I've never ever ran into a situation where holding the power button for ~15 seconds didn't reset the phone. This stuff runs at a _way_ lower level than the software you can mess with. Non-removable batteries are still stupid though.

I have seen newer 1+ phones lock up and it fail to respond to the reset sequence. After receiving a call the modem crashes and it reboots. No other input can reset the device.

  Interesting. Never heard of this.

I recently managed to "hard-brick" my Motorola one 5g ace after updating magisk, getting stuck in a bootloop, and naively deciding to attempt to boot from the B slot instead. On qualcomm-based devices you can get into EDL (Emergency DownLoad) mode where you have nothing that is actually bootable on the device, and the phone will remain entirely unresponsive save for appearing as a serial device when plugged in over USB. You then need to "talk" to the phone with the appropriate protocol (Sahara or Firehose depending on the age of the device) and you can gradually work towards recovery. In my case I was able to manually reconstruct a valid bootloader.img for my particular software version, re-flash it, and get back into a "soft-brick" state from there. However, I do know of some slightly older HTC devices that would have the EEPROM straight-up completely die, leaving the device permanently trapped in a "hard-brick" state unless someone felt like doing some BGA soldering. Modern phones do have a lot of stuff running under the hood that makes it a lot harder to mess things up, but once you go off the beaten path things become much less certain.

  Funny, I've gotten close to doing the exact same thing, though I realized my mistake before ruining it completely. Reset sequence worked the whole time (I think it would even in EDL mode, though you wouldn't _see_ anything). You can definitely mess it up really bad, but I don't know if you can get to a point where there's no reset path. Correct me if I'm wrong though.
