    Good Afternoon,

    When I put the line mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system i am receiving a permission denied message. Operation not permitted. Can you please help.

  2. Chelsea says:

    i keep getting the message “mount-o: permission denied” and when I try to enable super user it asks for a password… help?

  3. Stephanie says:

    I get to the su password and I don’t know what to enter as well. HELP!

    Otherwise if I do mount-o I get the permission denied as well.

    What about getting rid of all the other files that installed as a result of running the ‘runme.bat’ script? The script appears to install BusyBox, recovery.apk, zergRush in addition to Superuser.apk and su.
    I would like to un-root the Kindle and completely restore back to factory settings before sending it in for warranty work if needed. So how would I go about doing that?
    After following your un-root steps, would a simple ‘Reset to Factory Defaults’ under Settings >Device, then choosing to ‘Erase Everything’ do the trick?
    Thanks

    I am using Ubuntu 11.10. I got the Kindle fire rooted, but now I want the prime video streaming working again so I want to unroot. When I use the ./adb-linux shell script I get the following error:

    error: insufficient permissions for device

    Any help would be great.
    Thx.

    HELP!! I rooted my kindle fire and ran into issues running twrp. I decided to retry but now I am having bigger problems. When I try to root is says that adbd can not run as root in production builds. After research I found that this was probably because I am already running in root. So when I try unrooting no operation works. I have tried the unroot utility as well as your method however in your method it says su permission denied. Please help me!!

  11. S. P. Burnside says:

    Or better yet, just download and install user 6.2.2 back in the Fire. Worked like a charm for me. And easier than all that other BS.

  12. Parthasarathy Chandran says:

    I installed jelly bean and I didn’t take a back up of my previous kindle software. Now I want to get back to the original software and I tried following this instruction. But, it says device not found. I am using a Mac. This is not the machine in which I rooted my computer with. Can someone help me?

    address and thought I might as well check things out.

    finding out about your web page yet again.
