Wanting to know everyone's opinion, should i go back from unlocked firmware to t-mobile's firmware? It was originally my firmware until i flashed U1 firmware onto the phone. Still DL the firmware but wanting to get some opinions about it.

I have a u1 unbranded model using an att sim. If I understand correctly I can flash the att csc and get the wifi calling etc features?

If so, where do I get the att csc file?
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Download the at&t firmware either on sammobile.com or updato.com
[Samsung Galaxy S8 Guides, News, & Discussion] f10a:
Found the ATT firmware. Anyone have step by step instructions to flash the ATT CSC?
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Just extract the firmware, find the CSC file, open modified ODIN, place CSC file in its respective place, and flash it and you're good to go.
[Samsung Galaxy S8 Guides, News, & Discussion] f10a:
Thanks. Will this wipe the phone?
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Yeah so contain a backup of your data before doing so
[Samsung Galaxy S8 Guides, News, & Discussion] f10a:
Lastly, will this effect OTA updates going forward? Will the updates be ATT or XAA?
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
If you're on U1 firmware, you're definitely still get the XAA firmware updates. A CSC file is basically where you get certain features for a certain carrier, such as VoLTE and Wifi Calling.
[Samsung Galaxy S8 Guides, News, & Discussion] Thor2j:
You will not get wifi calling to work without providing att with an imei number from an att phone with this feature.
[Samsung Galaxy S8 Guides, News, & Discussion] jpcdeux:
1. No, just flashing the csc will not just enable wifi calling

2. No, just flashing the csc won't wipe it IF you flash the HOME csc.
[Samsung Galaxy S8 Guides, News, & Discussion] f10a:
So, now we have conflicting information.

What WILL enable wifi calling on ATT using the U1 XAA model?
[Samsung Galaxy S8 Guides, News, & Discussion] jpcdeux:
If you figure it out report back because I've tried every combo I could think of.

You can always just flash the full att fw.
[Samsung Galaxy S8 Guides, News, & Discussion] Thor2j:
Once again after flashing full att u must give att imei number from legit att phone with feature.
[Samsung Galaxy S8 Guides, News, & Discussion] coco1969:
Has anyone on Sprint been able to make hotspot wifi to stay on? I can get Bluetooth to work but WiFi hotspot is not staying on, disconnects after 2 seconds.

Any ideas?
[Samsung Galaxy S8 Guides, News, & Discussion] jpcdeux:
You give them the IMEI, they enable the data, etc so that the features of the rom will work. Doesn't need to be a "Legit AT&T phone" it needs to just be capable.
[Samsung Galaxy S8 Guides, News, & Discussion] Rally517:
Hello good peeps. I'm on boost mobile s8. And I was wondering if it's possible to flash Verizon firmware on it cause my service sucks where I'm at. And would I flash unlocked fireware first then Verizon? Or can I just flash firmware ? And how would I return can't seem to find boost firmware anywhere. Thanks
[Samsung Galaxy S8 Guides, News, & Discussion] Thor2j:
Not true, If it were factory unlocked s8 would work with its imei number and they don't. Must be a imei that att has in its database, thus an att phone with those features. Doesn't have to be active though.
[Samsung Galaxy S8 Guides, News, & Discussion] jpcdeux:
Sure. Just like using a Nexus device when data wouldn't work until you called them with the imei. Not an att phone but once they got the imei LTE and data started working. I know, this isn't a Nexus device but as long as the CAPABILITY is there it will work.

I'm sure my experiences over the years are wrong though.
[Samsung Galaxy S8 Guides, News, & Discussion] Thor2j:
LTE and data work fine on factory unlocked s8, no wifi calling. Imei from s8 unlocked doesn't work. Needs to be att phone with features so please update your years of experience.
[Samsung Galaxy S8 Guides, News, & Discussion] jpcdeux:
I'm sure with att FW and them having imei it won't work at all. No reason it wouldn't but I'm sure. You're absolutely right.
[Samsung Galaxy S8 Guides, News, & Discussion] Thor2j:
Many people have tried. If u give them imei number from unlocked s8 they will tell u it's not an att phone and thus u will not get wifi calling. I've personally talked to them and done this along with many others. You will be able to toggle wifi calling on and in about 3 seconds it will toggle back off.

