Little update broke the OS

Ok it’s a sad story.
I got a Firebox II because I like trying old hardwares, it will not work well even on m0n0wall, but when I try routerOS it really make me shock, high throughput and tons of features with little hardware use.
So I buy a L4 license just an hour ago, even the timer seems stuck at 19h xxm (lol I don’t know why but it showed that forever), after activate I update it from 6.32.2 to 6.32.3 use winbox, now it refuse to boot…
The hardware is very old and it often stuck at bios, I have to power cycle until it boots even on other OS, but if it shows LAN1 and 3 LED means it’s already in boot. This time, it won’t finish the start no matter how hard I try, I believe the stuck is at routerOS itself, because the LED shows up to indicate the BIOS is not stuck.
There’s no serial output before “mikrotik login”, so I get nothing now, oh and no VGA port on that, so I cannot debug the booting process.
That’s all, I don’t think I can rescue it, maybe only try another OS later.

You can try netinstalling it if it has removable storage.

I’d stay on bugfix version, 6.30.4

Cannot you get to its BIOS via its console? If its storage isn’t removable you could try netinstalling it (bootp)…

Hi.
Yes it have a removable DOM with 44pin IDE, I installed the OS by connect it to a USB-IDE convertor and then mount it as a device in VBOX.
No I cannot get BioS by console.
I did a “check install” before it fail, and no errors.
Can I just use USB / VBOX to install again? Will I lost the license?
Thank you.

Yes you can use that USB adapter to reinstall the DOM.

Download netinstall http://download2.mikrotik.com/routeros/6.30.4/netinstall-6.30.4.zip to a windows PC or VBOX image.

Do the same with ROS 6.30.4 x86 (http://download2.mikrotik.com/routeros/6.30.4/routeros-x86-6.30.4.npk

Start netinstall, look at its lower pane (Packages), click on browse and point netinstall to the ROS .npk file folder.

Plug the DOM to that PC, and note its drive letter.

netinstall should show it in its upper pane (Routers/Drives) select the drive letter, tick the ROS file you downloaded in the lower pane, and click on install button.

Netinstall should recognize the old license, and install it; if it doesn’t, as soon as you access the Firebox with winbox, open a New terminal and paste the license text block you received directly onto it and check (system > license).

As long as its the same DOM drive you shouldn’t have problems activating the license, but the filesystem could have became corrupted or changed significantly preventing the license from activating.

Thank you very much for the detail instruction, I’ll try it later.
