Relocking bootloader?

The link for downloading the ftf file for relocking bootloader is broken.... wanna relock bootloader in my xperia s... can someone post a mirror?
[Sony Xperia S, Acro S, Ion] HooLIMAN87:
[MENTION=2784807]DooMLoRD[/MENTION] do you still have ftf for relock xperia s bootloader? If you do can you upload.

Tnx in advance.
[Sony Xperia S, Acro S, Ion] someone755:
If you guys would have posted three days ago, I would've had it.

Damn you, Murphy's law!
[Sony Xperia S, Acro S, Ion] HooLIMAN87:
I also had it, but needed to reinstall system on pc (thought that i saved it, but i was wrong) so i deleted it with windows. :)
[Sony Xperia S, Acro S, Ion] akhi24nick:
Never mind.... The latest flashtool allows u to relock natively :)
[Sony Xperia S, Acro S, Ion] someone755:
Okay, but does it work?
[Sony Xperia S, Acro S, Ion] -PiLoT-:
I still find it odd this hasnt been brute forced yet. like it was for the x10
[Sony Xperia S, Acro S, Ion] jnsanders:
When I try to use the BLRelock on Flashtool it says:

ERROR - ERR_SEVERITY="MAJOR";ERR_CODE="0019";ERR_DYNAMIC="SIN header verification failed";.

Does anyone know where I can get my hands on the FTF to relock an Acro S or S?

Edit:

Fixed!! Came accross the kernel, saved my phone. Good luck to all.
[Sony Xperia S, Acro S, Ion] someone755:
[MENTION=790084]-PiLoT-[/MENTION] what do you mean by that, 'brute forced'? o.O No sarcasm intended, this is my first Sony phone... [MENTION=4234955]jnsanders[/MENTION] did you try looking inside the flashtool instalation folder? There's gotta be some file in there that would relock the BL.

I'll download the latest FT anyways, I need to RMA something :P

Will post a link if I find the file :D
[Sony Xperia S, Acro S, Ion] -PiLoT-:
Well brute force isnt exactly the word im looking for. on the X10 someone found a vulnerability in to SoC. and those with locked bootloaders could unlock anyway
[Sony Xperia S, Acro S, Ion] jnsanders:
Actually, I never had to open that folder. Someone shared this link with me: https://www.dropbox.com/s/ts1khhal3e...bootloader.ftf

I flashed that using Flashtool and successfully relocked my bootloader, then used PC Companion to do a fresh install of stock Firmware, charged overnight, and my phone is FIXED!!! WOOO!!! It says it's for Xperia S, but it works for Acro S also. Thanx for your suggestion tho!
[Sony Xperia S, Acro S, Ion] someone755:
Oh, you mean the 'put a pin on one of the testpins and unlock it like that' method? The Testpin method?

Well, the Nozomi's testpins are hidden, so there isn't much point in that... Though it would still be cool to see that :P
[Sony Xperia S, Acro S, Ion] -PiLoT-:
no... someone found a vulnerability in the bootloader ecryption for that chipset
[Sony Xperia S, Acro S, Ion] someone755:
Oh, well...

For our chipset, wouldn't this have been found way back in 2011 on all of those HTC phones?

Just a guess...

Also, back in those days, I feel like there was much more open-ness from Qualcomm, since the phones with Snapdragon S1s were the best thing to develop on. Just personal opinion here.
[Sony Xperia S, Acro S, Ion] joelrwise:
I can confirm that this works for the Xperia Z Ultra. Thanks dude.
[Sony Xperia S, Acro S, Ion] georgesmh:
hey im having a problem.. i don't know if anyone had it and posted it here.. when i enter fastboot mode it stays only for like 5 seconds, then sony logo appears and fastboot mode is off.

i tried both xperia S and acro S, on 2 different laptops , win 8 and win 7, both 64 bit

what do i do?
[Sony Xperia S, Acro S, Ion] someone755:
Yes, it's already been asked. Many times.

Mostly, it's resloved by reinstalling the drivers. If Flashtool's drivers don't work, install them manually.
[Sony Xperia S, Acro S, Ion] Rendering:
Hi, I am trying to unlock an ARC S with

./fastboot -i 0x0fce oem unlock KEY_FROM_SONY

but I obtain

(bootloader) Unlock phone requested
FAILED (remote: oem unlock 0xFFFFFFFFFFFFFFFF)
finished. total time: 0.002s

What could it be the problem? I searched on the internet but I did not find the problem. The moment I entered the IMEI on Sony website, I had to trim the last char (as suggested on the site) because it was too long. Could it be the origin of the trouble?
[Sony Xperia S, Acro S, Ion] Gallardo994:
Are you serious? KEY_FROM_SONY has to be replaced with the actual key

Powered by GSR with Android 4.1.2 on the board.

[Sony Xperia S, Acro S, Ion] someone755:
If you really want drivers and fastboot and adb, I have something like that in my signature (browse the attachments, it's there). But it's a bit old, so adb won't work with Android 4.2+.

OR, Google 'Flashtool drivers' and download that. (But you'll still need fastboot and adb.)

