I wish I could be more sad about this. LG lost a lot of trust during their bootloop era, around the time of the G4. They had some interesting ideas with their V series, but I just couldn't bring myself to trust them after my G4 died in less than 18 months.
I have two nexus 4's with bootloop, Nexus6P faced bootloop too but that's because Qualcomm messed up S810,S808 so bad that it had physical core separation. Both LG & Google had to face settlements for it. There were reports of Pixel devices facing bootloops too. I've decided not to buy flagships until it's at least a year in the market.
Btw, Nexus6P bootloop can be fixed in most devices by disabling the 4 Big. Cores and the phone can be used for less-demanding tasks with the 4 Little Cores. My Nexus6P has been resurrected this way[1].
I don't know what model of phone it was, but I had an LG phone lockup after a system update. I called support and they said it was out of warranty and I could send it in for repair at my cost. I never bought an LG phone after that.
It's just not possible for a company to push out a software update that bricks your phone and refuse to fix it in a competitive market.
