ATTENTION / WARNING / ACHTUNG!!!!!!!

Efun (distributor of what we know as the "Nextbook Premium 8SE") in fact sells two different tablets marketed under the same name. This rooting method will ONLY work with a Nextbook Premium 8SE running a Rockchip processor.

**Am very sorry if this has already been posted, searched and did not find anything.**

Soon after purchasing my Nextbook Premium 8 se I learned that many Roms, apks, etc. that I couldn't find via Google (in English, anyhow) are easily found in Italian.

Which brings me to what I found today

androidworldDOTit/forum/mediacom-smartpad-810c-381/%5Brom%5D%5Bics-4-1-1%5D%5Bxteam-4-0-jellybean%5D%5Bmediacom-810c%5D-67171/

Run that through Google Translate if like me you don't speak a word of Italian.



All right, time to sit down and write a guide to doing this. First things first: I didn't do any of this work! People like Devmonkey, Sunnyboy167, deeno33, and FinlessBob, (over at Freaktab) and Xteam at Android World Italy are the ones who've put in the legwork and hours to make this stuff possible. I'm just gathering their work in to one place.

Before you begin: Back up all your things if you want to keep them!

Also, remove your micro sd card from the Nextbook. I darn near fried mine because I didn't.

Next: You know the drill. You're a big boy, (or girl, or whatever. I'm not here to judge) I, nor anyone else is responsible if anything bad happens to your device, to you, your happiness, or your hard earned money or your time. YOU are choosing to root your device and install Jellybean on to it and YOU assume all responsibility. Cool? Also, this will probably void your warranty. But let's face it, if you're here, you probably don't care too much about your warranty anyway. Let's get rocking.

STEP 1: Make sure you have the device drivers installed for your Nextbook on your computer.
I'm using a Windows 7 64 bit desktop. I imagine that other Windows desktops pre Win 8 will be similar. If you're using Linux, I believe that drivers aren't necessary. But hey, if you've installed Ubuntu, Arch Bang, Puppy, etc, you've probably got this figured out anyway.

Turn off your Nextbook Tablet Connect the micro usb cord to it, then hold in the volume up and down keys while plugging it in to your computer.

"NOTE: On your screen you should see a bubble pop up in the lower-right corner saying "Installing drivers". Most likely it will say it can't find the drivers. This is normal. Continue following the steps to install the missing drivers.


Step 2: Open the Device manager by typing mmc devmgmt.msc into your "Run" box on XP or search box in start menu on Windows 7 and hitting enter (you can also find Device Manager in your Control Panel options in Windows 7).

Step 3: With your N8 still in an off state and plugged in via USB you should see a yellow exclamation symbol somewhere next to "Unknown Device" in the list of devices in the Device Manager. Right click on it and select "Update driver software".

Step 4: Now it will prompt you to choose how you want to search for it. Select "Browse my computer for driver software" and it will bring up a window for you to navigate manually to the driver location which is in the "drivers" sub-folder in the NEXTBOOK8ROOT folder. Select which ever system you have (32bit or 64bit) and then hit "OK". You might go thru one or two prompts before it actually installs. Just "OK" everything and you should be fine." ~Sunnyboy167

Ok, now that the device drivers are installed you'll want to download the file linked from here: zippyshareDOTcom/v/60864398/fileDOThtml

Sorry, I have less than 10 posts, so you'll need to convert the dots to, you know, dots. I get why the site does that.

Scan that thing for any nasties, and then unzip it wherever you'd like. (I used my desktop) Open it and click on the folder "Mediacom 810c" Inside you'll find a file named "Rk29update.exe." Open it. You'll see a box like this:


See attached picture

That is what it will look like if your tablet is not hooked up to your computer. So if it isn't (which it should be, since I never told you to disconnect it) reconnect it now.

Click the box that says "loader," then click "Formatta!!" Which, as you might have guessed is Italian for "Format." No going back now, kid.