IF you just want Fastboot and ADB, Google 'Minimal ADB and Fastboot' and install that.

use latest flashtool and use the BLU button to unlock/lock/relock bootloader ;)
[Sony Xperia S, Acro S, Ion] Sli2cooL:
Maybe this question was already answered, what if i try to unlock my bootloader even if the the *#*# menu says no, would it damage my phone or it just wont work? Do i have to go to the company where i got the phone disable that lock to unlock my bootloader? It's a Xperia U by the way thanks for helping. and sorry for poor grammer xd.
[Sony Xperia S, Acro S, Ion] someone755:
Yes, your best bet is to go to the operator people and ask them to unlock it. If they refuse, you could try going to a workshop where they'll unlock the SIM for you, but that's not guaranteed to make your BL unlockable.

Really, nothing should happen if doing this, because it's locked and fastboot can't send the command to a phone that denies the command.
[Sony Xperia S, Acro S, Ion] Sli2cooL:
Yeah mi phones is already sim freeg gotta go to the company :s thx for the help!

Check your USB cable, try different USB ports.

If all else fails, try another PC, and in the end, another method (FlashTool, for example).
[Sony Xperia S, Acro S, Ion] jackxperiap:
Does unlocking bootloader itself wipes data?? I have got the key from Sony to unlock bootloader and any easy method available ??

Relocking bootloader

Hi there, you seem to know very good how things work with locking/unlocking bootloaders.

I want to relock so I can flash original rom from sony. To relock bootloader, do I need to flash ICS before starting or I can do it if the phone has JB (i'm using existenz rom and doom's latest kernel)

Thanks in advance!
[Sony Xperia S, Acro S, Ion] someone755:
Usually, it's relock first, then stock FTF flash.

You could flash and then relock, but I've had bad experiences with that.

Can you please post another link for download the fastboot package with usb drivers (alternate drivers if the ones in package dont work)
[Sony Xperia S, Acro S, Ion] WenSes:
Which are the unofficial ways you know to unlock the bootloader? and more important, do you recommend to use this methods?

Enviado desde mi Nexus 7 usando XDA Premium HD app
[Sony Xperia S, Acro S, Ion] someone755:
Question one: If you mean the ADB and Fastboot drivers, I have some old ones stored in a thread here http://xdaforums.com/showthread.php?t=2087337 The Fastboot zip will serve you well in that case, if on Windows.

Question two: The "unofficial" versions are all based on the official one (they all work by the same principle, just masked so you don't see it).

Which one to use? Swift tutorial:

1.The official one. If that doesn't work, you move to

2.The one that looks best to you. And if that doesn't work onto

3.Any other one. If you have enough un-luck for this one to not work

4. Go back to the official one and retrace all your steps! Get the code again, reinstall the drivers, try another PC.
[Sony Xperia S, Acro S, Ion] Sexy Devil:
thanks......

nice tutorial :good:

[Sony Xperia S, Acro S, Ion] neuropass:
Looks like the two download links are not available. Anyone has the drivers links by any chance?

Question, I have the following config:

model: LT26i

android version: 4.1.2

base band: 8660-AAABQOLYM-314010-39

Kernel: 3.4.0+1.0.21100-313065-g1ccebb5-00193-gcbc50fc

build number:6.2.B.1.96

Can I use the procedure safely?
[Sony Xperia S, Acro S, Ion] someone755:
If your device says that your BL is unlockable, yes. If not, you can still try, but you won't get further than "ERROR".

Anyways, I'd recommend you either use Flashtool and unlock from there or get your drivers and Fastboot up and running and do it manually (that's how REAL men do it :P).
[Sony Xperia S, Acro S, Ion] neuropass:
lol tahnks! i'll follow the tutorial and see hot that goes :highfive:

[Sony Xperia S, Acro S, Ion] someone755:
You could be on CM11 and you could do it. Gingerbread, ICS, JB, KK, anything your heart desires, you can relock. Though the phone will only work with official/official-based firmware.

So, I saw that you recommended to try, by entering the data as if it were xperia s, and now i have a code, not sure is my code; the question is, when I execute the command "fastboot -i 0x0fce oem unlock ecc.." if the code is uncorrect, there is the risk of brick, or simply an error message?

How about unofficial ways to unlock the bootloader?

I ask because as I understand it:

1) no unlocked bootloader equals

2) not possible to root?
[Sony Xperia S, Acro S, Ion] Cholek3:
I still can't decide to unlock bootloader or not. Correct me, if I am wrong:

1. Unlocking itself doesn't void the warranty, unless I will damage the phone i.e. by overclocking.

2. Loosing DRM, so TrackID won't work, but SoundHound will anyway. Some other things will NOT work as well.

3. You can install different ROM and kernels, which will not void the warranty, unless you brick a phone.

I am missing anything?
[Sony Xperia S, Acro S, Ion] Ferrum Master:
Yes you are...

Service center CAN charge you additional cost for recovering the mess you've done with opening up the phone... i.e recovering via testpoints, jtag etc...

If the phone is bricked = dead = silent as a winter lake... they cannot prove anything :D.

As far I know never had problems with trackID on unlocked devices, rarely use that stuff... I already know my music stuff and that peace of software doesn't like metalheads anyway...

PS.

I know what I say... believe me...

PSS.
