first time hear this issue, when and where did you buy it?
It's from tanceline333 in Shopee so it's an ori set but I don't think it matters anyway.
I also searched but didn't see any similar issue.
My best guess was "Google Play Services" is installing in the background (as I saw an update on my HTC U11+ when this happened) and I restarted the phone while it was updating that MIGHT have caused the bootloop.
But if this happened to someone who doesn't know anything about phones, he will surely go to the service center and have it fixed. Think about the hassle it could bring to the customer.
Anyway, I'm quite happy I did wipe/factory because it basically cleaned all unnecessary scripts on my phone and felt relatively faster.
I also noticed Huawei Themes app UI has changed (?) Or is it just a coincidence that they overhauled the theme app?
