Downgrade firmware question. - AT&T Samsung Galaxy S7 Edge Guides, News, & Discus

I have a ATT s7 edge. I was running on g935AATT4CRE4. Oreo. I found a firmware that was a 935U firmware. I flashed it with Odin with no problems. I liked it a lot. I wanted to go back and compare the 2. I know, kind of dumb. I had issues flashing original firmware listed above. I did some research, I downloaded latest att software and flashed it. Worked fine. Here is Build number G935AUCS8CRK1 . Now I cannot go back and flash the 935u firmware. I have noticed the 5th digit from the end is now 8 and not 4. Could this be issue? Any ideas.

G935UOYM4BQD2 this is unlocked firmware

You are correct. There is an 8 version on the U firmware that will work though

Any idea where I can find the u version?

Found it on Sam mobile. Thanks

Is there a place to download this firmware without paying?

I found version 8 935u firmware. Used odin correctly. It flashed and said passed in green. Kept rebooting to samsung power on screen. What am I doing wrong?

You need to download and flash the SM-935U 8.0 firmware that matches your baseband version exactly if you scroll down you will see an USA(AT&T) version that matches your baseband that is the one you need.

So just to clarify. My baseband is G935AUCS8CRJ2 can I flash this Unlocked firmware? G935UUEU8CRJ2
If so, do I use all of the parts in Odin, or just AP?

Stock t713 firmware fail with Odin, pics attach

Failed to flash stock (XAR) firmware on U.S model
Using Odin. But can flash U.K (BTU) firmware. Why is it failing to flash U.S firmware?
Downloaded from official sammobile site and from
XDA link. Have pics attached.
Can anyone please advice?
Thank you.
It states;
FAIL! (Auth)
why is the authentication failing?
I also stupidly did not do a twrp backup of the original firmware.
Thanks in advance.

It says you are trying to downgrade your firmware. You have revision 2, you're trying to flash revision 1 firmware.
I guess you're flashing the UK revision 2 firmware T713XXU2APJ1?

Do you mean an older firmware can't be flashed?
This is the older failing firmware:
T713XXU1APG1_T713XAR1APG2_HOME.tar.md5
This is the one that works:
T713XXU2APJ1_T713OXA2APJ1_HOME.tar.md5
Or do mean a different model?
What can I do to fix this?
Thanks for your help.
Yes its UK firmware. I got greedy and didn't wait for the XAR version. So do I wait for the updated USA version then flash that?
Thanks again.

Not really anything to wait for. BTU version will work just fine.
If you're that fussed about it changing your csc, extract the cache and hidden images from the xar rom and repack with 7zip then flash with odin.
For what it's worth you must have already had the latest XAR firmware, so not sure why you felt the need to reflash?

It's the WiFi that's the problem. BTU rom has restricted 5Ghz. Won't go above channel 140Ghz. XAR rom unrestricted 5Ghz bands up to 161Ghz or 165Ghz.
If I do what you suggested with regards to CSC would that also give me higher range 5Ghz bands?
Otherwise everything is perfecto. I got it rooted, xposed installed.
I really appreciate all your help. Saved me a lot of time trying to flash Roms like a maniac.

I thought the U.K version is 2 months newer. Now that I think of it, maybe it just came out later behind the U.S version.

I did what you suggested, flashed the CSC and I now have ch 161 working. Less interference with higher channels.
You're the best.
BTW, the BTU firmware has the September security patch.

Cant revert back to the fw originally on my phone (after flashing that ATT pie fw)

N960W, Snapdragon (so no root / bl unlock)
I flashed the Oreo FW after trying the Pie fw from ATT (link was around here somewhere - it required flashing in Odin as well as a local recovery zip flash - two separate files)
Now Odin fails and the phone shows "An error has occ ured while updating the device software" and wont boot. I've downloaded and am trying to flash the official pie update originally for my phone that just came out a few days ago (N960WVLU1CSAA or something like that)
Are you using the patched ODIN? If so it should work just fine. Try a factory reset in Recovery, then boot directly to Download mode and flash it again.

Yea I'm using the patched version.
I will try this next. I flashed the ATT oreo and then XAC version but didnt include CSC this time and it flashed but it boot loops.
I'm currently flashing all of XAC and if it fails then I will reflash ATT oreo, factory reset in recovery and dirctly flash xac oreo.

