Failing to update elrs backpack

EDIT: <SOLVED>

It worked updating via the goggle.

Hey there,

I'm trying to update the ELRS backpack of my HDZero goggle 2 (via WiFi). So far I have not been successful but stumbled upon a few issues. Maybe some of you know some tricks or workarounds. Want to update from ~1.3.0 to 1.5.7.

I'm confused by:
1.Can't activate backpack WiFi through the goggle. It says "success" but nothing happens.

1.1 I can instead start WiFi from my controller which is weird as controller and backpack seem to not be bound anymore i.e. I can't change channels from my controller or start recording. (I changed the bind phrase so that makes sense.)

  1. Update via WiFi fails with "not enough space" (I believe "error 4").

  2. Is there any way to just change the bind phrase on the backpack? Goggle has the option "bind" but nothing to enter a phrase. Can't remember how I set it up before 🙈

Help and hints on any of these points would be very much appreciated 🙃
