New Firmware for Slate AR750ext

If you have an older AR750sEXT with old uboot code, it will not load any firmware newer than the 3.104 firmware img file. If this is the case, you have two choices:

  1. Update the uboot code, then load the newer versions of firmware.

  2. Load 3.104 firmware img file, and then doing a multi-step update using the GUI and the tars firmware files starting with 3.105->3.216->4.x

Look here for information on the new uboot code.

Make sure you use the correct uboot file, or your router will become permanently bricked

If you want to try the 3.104 firmware img file, it was recently put back on the GL iNet firmware site by support, and is under Legacy
