What is GSD Dongle?

GSD Dongle is a hardware-based (USB dongle) GSM repair tool providing multi-brand unlock, FRP bypass, and IMEI repair operations. The dongle acts as a physical license key — the software runs on your PC but requires the dongle to be plugged in for operation.

Hardware Dongle vs Software License

GSD uses the traditional hardware dongle model common in the GSM industry:

Dongle: USB device containing a security chip that stores your license. Software checks for dongle presence before allowing operations. Cannot be shared or transferred without physical dongle
Advantages: No internet required for license verification (works offline). One-time purchase (usually no subscription). Resale value — can sell the dongle when not needed
Disadvantages: Physical device can be lost/damaged. Must be connected during use. Shipping cost and time

Functions

Function	Detail
Network Unlock	Multi-brand carrier lock removal via direct patching or code calculation

How to Set Up GSD Dongle: Step-by-Step

Purchase GSD Dongle activation/renewal from Code-GSM
Plug the GSD Dongle into your PC's USB port
Install drivers: Allow Windows to install the dongle driver. If not detected, install manually from the included CD/download
Download and install the GSD Software suite from the official website
Launch the software — it reads the dongle's serial automatically
Connect the target phone via a second USB port
Select brand and model from the software interface
Choose operation and execute

Hardware Dongle Tips

Dongle must stay plugged in during all operations — removing it stops the software
Use a direct USB port on the PC — USB hubs may cause detection issues for both dongle and phone
If the dongle is not detected, check Device Manager for driver issues (yellow exclamation mark)
Activations purchased from Code-GSM are applied to your dongle's unique serial number
Some GSD activations are lifetime, others are timed (yearly renewal) — check the product description

Troubleshooting GSD Dongle

Problem	Cause	Solution
Dongle not detected by software	Driver not installed, USB hub issue, or dongle hardware fault	Install dongle drivers manually from Device Manager or official download. Plug directly into PC USB (not hub). Check Device Manager — dongle should appear as "GSD" USB device or COM port. Try a different USB port
"Activation expired" message	Time-limited activation (yearly) has expired	Purchase activation renewal from Code-GSM. The dongle continues to work for already-supported operations after expiry, but no new device support until renewed
Operations fail while dongle is plugged in	Dongle USB driver conflict, or another device using the same driver/COM port	Close all other serial/COM port applications. Reinstall GSD software freshly. Ensure no COM port conflicts in Device Manager (Advanced Settings → Port → COM Port Number assignment)

Frequently Asked Questions — GSD Dongle

Q: Can I use GSD on multiple PCs?
A: Yes — hardware dongles are not tied to a PC. Plug the GSD dongle into any PC, install the software and drivers, and it works. The license is in the dongle hardware, not the PC.

Q: What if my GSD dongle is lost or damaged?
A: Since the license is stored on the hardware chip, a lost or physically damaged dongle means the license is lost. There is typically no digital backup or transfer mechanism for hardware dongles. Keep the device safe and insured if the activation value is significant.

Q: How do I know which activation tier to purchase for GSD?
A: GSD activations are often sold by brand module (Samsung + LG + Huawei etc.) or as a combination. At Code-GSM, check the service description for which brands/chipsets each tier covers. If you primarily work on Samsung: purchase the Samsung-specific activation. If multi-brand: purchase the full activation bundle.
