[GUIDE][MAC] How to Unlock and Root the Xoom with a Mac

This is a super simple method taken from Arcadia 310 on another thread.
This is assuming you have The Android SDK already installed and updated.
Download these files XoomRoot.zip HERE
and FASTBOOT for MAC - HERE
Unzip both archives into your ~/sdk/platform-tools folder.
I AM NOT RESPONSIBLE FOR YOU SCREWING UP YOUR DEVICE, THIS IS VOIDING YOUR WARRANTY ANYWAYS. HIT ME UP ON TWITTER OR HERE IF YOU NEED HELP OR HAVE QUESTION. ON TO DIRECTIONS.
Follow these steps: (After you have unzipped into your folder)
1. Follow the pre requisites above.
2. Open a terminal (located in the utilities folder)
3. Navigate to your sdk/platform-tools folder
Example: "cd /home/b16/Desktop/sdk/platform-tools" (no quotes)
4. Type "./adb devices" and make sure your Xoom shows up on the list.
This command will show you if your device is connected to the Android Debug Bridge.
5. Now type in "./adb reboot bootloader" (You can skip the next 3 steps if you’ve unlocked with fastboot previously)
This will reboot your device into bootloader mode accepting fastboot commands.
6. I had to type "chmod 755 fastboot" first to get it to execute.
This will change the permissions of the FASTBOOT BINARY so it can execute.
7. Now type in "./fastboot oem unlock" and choose to unlock it. (wait for reboot)
This will make your device "Hackable" and will VOID your warranty, you can re-lock it later if you like using another guide on this forum. Located HERE.
8. Once it has rebooted type "adb reboot bootloader" and hit enter.
Now you are going back into bootloader mode to finish the job.
9. Once in bootloader mode type "./fastboot flash boot rootboot.img"
This is going to flash the boot image needed to have root working properly within the system.
10. Type "./fastboot reboot" (wait for reboot)
command wil now boot you back into Android.
11. Type "./adb remount"
We are now mounting the system partition in order to push the Super User binary.
12. Type "./adb push su /system/bin"
Does what it says. Pushes binary to system folder.
13. Type "./adb shell" You should now see a "#" sign.
This will put you into a root shell to change the permissions of files in the next step.
14. Type "chmod 4755 /system/bin/su"
You just changed the permissions of the super user binary to run properly.
15. Type "exit".
You will now be back in your home terminal ready to push the Super User Apk.
16. Type "./adb push Superuser.apk /system/app"
You should now have root acces! Enjoy!

Thanks for posting this. Another thing I did, because I use ADB quite frequently, was add the SDK tools to my path. For those that need help, it looks something like this:
Open Terminal and type echo 'export PATH=~/Downloads/android-sdk-mac_x86/tools:$PATH' >> ~/.profile
This only works if your SDK folder is in your Downloads folder inside your Home folder.
The next time you open a Terminal window, you can simply type adb remount or whatever you need without having to add the ./
Another bonus is this makes it much easier to keep kernels, ROMs, and modules out of your SDK tools folder, where they do not belong.

First off thanks for doing this... I figured out my n1 and I can do this too... I'm stuck at the chmod 775 line... I enter that command and its like I didn't enter it... after I proceed to fast boot OEM unlock it tells me that it can't be executed .. what am I doing wrong... God I hate being noobed out... I'm so close!!!

EDIT: got past that with the help of using fastboot-mac from htc's website... but now I'm stuck on getting the rootboot.img over
Morgan-Brants-Mac-minilatform-tools Chongo$ ./fastboot-mac flash boot rootboot.img
sending 'boot' (2902 KB)... OKAY
writing 'boot'... FAILED (remote: (0000000f))

EDIT2: Well it was due to my xoom being almost dead (not enough juice to flash)
on the other hand this was a refresher course and I now understand ADB a whole lot more... thank you for this educational piece I am now a tiger blood enfused SUPER USER

I am glad I could help, I have this tutorial on my website along with many other devices, http://rootzwiki.com if there is any other devices you would like to see

Well the default shell in a mac is bash so wouldn't be:
Code:
echo "export PATH=$HOME/bin/android-sdk-mac_x86/tools:$HOME/bin/android-sdk-mac_x86/platform-tools:$PATH" > .bash_profile
This is a video walkthru of rooting that happens to be on a Mac but the process is the same for Windows:
http://www.youtube.com/watch?v=4YkIw0y_Os4

im not sure if it is just me or not, but i get stuck at step 5 for some reason?
i type ./adb reboot bootloader it shuts down then turns on and i get stuck at "starting fastboot protocal support" it sits forever then i have to hold volume up and power to reboot and its fine, but cant ever get past that.
it no longer shows as attached device at that point either

Magenta you say.

