This message appears after I run the cmd file

2024-07-01 16:33:39.749 ERROR Main: Cannot start client: Command adb ["shell", "am", "start", "-a", "com.genymobile.gnirehtet.START", "-n", "com.genymobile.gnirehtet/.GnirehtetActivity"] returned with value 255

I don't know why this message appears on this particular phone and does not make a call, but the same method works with other devices.

@Abdelrahman232323 please add missing information:

System Info:

• Desktop: OS & Version.
• Android Version.
• Mobile Vendor & Device Model.

Issue Info:

• Command(s) that led to this error.
• Does it always happen?

Do any of the following steps fix the issue?

• restarting the Mobile Device
• physically reconnecting the Device
• restarting gnirehtet on Desktop
• restarting gnirehtet on Mobile
• wipe the cache partition of the Android Device (there's lots of guides on the web ~ sadly some Devices don't let you do that ~ samsung devices all have this feature, for example)

This looks like either misconfiguration, missing permissions or a bug in some part of the system.
If you did not mess with sensible settings of your device or installed software that causes that behaviour, it might be an issue related to the System ROM (in other words: the manufacturer messed something up).

Always make sure your systems are up-to-date and the application you're reporting about has the neccessary permissions.
