Thought I would share my CM 12.1 experience.
I like the xperia z1, but with the pain and hassles of rooting , lack of custom roms etc I probably would not have bothered.
I stupidly didnt back up TA before u/l bootloader and lost my DRM keys, no ...
Where can I download this ROM? The links are dead.
It was a bit confusing, but latest ones are here
Do at your own risk, I an still downloading