I'm realizing this now. I flashed N960U fw for ATT and now I cant flash N960W either oreo or pie :/
I just want to revert back to N960W fw, either oreo so I can update via official ota, or pie fw and be done with it -_-
Help!

What is happening? Is ODIN failing? And at what point does it fail? Or does ODIN finish flashing and day "Pass"?

Odin (patched) gets right to the end and fails, followed by the download mode error mentioned earlier.
I can successfully flash ATT fw 8.1.0 (AT&T_N960USQS1ARJA), but cant flash anything else (Canadian XAC 8.1.0 or Pie).
I am contemplating downloading and flashing the ARL1 fw from the same att source

sounds like a bad download. Re-download your Canadian firmware and try it again.
Shouldn't the OP be fleshing the firmware that is for his exact model?

The Pie fw (Canadian XAC, N960WVLU1CSAA or something like that, I don't have my laptop handy right this minute) is for my model (N960W) specifically but won't flash. I'm currently able to flash and use 8.1.0 few made for N960U, which is the AT&T ARJA fw.

I started off with the Roger's fw for 8.1.0 and wanted to try pie so I followed a guide to flash some pie build which I believe was the UK version, and when I realized I hated it, i had to follow a guide to revert back to oreo but a different source, thatz where the at&t oreo fw came from.
Now, i want to revert back to the official fw for my phone so i can choose to officially ota to pie, which is not possible right now because I'm stuck on at&t oreo, and pie just became available for me.

To download it.
The reason I was avoiding this was because Canadian carrier versions (including the Roger's fw) don't seem to have mobile data and hotspot toggles and they also have unnecessary bloat, so I figured if I'm gonna flash a fw, I'll just flash the full Canadian unlocked fw to stay away from bloat and carrier restrictions.

What is your CSC? I'll check SamFirm myself tonight or tomorrow.
Ok so I re-downloaded the Canadian XAC Pie FW, did a factory reset (via recovery), and then Odin (patched) flashed the XAC Pie fw, and guess what!!! PASS.
It must have been a bad download this entire time, or possibly the issue was that I unchecked the option CRC32 in SamFirm.
Thank you guys for all the help. OMG

use your last valid twrp backup from before the issue to restore:
carrier configs (odm)
efs
also when you flash full stock, use csc.md5 and not home_csc.md5 as CSC file.
it migh be good to research what the very latest firmware files are for your device. there should be a july update somewhere. so use that and try again.
if you want and try to fix ure csc issue try to flash zip in:

I am currently downgrading from Beta 7 to Pie 9 BSIV as we speak on my Sprint S10 using ODIN 3.13.1. Did you download the software using Frija? I am also on a Sprint phone flashing Sprint firmware, is the phone you have originally from T Mobile? If you didn't download the firmware using Frija I would re download it using that and try it.

Download most recent firmware using frija. I bet the one you trying to flash is older than what the phone is currently on. You can't flash older firmware no matter what even if using patched Odin.
abl.efl is bootloader, it is normal to fail at bootloader, cause that bootloader is older than the actually one you do have.
You either have to remove bootloader from firmware (if you can), or flash another firmware with the same - or higher bootloader.
Why don't you use stock Odin?

Hello everyone i've been really struggling with updating my phone that i got pre-owned It's a Samsung Galaxy Note 9 (SM-N960U) and I have not recieved updates since I got it the phone is still on Android version 8.1.0 and security patch from 2018 so i've been really wanting to update it to the latest version but I couldn't and i figured out that phones from AT&T only update via their own app or OTA thing anyway I thought of flashing it with a stock firmware VIA ODIN but i checked on sammobile that the note 9 AT&T csc only has 1 update and thats 8.1.0 also so i was wondering if i can use some other firmware to flash it or do i change csc? would that work if i changed the csc or am i gonna have baseband and signal issues? I tried KIES it said it didnt recognize my phone probably because the software version has never been updated and very old , i wanted to flash it to a different CSC than AT&T but i dont think thats a good idea, please help

Kies is for older Samsung devices, Smart Switch is for newer Samsung devices.
Here is a list of firmware at Sammobile that has android 10 for your device. They are for T-mobile but I'm pretty sure it can be used on the AT&T Note 9.
https://www.sammobile.com/samsung/galaxy-note9/firmware/sm-n960u/tmb/
Here is a thread for AT&T note 9 where another user flashed their Note 9 with firmware from another carrier. Use the T-Mobile firmware and follow the steps from post #4 of the thread linked below.