OK, thanks for the initial post and outstanding directions. I've updated what you listed based on what I have seen on my mac. I've just been through this process now and everything is working great. I hope this helps.
1. Follow the pre requisites above.
* I also had to download the fastboot-mac file from the HTC site- http://developer.htc.com/adp.html​
2. Open a terminal (located in the utilities folder)
3. Navigate to your sdk/platform-tools folder
Example: "cd /home/b16/Desktop/sdk/platform-tools" (no quotes)
4. Type "./adb devices" and make sure your Xoom shows up on the list.
This command will show you if your device is connected to the Android Debug Bridge.
goonmac-2: platform-tools goon$ ./adb devices
List of devices attached
028040c743e111d7 device​
5. Now type in "./adb reboot bootloader" (You can skip the next 3 steps if you’ve unlocked with fastboot previously)
This will reboot your device into bootloader mode accepting fastboot commands.
FYI - your xoom will just say "Starting..." but it is ready to accept the next step.​
6. I had to type "chmod 755 fastboot" first to get it to execute.
This will change the permissions of the FASTBOOT BINARY so it can execute.
7. Now type in "./fastboot oem unlock" and choose to unlock it. (wait for reboot)
This will make your device "Hackable" and will VOID your warranty, you can re-lock it later if you like using another guide on this forum. Located HERE.
goonmac-2: platform-tools goon$ ./fastboot-mac oem unlock
... INFO To continue, follow instructions on the device's display...
OKAY​
8. Once it has rebooted type "adb reboot bootloader" and hit enter.
Now you are going back into bootloader mode to finish the job.
*after the reboot, initially, I got this error:
goonmac-2: platform-tools goon$ ./adb reboot bootloader
error: device not found
when the reboot completes, you will come to the original setup screen. it is worth noting that you need to select the language and follow the on screen directions. Re-enter your account information etc. When you get to the desktop, your device will then be re-seen by your mac.​
9. Once in bootloader mode type "./fastboot flash boot rootboot.img"
This is going to flash the boot image needed to have root working properly within the system.
* Again, need to use the fastboot-mac:
goonmac-2: platform-tools goon$ ./fastboot-mac flash boot rootboot.img
sending 'boot' (2902 KB)... OKAY
writing 'boot'... OKAY​
10. Type "./fastboot reboot" (wait for reboot)
command wil now boot you back into Android.
* Again, need to use the fastboot-mac:
goonmac-2: platform-tools goon$ ./fastboot-mac reboot
rebooting... ​
11. Type "./adb remount"
We are now mounting the system partition in order to push the Super User binary.
no issues
goonmac-2: platform-tools goon$ ./adb remount
remount succeeded​
12. Type "./adb push su /system/bin"
Does what it says. Pushes binary to system folder.
no issue
goonmac-2: platform-tools goon$ ./adb push su /system/bin
701 KB/s (26336 bytes in 0.036s)​
13. Type "./adb shell" You should now see a "#" sign.
This will put you into a root shell to change the permissions of files in the next step.
no issue
goonmac-2: platform-tools goon$ ./adb shell​
14. Type "chmod 4755 /system/bin/su"
You just changed the permissions of the super user binary to run properly.
no issue
# chmod 4755 /system/bin/su​
15. Type "exit".
You will now be back in your home terminal ready to push the Super User Apk.
16. Type "./adb push Superuser.apk /system/app"
no issue
goonmac-2: platform-tools goon$ ./adb push Superuser.apk /system/app
1137 KB/s (196521 bytes in 0.168s)​

still stuck at same step, after ./adb reboot fastboot i cant go any farther, the xoom just isnt connected to recieve and additional commands, heres a copy n paste from my terminal...

any help/suggestions?

Are you using the Mac fastboot binary? I'm not by my computer right now, but I believe the Mac version is called fastboot-mac by default. Download it, make sure it's executable (chmod 755 fastboot-mac), then try fastboot-mac oem unlock. After you run adb reboot bootloader, you will lose your ADB connection, and your Xoom won't display anything but the boot logo and something about starting fastboot. This is your cue to unlock. Hope this helps.

