5.Do not turn off Computer during Updating Process:
This mistake has same effects as having low battery on your device. That is why be careful to keep your computer plugged in during whole process.
6.Backup all your important Data:
Normally, rooting process does not wipe out your data but to be on the safe side, it is advisable to backup your data so that you can recover it in case of data wipe. If you are using a SD Card, remove it before rooting and insert it again after rooting has been done. Backup all data on internal storage on your computer. Backup messages and contacts by using methods described above. Follow this BACKUP GUIDE. If your device is rooted, BACKUP DATA WITH TITANIUM BACKUP.
If you already have TWRP or CWM recovery on your device, then you should make a Nandroid Backup. In case something goes wrong or you don’t like new update, you can easily go back to previous ROM easily.
6.Be careful to use correct file for updating:
Sometimes we have lots of files, having similar names put together in same folder. Accidently, we can use a wrong file which can result in bricking device. Therefore, it is advisable to put specific files for your device in a separate folder. This way, you will not be mistaken.
