[Asus Fonepad 7] G.Ashwinkumar:
Thanks op for the guide finally recovered my Asus Fe170CG. I did face a few issues while following the above steps and i'll say how i solved them so that it is useful for someone else.

1) Driver Installation:

Follow this youtube video (www.youtube.com/watch?v=71YAIw7_-kg ) to disable signature verification. Now all the following steps (the entire process) needs to be done in this mode (do not reboot the system).

->First you have to install the iSocUSB driver. Right click the file and run as administrator. Follow the onscreen installation process. While doing so you'll get two Windows Security prompts with a red font click on "Install this driver software anyway" both the times. The iSocUSB driver will successfully get installed.

->Next install the Intel USB driver by running it as administrator and following on screen prompts.

->Next install the Asus Usb Driver as shown in this video (www.youtube.com/watch?v=0XpQ1DS63UM). At the end of Asus driver installation you'll get and "error code 10" message ignore it and proceed to the next step. You have to follow the same procedure as in the previous video but instead of selecting Asus Android ADB Interface in Model you now select the second option i.e Asus Android Bootloader Interface and keep proceeding till you have installed for all the five Models as shown in www.imgur.com/a/P4X0ewk Now you have successfully installed all necessary drivers and are good to go. Do not reboot the system.

2) Next install the Xftsk downloader and if the drivers have been installed properly it will launch successfully in Windows 10. If it doesn't then its a driver issue so uninstall all drivers and repeat step 1 properly.

3-8) Follow steps 3 to 8 as stated in OP. If "fastboot exit" shows error simple press volume down button till you see the shutdown option and press power menu to select it. And disconnect phone from pc.

9) The download link shows Asus Flashtool version 1.0.0.45 but for me this version doesn't have our model listed (Asus Fe170cg not in list). So i used Version 1.0.0.14 (www.asusflashtool.com) as shown in Ops picture. www.ibb.co/kaSiOb

Follow the steps as shown in the above picture and click on Start. Now enter droidboot mode in phone( Now press together Vol + and Power button at the same time , it will vibrate but don't release keys , once ASUS logo appear release both keys and fast press just Vol - button several times until you see USB logo and Droid Boot screen a) and plug back usb cable. Asus flash tools will detect your device with the fastboot Serial Number. Click on this and start the process. After it has done its job it will show Flash Image successfully.

If Asus Flash tool doesn't recognize the device you can try the following fastboot commands (not tested by me) to flash the raw firmware.

1. fastboot devices ( see if it is recognized: else plug out usb and plugin again)

2. fastboot oem erase_osip_header

3. fastboot oem start_partitioning

4. fastboot flash /tmp/partition.tbl partition.tbl

5. fastboot oem partition /tmp/partition.tbl

6. fastboot erase system

7. fastboot erase cache

8. fastboot erase data

9. fastboot erase APD

10. fastboot erase ADF

11. fastboot oem wipe splashscreen

12. fastboot oem stop_partitioning

13. fastboot flash splashscreen splash_sign.bin

14. fastboot flash token MFG_BOM_Full.bin

15. fastboot flash ifwi ifwi-prod.bin

16. fastboot flash boot boot_sign.bin

17. fastboot flash recovery recovery_sign.bin

18. fastboot flash fastboot droidboot_sign.bin

19. fastboot flash APD APD.img

20. fastboot flash system system.img

21. fastboot reboot

Note: None of this is my work just put it together for others to follow easily

Yes as Teddy Lo suggested your drivers aren't installed properly. Check my post for a detailed explanation on how to install them properly.