For some respason I didnt realize the difference between the two fastboots until he mentioned that and thankfully your ad was right above with the link to htc thanks to you guys im now have rooted and unlocked and overclocked my xoom and its incredible now! Thanks for the patience with me

I did a video that was done on my MAC in the MAC OS. If anyone wants a more visual way to see how this is performed. I follow all these steps exactly. I show how I set my environment PATH, and this actually is what tripped me up, because my user profile wasn't looking at the PATHs I originally setup, but all that is required is entering
echo 'export PATH=xyz:$PATH' >> ~/.bash_profile (this whole line )
Where 'xyz' is your path to the android-sdk/platform-tools/ from the root of your Hard Drive, for most Macs it should be ' /Users/[Ur User Name]/android-sdk/platform-tools '

Hope this helps

I also have a WiFi Xoom Video Tutorial available available as well. Check it out.
http://www.youtube.com/watch?v=zC6J-hV6SM4
I try to go over common hiccups that I have seen some users have come across as well in the video.

I'm getting the following error:
./fastboot-mac flash boot rootboot.img
sending 'boot' (2902 KB)... ERROR: usb_write failed with status e00002ed
FAILED (data transfer failure (No such file or directory))
fastboot-mac is chmod 755, rootboot.img is there, alongside it, I'm in as root and it's still failing for me.
Edit: Nevermind. Right after pulling the reboot before the rootboot.img - or boot.img for wifi users - immediately go into the aforesaid command and it should work just fine.
Took me a couple of times.

Can you unroot on mac?

Help with How to Install CM7 to Kindle Fire on WINDOWS 7

Here is the process
adb shell
cd cache
mkdir recovery
cd /
cp /sdcard/log /cache/recovery/
cp /sdcard/last_log /cache/recovery/
dd if=/sdcard/updaterecovery.img of=/dev/block/platform/mmci-omap-hs.1/by-name/recovery
idme bootmode 0x5001
reboot
The cp command doesn't work on windows, IDK why but thats how it is, i figured I substitute cat /mnt/sdcard instead of cp/sdcard, but again dd command doesn't work even with /mnt/sdcard. Can someone please help me through the rest of the process? And no i don't have linux/mac computers.
Here are the rest of the steps
Now in recovery, you will see that the first option highlighted, is Install update.zip from sdcard. Press the Power button (ok).
When prompted to install, press the Power button again. The recovery is modded because it can’t be navigated through right now. No here is actually Yes so just select that.
Once the ROM is flashed, without rebooting your phone, open up command prompt or terminal and navigate to the location where the stock recovery is.
Now enter the following commands:
adb shell
mount sdcard
exit
adb push/sbin/
dd if=/sbin/stockrecovery.img of=/dev/block/platform/mmci-omap-hs.1/by-name/recovery
adb reboot
The device will reboot twice now, and once it’s done, the CM7 logo will appear. For updates and queries,

It's simple install Ubuntu in windows using wubi .... It installs like a program and then u boot into it ... Don't be afraid of a penguin ....
You may just fall in love with a real operating system and check out mint ... Too

i believe you are missing a "su" command after adb shell

Yeah....you need adb shell, then SU to make the prompt go from $ to #. Try the commands then. They all work in win7, as I did it last night....three or four times.

Wrong forum!!!

I am stuck on:
Now enter the following commands:
adb shell
mount sdcard
exit
adb push/sbin/
dd if=/sbin/stockrecovery.img of=/dev/block/platform/mmci-omap-hs.1/by-name/recovery
adb reboot
it just wont mount the sdcard says its busy, nevermind i rebooted and it worked.
But now i am stuck on the sbin part, i must be missing something
Ok, once again nevermind, i just modified the first recovery command to:
dd if=/sdcard/stockrecovery.img of=/dev/block/platform/mmci-omap-hs.1/by-name/recovery
and it worked out at cm7 boot anim right now.

Try "ADB shell" then "Su" then "Mount /sdcard"
Minus the " "

Can't seem to catch a break - adb and fastboot issues

Hey y'all,
I am rooting / rom-ing my third KF.
I could not get TWRP to install so I installed CWM that comes with the KFU
I installed Jandycane and the most current gapps
From then on, the Kindle gets stuck at the boot animation
I have tried other options in KFU, but everything involving fastboot does not work. The kindle shows up as a composite device in the device manager, and is able to be adb-ed into.
In KFU, I see the bootmode being 4000. When I tried the idme command to change it to recovery, it told me that it could not accept the idme command.
I've tried going using the adb shell to push fiels and create directories, but have failed. Su does not work, mkdir does not work, and chmod does not work.
Additionally I have tried the KF Unbrick 1.1 and none of the options seem to do anything.
I am running out of options here. I have tried these procedures on two PCs without avail.
Before I installed the current rom, I have made a backup of the stock rom. Is there any way I could adb into the device and restore it? Would this be a valid way to fix this up?
Can anyone suggest anything else that I have not tried?

