I updated my phone to Version C 087. As Fairphone is unfortunately not kind enough to offer the lates kernel per download, I tried to extract it from the phone itself.
did not help anymore. But this is also the first time, I am trying it on Android 13. So, there must have been changed something in Android 13, I guess.
On the internet I cannot find any hint on how to get the kernel, which is needed to reinstall after rooting and before updating to another version of the FP4.
So, was anybody sucessfull extracting the kernel or knows how this works?
For now, it seems, I am stuck on an unrooted phone…
PS: Here the error message I get when trying to extract Kernel _a (allthough my active Kernel is -b, so I should do it with _b, of course):
FP4:/ $ dd if=/dev/block/by-name/boot_a of=/sdcard/boot_a.img
dd: /dev/block/by-name/boot_a: Permission denied
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000316 s, 0 B/s
1|FP4:/ $
So, it’s obviously a permission problem. Seems, that I am missing a setting, or so…(?)
Did you try with slot “_a”? Your commands should work in general.
This time I used the rooted C-079 kernel for the Magisk installation and that worked well.
