* Your warranty is now void.
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
Wipe data, cache, and dalvik
Install Rom zip file
Flash modem (if needed)
Flash kernel (if needed)
Boot into rom. You will likely have working 3g and not 4g. Setup the rom all the way through until you get to the homescreen.
Enable root using the permissions app in the security folder.
Add att apn
Download Terminal Emulator from play store
Type su. Hit enter. Type "fixdata.sh" without the quotes. The device will reboot
Apply a new MIUI theme to fix voice calling and reboot
Google apps are now flashed seperately. Use 20121011 release.
ROOT: root works with my build.prop. Open the permissions app in the security center, and enable root.
If you accidentally go into mobile networks, just run "fixdata.sh" from terminal again*Not sure if this applies to us on ATT, because i had to go set up the ATT APN and save it..
MIUI 3.12.20 adapted to att
Touchwiz based (keep multiwindow and s-pen functions)
A few force closes when you boot up but after that very smooth.
DO NOT GO INTO MOBILE NETWORK SCREEN OR YOU WILL LOSE LTE. THIS DOESN'T JUST MEAN DON'T CHANGE ANYTHING. Don't tap mobile networks AT ALL. If you do this, you will have to run fixdata.sh again
MIUI 3.12.20 ROM
I recommend using saber kernel from HERE
KNOWN ISSUES AS OF NOW:
Phone.apk crashes a few times at bootup (turn off show force closes if you don't want to see it)
3G/1X always shows no signal regardless of actual strength
Stock theme causes Phone.apk to crash when making a call ---- switch to a different theme and reboot to fix
