Here's how I updated to 4.4.4. This applies to anyone using Windows. I was on stock 4.4.3 with Xposed, ElementalX kernel and rooted via SuperSU. This will not wipe your data and, if you use Xposed, all of your settings for your modules will be preserved.
Make sure you have done the following before you update using the factory image:
1. Uninstall Xposed Framework but don't uninstall your modules.
2. Choose the Full Unroot option in the SuperSU app.
3. It might also be a good idea to flash the stock kernel if you're using a custom kernel. You can find the stock kernels for 4.4, 4.4.1, 4.4.2 and 4.4.3
here. Use the one for 4.4.3 and flash it in recovery.
After doing these steps, reboot into the bootloader. On Windows, extract the factory image folder named "hammerhead-ktu84p" which contains:
bootloader-hammerhead-hhz11k.img
flash-all.bat
flash-all.sh
flash-base.sh
image-hammerhead-ktu84p.zip
radio-hammerhead-m8974a-2.0.50.1.16.img
Open the file named "flash-all.bat" in a file editor in Windows, I prefer Notepad++. Look for the line,
Code:
fastboot -w update image-hammerhead-ktu84p.zip
and remove the "-w" then save the file. This W flag is what wipes your data. That's what we don't want.
Now, provided you have your adb/fastboot environment set up, run:
then
This will install the factory image without using the -W flag. Let it complete, your phone will reboot and you'll be on 4.4.4! Now just flash your recovery of choice (I use TWRP), install SuperSU, install Xposed Framework and you're done!
