[Q] Active simlock on TF300TL from AT&T - Transformer TF300T Q&A, Help & Troubleshooting

I came into possession of 4G/LTE tablet Asus imported from the U.S., but not everything is as it should be.
Namely, it turned out that the tablet is sim locked for AT&T. I searched XDA far and wide and have not found a way to remove it (unfortunately not as easy as in the case of telephones).
Due to the fact that I work in a computer reseller company I have access to a unlocked version, which is not sim locked.
And this raises the question:
Is it possible (with app or via adb) to clone (1:1) a file system from unlocked one and put it into locked one? Whether it make a difference?
I'm not asking if changing ROM will remove sim lock (cus it won't) but there might be some important files that contains information about sim lock which after replacing will do the trick

Are you sure? Con somebody confirm that?

Anyone? I'm in the same boat.

You can't. My boss had Dell streak locket to Vodaphone and changing ROM didn't help. He had to receive SIM unlock code from Vodaphone.
Besides that, if you live in USA, unlocking SIM is illegal from one month ago. Best option is to trade locked for unlocked one.

Only illegal if it was purchased new, after that law went into effect...2/1/13 I believe.

There have been like 4 or 5 different threads here all asking the same question:
No so far there is not a working UNLOCK solution (other than maybe getting a very understanding CSR at AT&T. Maybe just maybe if you told them you were traveling to Mexico/Canada and wanted to use a local Pay as you go data plan...then maybe...but probably not)

[Q] SIM Unlocking [smart]phones nowadays

Hey, everyone!
I was perusing the forums for sim unlocking an HTC 7 pro. Many years have passed since I adquired my 8125, and it is still serving me faithfully. Yes, it is still working
Back then we just had to flash the roms, I think the radio part did the trick, and then phone was thus unlocked.
But the couple of hours I spent today looking for some insight only led me to 3rd party sites which charge money for sim unlocks. Those require the carrier to be mentioned in order for them to provide an unlocking code. So I can't just buy a phone off ebay and expect to get a code from those sites. US cellular, for instance, is never listed on them. Besides, $25 is not bucks where I live >.>
Is that really how SIM unlockings are handled here now, or have I just been really unlucky with my skimmings and searches?
TYVM, have a great day!
I believe there is no free option in order to get the HTC 7 Pro unlocked, unless you can get the seller to call their cell phone provider to get the code. Most, if not all, windows phones don't have a free option to unlock but I could be wrong on that. But if you already have a HTC 7 Pro I think you're gonna have to cough up some cash and use some unlocking websites...
Well, thanks for the straight answer.
Oh, no, I don't have one, yet. I was thinking of Buying one off Ebay, used and locked. It is harsh having to pay for switching carriers, but maybe that is what they had intended with their locking in the first place
Hmmm. Do you know, by chance, if this is the norm for smartphones recently, not being able to sim unlock them at home? Or is this device special for that matter? or was it not popular enough to tinker with it?
TY, again. Peace
I wouldn't say your device special in regards to that, all phones come SIM locked. Its just some android phones are easier to unlock during the process of rooting phones. I know for my old HTC touch running windows, it was easy to unlock since you basically had to move a couple files. I think windows 7 in general makes it harder in general to unlock as opposed to android.

How can I tell if my NS is unlocked or not?

Hello everyone.
I just pulled the trigger on a Nexus 7 32GB and I want to sell my LNIB Nexus S i9020T to help pay for the N7. I have its original box with all original accessories, including the original screen protectors still on the screen. This phone was never activated, nor was the T-Mobile card ever taken out of the box. So, I have no clue if this means it is unlocked or locked to T-Mobile. I assume this also means the ESN is considered clean, or is that IMEI?
I would like to put it on eBay as "New Other" LNIB, in Mint condition. But I noticed other sellers are advertising theirs as "Unlocked". Is there a way I can tell if this is unlocked also? Or can I unlock this easily? Is it worth more as unlocked? I have no history on this device as it was purchased by my sister in law (ex) brand new, and she was going to give it to her son Jason last year but instead he got in serious trouble (with the law) and she decided he was not deserving of it anymore. So she gave it to me as payment for working on her computer. I was the first one to ever open the box and play around with it. However, I simply do not need another mobile device laying around here unused.
So, how would you list this if you had it for sale? unlocked or t-mobile only? How do I know the ESN is clean? just because the phone never had a sim card inserted? I never sold a Android device before, so kinda worried that I might get the description wrong if I list it as unlocked with clean esn (or is it IMEI?). Any tips would be appreciated.
Thanks

Pick up SIM card from another carrier and see, that's the simplest way to find out. If u get message for network unlock code than it's locked on T-Mo. Originally, i9023 or i9020 were sold unlocked, but i am not so sure about i9020A or i9020T versions (AT&T and T-Mo).

