[Android Q&A, Help & Troubleshooting] Kinslayer81:
English instructions :)

Well, with some help from Google Translate and some creative interpretations, I managed to do this and thought I'd provide some English instructions for others (with some added comments) :)

DISCLAIMER: AS USUAL, YOU SHOULD KNOW THAT FOLLOWING THESE ACTIONS (AND ESPECIALLY FOLLOWING THEM INCORRECTLY) CAN BRICK YOUR DEVICE (I.E. YOUR DEVICE WILL STOP WORKING, POSSIBLY PERMANENTLY). I AM NOT RESPONSIBLE FOR ANY DAMAGES THAT MAY ARISE FROM YOU FOLLOWING THESE INSTRUCTIONS, YOU DO SO AT YOUR OWN RISK.

Downloads

1. Windows -- the Arrows TAB USB driver Download.

2. Easy rooting toolkit (ERT) for Arrows Tab F-01D (ver 1.0) Download

3. goroh_kun's lsm_disabler.ko Download

Info

4. A su binary, such as the one found in DooMLoRD_v3_ROOT-zergRush-busybox-su.zip

5. Android SDK platform tools. adb(.exe) (and in Windows, specifically: AdbWinApi.dll, AdbWinUsbApi.dll)

Preparation

1. Unzip ert4F01D.zip, and in the subdirectory 'files' place:

* adb.exe (Windows only, from step 4 above)

* AdbWinApi.dll (Windows only, from step 4 above)

* AdbWinUsbApi.dll (Windows only, from step 4 above)

* lsm_disabler.ko (from step 3 above)

* su (from step 5 above)

2. Before connecting the USB, in Settings -> Applications -> Development:

* Check (tick) USB debugging ("Debug mode when USB is connected")

* Check (tick) Stay awake ("Screen will never sleep while charging")

3. Set up the USB drivers and Android Development stuff if you haven't already. I don't use Windows so can't help with this.

The Dirty Work

At this stage, you can run the batch file. Since I don't use Windows, I did the steps by hand, so you'll have to correlate your actions appropriately (I can't read Japanese either, so your guess is as good as mine :)).

1. On your PC:

adb shell "mv /data/local/calib.dat /data/local/calib.dat_"

adb shell "ln -s /data/local.prop /data/local/calib.dat"

2. On the tablet, go into Google Maps, touch the GPS icon ("locate me" icon) on the top right hand corner, and then touch the BACK key to exit.

3. On your PC:

adb shell "echo ro.kernel.qemu=1 > /data/local.prop"

adb shell "rm /data/local/calib.dat"

adb shell "mv /data/local/calib.dat_ /data/local/calib.dat"

adb reboot

5. Once the device has fully rebooted, on your PC:

adb shell "mkdir /data/local/lib"

adb push files\lsm_disabler.ko /data/local/lib/

adb shell "insmod /data/local/lib/lsm_disabler.ko"

adb shell "mkdir /data/local/bin"

adb shell "echo '#!/system/bin/sh' > /data/local/bin/autoexec.sh"

adb shell "echo '/system/xbin/soff' >> /data/local/bin/autoexec.sh"

adb shell "chmod 755 /data/local/bin/autoexec.sh"

adb shell "mount -o rw,remount /system /system"

adb shell "ln -s /data/local/bin/autoexec.sh /system/etc/install-recovery.sh"

adb push files\su /system/xbin/

adb shell "chown root.root /system/xbin/su"

adb shell "chmod 06755 /system/xbin/su"

adb shell "echo insmod /data/local/lib/lsm_disabler.ko > /system/xbin/soff"

adb shell "chmod 755 /system/xbin/soff"

adb shell "mount -o ro,remount /system /system"

adb shell "echo > /data/local.prop"

6. I think at this point I was just meant to exit the lock screen.

7. adb reboot

8. Congratulations. You're now rooted. Go to the Play Store and download "Superuser" (by ChainsDD) and "BusyBox" (by Stericson). If you decide to buy BusyBox Pro, do not check the "symlinks" option in version 8.0, otherwise it's game over (no wifi, no adb shell, no root, no remount). It's a pain, but not impossible to repair this situation, see http://xdaforums.com/showthread.php?p=26964465. I've emailed the author and I hope future versions won't trash the system so easily.

After all this, I'd suggest download Titanium Backup for Root users, backing everything up, and uninstall the all the bloatware that came with the device. Read up elsewhere about Titanium Backup.

Let me know if this helped you! Not sure how many other English speakers are using this device :)
