Simple sim unlock question.

Hey everyone,
I've been searching on here and somehow I'm not finding ANY helpful info on how to unlock a G1 to work on AT&T. I want to buy one of craigslist and it seems most people aren't able to get customer service to unlock it for me.
Is there any way to unlock it, even if i need to flash the ADP1 firmware or something?
I really thought there would be a sticky for this, but so far all I've found is paid services.
I can borrow a friend's T-Mobile sim if i need one temporarily to access anything for the unlocking.
Thanks!
-Taylor
P.S. I'm hoping to buy one today, so the sooner someone answers my question the sooner i can get in on this new android love!

I believe as of now you have only one choice - buy unlock code on eBay or some other online shops.

get the phone and have a friend that has t-mo say that they are going out of the country and they need the unlock code for their phone. t-mo will ask for the IMEI and you give them that and they will email you an unlock code. but i am pretty sure that you will be stuck with edge network on at&t. not that i have any choice as t-mo STILL doesn't have 3G in stl

Hey, thanks for the help. I only have one friend with Tmobile and she probably could have helped me, but i was hoping there was a more guaranteed way, in case that didn't work. So flashing the ADP1 firmware and bootloader doesn't do it? I assume that the right people have looked at this and all that?
Well it would be cool if we could crack that, but lucky for me i finally found someone with an unlocked g1 at a great price - $250 for a barely used one with accessories and box, still with the original plastic on the screen, it's basically brand new! I was going to buy one that had been used for a few months, just had a charger, and was locked for the same price! I actually thought it might have been stolen till i met the kid, he was driving a brand new car and only looked to be about 18, so basically he was just rich and didn't care too much if he got the most he could get, heh.
So yeah, I have a G1 now and it's unlocked and works great. I of course don't get 3G on ATT but i had an old iphone before that didn't have 3G, so i'm at least not worse of. And somehow the G1 downloads pages much faster than the 2G iphone, interestingly enough, so I'm pretty happy.
Thanks for your help guys. is there a way we could maybe sticky this or something, maybe make a new post that is the official sim unlock thread and sticky that? I never found a place that specifically said you couldn't unlock it, except for a few posts from before the phone was even out with people speculating, so it was pretty tough for me to find out. Sure, i didn't find anything that said you COULD unlock it easily, but i didn't find a lot the other way either and i wasn't sure if I was just missing something.
Thanks,
-Taylor

I used this one to unlock my g1

within 20 min, I received my unlock codes. And it really worked
as t-mobile asked me 125 Euros for unlocking (the Netherlands)

[Q] Bell Xperia T - unlock

Has anyone been able to successfully unlock the Xperia T locked to Bell?
I have tried with 3 separate online unlock Companies. All three have failed to generate an unlock code. They were all very apologetic and refunded my money but the phone still remains locked...
Any suggestions before I take it in somewhere and have it unlocked via cable and software? This will void the warranty though.
Thanks

Hi,
I have a Rogers Xperia T and also tried two companies that failed, and then found one that succeeded, though it took 4 days to get the code.
http://unlock.canadagsm.ca/ was able to provide the correct code for me. They are more expensive, but if you need help their service is excellent compared to the others I've tried. (I am in no way affiliated with them, to be clear).
PM me if you need more information.
BTW, you can't have this model unlocked with SETool at the moment, if that's what you had in mind by "cable and software".

I saw this on youtube the other day, the person apparently used cellunlocker.net

Maybe give them a shot? According to the video it's about $30?

I used bellunlock.ca. Took three days but worked.
Cheers

Unlock codes
My provider is MTS, their website says to unlock you just have to swap out your sim card and put in one from another provider, enter the code and you are unlocked (for free). Does this permanently unlock the phone? I know that my provider will unlock it for $50.00, I've followed search links and discovered $45 codes are avail - not worried about price - but what about reliability? This will make the process of flashing much more simple for us if it's been proven.
So after little research I found (unfortunately) the definitive answer I was not hoping for. Apparently sim-unlocking your phone is not going to unlock
your bootloader - noobie idea I had - so it does not get me very far down the road of customizations. Too bad, but I have faith in the creativity of the devs out there.
Buying them beer seems like a good idea.

