[GUIDE] Boot into fastboot - find out if bootloader is locked

Meister_Li · Apr 5, 2011

Heya, I figured I'd show you how to find out if the boot loader is locked. After some toying around and reading around in the Xperia Arc forums, I figured it out myself.

To try this, make sure you have fastboot installed. It's part of the Android SDK so if you don't have it, install it. Alternatively, it's also included in the application PDANet

Hold the search-key on your xperia play and connect the USB cable. The LED should switch on in blue. If you computer complaints that it can't find drivers for the device install the "Android Bootloader Interface" Driver that you can also download with the Android SDK.

Now type in "fastboot devices". If you can see a Hexanumeric code there, like in my screenshot, the boot loader is unlockable.

fastboot oem unlock sadly doesn't work. That would've been the day.

Still, it seems it expects a code and no code is "0xFFFFFFFFFFFFFFFF" Maybe someone clever can find out how to calculate an unlock code from the Imei?

Anyway, have fun with that for now.

I get the same

That is to be expected. We'll have to wait for Sony Ericsson to help us unlock the Boot Loader eventually.

They announced that they'll only do this for non-simlocked devices.

I don't know how exactly it'll cost them money tho, if some people use a custom OS on their phone?

It will cost them money because when they abandon the phone the developed community will keep it alive. Meaning no one will buy the next phone.

^^^ Kind of exaggerated.

Where did it say only for non-simlocked? Where can I buy a non-simlocked xperia play?

Meister_Li · Apr 10, 2011

I bought mine at gum Mobile and they said it's only for sim-unlocked phones on their blog entry.

TDMaster · Apr 10, 2011

with Bootloader unlock comes Custom Roms that will eventually create Jailbreak for the phone.. of crouse sony will lose money (or really in this case they will make more money cause more ppl will buy the phone) as the PS3

Meister_Li · Apr 10, 2011

All right. How will that make sony loose money? What can you do with a rooted phone that you can't do with a normal one that'll cost them money?

doesnt work

Hey

i have tried this many times now, i turn off my phone, wait for 2 minutes (just to make sure) hold down the search key on my Xperia Play and plug in my USB

i have held the key for up to 5 minutes for all keys and none work

when i press the back key, my computer bleeps as if to say it is recognized

the search key, like you say, does nothing but charge my phone

can someone help me please?

Meister_Li · Apr 10, 2011

Try the other cable that was included with the phone. I think one of them is only able to charge the phone.

Perhaps start a thread with observations made on country/carrier fastboot accepted/not accepted?
Mine is Danish, carrier TDC, fastboot not accepted! (Locked bootloader)

That's a good idea, but it'd probably be best suited for the general discussion forums, to keep the dev forums free.

Started new thread in general
