I need your help
I have rooted my FP4 using the mothod first publiced by hirnsushi in this post.
Then I wasnt willing to manual update my phone for every upcomming update, so I uninstalled magisk and wanted to lock my bootloader again. This was a big mistake. I was stuck in a boot(loader) loop. After some days of trying diffrent things i got the fastboot flashing process working with manually installing some Samsung ADB drivers over the device manager. kinda sketchy i know.
Then I flashed the A.067-boot.img and my FP4 started working again. Kinda, my WLAN function is broken, it wont active and my System UI randomly crashes.
Question 1: Could anyone give me a short tutorial how i can get my FP4 to the stock factory settings?
Question 2: How do I boot in fastboot mode?
Question 3: Does someone have the right ADB drivers? (my phone is only recognized in fastbootmode, not if its normaly turned on and connected to my PC)
If you have any questions please feel free to ask
thanks in advance
