Install CM for jflteatt
Modifying or replacing your device's software may void your device's warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.
This guide is for advanced users and does not come with support. It is provided as a means to install CyanogenMod. A working adb connection as well as adb being in your PATH is required for this guide and users should not proceed without this. Additionally, you must be on build I337UCUAMDB or I337UCUAMDL or this will not work. In fact, if you try to use this method on a newer revision, you will almost certainly brick your device. Seriously don't try it. Downgrading won't work either. If you've updated, a qfuse is already tripped and any attempt to downgrade will also result in a brick.

adb push filename.zip /sdcard/
- Note: You can copy the
.zippackages to your device using any method you are familiar with. The
adbmethod is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure
/sdcard(sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
