[Q] unlocking bootloader - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Hi all! Before buying an xperia mini pro SK17i i wanted to ask something in order to get if i did understood what i have read on the forum.
I have read here (http://forum.xda-developers.com/showthread.php?t=1568792) that there are 2 way to unlock the bootloader on sony xperia 2011 devices (like the mini pro). The "test point" way is defenitly not for me. I am too noob for that. I can only do the "offcial way". Now i have two questions about this way of unlocking the bootloader:
1) By unlocking by this way i will loose DRM and TrackID. What are these 2 thing? Are they important?
2) Together with DRM and TrackID, will i loose warranty too?
3) On the same thread (http://forum.xda-developers.com/showthread.php?t=1568792) i have read that there is a way to relock the bootloade. By doing that will i get Track ID back? (i have aloready read somewhere else that DRM cannot get back even after relocking so i am just asking about TrackID)
4) If answer to question n.2 is yes, will i get the warranty back if i relock the bootloader followinf this () procedure?
Thanks in advance to anyone who will help me.

1) Yes, you lose both functionality, but we are unaware, what are DRM keys used for. Original TrackID will not work, but if you install newer version from Market, you will have no problems, so don't worry about that.
2) Yes, warranty is void, but bootloader can be still relocked.
3) Nope, DRM keys are gone forever, about TrackID, I already wrote.
4) Depending on the service shop, if you lock the bootloader, they will likely not check, if it has been unlocked or not. Official service shops/manufacturers might go looking for the DRM keys.
Last answer is a opinion, as neither I or anyone else has experience with this, so we are not aware of it. As long as bootloader is locked, we think you will be fine.

Is so much better via testpoint, just my 2 cents

I am sure it is The problem here is that i am totally new to android. I am a total n00b. And since i want to be able to record both ways of a phone call recorder i am obliged to unlock the bootloade and install a modified kernel.

What do you mean by that?
By the way ... i see that you currently have an xperia mini pro sk17i (like the one i am planning to buy) with the rage kernel installed ... how does the phone recording function work? everything's fine? What app are you using?

[Q]Bootloader: What are the advantages and disadvantages of unlocking it?

What are the advantages and disadvantages of unlocking the bootloader?
i'm a little bit confused about this..
i was a former samsung galaxy 5 user.. and i used to have cyanogenmod7.2 on it.. it was easy to flash on samsung phones.. and i knew the risks involved with it..
but can you tell me how different and how this would be a big help? thanks..
Having bootloader "unlocked" allows flashing/use of custom kernels. Custom kernel is needed for advanced firmwares, like cyanogenmod, so having locked bootloader, cm can't be installed.
Still changes in system partition are possible using an exploit to obtain root access to the phone, allowing reasonable system customization (like bloatware removal).
Two ways of bootloader unlock are available - the official one provided by SE web service, where you are forced to agree for voiding the warranty (providing your imei, so they know which phone is to be unlocked). This way access to DRM is lost forever.
And there is unofficial "unlock" way using testpoint shortcut to ground pin, which somehow bypasses signature checks in bootloader and allows kernel with not valid signatures to run (even though bootloader looks like still locked). This way DRM access is kept. It should also be possible to revert this type of unlock and return to stock fw. Unfortunately the testpoint is covered, so using it (even blindly with a needle) might be noticeable if the phone is examined.
now i know that samsung is easier than SE..
anyway, what exactly is DRM and what does it do in our phone? why is it essential? thanks for answering..
DRM (Digital Rights Management) is a "feature" to provide conditional access to media content. It is (was?) used in TrackID application.
Without DRM access (after official bl unlock), TrackID does not work.
It is rumoured that some newer version of trackid does not need drm to work.
In any case, there are alternatives for trackid not needing drm, so it's not really essential.
But losing it is irreversible so it's better to think twice if someone needs it or not or if just wants to keep the phone in "a bit more unaltered state".
so it's just for music? or media content means for all types of media? like images, videos and music?
what units does not lose the DRM? i just bought mine.. but i think it has a firmware build of A.0.42.. sony ericsson is really different on how samsung phones work.. oh my..
In general, DRM may be used to manage conditional access to nearly any content.
Currently I know only about trackid that needs it in xperia phones (never used it though and not sure about any other stock apps as I don't use most of them either, due to needed registration or possible spyware). Purpose of trackid is to record a sample of music around you in order to serve you details about the song played (using internet access).
But in general, it might happen, that in future stock fw update, there might be another new app, that could use DRM originally available, so you could buy music/video whatever... If it's not there already...
Simply it's kind of copy protection.
Without it, you cannot buy/access the protected content.
It's better to avoid using it in my opinion...
so this means it's much safer to have an unlocked bootloader? because DRM does not have any major use anyway?
and how about official firmware releases? will it affect how we update our phones?

safer? what do you mean?
It's about preference. I don't like DRM so wouldn't mind not having it.
On the other hand, there is a way to "unlock" and still keep it (with possibly better chance to keep the warranty as well). But could be more difficult for not experienced person to do it.
If you do not need special kernels, BL unlock is not needed at all.

you will not able to update your phone after bootloader unlocking, though i read on arc section that there is a way, but if I was in your place, I wont take risk if I want to try SE ICS
right, with unlocked bootloader (at least the testpoint way, which I have my own experience with) the update (over the air) bricked it quite badly... I had to re-lock and then it worked again...
Not sure how it is with the official SE unlock way.
But it's possible to update with flashtool after ftf image appears (when someone converts it from official SE update).

