[MeMO Pad 7 General] GuyInDogSuit:
[me176c/x] [K013] How to Root and update from .182 to Lollipop release

Stock ROMs up to v.182, all languages

ASUS' Download Center for the MeMo Pad 7 Link is now inaccessible as ASUS has redesigned their site. Even the support page for this tablet no longer has any links to download ROMs/updates. Sad panda. However, the ones below (ASUS' direct links included) still work! I am also in the process of reuploading/rehosting all of these as well, so stay tuned! So far everything is rehosted on Google Drive, and I plan to add more mirrors in the next couple of days. Pleasse bear with my snarkiness, I have been up late and it's now 4am. I must crash now.

Anyway........ Enjoy!!

(Manually) Flashing Updates

Sometimes (read: 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 (and we know it's full of crap). So you'll have to manually update yourself, and often, if only works if you start from .182 (or above), and flash each file in consecutive order. So here's how it works. Be sure to read over this before starting, to get an idea of what's in store for you. And to be safe, read it again. And to be doubly-sure, read it AGAIN (I cannot stress this enough).

Obligatory warnings:

Your warranty (expired by now, for sure) is now null and void. Regardless of whether you do this, it's no longer valid either way! :laugh:

I am not liable for any damages to your device (or your brain) that this process may cause. What you do to your device is on you, but if you play it safe and read this all carefully (and read it again! And AGAIN!), you shouldn't have any trouble.

Instructions:

First things first, install your drivers if you haven't already, and set up the Android Platform Tools (adb and fastboot exes and such, also attached to this OP). I highly suggest trying the Latest ADB Fastboot and USB Driver installer tool for Windows by @fawazahmed0 (or the various attached drivers below, if you still somehow have trouble with getting your PC to recognize this dinosaur of a device).

Next, before we continue, make sure USB debugging is enabled on your tablet. Go to Settings > About tablet, and tap on Build Number 7 times, and you'll see a toast, "You are now a developer!" Back out once and scroll down a bit, you'll now 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" (without quotes) and look at your tablet's screen for a prompt. Check the box and tap OK. Now. back in the command prompt, press up and enter on your keyboard (which will repeat that last command), and you'll see your tablet's serial number (a string of letters/numbers) and the word "device" if you did it correctly. Now you're ready for the next part.

1. Install the "RootZenFone-1.4.6.8r.apk" (attached to this OP, below) and run it. Beware, it may have some Chinese text/Engrish. It's fairly simple to figure out though, thankfully.

2. Turn on USB debugging if you haven't already (didn't you read this first? You're already slacking!).

3. Download the zip file(s) you need and rename it update.zip and transfer it to your tablet. Or copy all files to the tablet and rename them (with a file manager of your choice, see next step) as you go.

4. Download a file manager that has root access (such as MiXplorer or Root Browser).

5. Go to / (root) and manually copy your update.zip to the /data folder.

6. Download this command file (also attached below, in a zip) and copy it to the /cache/recovery folder. This must be present each time you install an update via this method, so leave a copy on your device.

7. Back to Windows Command Prompt, run the command, "adb shell" (without quotes, as before), wait a moment for it to reload the server, then type, "su" (again, without quotes). When you type in the "su" command for the first time, it will prompt for SuperSU access on your tablet, similar to how it requested the RSA perms with adb debugging. You must allow this root permission, or the following won't work!Now, type line by line (or better yet, copy and paste into the command prompt (a right click automatically pastes copied text into it, btw):

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

In brief, what this means is that you just ordered the "command" file to boot as a "recovery" in order to flash the update package you copied and renamed previously. Thus, the tablet will reboot and commence flashing. At least, I think that's what's happening here. Sorry, I'm no rocket surgeon. All I know, is that it works. However, if you are getting an error during the update process, as mentioned above, you will likely have to flash the next incremental update (the one just above your current version) instead and go from there, flashing each OTA in order using the coded commands above every time. Be sure to rename EACH ZIP to "update.zip" as you do this or the command cannot find the file! Yes, this sounds like a pain, and it is! But this has worked when the direct approach had failed.
