Don't know if that's standard in Japan but i bought the XZ from Vodafone (Germany) and the bootloader isn't locked.

You're reading manuals?

Never ever had a look inside them

I am new to Sony phones but experienced on HTC. Does Sony use S-ON/S-OFF like HTC does or is a rooted Xperia Z simply just s-off? I´m thinking of getting one onstead of my One X

AW: [Tutorial] Xperia Z & ZL Bootloader Unlocking
Mixed thing, I believe, as sony uses different concepts. S-ON/S-OFF prevents flashing stuff using a custom recovery, correct?

Edit:
I can give you information which I know from the Xperia T, a device which applies the same concepts as the Z. Everything which applies to the T will eventually, most likely, also apply to the Z once the exploits to obtain root are found.
Ok, so, a locked bootloader prevents you running custom kernels and an custom recoveries "natively", meaning on a locked device you cannot natively boot a custom recovery. It's comparable to S-ON I believe. On the T devs managed to circumvent this by obtaining root on a locked device and then used root acces to modify the chargemon script which is run upon booting the device to make it load a custom recovery additionally to it's intended function. The recovery is not flashed on a separate partition but deposited on /system as an archive. The script simply unpacks and loads it. Because the recovery runs with root permissions, you can then use it to flash stuff despite having a locked bootloader.

On an unlocked device, you can flash any compatible kernel and recovery and also natively boot them. An unlocked bootloader means full and unlimited access to the device.

yes... with S-OFF u can flash radio and kernel in recovery...


on Xperia devices with unlocked bootloaders u can flash kernel in recovery... we never really tried flashing RADIO image (baseband) but i guess it should work...
