Here's what I noticed on XAA they prioritize TDD bands than CA like mine.
I enabled only 3, 7, and 20 bands which is needed, but aggregation not work they work separateHere's what I noticed on XAA they prioritize TDD bands than CA like mine.
In my place band 3 and 28 are aggregated but my phone connects to TDD band 41 most of the time.
And I don't mind this since it's faster in the morning and night but CA on early morning (1AM) is faster.
Try this check what band you're connected now using *#0011#
Mine is band 41

Then disable the band on the Band Selection menu. Then check your data indicator if it becomes 4G+ or LTE+.

Do it again on the band currently connected if still not on CA.
If you confirmed that there's a CA on your location and you've done all the setup here.
Check out this thread for info on s22 and also most works for the s20 and .note as.well!
Nope it's the september security patch
How did you downgrade and what did you downgrade to in order to get the extra 5G bands? I was reading back and I found this post if you can enable n25 then I should be able to enable n25 on my ultra as well but I'm afraid I'm already on Android 12 so I bet the downgrade to Android 11 probably won't be possible.If someone planning to downgrade just to get the band you want to activate on Samsung Note 20 Ultra 5G US unlocked SM-N986U1
Here's the result:

It only unlocks band n2 n12 n25 n66 and all available bands in SA.
The thread that I posted with the IMEI simulation tactic or option only unlocks the bands that are FCC verified for your phone so basically if you go ahead and do that and change that to GCF you will open up all 5G bands that are supposed to be enabled for your device not anything more not anything extra so when I'm on the T-Mobile SIM and the T-Mobile CSC I only get the T-Mobile bands available but when I go to GCF it unlocks all the 5G bands for every carrier that this phone is enabled for and since it's a US version it's the 256671-41 and so on but I seen in the earlier post that you were able to unlock in 25 and such and 25 will help me because I know T-Mobile is using n25 for their Network.Nope it's the september security patch
Btw the thread you provided doesn't unlock any other bands like n78 on U1 note 20 ultra since removing SA permit list and setting lte band config do this results too.

It doesn't affect the NR combination too.
I need the b3+n41 combo but the firmware only supports b41+n41.

I just warned users since there's a fix by downgrading when you messed up something on nv files. (Efs explorer)How did you downgrade and what did you downgrade to in order to get the extra 5G bands?

I have also heard there was a beta for Android 11 that was released that did indeed unlock most of the 5G bands and they quickly remedied it with a fix but I'm sure the beta is still rolling around out there somewhere or available.
I'm also trying to update to the 13:beta as we speak but I'm having trouble finding the file for the s20 ultraI just warned users since there's a fix by downgrading when you messed up something on nv files. (Efs explorer)
Downgrading also is the only way to access the service menu before the other trick has been discovered (samfw tool).
If the android 11 beta to unlock other bands is real then they should never update the firmware with bootloader 3.
On my end I don't need to unlock other bands since n41 is the only available 5G band on my location and it is already available on my device.
The ENDC combination is my only problem that is encoded on the firmware and can't be modified.
I'm looking forward for the android 13 oneui5 if some miracle will happen lol.
Did it enable n78 on S20+ ?
Following code works to bring up CSC menu.
Hi, mellojosh. Great thread. Unfortunately the screen grabs you had in post #25 all disappeared during the forum migration. If there is any way that you can replace them that would be epic. Thanks.
