Unfortunately I couldn't recommend the 5x, had 2 both boot looped. Had one completely replace by LG to one that looked new, and that one started looping about 6 months later. I tried to make it work, it's a solid phone but not worth the time. I got a use pixel and it's super solid phone. Save up a bit and just go for a newer phone. I always buy used that are a bit dated. Hope this helps!
Hey, thanks for the feedback! Does your 5X still work after all this time? I'm looking to buy one of these chinese modded Nexus 5X motherboards to revive my old 5X! I understand the heatsink mod is crucial to avoid further bootlooping, so I was about to order the copper pad until I saw your comment (and LeonF's) about it causing GPS issues. I'm glad you posted this because now I'm ordering Arctic thermal pads instead.
I was just waiting for a price decrease and this seems like a good time to buy the motherboard. I can't post links (new user) but there's one on AliExpress that has 4GB RAM/32GB ROM and currently costs 78 USD because of the winter sales!
