How install a custom rom on sony Xperia Z

[mobi_home]

Hi,
Can you help me for the best solution for my xperia Z in this time (12/2018)
I have original firmware 10.7.A0.228 OS Android 5.1.1 (with king root active) but no TWRP installed. (boot recovery loocked)
I can't boot on a recovery boot for install a custom rom
Thanks you

Dude, check your bootloader. If your bootloader is locked, then you have to unlock it. Don't forget to backup your TA Partition.
After unlocking bootloader, you can install the latest TWRP.
After installing TWRP, you can install any custom ROM you want.
------------------------------------------

The short explanation above is the way to install custom ROM with unlocked bootloader. If your device bootloader can't be unlocked, the only ROM you can install is the stock-based ROM like PureX Z Premium. And you need a different way to install recovery. One of it is the XZDual Recovery.

The rest, you have to find it yourself. Good luck.

What? The service menu may be missing.
You can try to hard reset your device, or make a clean install of the stock ROM (I know, it's a pain in the ass). If this method result nothing, then I dunno what to say, sorry. [Beware, this method could erase all of your data. Only proceed if you have nothing important].

Custom ROM with everything work? I think there is none. But I prefer LOS 14.1 over the 15.1.
