Since there is no separated forum this phone and i cant find answers on my questions iv started a new thread so....:
1. Why the speaker is so quite, and when start play music with xloud on it crack but its ok with xloud off is it just me?!
2. How can i root without unlocking bootloader since i dont wanna loose drm files( did they even important?! )
3. If there be some forum just for xperia U/P or we need to post in this ection....
P.S. previousely iv had xperia x8 so im new with this xperia, and sorry if this questions are already answered....
Is there anyone who can answer to my question....
1: The same cracking noise from my speakers too with xloud on. Also the sound is low. It seems to be due to too small speaker.
2: I don't think you can root without unlocking the bootloader I searched around a lot but didn't find anything.Yo can try the method created by DooMLoRD but you'll still lose DRM files.
3: As Xperia U user I'm waiting for a separate forum too
OK, but what exactly will i lose if drm files are deleted....
Please note that you may void the warranty of your phone and/or any warranty from your operator if you unlock the boot loader. Sony Ericsson can then no longer guarantee the full functionality of your phone, and will not be responsible for any unsigned custom software being flashed to the phone after the boot loader is unlocked. Certain functions in your phone might cease to work, and performance might not be ideal. You might also damage your phone permanently. In the worst case, unlocking the boot loader will cause physical injuries or material damage, for example, due to the phone overheating.
Certain content on your phone may also be inaccessible due to the removal of DRM security keys and the secure user data partition while unlocking the boot loader. We advise you to create backups, since user data, settings and accounts will be removed.
this is what was said in sony official site
Since iv send my phone to repair because of speaker crack i cant do anything right now, but when it came ill try with flashtool just to root my phone and see what would happen, since with x8 i were able to root phone without unlock bootloader just with flashtool, and on official flashtool page says that xperia u is supported...
DRM is the protection given to music files bought legally. You might not be able to play such files.
This is what I believe.

some simple question... if i flash my phone with any of thouse ftf file my warranty will be intact.?? coz my phones SI is not listed on the list. my phone is generic world. and if i use any ftf files if anything goes wrong will ill be able to update my phone through sony's pc suite software like useal?
and one more thing, which new features sony has given on this update other then the walkman and some media changes?? from the video which sony posted for ics 4.0 i cannot see any noticeable update from sony. all are ics basic features. so i dont understand for what sony took this long to relese ics???

Flashing MAY void your warranty, if you screw up phone with flashin 95% you will have to pay for repair.
5% depends how lucky you are.

just never unlock you bootloader (so you keep DRM keys) and your warranty will be intact! i think you could receiver a upgrade for you fw maybe when it will come out, like the "official upgrade" but i'm not sure about this! you should don't worry about this, you can flash back every firmware anyway!i suggest you always a recovery, but for now seems nothing work for ICS, i'm waiting too, coz i got wifi module of doorkernel not working so i can't use wifi with ics, that annoying
Unlocking only your bootloader does NOT void your warranty anyways...-may- doesn't mean -will-.

but anyways, if you are just flashing theres a very small margain of screwing it up, because flashtool (for using it for updates) essentially does exactly what the SUS or PCC does, just you can pick what you want. If you plan on flashing, just be sure to have the most up-to-date Flashtool, and read the directions.
@andyus: The reason why DoomKernel and such doesnt work yet is because the one you are trying to use is for GB, you will have to wait for the ICS version to come out before you can use recovery and such again. You shouldn't even try to use a GB kernel on ICS...it will never work properly.
Hi,
my question consists out of two parts, firstly:
Which (Sony) apps make use of the DRM-partition / DRM-keys?
and secondly:
Will my Xperia tablet Z function as it should if I backup my DRM-partition, unlock the bootloader, install a custom kernel (on stock but rooted firmware) and restore my backed up DRM-partition, effectively re-locking the bootloader again?
Thank you in advance.
Best regards.

Sorry I can't answer your specific questions, but here's my experience :
I made the mistake of unlocking the bootloader before backing up the TA partition and lost my DRM keys.
This prevented me downloading movies/music I purchased in Sony Entertainment Network using the stock Sony movie & music players.
(Fortunately I purchased the items with my free £20 credit that came with the tablet Z, and I can watch them on my Playstation. Also the SEN store is too expensive so I won't use it again anyway!)
I just use other services (Google Play Music, Amazon MP3, Google Movies), or rip my DVDs. All fine.
It has also been mentioned that the Bravia Engine will stop working. I did go back to a stock ROM at one point, and it let me select Bravia Engine in settings - but I don't know if it worked or not. Some people say it only makes the picture look false anyway.
I guess it may affect re-sale value, but most trade in sites I've used don't bother checking that level of detail. They just want the basics - device turns on, etc.
So, I've got mixed feelings. Kicking myself that I didn't read up more and back-up the DRM stuff before unlocking the bootloader...but not really missing out.
Thanks for your reply.
Bummer you lost lost your DRM keys.
I have the tendency to read a lot on the subject before I attempt it.
Judging by your post the only interesting thing that would stop working would be the Bravia-engine, I don't know how/if it enhances the image, I'll disable it and check the result once I get home from work.
I don't really care about SEN or any other Sony app, only the IR remote app and the sixaxis PS3 controller app I find useful, these need to work, and maybe also the Bravia-engine.
Any thoughts on the bootloader question?
Will the device boot if I install a custom kernel (Doomlord's for example) and re-lock the bootloader?
I can't see why it shouldn't boot but you never know...
Don't want to brick my brand new 500€ device...
Edit:
I should read some more before asking stupid questions:

