How to Flash a ROM Properly?

I recommend the following procedures because it is safe and recommended by CyanogenMod and also I recommend the users of Clockworkmod Recovery v5.0.2.7, to update for v6.0.3.1 which is Pretty Good & Working Perfectly.

How to Flash a ROM Properly using Clockworkmod Recovery v6.0.3.1 ?

For Clockworkmod Recovery v6.0.2.9, DarkSide Super Wipe & DarkSide Cache Wipe Zips are not necessary

Reboot to Clockworkmod Recovery

1. Backup Current ROM.

2. Go to Wipe data/factory reset, then Do a Wipe Cache.

3. Go to Mounts and Storage, then Format /system -> Format /data & Format /cache.

4. Go to Advanced, then Do a Wipe dalvik cache.

5. Install the ROM Zip from the SD Card or Internal Memory & then Install New GApps for CM10.1.

6. Reboot and Let the ROM settle for 5-10 minutes.

Note: Restore apps without data if your are using any backup tools such as TitaniumBackup etc., Restoring Apps with data cause Problems

How to Update ROM Properly?

After Installing CM10.1, If you want to update to new Nightly or Stable, a full wipe is not required.

We can do a Dirty Flash as Follows. This will not erase data & its Safe.

1. Reboot to Clockworkmod Recovery

2. Do a Wipe cache partition

3. Go to Advanced, then Do a Wipe dalvik cache

4. Install the ROM Zip from the SD Card or Internal Memory & Reboot.

That's it.

In order to use Greenify without Root Errors, Install SuperSU (better than SuperUser) from Play Store. Give SuperSU root permissions. You can keep both SuperUser and SuperSU in your device. After installing SuperSU, now it takes charge from SuperUser. Don't delete SuperUser. Just keep it. It comes with CM. Now Install Greenify. Give the Root Permissions to it.
