debrick e750 without replicator

i got a second hand e750c4, and i have no replicator with it.
i have bricked it, by installing updating to latest version of os via web interface. quite sure i chose the right image and device.

anyway, i have tried r8152 connected to its usb type-a port (pine64 usb to ethernet adapter) and other pine64 adapter which comes with pinephone and has usb type-c, hdmi, ethernet, usb type-a on it, this one i connected to usb type-c on e750. i now know it would not work.

but can i connect something if not replicator to usb type-a to upload an image in u-boot mode?

what are my options if i can't find the replicator? i see it's out of stock in the store.

Hello,

That is a customized replicator. If you want to connect to the E750 and access the uboot Web, it requires to connect that replicator.
Uboot only access via the Ethernet.

You can discover if there is this replicator on some second-hand platforms, or try to contact cs@gl-inet.com for inventory status.
