Hello,
I flashed my factory unlocked Samsung Galaxy S8 with the Verizon carrier firmware awhile back in order to gain some carrier features. Since then I have gotten a new device and want to flash my S8 back to the unlocked firmware. Flashing to the Verizon firmware was uneventful, but trying to flash it back to the factory unlocked XAA U1 firmware always results in a SHA256 Invalid error right after I click Start in Odin. I've tried the Prince Comsy version as suggested on a few threads, but it just gives a failed to write error. I have also tried another firmware version download (from Updato), different versions of Odin, and different PCs.
Any help would be greatly appreciated.
Thanks.

Anyone?
Still haven’t been able to find a fix for this. Tried with a patched version of Odin to bypass the SHA256 check, but it’s giving me a different error. I’ve attached photos of the exact error messages below. Surely someone here knows something about this?
download latest firmware
its maybe because you are flashing old file with v1 bootloader

Already using the latest from Updato. Thanks though.
Still haven’t found a fix for this. Any suggestions would really be appreciated. Not sure what else to try here.

Well, you were pretty close. For anyone who is interested, the issue I’ve discovered is that the current Verizon firmware has bootloader v4 on it, and the latest U1 firmware only goes up to bootloader v3. Looks like I’ll just have to wait it out.

Yes, I was getting that error because the unlocked firmware I was trying to flash had an older boot loader than the Verizon firmware that was on the phone. Had to wait until an updated version of the unlocked firmware was uploaded.

I don’t quite remember, I sold that phone soon afterwards. It has something to do with the name of the firmware, I’m sure Google could help you there.

Hi,
Need your help. I have a Note 4, Sprint locked, model number SM-N910P, Lollipop Version 5.1.1. I would like it to be unlocked so I can use it in the Philippines. I see a thread that I need to downgrade the ROM then use SSU.apk. When I am trying to have it downgraded, Odin was not able to finish the Job. It always fails with and NAND Write error (auth).
I tried all SM-N910P 4.4. versions and all Odins versions but no luck.
I appreciate any responses and assistance with this.
Thanks,

Youre on the OG5 bootloader and you can not downgrade from that bootloader. not even to 5.0.1 lollipop bootloaders.
Might wanna go into Security and uncheck Reactivation Lock as well.

Hello,
I currently have an unlocked G930A that is running on 7.0, I am using the T-Mobile carrier and I would like to flash to the T-Mobile rom. I know it was possible on marshmallow but I couldn't find any posts regarding 7.0.
If I follow these instructions

Thanks bro! You know which version of Odin to use? I'm on 3.12.3 and it's giving me invalid sha md5 error. File is fine. Other guy mentioned Odin from Verizon thread. Couldn't find it
Edit: Found it! It's PrinceComsy Odin 3.12. It worked perfectly! However, now my fingerprint sensor doesn't work. Is that because I didn't flash bootloader? If I flash just bootloader, will it still wipe the system?
Edit 2: Goddamnit Samsung Pay isn't working either. Says I made unauthorized modifications.
Final Edit: So apparently you have to flash Bootloader as well to get Samsung Pay and fingerprint sensor to work.
Basically, Download PrinceComsy's 3.12 Odin from Verizon Root thread. Then flash the latest G930T ROM from SamMobile. Tick BL, AP, CP, AND CSC. Make sure you ran Odin with admin privileges. It'll wipe internal SD so back that up.

Hello everyone,
My device got bricked since I flashed it with Odin yesterday, and now even I re-flash using official firmware, it failed as well……
The model of my phone showing in Samsung official site is G935-P (Sprint version), But that shows on download mode is G935U, maybe the eBay seller had flashed it with G935U firmware…
What version of firmware should I download to recover the OS now? And what could I do to Un-brick my device? Someone who could give me some advice or assistance? Thank you all!
Try Smart Switch. It will automatically download the correct firmware for you.
Hmmmmm what update were you trying to flash in odin and i would check the back of your phone bc it should say exactly what model it is (935x) just to be sure then flash the LASTEST firmware to get yourself up and running then if you want Ufirmware go ahead flash that

Thanks, I've tried Smart switch, but it doesn't work, fortunately, it's resolved by flashing the latest G935U firmware

You're right bro, it was resolved by flashing the latest firmware of G935U, thanks a lot
No problem glad I could help
Hi,
I am trying to flash my SM-G935A AT&T S7 Edge (not carrier unlocked) with the new SM-G935U firmware (G935UUES4CRG3/G935UOYM4CRG3/G935UUES4CRG3/G935UUES4CRG3) that I dowloaded for my US AT&T S7 Edge. I upgraded my S7 Edge to the latest Oreo firmware via OTA around a month ago.
I used SamFirm to download the image to flash. Anyhow, even though I put every file into its respective category on Odin 3.13.1, I get an "SHA256" mismatch error. I've seen some instruction that say to only add the AP file onto Odin and others say to use the prince cosmey version of Odin. What could be the problem? Does the phone need to be carrier unlocked? Is my firmware too new or of the same version? Do I need to use the prince cosmey version? Is it not possible to flash the g935u firmware onto a g935a phone? Should I use another download source? Should I use the slightly older G2 firmware? Anything else I should consider?
Also, I noticed that I could not download firmware for the SM-G935A using the ATT code with SamFirm? Any reason as to why?
I realize that there are many other threads that touch upon this problem but they are either with a different edition of the phone, firmware version or some other variant. I'm posting a new thread because I want to be as thorough as possible and make sure not to brick my phone by receiving safe advice before moving forward. Thank you for your time!
Below are the SamFirm download details:
SamFirm v0.3.6.0

Correct Thread?
Did I post in the wrong thread or something? Is that why there is no response? Would someone be kind enought to point me in the right direction if this isn't the right section for such a question?
Thank You
Hi did you find any answers to this issue? i got stuck on same point as you...
Stock Odin checks the version on the device and fails because the U version doesn't match the A version you are "upgrading". There are patched versions of Odin that skip this check, and that is what you need to do a cross-carrier upload.

Use a patched odin to flash the firmware, it will go through.

Hi, yes it worked!
I'm wanting to return my phone back to stock. Has anyone had experience with this website. So far it's been alot better than sammobile. I've flashed a stock firmware from this website onto my tablet and it has worked fine.
I'm causious with the S8 as its my daily phone and don't want to brick it.
Also, if anything bad happens during the flash process using ODIN is it easy to return back
(I'm guessing ill just have to flash TWRP - This happened on my old S6 and worked fine)
Thanks
EDIT: The website worked fine for me and i was able to download a firmware and flash it correctly. Its much better than sammobile imo.
So, for anyone wondering weather this site is good - its great
Ive tried it now and i got a error message

You are flashing an older version than what is on you phone. You can not downgrade firmware.
For latest firmware you can use samfirm or frija to download firmware.
spawnlives,
Thanks for your feedback. I've manage to flash the stock firmware and it all works fine
