Hi everyone  
I’m not that technical. Can I dualboot between the GL firmware and the latest openwrt 19 on my AR300M?

How can I install the latest openwrt?  
I want to keep the stock firmware too.  
Thanks.

you can use gl-inet firmware on nand and vanilla on nor… i used to do like this… i don’t have the device anymore… gifted to a friend.

> Method 2: using the switch  
> This is only valid in the new uboot (from Mar 2017).
> 
> First ssh to the router and set uboot env boot\_dev
> 
> $ fw\_printenv  
> $ fw\_setenv boot\_dev on  
> $ reboot
> 
> Then when the router boot, the router will choose which firmware to boot using the hardware switch. 1. Left side (near the reset button) → Nand flash 2. Right side → Nor flash

> $ fw\_setenv boot\_dev  
> $ reboot

is this also do-able with the ar750?

answering my own question here.  
edit: nope. might happen down the road for the ar750s but no plans and currently only for 300m.  
note 300m may be only for 2.x software for dual booting.
