What doesn't work well
+-
+
- I had to disable -Werror in order to compile the kernel +
- Screen is laggy +
-
+
initfs hook
+
+ -
+
Splash screens don't work and I cannot get framebuffer working in initramfs
+
+ - Screen is black after I've entered the password. Workaround: +
sh /etc/postmarketos-mkinitfs/hooks/00-device-motorola-titan.sh`-
+
- Cannot boot if kernel is XZ-compressed (it boots if you build it using Android's build system) +
- flash_kernel: boot image is too big +
- flash_system: Invalid sparse file format at header magi +
-
+
wifi: requires wcnss-service (some work already begun in titan-wifi branch)
