Supported Devices

• Motorola Nexus 6 (shamu)

Version History

• v1 - Initial version with HTC Nexus 9 WiFi (flounder) support
  


• v2 - Added Motorola Nexus 6 (shamu) support
  


• v3 - Added support for HTC Nexus 9 LTE (flounder_lte)
  


• v4 - Added support for signed boot-images
  


• v5 - Changed error handling to compensate for missing fstab files. Some roms seem not to ship with the complete set of boot-files from AOSP.
  


• v6 - FED-Patcher will enforce the same structure for the patched boot.img that the original boot.img had. Additionally, the kernel commandline will also be taken over. This should fix pretty much every case where devices would not boot after patching.
  


• v7 - FED-Patcher will now disable dm-verity in fstab to get rid of the red error sign on marshmallow roms.

What Do I need To Make This Work?

• A supported device (Your nexus 6)
  


• An unlocked bootloader
  


• An already installed ROM with forceencrypt flag. (like cyanogenmod CM12.1)
  


• A recovery that includes busybox (TWRP, CWM)

How Do I Use it?

• Follow Instructions above - This is the basic need to know information
  


• Make a thorough, conservative backup of your data if there is any on your device
  


• Go into your recovery (TWRP, CWM)
  


• Flash fed_patcher-signed.zip
  


• If your device is already encrypted (You booted your ROM at least once) you need to do a full wipe to get rid of the encryption. This full wipe will clear all your data on your data-partition (where your apps as well as their settings are stored) as well as on your internal storage so please, do a backup before. If you don't do a backup and want to restore your data... well... Call obama.

IMPORTANT: If you update your ROM you have to run FED-Patcher again because ROM-updates also update the boot-partition which effectively removes my patch. So, if you are on CM12.1 for example and you used my patch and do an update to a newer nightly you have to run FED-Patcher again. If you don't do so Android will encrypt your device at the first boot.

Is It Dangerous?
Well, I implemented tons of checks that prevent pretty much anything bad from happening. But, of course, we're dealing with the boot-partition here. Even though I tested FED-Patcher quite a lot there is still room for crap hitting the fan.