Please stop giving misleading information and grow up.

Hey, I'm using cricket wireless(aio) with the unlocked firmware. I flashed the unlocked firmware then flashed the aio/att user data. I'm able to get all the cricket/att options(like volte) but now I'm not able to receive ota. I was under the assumption that if I flashed the att user data I would be able to get ota updates cuz I'm on the att user data. Is this not correct? And if not how would I go about getting ota if I can? Anytime I do the update system I get this(in the picture) and I know there are updates available after that. If i flash the latest csc for aio(cricket s8) will i get all the features from that csc?

Hello everyone out there*

I have galaxy s8 plus tmobile and I flashed to Canadian firmware now I would like to go back to T-Mobile in order to get the tmobile device unlock app work again*

can you please help me to get the T-Mobile stock ROM completely thank you all
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Since you're on U1 firmware, you're still going to be getting U1 updates, no matter what you do.
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Ok so If i apply the new csc for aio will i get the features? I don't care about updating yet.
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Either go on www.sammobile.com or www.updato.com to grab the t-mobile firmware of your galaxy S8+. Just type in your model number (which is SM-955U) and find T-Mobile and find the updated firmware, download it, and reflash it and wazam, you're completely stocked on T-Mobile firmware. But be advised, you will LOSE your data again, so back it up if possible.

Question for the experts .... My s8+ is sim unlocked via tmobile i went to metro and the hotspot wont work ..... Metro has the s8 but no s8+....what can i do to get hotspot working
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Hm im assuming you have their unlimited data plan on this one. It possibly may lay in the billing of your plan. If it's nothing with that either, just pull out the sim and re-put it in. I used my friend's metro sim card and my s8 couldn't retrieve any signal what so ever it was no signal the whole time. So it may lay into some sim settings not being properly changed to work with metro.
[Samsung Galaxy S8 Guides, News, & Discussion] tucsonjack:
Thanks will give that a try. And i am on the plan that includes hotspot.

[Samsung Galaxy S8 Guides, News, & Discussion] TimelessPWN:
No one has it rooted currently someone said the have the ENGBOOT but nothing since then
[Samsung Galaxy S8 Guides, News, & Discussion] Akumai:
I....kind of doubt the legitimacy O-O

If it really does exist and has been leaked, how come nobody else has found it? If somebody did find it, it should really be posted here asap
[Samsung Galaxy S8 Guides, News, & Discussion] TimelessPWN:
I agree I spend at least 2 to 3 hours a day browsing foir anything related to engineering bootloaders, engineering kernels, and userdebug firmware for this device and absolutely nothing. Unless he is the one leaking it from Samsung, then I doubt it as well but if he has something and posts it, and it isn't what he says a lot of devices could get messed up.... Would love him to send it to us so we can have a look at it first.
[Samsung Galaxy S8 Guides, News, & Discussion] sd_N:
Heres this...

The G950U Eng/DeBug version is there too. I couldnt for the life of me get a payment processed. I believe it's worth a look.

http://romup.com/search?version=G950USQU1AQCF

I just can't get my payment to go thru. Lol. However is someone can get it downloaded with proof, and post it here, I will gladly re-imburse whomever the $45 fee. Any ways....

edit: Also it was updated on 5-1-2017...which shows the time zone difference and there have been several more downloads as well.
[Samsung Galaxy S8 Guides, News, & Discussion] TimelessPWN:
As it stands I have emailed the poster of that firmware and he says he DOES NOT have the ENGBOOT, if someone wants to download this file for $45 dollars that is on you... I DO NOT advise it until I here more from the poster!
[Samsung Galaxy S8 Guides, News, & Discussion] sd_N:
Ok

