Plenty of issues, so first just setting up the environment is already quite complex, then I had to do various patch to the device tree to get the test image working and the test image kernel booting. The only thing I managed to do was getting a shell and having the vibrator working, apart from that, all the other libhybris tests were failing with segfaults and I could not understand why.

Difficult to say, I'd say that each phone is likely to have issues in different ways.
