Help converting SM-G935P (Sprint) to T-mobile/Unlocked status - Samsung Galaxy S7 Edge Questions and Answers

Alright, I purchased this phone off of a friend who discontinued their service with Sprint. Their account was in good standing, and they'd had the phone on the account over 50 days, so it was eligible to be unlocked. I currently have a Nexus 6, which works fine, but the screen is shattered. I wanted to use the S7 EDGE while I get the screen fixed on the Nexus 6.
I've called Sprint on numerous occasions, and they've 'unlocked' the phone; however, when I put the T-mobile SIM card in, I get invalid SIM. I've tried factory resetting with just the T-Mobile SIM as well, and I get the same result. I did some research online, and talked to some people, and I got mixed responses. I've heard that you can't use a Sprint S7 EDGE on T-Mobile because one's GSM and one's CDMA. However, I've also seen that some people have success in using Sprint S7 EDGE on T-Mobile.
I did a bit more research, and I saw that some suggested flashing the SM-G935U ROM, which is the unlocked ROM for the Samsung Galaxy S7 Edge. I tried this as well using ODIN, and still get invalid SIM.
Can anyone please provide some advice on what steps I need to take in order to get this unlocked? I've spent a lot of time researching this on the internet, and still haven't found a clear solution to what I'm encountering.
Thanks in advance for any help!

Sounds like the device is locked. So therefore you need to use a 3rd party unlocking service, or if you have access to a z3x box then you can perform the unlock yourself :good:

Try these guys - www.cellunlocker.net. I've been using them for a long time and they've always come through for me.
Sim-unlock.net
Did mine last night
i have used cellunlocker.net before and they have been 100% able to unlock what i had. i even made the mistake of buying twice for some reason but they refunded me the 2nd one without me even asking. it's the new tmobile unlock app i havent tried yet. i tried getting them to unlock my tmobile s6 before but after a day or two they said they couldnt do it because of the new system and refunded me and i never tried again. but looks like they figured it out for the s6. i would try it but there is no way for me to test if it works. every sim i have and can borrow is tmobile
I wanna buy now a Sprint, Galaxy S7, and use it on the Verizon network, because Verizon has less capabilities to play around with software. but Verizon is still the better service, so I wanna stick to them, so does anybody know if Sprint still locks their LTE phones? And will it work 100% on the Verizon network, and how will it work internationally on the GSM network, can someone please educate me in this Subject?
Try this service: www.unlockradar.com if you want to unlock your Glaxy S7. Customer support is very responsive and they can asist you at any time.

SM-G935A sprint need to work with t-mobile

I have aquired a Samsung Galaxy s7 edge from a friend for cash instead of having a equipment installment plan through t-mobile. Currently using a note 3. But wanted to upgrade.
Ok, so my biggest dilema, I have the s7 edge that had a sprint logo on the back, and when started, the sprint logo and theme comes on. I insert my sim and it is network locked. I did some research and found that I have to have a network unlock code. So I buy one from unlocked.com. The code they sent me didn't work. Then they sent me more codes to try. Needless to say, none of them have worked. I've been trying to unlock this phone for a week now. Is there a way to install a factory samsung rom that would boot the phone like a factory unlocked unit?
Any help would be appreciated! Thank you
I am pretty confident there is no workaround as the cell radio inside a Sprint Phone will not communicate on Tmobile towers. Tmobile and AT&T work together and depending on the phone Verizon phones will work once unlocked on AT&T and Tmobile.

Yea, just putting in a code won't work. You have to either get it unlocked by Sprint directly or through a third-party service that will remotely connect to your phone from online.

I need to unlock a S7 also. I'm from a diffrent country, I believe the phone is from England, but don't know what cell provider the phone is from.
Can I still unlock it via a third-party service?

SIM not working for Verizon

Bought a Note 4. Says the phone was for GSM. I was going to use it for T-Mobile. When I got it, the back cover said Verizon on it. I thought it might be a replacement back. Tired my SIM to no avail.
I tried to sell the phone to a Verizon user and they said they couldn't connect it with their SIM either, even after Verizon support.
Does anyone know what steps I can take here so I can fix/sell this phone so I can buy a T-Mobile model? Thanks.

How to unlock my sprint g930p for T-Mobile network.

