INSTALL INSTRUCTIONS:
To flash a new ROM properly, you need one of my recoveries (for these I'm sure they works).
*1. Reboot to recovery.
*2. Do a nandroid backup or backup in cwm.
*3. mount USB Mass Storage and delete from sdcard these three directories:
.android_secure
Android
LOSTDIR
4. Copy ROM zip or zips on sdcard
*5. Eject mass storage from computer and then unmount in recovery
*6. wipe all/factory reset or pre-flash wipe in recovery
*7. wipe or erase dalvik cache
*8. flash zip from sdcard, choose ROM zip, flash it and reboot, or if you flash my Max Smart ROM, the phone will reboot itself.
That's all, this is the correct way to flash any new ROM in any phone through recovery.
