You can't install any firmware for a S908U/U1 on a device that isn't a S908U/U1 and vice versa.
My s22 ultra baseband version is S908U1EU2AVDC. It's an unlocked phone bought from usa. can I install the Indian software version on this phone for use in India so that we can get the call recording feature enabled.

Have you read the previous comment? They Said No. You cannot flash just any firmware on US model. Just choose only U or U1 version that's it

I read it just fine, I left it for you to research (Because I wasn't familiar with the version of the Indian devices). The firmware for Indian S22 ultra's is S908E, which going back to my original post you are not able to install on a S908U1 device

What is the difference between bands on a usa model s22 and Indian model s22. I can see a small chip installed on usa phones on the right side border of usa s22 phone in lower 2/3rd area.
Which s22 is better to buy in India a usa version or Indian version.

Obviously, it's better to buy an Indian version as it will come optimised for the Indian Market...

Even if we go to samsung service centre in India and get it installed from them they would also not able to install on usa model phone.

You are right my dear friend but I want to use my phone in usa and when I am in India I have to record my calls which I am not able to do. I have also found that usa models are mostly superior than Indian versions as they have extra network chips installed which offer better networks in basements. Indian version phones have low Bands in them.

Dude, you are asking the same question again and again. SM-S908U1 or SM-S908U cannot be flashed with any other model firmware period. It doesn't matter if you flash or Samsung service center flashes it. If call recording is important, buy an Indian model S22U and sell the USA model.

    See Post #2 and #3 for the Links to the Firmware

    All of the firmware posted here can be flashed on any U or U1 Device. Each of the firmware's are NOT carrier dependent and only has carrier labels listed in order to have an idea if you might get OTA when you flash it.

    The firmware packages house each of the carrier's information, features, bloat, splash screens etc. (That's why they roll in at over 7Gb). When you flash a firmware the installation package reads your SIM, determines what carrier you're using and then installs the "package" that's designed for your carrier​


    S908USQU1AVA7 (Totally fake Firmware. I just made it up for example purposes)
    S=Galaxy S
    908U or F etc, the model of device
    SQ, FX etc = CPU and model specific
    U,S,E = Update, Security, Engineering, respectively
    1,2,3,4,5 etc = bootloader revision (This is important! You cannot go to a previous revision)
    A, B, C etc = Android version
    U, V = Year (U=2021, V=2022 etc)
    A,B,C etc = month (January A - December L)
    1 - 9 and then A - Z =build compilation. This basically means how many builds there are in a month. They start at 1 and go to Z
    So S908USQU1DVAM would be
    S908-U-SQ-U-1-A-V-A-7
    S908U (S22 Ultra Carrier version), SQ (Snapdragon), U (Update), 1 (Bootloader version), A (Build 12), V (2022), A (January), 7 (7th build)

    BL- Boot Loader
    AP - Application Processor (also termed PDA), this is the system partitions, recovery etc,
    CP - This is the Modem
    CSC - Consumer Software Customization. This is all of the stuff that contains the different carrier features, wi-fi calling, APN stuff like that. You'll notice that this file is getting as big(If not bigger) than the AP file with the system information.
    HOME_CSC - This is still the "Same" as the CSC, except it retains the CSC information that is flashed on the device. It wont wipe your device like the normal CSC will. This is part of the package in the OTA that doesn't wipe your phone
    USERDATA - Carrier files, this "Brands" the device to your carrier

    How to enter Download Mode:

    Turn off the device.​
    Connect USB cable to your PC (Leave it disconnected from the phone)​
    Press and hold down the Volume Up and Volume Down buttons. While they are still pressed, plug in the USB cable into your phone.​
    The phone will go into download mode press volume up. In Odin you will see that phone is added.​

    A decent writeup on how to use Odin:

    ***You MUST use one of the Patched versions of Odin in post #2 or #3 when flashing***


    Dirty Flash:

    I would only do this if you are having to manually update to the newer firmware and would not do it if you are coming/going to U/U1 or from beta firmware or if you are on an old firmware. I'd also highly recommend doing a back up prior to the doing this​
    Load these into Odin​
    BL​
    AP​
    CP​
    HOME_CSC​

    Do NOT flash CSC or USERDATA (If it's in the download package), either of these WILL wipe your device.​
    This is a "dirty flash" and these can sometimes cause issues. Keep in mind if things start going sideways and stuff starts not working right, your first step to a solution will be to wipe the device.​

    13/OneUI 5.0 BETA - S908U1UEU2ZVH4 (AFH) and a MIRROR (Faster) Thanks @lexcyn
    You MUST be on S908U1UEU2AVF7 in order to update to this beta.​
    This is BL 2 so you can go back to stock, but if you do it's HIGHLY recommended to not dirty flash (It might not let you so be prepared to wipe)​

    I sense trolling lol. All needed info has been posted on this thread except new releases. People get too emotional over technicalities. Recommended thread lock except new releases.
    I would never support locking the thread, it's how everyone learns and has some fun too

    How do i know which firmware to download? Im a complete beginner... i have an att locked (making payments) 22 ultra sm-s908U. I was told to get the u1 firmware because its unlocked and i can use rcs thru jibe not att, but i also was told i need to get the firmware that matches the model number which is U. I may be overthinking, but it's confusing. And all the U options are labeled by carrier, there doesn't seem to be an unlocked firmware for my U phone. And if i were to get an U1 firmware, there are a few options with no explanation on the differences and which to get. Don't get me started on the advice to look for XAA firmware, because i don't see that anywhere lol. Apologies if this seems ridiculous, i just don't want to brick my phone
    There's VERY little chance you'll brick (The only way that I know you can is pulling the USB cable when flashing), that aside, it'll just error before the flash could happen.
    That being said, If you have a S908U or S908U1 device you can flash ANY of the firmware on this post. The firmware is not Carrier agnostic, the only reason there are carrier tags next to the posted firmware is to let people if they flash a specific one whether or not that is the current stock one and will get OTA in future releases.
    Most of that info is in the OP (I think.......), and if you're not too familiar with the process, I highly advise taking the time to read thru the pages, almost everything you'll need to know has been posted.
    If you can't find something ask, most everyone is super helpful
