How do we find out if my V is unlocked?
[Sony Xperia T, TL, TX, V] NuriJ:
If you haven't unlocked it.. Then it's most probably locked :)
[Sony Xperia T, TL, TX, V] cire1980:
I mean, I've already done all the steps, and it appeared to be successful. But where in the phone could we see that the bootloader is unlocked?
[Sony Xperia T, TL, TX, V] cs098:
well if you think it's unlocked, try flashing a ROM and a kernel, if it works, its unlocked, if doesn't then tough luck :)

....And when unlocked, did Mobile Bravia Engine 2 still works? Try to BE off then make a screenshot, the same goes to when BE is on. Make a comparison. This is a known bug for 2012 Xperia phones. Did Xperia V included?
[Sony Xperia T, TL, TX, V] Darkfunnyguy:
SlenderMan,

I urged you to edit your thread to warn people if they decide to unlock the bootloader of their Xperia V smartphone. On my Walkman app you will get a security error when trying download music info. Yet I tried fixing but to no avail by using this thread:-

http://xdaforums.com/showthread.php?t=2006356

Also tried this :-

1.Move CredentialManagerService.apk from /system/app to your SD card.

2.Reboot your phone.

3.Move back CredentialManagerService.apk from SD card to /system/app

4.Change permissions to rw-r-r

5.Reboot your phone.

But still unsuccessful. I used the playerpro app anyway but to let you know this will happen to smartphone if they choose to unlock their bootloader.

I think my Mobile Bravia Engine 2 is fine but it broke the download music info using the walkman app.

Did you enable Fastboot? Volume up and connect USB cord.
[Sony Xperia T, TL, TX, V] -SlenderMan-:
1: Make sure you connect correctly - Hold Vol. Up and Plug In

2: Make sure you have drivers installed correctly - Search at Start Menu -> Device Manager

Is it 100% impossible to unlock the phone?

Is there no other way? :(

Because I really need to use a different SIM on my phone.
[Sony Xperia T, TL, TX, V] -SlenderMan-:
I think there's a way. By using testpoints. But i'm not sure if it's available for the V
[Sony Xperia T, TL, TX, V] pow3rflow3r:
I got some troubles in step 7&8.

I switch the phone off.

I push and hold the volume up button to enter "fastboot".

The blue LED will turn on and then the first time I got a message that drivers where missing and I closed that message.

But then the blue LED turned off and I only can find "Sony USB storage" in my device manager.

I tried it several times again and now every time I enter "fastboot" the blue LED will only stay on for about 10 seconds.

I can not find the device (S1_fastboot or Android Phone) fast enough before the blue LED turns off and then I can only find again the "Sony USB storage" device.

Deleted the drivers of the device "Sony USB storage", but then after I enter fastboot (blue LED turns on) and the blue LED turns off again it will automatically install these drivers again (because I suppose as soon as the blue LED turns off I leave the "fastboot" mode).

Any suggestions anybody.

Please advice.

---------- Post added at 02:48 PM ---------- Previous post was at 01:50 PM ----------

Ok it worked. I just had 10 seconds to install the driver as long as fastboot was "activated" (blue LED was on).

I had to do this in 3 times.

First to see in device manager where the device would appear (S1 fastboot).

Then to "right click" the device and select install driver. Select the driver folder.

Then again in fastboot and installed driver.

Weird? Everything that didn't work for you worked for me with unlocked bootloader.
[Sony Xperia T, TL, TX, V] paulieboy2112:
Hallo!

I can't seem to get it working.

My phone is branded (italian Tim), still System info/Configuration tells me it can be unlocked.

I intalled the driver as explained and the phone connects correctly in fastboot mode (light turns blue and fastboot tells me I'm using version 0.5, so I guess it's allright).

But when I do:

fastboot.exe -i 0x0fce oem unlock 0x16516C**********

I get:

<bootloader> Unlock phone requested
FAILED <remote: oem unlock failed!>
finished. total time: 0,056s

What am I missing/doing wrong??

Thanks.
[Sony Xperia T, TL, TX, V] Erica Law:
Hmm. I've faced that before and my problem was I typed my code wrongly. Try again?
[Sony Xperia T, TL, TX, V] paulieboy2112:
Tried several times, still no dice.

Maybe my phone, since is branded, just can't be unlocked even if it says it can be..at this point I don't know what to think.

Thanks anyway, Erica..
[Sony Xperia T, TL, TX, V] Erica Law:
I got the problem again! I found a solution. Get another code from Sony. I typed my IMEI wrongly and got the wrong code.
[Sony Xperia T, TL, TX, V] paulieboy2112:
No way.

My IMEI is 335101050336707

I enter: 33510105033670 (14 numbers as requested) in the website.

I get: 16516C86D25C5456 in my mail

I type: fastboot.exe -i 0x0fce oem unlock 0x16516C86D25C5456

I get the same error.
[Sony Xperia T, TL, TX, V] Erica Law:
Too much info lol. That was suppose to be private. Try entering your IMEI number again. This time just be careful. You may get a different code like I did.
[Sony Xperia T, TL, TX, V] NuriJ:
Do you use fastboot.exe from the android sdk?
[Sony Xperia T, TL, TX, V] paulieboy2112:
Used the files from this thread and tried even on archlinux getting fastboot from the aur...same result.

