Dear support team,
have a brandnew SPA525G2 here for testing, came with 7.4.6 I think.
I upgraded successfully to 7.4.8.
Then I needed to test behaviour in older firmware, so I went down step by step to 7.4.7, 7.4.6, 7.4.4.
Everything without any problems.
No the phone is on 7.4.4.
Problem is that I cannot go up again to ANY other firmware. All newer don't work, 7.4.3a does't work, too.
I also did a factory reset - without success.
How can I get back newest firmware now?
I performed all actions via http frontend.
Thank you!
Markus
