Device unlocked after being paid off, now what can I do? - T-Mobile Samsung Galaxy S8+ Questions & Answers

I'm wondering now that my device is unlocked, what can I do with it? With the bootloader still locked, I can't install a custom ROM, I don't have any desire to switch carriers, so what can I do with an unlocked S8+?
thanks in advance.

If you have a SIM card, the phone will accept it and give you service....

[Q] Rogers SIM-Lock

Hi, I'm brand new to this kind of stuff. I've done some searching around, and I have come to the conclusion that I am one of the unlucky Rogers customers with a Play that is SIM-locked I can't unlock the BL.
I've seen the methods that Jinx and others have come up with using SETool but I was wondering if, since the SE site explains that my phone is SIM-locked, I could pay one of the unlocking companies like theunlock.ca and remove the lock from my Play.
Maybe this has been asked before, but after I remove the carrier lock, could I access the BL?
Nope, a sim unlock is just that, a bootloader unlock on the other hand will grant you access to fastboot and sim unlock your phone, although its a little more expensive.
Yes you can sim unlock your phone with a simunlock company. Mine cost 8 bucks to do. Bootloader will still be locked but who cares. The best roms are the stock ones anyway and there is no risk bricking your phone.
I have a Rogers Xperia Play; How can I tell if mine is SIM-locked, or are they all SIM-locked?
All roger xperia plays are sim and bootloader locked coming from rogers, to test out the sim lock just grab a sim from a different provider and pop it in (it wont work). As for testing the bootloader, turn off your phone, hold the search button and plug in the usb cable to your phone and computer, if it was bootloader unlockable your status LED will turn blue meaning you can use fastboot, if not, nothing.
My phone also came from Rogers, sim unlocked from some website for 8$ too.. I still have locked bootloader.. But I think that you can unlock your BL yourself if you already have an unlock sim phone.

There is someone unlocking the rogers bootloader.

U can get root by installing the original uk firware, ginger break, up date ota and you have the lastest firmware.
Hope this helps
Thats an expensive route to sim unlock though
wait so let me get this straight.... I have the r800a rogers branded simlocked phone.
If I were to pay someone to debrand it which is = sim unlock (correct me if wrong) , then I'll be able to unlock the bootloader myself right? or aka access fast boot.
JNo you can sim unlock but you will still be locked out of fastboot as it is factory locked. Here are your choices,
Sim unlock is 8 bucks
Or
Bootloader and sim unlock is about 28 bucks
Or
Unbranding is free, just flash a stock r800a generic rom

Can I view unlock code after it's unlocked?

Is there a way or app that I can use on this phone so that I can view my SIM Unlock Code AFTER the phone is already SIM Unlocked?
I ask because I bought two of these phones unlocked and would like to have the Unlock codes saved just in case I need them later.
Somehow I seem to have messed up or lost my unlock on one of the phones after I rooted it and flashed a new recovery / rom.
It was unlocked, now, If I put an ATT sim in it asks for my unlock code again and I do not have it, as the phone was unlocked when I got it.
Though, when I press *#7465625# to it says all the locks are turned off, like my phone should be unlocked?
Any idea why it is asking for my unlock code again, and if there is a way to get around it being that the phone was unlocked?
Is there a way to recover this unlock code?
Thanks guys!

Currently there isn't a way to view the code. Several of us have been digging through the system of the device to see where it's coded too. the thread here is where it's being conversed about. click here
How do you know for certain the phones were unlocked when you bought it? Did you try swapping Sims before you flashed anything to it?
I have mine unlocked and have flashed; two roms, cwm, a radio, and a few mods......still unlocked. I constantly swap Sims between my crap work phone and my Samsung, always works.

The person I bought both phones from told me they were both unlocked.
The first one I tried worked, the second one I never tried an ATT Sim until after I rooted, flashed, etc and then it wouldn't work.
He emailed just emailed me the Unlock codes for both phones and they work fine.
Either way, it's all good now. Thanks for the help guys!

[Q] Carrier Unlock Question

Hello. recently I read on a section of the HTC One X forum that if you want to unlock the carrier of a HOX and you have a custom ROM flashed and bootloader unlocked you need to lock back the bootloader and flash a stock ROM. Is it true, or can unlock it with the custom rom flashed?
You can`t disable the carrier lock without s-off.
Thanks for the answer. So there is no way someone could unlock the carrier if i have S-on?
No, sorry....
There is no way without S-OFF.:angel:
You can unlock your carrier to allow different network Sims, just google "HTC one x carrier unlock".
It's not possible to change your cid without s-off

Here comes the problem.. I know that cellunlocker.net is trusted when comes to unlock codes and i got my code yesterday. I was on Custom ROm with bootloader unlocked. When i enter the code it says it's incorect so that's why i need to know if i need to relock the bootloader and go on stock rom?
I had the same situation.HTC locked device with the code you can find on websites but then your carrier changed unlock codes,and the one you bought from site is incorrect.
I asked my carrier to tell\sell me the code but they dont want to untill the warranty is over.You can ask your carrier also,it doesnt cost you anything
My local phone repair service tell me that only solution for me is to take apart phone and read codes directly from motherboard but then i will lose warranty,which is ok for me,i already unlocked bootloader and root my hox
Just relocked and flashed stock rom. I will contact the carrier and try to get the code. Thanks for the help.

If i unlock my branded phone, will i be able to unlock bootloader?

So, i have a branded phone and can't unlock the bootloader.
Will i be able to unlock the bootloader if i unlock my phone by contacting the phone network operator?
Also, will these two options do the same thing with my phone?
unlock at: phone network operator
unlock at: http://unlock-bootloader.com/unlock/

Removing the SIM lock (which is what you appear to be referring to) does not give one the ability to unlock the bootloader. However, I believe unlocking the bootloader will also remove the SIM lock. I can't say for sure, since my version of the Play (R800x, the Verizon CDMA one) does not use a SIM card at all.
Thanks for the answer!

Rooting Unlocked Phone Question

I have an ATT phone currently unlocked and using it on T-Mobile. I want to root and use it on T-Mobile, but Im a little nervous that once I root, and wipe everything, the phone will be re-locked to ATT. So my question is, once I root will I lose my carrier un-lock?
It might be helpful to clarify a couple of things. It sounds like you're currently SIM-unlocked (thus able to use your AT&T branded M9 on T-Mobile). Are you currently bootloader-locked and want to unlock it so you can root? Or are you already bootloader unlocked?
Rooting definitely does not wipe/re-lock anything. Unlocking your bootloader triggers a system wipe. My understanding is that once your phone is SIM-unlocked, system wipes don't affect your phone's SIM status.
Sorry for the confusion. I am currently sim unlocked, and I want to bootloader unlock. However, before I unlock my bootloader, I want to make sure that I wont re lock my sim. My ultimate goal is to unlock bootloader in order to root, but I dont want to relock my carrier to ATT. Yes, it is an ATT phone and I'm using it on T-Mobile.
I'm pretty sure that unlocking the boot loader will not affect your SIM-unlocked status.
But if it were me, I would want a more definitive answer than that.
Another forum member may be able to answer for sure. In the meantime, consider asking HTC directly via their chat system. I've found them friendly and straightforward.

No you won't lose your unlocked network status.
The unlock once done is permanent.
There was one a while ago on the s3, an app, which was unofficial and I lost that a few times between flashes, but I don't think you'll have that issue.
Thank You. Unlocked boot loader, rooted and still have sim-unlock.
