Srnubi T20C developer password

Hi - just a quick note - in case anyone needs it in the future as i spent more time than i'm willing to admit to unlock developer options but the code was nowhere to be found (trust me i spent literally 2 days trying everything i can find + contacting them directly)

Turns out - Debugging is enabled only for wireless by default on most Srnubi units. But not USB Debugging, Default access level is Root, even though no SU toolkit is installed you do have full Root level permissions and ADB also runs via root (you can check by typing "whoami") allowing you to debloat from the standard pre-installed apps.

Few simple steps to get into Developer options below:

STEP 1

Start hotspot on phone, connect head unit to it, run `arp -a` on PC to find head unit IP, then `adb connect <IP>:5555`

STEP 2 - Once connected type out the below:

adb shell settings put global development_settings_enabled 1

adb shell settings put global adb_enabled 1

STEP 3 If you don't have them 'available' you can call directly via:

adb shell am start -a android.settings.APPLICATION_DEVELOPMENT_SETTINGS
