Netinstall won't start after finding PXE client [SOLVED]

Thu Oct 14, 2021 1:04 pm

Hello, I'm trying to netinstall a bricked RB4011 using netinstall for Linux (Ubuntu 20.04 VM under VMware Fusion).
mkdir netinstall && cd netinstall
tar -zxvf netinstall-7.1rc4.tar.gz
sudo ./netinstall -a 192.168.XX.YY routeros-7.1rc4-arm.npk
Using server IP: 192.168.XX.ZZ
Starting PXE server
Waiting for RouterBOARD...
...but then nothing happens, no "Sending image". The same PXE client appears then several times. I am currently using DHCP instead of BOOTP. I'm using a console cable to verify the process in the other side. I can access setup. Should I format NAND or use any of the available options in RouterBOOT? Thank you.

EDIT: Some thoughts about netinstall for Linux CLI:
  • It doesn't work on macOS Intel 64 bit:
    cannot execute binary file
    exec format error
  • It doesn't work on neither Raspberry Pi Ubuntu ARM64 nor Raspbian ARM (32 bit):
    Syntax error: "(" unexpected
  • It works on Ubuntu x64
EDIT2: Solved blockage after switching to BOOTP, but then I got:
Sending image: arm
Discovered RouterBOARD...

On the RB4011 side I get some mac info along with the key:

EDIT3: What is the "-a" parameter for? Is it important? I just put an available IP address in my subnet, but some people put

EDIT4: SOLVED!!! Based on this thread: viewtopic.php?p=885791
  • Access bricked RB4011 via serial (Cisco) cable.
  • Enter setup, select boot device:
    e - boot over Ethernet
  • Start netinstall from Linux x86 using old version (6.47.9). Wait for error to appear
    Key was rejected
  • Start again netinstall from Windows using latest version (7.1RC4).
  • Success!
The problem was that Linux recognizes the router but won't flash it. Windows on the other hand would not recognize the router (but it would flash it once recognized).
