recovery RB450G

Hi! I have a RB450G which had 3.22 andI tried to upgrade it, from 3 to 4, 4 to 5 worked find.
On 5 I still had the old upgrade page open which actually was still accessable and triggered the upgrade.
After that the device went into a boot loop.

I tried to the Netinstall v6.42.3 on a windows 7 computer I had lying around, but I did not succeed.
I could see that port 67 was open and I could see on wireshark was seeing bootp requests from the router,
but I could not see the device popping up in the netinstall. I tried disabling all other interfaces, add a firewall rule
for the application, fully disable the firewall, closed all other applications, rebooted the machine, ran the
Netinstall as administrator, … and sure the the 192.168.88.2 was statically configured and 192.168.88.3 was
set up as the cilent ip but I never succeeded.
I would assume its still something on the old windows machine, so if possible I would not like to use it.

As I am mainly working with Linux/Mac os, are there any other options? I tried to set up my own bootp+tftp server
pointing to the routeros-mipsbe-6.42.3.npk image. I see the file gets transferred but then it also just restarts,
but at least I get a file transfered, so if one has some inside on how to set it up?

TFTP is only for netboot. NPK files are not bootable images, they are for installation only, therefore trying to feed the bootloader a NPK file via TFTP is not going to do you any good.

The bootable image used for Netinstall is built into the Netinstall application, and is no good by itself…it has to be used with Netinstall (once the router boots the Netinstall image, then it communicates with the Netinstall application on the host, which feeds the NPK file of your choice to the Netinstall client running on the router for installation). To recover your router, you will need to get Netinstall working on your computer. If you cannot get it to work on the computer you have been trying to use it with, then I would recommend trying a different Windows computer.

It’s conceivable that Netinstall might work under Wine, if you insist on not using a Windows computer. But Netinstall is a Windows application. You could try running Netinstall on your Mac under Wineskin. I have not tried it myself, but one tip I would give you: I have had difficulty with Winbox under Wineskin when I had more than one network adapter enabled. So if you have trouble getting it to work, then try disabling the Airport/Wi-Fi adapter and make sure that the Ethernet adapter is the ONLY adapter that is enabled. Assign the Ethernet adapter a static IP address, then configure Netinstall to assign an IP to the router that is within the same subnet as the computer’s Ethernet adapter.
