[Miscellaneous Android Development] lil123:
Thank you for this guide.

And a Happy New Year :o

I am new to smartphone customizations but somebody gives me a CAT S60 and I want to enjoy it without google apps impossible to disable or uninstall...

And maybe enable dual sim ?

So I tried this guide to root my smartphone and become the real boss ;)

I followed the steps but something goes wrong when trying to download twrp on the phone.

adb usb
* daemon not runnint. starting it now on port 5037 *
* daemon started successfully *
error: no devices/emulators found

adb usb
error: no devices emulators found

adb devices
List of devices attached

But it does not work. Here is the QFIL log :

What is wrong ?

I hope you can help me to solve that and proceed to next steps.

Thank you !
