INSTRUCTIONS:
- First time flashing CM 7 to your Desire (or coming from another ROM)?
1. Root your device and install Clockwork Recovery (Unrevoked method is recommended).
2. Do a Nandroid backup!
3. Update your radio! New radio from HTC 2.2+ roms is required (Desire Radio Thread).
4. WIPE (wipe data/factory reset + wipe cache partition)
5. Install the ROM
6. Optionally install the Google Addon
- Upgrading from earlier CM6?
1. Do a Nandroid Backup!
2. Install the ROM (your Google apps will be backed up automatically)
