Downgrade Galaxy S8 - Samsung Galaxy S8 Questions and Answers

Hello out there I have Samsung Galaxy S8 SM G950F with Android 9 build number G950FXXU5DSJC I got a software (to downgrade to Android 8) with PDA: G950FXXU4CRK1.
I have tried to flash it with ODIN, but FAILED! I get a message SW REV. CHECK FAIL (BOOTLOADER) DEVICE :5, BINARY:4. Can anyone help me on. Thanks Alex

You can not downgrade versions on Samsung devices due to bootloader ( binary ) numbers. You can flash the same or higher only. This is why you are getting error message.

If I have a AP: G950FXXU1AQK7 android ver 7, and I want to upgrade to 8; can I use ver. 8 AP: G950FXXU4CRK1? or it have to end in ....QK7 too? Thank you

Oh dear sorry to hear that you have been cheated. N910v is verizon note 4 and the 1 you have is spoofed n910f its very easy to spoof from build.prop in system and by z3x box.the download mode is correct model shows there of motherboard.
You cannot flash n910f firmware on n910v model it will fail in odin you have to download n910v firmware from www.sammobiles.com/firmwares
But i suggest is your current n910f firmware is running fine then dont flash n910v firmware cuz your phone will filled with verizon bloatware apps.and your phone will run very slow and laggy.
Or much better if you return this phone to guy and exchange with another one shows in download mode n910f or n910c international model

Q: if I use a verizon firmware, do I have problem with cellular service (sim card)! if the firmware is from USA and I'm in Algeria?
No you will not going to have any cellular issues cuz verizon models are global gsm sim unlocked but you will be able to use 3g hspa+ data only the 4g lte will not work.and also you have to make apn settings manually to get data work.

does this firmware worked with u?
I have a similar problem with my N910F which registers as N910V in recovery and download mode.
I tried playing around installing a new firmware from Dr Ketan Rom and although it installed fine, I can't get the phone to recognize my sim card (Ghana). It says 'no service' and/or 'no sim card.'
Now I tried flashing with N910V stock firmware and I get stuck in a bootloop.
I also realised that the IMEI of the phone is fake and an IMEI check says it is a Samsung windows 7 phone.
Any help?

Try flashing the 910V modem immediately after Dr Ketan's ROM, then reboot. If that fails do the same using the Verizon's firmware. And as it was mentioned above you will be limited to 3g + speeds.

Your phone is refurbished N910V verizon note 4 and fake N910F software And fake sticker at back side of battery.
If you want upgrade to 6.0.1 you have to download N910V firmware from sammobiles.com thats your orignal motherboard model.
but keep in mind you will lose 4G/hotspot/ and much more stuff if you upgrade.i suggest you return this spofffed note 4 and get another new device and if you cant return use at it is on 5.0.1 lollipop dont upgrade.

Looking for firmware for US unlocked S8 SMG950U1ZKAX

Anybody know where I can find the firmware for
US Unlocked Galaxy S8 (Model on box: SMG950U1ZKAX)
CSC: SMG950U1OYM1AQE3
PDA: SMG950U1UEU1AQE3
I found a couple of versions on Android Nougat on Updato, but I get the fused 6 > binary 1 error on phone (AUTH error on Odin, yes, I'm using the Samsung drivers), and after a little research, it appears that It needs to be in the version my phone was before, so I believe I need something with Android 9.

Samsung S8 Downgrade 'SW REV. CHECK FAIL(BOOTLOADER)' error

Hello friends;
I want to downgrade my Samsung S8 from Android 9 to Android 8.
I downloaded 3-4 different roms, i got always this error: SW REV. CHECK FAIL(BOOTLOADER)
Installed current version on my Samsung S8 : G950FXXUCDUD1
According to the information I have reached;
If the bootloader version is different, we can not downgrade.
G950FXXUCDUD1 : the letter C here is the bootloader type, I have this rom right now.
eg; I want to install G950FXXS4CRLB rom: 4 and C are incompatible
My current Android 9 Rom: G950FXXUCDUD1
Latest Android 8 Rom: G950FXXS4CRLB
So how can I go back to Android 8 in this case?
I need your help guys.
I do not have too much information.
Thanks in advance
You flashing wither the wrong firmware or to low of a revision as in trying to downgrade and you cannot The 5th to last digit must match what's on the device or be greater
