ADB and Fastboot repair tool

Android ADB device detection dashboard

Q: Why is my phone not detected?

The phone must be connected by USB to the same PC or server running the GSMSharing app. Install Android Platform Tools, enable USB debugging, and accept the RSA prompt on the phone.

Q: What does unauthorized mean in ADB?

Unauthorized means ADB can see the phone but the phone has not approved USB debugging. Unlock the phone, reconnect USB, and accept the RSA debugging prompt.

Q: Why does Fastboot not show my Android device?

Use the fastboot command while the phone is in bootloader or fastboot mode. On Windows, install the OEM USB or Android Bootloader Interface driver and try a data-capable USB cable.

Q: Can a website read a visitor phone over USB?

A normal ASP.NET website cannot read a visitor's USB device directly. This dashboard uses server-side ADB, so public users need a local helper app or must run GSMSharing locally.

Find connected Android phones, check ADB or Fastboot state, and fix common USB debugging issues before a flash, unlock, FRP, IMEI, or repair intake workflow.

ADB devices Fastboot devices USB debugging Unauthorized fix

Device service unavailable. Device automation script not found: /var/www/gsmsharing/PythonScripts/android_detector.py

Connection rule: This dashboard cannot read USB devices from a visitor's browser. Plug the phone into the machine where the GSMSharing app, Python, and ADB are running. For a public website, users need a local desktop/helper app before browser-based USB detection will work.

Technician service checklist

Confirm ownership or repair authorization.
Record model, serial, OS version, and state.
Back up user data when the workflow allows it.
Use matched firmware and OEM-approved procedures.

ADB troubleshooting

If state is unauthorized, accept the RSA debugging prompt on the phone.
If state is offline, reconnect USB and restart the ADB server.
If no device appears, confirm the phone is plugged into the app host machine.
If ADB is missing, add platform-tools to PATH or configure DeviceAutomation:ADBExecutable.

Android ADB and Fastboot detection help

Use this dashboard as a pre-check before Android flashing, unlocking, FRP service, IMEI diagnostics, and remote repair sessions. It does not bypass security; it verifies whether the repair workstation can see the device safely.

Why is my phone not detected?

The phone must be plugged into the same PC or server running this GSMSharing app. Install Android Platform Tools, enable USB debugging, and accept the RSA authorization prompt.

What does unauthorized mean?

ADB can see the phone, but the phone has not approved USB debugging. Unlock the phone, reconnect USB, and approve the RSA debugging prompt.

Why does Fastboot not show my device?

Fastboot detection only works while the phone is in bootloader mode. On Windows, install the OEM USB or Android Bootloader Interface driver and use a data-capable cable.

Can public website users connect phones here?

A browser page cannot expose a visitor's USB phone to this ASP.NET server. Public users need a local desktop/helper app, or they must run GSMSharing locally with ADB installed.
