Hello everyone, I'm Santiago, from Argentina. I bought an Xperia Mt11i (Neo V) smartphone last year from argentinian phone carrier Claro (ex-CTI).

It's my first android phone and as I came to learn a bit about the system, I wanted to unlock my bootloader o I could install custom roms and kernels, as I have been playing with some cutom roms, but I can only access the ones that do not require Bootloader unlocked (i.e., I can't install CyanogenMod, MIUI v5, etc).

Checking in the SERVICE hidden menu, the status in my phone says "Bootloader Unlock Allowed=NO" (so I coudn't follow the official Sony guide to unlocking the bootloader) and I contacted my phone carrier to ask them wether they could do something about it, either by free or paying methods. They replied that bootloader is a device function, not a service provided/modified by them and that I should ask directly to Sony. As there is no Sony mobile branch in Argentina, I went to the talk.sonymobile forums to post my question in hope that someone may be able to tell me wether something can be done about this. Over there someone said that they thought it could be done (something about having done it with xperia Z), that I should ask over the xda forums, so here I am.

I searched info over the forums but didn't find any threads regarding my specific problem, which is changing the "bootloader allowed" status from NO to YES with phones bought from a telephone carrier. I've found tons and tons of info on how to unlock the bootloader, but all of them are for "bootloader allowed=yes" cases, so I thought it was worth the shot asking about this.

I should also add that my phone is in fact SIM-locked at the moment, and I have no idea wether this is a limitation for what I'm trying to do or not. Reading throughout the web I encountered several places that said that SIM-Unlocking your phone via NCK code (which I could obtain from my phone carrier) does not, indeed, unlock your bootloader, but I was wondering if it might, at least, change the status to "Unlock Allowed=YES" (this, I read, is sometimes the case).

I am eager to find a solution to this situation, so any help will be much appreciated.


Thanks in advance!

Santiago.

Well that's too bad, I was really hoping I would be able to somehow.
After calling Customer Service a lot, I'm now waiting for a direct reply from my phone carrier about the subject. Over at the sony forums they told me that Sony couldn't unlock it because of legal issues with the phone carrier, as the phone carrier is usually the one that demands to have a locked bootloader. I'm still hoping, however, that there'll be some sort of workaround and that either Sony or my phone carrier will give me some sort of solution. It's been done before, apparently, with Movistar in Spain. Apparently Sony was able to unlock the bootloader for those that bought an Xperia 2011 phone with Movistar Spain that had "Bootloader Unlock Allowed : NO". I can't post a link that thread yet, as I'm still new here at xda, but I'm quoting what it says over there: "In a nutshell "The Solution Sony proposses is, for those of you with a code-unlocked terminal, to contact Sony at questions.es@support.sonymobile.com, with your email, imei and unlocking code".

I know it's a particular case with Movistar Spain, but I'm still trying to get some info on wether something similar can be accomplished between my phone carrier and Sony.

Thanks for your reply, and I'm still hoping someone over here can tell me something about all of this.

It's your phone carrier mate, they locked up the phone. Call them everyday until they remove the sim-lock on your phone..

For me Linus Torvalds is the greatest man on earth

Well that seems to be the case, even though they are playing dumb and saying they are not the reason for locking the bootloader and that I should contact Sony and have them solve the problem for me....
I think I'm about to go into war with these guys. I kinda get why they lock the bootloader, what I won't forgive is being lied to like this. It's outrageous.
I'll check this post periodically though, maybe there's one of those miraculous solutions that I can try in the meantime.
Thanks for replying anyways.

Sadly even if your bootloader is unlocked you won't get to install the custom kernels
As your fastboot would still be SIM locked
And that can't be undone by Sony ofcourse
--You've to unlock fastboot
--Unlocking bootloader is no big deal -you'll have to pay few bucks and use wotanserver or s2 tool

There's a guide on using Testpoint (unofficial) unlocking in Neo V development section
Hope this clears out your issues more clearly
