[T-Mobile Samsung Galaxy S 4] piotreks4:
I've tried the latest nightly[1], but here is the path I'd recommend (a little complicated, so feel free to adjust based on your experience -- I was able to do all of the steps with the phone connected via USB, once in TWRP, the sd card is freely accessible):

*** If you have any important data on your phone, BACK IT UP NOW, as the steps below will ZAPPPP everything ***

0) I am going to assume you have a recovery of some sort installed, if it's not TWRP, I recommend you upgrade to TWRP, as follows:

0.1) Get the TWRP-3.0.0-F2FS(JDC).zip file from Creeper36's post[0] (don't forget to thank him)

0.2) Put the zip on your sd card

0.3) Boot into recovery

0.4) Install the TWRP zip from sd card

0.5) Reboot into recovery.

1) Download the CM11 stable snapshot[2] and put it on your sd card

2) Download the "20140606 on AFH" Google Apps from here[3]. These apps are 'stock' (most of Google apps). I don't like Google that much, so I also downloaded the 'nano' version of OpenGApps. Put the zip(s) on your sd card.

3) Download the latest CM11 nightly[1]

4) Follow these steps from Creeper36's directions:

= 'WIPE' > 'ADVANCED WIPE' > Tick (enable): Dalvik/ART Cache, Cache, Data, Internal Storage, Preload, and System.

= SWIPE TO WIPE

= Go back one menu then 'FORMAT DATA' - type 'YES' and press blue checkmark.

= Go back to Main Menu

5) Follow these steps from Creeper36's diections:

= Install new ROM by Clicking 'INSTALL' > Find your CM11 SNAPSHOT ROM you downloaded. -- make sure you 'Select Storage' (near the bottom) > 'Micro SDCard' > 'OK'.. then SWIPE to Install.

= Install GApps by Clicking 'INSTALL' > Find your 'KK SIGNED GApps' you downloaded.. then SWIPE to Install.

= 'Wipe Cache and Dalvik'.

= 'REBOOT' into system. (Your System is now successfully Installed!)

6) Go through initial setup on your phone (set up your gmail account, etc, but don't download any additional apps, just the basics).

7) Reboot into TWRP recovery.

8) Follow these steps from Creeper36's diections:

= Install new ROM by Clicking 'INSTALL' > Find your CM11 NIGHTLY ROM you downloaded. -- make sure you 'Select Storage' (near the bottom) > 'Micro SDCard' > 'OK'.. then SWIPE to Install.

*** OPTIONAL: I only did this because I don't like Google bloat on my phone: ***

= Install GApps by Clicking 'INSTALL' > Find your 'NANO GApps' you downloaded.. then SWIPE to Install.

*** END OPTIONAL section ***

= 'Wipe Cache and Dalvik'.

= 'REBOOT' into system. (Your System is now successfully Installed!)

9) At this point I got a single "your app is not responding message" for the UI, but it never came back. I assume it's because I replaced GApps with a smaller version (missing components) and once the runtime reloaded the corresponding objects, everything was/is fine.

As of right now, the phone is working as expected, Skype, Google Voice, telephone, network, camera -- all seem to be fine.

I have not tested GPS, BT, IR or NFC.

Hope this helps (don't forget to thank Creeper36 for his/her awesome directions!!!)

Cheers!
