Yes! I like the slightly boxier sides! It started to get too rounded on front and back. As much as I'm a note person, I which they'd lose the pointy corners. Make the slightly rounded. Not as drastic as the S-line (S23 and S23+) but something. It would pprobably also help it be more durable during a corner drop

I am upgrading just for battery life alone. The SD version of the s22 just has been a disappointment for me from the start when it comes to battery life. Hopefully the S23 Ultra will bring back better 😉
Agreed. Slept on it. I definitely need better battery life and a smoother experience. Based on some reviews so far, it's quite a large upgrade.

Thank you for the info, I have an SM-S908U1 with XAA/XAA CSC code, I hope someone can help me with which CSC should I patch it with to fix poor network issue.

To give more context, I live in Morocco, my phone used to work fine, I'm not sure what CSC code it has then.
I travelled to Turkey and used a Turkish SIM card there, it worked fine. I also installed the official January update while I was there.
I came back home and put back my Moroccan SIM card and network became really poor, barely no signal, and even when it shows LTE, it barely works.
I tried all the normal things, from resetting network setting to even factory resetting my phone, and I downgraded android to November's security patch version (using ODIN and ROM for SM-S908U1 XAA) in case the issue was caused by the newest update. None of those worked.

After a lot of research online, I now thing the guy I purchased the phone from maybe patched the phone but whatever he did was overwritten while I was abroad and maybe with the software update.

Now I wish someone can point me towards what CSC code should I patch, Morocco's CSC is MWD but it's for SM-S908E with Exynos and I'm worried downloading and patching it with that one can break it.

Thank you for reading all of this even if you have no clue about it :D

Apologies if I'm in the wrong place. I purchased a S22 Ultra on Facebook. It was supposed to be unlocked but it was not. The seller has washed his hands of it. I paid to have it unlocked for other carriers however I can't get updates because the original carrier still has it locked in their server. Can I flash from s908u to ans908u1 and get firmware and security updates OTA.

Find it funny the S23 line up doesn't drop till 17th and has gotten an update, yet they are sitting in boxes not shipped yet. (Or at least mine hasn't) 😂😂

Might see if Kangi will create it and we can maintain it. There are enough of us here with knowledge to help out. But Kangi has been busy and I can understand that. Hopefully Venom will help too.

    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.​

    Bootloader 2 - If you are on a Bootloader 2 firmware you can NOT go back to a Bootloader 1 firmware, there is NO workaround. See Post 1 to determine which bootloader you're on

    BETA1 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)​

    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
