Hello everyone, I hope you are all doing well. I am facing a critical issue with my Fairphone after updating it to the latest Android 13 release on October 2nd. Unfortunately, I have encountered a persistent black screen problem during the boot process. I have tried several troubleshooting steps, b…

Hi everyone, Thank you for being so active on this topic and helping each other out. I read all your comments and shared a summary with the relevant teams.

I get that, but it’s still a different issue that only compounds the problem.

[image] yvmuell: Well things happen and thats how A/B devices work Thanks for that really interesting link to TDA. So, what could that mean for a broken FP4, at least with an unlocked bootloader? Could changing the actve slot with TWRP help? And if not, maybe flashing both slots with the new …
