It used to try IPv6 but I've disabled it in some config. It worked for one time, but the next session it stopped (but it still connects via IPv4) Btw going to debian.map.fastlydns.net from a browser (as if it was a website) returns "unkown domain", while pinging it works. This seems weird.

Absolutely same, but I've been switching from Opera. I was kind-of veteran Firefox user but my primary browser for many years was Opera. By 2025, Firefox became slow and bloated as hell, even it's visual design (on mobile at least). I've tried a couple of forks, but they were either slow or ugly in my opinion. But Waterfox was not slow and it's look is exactly what I need: modern but not bloated. So I switched immediately.

I tried Librewolf too, and I just disliked the design, and it was also very slow for no reason.

Update: I've abandoned rescuing the USB and just flashed another iso with balenaetcher, and it booted normally. According to my previous experience, the USB will be fine once formatted from this state. But I would still like to know how to rescue dead USBs like in my case. So, don't use ventoy unless you really understand what you are doing.

I couldn't make a post without a picture for some reason so I've attached random pic Anyway, thanks for advice, I will give Graphene a try if I manage to get a Pixel

I wish I could use Graphene but I'm afraid I won't manage rooting a Honor

Once I tried rooting an old ZTE and even then I failed

I'm not sim-swapping at all, but I have recently placed my phone into faraday cage, maybe that was the trigger?

Carrier-locked phones are not common in my region. Maybe it's Huawei's tricks?
