[Discontinued] CyanogenMod 12.1 (Android 5.1) for Samsung Galaxy Express AT&T (SGH-I437)

This is a mobile optimized version of this page, view original page.
This project has been discontinued!

I’m not going to develop this ROM any more. It takes too much time, and my phone is about to die, which means I’ll be getting a new one. Also, Android 5+ runs too slowly on this hardware. That’s why I’m currently using CyanogenMod 11 (which is back up at download.cyanogenmod.org). I advise you do the same. All changes I made are available on my GitHub.

I finally managed to build CyanogenMod 12.1 for the Galaxy Express! Yayy!

(the header image is still the old one, it hasn’t been updated with the new screenshots)

But it has bugs! Beware! Make sure you have back-ups!

If you’re looking for something more usable, try CyanogenMod 12. Also, make sure you read all the warnings and notices. It’s highly experimental.

Known bugs

Not tested

What works


This is for testing only! I take no responsibility for damages that can occur to your device! Make sure you read the old CyanogenMod 12 post before continuing!

Warning! The latest build hasn’t been tested. It may have more bugs or it may not. Try it and let me know. I have no time to test it.

Please test and let me know what works for you through the contact form.

I’ll try to fix what’s not working. If you think you can help, please let me know!!!