The only thing I obtained till now is debranding, by flashing the stock firmware.

Since what I really am interested in is root access, I'm gonna try getting it today without unlocking: I've seen that there's way for the xperia Z that seems to work even for the V on JB...

I've heard that unlocking is samewhat bad adviced (maybe something about losing bravia engine, is that true?)
[Sony Xperia T, TL, TX, V] androbie:
My xperia v bootloader is unlocked and everything work fine so far
[Sony Xperia T, TL, TX, V] alfanumerica:
Usually unlocking bootloader disable the ability to use TrackID and Bravia Engine but on the forum there's a solution for both problems.

But with tim unless you've got some friend at the shop you can forget about warranty service if you unlock your device.

[Sony Xperia T, TL, TX, V] bodega1968:
slenderman,

wonderful instructional detail. but one thing i kindda got lost with the thread: when checking bootloader status allowed, (1) does a NO mean that your method cannot be applied? (2) even with a NO STATUS, can the KEY that one gets from SONY still work using your method?

just clarifying since i plan to compile helpful instructions all for XEPERIA V, from rooting, to unlocking and even swapping the SD and Internal memories. But only the ones that have been tested and working.

awaiting your expert resply,

thanks for your time dude...

[Sony Xperia T, TL, TX, V] davidtkf88:
If your bootloader status is showing NO, then it mean you cannot unlock it. you can still get the key form SONY, but you will fail after you enter fastboot.exe -i 0x0fce oem unlock 0xKEY. hope that help:)

---------- Post added at 10:23 PM ---------- Previous post was at 10:15 PM ----------

To unlock your phone, the easiest way is use flashtool for Sony, just connect your phone to your computer with android debugging enable and hit BLU button, then follow the screen, you will easily unlock your bootloader. Just to make sure you can unlock your bootloader, dial *#*#7378423#*#* in dial screen, you should enter sony service menu, from service menu, go to service info>configuration you should see your bootloader unlock status, if it show YES, then you can unlock, if NO, then you are stuck with your stock rom..:)
[Sony Xperia T, TL, TX, V] bodega1968:
thanks so much dude!

i guess then, it can only be unlocked via 'hardware' methods... which i've seen in some websites. so 'locked-in' users will just have to be patient, and when their contract is over, then perhaps, they can unlock the bootloader via 'hardware' procedures and install their desired custom ROMs. thanks once again.

Stuck

Im stuck at STEP 11- Step 11: Here is the important part. Type these commands to unlock your bootloader!

Quote:

1: Type in fastboot.exe -i 0x0fce getvar version

2: It should return a value like “0.5”. This ensures that your device is correctly connected

3: Now type in fastboot.exe -i 0x0fce oem unlock 0xKEY

Important! Remember the code you recieved? Replace KEY with that

when i type in fastboot.exe -i 0x0fce getvar version

i get "fastboot.exe" is not a recognized as an external or internal command, operable program or batch file.
[Sony Xperia T, TL, TX, V] vrl13:
Try to navigate to the directory where fastboot.exe is stored (use CD) in command prompt like this:

C:\> cd c:\users\yourusername\desktop\fastbootdirectory

Then run your command.

You are seeing this error because windows is unaware of the fastboot.exe location until you add it to your PATH variable.

Alternatively you can specify the complete path within the command line:

C:\completepath\fastboot.exe -i 0x0fce getvar version

Good luck!

Error found on step 10.

[Sony Xperia T, TL, TX, V] bodega1968:
Dude Schuan,

Thanks a million for the tip!!! I wasn’t expecting any follow up on my query on how to unlock this enigmatic bootloader of Xperia V. I believe the steps you have just outlined will work seamlessly, however, my case may be a bit different.

I have long since looked for a solution, but I believe there isn’t a ‘soft’ approach to my problem. It concerns unlocking a bootloader for a device that indicates that the hardware does not allow one to unlock the BL.

One can find this out by typing *#*#7378423#*#* (*The numbers actually form the word ‘SERVICE’, neat!) and once inside, tap “Service info>Configuration>Rooting Status” if the “Bootloader unlock allowed” states YES, then I believe your instructions will be valuable to many users. If, however, it states NO, then I think there’s nothing one can do to unlock your Xperia device bootloader, except through some ‘hardware approach’ that changes this status using brute force (i.e. wires, short-circuting some contact points by opening the back of the phone, etc. – this I believe is available for some devices, not yet for the V)

Anyways, I haven’t really looked into your procedures. But unless there are new developments on SONY’s side, on unlocking the BL with a soft approach, then I’m ready to try it out. But if this trails off to the usual SONY website that I’ve been to, then I guess I may have to wait, or simply be content with my stock ROM, sob, sob, sob.

Thanks a again!

bod1968

p.s. will get back to you on how things may work out... thanks a million again.
[Sony Xperia T, TL, TX, V] bodega1968:
dear all,

maybe it would be good to notify readers (Ahead of time, before they even click on the SONY website, this NOTICE:

Please note! It will only be possible to unlock the boot loader for certain releases. You can check if it is possible to unlock the boot loader of your device in the service menu by following the steps below:

In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.

Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing,

your device cannot be unlocked

.

sadly, it seems that there is no way to go around this... i'm only curious why this setup is in some devices and in others not... strange!!! ;-(
