I bought my S22 from AT&T and had AT&T service. For a while, I had an AT&T physical sim and a Verizon esim. I noticed everytime I made AT&T my primary sim and restarted, the AT&T splash screen would display and all of the AT&T bloatware would install and be uninstallable. As soon as I switch to the verizon esim, the at&t bloatware I could uninstall and all of verizon's bloatware would install. Before this, I thought there was an AT&T specific S22 and a Verizon specific S22. But, with this test, I realized an S22 is an S22 no matter if it's from Verizon, AT&T, Boost mobile, etc. The hardware is identical. (I was thinking maybe the radio to talk to the towers were specific before.)
So, with this new knowledge, I switched completely to Verizon cancelling AT&T. I was having some issues, so I went to a verizon store. They deleted the Verizon esim and put a physical sim in. It's been working good. But, some Verizon services I still can't use. For instance, I cannot use verizon's spam caller filter service. It will not work. I'm told because I have an AT&T phone is the reason why. So, I'm thinking in my mind, probably my theory is close, but maybe the hardware is identical but the firmware is different. Maybe I need to flash verizon's firmware to make it identical to if I bought it from a verizon store instead. So, I went to sammmobile and downloaded the latest verizon specific s22 firmware. I'm trying to flash it with odin... it's not working. Everytime I attempt to flash it with odin, it fails on the auth step. I'm wondering if it's because the bootloader is not unlocked? I enabled developer mode and usb debugging. I'm not trying to root it or unlock the bootloader. Just flash the verizon stock firmware. Is there another setting I need to enable to allow me to flash it? Or what am I missing?
