There’s always been a way to run GT-i9100 ROMs on AT&T Galaxy S2 SGH-i777 but there’s a really easy way now simply by flashing kernel and modem.

This will work on any GT-i9100 ROMs that are TouchWiz-based and on Android 4.1.2.

Step 1. Download the SGH-i777 modem and Jeboo Kernel:

Download SGH-i777 modem

Download Jeboo Kernel for SGH-i777

Step 2. Also download the GT-i9100 ROM you want to install such as Biftor ROM I am installing in this video tutorial.

Step 3. Reboot into recovery. Then wipe data/factory reset (unless installing same ROM), install ROM, install modem, install Jeboo kernel, and reboot.

That’s it! Huge thanks to XDA developer Jeboo for his Jeboo kernel, which comes with the button fixes and other stuff to make it work out of the box easily.
