KNX DALI-Gateway Basic REG-K - Firmware update

[PiotrJakubczyk]

I'm reading "Special Instructions for Update from 0.2.x to 0.3.x and downgrade" provided with 

"MTN6725-0004 DALI-Gateway Basic REG-K Firmware 0.3.5 for ETS Application 7313 (0.3.5)" 

https://www.se.com/il/en/product/MTN6725-0004/knx-daligateway-basic-regk-2-16-64/

Special Instructions for Update from 0.2.x to 0.3.x and downgrade
Please note that with firmware 0.3.0 an extensive expansion of the device's function has been carried out. This firmware re-quires the ETS applications 7312/1.1 for MTN6725-0003 and 7313/1.1 for MTN6725-0004 and the corresponding DCA SpaceLogic KNX DALI Gateway Basic Plus V1.1.2.0. Commissioning with the old application and old DCA is not possible. If a device with firmware 0.3.x is to be loaded with the old application (e.g. when replacing a device or expanding an existing installation), it must first be downgraded to 0.2.7. A special downgrade file is available for this purpose: "Firmware 0.2.7 Downgrade". When downgrading, any existing data in the unit will be deleted (physical address, etc.).
When updating from version 0.2.x to 0.3.0, all data is also deleted. The device must then be reloaded with the ETS and the DALI data must be restored with the restore function in the DCA (see also the description of the application program). Please note that the unit is initially loaded with firmware 0.3.0 or 0.3.1. Firmware versions higher than 0.3.1 must not be loaded directly into units with 0.2.x, as these are not "Unconditional". In this case, the update must be carried out in two steps. First to 0.3.1, then in a second step to e.g. version 0.3.2.

There are references to "Firmware 0.2.7 Downgrade" but no such firmware provided in pack. Is this instruction is obsolete? What i should do with "MTN6725-0004_Firmware_Upgrade_to_V0_3_0" and what "MTN6725-0004_Firmware_Update_0_3_5.zip"

I should replace "Firmware 0.2.7 Downgrade" with "MTN6725-0004_Firmware_Upgrade_to_V0_3_0" ?

"Please note that with firmware 0.3.0 an extensive expansion of the device's function has been carried out" Noted this on front of device with black marker but still don't know how to upgrade 🤔. Someone can translate from R&D to English? 😁

Hello Piotr!

It says that you should be carefull with the update in the way that it requires a new ETS-Applicaton with the dedicated DCA.

Means => In case you have an existing ETS configured running device and you want to perform this update (because you are interested in the new features) ...
You need to use a different (new) DCA and ETS-Application as you used before.
