So, you want to install a new custom ROM on your newly rooted HTC Evo 4G LTE?
Well, before you do anything else, we HIGHLY RECOMMEND you to make a backup of your ROM. Backing up ROM will backup your whole ROM, kernel, personal settings, and even apps. It backs up everything except for contents of your internal storage and microSD card such as personal photos and videos.
It only takes 10 minutes so once you unlock your bootloader and install TWRP recovery, make a backup right away. That way, you can always restore your ROM when you need to easily.
Step 1. Reboot into bootloader by holding down Volume Down and Power buttons together for 10 seconds.
Step 2. When your phone reboots, let go of the Power button for a second then hold it down again.
Step 3. Choose “RECOVERY” and hit the Power button.
Step 4. Once in TWRP recovery, choose “Backup”.
Step 5. Swipe to start backing up, that’s it!
Step 6. When your backup is done, make sure there’s no errors like below.
Step 7. To restore your ROM, simply choose “Restore” from main menu in TWRP recovery.
Step 8. You will have the option to choose a backup folder. All backups are stored in a folder under TWRP in your internal storage with date and time. You can always change the name of these folder to something more memorable.
By using backup and restore feature on the TWRP recovery, you can have multiple backups of various different custom ROMs you try. This way, you can run multiple ROMs on the go and also a great way to restore your phone when something goes wrong.
