Anyway, I would like to install the above ROM on my serranoltexx. In the changelog, the developers say that in case I'm coming from a 4.4.2 ROM (I actually have PA 4.4-BETA1) I would have to update bootloader and radio too.
I tried to ask on the AOSPA Legacy group on G+, but still got no answer. I wondered if anyone here could tell me whether I really need to update bootloader and radio, and where to find versions compatible with android 4.4.3.
Thank you for your help!
EDIT: I got an answer from the G+ thread, bootloader and radio update are necessary only for nexus devices. Thank you anyway! Should this be deleted or closed? (someone else could have the same doubt)
