DRM keys - Xperia Z Q&A, Help & Troubleshooting

I am just curious really. When you unlock your bootloader you, as we all know, lose the DRM keys. Why can't we get them back? What's the actual mechanism that prevents you from say taking them from someone else's Z and copying them over or something?
Are they unique to the indictable device?
I have a permanently locked bootloader so can't really try anything. Just interested to know about it.

Ride it like you downhill it.

Sony creates these keys with a yet to be cracked algorithm.
And yes they are device specific, most likely bound to your IMEI.
And this is checked in the earliest stage of booting.

Exactly the answer I was looking to get. Thanks for that.
So we have to wait until some of the genius devs can create a work around. Hopefully soon lol.

Most of us pre-ordered and got an extra item instead.
Some got the Sony MDR-1R
Some got the DK-26
Some got bluetooth speakers etc etc
Maybe that's the reason. I don't think people can still get those items anymore when they buy the phone, but these without the protector included are still from the old batch.
Who knows...

Sand inside the power button

So I decided to take my awesome waterproof phone to the beach and I took amazing photos however, there is sand inside the power button! I hear and feel the crunch when I press it, also some inside the volume keys, I've searched online and I can't find any answers...no surprise there but if I was to send my phone off to Sony would they repair my phone as its under warranty? I am afraid they will reject it because its not "Sand proof"
Please help
I am running a custom ROM but if Sony do accept to repair it, it won't be a problem to revert it back to stock.
Sent from my C6603 using xda app-developers app
It is supposed to be "Dust proof".
But the User guide clearly states "No swimming", "No sand", "No sea water", so...
Damn! So I presume if I were to send the phone to repair they will tell me its not covered under the warrenty?
Sent from my C6603 using xda app-developers app
Most likely your problem is qualified as misuse, those reparations are not covered by warranty.
Ahhh no! Well this sucks, thank you anyway, I'm going to talk to Sony in the morning, see what they say but I'm sure they'll tell me what you've just told me

Mist on the mirror of camera

Mornin'! (at least here in PL)
Yesterday when i was in jacuzzi i decided to take some underwater pictures using my Z. Ive heared it isnt designed to be submerged, though of course SONY promotes it as it does. Ok but lets move to a problem. After first picture taken accuracy gone bad, the water was clean but pictures of even close localised things were blurred. I remember someone here on forum showed his underwater pictures and they were great actually. Mine were not worth a penny... After bathing i had swab the water all of my device and then i saw the mist on the interior site of mirror of camera. Now its already gone but had been there for few houres. Camera still works perfect after mist had gone, no problems there, however mist is an evidence of water coming somehow through. All of the indicators are white, so its not where the problem comes from. So my question is are you guys facing with such a thing after bathing, is it normal or is it as i said evidence of malfunction? Next question if i bought my Z from polish network Play does it mean warranty is ensured only by them or i can take it to SONY Center and they can fix up this issue too?

Some people are def. confused. XZ was never designed as underwater camera. Keep it safe and out of water.

I hope so, anyway Im going to take it under warranty to check whether everything is ok. And back to my question: can I take it directly to SONY Center rather than taking it to local network provider who sold me my phone?

Probably. Along as you have proof of purchase. But if there's nothing wrong theres nothing they are going to find. And probably charge you for wasting their time

Slow GPS positioning.

I don't know if it's just my handset that has this issue. If it's an issue at all.
My GPS takes forever to find my actual location. Leaving central London yesterday on the M4 the GPS around 25 minutes to find where I was. It isn't really acceptable to be quite honest.
Is there an issue or is it a handset fault solely affecting me?

My GPS locates my position in a couple of seconds.
Have you tried the GPS Test on service menu?

Done. It took nearly an hour to find a signal. But it found one... I don't understand. If the hardware is working why isn't the signal being detected in a normal time frame.

Have you tried reflashing a stock rom. And see if the problem persists. If it doesn't, you probably have some tweak or module doing stuff to the gps.
If the problems still there it could be your carrier or a faulty device.
Flashed back already. Several times. I haven't got any tweaks or changes going on, the only reason I rooted was to rid myself of the bloat.
This is really annoying me, if I have got another crop handset off Sony I will definitely be going back to HTC phones.

Are you removing fast dormancy? For some carriers it's needed.
I think so. I have basically now gone down the route of stopping the phone cutting any process off for any reason. Still the issue persists though.

this is just a wild guess, but worth a shot.
try redownloading the stock rom, check md5 and be sure to make a clean install.
try download "FasterGPS" from playstore, to get the time from a ntp server near you, to avoid wrong time for the fix due to delay on a long travel from the ntp package

XPERIA T no update to android 4.3

Looks like it is made by a 5 year old and Xperia T is twice in the image, 1 with YES and 1 with NO.
Looks fake to me.
Edit: And the Google edition of the Xperia Z will be updated by google of course... and don't know why it is in here anyway

Different strokes... Wait until you take a picture on the Nexus 4 (or from what the specs say the 5). Unlike the Sony, it is truly horrible camera.
The trick is never buy a subsidized phone, then it won't be simlocked or bootloader locked. That was an option with the Xperia T. I picked up mine for $279 at newegg.
The camera on my t is rubbish. When you take a video all you can here is a clicking noise from the camera

just to make sure what u talking about...you mean a noisy autofocus rattle sound, in videos?
if thats what you mean, i had that too with some Roms, but with omniRom its gone for me. dont know why. guess its a problem with some mic or whatever. happen for me just with some roms, not with all...crazy huh
thats your problem?
Maybe the Xperia T LTE is the one getting 4.3 update. I think the 3G one will not get the update. Maybe i'm wrong.
Neither are just like what happened to my play. A phone with specs good enough but not given the updates on purpose. If sony want to gain the market they need to release 1 flagship a year and support their previous flagships for longer than 5 months. The galaxy s3 is older and is getting android 4.3 and why aren't we?

I also will no longer support Sony's devices after this, kind of a slap in the face. They can take their T and stick it
this is what sony deserve after they screwed my over twice. First with my xperia play now with phone. No wonder why xperias depreciate so quickly

Because no update to new version and sony bad, nexus cool because google. New version is good, because it keeps on battery half hour longer/lasts shorter but better. And profiles/new function in camera which i will use two times in my life/better integration with google plus omg! And no new version means that flagship abandoned. I am betrayed. sony bad.
To be honest i don't understand it too. When it comes - it comes. If not - who cares. Update from 2.3 to 4.0 was a big deal, because everything changed. API, nature of Android etc. GB slowly died and became incompatible with many interesting apps.
But update from one jelly bean to another? Dudes... It's only features!
Please just be happy that Sony released quite recent well written Android version. It's highly optimized and allows to do almost everything that is available to 4.2 and 4.3 devices..