Hi everyone, sorry if this is the wrong spot to ask.
I have pre ordered a Z2 and since I am new to android and have always been an avid jailbreaker, would like to root my Z2 and eventually play around with custom ROMS.
DooMLoRD announced today that Touch Recovery is working on the Z2 so it can now be unlocked and rooted. I have a few Q's specific to this process.
1. Correct me if I'm wrong but at the moment there is no way to root the Z2 WITHOUT first unlocking it?
2. You need root to do a TA backup, so the current process of unlocking then rooting will result in lost DRM keys?
3. I read that unlocking wipes all data. Does that mean that the Z2 is then unbootable until you have flashed a ROM. Or is the stock ROM still actually in place and bootable, just without any user data?
4. What specific features are lost when you don't have DRM keys? I read something about losing functionality in the photo album and walkman apps, and bravia engine (but that may have related to unlocking the Z!).
1. You are correct.
2. Correct again.
3. The stock ROM will be in place and the phone will be usable, but all user data will be wiped.
4. I have the same question for the Z2. I haven't seen the answer anywhere, but I think @DooMLoRD and @yeeson should know...

When you say this, what exactly do you mean? Since a phone has a lot of functions. Calls still work I presume, as well as wifi and mobile data. Camera, audio, play store and google apps etc...?
I thought it was just a few Sony specific functions that stop working, like Sony's OTA updates.
It seems blog sites all over the net are reporting this method of rooting as an easy user-ready option. In their rush to get hits, they are completely neglecting to mention the fact that at the moment this is a one-way process, and that there are some very specific downsides to rushing into rooting the Z2 at the moment.
I hope people are doing their reading first

But you only can relock the bootloader only if the Z2 gets a proper root with locked bootloader in order to perform a backup of the TA partition. Once you unlocked it without backup, DRM keys will be lost forever and you'll lose your warranty and you won't ever be able to relock it again. No you can't use the TA backup from another phone. It would hard-brick your phone. I hope that helps!

You MIGHT lose X Reality. DooMLoRD has tweeted a few days ago that all devices with 4.4 that unlock their bootloader will not lose it anymore, but, not that I don't believe him, but I will only be 100 about that seeing many confirmations.
Also, I think you might lose the possibility to use Music and Video Unlimited. Haven't heard anything about PS Mobile, but I think it is included. Can't remember anything else...
Hey Guyz,
New to XDA-Developers platform,just wanted to get your help on rooting Xperia Z2.
I want to mirror my xperia z2 on my laptop. All the applications around need rooted phone to perform this action. Although some are working with USB cable option,but not working at my side either.
I have already downloaded all the necessary tools for rooting,the problem am facing is selection of my firmware
My Phone Software Version is 1278-4770_23.0.1.A.0.167
I want to remain on my 4.4.4 version of kitkat and root as well,till now i have learned that my software version supports German Unbranded FTF file for root.Can anyone provide me that file or some link.
Accept my Thanks and Wishes in Advance
Regards
There are many ways to obtain root access with the xperia Z2
Now keep in mind this:
There is a easy way and a hard way
The easy way voids your warrenty permanently and the hardway alows your warrenty to be restored
Think about this decision and pick one
(ill guide you through it)

I would definitely NOT say downgrading is a very hard way, that's just outright over exaggeration.
There is no easy way or hard way, only a quick way which voids your warranty and there is a longer way that won't void. The longer way takes about an hour if you download all the files previously.

Take note that you CANT get any repairs from sony even if you want to pay, check that you are satisifed with your device aka no defects
Note that you lose some xperia functions, X-Reality, SuperVivid and some Playstation and sony apps dont work from my testing
Now lets get started
You will need this tool for unlocking your bootloader and flashing a recovery
http://www.flashtool.net/index.php
You will need this tool for installing the fastboot/flashmode/Z2 drivers for Z2
https://www.google.co.uk/url?q=http...KA9T2g&usg=AFQjCNEKiBoUgTCpZhx3dv1GJigiYpH2WQ
After unlocking your bootloader flash this boot.img to your device using flashtool
http://forum.xda-developers.com/showpost.php?p=56540642&postcount=54
Next you will need to download supersu
http://download.chainfire.eu/supersu
You can use twrp to flash this which will root your device
If you need help more than i have explained here then ask
Concider the losses from void warrenty and the few lost services
Do not use twrp to flash anything from another device, mods yes but anything more than just a mod is NO

It blows my mind that people elect to destroy their drm keys when keeping them takes an extra 10 minutes. It is safer to do and can always revert back to stock if your phone screws up.
Although you have been told that on 4.4.4 you lose warranty, camera quality, ps4 remote play, all the xperia unique apps like lounge. How do you know what you lose on lollipop?
Each to there own, I know I've been stung by this is the past so I would never destroy my drm keys again.

actually funny enough I've learned that the lack of warranty or Xperia features phases none on some people just because they have a well working unit and most likely wont need a warrenty repair or replace
i kept my TA due to the fact i had 4 defective units in a row however with my Xperia S i had no need for them and similar with my current Z2
whats your opinion on this

To be honest i think it would be better to downgrade even if its just for the sake of taking a backup of your TA partition. i myself will be going stock lollipop once official CM or PA ROMs roll out, but i would still like to have a way to get back my warranty just in case its needed. currently neither rooted nor UL BL.

