[UNLOCKED] SM-G935T / T-Mobile

[purotijuana]

Hi community,
A question for many of us in regards to 'unlocking' or "how to unlock" from our carriers, I have done a very simple and silly way to unlock my phone from T-Mobile.

I am currently under SM-G935U Firmware (4API3), coming from SM-G935T's 4APIA Firmware.

Follow these simple steps in order to unlock from your carrier.

***NOTE: THIS METHOD ONLY WORKS IN STOCK FIRMWARES. YOUR DEVICE WILL BREAK IF YOU TRY TO INSTALL UNDER A CUSTOM ROM***

1.- If you have previously installed a custom ROM (Echoe, Tekv2), say bye bye for now. Using Odin latest version (3.12.3), flash Stock Firmware '4APIA'. After set up enable developer options and USB Debugging.
2.- Download SM-G935U's official firmware from SamMobile or Samsung-Firmwares (Make sure you download the TMO region firmware)
3.- Create a new folder on your desktop, copy and paste BL & AP files from the SM-G935U firmware you just downloaded. From the SM-G935T stock firmware you downloaded, copy and paste CP & CSC_HOME files.
*Basically you will have BL/AP from G935U and CP/CSC_HOME from G935T*

4.- Flash these files through ODIN, but WARNING: After flashing your phone will reboot. Go into recovery mode and wipe cache/data + wipe data.

5,- You will get to see a dm-verityverification failed, no mount blah blah blah. Just ignore it. After deleting cache and data reboot again into download mode...BUT THIS TIME ONLY FLASH CP file from G935T while the CSC_HOME you will flash now will be the official G935U file.

6.- After reboot, done.

I was able to install Google Voice

Sounds promising going to try this when I get home, was having all those issues with dm-verity.

Have you tried just wiping the cache and not wiping data with success? (Dirty flashing)

Or we all starting from scratch?

since root with eng kernel makes my phone burn up and kills my battery, even with all the remedies. The g935u is an option I would love to play with.

But how did you unlock the sim? You have the unlocked versions firmware so less bloat and no carrier garbage but the phone itself would appear to still be locked to TMO. Splain.

Hi there. This firmware is so much better than the stock TMO firmware, everything works excellent. I used stock tmo firmware first APIA, next tmo G935U API3 next. I tried your way first on a S7 Edge with bad IMEI and it wasn't working. I used another S7 Edge but this time I flash all the G935U API3 firmware, it work flawlessly with one simple try. Just put AP/BL/CP/CSC and flash with the latest Odin, you wouldn't have problems. My 2 other TMO S7 Edge are on stock G935U and saying official.

Yes indeed it is. G935U feels great, faster response, no lag at all and for some reason I get 4G LTE even with Roaming (Mexico) I am still with T-Mobile...were you able to UNLOCK the SIM?

Hey bori,
Every time I flash a custom ROM or even going back to stock, I always wipe cache/data. It is just the way I like to do things on my phone, not keeping any traces from previous ROM/FIRMWARE.

Make sure you download the official Firmware from SamMobile or Samsung-Firmware.

I heard updato is a fast download Firmware site.

Well i tried last night but ended up with the same results. Goes perfect in Odin. But boots straight into recovery even though I wiped everything and reflashed cp and home csc from g935t files.

For the TMO and other SM-G935 firmware, check out THEANDROIDSOUL.COM . They have about 90% of all firmware.

I'm not a big fan of stock roms, custom is the way but this TMO G935U FIRMWARE IS THE ****TTT !!!.
The last time I used a stock Rom was from HTC EVO 4G, after that was the Sprint S2 and I never USED ANY PHONES WITHOUT A CUSTOM ROM TILL NOW.
This TMO G935U FIRMWARE, I did a ANTUTU BENCHMARK LAST NIGHT after flashing the firmware. Mennn! The score was higher than the note 7 N9300 by 4000 points, I couldn't believe it. I did a second test samething. The battery performance is excellent.

All mine said was applied multi csc now I get lte+

Nah I didn't try to unlock it yet, I have to get an AT&T sim card or simple mobile card and see if it ask for codes. If that works that will be great for everyone ?.

 

[crashnova]

Which U firmware are you guys flashing and what would be the differences between them? I'm currently on the T-Mobile U firmware.

 

[sajwhat]

tried this... asks code also ... but anycode can give message "network successfull".
BUT its not unlocked... still "invalid sim card inserted error" is there.

 

[bryanpen]

So this method works or not? I want to know before I take the plunge. Also Dm verity error doesn't sound good either. I had a note edge with that error and it was a major headache.

Hi all. As far as I can see, the U firmware unlocked the phone. I inserted a SIMPLE MOBILE CARD into my G935T running G935U firmware, the phone boot into like recovery mod but the screen go BLUE and it configures SIM UNLOCKED SYSTEM, then it reboot and walla the phone have service on SIMPLE MOBILE NETWORK. I was very SURPRISED it works because the phone is locked to T-Mobile and only the DEVICE APP to unlock it. So at this point I'm only using the G935U firmware on my G935T, no more T-Mobile firmware bull crap. Next I'll get an AT&T SIM card and try that for 30 days.

What steps did you take to get this to work?

No matter what I do I cannot get my phone to go into the Samsung sim unlock screen after flashing in various combinations, including following the OP exactly

I know this is a late response but it's good to know. SimpleMobile has been running under T-Mobile Network, whether your T-Mobile Phone is locked or unlocked it will work when a SimpleMobile Sim is inserted.
