what i will lose with opening boot loader ? As htc said (Some content on your device may also be invalidated and cannot be accessed any more because of invalid DRM security keys. )
i have Sony xperia arc i lost the access to the like button and more
what i will lose in the htc ?
I don't know what to say.I haven't noticed any "loses" after unlocking the bootloader but i seriously doubt that you will lose somethig with the HTC.

When 2.3.4 will be here, i think i need to restore all applications that are preinstalled, yes?
The last time went from 2.3.3 to 2.3.3 build 4 i had to flash back to uk generic 2.3.2, gingerbreak and go all the way up again. Also, i had to remove my user data because the screen wasnt responsive because of diffrend settings.
This makes me a very sad panda.
Can anyone tell me if i will be able enable the OTA process by restoring system apps?
Or might it be a better idea to unlock the bootlocker? But then again, is this really worth it? Isnt this a lot of stuff i have to go through? (will i lose my user data? what are the advantages of unlocking the bootlocker and the disadvantages?)
Thanks in advance, as you can see i have quite a lot of questions.
Ya unfortunately you'll have to restore the system apps if you want to OTA update as it checks. As for unlocking your bootloader, if you can do it I would recommend it. Reason being is that once you do you'll never have to worry about losing all your data again (not to mention the ability to overclock and run CM7) as you will always be able to be easily rooted making backing things up/restoring a cinch (either through a nandroid backup or titanium). That being said the SE way of unlocking your bootloader WILL wipe your userdata, as for the paid solutions Im not so sure. And as a disadvantage to the unlocked bootloader SE says it MAY void your warrenty, also you will loose TrackID as it deletes your DRM certs, however I think the paid solution avoids this.

What is TrackID and what are the DRM certs for? I have been wondering this, since the Sony Ericsson unlock page says it will damage the DRM keys.

I'm mainly concerned if all the Playstation functionality will still be accessible (don't want to take the Playstation out of "Playstation Phone"... then it'd just be "Phone" >_>)
From what I have read, users like Alejandrissimo and Jinx13 provide a service by which they use the SETool on your computer (remotely connected to their dongle, which functions as a smart card to enable the SETool software), to unlock your phone without damaging the DRM keys. Which again, really has me wondering what the DRM keys are for...
So if anyone can provide details on the DRM keys and what they are for and what they will break if damaged, etc., that would be very helpful!
I don't currently have an Xperia Play, but am now strongly considering getting one, since I'm on AT&T and there's a nice blue AT&T version out now... So if anyone can verify the success of the SE unlock method on the AT&T version, that would be good to know too... I have read that the remote unlock method via Alejandrissimo has worked for AT&T users.

The DRM keys have nothing to do with playstation. They manage the digial rights of sony media, so you will loose Track ID. You will loose the ability to "facebook like" media you are playing in the stock music player. and you will loose the ability to purchase music and videos from the sony qriocity store. Afaik thats about it.
The se unlock method doesn't work. Att is carrier locked.

Hi all.
I have recently noticed that my touch analogue sticks on my play don't work anymore, and I have contacted Sony and have to send it in for repair.
The thing is I have 2.3.3 with root and boot loader unlock. I was wandering could I flash stock firmware and relock the bootloader with blagus' method and get the phone repaired without Sony knowing what I did? I don't want to have my phone returned having to pay a fee with no repair done because they know what I have been doing and have voided my warranty XD
That's what i would do, not to say they won't notice. The like button in the music app is gone and trackID won't work cuz the DRM certificates has been deleted. Unless you unlucked it through @Alejandrissimo, then i don't think it's noticeble cuz that way the DRM certificates hasen't been deleted
They might store all the IMEI no used for making an unlock key on their web page to compare with (dunno if that's legal at all, just a thought).