I'll agree with you. It sure is enticing tho. Lol. IF, it's not what he says it is, it should be pulled. I wonder if they have moderators for that? Or maybe he's denying it because it IS a leak. Anyways, ... thanks for the advice. Hope we can figure something out soon. If anyone can point me in the right direction I'll be happy to join in the search.
[Samsung Galaxy S8 Guides, News, & Discussion] The bodhi:
Check the following models if you are interested

s8 sm-a520 sm-c9000 sm-w2017 sm-c7010

None of these models will flash eng boot

You get a binary error

Samsung seems to have added some validation that will recognize the eng file when it recognizes that you are flashing eng boot

It will stop you from starting
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
so you do not have any S8 ENG firmware.. thats all we were asking for lol

and just bcuz you got a binary error previously doesnt mean itd be the same.. we also have combination firm with factory binary BL and boot that potentially would allow us to flash an ENG boot with no issues
[Samsung Galaxy S8 Guides, News, & Discussion] TimelessPWN:
Those are not S8 model numbers??

[Samsung Galaxy S8 Guides, News, & Discussion] kevkid:
According to this:

https://firmware.gem-flash.com/index.php?a=browse&b=file-info&id=20861

Looks like it has an engboot?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
that is what we already have.. we have the combination firmware factory binary rom.. the included BL is not what we need as it is still locked..

an ENG boot would be good too asitd probably help us obtain root..

either that or a FULL debug firmwae

---------- Post added at 09:13 AM ---------- Previous post was at 09:12 AM ----------

no.. we already have the combination firmware lol in fact its posted in this thread a few times
[Samsung Galaxy S8 Guides, News, & Discussion] TimelessPWN:
I have this file it is the one posted in the OP, will download his and see if there is any difference's, but currently this firmware does not have engboot/binary
[Samsung Galaxy S8 Guides, News, & Discussion] barisgg:
I've flashed the binary in the OP it's definitely not the same, and I'm not near my usual set up so I couldn't do more to figure it out myself before I posted. Not to say that I really could.

I just spent a few bucks getting this just in case because people here have been talking about it, no reason to be salty. If it isn't it, which I figured it probably wouldn't be when buying it then whatever.
[Samsung Galaxy S8 Guides, News, & Discussion] TimelessPWN:
Wasn't being salty man, just from knowledge combination firmware does not contain what we need i am downloading your file now and will flash it when finished
[Samsung Galaxy S8 Guides, News, & Discussion] barisgg:

Hi

Thanks for your thread i[m trying to change on a t-mobile s8 and i can´t do it. Your file says isn´t a md5 valid and with the files i downloaded on sammobile i get an error on the phone after that on odin is succeed. any idea?

Just got our T-Mobile S8's unlocked after paying them off with rebate card. Our service is terrible though so we were thinking of going back to AT&T or VZW, doesn't matter. I am OK to flash this unlocked firmware to the phones and have them work with either carrier? I will continue reading back to see if I can find the answer, but much appreciate if someone can chime in. Any issues using unlocked firmware on either AT&T or VZW (features missing)?

The T-Mobile phones are currently on G955USQU1AQGA build, still able to "downgrade" to the unlocked firmware?
[Samsung Galaxy S8 Guides, News, & Discussion] castuis:
If they're now unlocked all you have to do to get it working on AT&T or VZW is insert new sim. Tmobile unlocked and factory unlocked flash are going yo be the same minus the carrier bloat and splash screen. I would either leave it as it is now, or wait until you pick a carrier then flash that specific carriers rom if there's features missing after sim swapping

Maybe I should foo process without my son card in? Judy looking for your in site. Thanks for all your help:svetius:
[Samsung Galaxy S8 Guides, News, & Discussion] billa:
Seems that a lot of people confuse flashing the so called S8 "unlocked firmware" (which is technically "unbranded") with network unlocking.

Simply flashing the unbranded U1 firmware will NOT unlock your network, unless you have done so before or after flashing by either unlocking codes or apps.

All it does, is to give you an unbranded bloat free experience, AND it configures the phone with the inserted sim carrier's special features (well, mostly).

Hope that helps to clear up the haze.

Oh by the way, the $150 remote unlocking service will change your esn/imei, which resets the security area, and as a side-affect it also network unlocks the phone (kind of a grey area with stolen certs database, etc.)
