Following, as I got a UXG Lite for the equivalent of USD$45. Thanks for looking into it. How are things progressing?

23

Hello, I updated OpenWRT on the UX. My device is currently stuck in U-Boot, and I'm looking for a replacement firmware. Thank you.

24

How exactly did you do that? It doesnā€™t appear that the device is supported yet.

25

The device was given to me by a friend. My friend attempted to update it with OpenWRT, but it didnā€™t work, and now the device is stuck at the U-Boot prompt.

26

Youā€™ll probably need to try to reload the original unifi firmware for it. Since the device is not supported by openwrt, Iā€™m not sure what your friend tried to do. But equally, Iā€™m not sure anyone here will have a recovery process for you to follow. You should ask on the ui community forums.

27

I tried, but the original firmware is ~ 900MB, so I can't load it via U-Boot. Can you help me?

28

No. As I said previouslyā€¦

thank you!

It's in the Cloud Gateway, ..... drop down Section

I have tried but was not successful. Currently, my device can only be accessed via U-Boot through the serial port

Currently, I can recover the OpenWrt form back to UnifiOS, but it requires two devices and some soldering knowledge to unbrick it.

Welcome to the Openwrt forums, please share how to do this.
