Hello,
I would first of all like to apologise for this long post. In January I purchased my Samsung Galaxy SII on contract from Orange. It worked fine and looked and behaved like (what I'm now guessing) is an unlocked phone (it didn't have any of the Orange apps installed and I had a lot more options). However, it started behaving strangely for the last month and to make a long story short, I received a replacement phone today.
The idiotic thing is that this replacement phone has a load of Orange apps installed (which I cannot remove!) and I noticed that some of the options I was used to on my old phone (Such as System Update) did not exist. I phoned Orange immediately to ask what the hell they had done, and they not only tried to tell me that my old phone probably broke down because I didn't have any of their apps installed, but also that my old phone should have had those apps installed. They even connected me to Samsung, even though it's not Samsung's start-up apps that are driving me insane (For heaven's sake, they even have the Orange logo at start up. It's not like I'm going to forget who my network operator is every morning.)
Anyway, after having read some guides here I've tried to root my phone and tried some SIM unlocking apps, but it seems to have made no change at all. I would have phoned Orange and simply ask them to unlock my phone, if not for the fact that I did that back in early July and they still have not sent me a bloody thing.
I am out of options and I am getting very irritated because I was used to the phone that hadn't been slobbered all over by Orange, and now I'm stuck with this limited thing (Can't even get the *#SIMLOCK# to work).
Does anyone have any suggestions?

and i suppose you are not rooted or probably you don't want to void warranty?
bcse there are few applications (root required) for simunlock
and do research first please...there is more than one post for this problem

I AM rooted. Like I wrote in the OP, I rooted it and tried some recommended SIM - unlock apps, none of which worked. I also did spend about 4 hours trying to research on this before I hit a wall, so yeah.

Post the links to all the guides and Apps you have tried.
1.get your arse over to sammobile and get the unbranded firmware for your phone/country.
2.next time buy an unbranded phone like I do.
Did you buy your original phone direct from orange, or via somewhere like carphone warehouse? CPW phones are unbranded even if you are buying them on a contract with a specific provider. Orange however always supply branded phones.

Hi
I'm looking at picking up a sgs2 phone from the three (3) store on a payg deal. I wanted to quickly check, I should be able to sim unlock this no problems right?
Also are there issues with debranding three versions?
Thanks

Think so
http://forum.xda-developers.com/showthread.php?t=1064978
mine came unlocked. what i'm more interested in is if we can have the original three firmware from someone, so that we can slap unbranded one onto the phone and then revert back if we need to (like bringing it back to three in case of a fault or something like that).
If you can sim unlock the SGSII which others have managed via that thread, then why wouldnt you buy the o2 payg for 399 rather than the 3 version for 499.
(At least those were the prices 2wks ago)
My bad, Ive seen theyve taken it off PAYG

Thanks All - I ended up getting one from Phones4U.
Turns out they have completely unlocked stock samsung devices without any bloatware. I thought this better than de-branding & unlocking etc.
Cost was the same, £499 but as it was stock I avoided the costs of unlocking etc.
ohmz55: Would like to have done this, but O2 stopped the deal.

