(Manually) Flashing Updates
Sometimes (often) an update will fail to install and reboot, and then the tablet will claim you're up to date when you check for updates. So you'll have to manually update yourself, and often, if only works if you start from .182, and flash each file in order. So here's how.
Thanks to @slayeralive for these instructions.
First things first, install your drivers if you haven't, and set up ADB. Use the files below if you have trouble.
Universal Naked Driver 0.73
Minimal ADB & Fastboot 1.1.3
Now make sure USB debugging is enabled on your tablet. Go to Settings > About tablet, and tap on Build Number about 8 times, I think, and you'll see a toast, "You are now a developer!" Back out once and you'll see Developer Options. Enter, and near the top you'll see an option for USB debugging, so check that box. Plug in your tablet to the PC, then open a command line interface (Hit Windows Key + R, then type in "cmd" and press enter). Type in "adb devices" and look at your tablet's screen for a prompt. Check the box and tap OK. Now press up and enter, and you'll see your tablet's serial number and the word "device" if you did it correctly. Now you're ready for the next part.
1. Root with ROOT ZenFone.
2. Turn on USB debugging if you haven't already (see above).
3. Download the ROM or update(s) and rename it update.zip and transfer it to your tablet. Or copy all files to the tablet and rename them as you go.
4. Download a file manager that has root access (such as ES File Explorer or Root Browser Lite).
5. Go to / (root) and manually copy your update.zip to the /data folder.
6. Download this command file and copy it to the /cache/recovery folder. This must be done every time, so leave a copy in your SD card.
7. Open ADB and type line by line (or copy and right-click/paste into the command line window):
NOTE: When you type in the "su" command for the first time, it will prompt for SuperSU access on your tablet. You must allow it or the following won't work!
adb shell su echo 'boot-recovery ' > /cache/recovery/command echo '--update_package=/data/update.zip' >> /cache/recovery/command echo '--wipe_cache' >> /cache/recovery/command echo 'reboot' >> /cache/recovery/command reboot recovery
If you are getting an error on update, then you will likely have to flash .182 first and go from there, flashing each OTA in order using the coded commands above every time.