Anyone?

So much for adb ... how about that fastboot
Every time I do anything with fastboot it says waiting for device:
Code:
C:\Users\xxx\Desktop\Kindle Fire Utility\tools>fastboot -i 0x1949 flash recovery twrp.img
< waiting for device >
Are there any devices showing?

fastboot does not see any devices whereas adb does...
I have tried sending the fastboot command while the device is off and then turning it on. The kindle just hangs at the kindle fire screen.
EDIT: I switched computers, and it got back into previous state at being stuck at the animation screen
This is what happens when I try to install TWRP in KFU:
Code:
Installing TWRP...
If we get stuck here for awhile, power the kindle on and off a few times.
You should also check device manager for "kindle" If so, rerun the driver
installer that came packaged with KFU.

Can you actually put your device into fastboot mode? You can only use fastboot commands when the bootloader has put the device into fastboot mode. If you can get output from any adb commands, you are not in fastboot mode. Look at this guide and see if you can put the KF into fastboot mode...
http://forum.xda-developers.com/showthread.php?t=1668159
What bootloader do you have installed on the device? (Describe the first bootlogo you see. Refer to the above guide.)
What error do you get when you attempt to set the bootmode with idme?
Where are you running your adb commands? When you are stuck on the boot animation or in recovery?
Can you even get to your recovery?
My guess is you've somehow corrupted the system software on your ROM installation. If you can get to recovery, you'll probably need to reflash your ROM. If you can get the device into fastboot mode, you can get to recovery. If can't do either of those, you'll need a factory cable or be willing to open up the case.

That would make sense. I cannot change the bootmode from 4000, so that's why fastboot does not work. I feel dumb for not thinking this through.
It has CWM installed as I could not load TWRP initially due to a poor connection.
This is what I get when I try to change the bootmode:
Code:
C:\Users\xxx\Desktop\Kindle Fire Utility\tools>adb shell su -c 'idme bootmode 4002'
Segmentation fault
<idme> write 4002 to offset 0x1000
C:\Users\xxx\Desktop\Kindle Fire Utility\tools>adb shell idme bootmode 4002
<idme> Invalid permission
I cannot get into recovery as I cannot get the tablet to boot into anything but the ROM istelf (or try to, as it never boots into anything but just loops the boot animation)
Tell me about this factory cable. I'm sure I have it somewhere among all of my micro USB cables...
The boot pattern is as follows: kindle fire (white orange/stock) -> jandycane boot animation that runs forever
There is no triangle or any press the power button to boot into recovery.

I cannot get the kindle to boot into a ROM, so I cannot use the terminal app.
Can I get an adb shell and push these files?
Also, per my post above, it seems that something sketch is going on with my superuser settings...

Yes, if you have a working adb, you can absolutely push those files. The path will be slightly different though. Instead of ~/local/tmp, you will push the files to /data/local/tmp then execute:
Code:
adb shell chmod 755 /data/local/tmp/rcmode
adb shell /data/local/tmp/rcmode
Looking through your other posts I see you are trying to invoke the shell and enter the commands seperately. Try again, but only this time add "adb shell" to the command itself, as above, and see if that makes a difference.
Also, I've seen both /data/local and /data/local/tmp used but I've always used /data/local/tmp
[Edit:] if you still get a "No such file or directory" error, see if you can create it:
Code:
adb shell mkdir /data/local/tmp

KFU's included version of CWM recovery does not flash ICS (and very likely JB) ROMS correctly. This is a bug known to corrupt the flash.
It not likely you'll be able to do anything meaningful with the system currently installed on your Kindle Fire. Unfortunately for you, that probably includes using idme or pushing anything that might help you change bootmodes. Of course, I may be wrong and you might find another way out of the mess, but the easiest way for you to fix this is to use a factory cable, put the KF into fastboot mode, flash TWRP, boot into recovery so you can flash a new bootloader and ROM.

I hadn't really thought about mounting the data partition...it's worth a shot either way.

