Finally felt like I had to upgrade the companion software on our most-used ROV (it was V 0.15). I linked successfully to the companion and started the upgrade, but it looked like it froze ~ 2hrs later. I refreshed the page, and it said it was at V 0.31, so I rebooted the system and now it seems I can’t connect to the companion at all (neither system or management IPs work), so it seems the update failed somehow. Can I solve this by directly writing onto the microSD? I believe that’s what I did previously since connecting to the uni network via the companion always seems to be difficult.

Hi @Vincent,

Yes, if a Companion update fails you can [fix it by flashing to the SD card](https://www.ardusub.com/quick-start/installing-companion.html).

Note however that [Companion is no longer being developed](https://discuss.bluerobotics.com/t/companion-0-0-31-update-dvl-merge/11143), so assuming you don’t need the Raspberry Pi camera or the Water Linked UGPS (which are not yet supported) we recommend switching to [BlueOS](https://discuss.bluerobotics.com/t/blueos-official-release/12024/) instead 🙂

Great!

Yes I’m sure we’ll upgrade when we get a chance. This particular ROV is getting a huge makeover (inc 4 new thrusters, new frame, new balast) given it’s now 6 years old so it will be the next thing in line!
