Can you explain me how to change csc? Thanks

Get that app,you need a pc
Open the app,connect your phone and at the CHANGE CSC put DBT (for the fastest updates possible) and then click on CHANGE CSC and complete this process without restarting 3 times and then restart (for me it didn t worked first time so i did it 3 times and it worked,you cannot break anything for doing that)

Edit: Also in developer options you need to enable usb debugging and when you connect the phone a pop up should appear,if not,just try and do the process maybe it works)

My device is ZTO and I am using a DBT ROM, I finally got the update via OTA after using the SamFW program!

Just to clarify, it is necessary to pass the DBT ROM with Odin and then use SamFw to change the region, as it is likely that some will try to change the region and it will not work.

Edit. Seems to be better today, may be just need to settle down.

Will see how it goes for a couple of days more 😉

So I managed to switch to DBT with the above mentioned tool ( Although it said some pass and some fail)

Got the update and stuff.

Now Twitter scrolling is very laggy and some apps seem laggy so not sure if it's an app issue or something else.

Anyone else have issues?

Done wipe cache and repair apps.

Guys can you try something?

Play a video in YouTube and minimize the video. Should be a smooth animation.

Now open the comments of the video you're watching and mimimize the video again. It's a lagfest on my S22 Ultra and I think I had this issue on my S21 Ultra too.

It's not the App version. Tried it on my S10+ (but it has Android 10 installed).

Maybe it's an Android 12 issue or an S22 issue.

    OK guys, I think I found a serious bug on the latest CVHI update.

    I got camera app failing when switching lenses several times since the last update and I am getting the attached. Usually happens when switching from 1x to 3x

    Anyone else having experienced this issue?
    I Have this problem constantly, its a fisical problem on Camera, turn off your phone, make some punchs on this, and power on your phone. Its woks for me.

    In this thread, you can discuss and share the Mega links of new firmwares (OFFICIAL STOCK) for the Galaxy S21 Ultra 5G!
    NO CUSTOM ROM's and/or ROOT-talk

    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

    You know One great thing noticed in OneUI 5.0 is that battery killer shacking wakelock finally completely removed by Samsung. Just 5 minutes ago it came to my knowledge while digging oneui 5.0 for development purpose.

    @Badger50 sorry for posting oneui 5.0 related stuff but indeed this matter most discussed in this thread so sharing good news that going to happen in future for all! This is something that users on this thread like to hear too!
    Kindly feel free to remove if you find it inappropriate.

    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

    I love the tension when an update comes. The anticipation of an update, the climax when it's released and then the oh....that was crap. Cycle restarts.
