I have Asus Fonepad 7 dual sim (Build ver. 5.5.1).

I want to root my device.

adb devices recognizes my device properly.

Debugging mode is on.

Even device enters in fastboot mode by executing adb reboot-bootloader in terminal (I am using Ubuntu 14.04).

I have set up android rules in /etc/udev/rules.d/99-android.rules .

I've found out my vendor id and product id using lsusb (when the device is in fastboot mode). I've made corresponding entry in android rules file. But even that didn't help.

I've tried sudo fastboot devices also. Every time I get nothing but a blank line.

Somebody please help!!

  • Could you provide the lsusb line for the device and what you've added to the udev rules? – Matthew Read Mar 18 '15 at 16:58
  • And please also check lsusb when booted into fastboot mode. I've seen several devices presenting different IDs depending whether they'd been booted to fastboot, recovery, or normal. Check you've got them all covered in your UDEV file. – Izzy Mar 18 '15 at 17:01
  • When I am in fastboot mode lsusb gives me Bus 002 Device 008: ID 8087:09ef Intel Corp. for my device. Corresponding udev entry is SUBSYSTEM=="usb", ATTRS{idVendor}=="8087", ATTRS{idProduct}=="09ef", MODE="0666",OWNER="aniket",GROUP="plugdev" @Matthew Read @Izzy – 2ndGenCore_i5 Mar 18 '15 at 17:41
  • Glad you got it rooted! I've moved my comment to an answer and reorganized. (Rather than editing the title, you can Accept an answer with the checkmark near the up and down arrows.) – Matthew Read Mar 20 '15 at 14:12

A bit of googling indicates that several people have had to build fastboot specifically to work with this device. I found this one for Linux (last post) and have verified that it runs and isn't malicious: https://software.intel.com/en-us/forums/topic/494961

  • That actually worked just fine! This link provided me "working version" of fastboot for my device. Now fastboot devices returns my device name correctly and all other fastboot commands work just fine. – 2ndGenCore_i5 Mar 20 '15 at 11:27
