Where is the reset on the Groove 52 AC then? It's not like on the original groove nor like the Hap AC. There are no images anywhere showing it especially not in the wiki.Try to hard reset the device by shorting special hole of board . After that try netinstall or try after few of days.
I have several boards / mipsbe based / groove, 951 series with same issue... for me this issue comming from bad flash memory and only full format/netinstall/ may solve the problem .
Thanks, but no, the Groove AC is very different in terms of the board, hence my post above. I don't think there is anything online about resetting the Groove AC manually. I think it needs a Mikrotik representative to tell people how, as it seems different from all the others I've seen.How disassemble and use the reset:
Hope yours is the same.
It's similar. But not the same. In the video you can see by the base of the board there are two holes with contacts around. The guy in the video uses a screw driver on the left contact to reset the board. On the AC board there are no holes, only one contact and sticking a screw driver on it achieves nothing at all. In the video you can clearly see the contact the guy uses to reset the board is split into two parts. He jumps those two part with the screwdriver. On the AC board, this doesn't exist.I think the board is the same like nonAC Groove with different cpu and ethernet port !