I have my sprint locked galaxy s7 sm-g930p but recently switched to t-mobile. The phone i was using on t-mobile broke today and I need to get my sprint s7 working for the t-mobile network if it all possible. What would be the best way to get this phone working a different network? I've seen posts about unlocking services but they seem like they might be a scam and I've also seen about flashing the unlocked versions firmware onto the phone but im not sure if that would even unlock the sim or not. What is the easiest way to go about unlocking this damn phone?
Thank you for any help on this.

Desperate: Is there any way to unlock a blacklisted Samsung S7 from T-Mobile?

Hello all,
Like many others, I unknowingly bought a blacklisted phone on eBay. It's a Samsung S7 with T-Mobile from the US. I live in Costa Rica, and I'm trying to use a SIM from a local service provider. Sending the phone back for an uninteresting list of various reasons is impossible at this point. So, I am attempting to unlock it.
I rooted the phone with SuperSu thinking that would work, now I know better. After hours and hours of research, I found a xda dev that can remove the lock, but with my slow internet speed, he says it's impossible.
I was suggested to use one of the paid services, but I'm concerned that if my slow connection will not work for the xda dev, why would it work for a paid unlock service? My connection is 5/1. Anyone have any luck buying the expensive @$$ service and successfully receiving the code with a slow connection?
Is there really no way around the T-Mobile Unlock App?
Is there truly no DIY process or program that I can do, being that the paid unlock services may not to work?
I really need this phone to work. I just moved to Costa Rica, and I use my phone to work. So, I am pretty damn stuck between a rock and a hard place with spikes. I'm pretty desperate, almost willingly to pay my last money to a dumb unlock service.
But some of the services say that it will not work if the phone is blacklisted.
I just don't know what my options are at this point.

Might be able to resell the phone with a *disclaimer* that it is blacklisted, I would recommend Swappa over Ebay though, (I got a really decent chunk of change for my Galaxy S Blaze that I sold on there), and then use the proceeds from that to acquire a phone that isn't stolen.
I got mine unlocked in a repair shop at gaffar market,delhi,india for rs 3200 inr and it was blacklisted on tmobile's website, when bought it was unlocked but after few days it automatically got locked to tmobile.
I mean to say if i can get it done in india you guys can also get it done in your countries.
You would have to do a firmware swap - which you could do yourself - you just won't be able to use it on that particular carrier, even via an MVNO on that carrier. My own S7 is ex-VZW (network locked); but I could take it to T-Mobile (and did) via firmware swap. My carrier (Tracfone) uses both VZW and T-Mobile towers ; while VZW was out, T-Mobile, however, works fine. If you sell the phone post-swap, include documentation that a firmware swap was done, so the buyer does not try to take it to T-M by mistake - some folks insist on following the labelling unless expressly told not to. (My S7 still has VZW labelling.)

Firmware swap? So you're saying you can take a Note 4 on T-Mobile that is blacklisted and you can fix the problem just by flashing a new firmware from AT&T? Am I understanding that correctly or no? Because I have a Note 4 that is on T-Mobile that someone left at my GF's work and never came back for, so they wanted to throw it away, so I took it, I rooted it, deleted all the bloatware and have it working great as a small tablet, but I can't use it as a phone because it is blacklisted. Been trying to find a way to use it for years now with no luck, I will not dish out any money to one of those sites, I don't trust them. If there is a way I can do it myself I would surely try it.
Indeed You Can

A blacklisted IMEI only affects the blacklisted carrier in question - it does not affect ALL carriers. (I cannot take my Snapdragon S7 to Verizon or that side of Tracfone due the IMEI being Verizon-blacklisted; however, it does not affect T-Mobile or the T-Mobile side of Tracfone - which is a separate network/carrier - which is why I was able to take the phone there.
. In your case, your Note 4 has a T-Mobile blacklisted IMEI; therefore, you can take it to AT&T Mobility, Verizon, the Verizon half of Tracfone, or Sprint - you simply need the apropos firmware and SIM. If the phone itself has T-Mobile labeling/branding, and you are trying to sell it, you should include documentation indicating what was done, and why (honesty). The biggest issue is sellers that DON'T do that (document what was done) or worse - don't do a firmware/ROM change for a phone with a blacklisted IMEI. So you can actually use it as a phone - you just can't take it to the original carrier.

This is what I am saying - that and a SIM from a carrier other than the one that blacklisted the IMEI - I took my own phone from VZW to T-Mobile (Tracfone supports both carrier networks). Because it was an internal swap (same MVNO), it cost me nothing.
