Hi, the beta is available to your account now. Please refer to the steps below to upgrade it via the DJI Assistant 2 again.
1. Log into your DJI account.
2. Upgrade the firmware V 01.03.0813.
3. Once it's done, please press the "Record" button on RC and make sure it's recording, then start to upgrade firmware to the latest version, it will be working.

Try what DJI Thor said,

But i do want to point out i've seen many threads here about failed upgrades and unfortunately i'm one of them!
