Hey Venom, I'm on locked AT&T U on the same device but I manually updated to 2AVDI via OTA. Can I dirty flash back to 2AVDC using the firmware from post #2 that you used?
Why it's random but yes and no, Yes can flash with not losing data maybe or can bootloop you to recovery and would then lose data and would have to factory reset, that's why I said yes maybe cause it's random can go either way, Do have a question why would you want to go to 2AVDC which isn't official for AT&T meaning you will lose OTA, plus AT&T is on a higher build 2AVDI which i personally would stay on.

Because my battery life seemed worse after updating. But I have wiped cache and recalibrated my battery and it seems to be performing even better now, and my battery stats are back to normal like when I was on AVCJ. No need to flash backwards anymore.

Thanks for your response!

5 hours of SOT and near 50%, I'll take that any day.

Hi all,

I recently purchased an Ultra S22 SM-S908U1 and this doesnt seem to support the 5G network in Canada/Telus. My question is, will it be possible to unlock the band if flashed using the Telus CSC?

Do the unlocked phones on Tmobile network get the integrated video calling and wifi calling? I want to order a factory unlocked specific color but only if all my plans features are accessible.

I'm not 100% (I assume they do) but even if they don't you can always flash a Carrier firmware and have those features

Can we have the call recording option on Samsung s22 ultra bought from usa and used in india. What firmware do we need to load and how do we do that. Will the Samsung service centre install the Indian software on usa model and will that work.

I didn't understand. I just wanted to know how can we enable a usa version s22 ultra not having a feature of auto call recording record calls like Indian versions. Do we have to install the Indian software on usa models.
You can't install any firmware for a S908U/U1 on a device that isn't a S908U/U1 and vice versa.

    At this point, they might as well skip June and release July for U1! ;-)

    Whatever bloat your current Sim has, you will get. I believe even if you dirty flash it will detect your Sim regardless. If I'm wrong someone will jump in.

    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.​

    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
