u/Hrublko_OFF

Today my "new" BlackBerry 9720 arrived. I charged it for a bit, then I did the secure wipe. While it was wiping itself, on the white screen it suddenly showed the red cross battery screen. Because of that I took out the battery, put it back in, and it has been on the red cross battery screen ever since.
Now it starts booting with the BB logo and the progress bar, but right at the start after making a bit of progress it goes to the red cross battery screen. I did somehow manage to kinda flash an updated OS on it from BBViet, it went back to the red cross battery screen during a "JVM" thing, and that's where the update failed. Sometimes the keyboard flashed on boot.
Feel free to ask anything, I want to fix this BlackBerry. Right now it's on the charger.
EDIT: also there was a solid green light sometimes between boots? the screen was off iirc (or black)

I have a OnePlus Nord (on OxygenOS 12.1). When I change the DPI (either in developer settings, with adb shell wm density 320, or with the Pixels app), after a restart and (a few seconds), it resets to the one set in display size settings (which in my case turned out to be 382 DPI).
Is there a way to keep a custom DPI forever (without root)?

The Titan 2 Elite/Pro, but with a taller 16:10 or 16:9 screen (and possibly larger battery), something like the BlackBerry Key series.

This is a quick mock-up that I made in gimp, so the screen doesnt have a standard aspect ratio.

After replacing the battery, when charging with the Warp charger, it turns off when it hits (probably) 100%.
With a non-Warp charger it charges to 100% fine without turning off and it stays on for the whole duration that it's plugged in (e.g. overnight).
