Hey guys,
Just wondering if the Sony Xperia Z will come with a locked or unlocked bootloader?
if it is locked, can it easily be relocked after unlocking it for warranty purposes?

I know there isnt much info out right now, but i have never owned a sony xperia phone so,
someone shed some light for me? (:

Devices from carriers usually can't be unlocked. If you buy it outright then usually it can be unlocked. The process does not record your full IMEI and can be relocked after so you are pretty safe in that regard. My HTC takes the full IMEI (so it can be identified) and if you lock it then it goes to "re-locked" and not "unlocked" .... so the sony method is actually pretty good.

Before buying you can always check on a live unit if bootloader can be unlocked.

hmm new to Sony here too. So what are the chances of pre-orders from carriers being bootloader locked? Just to clarify, does that mean carrier purchased devices are useless (if they are locked)? I was planning to get my device from Orange Uk as i can get a pretty decent 40% off the monthly tariff which makes it the best deal for me. But if it is locked then I may need to pass on this....bummer

Well, if i recall correctly, the verizon droid DNA had a permanent locked bootloader too, but the guys here on XDA found a way to crack it.
who knows, maybe there will be a loophole discovered after the first few days?

I'm currently using a T-Mobile Xperia T, and the bootloader is not unlockable. So I would guess the same for the Z.

Though I think early units are generally unlocked (but don't quote me on that but this was the case with my Galaxy SIII and another guy mentioned this for UK network 3).

Is this just the way sony handles it's bootloader?

I unlocked several different phones which were ordered from a carrier without problem. Depends on the device itself!

But Sony seems to be very developer-friendly. There's a developer site on sonys website, where details about bootloaders are posted. Don't know the exact url atm, I'm at work...

For me it is essential to get a phone where bootloader can be unlocked. My first phone was a lg, without custom rom I would not use it anymore...

It all depends on the country. In The Netherlands all bootloaders can be unlocked, even if it are branded handsets from a carrier.

If you're getting any sort of subsidy discount, it's highly likely your device will not be unlockable.

The general rule for Sonys is: If it is sold SIM-locked, you will not be able to unlock the bootloader. If it is sold SIM-unlocked, you'll be able to unlock the bootloader. If the carrier later gives you a SIM-unlock code for a device that is sold SIM-locked, your bootloader will remain locked (Sony is working on trying to change this with carriers).

Sony's bootloader security is pretty strong. If the Z were likely to have a loophole, the T would've probably been defeated by now.

You can cross-flash firmwares for other devices, but you cannot flash anything that has a modified kernel.
