Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.3.0
Is there any way to revert to firmware version 2.2.5 on the ER605 v2?
I've only been able to revert to version 2.3.0, and after that, nothing works, not via TFTP (which doesn't work), putting the router into recovery mode, or through the website.
I need to install OpenWrt on it, and the only way to do that is by rolling back the firmware. Any ideas?