Well my adventure just keeps getting worse and worse. I charged the kindle last night to ensure enough battery life for today. It is suck at the kindle fire logo now. I have the drivers loaded correctly and my computer sees the kindle. However I cannot adb or fastboot the device. It also went from composite device to adb device in the device manager.
EDIT:
Was able to install FFF and got to boot into recovery. CWM 5.2.0.7.
In adb I tried to get super user permissions
C:\android-sdk-windows\platform-tools>adb shell

What are my options at this point. KFU cannot download and install TWRP. I cannot manually push it since I dont have su. KFU's install super user function does not work as it tries to install TWRP.

Ok, so while I was in CWM, I mounted the SD card, downloaded and transfered a flashable TWRP found here http://forum.xda-developers.com/showpost.php?p=28664718&postcount=127
I flashed the zip and now I have TWRP working.

Click to expand...
Click to collapse
With the Kindle powered down, type the following command into a cmd/terminal window on your PC (should return with: < waiting for device> ):
fastboot -i 0x1949 getvar product
Then connect USB to the Kindle and it will boot. It *SHOULD* show a Fastboot screen and your terminal window should show something like:
product: Jem-PVT-Prod-04 this has to be done in a command window opened where fastboot is located. Shift + right click in the folder where fastboot is located select open command window here, then run the command and follow above instructions to get it into fastboot.
Edit also to let you know if you are running system version 8.4.1 other thing will need to be done to install freedom boot and recovery just to send an air of caution if you use the present instructions for this you will become stuck at the blue kindle fire logo so I would wait till methods have been updated.

yes I did that, unplugged my kindle and powered down -> type the command in cmd < waiting for device> -> Plug my kindle in and automatically turn on
The cmd still show < waiting for device> even after it's fully boot, it doesn't show fastboot screen
I managed to go to Fastboot mode by using KF First Aide, but my computer couldn't recognize kindle while it's in fastboot mode. So I couldn't do anything
Edit 1st post: I'm using 8.3.1 rooted

Thepooch helped me through teamviewer on how to install Android and here I share my experience on how to do it.
Your kindle need to be rooted. I suggest to use KF First Aide and root. It's easier
You will need ADB enable by go to settings in Kindle.
Download this file (Amazon 8.4.1 OS): http://d-h.st/VnR and put it in sdcard for backup purpose.
You don't extract ZIP files.
1. Download and extract #1 on below link
http://forum.xda-developers.com/showthread.php?t=2191010
2. Go to Root_with_Restore_by_Bin4ry_v21\stuff -> Shift + Right Click on folder -> Open command window here
*Steps 3,4,5,6,7 are from http://forum.xda-developers.com/showthread.php?t=2128201
3. Use these command to backup your stock partitions, these *.img will be in the Root_with_Restore_by_Bin4ry_v21\stuff folder.
Take 4 of those *.img to somewhere else safe
Code:
adb shell su -c "dd if=/dev/block/mmcblk0boot0 of=/sdcard/boot0block.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/boot of=/sdcard/stock-boot.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/recovery of=/sdcard/stock-recovery.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/system of=/sdcard/stock-system.img"
adb pull /sdcard/boot0block.img
adb pull /sdcard/stock-boot.img
adb pull /sdcard/stock-recovery.img
adb pull /sdcard/stock-system.img
4. Download these files (go to different topic above for latest version)
http://goo.im/devs/Hashcode/jem/stack
http://goo.im/devs/Hashcode/jem/kfhd8-freedom-boot-8.3.0.img
http://goo.im/devs/Hashcode/jem/kfhd8-twrp-2.4.4.0-recovery.img
5. Install stack:
Code:
adb push stack* /data/local/tmp/
adb shell su -c "dd if=/data/local/tmp/stack of=/dev/block/platform/omap/omap_hsmmc.1/by-name/system bs=6519488 seek=1"
*Replace stack with location to your stack file
Example: adb push C:\Users\Admin\Desktop\stack /data/local/tmp/
6. Stop the auto recovery update script (this file may or may not be present): Mine was not present, it will show file not sound after enter 2nd command
Code:
adb shell su -c "mount -o remount,rw ext4 /system"
adb shell su -c "mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak"
adb shell su -c "mount -o remount,ro ext4 /system"
6.5: APPLIES IF YOU ARE ON SOFTWARE VERSION 8.3.0 OR GREATER
Download this: http://goo.im/devs/Hashcode/jem/kfhd8-u-boot-prod-8.1.4.bin
Enter fastboot mode and flash:
Code:
fastboot -i 0x1949 getvar product
fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin
*You will need a file called fastboot.exe, open command from there, KF First Aide have it
or you can download from here: http://d-h.st/ttL <- Do not use anything from this, just go to tools and open command from there
7. Continue with these command in fastboot mode:
Code:
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.3.0.img
fastboot -i 0x1949 flash recovery kfhd8-twrp-2.4.4.0-recovery.img
fastboot -i 0x1949 reboot
***If everything is done correctly, when you booting up, the word Kindle Fire should switch from orange -> blue -> orange, then fully boot
***If you get orange screen, then you didn't do step 6.5
8. Download these and put them in sdcard:
http://goo.im/devs/Hashcode/jem/cm10.1/cm-10.1-20130604-UNOFFICIAL-jem.zip
http://goo.im/gapps/gapps-jb-20130301-signed.zip
To enter recovery mode, unplug, shut the kindle down. Plug in (it should power on), when the word Kindle Fire is orange, hold the volume up button, it should switch to blue and then twrp recovery mode. If you failed, hold the power button until it shut down and try again.
8.5. Drivers problem: Kindle not recognized
When I get into recovery mode, my computer couldn't recognize Kindle. So this is what you have to do.
Download this and extract: http://d-h.st/9We
Open android_winusb.inf
Go to/Search for
Code:
;Kindle Fire HD
Now go to Device Manager -> Right Click on "couldn't recognize driver kindle" -> Details -> you will see there are two codes.
Edit android_winusb.inf (below your device, mine is Kindle Fire HD) to match with the two codes.
Then just right click, update driver
9. Now back to Kindle, you should be in TWRP Recovery Mode.
You should backup first: Go to backup -> backup everything and check compression
Next go to Wipe -> Wipe 4 of the thing on the first line (Caches, Dalvik Caches, Factory Reset, System)
Next go to Install, choose 2 of the files at step 8.
Code:
cm-10.1-20130604-UNOFFICIAL-jem.zip
gapps-jb-20130301-signed.zip
Then reboot system
10. Now you should see CyanogenMod (Android) loading
After you are in, don't let Google backup your things. It will somehow messed up your system and will crash when you try to run apps.
Next, go to settings, go to about, and tap the last line 8 times to enable developer mode
Next, check advanced boot and ADB
After that, when hold your power button for a little bit, you will see a boot button, tap it and there should be 3 options to boot in case something happens.