Bootloader unlock allowed: No.

Hi everyone, first post, go easy on me
Anyway, I picked one of these up at the weekend and I'm very happy with it, but I'd like to try the new roms that are starting to appear. Unfortunately, I'm not able to unlock my bootloader (Bootloader unlock allowed: No). This is on Three UK.
Is there ever likely to be a workaround for this?
I'm gutted

I have the same thing on mine (T-mobile Croatia), I reckon it's a network carrier lock.
But if I have faith in something, then it's in XDA, the place where people turn "you can't do that" into "you can, it's just that no one found a way for it YET"
Let us be patient and see what will happen.

mine is the same
Bootloader unlock allowed: No.

Same here on O2 UK. I've just arranged sending the XZ back to O2, with this being one of the major factors that made me decide to wait for the S4. Shame.

I can't root my device

That's why I got my phone from a third party (CPW/P4U/etc) they nearly always supply generic handsets that are unlocked and bloat free.

Yup. Always purchase unlocked devices. NEVER count on a manufacturer's locking mechanisms being broken, nor on the lock mechanism returning somehow. (Qualcomm's secure boot infrastructure is quite strong, so it's rare for it to be compromised unless the OEM handset manufacturer screws up. Since the T's locking was never defeated, I wouldn't hold much hope for the Z.)
Vote with your wallet - don't buy a device unless it's unlocked. If you buy a locked-down device and rely on "unsupported" locking mechanisms, you are implicitly saying that you are OK with locked-down devices.

..

AW: Bootloader unlock allowed: No.
Branded and/or sim locked Sonys are usually not unlockable. This is documented well enough.
As Entropy said, either buy generic devices from the open market which come slim and neat to begin with or go with an operator which doesn't sim lock or brand devices sold by it.
I can recommend mine, sells devices subsidized if you wish yet still unlockable and the only branding to be found are a different SI than "generic", so I only suffer from delayed updates and nothing else

I bought a outright supposedly unlocked Xperia TX for a Sony Central store in Sydney then only to find out it was actually vodafone stock with a locked bootloader.

Hi, can some one help me out here.
I have a XZ which has unlockable bootloader. I have unlocked it and rooted and installed recovery kernal and Xperia Z Revolution rom. All ok.
Now, was just seeing if I ever needed to send phone off for repairs.
So downloaded the lastest flashtool and was successful enough to restore back to the 10.1.A.1.350 Original Sony Unbranded UK Rom.
With flashtool you can now lock the bootloader, so I went ahead and did this but now when checking the bootloader status, it says "Rooting Status: Unknown" and when entering my unlock code in CMD "Failed <remote: Command did not succeed>
How do I fix this so I can unlock the bootloader again?

I don't think your locked. You probably are still unlocked as we cannot relock bootloader yet

That's why I tried to lock bootloader after reading that.

Yeah, get the same error as in cmd.

Contact the dev. They might know more

Yes I will do, just need to get my post count over 10 before I can post in the development threads.
Don't want to bother people with PM's either.

Let me know how it goes. I was thinking of unlocking and relocking. Out of curiosity. Is your bravia engine working now that you relocked

