Thanks! Running great so far
Was on SlimBean ROM but just did this process this morning. Since this process starts you from stock unrooted GB27, I first used the official Samsung update tool (SimpleDownloader) to reflash the phone back to bone stock GB27. Had to do it twice...first time, I flashed to GB27, it would boot loop to the 4G screen. Reflashed it again and stock GB27 was working just fine.
When I flashed this, I used FI27 modem not FL24 (as initially indicated in first post). Upon first boot into CM11, I was getting a lot of "...process.android..." errors, but after rebooting a couple times, linking up to WiFi, and letting it go through the "Android is updating" process, it all seemed to work itself out.
Have only had it on a couple hours on this ROM so, but the basic functions "seem" to be working: hooks to wifi, internet works, cameras work (well, just turned them on to see if they would turn on), messaging app opens, phone app opens, file manager, settings, etc. Need to check GPS since some have posted that might be working correctly. However, I'm only using this as a game/web-surfing/music player device, so I probably wont check if phone or messaging or cellular data is actually working. Otherwise, seems to be doing fine.
Thanks to the op for posting this process, and all those others that built/provided the various files necessary!
