I have a device that comes with OpenWRT pre-installed. The firmware version is OpenWrt 18.06.1 r7258-5eb055306f.
There currently is no support for this device on the OpenWRT site, though. I specifically want to upgrade the pre-installed OpenWRT firmware to 19.07.2.
I have found a device on the site, made from the same manufacturer, that comes with the same pre-installed version of OpenWRT (mentioned above). See device here: https://openwrt.org/toh/gl.inet/gl.inet_gl-usb150?s=r7258&s=5eb055306f
The GL.iNet GL-USB150 has support for the newer 19.07.2 firmware.
Since my device came pre-installed with the same pre-installed firmware version as the GL.iNet GL-USB150, does that mean that the v19.07.2 firmware for the GL.iNet GL-USB150 device is compatible with my newer device?
I hope my explanation isn't too convoluted. Any input is appreciated. Naturally, I want to try to upgrade my new device's firmware through LuCI using the GL.iNet GL-USB150 firmware, but I'd like to avoid bricking this thing since there is not much support yet.
