Question about bootloader - Sony Xperia ZL

I have a rooted ZL. The bootloader is showing as unlockable: No
Why, when sony even provides instructions on unlocking bootloaders, are some phones not unlockable?
Educate me!

It's not Sony, it's blocked by carrier network. It cannot be unlocked through any software, as its linked to chipset

So the carrier locks at two levels? I unlocked the carrier with a code but you are saying that the bootloader is locked by them as well?
Phone was locked to bell Canada. I unlocked it and run on Rogers now.

You can unlock network but not boot loader. Because it's hard coded. Reason behind this is that is something happens to the phone it would be difficult to replace it. There are people who would unlock boo loader at some price. I'm not sure.

[Q] How to unlock network on Xperia Arc

Hi guys,
I have Xperia Arc which was locked to 3 UK. I flashed generic firmware from http://forum.xda-developers.com/showthread.php?t=1115542 , rooted it and updated to 2.3.3 The phone is rooted and unbranded now, but it is still locked to the network. If I put another sim card it asks for Sim network unlock PIN. How can I unlock it?
Thanks
Im on 3 and UK there is no way to unlock it except from a code mate. I pm'ed u

There must be a way around this, it is software issue, I thought the lock was in firmware, but if not, where can it be? is it in bootloader? Or I flashed wrong firmware?

Now I'm really intrigued, why is it not possible? Can anyone explain this?
If XDA wizards have access to firmware source, why they can't remove this lock from there?
Or I know for sure that unlocked smartphones exist, why not to take firmware from them?
This is not a hardware feature (or is it?), so it should be possible to overcome this, am I wrong?
SIM/network locking has nothing to do with firmware/software, hence you can flash any firmware onto any phone and maintain your (un)lock.
It's a lower-level software lock on the radio which is loaded before any firmware.
Think BIOS password on a PC. It locks the PC regardless of what operating system you have on it and is loaded before any OS.
Carrier-branded phones also cannot be bootloader unlocked at the moment, but there aren't any custom ROMs yet so it's not a big issue.
@BluechipJ
Thanks for reply,
Do you mean this is done in the bootloader? I know it is possible to unlock bootloader.
And what do you mean by carrier-branded phones? this phone doesn't have any logos on it. There was carrier splashscreen and a couple of apps but they are gone now after I flashed generic firmware. Is my phone still branded or not?
It is not branded but sim-locked now.

No, the radio/network/SIM lock is separate and independent from the bootloader and any firmware.
Carrier-branded means the phone had carrier apps/logo/is sold directly by the carrier. My Rogers arc does not have any physical logos either. It had Rogers applications and splash but like yours, are now gone since I flashed a generic firmware. However, it is still a carrier-branded phone. It was sold directly by a carrier. The bootloader is therefore, locked and cannot be unlocked (yet).
You can go to the Sony Ericsson site (http://unlockbootloader.sonyericsson.com/) and get your unlock key, but there is no way to get into Fastboot mode to enter it (on carrier-issued phones).
Thanks for the explanation.

I just thought the other brand(s) of android phones is not as secure as this, that we need to pay for an unlock code. Others can just be sim-unlocked by software!
You can unlock the Phone using the Unlock code,You can get the Unlock code from the site www.theunlockspot.com and unlock it..Then you can use in any Country GSM Carriers.
No! It is possible to unlock the phone with proper simlock.ta cuz I have locked it by flashing it. God damn it!
So it is possible to vice versa.

You can unlock your bootloader, but you have to pay
thankx for reply
2 questions
how much?
how to?
There is no need to pay. Simply use this guide to unlock your bootloader for free.
I have an R800i and did it myself. Just make certain that you install Gordon's Gate drivers on your PC otherwise you'll be left with a phone you can not reflash afterwards.
what using Omnius for SE v0.23 ?

That only works for phones which are not sim locked (subsidized) by a carrier. For all those that do have sim locked phones, such as myself, you do indeed need to pay to get it unlocked by someone that has the tools to do so remotely. You can find someone in the General forum that can do it for you.

I was under the impression the R800i always came sim unlocked. Mine did. My mistake. Thank you for the information.

My phone was sim locked to UK orange, too. I paid alejandrisimo just under 20 quid and he enabled fastboot, unlocked the bootloader and removed sim lock in about 5 mins. All remotely. Thread was in the general section.

[Q] Rogers Sim-Locked

I'm kinda new to Xperia Play, I'm a proud owner of a Xperia Arc.
Nevertheless, the Play in question is Rogers sim-locked, I'm from Brazil, and I want to use a "Vivo" sim on the phone.
My question is: If I simply flash a default firmware via flashtool on my Play, I'll be able to use another carrier sim or i'll need to pay for the unlock code in a third-party site.
Thanks in advance.
You'll need the unlock code, flashing firmware wont help you. However you could also opt to get your bootloader unlocked instead which will also sim unlock for you. The difference is a sim unlock will cost about $12ish whereas bootloader is closer to $24ish. However with an unlocked bootloader you can run unsigned kernels allowing you to overclock, undervolt, easily root, install custom ROMs and more. If that all means nothing to you just do the sim unlock, just giving you the options.

I think if you have Alejandrissimo unlock your bootloader, it also unlocks the sim.

sim free but locked BL

hi
just got an Xperia S noticed that its sim free but the bootloader unlock statue is not allowed on the service menu, any thoughts guys?
Bootloader and SIM unlock are two entirely different things. SIM unlock just allows the use of different carriers while bootloader unlock allows for changing system files otherwise locked from being accessed or changed and stops the use of fast boot.

I bought it used, I thought as long as it is sim free, it was bought contract free so it should be factory bootloader unlocked. How to enter fastboot mode anyway ?
If bootloader unlocked allowed = no it means you cant unlock it

If it was baught from a mobile carrier , most likely , it had been simlocked and the user either sim-unlocked by himself or from carrier... then it could be bootloader not unlockable... check by entering *#*#7378423#*#*.
im having the same issue... i will call the carrier to see if i can send to hell the warranty a little bit..

[Q] Unlocked boot-loader still sim locked

I unlocked my bootloader a while ago and have been running PecanCM's version of CyanogenMod 11, i just tried a different sim but its still carrier locked. Does this mean i still have to purchase an unlock code?
Bootloader unlocking doesn't sim-unlock your phone.
