Hi,
I am a fairly new user of GrapheneOS, I have had the OS installed on my Pixel 7 for over a month and it has been working perfectly.
Yesterday, I tried plugging an external SSD to my phone to see if it could read from it and as soon as I did that I got the "Your device is corrupt" red error screen. I can press continue and then it goes to the default boot sequence of my phone that warns me about a new OS installed different from the stock and it boots fine.
Despite this red error when I boot or power off, the device works fine. The only issue I have noticed is that NFC stopped working for one app but it works for other things so I don't think this is related to that.
I know similar questions have been posted before but since in my case it happened after plugging an external drive to my phone while it was on, I figured I should mention that. How should I proceed then?
Should I try reflashing GrapehenOS to my phone? And, then, before I do that, can I easily backup all of my profiles, app and stored data to an external storage and restore everything after successfully reflashing?
Thanks in advance!
