Deleted my firmware. Help

I updated from version 5.22 (I think) to 6. I then deleted the original firmware from my files section.
Later, I was having some network issues and I did a factory reset on the routerboard (750GL).
It will now not boot. Are there any ways I can load a new firmware on?

Use netinstall

deleting the firmware is not possible. nothing can happen if you delete something from the files section. the system reset caused your issue. your router is now without config. connect with the MAC address from Winbox, and restore the config. I hope you have a backup file.

<3 tyvm, I’ll give it a shot tonight.
