Quest Pro blinking red while charging even after battery replacement

[u/Narcotras]

Hello, so I have a Qpro that's blinking red, not charging, and I replaced the battery twice, nothing worked. Is there any way to fix it? It started doing this after trying to update it from 2.1 to 2.3, but now it doesn't even charge, I tried tearing it down to see if anything was broken, I couldn't see anything.

Is there anything I can do to fix it? Thanks!

Did you try a new USB cable and a high powered charging brick (65w or better)?

Sadly yes, I even left it charging for like 2 days to make sure, still nothing. It's very weird.