Hello people, having exactly the same problem, so its a SM-N960U phone, unlocked from AT&T. First to say, im not in the US, dont have AT&T sim, the phone is updated to android 10 with 2.0ui, with baseband ver. N960USQS3DTB1.
Now somewhere i read that bootloader must be unlocked in order even to begin thinking of flashind the device, dont know how accurate that is... Id like to ask the Owner of the post, if he was able to make it, to update his firmware. And if so did he indeed succeded from the link above from ep1kku ?

No, the bootloader does not need to be unlocked before flashing if you are flashing stock software, unlocked bootloader is required to flash custom software, not stock software. There are some manufacturers that require unlocking bootloader even when flashing stock software but Samsung is not and probably never will be one of them.
You can flash your device with stock firmware any time you want, provided that the firmware is not a firmware that is older than your currently installed firmware and if the firmware is for your model number or an equivalent variant of your device with a similar model number and the same CPU series.

You can flash your device with stock firmware any time you want, provided that the firmware is not a firmware that is older than your currently installed firmware and if the firmware is for your model number or an equivalent variant of your device with a similar model number and the same CPU series.

You can boot into download mode and it should say whether the firmware is "official" or "custom".
As I said, you can flash stock firmware provided that the firmware that you are flashing is not older than your current firmware, you can't downgrade the firmware, you can only flash an equivalent firmware to what is already on the device or a newer, updated firmware. Your error may be due to this. For all Samsung firmware, the 5th character from the right in the build number is referred to as the binary version. Your currently installed firmware has a "3" for the binary version, this means you can only flash a firmware that also has a binary 3 or you can flash a firmware that has a number higher than 3 but you can not flash a firmware that has a binary that is lower than 3(you can not flash a binary 1 or 2 firmware).
Depending on the specific error that you got, this could be your issue. What was the specific error that you got?

I got you, well iv got into download mode many times, its say official, so in theory i can flash official release right, but keeps ending with that odin error, no idea ... Could it be because im in different region than the device's market, its a US market phone like i said, in from europe

When using Odin, in the box that shows the flashing process, it should say exactly which error you are getting. When I asked what error you are getting, I was not asking "why" you are getting the error, I'm asking what it says in that box. Post the exact name of the error. Try to flash the device, while it is flashing, watch the dialog box in Odin, when it gives the error, take note of exactly what the error is, you can scroll up and down within the box and read all of the output data in that field.
Yes, it could be due to being from a different region but I doubt it. It could also be because your device is a Snapdragon version but the firmware that you are trying to flash could be for a Exynos version instead, or vice versa.

You still aren't telling me the SPECIFIC error that you are getting in the dialog box in Odin. That has been the most important question to understand your issue but you keep dodging it. Flash the firmware, watch for the error, take note of exactly what error it says it is, then post exactly what it says the error is. If you can't post that then there is no point in replying.
If you are trying to flash the device in a different region, you may not need to flash the whole firmware from the different region, you may be able to flash just the modem.img from the alternative firmware. To do this, extract the firmware, find the modem.img then convert that modem.img into an Odin flashable .tar using 7zip with its highest level of compression, then flash the modem.img.tar via Odin.

I added to my previous post.
Strange, your screenshot doesn't show an error, it just stops without giving an error.
I'm assuming that your firmware came in multiple parts with some CSC files? If so, try flashing without using the CSC files.

Give me a link to the firmware that you downloaded and I'll compare to see if it is supposed to work.

Alright, https://www.sammobile.com/samsung/galaxy-note9/firmware/#SM-N960U this is without the carrier, if you put at&t in search menu, you will see that only 1 is available, with android 8.1
So i tried U1, version at&t https://www.sammobile.com/samsung/galaxy-note9/firmware/SM-N960U1/ATT/#SM-N960U1 also didn't work, i tried T-mobile on same U1 model, also didn't work. Everytime same error/none error like on the screen shot
