cannot relock bootloader- xperia neo v

Hello all,

I d like to relock my bootloader to install official android 4 on my Neo V.

I would need some help here, please. I ve tried to download Xperia_Relock_bootloader.ftf and flash tools as well. Flash tool does not recognize my mobile, even I think I have it correctly plugged in (holding right button, connecting to usb, blue light on). I tested this via fastboot, which recognizes it - after command "fastboot.exe -i 0x0fce getvar version" responds with my version. I ve tried to run "fastboot oem lock"- nothing locked, I ve tried "fastboot.exe -i 0x0fce oem lock 0xKEY"-nothing.

Thanks a lot in advance!
[Xperia Arc General] maliceomalice:
Maybe u have not installed the flashtool driver for ur phone. Get inside flashtool folder n get into driver folder and then run the application in the folder. Install which driver that are missing.

After done installing the driver, turn off ur phone,press back button and plug the usb, until green led appear. Then, if ur pc have successfully install the driver, a notification will appear. Then, u can continue locking the BL

I dont think is going to understand how DRM is relevant on the phone with the definition.

What I know is that: with invalid DRM security keys, is not possible to make OTA updates.

[Xperia Arc General] sanke1:
Hi guys.

Newbie here.

I unlocked the bootloader using Sony's official method of my Xperia Mini ST15i. Then I relocked it and I am on official firmware using .62 firmware and SEUS is working as well as over the air update.

Now since last 1-2 days, I want to unlock the bootloader again. But following official guide to unlock, the CMD based commands returns "Waiting for device" . Tried all drivers, reinstalls of Windows, another laptop. Same problem.

What are my options to unlock after re-locking?

I'm trying to lock my bootloader to go back to stock ROM as I need to visit the service center.

I connected my phone to PC and flashtool recognized my phone perfectly fine. When I try to flash the file from first post, everything goes fine till it asks to disconnect the device in flashmode.

I disconnect, power off, press the back button and connect USB. The blue LED comes ON but the flashtool doesn't do any flashing. It only says "device connected in fastboot mode"

Here is the log -

Heeeelllp... relock Xperia S

Noob here...

Downloaded latest Flashtool.

Dowloaded relock "FTF" from http://xdaforums.com/showthread.php?t=1527159 - which isn't actually an FTF, just a zip containing a .sin, a .ta and a meta-inf folder.

Flashtool won't operate with above FTF. Tried to bundle files into FTF but flashtool complains bundle can't contain just a loader...

Downloaded Blagus' TFT file - link on page 1 of this thread.

Tried to flash this TFT but rebooting phone in flashmode (power off, hold vol down + insert USB) causes flashtool to report device not supported - install drivers from drivers folder.

Go to drivers folder and run app. Select Xperia S drivers... They install correctly- no errors.

Go back to flashtool and try to reflash .ftf and flashtool fails with "device not supported" again.

Have a feeling I have to do something with Blagus' FTF AND Doomlord's .sin but I have no idea...

Help?

[Xperia Arc General] mintonz:
the result is not same as default locked condition?

I have a question about bootloader re-locking.

Does the way you developed change the handset back to the default condition or only make analogous situation as the default? (i.e. the result is not same as default locked condition?)
[Xperia Arc General] danyal241:
I am quite new to this I had unlocked my bootloader previously from sony website. Then I decided to relock it and your file to to flash via flashtool>flashmode everything went on smooth. The question I have is really how to boot into cwm I have xparts I can use that to boot into cwm but is there a manual way of booting into it if I mess something up? What I want to do is not have a pc and no xparts to boot into cwm. Do I have to manually flash cwm if so where can I find it and how to I flash it. I know this is a bit off topic but it will be great if anyone can help me.

---------- Post added at 02:55 PM ---------- Previous post was at 02:52 PM ----------

Also can I reunlock through sony website using the same method as before? I have xperia arc s.
[Xperia Arc General] littlejoelgriffo:
The thing about cwm is that one cannot simply flash it by itself. Cwm is usually built into kernels. If you flash a new kernel by the way on stock ICS or GB, you will probably get better performance and battery life along with cwm and a new boot image to replace the Sony one.

However xparts is an exception. It allows you to get cwm on stock.

If you want to manually boot to recovery, the most common way is to on the first sequence of booting up ( on stock its the Sony logo) press the down volume button repeatedly until you enter recovery.

Hot the thanks button if I helped ;)
[Xperia Arc General] danyal241:
Here is where I am confused. Of I get unlocked boot loader again via sony website. Can I simply put advance stock kernal does that have cwm in it? What I am worried about is what happens if I get stuck in a bootloop or sony logo when I flash a custom rom? I wont be able to restore via sues? And will have no means of recovery.
[Xperia Arc General] littlejoelgriffo:
Sorry dude but really I don't have the time to answer all your beginner questions. I can refer you to this:

http://xdaforums.com/showthread.php?t=1653188

And my advice to you is to read up about stock ftf files and where to download.

Good luck :)
[Xperia Arc General] danyal241:
Thanks just needed information as I have been so far good once directed to the right threads thanks
[Xperia Arc General] Ghostfreak NB:
You can't use advanced stock kernel on locked bl!

