Install CM11 M9 Custom ROM on HTC One M8
- HTC One 2014 edition (M8) – it is not recommended for any other device!
- A USB cable and latest HTC USB drivers installed on PC
- Custom recovery like TWRP or CWM with root access on phone
- Phone’s bootloader should be unlocked (visit this page)
- At least 60% of remaining battery
- Full backup of existing data present in phone’s internal memory. I’d recommend you to create Nandroid backup using CWM recovery as it creates a complete image of current OS.
Disclaimer: Even though this ROM has been fully tested on HTC One M8 and it is a stable (snapshot) build, neither we nor the developers shall be held liable for any kind of data loss or device malfunctions during or after the upgrade. You warranty will be lost and you’ll have to pay HTC to get your bricked device repaired. Therefore, proceed at your own risk!
2. Upgrade Procedure
1. Download CM11 M9 custom ROM and Google apps on your PC using the aforementioned download links.
2. Connect your One M8 to the PC as a mass storage device.
3. Copy “cm-11-20140804-SNAPSHOT-M9-m8.zip” and “gapps-kk-20140606-signed.zip” to the root directory of your phone’s SD card i.e. they shouldn’t be placed inside any folder.
4. After that, disconnect the USB and power cord and turn off your phone.
5. Now open the Bootloader mode by holding Volume Down + Power Button for 8-10 seconds until a menu appears on the screen. Select “Recovery” to enter the custom recovery mode.
6. Once you’ve opened the Custom Recovery (I’ll be using ClockworkMod recovery here), select “wipe data/factory reset” and “wipe cache partition” options to wipe out the current system.
7. Go to advanced > wipe dalvik cache to clear current app data. This step is highly recommended if you don’t want to get stuck in unwanted bootloops after flashing this ROM.
8. Next, return to the main menu. Select “install zip from SD card” option and choose “cm-11-20140804-SNAPSHOT-M9-m8.zip” file. It’ll take up to 5 minutes to complete.
9. If you want to install Google apps (Google+, Gmail, Play, Maps, etc.) on this new ROM, again select “install zip from SD card” option and choose “gapps-kk-20140606-signed.zip” to reflash the Gapps.
10. Upon completion, reboot your phone normally enjoy the new CyanogenMod 11 M9!
