UM7xxx is from LG's cheap line and you can't expect much..

just reset your tv to factory default and everythin will be fine..no need to mess with firmware

I did not try.. You can try it, but there is always a risk of destroying the TV. 🤔

As far as I can see you installed a BETA 05.10.02 long time ago. LG Company did not allow firmware to be downgraded. You'll never get official update because official firmwares starting with 05.05.xx but you have 05.10.xx, so only way is unofficial downgrade to latest official for your region (Brasil). Process is a bit complicated and here on this forum you have detailed tutorial how to. HERE IS TUTORIAL Attention: You can destroy (brick) your tv set if something going wrong in the downgrade process. Cheers! Dejan

This is OFFICIAL firmware update, but only for Russia!!! New in this update: 1. Improvement 1) Apply TLS 1.2 http://www.lg.com/ru/support/support-product/lg-42LB730V

I would not recommend unofficial downgrade if you do not know in detail how it works. Wait for the official update.. There is a risk that you brick your TV

This is file for europe region, so answer is NO

Just download 05.05.20 officially from LG site HERE Unzip "Software_File(Version_05.05.20).zip" , format usb flash stick to fat32, create folder LG_DTV and copy file "starfish-dvb-secured-m14tv-25.ashley.m14tv-2522-05.05.20-prodkey_nsu_V3_SECURED.epk" into this folder, safely remove usb, plug into TV and install...or wait a while LG prepared for us new firmware update 05.05.35 (now in test/beta)

Hm..interesting. For me, just disappear channel(black screen) while seeking new version, but only in LiveTV...not in HDMI. Maybe another beta flashing?

I think you should reset to factory settings and try if this problem appears then flash new beta. BTW there is another beta/test 05.05.35. Read my post here
