I understand that writing files through the kernel space is not recommended but I have been porting 4.9 to my Android device. While fixing the display, the device stopped booting(Splash -> Black Screen with backlight -> EDL). I had been debugging the device with userspace logging methods but here i am unable to use them. Unfortunately, pstore is broken as well. I tried various methods to fix it but no luck. I can't get serial logs as well since i don't have a UART cable nor is it available in my locality. Writing dmesg output to a text file seems like the only option to me.
