Hello.
Today I received my mikrotik chateau 5G, and when i try to update it after reboot it will not boot.
So I made a reset After reboot i goot a boot loop So I tried with netinstall, and I have a problem - but I cannot install the firmware - it shows purple led
I tried to install different versions of firmware, but with no luck.
Can you help me?

I fix few boot-loop units... with NetInstall and Wireshark, check my HowTo viewtopic.php?f=2&t=167360&p=821518#p821518
Remember that some version of NetInstall.exe not work properly and try use other, e.g. viewtopic.php?f=2&t=176162

I have the same issue and the linked tips won't work for me.
Did you ever fix this unit?

In my case I can see with wireshark:
- bootp request from chateau 5g and reply from my machine (client ip is assigned)
- tftp transfer for file vmlinux: - tftp transfer completes after block 2390 and machine seems to send bootp reply again:

During that time the power / system led is blue.
~10 seconds after the transfer (last) completes, all leds turn constant green for about a second except system/power led is purple
- a few seconds later the process starts again

I'm stuck in this loop.

I tried various machines (even an old windows xp), switches in between, etc.
Can anyone test with a "working" chateau 5g if it boots netinstall at all?

The same problem. A few days ago I tried to update ROS to latest version on client's Chateau 5G, router rebooted and no more booted.
How to properly do netinstall for this router ?
I tried to connect laptop with netinstall to Ethernet 1 port, pressed and held reset button and then powered on the router, but with no luck. Netinstall doesn't see the router.

A few others have exactly the same issues: https://www.reddit.com/r/mikrotik/comme ... boot_loop/

Mate I have exactly the same problem after attempted upgrade 7.11.2

Try Netinstall 7.12beta3 Testing.
Check both regular and backup booters https://help.mikrotik.com/docs/display/ ... kuploaders

do you know this is an issue with netinstall - no mention of anything in the changelogs ?
Have you tried this ??

UPDATE:[SOLVED]
using Ubuntu Linux fresh install with netinstall-cli (7.12.beta3) and routeros 7.12.beta3 works.
Thanks for the suggestion

Confirm, I could repair my Chateau 5G using windows netinstall 7.12beta3 !

Hi.

I have a same problem, i tried run wireshark but the only display is boot request from ( mac address of chateau 5g ) any one help me?

@chanchan

Use Netinstall 7.12.x and reinstall.

Then I found another issue that causes the unit not to boot sometimes, I set the CPU frequency from auto to lowest and never a problem.

@themenace

Thank you. Its now working on the netinstall.
