About waranty

If I just root my xperia z without unlocking the bootloader, will it void my warranty? Or installing custom rom with locked bl?

May be you not replying for this thread is a way better than giving false answers when dont know the answer.

Root. Do whatever you want.
Need service? Flash stock before taking the phone to official service.
Same can be said about unlocking the bootloader.
But XperienceD is right, rooting DOES NOT VOID THE WARRANTY.

Wrong : The Free Software Foundation Europe argues that it is legal to root or flash any device. According to the European Directive 1999/44/CE, replacing the original operating system with another does not void the statutory warranty that covers the hardware of the device for two years unless the seller can prove that the modification caused the defect, accroding to http://en.wikipedia.org/wiki/Android_rooting
So even if Sony, or the president of the usa, or Thor himself said that void warranty, that's not true.

I've been there personally. Took my Xperia S, another Xperia S, an X10, and an Arc to service.
All rooted no problems.
I even took my previous Xperia S bootloader unlocked to have the screen replaced. Totally forgot to lock the bootloader. They yelled at me because I wasn't covered by warranty, but they kinda know me already as I buy all my phones over there (they let me play with the Z Ultra too ), they spared my life and didn't charge the 150€ they charge for having the screen replaced without warranty.
Sony service is great here in Spain, if you take the phone personally. Not so much when you have to deal with delivery system.

Awesome.!! but the Sony service rep here in India are kinda dumb. But I can deal with it. Thanks a lot for your help guys

Haha sure do it, it's totally legal to root your phone, even in India.

So even phones with unlocked bootloader, they need to prove the damage is because of the software we used! Am I right in this?

Yes and no. The service that is in my city is very clear about this. What they told me is that they need to register te parts replaced with their software, maybe serial numbers to keep control what goes in and out,, but they can't do so with the bootloader unlocked as they cannot flash stock firmware with the tools they have.

Wrong, a phone with a locked bootloader can be flashed by any flash tool made for Xperia Z, it's only if you unlock the bootloader that they can't (SUS and PCC don't work on unlocked bootloader), and btw that void the warranty to unlock the bootloader.
And yes they need prove that the modification caused the defect if any.

[Q] BIONZ work after relock the bootloader?

Hi guys!
I've read several threads about loosing the BIONZ after unlocking the bootloader. Some say it depends on DRM, some say it has nothing to do with. It's possible to regain it after relocking the BL?
What is truth about this?

Unlocking bootloader makes no change to software...just make sure u have a TA backup....

Actually it does make a lot of changes to the software. Just take a look at the stock rom logcat straight after booting. There's a check if bl is unlocked and if it is then it wipes some stuff.
TA backup is very important before unlocking it so u can go back to LB and send your phone in for a warranty. I can't tell what's up with the bionz as I've unlocked my BL and then restored it, but the camera doesn't seem to be as good as it was. That might be caused by 4.4 firmware though. Can't tell for sure.

I unlocked and Track ID working like always. Do you want a vid?

Woot? I just say that track id works even without DRM. And its not market downloaded
Skickat från min C6903 via Tapatalk

some unlock bootloader guys confirm track ID work but they cant use update music info feature in walkman app, x-reality stop working, picture quality lower than lockbootloader
( im not sure, just read from google, should we make a thread to vote and confirm what feature stop working after unlock bootloader ?)

I can say it like this then.
I unlocked lost drm keys forever. I relocked my phone using flashtool. Drm keys still not there according to what we know.
But all the functions you mention works. I've compared pictures with ones that comes from a locked bl with never was unlocked. They are the same quality. The other functions you mention works aswell.
And remember now, I don't have any drm keys. But I have relocked bl. I unlocked last night again. And I actually checked these things just to see and guess what. They all still worked.

[Q] Unlock bootloader

Hey guys. I'm trying to unlock my booaloader of my Xperia Z C6603.
When I go to the service menu and check it says "Bootloader unlock allowed: No".
The point is, that I haven't bought my phone from a carrier, it's unlocked from factory and I don't know why I can't unlocked it

If it says "No", then it's permanently locked.
Did you purchase it brand new, directly from a store or used from a third party?

Then it's possible that the seller flashed generic software on a carrier supplied phone that they network unlocked before selling it to you.
You should contact Sony support and they should be able to confirm this if you supply your IMEI number.

Sorry to hear that.
Did the seller advertise it as an unbranded phone? Perhaps you can contact eBay to see if something can be done, even if it's some time after purchase. It's worth a try.

You cannot unlock a BL locked phone using flashtool.
If you want a different rom there are plenty of stock based custom roms just use the search function

It 100% won't work. You may soft brick the device, but most probably it will just fail with no adverse effect.

Z3+ Bootloader Unlock

I have the single sim international version of the z3+ and it says the Bootloader is unlockable in the service menu. So the question is how do I go about getting it unlocked?
Sent from my E6553 using Tapatalk

If it's indicated as unlockable, then there's no way to unlock it.

There should be instruction on Sony's website. Unlocking bootloader doesn't do anything for you unless you know what you're doing. It doesn't give you root access but erases your TA partition where you will lose all of Sony's DRM keys.

I'm aware of what unlocking the Bootloader does. Honestly don't care about drm or warranties as I never have phone long enough to break them anyway.

Sorry, I may have read it wrong and replied too fast. To clear any doubts, please indicate what exactly is stated in the menu. Is it "Bootloader unlocked allowed: Yes"?
In any case, this is the Sony site to unlock your bootloader: http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
That being said, I don't see why you would want to unlock your bootloader now. There are no custom ROMs or kernels developed for the Z3+ yet. You can't even root it.

Got a question
Got unlocked bootloader without possible root (5.0.2v 28.0.A.8.266 firmware E6533 (z3+ Dual)). Used flashtool before unlock and saved S1 Dump in Advanced menu. Is it possible to get DRM keys from S1 Dump and restore bootloader lock?

you should downgrade to the 251 firmware so you can flash the modded stock kernel for root access.im using imagebreaker kernel. check out zrom also

Ok pikeylfc,
I see that imagebreaker kernel is for e6553 device. Mine is e6533 (Dual sim)... I doubt if the same kernel can be used... It has different hardware.

Not necessarily. When you have active myXperia service, service tests will show, that bootloader is not unlockable. Try to disable myXperia (Settings -> Lockscreen and security -> Protection in myxperia (or something like that) -> disable/deactivate). Then reboot your phone and check again. It's high probability, that bootloader change state to unlockable in service tests. myXperia is asking you to turn on in initial configuration (if you have new phone or after wipe), and most people turn it on by default and forget it.
