ZOOM G1u Guitar Pedal Firmware 1.20 for Mac OS Description

Firmware version update procedures

1. Before updating the firmware version, disconnect all MIDI and audio devices that are connected to your computer by USB cable. In addition, quit all applications that are running.
2. With the power of the G1u turned OFF, connect the unit with the computer via USB cable while pressing both the DOWN and UP foot switches. This operation puts the G1u into system update standby mode, and “Sv” appears on the display (as in the illustration below) to show that the unit is waiting for a version update.
CAUTION
If the ZFX Tools software that was bundled with the G1u is installed on the computer, ZFX Tools will automatically launch when you connect a G1u to the computer. The unit’s firmware version cannot be updated when this software is running, so quit ZFX Tools before proceeding.
3. Wait a moment after connecting the unit for the computer to recognize the G1u. When it does, “S.v.” appears on the G1u display.
CAUTION
The USB audio driver is necessary to update the firmware version. Follow the wizard to complete its installation.
4. Double-click the “G1uUpdater v1.20.app” icon to execute the firmware version updater application.
5. Confirm that “G1u Ver.*.** [0x********]” is shown in both the MIDI IN and MIDI OUT fields. If it does not appear in one of the fields, click the field and select “G1u Ver.*.** [0x********].”
6. Click the “Execute” button to start the firmware version update
7. When updating the firmware version completes, a notification appears. 
Click the “OK” button followed by the “Exit” button to quit the firmware version updater application. The “ok” message appears on the G1u unit display as shown below. When it does, disconnect the USB cable and turn the power OFF.
8. Finally, after updating the firmware, confirm the version on the G1u itself. 
Updating the G1u firmware version has been finished.

About Device Firmware:

Applying a newer firmware version than the one already installed on your unit can bring various enhancements, include workarounds for diverse problems encountered by the device, and improve or add newly developed features.

On the other hand, downgrading the firmware version can recover the device’s functionality in the event of a software update either turning up faulty or causing the unit’s overall performance to drop. However, bear in mind that applying an older firmware isn’t recommended and might not always be possible.

When it comes to the update steps, due to the large variety of devices and numerous ways for installing a new firmware, it is recommended that you carefully read and understand the upgrade steps, and consider applying a different firmware only when you have familiarized yourself with the update method.

As the installation process is most of the times quite risky, this step should be taken by users that have the ability to successfully complete the update; regular users may initiate it at their own risk. Moreover, it’s best that this task be performed in a steady power environment such as the one ensured by a UPS unit.

Therefore, if you consider applying this release, hit the download button, take into account all the aforementioned aspects, and update the device’s firmware. Also make sure you constantly check with our website to ensure that you don’t miss a single new release. 

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