O2 no longer offer it online, I was able to get one for £399 from O2 store just yesterday however. The guy in the shop did say he wasn't allowed to sell it on pay as you go but that he was just going to ignore that!
So I've been reading forums like every day since the 12th(launch in Canada), when I got my phone. So it's not like I came right on to ask questions without reading anything.
2 questions.
First is:
About half a week ago-a week ago I was reading about someone having frequent crashes and didn't really think much of it because my phone was working fine. People suggested backup and restore with pc companion, as well as taking it back to the dealer for replacement ect ect. Moral of the story is mine is now randomly giving me errors asking me to force-quit. like maybe 3-5 times a day? Is this common for an android device? Should I even be worried at all?(Not really sure what I should be expecting in reference to what other people are experiencing.)
Secondly:
So I've read a bit about debranding, would that be an option with a locked bootloader, and would that remove all of the bloatware shoved down my throat by my carrier? If so, which debranding pack(not sure on the terminology here=/) would be best to use if wanting to be as light as possible. Would a factory reset afterwards remove the debranding?
Extra Info: Unfortunately because Rogers in Canada owns the rights to selling Sony Ericsson's even purchasing the XpS directly from the Sony store(which I did)($500 Cad. +12% sales tax) limits you to a carrier lock via Rogers. (and a locked bootloader) Unit comes stock with .73.
Thanks in advance.
For second question answear is that you can debrand with locked bootloader with no problem (you just can not instal custom roms).
So far lightest would be Nordic software and personally I like to use UK generic where all unnessary apps can be deleted .
Factory reset would not remove debranding ( just resets settings and all of your customizations).
If you want to sim unlock your phone it is not difficult just order unlock code. I got mine for $5 from ebay, received code in one hour, now using it with fido.
Hmm you're with fido now? Wouldn't the unlock code be the be the same? Care to share?
Thanks for the information on debranding.
Sent from my LT26i using XDA
Unlock code depends on imei number of your phone.
I can share mine but it will not be accepted by your phone since unlock code is unique to each phone. Once you try to insert anything other then rogers sim card your phone will ask for unlock code, you have only 10 tries, after that phone will be permanently locked to rogers, so make sure you submit your imei correctly in order to receive correct unlock code.
In ebay just type unlock code rogers sony ericsson , the seller i used was freedommobile they charged me $5.49+taxx, see no point paying more then that.
Wow yeah.. I had no idea you only had like 10 tries. Can that be reset that counter via custom ROMing? I understand that custom ROMing sometimes unlocks, I was more or less asking out of curiosity.
Also.. If doing a factory reset wouldn't re-brand, Would doing a backup and restore via PC companion rebrand my unit? Or would that just restore back to the back to the base of what ever I used to debrand it with?
Uk Generic eh? Sounds like it would also be my cup of tea. I'm sure it's posted here, I'll use the search feature when I get home.
Thank you so much for your imput and follow up my friend.
If you ever want advice about digital cameras (professional/consumer) let me know, I'm a hobbist and sell them for a living. =]

Just turned on my phone for the first time today and started getting "Enter Network Lock Control Key." No service with AT&T. Huh?
This phone was working fine for the past two years without any problems but why now? I spent over an hour with AT&T and Samsung with no resolution. Said my phone was the unlocked international version so they couldn't offer any support and told me to "contact the original carrier" (there is none...).
My version is the latest stock Android ICS 4.0.4 XEU. Never flashed or updated or did anything like that to my phone. What now?

I have a GT-I9100 with the original stock XEU firmware that is now running ICS 4.0.4 stock. It's the original and international version. However, AT&T is my carrier. I bought the phone off of Expansys.
Update: Just tried in another SIM card from another carrier, and it still doesn't work. Also, I tried restoring the phone back to its default self by doing a full reset and still the same message. Now I know that it isn't a SIM issue but rather a phone issue. Strangely, my phone has been working for 2 years and suddenly decided to "network lock" itself on an unlocked/international phone.