Nice job you make a helper proud.

[Q] Need help to go back to stock OS

Hello friends,
I have Kindle Fire HD 8.9. I installed CM 11 on it six months ago using this method http://forum.xda-developers.com/showthread.php?t=2128175 and have been using it without any major problem since then. But I feel sluggishness in its performance so I want to switch back to stock Amazon OS. I had made a backup of stock OS using the method described in above mention thread, i.e.
adb shell su -c "dd if=/dev/block/mmcblk0boot0 of=/sdcard/boot0block.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/boot of=/sdcard/stock-boot.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/recovery of=/sdcard/stock-recovery.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/system of=/sdcard/stock-system.img" # This will take a few minutes
adb pull /sdcard/boot0block.img
adb pull /sdcard/stock-boot.img
adb pull /sdcard/stock-recovery.img
Now I have those four files (bootblock.img, stock-boot.img, stock-recovery.img and stock-system.img) on my HDD.
If I want to go back to stock OS, I would do following steps, and I want to know if that is the proper way to proceed. and is there something I must do during the whole process in order to succeed or must be mindful of?
Plug in your fastboot cable and reboot so that you see the fastboot screen and enter the following commands:
Code:
fastboot -i 0x1949 flash boot boot.img
fastboot -i 0x1949 flash recovery recovery.img
fastboot -i 0x1949 flash system system.img # This one will take a few minutes
fastboot -i 0x1949 reboot
or should I follow instructions given here http://forum.xda-developers.com/showthread.php?t=2011126
some suggestions or instructions would be of great help. Thank you.

Both serve.
If you use your files you will return to the version that originally had in the tablet. If you use the link, you will return to the above versions (8.1.4, 8.1.3 or 8.1.2).
I do not recommend re-stock. CM11 is faster than any stock.

Yes, I did find CM11 much productive than stock Amazon OS but over time I witnessed deterioration in performance. I am in no way trying to say that it is because of CM,it could have been low hardware of Kindle.
Anyway, I used the backup made by TWRP and restored Kindle to its initial state(i.e. rooted and Google Play installed). At this moment I am on version 8.4.9. I have two questions, what if I install latest OTA? Would I loose TWRP and Root? and eventually ability to install a new ROM again? Or TWRP would be still there after OTA?

After latest OTA 8.5.1, TWRP and root permission is gone and Kindle is back to its original condition.
