Unlocking bootloader from Live with Walkman

[Maxxd01]

I researched about the matter, and reached some conclusions:

- I don't want to use the TEST POINTER method, I really don't care about OTA updates or Track ID app (as far as I know there are no more consequences), Shazam and Soundhound do the same

- I would like to unlock the bootloader in some manner that, if I need to relock the warranty will still be valid (same goes for root, but I guess flashing an original firmware unroots the device)

That said, found the official instructions to unlock the BL, but still have the main question: is it the procedure completely reversible? Also, is it free?

Thanks in advance. Also really appreciate if someone corrects something wrong I said.

you can still relock your bootloader and receive official sony updates, but the problem is, you loose DRM(in which if sony finds out, you still lose warranty).

i found this thread and said that DRM cannot be restored :/

I don't know about non free relocking if it will be able to restore DRM though.

oh and by the way, this thread provides the easiest way to unlock and relock your bootloader for free.

goodluck and enjoy

DRM cannot be restored at all.
Install TrackID from market and it will work.
Bootloader can be relocked, doesn't matter how you unlocked.
And yes, it is free.

Ok, so I suppose the DRM Keys only affect the OTA updates (how should we care if we are unlocking BL for custom ROMs

So, I suppose if I have a problem on my Live (but it still turns on), I apply an OFW and then relock it, it's a matter of luck if the techical assistance is going to check if the DRM is still valid or not.

What method do you advice to unlock the BL?

Method, pick which is better for you. I used official method, no messing with cables.

Unlock it the way you prefer to it does not matter it will lose warranty any way it is just luck if they will check it or not at the service center. Any way it is really hard to completely brick your phone unless you don't know what you are doing. The main difference is with the test point method you are able to update using seus without problems and it looks more complicated than it really is I only used a clip

 

[melander]

just a question about unlocking thru official method.
since you would have to get the unlock key directly from Sony.
would they be able to track your phone since you will be giving them some details like your name, IMEI, email etc. to get the unlock code?
do the service centers have access to that database?

 

[Someguyfromhell]

There are no Sony Mobile Service Centers, phones need to be taken back to shop and they use service of specific mobile repair shop.
Depending on what reason you need to take it back, they might want to check it or not. No one has so far done this, so we have no information.

What is DRM and Track ID ?

I want to unlock bootloader my phone, but I am still confused, what is the risk of a official bootloader from sony ? What is DRM and Track ID ? what is its usefulness for wt19i?

sorry my english is not good

There is no risk either way the difference is that with the official method you will lose your drm (Digital rights management) and the official support of track id (the app from se that you use to search for the info of a song playing in the radio or the tv etc.) meanwhile using the test point method you will not lose them. If you want to install a custom rom like cm9 or miui you need to unlock your bootloader to be able to flash the custom kernels those roms need.

can you save DRM with CWM backup before unlocking bootloader?

Nope, DRM is not saved in CWM backup.

Thanks in advance for all helpfull answers.

I just want to understand the following. Some Live's come with "unlock bootloader allowed"="no" others ="yes". What does that means and more important: what are the implications?

I cannot understand the difference because as fair as I understand right now, all live's (branded/sim unlocked or not) are unlockable (referring to bootloader).

When they come with boot loader unlock : no it is a branded sim locked phone in which case you can unlock bootloader but you will have no access to fastboot meaning you are unable to flash a custom kernel, also there will be no way you can officially unlock the bootloader so will have to use the test point method and of course you will need to pay to fully unlock your phone to be able to access fastboot and flash custom kernels.

Did I miss something??

So, for sim locked branded phones ("no")

- To unlock the bootloader: test point method
- Access fastboot: use (and pay) through wotan server

Am I right? I never though that was two different problems.

I'm not really sure about Wotan server however I'm pretty sure about setool and omnius and if you are willing to pay the phone will be fully unlocked (bootloader, sim and fastboot) with one procedure using the test point method.

So, I'm curious, if I have branded sim lock Live ("no" bootloader) can I install an original firmware without using an official channel? Do I need fastboot access?

I'm asking because I'm almost sure that my carrier will not update the Live to 4.0, so I suppose I have to use some other tool in order to install it.

you can debrand (install a generic firmware) your phone using wotan server for free and as i know it will also change your product code so next time and official sony update is available your phone will get it.
