Hi there!

How do you flash your SM-G930A with oreo?

I'm trying to do with 2 Odin versions and the firmware I got on firmwarex.net and it won't work at all!
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] lumiden:
I don't even remember, but there is a fixed version of Odin for these models. And the firmware from sammobile.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] Neoguto:
I do it, finally, but i'm trying to flash this convertion firmware to unlock the sim card, with no succes.

I try a lot of versions of Odin, and always fail the instalation, have any idea how i'll do that?

I'm now with a rooted official 930A oreo firmware (SuperSu, original bootloader)!
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] dannyboy833:
I flashed the SM-G930U on my SM-G930T. But before that I had 4G LTE in my room. After flashing the U firmware, the phone never gets a signal (Emergency Calls Only). Outdoors, I have strong reception.

Tried reverting to T-mobile's firmware but it also fails to get reception in my room.

Hi guys, i really need your help here. I tried to flash my verizon g930v with g930u using OPs directions, and now i'm stuck in a bootloop and recovery is dead. Ive tried different odins and tried going back to the stock firmware, with no luck. I need this fixed asap please, we need my phone for everything. TIA.

SW REV CHECK FAIL: [aboot] Fused B> Binary 4

I think it depends on the fact that your rom is version 4 while I on galaxy sm.g930a I am already at version 8 (bootloader)

Is it possible to do something? with the original AT&T firmware I have problems with the telephone signal
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] WangGang:
So I flashed the firmware successfully and got to the setup screen, and I had to deal with FRP. I did as it asked and entered the previously synced email. However, upon doing so it asks me to enter it again in a never ending cycle. What do I do?

No connection to mobile network (Emergency Calls Only)

Hi all,

I have succesfully used this guide back in 2017 to flash my unlocked 930a (ATT) bought over Ebay from HK to 930u and everything was ok for about a year, phone has been receiving OTA updates, no other issues. This lasted until around August 2018 when a) we were out of UK on holidays in Europe and b) used local SIM there (worked fine) then c) a OTA update pushed in - think it must have been first Oreo update 4CRG2.

Since then, the phone would not connect to mobile network ever. The local SIM we used first days fine wen to "Emergency Calls Only", used my main UK one with the same result. Tried all things like manually selecting network, disable/enable flight mode, disable data.. no joy.

The phone however still worked fine on Wifi effectively becoming small tablet.

There was no time for me t mess with it on holidays so ended up getting new SM-G9935 and put this one to shelf. Yet it is still perfectly good phone, kids started to use it again an I would like to be able to get working on mobile network.

Symptoms:

- There is no message complaining about SIM lock, phone lock or anything signalling an error

- Phone shows signal strength, using Signal Info it gets local mast details.

- Strange thing is, that I do have 3 country SIMs now, all working fine in other phones - but even when foreign SIM is inserted, the SIM status shows OK status, SIM provider recognised, yet Roaming is always OFF. I'm not sure if it is phone itself determining its roaming status or it is required to connect to any network). yet my phone see it in on UK network, it see there is another Euro SIM, or US T-mobile SIM... but remains constantly on "Roaming OFF".

I was looking up internet to see if anyone experienced similar issue, notably related to update, but found nothing.

Since phone has working WiFi, it has been gradually installing all updates so currently on ACSF1 (XAA). Given the Bootloader verision is A (10), I can not really downgrade back to Nougat version that I know was the last working. Tried to flash it back to 930a works, yet even then the phone won't get on the network.

Tried to flash it with various other 930u firmwares to no avail. The phone remains constantly in "Emergency calls only" and claims to have roaming OFF despite inserted SIMs should definitely be recognised as other country carrier's, i.e. in roaming. These were full "clean" flashes mostly, when tried with HOME_CSC ones, Cache Wipe and Delete Data has been performed... so there should not be anything left behind from previous software.

So I'm basically looking fro any suggestions from the experts here about what else to try to get this phone back on the network .:confused::crying:

PS. run the IMEI check and it does not show phone on any blacklist
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] Enjama:
Can anyone check G930U has multi language ?

Now i have model from Att G930a and here are only a few language.

Im looking for Polish (Polski) language, can anyone with this firmware G930u check ?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] roge50:
The new firmware was the solution.

Thank you, the new firmware worked for me. I've been trying for a few days with the original OREO and had all kinds of errors.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] itstanner740:
Does this still work for the SM-G930A updated to the latest android version, security patch, everything updated to date? I recently tried another one on here and bricked my phone. Luckily I found stock firmware that fixed it but I'm too scared to even try again because I'm so ignorant to this stuff, I need help!!

galaxy s7 couldnt convert from g930az to g930u

didnt work for me. got stuck in a bootloop into recovery. :(

---------- Post added at 12:18 PM ---------- Previous post was at 11:43 AM ----------

How did you get this to work? I downloaded the firmware from the link on the first page named SM-G930U_1_20180705153340_sf441dvtz6_fac-001.zip. It fails on my g930az cricket phone, causing a bootloop into recovery. the only way to get out of it is to flash the stock rom back if you can get into download mode that is. it takes many tries to get from the bootloop into download mode. I currently have g930aztus9csb1 and the phone is frp locked.

