fbpng v1.0 - I made a simple png file displayer that directly writes images to framebuffer. Apparently it was more complicated than i thought. Of course written in C.

usage: ./fbpng <img.png>

Does something feel off? (lmao)
Naah bro something's off fr

I learned how to hook SystemUI process and snipe out a specific TextView and modify it as I like! What a great utility Frida is!

Changing battery text from command line by attaching SystemUI process with Frida (Preview here)

Java.perform(function() {
  const T = 'com.android.systemui.statusbar.phone.SwitchableDoubleShadowTextView';
  const I = 0x7f0a014c;

  Java.choose(T, {
    onMatch: function(tv) {
      if (tv.getId() === I) {
        Java.scheduleOnMainThread(function() {
          console.log("changing");
          tv.setText(Java.use('java.lang.String').$new("hi"));
        });
      }
    },
    onComplete: function() {}
  });
});

sudo frida -D local -l file.js -n "com.android.systemui"

Using a WIFI USB OTG adapter as main WIFI source in my Galaxy A14 (Rooted, ARM64 Android 14)

Basically we rename wlan0 (main WIFI) to wlan0_old, and then we rename wlan1 (USB adapter) to wlan0

# make sure adapter is connected
svc wifi disable
ip link set wlan0 name wlan0_old
ip link set wlan0_old down
ip link set wlan1 name wlan0
ip link set wlan1 up # if DOWN
svc wifi enable

Now, since the OS might not be able to use the adapter to list netwroks, we need to connect manually

# use -h if network is hidden
# see cmd wifi help for more
SSID="SSID"
PASS="PASS"
cmd wifi add-network "${SSID}" wpa2 "${PASS}" -r persistent
cmd wifi connect-network "${SSID}" wpa2 "${PASS}" -r persistent

And then the wifi should appear in status bar

Now to restore wlan0 as main wifi

# disconnect adapter before this
svc wifi disable
ip link set wlan0_old name wlan0
ip link set wlan0 up
svc wifi enable

To fix this error from android shell
resetprop persist.sys.rescue_level 0
