You are correct. My baseband is Zuka. I will try to do what you suggested and revert.

Also is it advisable to reflash the entire file because it has updated in parts.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] enjoylife1788:
So it worked. I flashed the CP file and baseband is updated and even software update says everything is OK.

Thanks for the tip. I am just thinking to reflash the file as this one could create issues as it was flashed improperly.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] enjoylife1788:
Yes it worked for me too. The baseband wasn't properly flashed. Reflashed the cp file and good to go.

But doesn't it matter which firmware is installed as long as it is a multi-CSC?

I usually have DBT CSC, now I have Multi-CSC AUX installed, everything is going great. Are there any advantages to installing the DBT, if available or unnecessary because the same?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] enigmatron:
Yes that's correct about the multi csc, I haven't downloaded the firmware from Sammy so not sure on the csc, if someone could confirm I wouldn't mind downloading and installing it. I have a few issues with the beta 2
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tester25:
Installed first Beta #1 and then Beta #2 as the tutorial of this thread says. Now, as German official Android 12 release seems to be out, my Note 20 Ultra 5G doesn't find the update, neither OTA nor via PC/Smart Switch (I'm on SP1A.210812.016.N986BXXU3ZUKA now).

So, how to update from this Beta #2 out of this thread to German DBT (N986BXXS3EULH) Android 12? Which is the correct way to update via Odin without losing data and apps?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] woodchild:
I would flash the BEta3, then the beta4. Flash with Home CSC to stay data intakt. Flash via Odin
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tester25:
Thank you, but unfortunately there is no beta 3 or 4 (it's an Exynos device). So I will try to flash the official Fw files with home CSC via Odin.

Trying to update my N20U to the first beta from November (XEF) firmware via adb but mine stay veryfying update package. Anyone have an idea about the time it take to flash it ?

I am yet to receive the November patch, can anyone share so I can update and try it again.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] antisocialbratt:
Grab November file from sammobile. It will wipe the whore device though. I would suggest just wait a few days. Nov patch is rolling out and then you can install this update on top
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] antisocialbratt:
Updated the original post with installation instructions.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Evil_Smiley_za:
You can also download it via Frija and manually update it. Just flash HOME_CSC via odin and it will not wipe the device. If you are on OXM multi CSC firmware just grab the one from DBT and update. If you need help with this I will gladly assist.

I did this to get the update :

Using an Ugreen cable Usb c to usb c and an Windows 11 :

adb reboot recovery

adb devices (to be sure the device is online) because i had to unplug and plug the cable for the phone to be detected

Named the update .bin file to update.zip and moved it to my "adb" folder

adb sideload ./update.zip (Dont know if it change something the "./")

It started with 2% and after 20 min it was done !

Kindly update this info (better everything update to OP)

Prerequisite to flash beta on N20U (N986B)

Dial *#1234#

If your info is ditto same as said below then only you can flash beta 1 for N986B

AP : N986BXXS3DUJ6

CSC : N986BOXM3DUH5

CP : N986BXXS3DUIF

Also if your device is rooted/modified, it will fail. (unlocked bootloader isn't issue but firmware must be complete stock)

Thx, done...but it is still in your quote :)))
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Leon:
So, here are my first thoughts on the new software. I expected more, to be honest. To spot the difference you need to watch some videos on youtube. Material You does not worth the hype, actually the whole update. The animations are very, very bad. I think they work on less than 60Hz or there is fps drop that may explain how bad they are. I hope Samsung will improve the animations and will add something new or at least make it a little bit different from One UI 3. At this point, you can't say if it's 4.0 or 3.0, basically looks the same, but feels much worse. And yes, I understand this is beta.

If anyone wonders if it's worth it or not, I think is not worth trying it.

Good day my friend. Thank you for updating the OP. However I cannot take credit for the info that was posted on the update process.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] KeTuRr74:
For those who are stuck at 60 Hz, you should try to install Galaxy Max Hz wich can force the 120 hz to work, a possible temporary bug fix for this issue ?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jun1662:
I fixed mine by:

- switching the screen resolution from FHD+ to WQHD+, this will disable the 120hz refresh rate,

-then switch back to FHD+

-go to Motion smoothness and click/select adaptive (this did the trick for me)

Hope this helps

For me it's not, but it also happened in the previous beta, Samsung don't sign beta fw. I can live without few months of Google Pay, but worth a warning for other people, it might (and should, because of SafetyNet fail) happen.View attachment 5455819
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] antisocialbratt:
must be a device specific issue. I've been using googlepay since I moved to beta without issues. Even banking apps are working which was a surprise because they did gave me trouble in OneUI3. Then again, it depends on banks. Mine is ICICI so it worked. One of my friend has HDFC account and his app isnt working at all.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
May be dirty flashing beta Gpay and all work but clean flashing may give error. I never used non rooted ROM so pesonally not tested, just a thought.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] KeTuRr74:
Yes that's it doc, dirty flashing the beta and my banking apps with S Pay is working fine (Knox not void)

Knox shouldn't be void while testing original software made by Samsung.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
That is what it is. I dirty flashed the one ui 3 beta and everything worked and then when I did a clean flash it stopped working. That should be the case for one ui 4 Beta.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Evil_Smiley_za:
What do you mean with clean flash? To do a clean flash you need the complete firmware file(s) with AP,BL,CP and CSC. Where dis you get the One UI4 Beta complete firmware file? Or do you mean you factory reset your device after the Beta update? Sorry for my question I am just trying to understand the terminology.

I have just updated to the UI4 Beta and all banking and pay apps work without issue. This Beta actually works very well and could be used on a daily used device. Just my experience so don't hold me to it...:ROFLMAO:

Clean flash mean factory reset, so from recovery (for beta) wipe data/factory reset make a clean flash 😁

Betas are indeed weird. I'm getting pathetic battery life. 4 hours SOT barely.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Evil_Smiley_za:
That makes sense tanx for explaining. I have way too much apps and files on my device to even consider that option. Maybe when final UI4 is out.... Tanx
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Evil_Smiley_za:
Maybe wipe cache because I am also going longer on my battery now with the beta.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] antisocialbratt:
Would that reset my phone or anything? I can't afford to setup the phone all over again from the scratch.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Leon:
Wipe cache won't delete any data from your phone.

Today I received a notification from Google Pay. I will be no longer able to pay with it. That was expected though since the phone is not google play certified. And about the battery life, I think is fine. There is also new option in battery settings, to lock the charging level to 85%.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Anskjer:
Goodlock apps working ?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Leon:
