Customer's Question

- Can we upgrade version 1 firmware to version 2 firmware to use with BioStar2 SW?

- Can we downgrade version 2 firmware to version 1 firmware to use with BioStar1 SW?


- Answer is "Yes", but it depends on the firmware and the device type. 

- Refer the explanation below.

This article is for Suprema Authorized Distributor and Suprema Sales team only.


The line of 1st generation entry level devices are as follows: Xpass, Xpass 2, BioEntry Plus, Bioentry W, BioLiteNet

These devices (with the latest hardware version) are supported in both BioStar 1 and BioStar 2, but not with the same firmware.

1.x firmware is supported in BioStar 1 and 2.x firmware supports BioStar 2. 

Hence if you have a 2.x firmware device the device will not be searched in BioStar 1 and if you have a 1.x firmware the device will not be searched in BioStar 2. 

The special entry upgrade tool to downgrade and upgrade the firmware to 1x <> 2.x is provided to our local partners.
If you are a end user, contact your distributor for the firmware upgrade. 

We do not provide the tool to end users because a misuse of the tool can lead to device malfunction.
When the device malfunctions there is no easy repair option and will require a RMA processing to fix the device. 

Note: for BioLiteNet, BioEntry W and BioEntry Plus, only devices with OC-4 sensors can be upgraded.

This includes devices where you only replaced the OC-2 sensors with OC-4 sensor.

To convert for each firmware, you should use Entryupgrade software. 

Before considering the upgrade progress, please make sure your environment allows the following configuration. 

If not, your device will malfunction in the upgrade process and you will have to process the device through RMA. 

Before upgrading a site from BioStar 1 to BioStar 2, please refer to the feature limitations of entry devices in BioStar 2:
[Announcement] Notification About Feature Limitations with 1st Generation Entry Devices


1) UDP 

- Confirm that the PC with the Entryupgrade tool installed is available to detect a device via UDP. UDP is required for the upgrade retry process when there is upgrade failure. 

* If your PC has multiple network cards, turn other network cards off except for the one that will search the device. 


2) Internet

- Confirm if the PC is available to access Internet. The Entryupgrade tool checks the license of Entryupgrade tool though Internet access.


3) DHCP server

- Confirm if the customer has DHCP server or DHCP router to assign a dynamic IP address to a device.

- If not, there will be upgrade failure during firmware upgrade.
