Attention - IMPORTANT 👆👆 for users of IPTV (SUNRISE, SWISSCOM etc... ) Please do NOT install firmware 7.50! 👆👆 Tested on FB 7583 - suspect 🙄 that this also applies to FritzBoxes 7390/ 7490 / 7590. The TV boxes request parameters (section: 'jasonii' ) in the settings, which is NOT adopted by the new firmware !!!. When replacing the Sunrise FB I always imported the settings into the next higher firmware - after approx. 1 week the TV box reported - account locked -. After more than 3 hours on the phone with Sunrise support (great people), I took the FritzBox and analysed the '.export' file of the settings - result: NOT ALL settings are adopted. 🙄 So I DOWNGRADE the firmware back to version 7.31 - everything works again 😰😰 puhhhh - the exact procedure for the downgrade is explained well on the avm.support page. A downgrade back to version 7.29 is currently offered. no problem, I had saved the file with version 7.31.... This result was reported to AVM support - the ticket is still 'in progress'. So far, unfortunately, not good - but mistakes can happen in software development, even those that slip through QA. (in this case the provider versions were not on the radar) - human 🤷‍♂️ Greetings Rainer
