N986USQU2DUC5...wat firmware should I flash from u1...thanks guys been a awhile just came home from doing 5...so trying to catch up things have changed...
Sounds like you are trying to flash to a u1 firmware. If that is the case you are currently on a bootloader v2 firmware, which means you will need to stay with a u1 firmware with that as well.

In the 3rd post can see where the bootloader v2 started, so can flash anything from that point and newer.

Hello all,

I'm currently running N986USQS1CTLC on my unlocked Note20 Ultra. Is there any issues with upgrading to N986USQU2DUC5? I understand that I will be going from a v1 BL to a v2 and there's no turning back to a v1 BL so I want to be sure.

Also, can I do a dirty update or will I need to do a clean?

There should be no issues for you to go to the latest. I would absolutely do a clean install though

Thanks for the quick reply.....
I've seen in some recent posts about the U1 v2 BL firmware experiencing constant phone crashes/restarts when opening camera? Do you know if this issues is happening in the N986USQU2DUC5 firmware?

You're welcome
I think it might have been on the U firmware. I'm now on U1 and am not having any of those issues

"Sort of"
If your device is currently on a bootloader 2 firmware, you can not flash a bootloader 1 firmware. Aside from that, it doesn't matter. Typically I'd recommend flashing the most current one. It'll have the latest security patches.

Edit** BTW the top most ones are the latest

Reading a post from warriorvibhu (post #1,687) he says the camera crashes is happening to him and he's always have been on U1. Then again I also see your response about before going to U1 you were experiencing the camera crashes. So it's happening on U and U1? Thinking I might hold off for a little while to see if the camera issue gets sorted out before going through the effort of a clean install.

The phone that I would be flashing is my work phone so when I do a wipe breaks my corporate Multi-factor authentication (MFA) connectivity and MDM certs which requires me to engage IT to manually reset my MFA account / MDM certs as it some how detected that I wiped my phone. Anyway it's a lot more effort then the norm.
