XPERIA Z - bootloader unlock allowed: no, but fastboot working. - Xperia Z Q&A, Help & Troubleshooting

I'm buying Xperia Z (SFR C6603) sim unlock or sim free i don't know.
Working with all sim cards.
I have problem: phone say bootloader unlock allowed: no,but fastboot & flashmode working.
Can i unlock bootloader or not? thanks. sorry for my bad english.

No you can't if it says no.
Fastboot works on all Sony phones, and on not unlockable roms it can be used to flash a pure stock kernel if you want. But you can also do that via recovery with the right update script or with ftf.

[Q] Did it work for you - X8 sim unlock?

Ok, I saw many people asking how to unlock our X8 on all networks and I tried it on four Xperia X8 phone's and it's true, bootloader unlock succesfully unlocked X8 on all SIM cards. Yes, it asks for SIM Unlock code but I've just pressed dismiss button and it connected succesfully on other networks. I've unlocked bootloader with Flashtool v 0.5.3 and it worked on all (2.1, 2.2 &2.3) ROM's. Please try it and answer if you've succesfully unlocked your phone.

I try to put VIP SIM card but it just won't connect to network. when I manually select VIP I get some massage. don't remember what exactly, but about forbidden network or something like that.
So I guess you are just lucky, cause it doesn't work for me.
or perhaps somebody else could write if this works for him. which networks, which flashtool, how did you unlock ...

The only time i have ever seen this is on phones that already have sim unlock. When you turn on your phone on a sim free phone which already had been unlocked it asks (EVERY TIME) to enter your network unlock code even do its already unlocked to all networks. The flash tool doesn't unlock your network

If you UNLOCK BOOTLOADER with FLASHTOOL, your mobile network will work on all operators! But if you unlock bootloader with msm7227 you'll not have signal!!

I l 'I unlocked the flashtool but I signal with a single operator ... why?
Oh,
I just realized what you wanted to say.
Bootloader can be unlocked with flashtool and, if done so, SIM unlocks too.
That's a huge thing, and should be made sticky, if so.
and what about us that unlocked bootloader before?
do we have to reflash stock kernel and relock bootloader? or can we just try to unlock with flashtool already unlocked bootloader?
I don't need my SIM unlocked now, but it would be nice to know. So, if somebody tries it please post how you did it.
I unlocked my bootloader (With msm7227), but its not sim unlocked. I have a custom kernel and custom rom, but still can't use my phone.
Any ideas?
sorry If I open this thread lot of months later, How can i unlock bootloader of this x8 with flashtool? these are the features of flashtool
Flash original Images (Android 1.6, 2.1, 2.3 Images)
Root your phone
Install Recovery, Busybox, custom kernels
Clean your Rom (remove /system/apps apps of your choice) (Be careful, unless you really know what you do, do not modify the default list. This can make your phone stuck at the SE Logo)
Clear dalvik cache
Optimize (install of JIT v2) (Disabled in 0.4, will readd it as a plugin for 2.1 phones only)
Customize (installs apps found in the custom/apps folder of the flashtool)
Clean uninstalled (remove any references to system apps removed in the Clean (root needed) step)
Edit any text file on the device
Rebrand your device
Click to expand...

Which one is for me? Thank you!
1. connect phone to pc
2. enable debugging
3. you must have latest flashtool
4.launch flashtool
5. go to "Plugins" at top and click unlock bootloader.
Good luck!
Or you can go on yt and search for 2011matej in channels and find my profile. There is my video how to unlock bootloader with flashtool:good:
i unlocked the bootloader by msm 7227 and it isnt sim unlocked.........the phone is e15a but it cannot be used in other networks......is there a way we can unlock a e15a that is rooted and bootloader unlocked by msm7227......help would be appreciated.....and i searched but didnt find any solution
I have unlocked with msm7227 and i just tried and it isn't sim unlocked. I already have an unlocked bootloader but Can I just go into flashtool and unlock it there?

If you have unlocked bootloader just do it next step:
If you want to flash it with Flashtool, you don't need to lock your bootloader.
If you ask for update with Pc Companion or Update Service, furst lock your bootloader and then try.

You cannot unlock the Bootloader if it says "Unlock Bootloader Allowed: No" in your service menu.
And trying any other methods to unlock it will probably brick your device. There are a lot of LB ROMs out there try out. Try them if you want.
Of course i want to change the rom, but for example cm12 has a lot of bugs and the other roms are for UBL. .
