Hello, I have a SE Neo running 2.3.3, not SIM locked, and I am having the same problem as seven other members have had. I didn't see where any of them got a resolution to their problem.

I get into fastboot with no problem; blue LED appears; all seems fine.

I have the correct drivers and fastboot on WinXP.

I can run fastboot -i 0x0fce getvar version and immediately get a 0.3 in response, so I'm sure that fastboot and the drivers on the PC are communicating with the phone correctly.

I went to the SE website, entered the first 14 digits of my IMEI as directed, got an unlock code, and ran fastboot with my unlock code. I get the message "FAILED: (remote: oem unlock failed!)".

Any ideas?

---------- Post added at 09:55 AM ---------- Previous post was at 09:37 AM ----------

Disregard: I got it to work (like, less than 5 mins after I posted - hate when that happens!).

In case future lurkers are looking for solutions, my mistake was really simple. I followed the original directions exactly right... but didn't have my SIM in the phone at the time. Inserted a valid SIM and all was smooth sailing.

Thanks for making this set of steps so concise!

What is the difference between

unlocking bootloader via oem unlock key

and

SeTools "Testpoint shurtcircuit" unlock

method. (It is free by the way)

As i see from posts, if Arc unlocked by oem key, certificate will be wiped , some kind of applications stops responding and there is no way back.

What if we unlock with SeTool method. What will we loose.
[Xperia Arc General] Jinx13:
You lose nothing by unlocking with setool ;)
[Xperia Arc General] lawgone:
What will I do with the drivers that I downloaded from the OP? Because when I tried to enter fastboot it just displayed "waiting for device". Then on the taskbar there's a notification "drivers not successfully installed" message.

EDIT: I did follow Kapil's tutorial which is also posted in the first page and voila, bootloader now unlocked.

Thanks.

Hi there i`m trying to unlock the bootloader but im getting the same thing over and over again.....

Failed (romote: oem unlock failed)

So whats going on....
[Xperia Arc General] Jinx13:
Recheck your IMEI then...

Recheck it again carefully then

Try it again :)

Not trying to make you look stupid but it can happen :)

Hey assuming you don't have fastboot enabled I can unlock bootloader and sim in one go.

A IMEI code will not enable fastboot.

[Xperia Arc General] KUMAz:
Have you tested this so you know that you can unlock?

1.First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the dialler and enter *#*#7378423#*#* to access the service menu.

2.In your phone, 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.

but it says the IMEI must be exactly 14 characters

but my IMEI has 15 characters

what can i do now
[Xperia Arc General] JJD809:
You drop the last number of your IMEI. Read all the instructions on the Sony website, it tells you to do so...

"Enter you name, email address and the first 14 digits (remove the last digit) of your phone’s IMEI number in the input box. Click Submit. You can view the IMEI number by entering *#06# on your phone."

Hey, Lollylost100, long time no see :P

Anyway, when I do this on my Mini, I get to the "fastboot.exe -i 0x0fce getvar version". It gives "<waiting for device>" instead of response. My SDK and Google drivers are the latest. I'm running Windows XP 32bit.

I've tried to use your drivers, but how do you install them exactly?

And also, I don't have that S1fastboot-whatever in device manager (no "Other" category, too)

And, I can't choose the drivers folder, only subfolders.

Will this work on Windows 8 CP?

Tried it from W8, when plugged in doesn't show the usual "install new software" window, and in device manager, it's the "Unknown device", and it fails to install the drivers.

Will changing the port help? Trying now...

OKAY, changing the port and Windows helped!

---------- Post added at 11:27 PM ---------- Previous post was at 10:37 PM ----------

Okay, now I have THIS problem ...

I've tried couple of times, when retreving the unlock code I put 14-digit IMEI etc.

What should I do?

Okay, n00b mistake, wrong code...<

Okay, bootloader unlocked, let's get this party started! LOL

Ok so I rooted my lt15i easily enough. But want to unlock bootloader. When I check the services it says bootloader unlock allowed: no

What's the next step because im not paying for setool or for jinx13 to do it as i dont think that paying for this when using open source software is acceptable.
[Xperia Arc General] Jinx13:
Lol is that right?? SeTool is not open source it requires special hardware to run it.

There is no free methods to enable fastboot on your phone at this time ;)

Many people think it is acceptable and it all depends how desperate people are to get more out of there phone.

That is why most people are prepared to pay for services...

If your not then that is ok that is your gripe and you will have to wait and see if a free solution becomes available

[Xperia Arc General] ttherengreek:
hi there,

thanks so much for this guide, it was really easy to follow

i have a question: all i want to do is uninstall bloatware from my xperia arc - will unlocking the bootloader be able to do that? do i have to root the phone as well? do i have to use something like titanium backup to uninstall bloatware, or do i just normally uninstall it?
[Xperia Arc General] shantusingh:
if u unlock bootloader, the official track id, facebook music like n maybe few more apps won't work(then you would need to find them from market to run them and for some files like fbmusic.apk you would need to cut/paste its sys file to sd then restart n install it to sd to make it run)

To uninstall bloatware, i believe you are asking to remove junk files from your sys/app ... u can do that by just having root then move safely the junk files which won't brick your phone to a new folder named "junk sys/app files" (using root explorer would be good) to sd card as back up files then restart your phone. Many files will be removed for sure automatically and will boost phone's performance, if you still see few sys apps in menu then use root uninstaller and remove system apps from it that you dont need and which won't brick your phone (you can ofcourse have those files back if you do a backup as i mentioned above or re flash your phone with a new update,etc later on)

unlocking bootloader is important only if you also want to use custom roms, if you want to just remove some system apps then its not recommended as you will lost your drm files with it. If unlocked then you might need to always flash new updates or any previous ftf using flash tools and other 3rd party softwares but mayb not via Sony PC Companion, sus, etc ....

So good luck, hope this helped or let me know if you want to know anything else :)

First of all thanks to lollylost100 for it's tutorial, the instructions are very clear but i can't to it to my phone... :mad: Been reading this tread and i can't get to any conclusions...

I have a locked phone to a carrier, i'm on windows 7 64bits and my phone has the latest version of Gingerbread.

I turn off the phone, plug the cable with the settings button pressed and the led just goes to orange as it is charging. I don't get any blue led light :(

I've also read on this thread that i have to unbrand my phone... what is that and how do i do it?
