Someone answered after I posted that about video calling. I just use Hangouts for the rare video calls now. Enhanced voice, not sure I noticed that but have no issues with calls. Those trade offs are well worth a phone that is much more responsive and has better battery life. When the Pixel 2 comes out I'll be handing my S7 down to my son.

[AT&T Samsung Galaxy S7 Guides, News, & Discussion] TaTaTaing:
I can't speak for getting updates if you are living outside of the US, but I would imagine you can.

Any SIM card should work in this as long as your phone is UNLOCKED. Flashing this firmware doesn't mean it'll unlock your phone.

For step by step procedures, go back to the very first post in this thread.

Verizon Sim will not work, have tried one.

---------- Post added at 09:24 AM ---------- Previous post was at 09:15 AM ----------

I installed this U firmware on my 930A over a month ago and its doing OK on AT&T. Version after Updates is G930UUES4BQG1 On July 1 Baseband version. Waiting on August update maybe next week.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] TaTaTaing:
Verizon didn't work? Was yours unlocked? That's strange, because I had just sold this phone a few weeks ago. There was one buyer who asked if Verizon would work, and sure enough it did when I put in an active Verizon SIM to test it out. Placed phones calls and used the internet with no issues while Verizon SIM was in it.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] tailgunner9:
Well I did not try a registered Verizon Sim that was active. I tried an unregistered one in my AT&T S7 and it would not recognize it. my AT&T S7 is Unlocked and it would recognize a T-Mobile Sim. SO do not know what to say then.

I think i need a little help here!

I have an unlocked at&t s7 930a, and i did all the procedures decribed on the first page. now im stuck in a bootloop where im am stopped by a message saying that an unauthorized attempt has been made to factory reset my device. I try to continue but the phone reboots. help me please!

Edit: after some googling i think it is the FRP lock : ON that's causing this. I am going to try and remove it

Edit no.2: somehow i got to fix it. I didnt mess with FRP. after several attempts to get it to run and recognize me as the owner, i decided to flash it again with odin. the process went good at the beginning up until the phone shower an error with the sick android figure(here i thought i bricked it). i restarted and the phone was doing some "under the hood reparations" with a sim figure showing on a blue screen. Amazingly, after that the phone restarted and didnt go into a bootloop again. ever since its been gathering OTA updates and working fine.

I have a G930A on cricket. Would like to lose the bloat but definitely want to keep VoLTE for HD voice. So far sounds like I'll lose HD voice if I flash the unlocked firmware, which doesn't quite make sense to me, because I'm coming from an unlocked S8 which I flashed to AT&T but still couldn't get HD voice.

Anyone know what determine whether you get HD voice on AT&T/Cricket? Is it the firmware, IMEI, or both?

Hey guys.

Forgive my noobie questions.

I have An unlocked At&t S7 in morocco using it with my maroc telecom Sim card.

My phone is running marshmallow 6.0.1

And can't update it through OTA to nougat because It is unlocked and i have no AT&T sim card or network coverage here either to try and gett an aT&T SIM for that matter.

But i want to flash this firmware in order to get OTAs and get rid of the useless bloatwares of aT&T.

I have two questions since my phone is now unlocked and bought it second hand i have no idea how the unlock process was , whether it was a factory unlocked or only carrier onlocked one.

In my case, Will flashing this relock my phone again ?

Will this make phone get OTAS in the future?

And how about that Home_CSC ? Should i use it to keep my phone unlocked or i should use my own country Csc which is Mat?

Waiting your help guys to start the process.

AS I'M STuck in 6.0.1 here and wifi hotspot isn't functioning.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] twizt3d:
I'm not sure how to tell what type of unlock you would have, and it may be possible that flashing with odin would relock it. I would recommend the u fw if you want bloat free stock. Otherwise you can run the a, but you will not get otas ever without an att sim and service.

Someone smarter than I may be able to say what would happen to your unlock if you sideloaded the otas however. It's an idea but if not sure how it would work.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] ZaKaRia OuH:
I'm confused by the idea of getting it relocked again.

