Modem Issues with the Pinephone

[Temmie19]

Now part of this was probably my fault, but I'm having some odd issues with the modem.

I got my Pinephone used from a friend, and when I tried to use my SIM card, it could recognize the SIM card was inserted and the towers it could connect to, but it would never be able to connect. So I thought "Okay it's a driver issue" so I went and used the script available at https://github.com/the-modem-distro/pinephone_modem_sdk but I was tired and didn't think to check the current firmware on the modem and that also didn't work. So then I thought to try to load all the old firmwares until it was fully updated, but now the modem still exists and TRIES to function (it'll show me the settings, the lack of bars, and that there's no SIM inserted or that there is inserted) but I can't see it with

Code:

lsusb

or

Code:

adb

and I'm wondering if it's irrecoverable or not?

I did try connecting the two plates on the back of the board to each other, but perhaps that didn't short them out. When I did that, the modem just disappeared and still didn't exist with any command.