Let the thing run its course, it'll take a couple of minutes. Once it's done, click the box that says "Aggiorna!!" This will install Jellybean on to your Nextbook. Be patient, as this will take a few minutes. You'll hear your computer make the "device disconnected" sound, and you'll be all set. You can unplug your Nextbook from your computer now.

First boot up of the device on Jellybean was a touch slow for me, but don't panic. Once you've gotten through set up the Rom runs incredibly smooth and fast. The first screen you'll see will be the welcome (benvenuto) screen. You can select English (or your preferred language) from the drop down menu. From this point on it should be smooth sailing. Google Now works like a charm, Project Butter seems to really make a difference on this tablet, camera works, notifications work, everything seems good. There are minor bugs here and there, but nothing Earth shattering.

One last thing: for a $99 budget "craplet" from Big Lots, you could do a lot worse than this tablet. I've found it pretty sturdy, highly customizable, and generally responsive and fun to use. I also own a Nexus 7, and while this clearly can't touch it spec wise, it's definitely a fun second device to keep around.

ok, so far so good. The Rom is very responsive, Google Now is working well. Only thing to note, which I should have known: Take out your micro sd card first! I ended up corrupting mine when I flashed the Rom. (And guess where I had everything backed up too? = fail)

But again, other than that, this Rom is awesome

Request for Bug List
Thanks for posting about this Italian Rom for the Nextbook 8. I am thinking about installing it. Can you provide a list of bugs that you've noticed?

Thanks again!

of course!

As mentioned in the install guide, take out any MicroSD card, as you might damage it. That said, however, upon another reading of the original Italian install guide, apparently the "data system corrupted" bug that I took for being my MSD card being screwed up is in fact a known bug that is actually affecting internal memory, but only temporarily. The solution is to simply format it on device, and everything will work fine. The option to format is given as a push notification immediately upon getting through the sign in process, and nothing in actuality appears to be damaged, but until I did the format I could not access anything on my MSD card.

The big recurring one I've noticed may or may not be unique to this Rom, as my device had it before on a gingerbread Rom; namely, the battery charge level never seems to change. It always seems to be at 100% right up until it drops dead, no warning. Actually, that's not entirely accurate, because if it runs out, and I charge it and unplug while the charge shows a number less than 100% the battery icon will continue to show "charging" until 100% (even though unplugged) and then stay there.

When waking the tablet up it takes a couple of seconds to reconnect to wifi. Any notifications coming in will slow it down for up to a couple of minutes. I've noticed that if I try and use it during this time I occasionally "overload" the device, and end up with it rebooting. My best advice: wake it, give it a second to go from "no internet connection" to having found wifi, unlock the screen, and then wait about 1 minute before doing any heavy use until any notifications pop up; once you do that you're good to go.

If I think of or notice anything else hopefully I'll remember to edit this post.

After I leave it charging, it goes into the sleep of death I guess? I don't know if this is because I had some apps downloading in the background. Also, my auto rotate doesn't work. I don't know if there's a fix for it, but so far, I havent found any

but besides those 2 things, the rom works great!

I'm having a hell of a time getting drivers for Windows 7 installed. Can someone point me in the direction to the drivers and possibly driver install instructions? .
I have tried with and without USB debugging turned on. In device manager I see M3-chip with USB debugging on. The only thing I can figure is I have the wrong drivers.
I have a Nextbook Premium 8 SE.
TIA

Good job gettin stuff together...i been trying to make it easier for folks to understand all this in the official nextbook 8se root thread. Info is so jumbled and most people dont read through the thread far enough to make sense of what they've just downloaded...lolz. anyways good work and heres a link to another great JB rom for this tab....big props to OMA for his work on this. I been runnin it for a 2 months now and i love it!! http://forum.xda-developers.com/show....php?t=1903745 This one can be tricky with the kernel and the system image so please follow directions carefully if you decide to try this rom...i had issues with bricks (my fault of course) but nothing the rk flasher tool cant fix. And of course backup, backup, backup, nuff said[COLOR="Silver"]