Very good idea. Maybe I can try my current AT&T sim card from my other phone? By the way, I just noticed that when the device boots, the boot screen shows a "Lock" under the word Google. The lock is an icon and is in the Unlocked position. I just now noticed it, lol... I wonder if that means what I think it means... I will still try the sim card though. Thanks
All Nexus S are unlocked. HOWEVER, they are frequency limited (tri-band vs Galaxy Nexus penta-band).
This means that on some carriers, depending the frequency they use, you might not get 3G or signal at all if they don't operate a 2G service.
The lock you see when booting just means it's fastboot unlocked, so you can flash custom recoveries, roms and so on. Nothing to do with the network.
IMEI would be correct in this case. ESN is generally only used with non-GSM phones (Sprint, etc), AFAIK.

Ah, thanks for the clarification on that icon. OK, so it seems the word "Unlocked" is just there to let people know it may or may not work in 3G on there own network due to frequency differences. Gotcha.
Now I feel confident I can list this with an accurate description. Thank you!

Thanks for the clarification on that. Yeah, there is a clear IMEI sticker on the box and a IMEI sticker under the battery. I assume since this phone has never had a sim inserted the IMEI on this device can be used anywhere legally, right?

To my knowledge, inserting a sim into a carrier unlocked phone doesn't suddenly lock it (legally, contractually or via software).

That's what I thought to. However, I am just making sure because, if I sold this, and then found out the buyer could not use it I would be liable for making it right (I hate refunding). My ratings at eBay is still a perfect 5.0 out of 5.0 at 100% positive feedback and I do not want to give someone any reason what so ever to give me negative feedback of any kind. lol I guess I am being overly cautious.
Thanks Nomedias :good:

[Q] Sim unlocked, anyone?

So, I have an Xperia Z3, D6616, stock, locked bootloader still, and I'm considering sim unlocking the device for use on AT&T. Bought it on craigslist. It's currently locked to T-Mobile. Most unlock websites say not to purchase the unlock code for the device if it is locked to T-Mobile due to an unlocking app that T-Mobile installs on handsets that prevents third party unlocking. See attached pictures. I'm an AT&T customer, so this is a bit of a pain for me.
Called T-Mobile, they will not unlock the device as it does not meet the requirements. I'm not a T-Mobile customer either, so there is no account history associated with this IMEI. I have a feeling that someone bought this device at a subsidized price, sold it new in box, and pocketed the cash. Now I have a fancy T-Mobile MP3 player and digital camera that won't play nice with my AT&T sim....
Has anyone successfully unlocked this device for use on another GSM carrier while originally being locked to T-Mobile without going through the carrier's unlocking process? If so, what website/service did you use? I'm considering selling this thing as it's a bit useless on my network thus far, being locked to another carrier and all.
Thanks in advance.
is this me being a bit daft, but could you not simply put an unbranded firmware on the device via ftf and simply unlock the device via a website?

I'm not sure if that's a possibility. There is no root for this device without unlocking the bootloader, which wipes the TA partition and causes you to lose the DRM keys and cripples camera functionality. I'm trying to avoid unlocking the bootloader for as long as possible, but if unlocking, rooting, and installing a custom ROM will assist in sim unlocking, it may be in my best interest to do so.
I'm trying to do a network unlock with a code and keeping the phone stock if at all possible, at least until a root method without unlocking the bootloader is found, if it ever is... I just need a way to get a code for unlocking WITHOUT going through T-Mobile.
you don't need root to flash an unbranded ftf., once done then simply use a website and buy the unlock code, with the tmobile firmware out of the way there shouldn't be any interference in terms of network unlock.
what i am saying is:
1: flash global unbranded firmware via flashtools with ftf
2: buy your network unlock code
3: enter code as no t-mobile firmware is available on the device anymore to interfere
i am not saying this is possible as i do not have a t-mobile - us device to test, but my vodafone branded z3 has had an unbranded firmware flashed by myself with no root.
i hope this helps clear up any confusion.

I may try this tonight.
If I flash another firmware with flashtool, can I return to stock after unlocking without root access?
Rooting and/or unlocking the bootloader or flashing a custom rom or a different firmware has absolutely nothing to do with SIM lock.
If you try and sim unlock by doing any of that you are wasting your time.
Best bet is to go to your carrier and ask them to sim unlock it

Yeah, that has been my experiences in the past. The carrier always did it for me. But T-Mobile will not unlock this device as it does not meet eligibility requirements, and the unlock websites say not to buy a code for a T-Mobile US locked Z3. I need it unlocked for use on AT&T. I remember unlocking HTC devices with SuperCID and unlocking Samsung devices with dialer codes. Anything like that for the Sony side of the house? this will be my first Sony phone.

Not that I know of. In the UK you can get any phone sim unlocked on any market stall in a few minutes for a fiver. Its not really to do with the phone but the carrier and the laws you have over the pond.
Simply try a websites unlock, I do not believe T-Mobile can block carrier unlocks. Who has told you otherwise?
See the attachments in the OP. The unlocking websites are saying not to purchase the codes if you have a T-Mobile US locked Z3. I don't want to waste $40, especially when there are no refunds, and want to know if anyone has successfully unlocked with a website and NOT the carrier.
D6616 has an NOT unlockable bootloader, so that method is a no-go.
If it was on EIP and they sold it, the phone may be blacklisted by T-Mobile already
I don't believe you can flash a different version firmware, for multiple reasons, one of which is because it's a D6616 and not a D6603
The T-Mobile SIM unlock tool does work if all conditions are met.
Good luck OP, I think you might have a difficult time with this one

Again, the bootloader status has nothing to do with SIM lock.
Flashing another firmware will also not effect sim lock.
I'm seriously considering selling this device and going for another bootloader unlockable handset due to this unlock headache. T-Mobile is no help for unlocking this IMEI.