Hi all.
First of all let me explain myself, I am a noob but not a total idiot so I am where I am through rational consideration.
I have renewed my contract on three UK, which has just expired. The number one consideration for me is that I have full, unlimited access to the internet with tethering and the only option for this in the UK is on three, on the contract I was already on. Three have an excellent 3g network and are in the process of giving DC-HSPA access and will get LTE-4g before the end of the year. I am guaranteed to automatically get the higher speeds when they are available, still with unlimited tethering at no extra cost. No other tariff can give me all that in the UK. There are sim-only options but they are all short term and do not guarantee me the unlimited tethering I require into the future, and there is a good chance the cost of these tariffs will increase when 4g is rolled out. In short the only option was to renew my contract.
So, I have renewed my contract and got the XZ. The XZ was the only option really after seeing all the developers struggle with Samsung phones and with all the developer friendly support promised by Sony. Whatever I did with my contract I wanted the XZ and I love it.
I knew when I signed the contract that I was taking a gamble on the locked bootloader, but the best option for me was to renew my contract and if the bootloader is locked sell the phone and use the money to partially fund the buying of a bootloader unlockable XZ. I knew that I would probably have to do this and was ready for it when I got the contract. Anyway the bootloader is unlock:no, so I will be carrying out my plan and this XZ will get sold to fund the purchase of an XZ with unlockable bootloader. I am OK with all that and if I sell the XZ for even half it's current value I won't care and will have still made the most financially sensible choice. I will have to buy a phone off contract, but I will still have the tariff I want. If the phone I have had come with an unlockable bootloader I would have been a couple of hundred quid better off, but I had to have a phone on the contract anyway so whatever phone I got would have had to go to get an unlocked XZ. Even if there was a tariff which gave the same allowances I would have had to pay for the handset anyway, and it would have ended up costing more than it is anyway. There is no such tariff anyway and I have made the sensible choice and am happy.
Now on to my question. Obviously I am working up to selling this phone, and figure it will be easier to sell sim-unlocked. Fortunately I live in the UK and network providers are obliged to allow you to unlock your sim. On three I have to wait thirty days and then they will unlock the sim for me. I have decided that the thirty days older the phone is will be offset by it being unlocked and being easier to sell. I am not in a rush to flash roms yet so I get the phone for a while and sell it for the least effort, hopefully when CM is pretty well ready for the phone.
Anyway, all is well and good and I am content.
However there is one possibility I have only recently considered. I am aware that sim-unlocking is a completely different thing than having bootloader unlockable:yes. But I was curious to know if a byproduct of getting the Sim officially unlocked by Three would be a change to the bootloader unlocking status. I don't know enough about how all this works, and as I say, I understand there is a difference between getting the sim-unlocked and the bootloader thing. But might the bootloader lock be somehow dependant on the sim-unlock status. ????
I only ask this out of curiosity.
I will find out for myself soon enough as I will be getting the sim unlocked ready to sell anyway. It will save me a bit of money and a bit of hassle if the bootloader becomes unlockable and I won't have to part with a phone I have become attached to and know is a good one, it doesn't have any of the issues some people seem to be having with their XZ's.
Either way in a couple of weeks I will have an XZ with an unlockable bootloader as CM has become a must for me.

[Q] Bootloader Unlock Allowed: No?

Hello all,
I haven't been able to find a straight answer in previous threads, so I thought I might ask for clarity.
It seems my Xperia SP has Bootloader Unlock Allowed set to No. The FAQs seem to suggest that this might be due to a SIM lock. My provider (Fido) offers SIM unlock that is covered under warranty for $50. Before I bite the bullet and pay for it, can anyone tell me if this will actually make a difference and allow me to unlock the bootloader?
Thanks.

It doesn't work all the time. Some phones have, but only a small portion. Mine is SIM unlocked, but I can't unlock BL. But, I'm with ya, I wish someone could figure out a way...I live in the US, but have a Fido SP, and they told me that they cannot unlock the BL. According to them, they do not lock any BLs for phones. But, obviously they do, since that's the only way it could be locked...

Just like both of you, I have this "brown" device. Locked by Sony, for unknown reasons.
Brown device are vendor locked devices.
Cursed I say.

Question about the bootloader

Hello, i'm considering in buy a brand new Z3C online (from my carrier discount program), how ever i can't use any device without CM13. I wonder if any Z3C can have the bootloader unlocked.. and if not, if someone have a way to unlock the bootloader without the Sony method.
I can't check if the device i want to buy can be or can't with the dialer code as it would be bough online.

Impossible to say, if it's a sim free network unlocked device they supply then there's a good chance it'll be unlockable. The only network I know of that supply sim free network unlocked device's for both payg and contract are three UK. Without checking the device before buying it's a lottery basically.

Thanks. In the past, my carrier was well know to be the only one in the country with unlock devices that they sell and contract free. I'll call then and ask if it still is like that (i think so).
Also, a guy said that it is possible to install custom ROM with a locked bootloader... far as i know it isn't true. I'm right, or this guy is?
