If you still have the browser try this (I believe this was for the KEKA software but it shouldn’t hurt to try):
On your phones browser, enter this link: https://tinyurl.com/adbioapk
It should start a direct download of adbio apk.
Once downloaded, click on the notification (do not go to the file manager) follow the prompt to
allow unknown sources. Once enabled, click the back button (not the end button) and install the
app. Type in the launcher code, open up the app, grant root access, and click enable. USB
debugging is now enabled.
Connect your phone to your pc and open a command window in the platform tools folder. Type
“adb devices” and click “allow” and “ok” on your phone.
Execute these commands:
“adb shell”
“settings put global development_settings_enabled 1”
(This will enable developer options in settings/about phone)
