I had a failure with a U6+ earlier this year, totally unresponsive, gibberish on the UART. The U6+ APs apparently used an often defective eMMC module. Apparently, the issue was an incredibly low tolerance for writes! Even tho’ mine was out of warranty they made an exception & replaced it. I’ve two U6+ in a customer install, need to check them but I reflashed them with OpenWrt.
Nov 5, 2026, 12:09 AM@guardeddon @imrehg I called LinITX who I bought it from, explained the situation. They were impeccably helpful but ultimately said, no sorry, it's out of warranty.
My only real recourse would be via them as the supplier, and they've effectively closed that door.
So I've got a bricked device going to e-waste.
Again, this makes me not want to ever buy UBNT shit again. Despite being something of an evangelist for them in the past.

I went direct to UBNT’s support site.
I had acquired the particular unit in a non-operating state & expected to resurrect it by re-flashing OpenWrt via the UART & first stage bootloader. I’d opened the shell to access the UART port pads. Surprisingly, without much persuasion, they agreed to replace as a special RMA case. I’d found many posts, across various fora, describing the eMMC storage problem.

Nov 5, 2026, 7:46 AM@guardeddon @imrehg I sent a follow up email to linitx last night as I am pretty sure they hadn’t seen all the forum posts when we spoke on the phone
Nov 5, 2026, 7:48 AM@guardeddon @imrehg let’s see what linitx say. TBH I won’t hold it against them if they say not possible / it’s legit out of warranty and this is a UBNT fault really
