Weird freeze of firmware and cannot save config - Nanobeam AC GEN2

Installing and Using OpenWrt
1

Hi.

I have two Ubiquiti devices (NanoBeam AC GEN2 and LiteBeam AC GEN2), so i rollback first the firmware to WA v8.7.4 of NanoBeam. After a while, i finally installed OpenWRT with image factory.bin of v24.10.0 but... appears 2 problems:

1- If reboot the device, config is not persistent.

2- If try an update, no success and still remain the same version (v24.10.0)

Any suggests? At least for point 1. Thanks! And sorry for my English.

Regards.

Version 24 has a bug which prevents OpenWrt from being able to write anything to flash on these models (most if not all of the Ubiquiti CPEs). Use the latest version 23; early version 23 also had the bug which was fixed once then re-introduced for 24.

Since OpenWrt cannot write anything to flash including new firmware, and the bootloader TFTP recovery process requires Ubiquiti signed firmware, you will need to TFTP recover back to stock then repeat the OpenWrt installation process.

I have up the device in the root... TFTP recover needs physical access to antenna? :frowning: Thanks for reply, anyway. And, which exact version of firmware is fully operational?

If you are using a Ubiquiti power injector it has a remote reset button-- a small hole on on the bottom side of the injector near the Ethernet jacks.

True! I will try later and back with results. Thanks for help, mk24!

I receive an error with Factory image of OpenWRT 23.05.5:

WA# /tmp/fwupdate.real /tmp/openwrt_firmware_factory.bin

Invalid version "WA.ar934x.v8.5.3-42.OpenWRT-r24106-10cc5fcd00

Thanks for reply! Any help is appreciated!

Regards.

I separately discovered this same issue with 24.10.1.

I was able to recover with WA v8.7.0 before flashing the 23.05.5 factory version. A subsequent flash of 23.05.5 sysupgrade is successfully working. Hopefully a proper fix for version 24 is possible.

Recover to WA v8.7.0 with UI or TFTP? I am stuck in this point...

Edit: Impossible downgrade with UI, i will try TFTP method...

Ok, finally solved!

  • Downgrade to WAv8.7.0 with TFTP.
  • Follow instructions of Wiki to install OpenWRT 23.05.5
  • Changed default password to another and after reboot is persistent.

This is it. Thanks for help!

See ya.
