Sounds like your environment is not set up right. Here is a video that shows how to set the path for the SDK platform tools http://m.youtube.com/watch?v=oaNM-lt_aHw

If you want to copy/paste the path in your environment on here I can see if it looks right.

Edit: Until fastboot is recognised nothing will move forward custom ROM wise.

Hi I'm just wanting to double check as I had a couple of issues rooting yesterday the KF First Aide method didn't work for me on my version 8.4.8 and I ended up stuck with an unusable KF for half an hour as it was so sluggish and nothing would load. Good news was I took a deep breath and tried option two on the easy root method which worked perfectly. To be honest I may have made an error when trying the KF First Aide method so I'm not sure it doesn't work on all 8.4.8 KF 8.9.

So I now have root and sdk works great I just want to know if this will work on my KF 8.4.8 8.9". Just a little worried about bricking after my challenges yesterday.

Also what is the benefit of rooting over sideloading googleplay and my launcher/apps of choice?

I also had no success with KF First Aide with 8.4.8 and ended up using a different method for root. I used seokhun's instructions earlier this evening for installing the 2nd bootloader + TWRP and it worked fine and I've since booted into TWRP, performed a backup from within TWRP, rebooted, etc without issue.

Awesome thanks for letting me know. I'll give it a go. Tentatively but I'll do it. :laugh:
My wife asked why I do this every time I get a new device. For me it's about freedom and accomplishment. Haven't rooted the nexus 5 yet though.

Hello iyousif, forget KFfirstaid stuff.. Many problems.. Take this answer from KFHD8.9 Q&A. http://xdaforums.com/showthread.php?t=2672696 (Page 3, #21, links included there) In the dev area are grate how to tutorials, specially from hashcode. Its bullet prove but take care. Make the right downloads with md5 check for your specific device and take care of the sw versions on your current device. Flashing files for other devices or corrupted downloads or using wrong procedures kills the cat.

Thanks a lot for giving feedback!

I can't get to [Restore] screen with this script at all!

Right now my Kindle act so slow, and the installed Root verfication apps keep saying I am not having Root.\

The problem is that the script doesn't seem to see the device, it doesn't reboot. I tried almost all options (0-4) Which one is the correct one?

I am using the latest version (33) , but also tried 29, 30

I'm not with stupid, I am stupid

Anyone have any ideas on my issue ( http://xdaforums.com/showthread.php?p=53049089#post53049089 ) ? I'm trying to avoid reposting it in detail, especially as I decided to be lazy and not do it manually as shown in this thread and royally F***ed myself.

I read your post on the other thread. First of all fastboot cables don't work with the 8.9 so that is a dead end. You should be able to get into fastboot with a little troubleshooting. Most likely the issue is that the driver on your pc got messed up. Go to one of the adb troubleshooting threads to get that sorted.

Did you happen to back up a good system image? If you did then you can flash your backup using adb commands in fastboot once you get it fixed and start over with getting twrp installed.

Thanks for the reply. Yeah I realized I made good backups of it before the flash, so just reflashed those and things worked out the second time around. Just a blonde moment for me. Thanks for the help though!

I've just run into a strange problem. Been using TWRP without issue for many months, but today I tried to reboot to recovery to do a nandroid and just got a black screen. I get the orange and then blue logos, and I got the graphics glitch on the right-hand side as usual, but then the screen goes black and there's nothing. If I plug it in to my PC I can reboot to recovery through adb and TWRP works as normal, but I can't get to it by pressing the power and vol buttons. If I press the power button again the device reboots as normal and everything works fine (running Hashcode's CM11).

I tried reflashing TWRP 2.7 from fastboot (just the recovery, didn't want to touch the bootloader), the flash went fine, but I still have the same problem. The tablet's working fine in normal mode, but it would be useful to be able to get to recovery without having to adb. Before today I never had any problems with recovery. I did a nandroid restore a couple of days ago (had been playing with themes and managed to load one that FCd settings, so I restored a backup), and that seemed to go without a hitch.

Any ideas? Should I reflash the bootloader?

problem installing stack os 8.4.9

Hi, My Kindle Fire HD 8.9 is rooted with superuser installed. The device is running 8.4.9 OS. I was able to successfully install the first line of the shell using adb. However, the second line of the shell command will not install, with the response from the device being: cannot execute permission denied. I have not powered down or rebooted the device and am still in adb mode. I did save the stock partitions to my computer HD. Am I in big trouble? Any suggestions? Thanks for your response...I will keep everything "as-is" until I hear advice from you. Thanks!

Can you confirm what lines you mean? The ones from the backup section or which exactly?

The line was the second line in the stack install section. However, I got lucky! Rather than do anything else or unplug the usb cable I took a gamble by going to settings and restoring the device to factory settings. The device now boots up as new, without root, and works well.

My basic question is now: can my Kindle Fire HD 8.9 4g with the 8.4.9 OS be rooted and fastboot installed to run pure android? Any suggestions as to how and/or links? Any help would be very much appreciated!

You should be able to downgrade the firmware, then root and flash without any problems. However as far as I know, the 4G isn't working on any of the current ROMs (I could be out of date on this, I have the WiFi only one)
