Remember
================
- Collect the right Custom Recovery, there are may flavours (TWRP/CWM/CTR), it doesnt matter. The Important things is that collect the appropriate TWRP/CWM/CTR which one is ported for your Device.
- Collect the right ROM that is ported for your device
- Before Installing new ROM, always keep a backup
- Before installing rom do a wipe (Factory reset/Wipe Data/System/Cache)
- After flashing rom if it wont boot keep patience and wait for 5 min. If it still won't boot go to the Recovery Mode again and Restore your original ROM from backup
- Do it at your own risk. I am not responsible for any damage
