Was someone able to flash openwrt to a nanobeam ac gen2?
I just found in the forum this thread.
I would like to try the normal nanobeam ac image, but then I have to open the device. How can I open the device?
I bought one and had OpenWrt working, but the device hardware failed (I think the switch chip) so I can't run it now.
The install can be made without serial, using SSH. And TFTP recovery using the reset button can recover from almost any bricking.
If you have to open, which is a last resort, they are glued shut and have to be cut open around the edge seam. This will be destructive. Use a thin hand saw blade to cut a little gap at the bottom then start prying carefully-- the seam should crack mostly at the glue. I also opened up and repaired an old Nanobeam M5 and was reasonably successful putting it back together with Gorilla Glue Clear.

Could u give me a link? I thought I have to get a specific firmware, that is not available for my Gen2? 
That would be awesome if I could try flashing OpenWrt without the need to open the device.
I was definitely running some sort of release build. I would have to put it back together enough to power it up to find out which one. Maybe tomorrow.
Flashing process should be very similar or identical to the AC loco etc-- install a specific version of OEM firmware, ssh in and patch the fwupdate binary so it will not check the signature, then use that hacked binary to flash OpenWrt.

Yep. But I have the WA with 2 Ethernet Ports but there is v8.5.0 firmware only for the XC Board. I will just try flashing the XC firmware.
I found the correct firmware but it says
Incorrect firmware version. Please upload v8.5.3 or newer and try again.
Shit. 
Edit: Hmm, I will try tftp recovery...
What about extracing with binwalk the necesary ubntbox from the 8.5.0 image. Copy it to the nanobeam and then do the symlin and then flash it? Could that break the tftpboot recovery?
I tried flashing with the Lite-Beam-Instructions.
I can not reach it anymore. Maybe the ethernetport is somehow different in the ac gen 2? I would love to have an serial port. 
(I can still recover with tftp)
On the openwrt common ubnt-page is a working example with working firmware. 
But switch is still dead.
Flashing the latest stable does not work.
Only master works.
WA# chmod +x /tmp/fwupdate.real
WA# /tmp/fwupdate.real -m /tmp/openwrt-19.07.3-ath79-generic-ubnt_nanobeam-ac-sq
uashfs-factory.bin
Invalid version 'WA.ar934x.v8.5.0-42.OpenWrt-r11063-85e04e9f46'
Ì modified nel/mac80211/files/lib/wifi/mac80211.sh that the ssid is not disabled automatically and flashed an image.
Here is the bootlog with latest openwrt master:

@mk24 I used the whole day to get a PR working for the ac gen2. It would be nice if you could test.
Got the hardware out again and hooked up serial. It was flashed with 19.07.2 for Nanobeam AC, which as you noted does not work. The switch chip (AR8334) is not detected, and no data can flow from the Ethernet ports. I know that at some point I had it running OpenWrt with Ethernet and everything-- this would have been before 19.07 so it must have been a snapshot build. Then I must have upgraded it to an incompatible version and confused that with hardware failure. Which seemed unusual at the time since it would be the first Ubiquiti hardware I've had fail that hadn't been struck by lightning.
Today I determined clearly the Ethernet is OK since the bootloader can answer pings and TFTP files.
The hardware is actually very similar to the Nanostation AC. It looks to be the same set of chips with a different antenna. So I booted up the 19.07.3 initramfs image for Nanostation AC, and Ethernet works with OpenWrt. I'm still testing that image. It looks like there are two wifi radios and an Ethernet switch like there should be.
So executive summary is: Use Nanostation AC builds on the Nanobeam AC Gen2. Maybe.
The design of kmod-ath10k-ct allocates a lot of RAM in favor of performance. The smallbuffers version is essential on a box with 64M and a good idea with 128M. The regular version will take up all of the RAM and crash these routers.
I noticed that, too. So I took the ethernet part dts stuff from nanostation ac. And it worked!
I already switched to smallbuffers, but I forgot to push it. ^^
I've been running the release 19.07.3 Nanostation AC build on mine and it seems to work fine. Not sure if a separate model is necessary. Ubiquiti has tried to build groups of models around shared hardware platforms, though their naming scheme isn't always clear which one is inside your box.
The wiki pages on these need a lot of work. According to them there are two versions of the Nanobeam AC Gen2: one has a single Ethernet port and the other one (which I have) has two. Is yours also with two ports?
Yep.
Does your 2 wifi radios work? Could u post a dmesg or logread output?
I still have issues with jffs2. Here is a gist after flashing.
Here is the gist after a reboot
Yes both radios work. Realize that though the 2.4 radio is fully supported in software, its hardware has only a single tiny antenna so it is only suitable for close range.
I'm not seeing any problems with the jffs like you were. It looks like the flash chip is readable, but not responding to erase or write requests.
Did u try 5.4 kernel? Since that is the problematic kernel version for me.
I added a bug report: https://bugs.openwrt.org/index.php?do=details&task_id=3272
I can confirm that the 5.4 build of today's snapshot for Nanostation AC does not work on my Nanobeam AC Gen 2. The same failure to erase / write to the flash occurs. 19.07.3 ath79 builds work properly.
What isn't clear is whether this build would also crash on a Nanostation AC, or is there a real difference between the Nanobeam AC Gen2 and Nanostation AC. I don't have a Nanostation AC to test on.
