Hello
I currently own an Xperia Live with walkman which I upgraded to 4.0.4 ICS and rooted.
I'm interested on using custom ROMs so I need to unlock the phone's bootloader in order to install custom kernels.
In the service menu of the phone, rooting status says:
Bootloader unlock allowed: NO
I've read on other threads that this means that the phone also has a network lock, so even if I use the test point method to unlock, I won't be able to use fastboot mode.
However on the SIMLOCK menu of the service menu, all locks are disabled (And I confirmed it by installing another sim from a different phone company).
¿How can I unlock the bootloader (for free, hopefully), and will it work on fastboot mode?
I would advise you to try and go to fastmode connecting the phone to the computer while off and holding the volume up key, the notification led should turn on blue that means that you will have no problem flashing custom kernels but you will need to unlock the bootloader using the test point method.
Also you can double check if the boot loader is really locked in the service menu, software info, under the s1 Boot Version you will find something like this: 1241-3656 r9A029 the letter "r" here refers to the state of the bootloader the lower case means it's unlock meanwhile the capital "R" means its locked.

He can't use fastboot, because Bootloader Unlock Allowed: No.

So, I will never be able to use fastboot?
Even if I unlock the bootloader through test points or the paid method?
Normally, you'd have to unlock it via Wotan Server. It erases SIM lock and unlocks bootloader. Don't know why your phone is already SIM unlocked, though.
Hi,
I have same problem, Bootloader unlock allowed: NO
On every test point tutorial I saw "if Bootloader unlock allowed: YES, than you can continue doing TP".
I want to unlock it, so I can flash CM9.
Can I still use TP to unlock my bootloader?
No, bootloader cannot be unlocked if fastboot is disabled.
The only way to enable fastboot right now is via paid method, which also uses the test point method. I am not sure, but I have heard that in some cases, that method unlocks the bootloader aswell.
So, no custom ROMs for me
So what's the verdict here?
Even though on my LWW I have Bootloader unlock allowed: NO I did the testpoint method to unlock the bootloader and it passed. Afterwards I have S1 Boot Version: r9A021 (notice the r) which means the bootloader is unlocked AFAIK. However I still have no access to fastboot. I can confirm that the phone is simlocked, and before having to pay to get it simunlocked, I want to make sure that doing so will finally enable fastboot.
Again, will having the phone sim-unlocked enable the bootloader to be unlocked, and more importantly gain access to fastboot?

Yes, the bootloader is unlocked, but fastboot is still disabled and phone SIM-locked. The only way to enable fastboot is via paid method.

That's exactly what I am asking. If the phone gets sim-unlocked, does that mean that fastboot will be enabled? What paid method are you referring to? Sim-unlock code? Or is there some other paid method?
Or to put it in better writing, what paid method is there to enable fastboot?

The paid-method is technically you go to your service provider,and ask them for an unlock code for your phone.Normally,you need to pay,but if you are lucky,they can give an unlock code for free :good:
The method to sim-unlock your phone (based on my reading in this forum ) is insert other SIM card that are different carrier,and turn on your phone.There will be a checkpoint which your phone asking for a code,at that time you insert the code that your service provider gave you,and after you enter the code,your phone will automatically sim-unlocked :highfive:
I'm sorry if some of my information is misleading,I hope someone can fix my mistake (if any though)
Or try this,who knows it might work?

I'm planing to buy an unlock code, just want to make sure that by simunlocking it will enable fastboot.
Only wanted to know if anyone knows that it is certain, because i have no need for simunlock other than enabling fastboot so I can flash kernels

I unlocked the sk17i of my son with another simcard and the code from my provider but... bootloader is still NOT allowed
Have you tried the testpoint method to unlock the bootloader?
Unlocking bootloader and sim unlocking both do separate things, but I'm hoping simunlocking + testpoint method will finally enable fastboot.
I'll purchase a simunlock code and post if that helps with enabling fastboot asap.

That's is called sim unlock,and it is used to unlock the phone to use other sim card provider...it also unlock fastboot in your son's phone
Well,the bootloader still can be unlock,see my previous post

You need to flash the phone in EDL mode. Take it to a service center or find online service which can do it remotely.
use this
fastboot oem edl

You have to get the sim unlocked. Once that's unlocked, the option to unlock the bootloader is available.
There is already a thread on this subject.
