How to upgrade bootloader on rb1000!

I lost my rb1000 by putting 4.14 on it.
Now it doesn’t matter which package I put on, every reboot resets router back to default…

Another topic tells me I need to update my bootloader. But how?

Can anybody help me out here?

Thanks Fewi, I forgot that that was the bootloader.

I didn’t tell you to do it, I asked if you did it. The bootloader was broken in v4.14, that’s why I asked.
