  • Click on "Download" : SPFT is now waiting for a device a COM port to Flash
  • Remove your battery from your device, or unplug it, or make sure your device if off
  • Plug your device to your PC with USB cable (a good cable, on a direct back USB port, avoid front USB ports)

Flash CWM Recovery & Root your device
Flash CWM Recovery & Root your device

Scatters


Generic Guide
  • Make sure to have the MTK driver properly installed (look at POST #2)
  • Download the compatible SP Flash Tool for your device from POST #1
  • Download the compatible Custom Recovery for your device from POST #1
  • Download the SuperSU ZIP available at http://download.chainfire.eu/supersu and put this zip on your Internal Memory (or External SDCard)
  • Get the appropriate Scatter for your device (also available in the Firmware directory)
  • Run Flash_Tool.exe has an administrator
  • Click on "Scatter Loading" and choose the scatter MTxxx_Android_scatter_emmc.txt file
  • Unckeck all the partition except the recovery one in order to flash only the recovery
  • Click on the recovery path, and choose the CWM Recovery file to flash
  • You should have something like :
    SPFT v3 :
    SPFT S510

    SPFT v5 :
  • Click on "Download" : SPFT is now waiting for a device a COM port to Flash
  • Remove your battery from your device, or unplug it, or make sure your device if off
  • Plug your device to your PC with USB cable (a good cable, on a direct back USB port, avoid front USB ports)
  • The flashing process will start automatically : do not unplug your USB cable !
  • A red bar for COM loading, a purple bar for Preloader Flashing, a yellow bar for Firmware flashing
  • Wait for a Green Circle saying the flash process is finished
    SPFT v3 :


  • Unplug the USB cable, close SPFT, but don't power on your device
  • Boot your device directly into Recovery with the key combination (it's Vol- + Power on many MTK devices, but could be different depending the device)

    Recovery key combination for Jade (S55), Jade S (S56), Jade Z (S57) :
    1. When the device is totally off, press Volume-UP button and HOLD it
    2. Press Power button (keep holding Volume-UP), and HOLD both of Power & Volume-UP
    3. When the device vibrates for the first time, release Power, but keep holding Volume-UP
    4. As soon as it vibrates a second time, move from Volume-UP button (release it) to Volume-DOWN button (hold it)
    5. It vibrates again, you can release all buttons and recovery is loaded

  • You can now Flash SuperSU zip in order to gain Root
  • Reboot your device :
    - You should answer Yes when asking "Disable Flash Recovery"
    - You should answer No when asking to "Push root with /system/xbin/su"
    This happens because CWM don't regconize very well the su binary installed by SuperSU (it's looking for the superuser one)
  • Enjoy Root & CWM !

NB : If you power on your device after the CWM flash, there is many chance that the system will erase the recovery by the stock one.
In this case, CWM is lost, and you should make the Guide again and make sure to Reboot into CWM right after the flashing process.

Very useful post!

I've been waiting for rooting my E700 for a while. One thing I'm not sure is that if this method only works with an older firmware. I upgraded my phone and now it has Acer_AV0K0_E39_1.020.00_AAP_GEN1. I was wondering if it is necessary to downgrade (flash the stock rom provided in this post) first, or I can simply flash CWM and then flash SuperSU.

Another question is that if I do downgrade first and then root, would the root be removed once upgraded via OTA?

I think you can directly flash CWM and flash SuperSU, it should work fine
The only thing is with CWM and Root, OTA may not work anymore, so you will have to unroot and maybe flash back the original Recovery to upgrade via OTA.

For E700 (E39) - I somehow get only partial root.

I use a utility called RASHR which backs up recovery but it failed with an error about busybox.

I have installed busybox as well, but still had the same error.

In anycase I found that the Root for Unite 2 works properly - http://forum.xda-developers.com/show...8&postcount=65

I'd rather use SuperSU if someone can find a solution.

I'm not sure I understand what you do
Did you follow my Guide ? Are you using CWM ?
