Non-Unlockable bootloader + Fastboot? - Xperia Arc Q&A, Help & Troubleshooting

Hey guys,
I know that some phones bootloader cant be unlocked. I checked mine and of course mine couldnt be unlocked.
My phone is locked to Vodafone and for the love of god I would like to use CM10 on my Xperia Arc S.
Two questions.
1. Is there no possible way to unlock my bootloader?
I mean Sony does officially support unlocked bootloaders. I requested a unlock key and they sent it to me. (I read about having to call your carrier and getting a code of them which can cost up to 50€ or so?)
2. (This is just to make sure that im not failing at a simple task) You can´t Fastboot with "non-unlockable" bootloader correct?
If anyone knows how to install CM10 on a locked bootloader or how to unlock the bootloader with out having to a pay a ridiculous 50€ I would really appreciate it.
I mean I simply can not understand why I should not be allowed/able to unlock my bootloader on MY phone. Its like as if I buy a house and im not allowed to unlock the front door...
Thanks!

Yes, click the first link in my sig, which is a sticky in the general section which I wish People would visit instead of coming to Q&A to ask for answer that can be found in the stickys.

Thanks for the reply but I have read that post and I am a little unclear on something.
Primarily this:
There are three ways to Unlock yours, the Standard/Official method (For SimFree/Un-Branded Phones) which is explained HERE, (PLEASE NOTE! - You loose DRM when using the official method but not with the TestPoint) but if your Phone came from a Carrier then chances are (99%) you won't be able to use that method. There is a simple method of checking if you can or not which you'll find HERE.

Do you mean that the 2 ways under that quote are for people with locked sims or do you mean its generally not possible?
Sorry for the stupid question but id rather be safe than sorry.

Unlocking bootloader has nothing to do with locked SIMs.

You need to use the third method as the first two are for SIM-Free, unbranded Phones.

Hmm seems like the only way it could be unlocked is if I pay for it.
Thats lame.
Thanks anyway.

[Q] Debrand and rooting.

Hi, about to pick up an Arc S, can it be debranded? Can it be rooted? Is everything reversible?

Thanks but none of those links really answer the questions.
Put another way, if I want to unlock the bootloader, can this only be done on unbranded handesets, or does it work on network provided handsets too?
What questions should I be asking the seller, to ensure I get a handset that I can unlock the bootloader and load a rooted ROM if I wish.
I don't want to buy a phone that I can't root.....

I have read them all, and really none the wiser. Does it really matter if I buy a unlocked network Arc S, rather than a true SIM-FREE one? Is there anything I won't be able to do with the former that I can do with the latter?

Any can be unlocked, but network locked requires SETool, SimFree just needs S.E's method. My phone came network locked from O2 but is now Debranded, Boot and Sim Unlocked. The Debranding I did myself and Alejandrissimo Unlocked my BL and Sim.

Thanks. So is it worth the hassle, I can get a SIMFREE from Play.com for £339 or a network unlocked S for £50 less. (I can get some cashback from play.com, making it closer to £30 difference).
Is it worth paying £30 more to get a true SIMFREE phone, and avoid the risk of bricking it, and i'm guessing benefiting from quicker updates.

[Q] Network Unlocking

So I've heard about bootloader unlocking which, I guess, enables me to have full control over the device (not like rooting, I understand that) and to do stuff like flashing new ROMs, etc.
But what about network unlocking? I mean, I'd like to be able to use my phone on any network I wish, do I need to unlock the bootloader for that? Do the network restrictions automatically disappear if I unlock the bootloader?
Also, is there anyway I can disable network restrictions by myself (without using something like a special SIM card or asking for remote unlocking) without having to pay for any unlocking service or ask someone to do it for me?
Thanks in advance! :3

Hi, so to answer your question, when you unlock the bootloader the sim lock remains, also afaik there are no "free" ways in which to remove the sim lock at this moment in time, the only way is to get the unlock code from your service provider or pay a remote unlocking service.
I think i may have seen on the arc forum somewhere for a small fee you can get your boot loader unlocked and sim unlocked at the same time.
One last note if your arc is sim locked there is a chance that you wont be able to unlock the bootloader via sony ericsson developer world, depending on your carrier

That means it's also possible to unlock the boot loader remotely?
Also, if there's someone who can do it for us (small fees inc.), that means there's actually a way to do it, right?

Yes there is a way to do it, i cant remember how much it costs exactly, but it's done remotely and sim unlocks and boot loader unlocks at the same time
And is it something I can do by myself?

If someone else can do this as a paid service. Why can't someone explain how its done and make it available for free?

As for that i cannot answer.. But at a guess a lot of hard work will have gone into this. It keeps drm intact, provides Sim unlock and enables fast boot on handsets which didn't have it before, if i was in that situation with my arc i would have gladly paid, and i myself think the Dev/Devs are entitled to some hard earned cash

[Q] can 12W19 be sim unlocked by ANY way?

is there ANY way that xperia arc s newer then 12w19 can be sim unlocked??
Purchasing code or..??
Can cellunlocker unlock it?
Atm no, I think.

If you're not locked to any carrier, I don't see any reason why not.
Have you tried the official Sony unlock method? Your other option is via the testpoint method.