You can flash only stock kernels on locked bl!

And as for your recovery in case of bootloop, it can't be solved as then the only means to get your phone alive is flashtool and root again and then install cwm via x parts and if you've taken backup,you can restore through cwm!
[Xperia Arc General] danyal241:
So basically if I have unlocked bootloader and I get stuck in bootloop I simply connect the phone and flash .587 firmware? Or do I need some special file thanks for ur help in advance
[Xperia Arc General] Ghostfreak NB:
If you've unlocked bl,just flash a custom kernel! Then you get cwm inside it already! So its bootloop free as you can access recovery still!

And if its locked,the one that you told is the way to go....

But make sure usb debugging is on before flashing!
[Xperia Arc General] danyal241:
Thanks for all your help. I tgink I am on locked. As I had unlocked previously but relocked by flashing. Can u just direct me to a thread which tells me how to flash a kernal? Is the same as flashing the firmware?
[Xperia Arc General] tomn222:
But I have got silly question...

Where I can find stock kernel from Sony? :(
[Xperia Arc General] danyal241:
Search the fourm I saw it listed in an arc guide I am on my cell cant find the link right now but will post it tom
[Xperia Arc General] tomn222:
I mean, is there any difference between branded ARC S and non-branded ARC S kernel? Which of them should i choose :)
[Xperia Arc General] danyal241:
By non branded if you mean custom kernels then yes there are huge differences depending on which kernel you choose. Usually the stock kernels are most stable while custom ones offer more features. It is upto you to decide if u need custom or not I have mostly used stock recently I switched over to doom adv stock kernal which is a bit better battery wise so far. And no other issues... Someone told me about arc knight kernel will be trying that out in a day or 2
[Xperia Arc General] Ghostfreak NB:
If you meant custom kernels by non branded kernels

Then person above me is right!

If you meant by branded arc s phones ie SIM locked phone kernels and non SIM locked phone kernels, they are the same!

There's no difference!
[Xperia Arc General] danyal241:
Haha yea that too. Sorry I get world phones they are always sim unlocked so didnt think of that
[Xperia Arc General] Ghostfreak NB:
Same here....

Mine is always SIM unlocked but just wrote it incase it's what he meant to say!

Re locked Boot-loader Track ID Fixed!

Last week i decide to mess up my phone a bit unlocking the bootloader (official way) and trying a bunch of custom roms and kernels (knowing that stock Track ID will never work again, tested and confirmed never worked) this week i decide to get back to stock ICS and flashed the Lt18i ME&North Africa version 587 on my Lt15i, i rooted, install CWM, i wiped D-kache (only) and install "Walkman for ICS & JB U7.5 by ThilinaC" and download music info worked normal, somehow i hit the stock Track ID icon and it was working normal and recording, i never touch any system stuff using root explorer or changed any stuff permission, perhaps somebody can explain "what happened", why Track ID works now if DRM keys are not in the phone anymore?, Anyway tnx to god i got Stock Track ID working again. Tnx for read and let me apologize for my pathetic English.

[Xperia Arc General] Ghostfreak NB:
:banghead::banghead:

You yourself have quoted that

"this is only for Those Who unlocked bl via OFFICIAL WAY ONLY "

And then,you're asking that sorta question :rolleyes:

For Unofficial Unlocked bl,use Setool option of. "restore "

Also,do not update OTA cos chances of you bricking it are high ,especially for unlocked bl phones

Just use Flashtool to flash stock Rom !

Also good for you regarding your new phone ;)

What is the best method for unlocking and then relocked ?

I need someone who have tried both and 100% sure that they are working .

I don't want to lose warranty.

Thanks guys
[Xperia Arc General] Ghostfreak NB:
If you are concerned with Drm keys,go for testpoint method ie unofficial method

If you don't care about Drm,official is the way to go ..

Both are easy n safe provided you do the thing as its said

N this relock thread is for only officially unlocked bootloader phones

This doesn't work on unofficial method

For testpoint,there's s1 or s2 tool

Using which you can relock bootloader as well ..
[Xperia Arc General] aymnahmd:
Thanks bro, will proceed with testpoint tool which can be relocked
[Xperia Arc General] Ghostfreak NB:
Well,both can be relocked ...
[Xperia Arc General] aymnahmd:
Well, the testpoint seems invasive and dangerous,

So I will use the official easy one

Thanks for you help man.
[Xperia Arc General] DarkStryder:
I actually unlocked through sony page and my phone malfunctioned and I sent it off to sony repair service, and they fixed it under guarantee, all I did was relock with this!
[Xperia Arc General] aymnahmd:
Ok ,thanks friend, you made me more confident.

Will proceed now.
[Xperia Arc General] Callliope:
So , i have the same problem like aymnahmd , i have 1 more year warranty , and i really dont want to lose it , cuz everything can happen .. So , this was a mistake maybe ? Or they just cant find if its unlocked , if you relock with this ?

Edit:After reading 20 pages , still i have doubts , some say that you can repair it under warranty , some say that warranty is voided...
