Hello Guys! As of now many of you have rooted your Android phone & many of you have flashed Custom ROMs in it. But many of you don’t know how to flash a ROM in a correct way. A ROM needs a perfect & clean installation. If you will not do that you can get issues, sometimes very serious issues.

What is a Clean Installation?
A clean installation stands for everything wiped before flashing the ROM.

Why ROM needs a clean installation?
A ROM needs a clean installation because if you will not do it the two ROMs ( One which is already installed & second which you have flashed) will conflict each other. And will give you different issues.

What issues I can get after a dirty install?
If you flash a ROM in a dirty way than you can get various issues:-
• Unknown Baseband
• Invalid IMEI
• NVRAM Error
• Unknown MAC Address
• Minor or Major Lags
• Freezes during use of phone
• Performance & Battery issues
• App force stop issues
• Auto Reboot issues
• Bootloops

Note:- These issues can be found also when you have done a clean installation. It is due to the ROM Bugs.

Which method we usually does while flashing the ROM?
•Go to Recovery

•Choose Zip from SD Card
•Select zip & flash
