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.
Hey thanks again.

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.

Hi I'm trying to flash the T-Mobile firmware from sammobile.com, but whenever I try, I get an error at 32% when it says Installing System Update. I attempted to flash CSC,AP,BL, and CP with it saying PASS in Odin. I really need the T-Mobile firmware and am wondering if it is possible to do? I determined that I cant install CSC files and get the error when I try. Any Solutions?
SM-G950U
Odin 3.12.3
T-Mobile Firmware:
PDA: G950USQU1AQD9
CSC: G950UOYN1AQD9
I'm having the same problem with an ATT phone flash with the US "U" unlocked version firmware. When I don't flash the csc it will start up only with the USB plug in but shut down after the beginning startup
Search for a "modified Odin". It was what I used to be able to flash unlocked firmware on a 7 and 7 edge a few months ago. The "normal" Odin wouldn't let me do it, but the modified one did. Though you may need to wait until it's been updated....I haven't checked it in awhile.
Still no solution to avoid the error to 32%?
Try this Odin. This is the one I used to flash the Canadian firmware on mine.
I managed with odin version 3.12.5! But only with BL AP and CP!
When I add CSC I get the error at 32%!
So a priori everything works, I no longer have the Verizon overlay (nor the logo at startup) more by cons I have duplicates in the settings menu ...
What is the CSC file?

The Canadian firmware you got it or? On sammobile I find it not:
https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U/
The Canadian firmware is stock or operator?
I would have access to all the bands?
Its the firmware with the "w" at the end. Please read this thread for all the information on doing this and make sure you want to do it.

so to do this we actually have to go to the canadian firmware first, do the csc change then flash the Tmo firmware? You can't just flash the Tmo Firmware via the modded Odin? Just to save confusion.
I would imagine it's worth it just to get the proper network options, VOLTE, WiFi calling and such.

This is the exact thread that I used. Follow the steps and you can skip engboot. If you flash the full Canadian firmware, its impossible to reverse. So, only flash whatever is in the steps. I successfully went from Verizon To T-Mobile and then back to Verizon. https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487

I have a N950W (canadian model). Origina firmware BRA5 (latest Canadian release)
Used Odin to BRA8 then update to CRA5. Works good, however I need to go back to official Canadian release and I think it may not be possible since its BRA5?
Does BRA5 and BRA8 have different version bootloader?
Can I somehow downgrade to BRA8 but have the model go back to N950W and be recognized as a Canadian device? I am missing some needed carrier options.
Thank you for reading.
I did the exact same thing you did. Turned my W into a U model. I believe we were on 3BRA5, 3 being bootloader 3. That would mean you can flash back with no issues.
CRB5 is working great for me, but I did lose VoLTE and Samsung Pay on my Telus version (after I flashed it to a U).
Someone else chime in and correct me if I am wrong, but you should be able to flash back to W software any time without issue, as long as it's a bootloader version 3 version.

Yeah the lack of VoLTE is killing me at work. I can't flash BRA5 (I think bootloader is older). I am thinking I can maybe flash BRA8 with Canadian CSC and that will bring it back to N950W. I'm not sure though. Can someone confirm?

I just double checked. It's 3BRA5. That's bootloader 3, so you should be able to flash back to 3BRA5 with no issues. Again, a second opinion would be good. I don't want to be responsible for you bricking your Note, lol.
I don't think you can change the CSC of BRA8 to a Canadian CSC, as the multi CSCs in BRA8 are for USA carriers only.

How I remembered it as is Comsy Odin is for going to a non-carrier U1 firmware, while regular odin is for going back to a carrier firmware.
Comsy --> U1 Firmware > Success
Comsy --> Carrier Firmware > Fail
Regular Odin --> Carrier Firmware > Success
Regular Odin --> U1 Firmware > Fail
Hi, I have the Singapore firmware on my device (non-rooted): XSP
This firmware is absolutely ridiculous when it comes to updates. I am currently Sept 1, 2018 security patch, and that is the latest available for this device.
Is it possible to flash another exynos firmware from ODIN to my device WITHOUT factory resetting my phone, so my data and apps don't get affected? Can I just download the UK version, for instance, from Sammobile and flash it without affecting my data?

Yes thats no problem, just make sure you flash home CSC, if you flash CSC it will factory reset your devcie.
Thanks! I'm guessing it's not considered a dirty flash or anything right? If I install another firmware on top of XSP and flash csc_home, can it effect performance negatively?
What's the best recommended firmware to flash that gets the latest updates to replace my current XSP?

You can flash ANY firmware where OXM is mentioned in the CSC
Flash AP BL CP HOME_CSC_OXM with Odin 3.13.1 to your device: your data & CSC (XSP) will stay intact.
You can't change CSC on your device; if you flash i.e. the latest UK-firmware (BTU/XEU) and that build is NOT released for CSC XSP, you won't get OTA's to your device and you'll have to flash later FW's again via Odin.

Does this mean you can use any CSC from other official firmware and the drawback is that you cannot get OTA?

If your CSC contains OXM (check with *#1234# in your dialer), you can flash every OXM-firmware released.
But: if that build is not released in your country, you won't get OTA-updates.
If your country will get a newer build, and you flash that to your device, than you'll receive OTA's again...
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.

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.

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:
