Evita Custom ROMs - bibanon/android-development-codex GitHub Wiki

When the HTCDev unlock is used, the phone will remain S-ON. This means that you'll need to manually flash boot.img from a computer every time you change ROMs.

{{Note|If you're updating to a newer version of the same ROM, you generally don't need to flash boot.img; but this is not a guarantee.}}

After installing a custom ROM, your phone might not boot. If it doesn't, you'll need to manually flash boot.img from a computer.

1. Open up your custom recovery's zip archive and extract a file called boot.img . Move that file to the folder where the fastboot program is stored.

2. Turn off the phone and hold {{Key|Power}} + {{Key|Volume Down}} to enter bootloader mode.

3. Select fastboot from the menu.

4. Run this command from your computer.

   fastboot flash boot boot.img

5. Reboot your phone.

   fastboot reboot
