For those looking to flash their devices immediately, U1 firmware is now available via Frija and other such tools that pull from Sammy's servers. Manual Entry is required, XAA sales code.

Standard MO for Samsung is to remove the Manual Entry requirement once the official launch date hits. Once that date comes, you should be able to pull it via Automatic.

Someone in the Fold 4 forum verified that current Odin 3.14.x (patched of course) works fine for flashing

Happy flashing!

Thanks! Just successfully flashed this U1 firmware over my AT&T firmware, I did it with the home_csc so all my data is still there.

Does flashing this u1 firmware over u device have negative repercussions? Would the device still get updates as they're released for u1?

How would I go about flashing back to U? everything I've seemingly tried has yielded nothing in Frija.
I'd rather have 5G+ on the ATT firmware/
SamFW.com is great for firmware, but they're not gonna have an AT&T USERDATA file. I'm not sure if everything will work properly without it. I have a source that can get me Samsung firmware for any USA device, but I have to pay him for each one

Flashed
Flashed and was able to enable WiFi-calling with US Mobile that I previously didn't have the option with July update. This is OneUI 4.1.1 btw, and the bottom of the screen is reserved for taskbar which is NOT enabled for Flip 4 so you get a black bar at the bottom in apps, just so you know.

This morning my flip4 finally received the September security patch along with firmware F721U1UEU1AVIA through OTA. My flip4 is an unlocked US phone, I'm on West coast. I haven't noticed any changes yet.

    Does it enable bootloader unlock? I'm not usually a Samsung person but would consider it if this was the case.
    Nope