Firstly can you tell me where you bought your device from and if it was brand new or used.
Apart from that the answer is that the difference between a locked and unlocked bootloader is a locked bootloader doesn't give you the ability to root your android device or install custom roms(custom android versions) while on the other hand, if you have a unlocked bootloader you are able to root, install custom roms and basically just modify your android phone. Although there are catches of unlocking the bootloader such as:
You will loose DRM content
You will loose some fuctionalities of your phone that are carrier specific
You will not be able to PROPERLY re-lock the bootloader in case you are thinking of doing that it is possible but you still cannot recover the lost DRM content
You will loose the ability to do FOTA(firmware-over-the-air)upgrades.
That is basically what you will not be able to do.
Although, in my opinion i recommend not unlocking the bootloader yet because the stock android on the phone is brilliant as well as that in the beginnig of April we will be getting the ICS update for our phones which would include nice features like face unlock improved camera app and other major changes which will be good. So i think it is better to wait till then rather than jumping the ship
If you were wondering it is safe to sim unlock your phone(if its locked to a specific network) since you will not loose any functionality of your device. I recommend rooting only if you are going to overclock your device or don't like how it runs if that's not the case then i don't think you should.
You don't need to unlock the bootloader to root your phone and rooting it has no effect on whether you can upgrade or not. If you don't root it you're very limited in what you can tweak and virtually everything on this forum relies on it.
Unlocking the bootloader is only necessary to change roms to cm7, miui etc

i want to unlock Sony ericson xperia pro (mk16i) to install custom roms
But i m worried about warranty issue...
Is relocking boot loader of my device Mk16i recovers warranty???...
you can unlock your bootloader by 2 methods
1)doing it thru official sony website
2)test point method...
when done using official sony website, you lose your drm keys(useless) but thru test point method you dont lose those..however, relocking bootloader can only be done on sony unlocked bootloaders to gain your warranty back.....
hit thanks if i helped.

First of all Many many Thanx for reply, Because i was waiting for reply many hours...
Actually i have unlocked xperia pro boot loader without any safety knownlodge but know i relise...
So relocking bootloader will back warranty again??ARE U 100% SURE????
is there any danger from deleting drm files to warranty?
i m going to hit thanx button on ur reply, please reply fast
see drm keys are used only for stupid purposes like trackid and othr utterly useless stuff drm keys never cause problems for warranty because people who use their phones normally can also lose those drm keys...
and yes, relocking a bootloader will give you back your warranty(thanks to sony who does not keep a record of unlocked bootloader phone's imei number)
but remember that relocking can only be done on bootloders that are unlocked using the official method...
I decided to unlock it, then im stuck in bootloop... At first it says failed, then after i press it again, it says succrss, but i got a bootloop...

When you unlock the bootloader via sony's official way (using fastboot mode) your security related contents (DRM keys) in trim/TA partition gets erased and you will have access to install a new custom rom . But while unlocking is under progress, say for any reason it gets interrupted,there is a chance that all security related data might not be erased fully / In other words there is a chance that TA partition might have been corrupted
Usually when your phone boots its verifies for the intactness of TA/Trim partition, either it should have all security data (locked bootloader) or fully erased security related data (unlocked bootloader), if partial security information is available, it considers that TA partition has been tampered and will refuse to boot

Right now if you are able to boot into your phone, leave it, you have already unlocked/relocked it. If you are in the same situation again,
Steps
1) Relock your bootloader via flashtool
2) Now flash a fully bundled sony official ftf via flashtool.(This will ensure that if any discrepencies in TA partition are there, will be corrected)
Note: This will not restore your DRM keys.I am afraid if you have not backed up your DRM keys during first unlocking trail.they are lost.
3) Follow sony's official bootloader unlock method (www.developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader)

Good that you had a TA backup before unlocking.If you restore your TA backup and unlock it again , it will again erase your security keys, which will lead you to where you started.What is your requirement . Unlock your bootloader only if you want to install a custom rom. Believe me, TA partition is not the one to be played with; it can even render your mobile into a costly paper weight(hardbrick), if it gets messed up pretty bad . If you are already unlocked do not try to restore your TA partition,and unlock again.Its already unlocked and doesnt make any sense to unlock it again ; Restore it only when you want to go back to a locked bootloader.
