@Dresa91 Where's the (official) rollback ROM:
support softwareupgrade - OnePlus (United States)?
I chatted with support, and they also said there was no "official rollback ROM", that they could point me to.
This thing is a friggin' mess. My data is up for a couple of seconds, at a time, and then down, so pretty much ALL things secure (authenticator apps, SMS, etc), fail to work, citing the "lack of mobile-data connection", which is required, by most.
I can't find the method to flush the System-Cache, on A12, it just doesn't seem to exist? I suspect this would help (or at least not hurt) with some of the "network randomness". I've done several "Network Resets".
I'd prefer not to reset my entire device, at this point, given that my last backup was on A11, which is clearly going to be an issue, with restore, if I do a reset (and yeah, I don't want to overwrite my backup, with an A12 backup, it's disabled for that reason, for now).
I had T-Mobile re-provision me (it's NOT a TMo device, it's a IN2025 direct-purchase 9 Pro), and they said it looked like the phone was constantly resetting the mobile connection, over-and-over...
To anyone wanting to upgrade, I would suggest WAITING, until this whole mess is sorted. I guess I should've done some searching, when I got that popup-notification yesterday evening, to upgrade. I wouldn't wish this build on anyone...
