Question

I'm trying to update to a previous stock image (from TRB2_R_00.07.03.2 to TRB2_R_00.07.02.1)

First, I tried via the WebUI but it shows a popup with the following message: 

                                                            INVALID IMAGE

---

                                                                                                                               An unexpected error occurred 

Then I tried using the CLI (with sysupgrade) but it says this:

Mods found: 

FTDI serial chip detected but fw does not support it

This firmware is unsupported by hardware

Image check failed.

Hello,

It seems that your TRB245 contains FTDI chip and older firmwares do not include drivers for it, thus flashing is disallowed.

Could you provide the output CLI command below returns?

• cat /sys/bus/usb/devices/usb1/1-1/1-1.3/idProduct

If it returns 6001, you will not be able to downgrade lower than 7.02.6.

Best regards,