It was fixed in latest version of setool (not free s1tool).
now i'm confused.. so getting bootloader unlocked via SE's official way has no way to re-lock it? and i wont get official update?
and what is setool? sorry.. i'm new to SE.. thanks for answering the questions guys.. i'm really learning now..

No, you should just never ever upgrade over the air (via wlan, ota update) and PC Companion/Sony Update Service on your computer won't work anymore. But you are still able to update your apps in the playstore
No unlock bootloader = no custom kernel :highfive:

exactly, you made it sound so simple
after unlocking the bootloader, flashing a prerooted system.img will also work if you don't want a custom kernel.
Finding this should not be that hard: [Xperia S][INFO][REF] All that u need to know before u begin
Oh.. and unlocking the bootloader will also have some disadvantages like warranty and DRM related things.
Still not easy
can you link it step by step plz...
what i have to do first
(little noob)
I have not rooted my phone (yet..) i don't want to unlock bootloader.
I think its best if you start reading from the beginning of the previous link, or if you want to get started right away then:
see this tutorial for Unlocking Bootloader:

Thx man i will try it...
to root i will have to unlock bootloader??
is that really needed?
Arter bootloader i need to unlock also??
Currently it is the only way to root, later on another way will probably come along, but for now you must unlock your bootloader to root your device.
There isn't really much of downside besides losing some functionality in some apps due to the loss of your DRM key. It does not 100% void your warranty, but if you plan on overclocking and it goes wrong, your warranty will probably be voided.

Rooting Xperia S with unlockable bootloader

Hi, I just upgraded from ArcS to Xperia S, and bought a proper sim-free Xperia S. I did the test in the service menu, and it says Bootloader unlock allowed.
Now i'm guessing when you unlock, that you lose DRM keys and other stuff (like the Arc did). I only really want root, without losing anything that I can't get back.
What's the best method? Is unlocking the bootloader the only option open to me?
Thanks.
Hi CrazyPeter
Take a look at this threads:

I don't know if the DRM keys will be deleted or not. But I think while the Bootloader is untouched, the DRM keys also will be left untouched??

Several problems with Xperia Z2 after unlocking bootloader

Hello XDA community,
I have a Xperia Z2, and i unlocked bootloader WITHOUT saving my DRM Keys, (i know shame on me :crying, now i know I did something stupid, nothing to do about it, but since i unlocked, i have had several problems: inestability, it means i am using an app and it restarts, or just closes, or even my phone restarts, if I go to contacts i dont have facebook contacts, the option just dissapeard, it means birthdays dont show in calendar, average camera photos just too noisy or awful photos, xreality not working properly, i know some issues are known but i havent heard about facebook contacts, to be honest i feel really bad with phone like it. So my questions are these, and thank u, thank u who could answer me, just work with me I know a little of these world, so if u could be a little specific about instructions or solutions i would really appreciate it:
1) Having an unlocked bootloader phone, in terms of security, is it easier to hackers to mess up my phone?
2) Is it better to lock my bootloader, if so, how can i do it, resolving my issues and not losing features?
3) If unlocked bootloader is an option, how can i have my phone back, i mean without issues? ( I read a thread about this point, but i confuse a little, because i dont have recovery or rooted)
I tried installing an ftf from flashtool, issues still there =(
Thank your for ur patience.
God bless u.

Hmm technically yes. I guess it would be detrimental if someone grabs your phone and flash's a hacked boot.img. Root on your phone is more of a risk with an internet based attack or corrupt apk.

You can lock your bootloader but it won't fix your issues as you've lost your drm keys. There is a drm fix in the cross development section I think. Google "Xperia drm fix xda". Not sure if this will fix your Facebook issue though, I've never heard of that one. To relock your bootloader google "Xperia relock bootloader xda"

Firstly, if you don't have recovery or root, why unlock your bootloader? Thats sort of the point.
Since you lost your drm keys, the best thing you can do is flash a stock ftf file, apply the drm fix and relock your bootloader. It will never be 100 percent the way it was as you can't reapply your drm keys.

Help about bootloader

What will I loose if I unlocked my bootloader? Is there way to root without unlocking it? Or its still not possible? Any alternatives so that I will not loose any important features in my Xperia z5c? I'd like to use my Xperia z5c in full customization. Thank you in advance for answering.
Almost nothing, practically all custom kernels come with a DRM fix. (Normally you would lose some extra Sony features in sound, camera)
The only thing is, you won't be able to restore it. There is no way of rooting without unlocking your bootloader.

Sony warns you that unlocking BL voids your warranty.
But I've send in my phone after unlock BL and got a new one without any issues.
I would recommend to flash stock rom before you send it in for warranty.
Better is hard to say, it depends on what you want to do. If you want root access you'll have no other choice.
