Rooting your phone and even trying out new ROMs is part and parcel of being a hardcore enthusiast. Ditching the corporate bloatware from phone network providers — the prime reason for rooting — is tantamount to ditching the corporate advertising and getting your phone back. But community ROMs don’t always match the hype, particularly when it comes to extracting your phone’s full features list.

First things first: Back up everything
Method #1: Nandroid backup
Method #2: Install a new stock ROM
Where to get your ROM
- PDA. This refers to the Android operating system ROM version code, although it doesn’t obliquely refer to Android in any way (just to make it easier… not).
- Phone. What everyone else calls the Radio ROM is Samsung’s Phone ROM, handling the modem and wireless connectivity electronics.
- CSC. This stands for Consumer Software Customisation. It’s a ROM separate to the PDA ROM, which contains the corporate bloatware specific to your network provider and your geographic location.
Picking the right ROM
Beware the bugs
How to get it onto your phone
- Recovery Mode. You copy the ROM file onto your phone’s storage and use the phone’s built-in ‘Recovery Mode’ to install it.
- Samsung Kies. Allow Samsung’s official software to detect the phone and grab the latest official phone/network update and install it.
- Samsung ODIN. Grab the ROM and install it yourself via your PC.

Will a stock ROM keep my phone rooted?
- If the flash process failed, check if it passed the MD5 check test — this checks to see if the download is a valid file. If it failed, download it again.
- If the MD5 checksum test is fine, try flashing it again.