My bad, I didn't wrote sim locked..
It's carrier locked, and sim-lock is there for 24 months, the problem is I bought it in another country and in my country that carrier doesn't exist..
So the question is edited, can it be sim-unlocked (bootloader is irrelevant)
Then you'll need to use the Testpoint method. Contact Jinx13 or Alejandrissimo. They should be able to unlock it for you remotely for a small fee. Or use Omnius (again Paid).
And no, there's no free method to unlock your phone. But trust me, it's worth it.
Hope that helped. Cheers!
I already did contact jinx and he told me that if it's 12w14 or newer he can't unlock it :S
I'm not looking for a free method, I'm looking for a working method...
Off topic: Is it worth upgrading to ICS?
Damn, then you may be out of luck. Do ask around though.
And upgrading to ICS. Well, I have upgraded to the Generic Global World 4.0.4 and I must say I like it. My only issue is that my touchscreen isn't AS responsive as it was on GB.
There are others who couldn't/can't stand ICS and reverted back to GB after a few days with ICS. They felt that it lagged too much compared to GB etc etc.
To each his own. But I like ICS; that's just my opinion.
Cheers!
is there ANY other way?
is there anyone that has Emma and a working account and can remove the sim lock?
Also can these pay sites unlock it?
maybe fastgsm
I was looking for the exact same thing and found that fastgsm.com can unlock it with network codes.
It seems that we cannot currently unlock this phone model with our data cable method if the manufacturing date is later than 12W13, please contact [email protected] and ask for a refund. It would be possible to unlock this phone via Network codes, if there are unlock attempts left, for $59.99.

Good day to everyone and sorry to revive this thread, but i didn't want to ask a question that's been asked before so while searching the forums for cellunlocker.net i found this thread.
Is there anybody out there who got their arc S(new security manufacturing date 12w26) unlocked by purchasing the code via IMEI method for 39,99$?
dont paid

There is no known solution for disabled fastboot cases yet (Bootloader unlock allowed: No), as phones manufactured after 12W11 have enchanced type of security, for which there is no exploit yet.

It might remove the SIM-lock (I am not sure, which code you mean right now), but it will not enable fastboot and will not allow bootloader to be unlocked.

Would you at least bother mentioning your methods for this? Considering you haven't been around on this forum for long, I doubt any of your methods actually unlocks the bootloader.

Hi,
Thanks, i see there: http://www.fastgsm.com/en/sonyerics...-unlock-codes/network-unlock/flashing-debrand
Unlock codes. I read a lot, and i figured out that Bootloader Unlock Allowed: No means that fastboot disabled due to simlock..so if there's no simlock on the phone, the no changes to YES, so can unlock simply..If unlock allowed YES, then everyone successfully unlocked the bootloader in this forums. Am i wrong somewhere?

It does remove the SIM-lock, but fastboot is still disabled. Removing the SIM-lock does not activate fastboot nor does it change Bootloader Unlock Allowed to Yes.

[Q] Bootloader unlocked allowed: No. Simlock removed

I recently got my Sim-Lock removed from my old Xperia Arc S, and hoped this would solve the Bootloader unlocked allowed: No
Sadly. It didn't change anything. Are there any solutions on what I can do to get this to say Yes?
I'm pretty new to this rooting, bootloader things so may be a really dumb question.
Your fastboot is still disabled. What is the manufacturing date of your phone (under the battery, for example 12W11)?
Also, questions should be posted in Q&A section, not General.

You might be able to unlock your phone's bootloader with test point method. Search the forums, there are guides for that.

That requires that he pays for a unlock at Wotanserver, which pretty much resigns the whole bootloader. The regular testpoint method doesnt work on previously simlocked phones.

You will never be able to unlock the bootloader on that phone, unless your carrier can give you some kind of code to change your unlock status (not sure this is even possible).

The BL is different, if it came from O2 then chances are you cant unlock the BL.
So there is no chance? It worked with xperia arc and omnius. Costs about 15$, that would be ok. But will it work with our z1c in the near future? Or is it just "luck" to find an exploit?

Well nothing is impossible, but it isn't likely as it requires a bootloader exploit. Realistically it isn't going to happen though, unless some smart people devote a lot of time to it. The most likely scenario (using test point to gain more software access) would require hardware tampering.
Hello Mentalghost,
Unfortunately there is no way to unlock the bootloader when the status is "No".
Have a great day, cheers!

MentalGhost, where did you purchase your phone? This phone isn't sold by any carriers in the USA, to the best of my knowledge, so the bootloader shouldn't be locked.

Bought in UK where I am not in USA. Might take back to shop where bought from and see if got any others in lol
Or wait for locked bootloader versions or someone makes modded version with unlocked rom that is been modded like one where you install modded that is unlocked install and then can unlock bootloader did in xperia s I use to have was a modded rom that was originally saying bootloader unlock no and added new Base rom and then said bootloadr unlock yes maybe this will happen on this phone in time or locked bootloader kernels and rom come along

Plus, there will be no solution. The reason why Xperia Arc S and other 2011 Xperias worked with testpoint method was because of that there was a big security flaw in the security of the testpoints nand access, but those flaws have been fixed in newer Xperias and newer 2011 Xperias also.

+1 It was coming to that realization that I sold my O2 locked Z after 6 months to buy an unbranded Z1 Compact. It worked out cheaper too spending hundreds of pounds up front for my Phone with the added bonus of having access to all of it.
