Didn't work? A little more details and maybe we can help you. I have went from apk1 to qa6, took the latest ota from qa6, had issues with mms so i downgraded all the way back to apk1. What files are you using to downgrade. What version are you trying to go back to. You can only go back so far (i think apk1) since your bootloader was updated along the way somewhere.

You have installed a custom rom and you want to go back to stock rom. Okay
Find your stock rom here (re-check your version of s5)
http://www.sammobile.com/firmwares/database/SM-G900F/
Install twrp for s5 via app (if rooted) or via odin.
google it for links.

You stuck at bootloader bootloop? Well, you need to update your bootloader. That will fix it.
There might be an update for marshmallow for Italian s5. Wait for some time.

You don't need to flash it via odin. You can do it through OTA (on the air.) You will get a notification when you have the update available.

If you want official marshmallow touch wiz, then you need to flash stock rom and then update it to marshmallow through OTA. That is what I meant.

Flash T-Mobile S7 ROM on AT&T S7

Hey XDA,
I just recently purchased a AT&T S7 (SM-G930A). I also just recently found out that AT&T doesn't push updates to non AT&T network phones. I am using the phone with T-Mobile and I was wondering if it was possible to flash the T-Mobile stock rom without tripping Knox or anything of that sort. I remember being able to do this to my AT&T Note 2 back in the day. If it is possible, can someone kindly link me to the file and instructions on how to flash the stock ROM from T-Mobile? Thanks!
You can, however once you do you can't go back. It may be possible in the future, but Tmobile has a v3 bootloader, and AT&T is still on v2 bootloader.

Thank you! One more question, I have the stock T-Mobile ROM and for the CSC, there are two files:
CSC and HOME_CSC
Which one do I choose in Odin for the CSC option?
Thanks
When attempting to flash using Odin 3.12.3, I get this error in the log:
FAIL! SHA256 is invalid
This seems to be because of a corrupt file?
I downloaded the ROM from two different sources now and still I get the same error.
Thanks

So TMobile ROM on 930A . Any issues ? Did you try going back to AT&T ROM
All that talk out bootloader versions and not able to restore back to AT&T ROM
Can you odin Unlocked 930U version ?
I'm using Cricket on AT&T S7 variant and I couldn't get any update from AT&T, which pissed me off. So I decided to flash G930U firmware and I succeeded. But unfortunately, there isn't a single G930U update been released so far, which is quite surprising.
Other than the update, I'm extremely satisfied with the new firmware. It's so fast and clean comparing to my previous bloated AT&T firmware, free of all kinds of overheating, battery dropping, slowing down, crashing, auto-restarting, bugs and lags (Just so you know, my G930A firmware was the newest. I had to take my phone to Best Buy to update. And I used PDP to disable bloatwares). I highly recommend everyone to flash G930U. The new firmware also has an APP called Samsung+. It's very useful and it tells you if it detected slow charging, or reminds you to restart your phone if it hasn't been restarted for a while, etc.
I'm still wondering if I can receive OTA after flashing anther variant firmware, but I can't confirm since there's no update for G930U yet. I'm curious to know if OP could receive any T-Mobile update after flashing.

No issues at all so far. Works perfectly. I don't really want to go back to the stock ATT ROM because I don't need it.

I flashed to the latest update of the ROM so I can't prove it works. But from what I've heard, after flashing the ROM you need to factory reset the phone so it can unregister from att and register to whatever carrier you are using it on. I am not sure how true this is but I read it somewhere and it seems to make sense.

if you ever switch ROMs please check about the issue of bootloader version and not able to revert back .
Not able to revert back is the only issue keeping me from odin to T mobile ROM
If bootloader version is a problem then you cannot flash 930U firmware also
Is that so ?

I'm not sure what bootloader the G930U has. The att ROM has v2. If it's newer than that, then downgrading isn't possible. Is its the same, then it should be fine.

I was also able to flash the 930T on my 930A. I saw there was a Note 7 port but you need root and TWRP. Haven't tried flashing back to 930U yet, but thinking about it.

06/03/2017 new security patch update arrived in 60mb (N910TUVS2EQB1)

I just received security patch update in 60mb.
Everything running very smooth so far no issues.
"Edit" users who are curious to know that bootloader is still unlocked and i downgraded to epe3 and dok2 just fine.
Just received same update. Working great.

I'm a relative noob to flashing rom's. Can someone tell me if I'm understanding this correctly?
Installing this update will *unroot* my phone? So after installing this update through odin, I will need to install twrp again while in download mode? And then, once that's installed, reroot my phone?

My dad got a Tmobile Note 8 Used on Swappa, and it came with the Beta. I'd be all over that, but its got some usability issues like the camera won't zoom and other random glitches, so its not good for him. So I'm on the hunt for the Firmware ODIN files to revert.

Awesome I shall Check out what he's on. I'm not sure the specific details of the versus but I know it's Oreo and the Easter egg animation you get from tapping on the android version number gives you an octopus :laugh:
I'd love Oreo on mine, but I'm stuck with Xfinity Mobile don't see them doing an oreo update any time soon, Grr @ offshoot carriers.

Hi! Can 950U1 firmware be flash to 950U firmware on tmobile purchased phone. My note 8 in now carrier unlocked by t mobile. I'm trying to get rid of the t mobile bloat. I'm no longer on t mobile plan.

Can I install this ROM?

So I found this on the XDA home page. It says SM-935A is required (I have SM-935U) BUT I thought that model number mostly applies to which carrier you're using...So if I flash the lates AT&T version via Odin can I then update to this Oreo build? Here's the article:

Thanks. I might hold off till there's a more stable build. If I didn't need to wipe everything I might give it a try.
But in case I change my mind, you extract the update.zip and apply update from sdcard, right?
