You must be kidding...

Simply follow this (link already given in first post):

http://unlockbootloader.sonymobile.com/instructions

Same as above... did you ever use fastboot?

First check if the green LED is active (you entered fastboot mode on your phone, did you?).

Install drivers on your host, connect your phone, check with the command: fastboot devices

Nope... have you asked your carrier for SIM-unlock code?

xxx,

this link is expired.. no multiupload available.

And I've got some problems with installing adb driver.. It shows that he find the driver, but he says he can't install it. it is saying: no microsoft certificates found.

I'm using windows 8 Pro x64. (maybe they got new driver requirements?)

thanks.

Arc S Unlocking Bootloader.

Hello, I've been having issues trying to unlock my Arc S.

I've followed the instructions, checked that my phone was capable of being unlocked, gotten a code from Sony, and successfully installed the adb drivers, the phone's LED was blue, and I opened command prompt in the folder containg the fastboot.exe.

However, when it came to to using the getvar command, I ended up getting <command write failed<unknown error>>,

I tried anyway, to unlock, and I got the same thing.

I've been searching around, tried different drivers, but to no avail.
[Xperia Arc General] Kajendran:
I managed to unlock my bootloader long time ago and i have flashed custom kernals before and had no problems...

yesterday i reflashed the 4.0.4 ftf and rotted it... All seemed to be well...

UNTIL.......

WHEN I FLASHED A CUSTOM KERNAL..... ALL KERNAL RELATED APPS SUCH AS CAMERA JUST DISAPEARED.....

SO BY RELOCKING AND UNLOCKING THE BOOTLOADER AGAIN BY THE SAME METHOD.... CAN I MAKE THE KERNALS WORK PROPERLY.........???????

DOES THIS METHOD FORMATES THE BOTTLOADING PARTITION AND THEN FLASHES IT OR SIMPLY OVERITES THE EXISTING PARTITION..????

[Xperia Arc General] Cordovan Splotch:
I've been trying to do this for a while now with my new ST17i Xperia Active, but in the cmd prompt when I enter "fastboot.exe -i 0x0fce getvar version" it just tells me that fastboot.exe isn't a recognized internal or external command. I'm guessing this means it can't find the fastboot.exe file since there is no such file in the designated folder.

I've been looking around but I can't find any files online or off that I'm sure enough is the right one to get and put in there.

Do any of you know where to get the right fastboot.exe file?

[Xperia Arc General] bloomer2011:
oem unlock failed

It would be really great if the OP could add in additional points:

* the need to type the KEY in CAPS. If you don't, you'll probably get "oem unlock failed" message.

---------- Post added at 09:34 PM ---------- Previous post was at 09:26 PM ----------

Oh, and I forgot also to mention:

* in Windows 7, if your computer can't find or doesn't recognise the driver file while following the Sony instructions, find the device in Device Manager, choose to update driver, then browse for software > pick from a list of devices > have disk > find the driver file. You will probably need to agree to accept that the file is unsigned and is a security risk.

(I know this sequence is mentioned in varying clarity in different places, but it's good to have it in this thread... certainly would have helped me :silly: )

Not working

I can not get my bootloader unlocked.

My first problem was that I couldn't download the files from this post or the extended "android soul" tutorial. However, I downloaded the files instead from the sony website tutorial (Android SDK manager and the winusb thing).

The problem is, I have followed the sony tutorial and it says that when I connect the phone in fastboot mode it will automatically ask for drivers, which it doesn't. Therefore, I followed the "android soul" tutorial to open device manager, right click S1Fastboot, update drivers, and then I pointed it to the folder with the winusb thing in it and it doesn't recognise any drivers in this folder. I originally pointed it at the google usb drivers folder but have also tried moving the winusb file to other folders, all of which fails. Can someone please tell me where I have gone wrong?
[Xperia Arc General] LeBoy:

Thank you for this guide
[Xperia Arc General] Someguyfromhell:
Most likely your fastboot is locked/disabled and you can not unlock the bootloader with this method. If your phone is manufactured before 12W11 (check it under the battery), you can unlock bootloader by test point method. If after 12W11, then you can't unlock your bootloader at all.

Open Phone/Dialer app, go into service menu (enter *#*#7378423#*#* on the dialpad), Service Settings->Configuration (if I remember correctly). What does it say after Bootloader Unlock Allowed?
