I had the same today, no internet around town, but we were having a thunderstorm and i initially thought it might be that. I flashed first 4 betas wit DBT and beta 5 with BTU, i was waiting at the service centre near home and decided to try downloading DBT and reflashing, file downloaded in like 90 seconds.
Can someone correct me if i'm wrong please:
I'm currently on Beta 1 for the S20+ 5G/DS (SM-G986B) on the OXM CSC (I just installed the update.zip without changing CSC)
As there is no Beta 2 available, in order to get all updates (after clicking on the Samsung Members app link in one of the posts), do I need to install the DBT Android 10 ROM in it's entirety (while using the normal non-HOME CSC so it wipes the phone and changes CSC), or is there another way around getting the updates?
You can flash BTIJ (with HOME_CSC if you don't want to wipe your phone's memory), then BTU (UK Beta) Beta 1 BTIJ -> ZTJF, then DBT (German Beta) Beta 3 ZTJF -> ZTJN all the way to Beta 5. As long as you're following version numbers, even if they're not coming from the same country, you'll be fine (it's the very same binary).
However; i'm currently already on ZTJA (DBT BETA 1), so when i try to install the UK BETA 1 (BTIJ-ZTJF) over this, it fails and aborts. Is the only way around this to flash back to an Android 10 Stock ROM and then run through the updates?
Will I end up losing my data if I flash the HOME_CSC while downgrading from Android 11 > Android 10 ?
Thank you for your help though dude
You can still downgrade and not boot into BTIJ.
I was on beta1, and what I did to flash beta2 is:
reboot in bootloader
flash BTIJ (with HOME_CSC to keep data)
after the phone restarted and displayed the "Erasing" message (which doesn't erase data), I quickly pressed Vol Up + Power to enter recovery mode (still possible on BTIJ)
In recovery, formatted cache and sideloaded the beta2 update.zip
reboot and serve cold
Yesterday i had an internet problem, seemed to be after i had enabled wifi calling.
Today i enabled wifi calling and again i now cant get mobile or wifi data on some apps. Google and Samsung weather are ok but Google maps, YouTube vanced, playstore, Facebook...nothing.
Cleared cache from recovery and reboot twice.
you are absolutely rightmaybe you could try flashing CP (which contains modem partition) from latest beta to see if that works together with final ROM and narrow down if the problem is related to modem firmware or kernel drivers... also older CSC that contains carrier settings could help.
but please beware, that these mixed versions could not work together so do that at your own risk.
thanks that really helped.
go to settings > apps and select google play services, then 3dot menu > uninstall updates
