Thanks a lot. Successfully rooted my tablet.

One question. After rooting I rebooted into recovery. The stock recovery booted up. Is there a way to keep the CWM recovery flashed during the rooting process?

We can't flash it for now
This exploit only can boot it
We need to unlock the tab to be able to flash something

Great Guide!

Unfortunately it doesn't work with the very similar A1-840HD:

Hi there,
How did you guys manage to install the MTP device drivers (the one that pops up in Device Manager when you enable the USB debbugging)? I´m on a Windows 7 (32 bits) and the folder we are instructed to download and unzip apparently does not contain the required files/driver.
Any help is appreciated as I can´t manage to pass that initial point.

Thanks in advance,
Mix

EDIT: I eventually got it to install correctly by using the USB Driver package from Acer:

I used the option in the toolkit which installs the drivers. If I remember correctly once you run the .bat file and ACCEPT you are given this option. I used 32 bit version of Win 7 as well.

I just got the Acer Iconia A1-840FHD from a BestBuy and I want root access.
PLEASE somebody find out how!

I am hoping to get Linux up and running to run WINE on it since it is x86 architecture from being Intel.

Edit:Why did they make the name so similar?
I have the "rootable" FHD and yet there is an HD as well.
I hope rooting still works.
Then again,according to the manufacturing date,they have barely been out.

Did you try this guide?
I'm not sure I understand your post and what you want to do.

My product and safety information booklet says FHD on it despite mine only having 1GB of RAM.
Is there a root method working on the A1-840HD?

I may try Kingo since they still get updates and just added an exploit for Nexus Android 4.4.4 as well.
I hope it has support for this device.

Is there any way to step back and put everything as it was without root?

For any reason if we need to send the device to the warranty, this should be like original system state.
