Cinterion ELS61T-E2 flashing orange on startup

Hi.

I just got this device. I am pretty new at this, so please bear over with me.
I started up the device and everything was working fine. Had a few issues, so decided to upgrade the firmware, so I downloaded the OpenWRT 19.07.2 firmware for the Atheros AR9330 rev 1. I upgraded from 18.06.2.

The upgrade itself went fine, but it would not recognise the WWAN interface, so I had no connection to the GSM network. I tried to create a new interface. This is where the real problem started. I lost connection to the device.
When I try to boot up the device now, the orange light is flashing. It keeps doing that eternaly. I have tried to connect a RS232 cable to the device and do a PUTTY on the COM port at speed 115200. When the device turns on I get the following:

^SYSLOADING

 ^SYSSTART

Nothing happens after this. So what do I do now? Can I factory reset the device? I should probably downgrade to its original firmware as well. Any ideas would be happily appreciated.
Thank you in advance