Any help to frp unlock and flash to g930u version would be amazing.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] SteveKane:
First of all, thanks for this thread to OP and others!

As to problems with Odin download on Oreo, I only managed successfully with Odin3 v3.13.1_3B_PatcheD.

Hope that might help prevent some frustration for those that had fails with other versions.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] SteveKane:
Try Odin3 v3.13.1_3B_PatcheD , it worked for me.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] C_King_Of_Languages:
Hey guys, I was going to follow the process in this thread https://xdaforums.com/t/easy_root-u..._bootloaders-tmp_twrp_recovery.3859757/page-2 but apparently it says you must have a v4 bootloader.

Will this updated firmware work with modern patched Odin for my SM-G930U UESBCTA3? Which i presume has bootloader version 3 based on the 3 in the baseband number, and which I also assume has a locked bootloader due to being in the US?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] aviseqdas:

Can this be flashed on the AT&T Stock QE1?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] DavyCrockett:
Thank you Matt.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drpudding:
so whats the HOME_CSC and CSC are those the same or you flash a specific one

sorry new to s7 flashing it was never this complicated before on other samsung phones. i have the g930a model and i want to move over to the U firmware for OTA updates. also will tmo wifi calling work on U or not yet?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] loganbeck14:
I'm going to clear some things up real quick. You don't need to be unlocked and unless you got your phone unlocked by a third party unlocker flashing will not re lock your phone and YOU DONT NEED TO BE ROOTED this guide is to help you get rid of bloatware and have the newest Android nougat without rooting
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FrostByte X:
I am also wondering about this. I just went ahead flashed the regular CSC. I will report back if anything weird happens.

Edit: No problems occurred.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] mattgrantlackey:
I just picked one, not even sure which. I have had zero issues with installing this on my 930a. My battery life has easily been doubled, the phone is much faster, no bloat, all the nougat goodies, and i can tether now. Whats not to love? This is how the phone should have come factory.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FrostByte X:
Yes, I totally. The phone is so so much more fluid and more enjoyable to use. My AT&T ROM had so many graphical glitches and I am happy that it's gone.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drpudding:
Yea I agree. I didn't notice since I'm not a day to day Samsung user but my sister noticed the blazing speeds and was like "how?!" So I assume the bloat is real
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] chudm:
guys one question, can i use this on a 930v? (the phone wont use a verizon sim card)
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] SkyAttacksX:
Hope I'm not late. Haven't visited this forum in a while, but IIRC "Home_csc" keeps your data as if you were updating your phone via OTA. Non-home wipes.

Hope this helps. ;)
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] chudm:
So it should be fine to flash this over 930v, but i shouldnt flash home.csc right?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] SkyAttacksX:
Correct. Otherwise you'll still have the bloat and not sure how it will interfere with booting. Personally, I think it would be useful for unrooting on the same ROM without wiping, but I haven't tried that although I am rooted.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] thegreatkazoo:
Does this keep sim unlock? That's the only reason I haven't flashed a new firmware.

I didn't go thru att to do the unlock but I used the code and didn't try to go around anything or get it for free with some adb shinanigans.

Any insight?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] chudm:
I only have 1 doubt about this, the vz edition is unlocked for gsm bands, and im using this phone outside of USA, i wont have any problems with others simcards if i update it without home.csc right?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FSRBIKER:
Not that I use it often but would Video calling from AT&T not work anymore? I'm assuming it's built into their software build.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drpudding:
Thanks for this [emoji4]
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] loganbeck14:
You will lose wifi calling, hd voice and you will lose video calling as well
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] SkyAttacksX:
Not sure. If it's unlocked, then theoretically with "unlocking" having to do with unrestricted access for the IMEI (i.e. allowed on any network) it shouldn't be affected. I can't say for sure, but I would think firmware doesn't affect it. Have you factory reset since then? I would weigh your options and be prepared for "if" something goes wrong. Like I said, nothing should go wrong, but there's always a possibility, so be prepared. That's my insight. :p

Given that this is the U firmware, if it already works outside the USA then it should continue to do so. If it doesn't, just re-flash the stock firmware. No big deal there. :p

Nope, it won't work. I'm on AT&T and it doesn't add that option, so it would be software related. However, I would think that if you root and had the app package for the dialer, it would likely work if you know how to get it installed. There's also a separate package for video calling if I'm not mistaken. But other than that, it's gone. Hey, you get a feature that identifies (spam) callers though! I personally like that, but I digress. :)

No problem. :)
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] thegreatkazoo:
It was unlocked thru a company. Had to pay to get an unlock code so it wasn't anything like flashing or whatnot. It says it's guaranteed to work regardless even after the fact.

