    I was messing with a resolution changer so that my screen could fit on the tv. Out of curiosity, I changed the screen dpi to 100, and my phone started crashing. The screen went black and there was a crash message saying that the System UI has stopped. I tried booting into safe mode, clearing the cache partition and even re-flashing the rom, but the same thing would happen. Is there a way to fix this without losing my data? If anyone could help, I would greatly appreciate it. (Also, does anyone know a custom recovery for this phone? I can't seem to find one)

    My phone is a rooted Galaxy S4 i9506 on 5.0.1.

    You can change the screen density through adb.

    adb shell wm density "dpi"

    I think 480 is the stock value.

    Thanks, I'll check out adb. I hope debugging is still on...

    It is saying that my device is unauthorized:

    List of devices attached
    97cb96e6 unauthorised

    I also get this when I try any command:

    error: device unauthorised
    This server's $ADB_VENDOR_KEYS is not set.
    Try "adb kill-server" if that seems wrong.
    Otherwise check for confirmation dialog on your device.

    The confirmation dialog doesn't appear. I also cannot access the usb debugging settings (or anything else).
