Looking for sony xperia Z family now it is necessary.
Some freeware of this machine is required.
It may be a very old and very rare version.
Because people are not popular to play But who knows the source or where to find it?
That is, I can't find it for a long time.
Went to get 1 carcass, the battery is damaged, the screen is broken
Really want to help.
