Failed January Update

[userq3DRoBDJRw]

Trying to update my S23 Ultra with the most recent update but it keeps failing. I have a locked Verizon phone. Everytime I try to update, it's super slow and eventually fails giving my "Error Code: 407". I tried clearing cache, clearing data, restarting my phone, using Smart Switch, switching between wifi and data, switching between different wifi networks. I have enough space on my phone (300gb free). If I knew what the error code meant, I could diagnose further. Google hasn't been helpful. Samsung support hasn't been helpful. They are telling me to manually flash my device but I wanna leave that as a last resort. Any suggestions?

Could be that not sure

Then why would all our phones say 15 and keeps trying to download? Hmmm

I did the partition cache reset. Still cant get the download to complete.

it 's not android 15, it's security update 15.

I'm having the same issue with my S24 Ultra. The download is very slow and it never completes but gives me a failed error 407

I had the same issue yesterday. Today it seems to be working but is super slow. Has been updating all morning and is at 45%.

I am trying to update my s24 to the security update 15, and it has failed 4 times and is now installing but taking very long. It's been 4 hours and it's it 26%. I have very fast internet,tons of storage still and I don't know why.

Cancel the installation of the new update and reset the phone
