How To Guide OTA and Non-OTA Firmware for S22 Ultra SM-S908U and S22 Ultra SM-S908U1 Versions

Search This thread
Just giving heads-up the Duo video quality is way better than the Samsung Video call thats built in , plus Duo is universal for all phones, Samsung Video isn't, and there's no lag in Duo video, just thought i share with you guys , i personally disabled the Samsung Video and use the Duo video.
No one I know uses Duo or even knows what it is. For most people that have iPhones, I video chat with them using Whatsapp Messenger, never failed me, but it hogs a lot of battery.

If more of my friends/family used Duo, I would use it too.

Link them it let's you link them so they can download it , i mean i know some might not use it, but i don't use video calls a lot only a random thing with only my family.
Edit: But i do understand preference depending who you hang with.

I use duo with everyone. I have a few friends with iPhone's, and since I can't get facetime, they've all just downloaded duo. The video quality is pretty good. It definitely didn't use to be. It was pretty awful for a while lol.

Hi everyone. Thanks for all your efforts. I want to share my unexpected results and get your thoughts.

Verizon finally unlocked my S22 ultra so I flashed U1 AVE4. Did wipe in recovery then flashed all files w/ Odin (btw for some reason v14 doesn't like my USB ports so I use v13). I no longer get VZW boot screen (using VZW sim) or VZW bloat which is great. Only VZW crap is visual voicemail so I use Google Voice.

I'm shocked I'm not getting the VZW boot screen. I never removed my sim during the whole process. Also, I'm not getting the June OTA but I was promoted before I flashed. Will June update for U1 roll out at another time? That may be great because I've done this type of flash before, gotten a VZW OTA and it basically set my phone back to carrier locked firmware.

Anyway, thoughts?

from U1 version, now swtiched to U via dirty flash. no bloatware by carrier since i used outside country sim (which i prefer and better for me) the only problem facing right now is before on U i am seein signals sign when its 4g or 5g but right now even i dirty U version on my previous U1, can still only see LTE sign. any reccomend? should i start from the scratch clean flash the U firmware again?

Look at post #1530 from venom0642 in this thread and see if that helps.

I got the T-Mobile AVF1 update today...I've been patiently waiting for this update since couple of weeks

Fingers crossed that this would finally fix the dreaded "Warning: Camera Failed" issue. If anyone has this issue (happens when on 5G), the workaround is to disable 5G and enable LTE only mode or Airplane mode. very annoying

    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.

    Ok what is going on here???? Venom actually told what he did. Are you feeling ok??🤣🤣🤣

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

    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