I have not factory reset the phone since I got it unlocked.

[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drpudding:
I had all U firmware bits and it unlocked fine for me on my G930A. Even had the U radio installed and it got the wifi calling setup for me. I think it was only VoLTE that wasn't working but that was it. I just flashed this update and waiting for the new update to rolling thru on OTA
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] thegreatkazoo:
Might end up doing this tonight then.

Sort of see where I get.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drpudding:
Yea I'm still not seeing the VoLTE option in the dialer settings. So not sure what I'm doing wrong right now.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] thegreatkazoo:
Probably nothing.

Did you unlock after the flash to U?
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drpudding:
Yea. After I flashed U.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] thegreatkazoo:
Wonder if that will make a difference with the unlock.

Mine is already unlocked but I'm not wanting to relock it with a flash. That would suck. Lol.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drpudding:
If you unlocked the normal way with the pin code (official unlock) that att or a website like blowfish then it'll stay permanently unlocked.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] thegreatkazoo:
I did. Used a pin code from a site. Said permanently unlocked with some sort of guarantee.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drpudding:
Yea you should be fine. I've already flashed twice and it didn't relock
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] thegreatkazoo:
Guess I'll hook my hotspot up and get to downloading. lol

Edit: I'm assuming all the files are labeled? I haven't had to use Odin in quite some time.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] drpudding:
I flashed this. Everything seems to be working fine. Wifi calling and VoLTE as well. Using T-Mobile

Ongoing re-boot after installing

I have updated my AT&T S7 (not rooted, no simlock) as per the first posts in this article. Including a full factory reset. Everything worked great, downloading, installing etc. So for a rookie - I was quite happy that it all worked!

However unfortunately my device now continues to re-boot itself very soon after it has started. There is no way to get out of it. If there are any thoughts as to why this is happening, and how to fix, I would be very grateful for your help.

*edit: fixed. I used the home_csc the first time. Just followed the process once again but with the other csc. That did the trick.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] thegreatkazoo:
got my flashed a little while ago.

now have bluetooth tethering.

sim unlock is still valid

had to do some weird stuff to download previous purchases but thats fixed too

if i flash this latest firmware, i got the latest firmware U PDA G930UUEU4BQF3 and CSC G930UOYM4BQF3 from sammobile

is my volte and wifi calling work? and i can update with OTA update for future version?

samsung pay and secure folder can work too?

I just updated to qf3 on mine.

I have LTE+ and wifi calling. Volte I haven't tried mainly because I haven't looked for it.

I was on the qc1 when I flashed the firmware and did the 2 updates ota today and that bumped me up to qf3.

Everything works from what I can tell but I just did it a few minutes ago.

Model Number: SAMSUNG-SM-G930A

[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FSRBIKER:
I flashed all files Except Home_CSC on my 930A. That gave me a clean wipe of the device and it's been running so much better since I installed the U version. Just received the July security update the other day.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] tailgunner9:

[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FSRBIKER:
Still on AT&T but haven't looked for anything to turn on for either WiFi calling or VOLTE. Don't remember if I did when I was running the A version of the software either. If there is an area to turn these on in settings let me know and I'll look for it. Only thing I knew that won't work is Video Calls as that's through an AT&T app. I can just use Hangouts though.

So I Flash All files except the CSC, Correct over my QF3 Nougat I have Now? Do I need to Wipe Cache or anything before I Flash U version? Thanks guys.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FSRBIKER:
Follow the instructions in the first post, I did not wipe anything before flashing the U files. You need to also flash the CSC file, just not the Home_CSC file. From what others have said in this thread the Home_CSC would keep your setup without wiping it, not sure why you would want to do that when the real purpose is to get rid of all the bloat and files associated with it.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] tailgunner9:
Works Great after the Flash, But have No HD Voice setting to turn on as I did with G930A firmware. So No video calling can be done. Seems ATT would allow that since they sell SM-G930U phones with this firmware.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] FSRBIKER:
AT&T doesn't sell the U version of this phone. My guess is you might be able to get a rooted AT&T S7 user to pull the Video Call apk and try installing it.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] tailgunner9:
Thanks for reply. Guess just Best Buy and Samsung sell 930U phones then. Thanks again for you Help.
[AT&T Samsung Galaxy S7 Guides, News, & Discussion] tailgunner9:
No Video Calling or Enhanced Voice Now with U Firmware as I had with AT&T firmware. This is the Bad part of the U Firmware on 930A phone.
