    @ EVERYBODY AROUND : ENOUGH OF OFF-TOPIC

    If you pay attention, you'll notice that the thread is being heavily derived from its main topic which can result in a heavier cleaning if it continues that way.

    PLEASE consider staying ON-TOPIC and let the XDA experience continue to be as joyful as it always was !

    Thank you all for your collaboration.

    So I decided to send my S21U to Samsung for a battery replacement, engineers have confirmed battery is draining faster than usual, thus faulty, and is been replaced under warranty 🙂 so for anyone who's thinking something doesn't seem right with their battery, get it replaced.

    I've had no issues with CVD2 (JUST BATTERY DRAIN). everything is blazing fast and responsive and smooth.

    In this thread, you can discuss and share the Mega links of new firmwares (OFFICIAL STOCK) for the Galaxy S21 Ultra 5G!

    How to flash the firmware to your phone:

    Odin.png


    1. Extract (un-rar) the firmware file (i.e. to folder C:\Odin) ***
    2. Download Odin v3.14.4
    3. Extract the Odin ZIP file (i.e. to folder C:\Odin)
    4. Open Odin
    5. Power OFF your S21 Ultra 5G
    6. Reboot Phone in Download Mode: Connect USB-cable to your computer. Hold down "Volume up" and "Volume down" at same time. While holding down, connect the USB-cable to your phone. Or use the command "adb reboot-bootloader".
    7. Wait until you get a blue sign in Odin
    8. Add the firmware files to their designated slots (AP in AP, BL in BL, CP in CP, HOME_CSC in CSC). USERDATA stays EMPTY!
    10. Click the start button, sit back and wait few minutes for the device to automatically restart.

    *** You can always find the LATEST firmware in message #2

    Greetings to all. Just dropped by for a little more "Unsubstantiated Update Claim Game" or UUCG for short, cleaning! Since this appears to be an ongoing matter, I will be happy to just drop by everyday and remove these little buggers with immediate effect in an effort to keep the thread on topic, which is why some of you reported these in the first place.

    This way, it will eliminate the reports, and save our Mods, me in particular, extra typing practice, even though I need it!

    Cheers to all: Badger50

    For the love of Pete!! Thread cleaned again!
    Can we PLEASE stop with all the unnecessary back-n-forth with these updates!!!! I keep getting reports from various members about constant OT, griping, whining, this that, he said this he said that, and disrespectful and snarky comments CRAP!! So from now on, if I have to action further reports from members that have been repeatedly warned, I will take up the issue with you regarding XDA Rule #2 for member conduct via PM, which can/may result in disciplinary actions regarding your account.

    So Please, keep this thread "ON TOPIC" out of respect for the OP, and for all other XDA members. THANK YOU!!

    -Regards: Badger50

    Moderator Announcement

    I've cleaned this thread from all the off-topic posts and flamings; my cleaning included all timezone "discussions", not-firmware or S21U related posts, attempts to moderate the thread and much more. Actually, I must say I cleaned the thread AGAIN after all the attempts of my team mates @Badger50 and @V0latyle - and the expectations I'd to read here that the thread gets automatically cleaned e.g. in the morning simply shows disrespect to moderators by wasting their valuable time that could be much better used.
    It finally got too much now! I've notified everybody whose post(s) got deleted i.e. everybody should be aware.

    I'm requesting my team mates to inform me about anybody who still continues with this type of posting. In turn I'm going to revoke the members write permissions in this thread, initially temporarily for 2 weeks; however, the member will permanently have read permissions i.e. being inform of any firmwarm update. In case of recurring spamming, I'm gradually increasing the write ban to 4 weeks to eventually become permanently. I hope that this friendly warning helps to now keep the thread focussed. Thanks for your cooperation!
