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?

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

Do we know why it was an 11.8GB security update though if it wasn't one UI 7.0?

I have no clue

Same here. Takes forever to download. 5 hours and still shows 13%

I wish I could uninstall the update. It took away read receipts and delivery status in text messages. And all the stuff we were able to do with iPhones that were on iOS 18 - now gone. Videos and pics are back to being pixelated and read/delivered receipts has disappeared for that also. The only delivered option is the one in the message settings that sends you a whole notification when the text is delivered. Very annoying.
