I'm glad my phone cannot install the security update once it is downloaded. I've tried it three times and during the install the little Android falls over and gets a nice red triangle with ERROR! At least I can still use it! Sorry to hear about your bricks!
Update came OTA this morning. Phone bricked while in the process. Won't boot. It doesn't get anymore secure than that. Good job T-Mobile.
Wenn the update is coming to Europe I own a V10 LG-H960A (what ever it means). Nonteheless the LG is working much better and quicker then f.i. Samsung Note 4
Please keep updating this phone with security patches, improvements and new firmware for as long as possible, bc V20 isn't looking so great rn lol
