samsung galaxy s4

 AT&T would not typically have updates that are 7 or 8 years old on their servers anymore. And if you're not using the phone on at&t, the update would never be triggered.

i got it to work on a sim once but it crashed on the screen and i had to reinstall android 4.4.4 so i think it got a corrupted file

Hi Noor8706! There hasn't been a new software update for the Samsung Galaxy S4 in several years.

Also, as @formerlyknownas already shared, software updates on our website are only available for AT&T branded devices. Keep in mind:

• The update may not work if you brought your own device to AT&T.
• You can check with the original carrier or manufacturer for software updates.

However, if you're an AT&T customer, then you will want to take the steps to upgrade your device as recommended under We can help upgrade your AT&T Wireless device or Get help upgrading your AT&T PREPAID device (depending on the wireless service for your AT&T account) when you visit Get details on the 3G network shut down.

On February 22nd, 2022, AT&T shut down the 3G network. This enables our network to better accommodate next generation technologies and services.

Customers using unsupported devices will need to upgrade to an HD Voice capable device, upgrade their SIM, or both. Under Device that still work, you can view our list of supported device by clicking Find out if your device still works on our network.

We hope this information helps. Thank you for reaching out to AT&T Community Forums.

Thank you for sharing those details, Noor8706!

If you're not currently with a cellphone wireless carrier, then you will need to subscribe to one in order to receive a software update for your phone.

However, as already shared in previous replies, AT&T no longer provides software updates for the Samsung Galaxy S4.

Thank you for contacting AT&T Community Forums.

Please refer to my first post

And if you're not using the phone on at&t, the update would never be triggered.

AT&T phones do not update unless they are connected to AT&T.  Which means you have to be in the United States and using an AT&T SIM card.

In your case, it's not going to matter. AT&T will not have an update that old on a server anymore. Unless you can handle this on your own through other means, which is not a permitted discussion on this forum, your phone is going to stay on Android 4.
