I did fixed mine, i replaced my internal battery... i couldnt find MS414GE (3V 2mah) battery but i used MS412FE (3V 1mah). Very cheap battery (3USD for 6pcs in Aliexpress) Its been 2 days now and i tested to removed the battery and back again.. so far its not changing to default settings. I just look in google how to disassemble the xt20 and luckily its not very hard because no need to peel any rubber. The most difficult is you need to unsolder and solder some wires. Better buy this battery and let some pro do this.. even pc technician can do this

i have the same issue, when changing battery, all my settings back to default. X-t20 user here, no more waranty