Sorry for the first line, didn't mean to get that wrong. Definitely agree that bootloader unlock and SIM unlock have nothing to do with each other.
Called T-Mobile again, tried to unlock. No account number to tie unlock request to since I use At&t as a carrier. They recommend I call Sony directly and ask for an unlock. I did, Sony told me to contact the carrier again. I do, and have the T-Mobile rep call Sony guys on a three way call. I explain that I purchased the device on craigslist, not a T-Mobile account holder, I'm an active duty military member, phone was several hundred dollars, I didn't know... boohoo, I'm dumb, I should have purchased from Sony, No moneys to get a new phone since this was so expensive, etc. Sad poor me story, you know.
Sat on hold for a bit, but Sony caved and said they would attempt a remote unlock via code, but it would be between 1-3 days and the reply will be via email. Time will tell, now. Just waiting to see what happens. I hope it works. I had to have the situation escalated to the third level of supervisors to get this far...
sounds like good news, if that fails, you could ask someone you no on T-MOBILE or a family member to give them a ring and pretend its there phone, should also do the trick
That's a good idea!! Thanks for that. I'll find someone at work who has T-Mobile and go that route if I need to.
any updates.. i badly need my T mobile Xperia Z3 to be get it unlocked...
Sadly, there is no update. T-Mobile will not unlock the device unless I use it on their network for 45 days, ahve an account in good standing, etc. This isn't going to happen, as I am an AT&T subscriber. I have the Z3 listed for sale on craigslist. Awaiting a sale or trade. If anyone wants to swap phones for a still in the box T-Mobile Z3, let me know. Looking for an S5, G3, or Nexus 6. Gsm variants only. Too bad, cause I really like the Z3. I would keep it if I could sim unlock.
Is the unlocking app based off the Sim card? Cause I bought my tmo Z3 3 days ago. Used my Sim from my moto x. After I got everything set up I tried the permanent unlock which was successful.

How to unlock a carrier locked phone

I would like to buy a carrier locked phone in the USA.
I do not live in the USA so my question is, can I take this phone home and then flash a new ROM on it?
Would that take care of the lock?
Thanks!

Hi There,
Well Unlocking the Bootloader of your device Unlocks it to any Carrier.
If you want to know how to do that tell me which device you are using.

Again, it depends on the phone and the carrier. Verizon phones are internationally unlocked out of the box. Which means if you buy it and try to use it in the US without unlocking it, it won't let you, but if you take it outside the USA, it's GSM unlocked. AT&T and T-Mobile phones can be unlocked and used globally too, but both require that they've been used with their service for a time. 40 days with T-Mobile, and with AT&T it has to be coming from an active or a prior account.
With AT&T and T-Mobile, you can purchase (through eBay or websites) unlock codes, which run like $30-40 for a flagship phone. Alternatively, you can buy new unlocked phones off eBay that once locked to a network, but the reseller bought the phone new, opened the box, unlocked the phone, then sells it. Or you can buy a used phone that has already been unlocked.
Don't buy a Sprint phone, it won't work.
IMO your best bet is to buy a Verizon "world phone", or buy a factory unlocked "international" version.
LTE bands are another matter. If you want LTE where you'll be taking it (assuming it's available), you might be best off with a Nexus 4 or 5, or a recent Sony Xperia Z - class model, as these have numerous LTE band compatibility.

Thanks for the info, but my question was how to bypass the locks on the phone.
I know I can buy it unlocked but it's way more expensive.
I thought that the lock was software related and not hardware so that burning a new ROM would fix this.
Is that the case?

[Q] Unlocking a SIM Locked AT&T Note Edge

Hello All,
I'm newbie in Unlocking and Rooting the Samsung Galaxy Note Edge. It's my brother's phone and he sent it to me from US to Egypt, I need now to unlock the phone and my question is,
If I Rooted the phone and unlocked the Bootloader and Flashed a Custom ROM, will I be able to use any SIM card? Or I have to Unlock the phone using the Unlock websites for 29$?
Thanks in advance.
Currently, there isn't a way to root the AT&T version of the Note Edge. The answer to your question is yes, if your are able to unlock the bootloader and flash a custom ROM, you would be able to use your SIM card.
I wouldn't trust any of the websites offering an unlock or root services but that's just my opinion.

Care to provide the information so that we can also do it?
And love the replies that are sarcastic in nature.
You've posted more than I have, and all this time you don't know that you can buy unlock codes from various places? It has been discussed to death in the forums.
Anyway, since you want to know, I'll help you out. I bought my code from cellunlocker . net. You need another SIM card that is not your network, plug it in the phone, and the phone will ask you for the unlock code. Put in the unlock code that you bought from the place that I mentioned. Viola! It's permanently unlocked.
