What is the CSC of this update? I have eSIM setup and I don't want to lose it. Can anyone please confirm the CSC, eSIM and SamsungPay working? Mine is in XSA (Unlocked Australia Ultra)
CSC is OXM:

Code:

XSA is part of it. You should be safe to install it.
Unless specific error messages, you should be able to do it...and yes, you are officially registered for enrollment, so you'll receive newer builds.
Actually, no. Even last year, if you installed the beta manually, you lost the ability to enter the beta program itself - Members enters this franken-state of having the beta installed (thus the enrollment pop-up is disabled), but not being signed up for the beta.

Last year there was a thread of Samsung Members deeplinks that allowed users to get to the specific sign-up pages, through which one could manage to sign up, but last year the beta was also limited in numbers - IIRC only 10.000 people per region were allowed. This might change this year as I saw no sign of any limit mentioned on the already running beta programs (Korea, US, Germany).

Nonetheless, I doubt the beta sign-up banner will appear in Members if you're already running the beta. My recommendation is, wait for the deeplink collection, and try to sign up through that.

Meh...thought to a better behaviour from Samsung.

Thanks to explanation however.

you need to be on latest update!! G998BXXS3AUHD/G998BOXM3AUHB/G998BXXU3AUHB in order to get te update.zip to install

and u have to use official recovery too :)
AUHB isn't enough, I think - you'd need AUHD.

EDIT: Yup, just checked, according to the build info, you need to be on these precise versions for the four images:


Code:
source_ap_file=AP_G998BXXS3AUHD_CL22360073_QB42598884_REV01_user_low_ship_MULTI_CERT_meta_OS11.tar.md5
source_bl_file=BL_G998BXXS3AUHD_CL22360073_QB42598884_REV01_user_low_ship_MULTI_CERT.tar.md5
source_cp_file=CP_G998BXXU3AUHB_CP20059105_CL22360073_QB42515811_REV01_user_low_ship_MULTI_CERT.tar.md5
source_csc_file=CSC_OMC_OXM_G998BOXM3AUHB_CL22360073_QB42515811_REV01_user_low_ship_MULTI_CERT.tar.md5

So to clarify:

AP: G998BXXS3AUHD
BL: G998BXXS3AUHD
CP: G998BXXU3AUHB
CSC: G998BOXM3AUHB

Code:
current_version=G998BXXS3AUHD/G998BOXM3AUHB/G998BXXU3AUHB
updated_version=G998BXXU3ZUID/G998BOXM3ZUID/G998BXXU3ZUIC

If you're wondering where I got this... Open up the OTA zip, and look for the file `build_info.txt` - it has all the necessary data in there.
