[Windows 8 Development and Hacking] Thatgrass:
I am not responsible for any damage happening to your device by doing this!

I believe Windows 8 is great for productivity, but that's not Always what we are looking for. We want to experiment with our devices and get as much out of them as possible. Android gives us the freedom to do with this tablet what we never thought possible, the overall performance is incredible and graphics are buttery smooth. However, I couldn't find a suitable guide, so I created one myself. So let's get started!

Bug list:

Everything should be working fine, contact me if not

Requirements:

USB Stick with at least 512 MB storage

USB Keyboard

USB-hub, because the tablet only has 1 USB port

Latest image available for Generic UEFI Installer from here

Image Writer Tool from here

Setting up a bootable USB

1. Download Image Writer Tool, unpack it and run the ''Win32DiskImager.exe" file

2. Once opened, navigate to your *.img file you downloaded earlier in the requirements and hit "Write" (This will format the USB drive)

3. Let it run and once it's done your USB is good to go.
​

Setting up tablet to boot from USB

1. Enter BIOS settings by pressing the power (and hold it) and the Windows button

2. Once there, make sure UEFI boot modus is set​

Booting from USB

1. Make sure your tablet is turned off

2. Plugin your USB-hub with USB Stick and Keyboard insered

3. Power on your devices while pressing the ''F12'' button

4. Now choose your USB device from the boot options

5. You'll get a few options, choose the option that fits your expectations

Note: I'd dualboot and install gummibootloader

6. Choose your prefered option and wait, the installation will run automatically

7. Once done, unplug everything and power off the device

8. When you turn your tablet back on, you'll see (if you've chosen option a. or b.) a menu with the option to boot Windows or Android

9. Navigate with volume DOWN key and select with volume UP key
​

This Method could also be used for the Samsung XE700T

Q:

What other devices will also be combatible with this method?

A:

Q:

How to get bluetooth mouse and keyboard working on Android and Windows at the same time?

A:

1. Pair your bluetooth devices first with android and the with Windows

2. On Windows download PsExec

3.Then from downloaded file copy PsExec.exe in Windows to directory C:\Windows\System32 or to directory where your System32 folder is.

4. Write in the search cmd and run it as administrator

5. Then use command: psexec -s -i regedit.exe

6. Now go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Keys

7. From \Keys you can find your paired bluetooth devices. First there is the devices bluetooh mac address and 32 numbers long linkkey. Now write those linkeys and mac addresses up or copy them.

8. Now everything is set on Windows side. Next boot to android.

9. On android you need again for example ES file Explorer and R/W rights

10. With file Explorer fro root go to /data/misc/bluedroid/

11. Open file called BT_config.xml

12. From text find your devices using mac address

13. When you find you devices mac addres scroll down and you should see line with linkkey and 32 number code.

14. Now take that 32 number code you got from Windows

15 You have to change it little so the linkey works and here how it's done:

for example your Windows linkkey is "12345678qwertyuiasdfghjkpoiuytre" now set it as 8 number clusters like this

"12345678 qwertyui asdfghjk poiuytre"

Now you have to reverse those 8 number clusters

Take the set on far right "poiuytre" and mark it like this "po iu yt re"

Now reverse those pairs like this "re yt iu po"

Now "reytiupo" this is the first line in the new linkkey

Do the same for other three cluster. After it's done this example linkkey looks like this "reytiupojkghdfasuityerqw78563412"

16. When you have your modified Windows linkkey ready you can just replace the old one from the file BT_config.xml

17. Now just reboot android and your keyboard and mouse should work.

Q: How to change DPI from 213 to 160 (or something else)

A:

1. Get file manager on android like ES file Explorer

2. R/W rights to whole system on android

3. From root go to /system/etc/machine-props/

4. Open acer-w700.prop with ES Explorer and edit line "ro.sf.lcd_density = 213" and change 213 to 160

5. Reboot android and system should now be 160 DPI