Hello as this is my first problem with a phone/phone company, I'm confused. I am a long time T-Mobile customer. But my son gave me an upgrade phone cause I am apparently severely outdated. However it is an AT&T phone. A Samsung Galaxy S2 SGH-i777. He moved and now goes with Verizon. So I put the phone in my name by buying a $10 prepaid deal. However its now been over a year & 8 requests and AT&T continues to deny me the unlock code. The phone was never under a contract , it was purchased outright and was a gift a few years back from his father. Now my ancient phone ha taken a crap and I cant afford to buy another one. I have looked into several sites and became a member here thinking I was more edumacted :cyclops: then I am. I just really want to unlock the damn thing. Please help......This is what Ive done thus far.
1.) Updated to 4.1.2
2.) Downloaded and Installed Framaroot getting the SuperSU
3.) Downloaded CSC Select & SGS unlock tool.
Still no unlock code. Maybe I messed up already ..... idk? 2 months ago I was laid off, my savings is damn near completely dry and I need help.( In more ways then 1....bahaha)!! I would like to remove anything & everything regarding AT&T from this device and run Google or WHATEVER. Is that possible?? I Thank You ahead for any time, advice and help anyone can give. Happy holidays and Namast'e :good:
Unlocking is the easy part:
a) Get the relevant information from your son, and use this AT&T website.
OR
b) I used Galaxsim unlock, and have used my i777 on other carriers (not t-mobile), and overseas.
Using the i777 on TMobile? I'm not sure that will work very well.
-The i777 GSM frequencies [850, 900, 1800, 1900] will not communicate beyond 2g on t-mobile network.
EDIT: Apparently T-mobile has refarmed a lot of its 3g+ services to the 1900 frequency, which will allow the i777 to communicate at full speed on t-mobile service. *assuming the relevant refarming happened in your area.
You want to use a de-branded, slimmed down version of the firmware? No problem.
If you like the touchwiz interface, look at cooked or shostock.
If you would like to run an AOSP flavored firmware, then there are several excellent choices in the development forum.
Happy flashing,
-Cyril

Does anyone here know if the T-Mobile variant has a locked bootloader? And if so, is there any way to unlock it?
I'm wondering the same thing...I'll be going to look at it later today. Also I noticed the wifi model has the phone dialer installed so I'm wondering if the LTE T-Mobile model has phone function with the right sim installed?
I went to the T-Mobile store to look at the tab...They had no idea if the bootloader is locked or not. I'm sure it probably is but haven't seen anything about whether it can be unlocked yet. They also told me that the phone and SMS/MMS might work for a few days until the system detects it is a tablet, then those functions will be disabled. Make no sense to me why we can't have those functions on a tablet here in the US...And why even put the software on the tab if it can't be used? I told them to keep it and I'll get the WiFi tablet and just use the hotspot on my phone when I'm out and about. At least I'll get quicker updates (Maybe because Samsung) and I won't have the tons of their bloatware on the thing.
Any feedback?

If you can go into store and view the tablet go into settings and enable developer options by tapping on the build. Then go into developer options and see if there is a switch to unlock the boot loader. I just bought the wifi model from Best Buy and the boot loader can be unlocked. I have already installed TWRP and Magisk. I think maybe the LTE version may require a 7 day wait not sure.

from almost a year back-wondering was your wifi device branded like Tmobile or Verizon? sad to see no continuity in the thread-was hoping for someone to check out the lte device in Tmobile to see if it could be unlocked or if the option was there-not many resources on internet. Does Tmobile even carry this thing anymore? thanks

Unfortunately, I think I'm being held back by the whole 7-day oem-unlock hide thing. And all the ways around it have apparently been patched by samsung. So this time next week, I'll know for sure. As of right now, I believe it can be unlocked, but I don't know for sure.

thank you so much-well I will be receiving my device tomorrow. So let the race begin-ha ha kidding will see and compare. I did not know Samsung has this 7 day wait period (like Xiaomi has a 2 week period). Oh well, time will tell Thanks for keeping me posted and do let me know what you find. I did see a post somewhere on xda for the tab s6 where the poster said he could unlock the carrier device (think it was Tmobile) but he wanted to find out if he could root it. I will find the post (again it was an old one and of course, my response (recently) has not got any response. In fact, like many, he did not follow up with any posts thereafter (several months back).

Hello Arudis I got a used Tmobile variant. But I do not see any OEM unlock option in developer settings (a prerequisite before anything can be done for unlocking b/l). Which software version is yours having? (maybe it is different because you bought directly from Samsung but does not make sense if it is branded Tmobile). Could be that you have an older version of Android-appreciate if you could let me know which software version, CSC etc yours has. I might end up returning mine if there is no progress. Thanks.!
EDIT: Returned it. Great price and condition. Just too bad-did not want to take chances with it. Good luck-seems that you should be able to unlock it per that other post I sent.

