More complicated instructions in Chinese, really feel like ifixit needs to put a warning at the top of this tutorial...

What I tried was following all the steps outlined by the other person, while it seems to work at first the phone refuses to boot after the flashlight is plugged back in and the metal cover plate is installed on top of the motherboard.

Yeah I tried and just gave up, old battery still works fine with about 2/3 capacity so I popped it back in. I highly suspect that with the new HarmonyOS the trick they posted about in 2021 is patched. This is a known issue, I guess it's time to change brands for the next phone oh well.
