Bootloader - Galaxy S6 Q&A, Help & Troubleshooting

Will T-Mobile S6 have locked bootloader??? Will a T-Mobile work on AT&T LTE networks if sim unlocked???

Chainfire already confirmed root for the T-Mobile S6 and S6 Edge, which confirms unlocked BL. Time will only tell whether or not it works well with AT&T, though it likely will.

Correct. Tmo already confirmed unlocked, which means Sprint likely as well.
The big question is AT&T and Verizon... has a way been found to accomplish this now on Exynos?

T-Mobile Note Edge on AT&T.

I have been searching for an answer and have not gotten a clear and definitive answer. Does the T-Mobile Note Edge variant work on all AT&T LTE networks without issue after being unlocked? According to tbr Samsung website both models have the same bands with the t-mobile Edge have 2 additional bands
I have the att model but would really like to be part of the dev community. I have a week and a half to return my att model. I would buy the t-mobile model if it works completely on the networks. Anyone out there using a t-mobile Edge on ATT. Thanks

Think I can help answer a few Qs.
Am using a Straight Talk sim (ATT) in my T-Mo Note Edge. Getting 8-15+ mb/s down...2-4 mb/s up (more than enough for me). Followed rooting method posted by TekHD. Did not see unlock procedure for T-Mo Edge.
T-Mo does hold your unlock hostage for 2+ months or $100 (didn't see this stated and argued). Unlocked through a reputable unlocker through fleabay (~$24 I think - Tmo also recommended...go figure).
Hope this helps.
Wish someone can release a qualcomm kernel w OC/UV/governors and thermal control soon...

Yes, Using one right now. You do not need to unlock it at all it will work right out of the box with an AT&T sim as will all T-Mobile Phones.. This has been a thing for years. There might be some obscure T-Mobile phones without perfect LTE Band or Data support. Every major model will work perfect with absolutely no unlock don't waste your money. I actually called T-Mobile before throwing my gophone sim into the Note Edge T-Mobile variant and cautiously asked if they will blacklist the imei of a phone that is using an AT&T sim. The T-Mobile representative kindly, calmly, and with conviction said that no you will not have your device blacklisted, and that all T-Mobile phones should work out of the box on AT&T. Enjoy not paying for an unlock code! I'll upload pictures of my note edge running AT&T data services via an AT&T gophone sim if you don't believe me. It actually put the APN information in for me automatically too! Meaning I did not have to enter in carrier specific AT&T APN, the software on the Note Edge T-Mo variant picked up the different carrier and entered the APN settings automatically. Woot woot

strange. I have my att sim in a SM-N915T on 6.0.1 N915TUVS2DPG2 and it says network locked.

S6 region locked

Can anyone tell me if the phones is region locked? Thanks
i am not sure what you are looking for but i do know that there is a thread on here where someone tried a Verizon SIM in a Tmob and ATT S6 and neither one worked on Verizon.
Generally Verizon phones are SIM unlocked so u can use them on Tom or att but don't expect to get lte coverage since the phones have different bands enabled.

That's because those don't have CDMA radios, and at least the AT&T one is locked. Verizon phones come SIM-unlocked and work with other carriers. If you use a T-Mobile SIM you'll see an "unknown SIM" message, but it will work assuming the bands match. You should be able to get LTE with T-Mobile as most of their network uses band 4.
He means region locked, like usa

Anyway to get rid of this message? My g2 I had to root it to get rid of it. I hope I don't have to root the s6 just for that because it gets really anoying just having the icon showing unknown sim the whole time.

G930W8 with Verizon or T-Mobile?

I am thinking of getting an unlocked S7. It seems to me G930W8 has the necessary LTE bands for Verizon and T-mobile, which are the carriers used in our family. Does anyone have any experience with either US carrier? Is there any issue? I am picking this model mainly because it's not bootloader locked like the Snapdragon models (US models), so in the future I can load any custom ROM.

Did you ever get this phone and find out if it works on Verizon? I have rooted my G935W8, but my friend's G930W8 is unlocked and unrooted. I am trying to find out if she can use it on Verizon. The Verizon reps where she is says it will not work. She has just moved there, and needs a working phone. She was using it on T-Mobile, but that doesn't give her any service in the part of Utah she is now in. If she were somewhere she knew people, I would have her ask someone if she could test their sim in her phone, but she doesn't know anyone there yet.

Does Sprint version of HTC U11 works with AT&T or T-Mobile after unlocked?

Can anyone confirm that will the unlocked Sprint version of HTC U11 work with AT&T or T-Mobile? I chatted with both HTC and Sprint agents but not getting a sure answer. HTC agent said that even it's unlocked it will only work with CDMA carriers. The Sprint agent said it depends on the other carriers to be compatible with the device. Thus has anyone tested and confirmed it will or will not work on AT&T or T-Mobile? Thanks.
If Sprint unlocks it, it has the radios according to HTC's own specs page. There is no band 30 support for at&t on any model and there is no band 66 for T-Mobile on the Sprint model but the main bands are there.
The question is if Sprint will unlock it for domestic usage though. They have an inconsistent track record with that.
Sprints domestic unlock policy
or
unlock it yourself I have confirmed this method works
the US Unlocked & Sprint models have the same hardware, just different ROMs. I have only tested w/ a Verizon sim, but I am confident ATT & TMO will work fine.
if we had s-off, it would be even better, then you could flash the US Unlocked RUU
The hardware is the same on all models so it will work fine once you get it unlocked.

The hardware is not the same across all models. The Sprint model has a CDMA radio and does not support all bands the US unlocked version does but it will work fine on AT&T and T-Mobile.

I know for a fact the Sprint & us unlocked have the same hardware... No idea about overseas models

Purchasing Note 9 "unlocked" but cannot be used on Sprint?

Hello everyone,
I am looking to buy an Unlocked Note 9 (US Version) to be used primarily on the Sprint Network. I am looking at new phones on Ebay and Amazon and they are all labeled as GSM unlocked or some of them say GSM and CDMA unlocked, yet they all say they cannot work on the Sprint or Metro PCS or Verizon network. Some of the ads show that they have SM-960U1(unlocked) firmware some others show SM-960U firmware while still stating "unlocked", but I am not sure if they understand the difference or maybe I do not.
Aside for the phone being blacklisted on these networks, is there any other reason why a Note 9 would not work on these CDMA networks if they are truly unlocked? Thanks in advance.

If you're going to be using the device primarily on Sprint, why not get an unlocked Sprint version of Note 9? It is guaranteed to work on Sprint's network plus if it is unlocked, it can be used on other carrier networks.

Hello Droidriven, I am trying to look for this, but I am unable to. I have not seen any ads specifically stating Sprint Unlocked. Every unlocked phone whether GSM or CDMA unlocked states something along the lines, will not work on sprint or verizon or metro. If the phone is truly unlocked and supports the CDMA bands that Sprint uses, then what is the reason behind it?
I am wondering if I can just buy a Sprint only Note9 then flash the SM-960U1(unlocked) firmware for it?
I went through the same issues with sprint, got a note 9 unlocked from a friend an they said it is not compatible. So I asked about buying a note 9 unlocked from them. I asked what is model number and it was the exact same as the one I just got. I asked what is the difference between one from them and the note 9 I baught from my friend, They said no difference, EXACT SAME! Sprint Just wanted me and you to buy a new phone from them in a contract. The Unlocked model's have modems for both, CDMA and GSM. I was with sprint for 20 years, they were decent only for good deals, service was **** in Milwaukee. I left them for spectrum. No issues and great service. Sorry 2 years late..