Well. I'm struggling w/ it. CSC was TMB btw. This whole ordeal has been a mess of mistakes on my part. If i can't get this unlocked in the next day or 2 then i'll be returning it myself. I'd rather have a weaker tablet w/ root and a custom rom than a great tablet that i have to run stock.
Current software version is T867USQU3BTJ1 / T867UOYN3BTJ1 / T867USQU3BTJ1.
First thing I needed to know was whether or not I could unlock the tablet for other networks and in order to do that, I inserted a sim and logged into the tablet w/ my google account. I think this is where I made my first mistake as I have a sinking suspicion that inserting the sim somehow got rid of my oem unlock toggle. I know I had seen it before I started trying 2 unlock the sim because its always the first thing I do when I get a new device. But between the sim and the unlock process I ended up rebooting too many times and it auto-updated itself to the latest firmware. Since the latest firmware, I haven't seen that toggle at all. When I try to flash twrp w/ Odin, it fails.
@ this point I've decided that I will never buy another samsung device ever. I've had all manner of fun rooting every other device i've ever owned that wasn't a samsung device, however every samsung device has always been a supreme pain in the butt because I can't just do what i want w/ adb and fastboot.

I agree but this has more to do with (if not entirely) to U.S carriers playing games with dual devices for marketing-only here does this go on, where the carriers since time immemorial have blocked calls and texts on tablets (7 and above inches) giving some bs reasons (there was a time they had this tablet "plan" and phone "plans"-those have at least merged at least for Tmobile-otherwise their servers would detect a tablet and switch you automatically to a tablet plan for your 'convenience' and maybe even 'safety' lol)....so as long as they do this, Samsung (even Apple which does the same thing worldwide anyway) have tablets that do not have phone-like functions (Samsung has this call and text pairing with other Samsung phones a.k.a buy two of our devices please AND have two plans (so both Samsung and carriers win)...) on their U.S devices (Samsung at least to their credit have this :"unlocked" cellular variants in rest of the world, Apple does not even have that-yes, I know there is Google talk and all kinds of wifi-based workarounds but that is a different topic.
EDIT-if you compare the older devices like say tab S and tab s2 (the carrier variants and the international variants you will find out that even the speaker arrangements are different. I delved deep into this and found that even the boards were different-the lengths they went to do this to keep the versions distinct is amazing!) folks here on xda etc kept thinking for a while that they could simply flash the international ROMs (never mind the b/l block or hurdles) but the partitions were not even the same let alone the modems, and the actual hardware itself!
So blame the carriers-I do. So I never get these carrier devices (first time I tried my hand at it-no more)
Having to perform a soft boot tonight I noticed an "unlock bootloader command" in the softboot menu along with "cache clear" along with the always present "factory reset". Which I have to perform anyway because network mode locked to 3G only and no option to change it back so it has major conectivity issues. I'm thinking I may try the unlock bootloader command.
P.S. Mine is the tmo version

Out of curiosity which model number is your tmobile tab s6 lte? I have the verizon sm-t867v model which i re-flashed to the tmobile sm-t867u model using modified Odin 3.14. Unfortunately the bootloader remained locked down with no way to unlock it. Also what is this softboot menu your speaking of? I know samsung like the back of my hand and I've never heard of a softboot menu. Curious if this is something new im not aware of since I've been stuck with verizon brands the last 3 samsung devices I've owned...
Yes and Yes!
Can someone clarify something on the Tmobile Variant of the Tab S6?
This T867U definitely comes with the HARDWARE to text because i got it to work but it stopped.
So could this just be a matter of getting it 'Carrier Unlocked" so TMO cant decide what we do with our tab s6 since its payed for???

I have the same problem, I bought the device from eBay and now in Egypt, the device is locked to the T-Mobile network, and I don't know a way to unlock it. I cannot contact the seller to ask him about the T-Mobile subscription details, and after communicating with T-Mobile, they did not reply
