Defy sim-locked & custom ROM

Hi to all...
I'll buy a Motorola defy Vodaf* Spain locked, but i would like to use a custom ROM and another phone operator, so i need to buy an unlocked code or just to put the new Custom ROM?
Otherwise if i unlock by code and then i change my sim, i need to unlock again or the operation is permanent?

You cannot unlock your phone only by installing another ROM. Have a look on this topic for more details on how you can unlock it.

Is it possible to unlock bootloader if phone says it cant be?

I went to see if my bootloader can be unlocked from the sony website.
I followed the instructions by putting that code into my phone dailer.
Under the section if it says my bootloader can be unlocked, it says no.
Does this mean I CANT use custom roms?
Is there no other way to unlock the bootloader?

You can always unlock the bootloader, it's just a matter if it's free or not. It all goes back to whether you can use fastboot or not ( the tool used to flash kernels). If you bought your phone sim unlocked it more than likely means fastboot is enabled and you can unlock for free through sonys tool and be on your way to flashing custom kernels. If your phone is sim locked or you paid to get the sim unlocked by a code then fastboot will be disabled. So to rephrase: turn your phone off, hold the search button and plug it in to your computer, if the status light goes blue (and you're not on a CDMA one, r800x) then fastboot is enabled and you can unlock for free through sonys utility, otherwise you're going to have to use a pay service like this (~$24):

And to answer your question, yes and no, while it's not possible to flash ROMs that use a custom kernel like cyanogenmod without an unlocked bootloader you CAN flash stock based ROMs through the recovery made for locked bootloaders.

I have an R800A from Rogers.
The LED doesn't go on at all when I press the search button.
When I goto sony's website, I go into the phone settings, where it says if the bootloader can be unlocked, it says NO.
You mentioned a paid servers. Is unlocking the phone by allowing it on another network the same as unlocking the boot loader?

No, that's sim unlocking. Confusingly a bootloader unlock will actually sim unlock you as well though, the difference between the two is a sim unlock is a code and the bootloader unlock is done through test points. So ya, if you didn't get the blue light your only option for unlocking is a paid service, sorry.

Well actually an unlocked bootloader allows booting of custom(unsigned) kernel images and can be achieved with various means according to the situation.

Which is what I said in my above post... And the only ways to unlock it are:
- Through sony's online tool if fastboot is enabled and you have an IMEI (sorry CDMAs)
- Or a test point unlock, such as setool2 or omnius, which will enable fastboot

Oh ok sry then, thought u were being general.

Thanks for the help. I contacted the guy about getting it unlocked.

[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.

Yes unlocking the bootloader will unlock sim lock too, 2 birds with one stone!

[Q] Carrier Unlock Question

Hello. recently I read on a section of the HTC One X forum that if you want to unlock the carrier of a HOX and you have a custom ROM flashed and bootloader unlocked you need to lock back the bootloader and flash a stock ROM. Is it true, or can unlock it with the custom rom flashed?

You can`t disable the carrier lock without s-off.

Thanks for the answer. So there is no way someone could unlock the carrier if i have S-on?

No, sorry....
There is no way without S-OFF.:angel:

You can unlock your carrier to allow different network Sims, just google "HTC one x carrier unlock".
It's not possible to change your cid without s-off

Here comes the problem.. I know that cellunlocker.net is trusted when comes to unlock codes and i got my code yesterday. I was on Custom ROm with bootloader unlocked. When i enter the code it says it's incorect so that's why i need to know if i need to relock the bootloader and go on stock rom?

I had the same situation.HTC locked device with the code you can find on websites but then your carrier changed unlock codes,and the one you bought from site is incorrect.
I asked my carrier to tell\sell me the code but they dont want to untill the warranty is over.You can ask your carrier also,it doesnt cost you anything
My local phone repair service tell me that only solution for me is to take apart phone and read codes directly from motherboard but then i will lose warranty,which is ok for me,i already unlocked bootloader and root my hox

Just relocked and flashed stock rom. I will contact the carrier and try to get the code. Thanks for the help.

Am I Unlocked?

I've got CM 11 ROM installed. By virtue of the custom ROM is my phone unlocked or do I need to unlock it? If I still need to do something to unlock it, what is the easiest/cheapest route?
Thanks in advance!

Duh. No I'm not unlocked (Google Search) and I found this thread. http://forum.xda-developers.com/showthread.php?t=1962453
Just posting this for other newbies to unlocking.

Rooting + custom roms doesn't mean your phone is unlocked
and I do not know if you're actually unlocked unless you tell me, the obvious way is to try other network sim. ie. Tmobile
or *#7465625# if you're on Stock.
also there're 2 ways to unlock: Free or Paid
Free: IF and ONLY IF your bootloader is not 4.3 Bootloader, ie. MK5 or MJB
Paid: buy an unlock code and unlock (prices are varies)

If you have the 4.3 bootloader and you buy an unlock code, you should revert to a stock ROM, enter the code, and re-load your custom ROM.
