understand, feel free to correct me if I'm wrong.

    Just wanted to say THANK YOU. Worked like a charm. BTW, I've certainly removed "com.lge.lgfota.permission" from my delete bloatware list! LOL

    Well done! I tried similar approach but with recovery mode and it did not allowed mounting sdcard. It seems that hidden actions are important with Sprint :)
