Bootloader question - XPERIA X10 Q&A, Help & Troubleshooting

I am kinda confused about the bootloader. So do you need to have an unlocked phone to unlock the bootloader? Because I'm a little afraid to do it because of the loss of radio signal! Please help
and i checked on that tool thats supposed to check if you can unlock the bootloader and and it said ready. My phone is not unlocked from the carrier.

If your phone isn't unlocked then you can use the SEMC_qd8250.zip to method to unlock your boot loader, but you can always use the SIM certificate check tool in the dev thread to check if what SIM certificate your phone has, post the tool in a second.

Yes i know you told me earlier in a pm,
but does anyone now how you unlock network with setool?
x10 stand not in the list, only very old phones.
actually no. you dont have to unlock your phone carrier. i unlocked my bootloader without unlocking the phone carrier. there is a tool to check if you are eligible for unlocking your bootloader
You do NOT need to use setool to unlock your carrier before unlocking bootloader!
I was sim locked to vodafone (And never used setool) and I have unlocked my bootloader by following the steps posted in this thread with the kernel upgrade/downgrade method.
If you have never unlocked the sim then you can use the tool posted the_laser to unlock the bootloader.
Ok thanks mates

i have looked round for the answer myself, there seems to be alot of threads on this, all of them say no you can not unlock it unless using a payed method such as wotanserver also you most probably will need to sim unlock first, i think that then changes the status, well thats what i have read has happened to some, and a little something else the fw is the number such as 2.3.4 or 4.0.4, and the build number is the 4.1.b.431.
If you unlock it for any network using wotanserver it will unlock the bootloader aswell, I used them and it was fairly easy.

Can I unlock?

Hey everyone
I need a quick phone to last me a few months till my upgrade and the Neo V seems like a good deal, brand new for £70.
Now I never buy an android phone unless the bootloader can be unlocked. I understand that phones made after 12w14 cannot be unlocked or something? If the phone is made after 12w14 is there really no way to unlock it? It will be sim locked and I know it's necessary to unlock it to allow fastboot.
Basically can phones made after 12w14 be sim and bootloader unlocked?
Thanks

If you buy your phone brand new from an 'open' store than your phone should be sim unlocked.

If you want to know whether you can unlock your phone or not, here is an excerpt from Sony's forum.
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.

Thanks but the phone will almost certainly be locked to T-Mobile.
What I need to know is, if the manufacturing date is past 12w14 is there a way for me to sim unlock and then unlock the boot loader ?

If I'm not mistaken, there is but you've to pay for it as your status says :No
You may use SeTool2
Or Wotanclient for doing so

Bootloader

I have a x10 running 2.3.3 official firmware.
I have rooted it.
So have I unlocked the bootloader?
If no,how to unlock it??
Sent from my X10i using xda premium
Rooting is not part of unlocking bootloader. Check first by dialing *#*#7378523#*#* and if bootloader says YES then you can unlock it. But if you are locked in a specific carrier then you need to unlock your sim first then proceed to unlocking bootloader. Check the development thread and look for proper bypass for bootloader unlocking.

[Q] Ways around Bootloader Allowed: No

Hey all,
So I've been searching through these forums trying to get my head around the problem of Bootloader Unlock Allowed: No on my L22i, but there's so many threads, and I'm seriously struggling to figure out my best plan of action, so please do forgive my ignorance!
I've checked and my phone is Bootloader Unlock Allowed: No. It seems that there's a lot of ideas tossed about, but no real solution given. All I'm trying to do is go from 4.0.4 to 4.1. It seems that it is possible to flash roms without bootloader being unlocked, but obviously I'd just prefer if bootloader was unlocked. I had CM on an old HTC of mine, and I'd even like the option of migrating to that in the future.
So what are my options? CWM Recovery to root my phone to unlock bootloader? Flash a rom that has bootloader unlocked? Something else?
Like I said, I've spent the last while looking though the site to see if I can get my head around what I can/cannot do, but it's all very confusing, so any help would be appreciated. (Beyond just telling me to search.)
Cheers.
Flashing rom will not change the status. Flashing custom kernel not recommended, it will brick it. Bootloader unlock is done via sony web page, you'll get a code which you'll insert into phone and thats it.

http://unlockbootloader.sonymobile.com/
Just read and maybe contact sony directly
And read this
http://talk.sonymobile.com/thread/127808
This will give you thr direction.
On short, this option is ussually operator request. If you obtain unlock code from operator toget the phone sim free then you might go to sony centre and ask staff for bootloader unlock.

After you gain unlock code from your operator, so your phone will be sim free, then you might go to sony centre and ask them to unlock your bootloader. Its operator whos asking this stuff to be done, but once your contract over, or you'll get the unlock code to make it sim free, then you can ask sony to unlock bootloader.

unlock code
how much time do we have to wait to ask for the code from the operator?
here in Portugal i think that is 2 years in any operator, but i'm not sure
Tiil end of your contract or you can asl what you need to do whrn you want umlock.
Sent from my MT27i using xda app-developers app
but i don't have contract, i've been with this nunber almost for 15 years, but i bought my xperia u almost 2 years ago.
i better get info with the operator :good:
If i got an unlock code, not from the mobile phone company, but have it and the phone is sim unlocked already, if i send them that code they can still unlock the bootloader?
I have a Xperia U with bootloader allowed: no and SIM lock. Is there any solution to unlock the bootloader?
Ask them...

Guys, i want to make it clear on this thread.
If bootloader unlock allowed: no is there, NO ONE CAN HELP YOU. NOT EVEN SONY. ITS YOUR FREAKING TELCO THAT CAUSED IT. FIND THEM, NOT XDA.
