Help with iomega ix4-200d installation (no replies)

Hello, maybe this is the dumbest question on the whole thread, im merelly an advanced user not a dev or linux guru by any means, so i got stuck on this one, i have an iomega ix4-200d and im trying to extend the life of it by installing debian and omv on top of it, the thing is that my soldering skills are pathetic so i want to avoid to solder a serial header, for that i need the device to have ssh opened since the first boot but maybe im doing something wrong or the service is simply disabled by default but i cant connect to it, i used the 25 Aug 2019 procedure to create the usb, to avoid complications i formatted it as ext3 to skip the fstab step and at first i tried without embedding the dtb and the device turns on, works for about a minute then stays with the batt and eth icons on the mini screen, eth ports blink, i can ping the box but ssh gives me connection refused...so i tried the same embedding the dtb, same result...

TLDR: how can i enable ssh without a serial console using your rootfs on an iomega ix4-200d (maybe editing some files on a debian pc i have at hand?)

Thanks in advance for any help you can provide