Dear community,
I've recently got a Z5 compact (updated it to MM already) and after reading around here and around the Z5 forums I came to a cruel conclusion (didn't do my homework before getting the phone, but that's my problem):
You cannot root without unlocking the bootloader and you cannot backup the DRM keys without having root access.
Is this correct? If so, how did people writing the tutorials about DRM keys backup achieve root access in the first place?
I'm a little bit confused here...

currently,for the z5 family,there is no way to root without unlocking bootloader.Period.
the tutorials you see on the z5 pages are ways to restore sony credentials after unlocking bootloader but does not restore TA partition (where the DRM keys are) which is lost once you unlock bootloader. i.e you trick the phone into believing the bootloader is unlocked and can still enjoy the sony goodies with the patch (very simplified explanation here).
older models are able to achieve root (like the Z3+) only recently due to exploit found on MM and also using older firmwares.
you might want to hold back on unlocking bootloader for now.the z5 has impressive hardware rivaling samdung.the sad part is backing up TA partition while bootloader is locked,which has not been found.
that or you can hold out till the new nexus arrives.
Frostmore is correct in that you cannot backup DRM currently. But I disagree that you should hold off on doing so, the z5c lacks in most all places and root helps fix some stuff.
Does the loss of DRM keys affect camera performance?

yes it does, Mobile Bravia Engine is gone, Track ID in music player is gone and camera performance is also gone.
but now you can backup and restore your own TA if you have not unlocked bootloader yet
I thought that It is possible to backup TA partition with iovyroot here. It is working on Lollipop. So if you upgraded to Mashmallow, you need to downgrade with flashtool here which does not unlock the bootloader. After downgrade It is possible to backup DRM keys I think isn't it?
Yes downgrade then unlock boot loader then root then relock with DRM keys.

I am completely baffled. I managed to restore ALL my original DRM keys!
I lost them while unlocking the bootloader, and then rooted my device. I also didnt do my homework and didn't realise I would lose all the DRM keys. When I factory resetted my device, using companion, I got my phone working on android 7.0 again, but ofcourse the drm keys were gone. Filming was almost impossible and fingerprint was not working etc.
And for whatever reason, guess I was bored, I unlocked the bootloader again, since it wouldn't matter anyway. So I unlocked the bootloader with oem unlock and the sony developer site, and then the device started rebooting. It looked like a bootloop, it took about 5 minutes, everything on my phone was gone (damnit). But when I tried fingerpringt, camera, everything worked like before! I have no idea how this happened but maybe this'll work for anyone here. aswell! From now on I'm not gonna touch ANYTHING anymore, since I just don't have enough developer knowledge.
btw: I made an account on this site especially to share this information with you :highfive:

Welcome to XDA, and thanks for going through the trouble of creating an account to share information.
However, some of the information you shared is either wrong or misinformed.
Also, this thread is quite old, digging up old threads is generally frowned upon.
First of all, if you never made a backup of your DRM keys before unlocking your bootloader, then those keys are gone. Forever. There's absolutely no possible way of restoring them.
Second, missing DRM keys do not cause the camera or fingerprint scanner to stop working. Only certain "enhancement features" are disabled, such as X-Reality that makes images appear sharper and more vivid when viewing photos/videos, or advanced low light noise reduction when taking pictures.
Many of those DRM-reliant features can be re-enabled by applying a DRM fix patch that can be found on the XDA forums.
The fingerprint scanner is disabled for certain region's firmware by Sony via software means, but it is not dependent on DRM.
You probably messed up somewhere flashing or rooting your firmware, causing functions like the camera and fingerprint scanner to not work. Do a factory reset or clean flash in case this happens.
And finally, it is clearly worded on the web page where you go to unlock the bootloader that your phone will automatically perform a factory reset upon unlocking the bootloader, so you shouldn't be surprised that all your data was erased. It's expected behavior.
You should always backup your data before fiddling with your phone, it's good practice and common sense.
So in conclusion, no, there's no way of restoring the DRM keys without a prior backup. You didn't manage to restore it.
Here's how to verify if your DRM keys are present:
In the dialer, input *#*#7378423#*#* to enter the service menu
Service tests > Security
If your keys are intact, the first three lines should all say [Key OK][Active], and at the bottom FIDO_KEYS : Provisioned
You probably fixed your camera and fingerprint issues by performing a factory reset unknowingly, which is done automatically when you unlock the bootloader as mentioned.
