Lucky you, you PadFone S/X users! There’s a custom ROM based on AOSP code already available for your device to help you install Android 6.0 Marshmallow update right away. It’s CM13 we’re talking about, also known as CyanogenMod 13.
This is unofficial update, and is in no way related to Asus. But it’s still Marshmallow, and feels and runs as Google made it, not tweaked by your OEM.
In our CM13 guide, we told you to expect CM13 ROMs soon, but we didn’t expect Asus PadFone to get it this early. Heck, even popular and developer-oriented devices like Nexus 4 and 5 are yet to grab one.
Anyway, know that you are gonna need TWRP recovery for install CM13, and you will have to unlock your PadFone S/X’s bootloader for this. If you have already done that before, you’re quite ready to install the CM13 ROM and get a Marshmallow update right away.

Warranty may be void of your device if you follow the procedures given on this page. You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.
Backup important files stored on your device before proceeding with the steps below, so that in case something goes wrong you’ll have backup of all your important files.
How to Install
Make sure that the software version of your device is any of these: 22.214.171.124, 126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168 or 22.214.171.124.
If not, then don’t use the guide above. You need to unlock bootloader of your device (as given in guide below), but that has been tested only on above-mentioned software versions. If you try it on any other software version, your device could become dead.
Step 1. Download all the files from above, including the ROM, Gapps, TWRP recovery, script and SuperSU.
Step 2. Create a folder called pad6update and transfer all the files you downloaded into that folder.
Step 3. Rename the twrp file (twrp_126.96.36.199_v4.img ) to an easier one, like pad-twrp.img
Step 4. Connect your Asus PadFone S/X to PC. Transfer these files to your device: ROM, Gapps, SuperSU and script. Remember the files’ location. And disconnect the device from PC now.
Step 5. Boot your Asus PadFone S/X into bootloader mode.
Step 6. Now, open command window in the pad6update folder, in which you have the TWRP recovery file (pad-twrp.img). For this:
- Open the pad6update folder and then left click on empty white space in the folder.
- Now, while holding shift key, right click on empty white space to get a pop-up as shown below.
- Now choose Open command window here option from that.
You will see a command window open up, with location directed to pad6update folder.
Step 7. Run the following commands to boot your device into recovery mode and with TWRP recovery.
fastboot boot pad-twrp.img
You’ll soon see TWRP loaded on your device. It hasn’t been installed btw.
Step 8. [Optional] Once in TWRP, create a backup of your device. Tap on Backup, and then select all the partitions for back. Now do the swipe action at bottom to start creating a backup for emergency cases. This backup is really a lifesaver!
Step 9. Unlock bootloader of your Asus PadFone S/X. For this, you need to flash the unlock script.
For that, on TWRP’s homescreen, tap on Install, and then locate the script file (CrowLock_RC3.zip) and tap on it. Then do the Swipe action at bottom to begin flashing the update. Tap on Home button to go back to homescreen of TWRP.
Step 10. Wipe data of your device now. On TWRP’s homescreen, tap on Wipe, and then do the Swipe action at bottom on next screen to begin flashing the update.
Step 11. Install the Marshmallow update by flashing the CM13 ROM now. On TWRP’s homescreen, tap on Install, and then locate the CM13 file and tap on it. Then do the Swipe action at bottom to begin flashing the update.
Step 12. Install the Gapps file the same way as you installed ROM.
Step 13. To root your device, flash the SuperSU file the same way too.
Step 14. When it’s done, tap on Reboot system button to restart the device.

Tip: Flash TWRP permanently
To install TWRP recovery permanently, after unlocking bootloader that is (not before), use the following command, with device is bootloader mode.
fastboot flash recovery pad-twrp.img
You can safely do this once you have unlocked bootloader of your device. Doing so after installing Marshmallow update is okay, too.