But I will just try it out for the sake of getting OTAS in future.

I Just wonder if i will get OTAs as I live in morocco and I will be using U firmware.

So please tell me Should I flash Home_CSC ? OR i should flash my country CSC ? And what is its benifit ?

Thank you for your fiendly reply buddy.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] ZaKaRia OuH:
hey buddy.

what does this mean ?

does it mean if I choose another CSC like XAA one, will my phone lock again since i'm from morocco and i have my AT&T s7 unlocled?

I'm really confused by this.

can anyone friendly please clarify this for me.

In response to

"This can be done on all s7 variants except for the international and Sprint variants..."

I have flashed the unbranded XAA firmware perfectly fine to a Sprint variant using the modded Odin (both G930P and G935P)

Of course it doesn't unlock the sim/network, just makes it bloat free.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] Rev10eight:
Thank you so much for this. This worked perfectly in my G930A.

I had previously rooted this phone and returned it back to stock unrooted. I always had a problem with it afterwords, my fingerprint scanner would never unlock my phone. After installing this, my fingerprint unlock works now.

Hot spot works, bloat free, fast and stable. What else could I ask for?

Stock AT&T with freshly fully reset phone, Developer settings adb enabled and unlock checked, on 6.0.1. I just un FRP'd this phone today. Got it yesterday from police auction.

When it starts up stock it sets up just fine.

When booting into download mode with the phone unplugged, at the top left I get:

(red letters) ODIN MODE (HIGH SPEED)

PRODUCT NAME: SM-G935A

SYSTEM STATUS: OFFICIAL

FAP LOCK: OFF

WARRANTY VOID: 0X0

QUALCOMM SECUREBOOT: ENABLE

APP SWREV: B4(2,1,1,1,1) K1 S3

SECURE DOWNLOAD: ENABLE

So I unzipped the Universal file into the 4 .md5 files. Tried using those with the PrinceComsey Oden, 3.12. Error message FAIL... Re-partition operation failed.

Renamed the .md5 packages, removing the md.5, leaving them as .tar. Same result. I used the stock U CSC file. There is no Home CSC file. Fine by me.

I've gone into fastboot and cleared/reset the entire system, and started all over going into the phone and setting it up, Dev options, etc.... same results, over and over.

There was no PIT file in the package. My next step, as I understand FAP lock: Enable, means that is stopping the flash over the stock rom, and I read a suggestion somewhere to re-flash the phone with a fully stock rom.

New: So, now have flashed the stock AT&T G935AUCU4BQA6, and the flash worked. Reset Dev options, OEM unlock, adb, etc. It is on 7.0.

Rebooted to System, Reset Dev options, OEM unlock, adb, etc. and back to download mode to install Universal files.

Loaded 4 files for Universal package, and error'ed out again. On phone it said Secure Check Fail: PIT. In PrinceComsey Oden, 3.12. Final result: Complete (Write) operation failed. ...(succeed 0/failed 1). Re-try and on phone Secure Check Fail: aboot

Loaded the Stock OEM PIT file, and the process would not do anything.

It seems a number of folks have had success installing the Universal setup on the AT&T phone. I am stumped. Would someone please tell me how to solve this?

No more Voice over LTE?

Question -

1. In moving from the G930A to G930U, will I be able to have Voice of LTE (VoLTE) on AT&T?

2. Once I move to the G930U rom, can I then use the phone on any US network (like the real G930U) such as Verizon/Sprint/T-Mobile? (Assuming the phone is Unlocked)?

Meaning is this merely a ROM flash or does the phone actually convert to a real G930U phone?

So do you want to flash the firmware, allow it to boot without going into recovery, then shut it down from the welcome screen, boot into recover, and prefer a cashe wipe and factory reset, and it should be good? I'm mostly confused about what to do directly after flashing. Do you boot into recovery right after you flash and factory reset from there, or right after you flash, let it boot, THEN wipe cashe and factory reset?
