- Download and install adb
- Download the CyanogenMod build package and optional 3rd party packages (such as Goole Apps)
- Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard
- You may do this by copying the files in the running Android system or
- Boot into recovery mode (Vol UP & Home & Power) and use adb.
adb push filename.zip /sdcard/
- Enter Recovery mode if not already
- Optional (Recommended): Select the Backup button to create a backup.
- Select Wipe and then Factory Reset.
- Select Install (if you're running CyanogenMod Recovery this is 'Apply Update').
- Navigate to
/sdcardand select the CyanogenMod .zip package. - Follow the on-screen notices to install the package.
- Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
- Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.
You can download and flash TWRP (TeamWin Recovery) via Rasher (Recovery tools) or TWRP manger. Both apps can be installed from the Google Play Store.
I'm not sure if the jfltexx ClockWorkMod recovery will work but I've heard it may not, so I'd just flash TWRP (I prefer it anyways, much nicer UI.)
You can still flash it if you have ClockWorkMod, it will just replace your recovery with TWRP.
If you want CM12 official, you can use the jfltexx ROM zip. Just make sure to flash team win recovery jfltexx 2.8.4.0 (2.8.5.0 did not work at all for me.) You just need to match the recovery variant with the ROM varient. Flashing the jfltexx recovery and using the jfltexx CM12 did not brick my jfltecan (I337M) phone or cause any problems. Works perfect.
