HTTP Firmware upgrade path for BETA release is:

firmware.grandstream.com/BETA

Note:

1. Devices on firmware 1.0.9.x or below cannot upgrade to firmware 1.0.11.9+ directly through WebUI. Please upgrade via HTTP/TFTP.

2. The first time you perform an upgrade from 1.0.9.x to 1.0.11.9+, the phone will first upgrade to 2.0.11.x and then upgrade to 1.0.11.x. This process is automatic when upgrading to 1.0.11.x, so if you see 2.0.11.x as the alternative firmware, you can ignore it. For all future upgrades afterwards, it will upgrade directly to 1.0.11.x. (Except legacy hardware). Please refer to for Release Notes more details.
