[MeMO Pad 7 General] RootTheMachine:
This guide will help you unbrick your hardbricked MeMo pad or possibly other device. For the purpose of this guide, hardbricked will refer to a device's software being damaged to the point where standard procedures and utilities (adb, fastboot, recovery, etc.) will not be able to make the device functional again. In order to be hardbricked, you essentially need to erase or damage the bootloader. Without the bootloader, you can't use fastboot or recovery since all of those things require the bootloader. This guide addresses that situation (your device should be displaying nothing but the USB logo, as seen in the attachment). If you have a working bootloader and can run fastboot commands, THIS GUIDE IS NOT FOR YOU and will only possibly make things worse.

This guide is directed towards the ME170CX, which is also apparently called the ME70C or KO1A; however, the same process should work for other MeMo Pad devices and even other Intel devices. I cannot provide much help for other devices, so try at your own risk.

Do not follow this guide unless it is your last hope or you know what you are doing. I am not responsible for any damage you cause to your device in any way.

We will use the Intel Phone Flash tool, which can be used with a variety of Intel devices to flash firmware. You can use the Manufacturing Flash Tool instead if you'd like.

Here are the steps:

Obtain and install all drivers and software from the bottom of this post.

Download the factory image zip from the manufacturer's website; make sure it matches your device before flashing!. Extract the contents of the zip. Extract the contents of ifwi.zip into the same folder.

Plug in the device and open the Phone Flash tool. In the Phone Flash Tool window, click on "Custom Flash" on the left and pick "system (blankphone)" from the Type dropdown.

For each of the first four files, pick the one that matches:

CLVp_CSAX_FWR_DnX_20.3E.bin for FW DnX

IFWI_v64.25_CSAX_PROD.bin for IFWI

CLVp_CSAX_OS_DnX_20.3E.bin for OS DnX

fastboot.img for OS Image (this doesn't seem right, but it worked for me)

Once the four images are in place, click "Register flash file". At this point, your device should be displayed in the white rectangle on the page and the start flash button should now be clickable. Press the button, and flashing will commence. If you see "Windriver Error: 0x20000015, Timeout expired" in the console, try rebooting the device and flashing before the USB logo comes up (the device will appear in the Flash Tool before the logo comes up).

After a few seconds, you should see the Intel splash screen and you will be taken to droidboot. From there, it should be fairly easy to recover the device.

If you encounter any issues or corrections, please respond to this thread and let me know. Also, I was getting tons of driver errors (Windriver Error: 0x20000015, Timeout expired) the second time I tried to do this. The trick seems to be pressing the flash button before the USB logo appears.

I discovered most of this information from these two resources:
