[ROM][PORT] MIUIv3 2.4.20 (Bieltv.3's CM7 RC4 based) (10/3/2014)

What's not working:

USB tethering
FM Radio (Not tested)
HW (Partially)

Installation Guide:

(RECOMMENDED) Be on a stock ROM, installation will be cleaner
Download THIS EXT4 tool, the Kernel and the Rom on your device.
Flash on Samsung recovery (or your recovery if you are not on stock), my temp. CWM.
When you are on the Temp. CWM, flash the EXT4 Formatter tool, so whole system will be converted to EXT4. (Stock filesystem is RFS)
After the installation, flash my kernel you have downloaded before.
When the Kernel is installed, go, on the CWM, to advanced --> reboot recovery (this will reboot the device, and turn it on on the new CWM of kernel)
Wipe data, cache and dalvik
(IMPORTANT) Go to mounts and storage, and make sure system is mounted (will show unmounted) mount it 2 times!
Go to install zip from SD Card, choose zip from SD card and install your MIUIv3. (MAKE SURE installation last more than 5 seconds, if is less than 5 secodns, your system is unmounted! repeate step 8).
Mount the System again and install GApps.
After installation, go back and reboot system, if you made it good, ROM boots, so no problem on it.
