How to verify your phone is "rooted"

Hi all,
I've recently flashed to MoDaCo 2.2 however I'm just assuming my device got rooted at the same time - but I don't know for sure.
What's the easiest way to verify it has been rooted?
Thanks!

1. use search forum or google..
2. adb shell su
thats it

It keeps saying device not found, but works for my mytouch and G1. Any ideas?

Have you enabled USB debugging? Settings-Applications-Development

Yup did that too...my other phones pick it up no issues.

I also get the exact same problem (i.e. Device not found) - I guess it is a hint that it isn't rooted maybe (although I assumed it was automatic with flashing MoDaCo 2.2)?

Sound like a problem with your driver. But you should have been able to connect before to install the custom rom?
Download astro file manager and you should be able to see files that you couldn't see before

OK I got a work around. You need to restore your PC to a point BEFORE you plug in your hero. I did this and now works great.

How I might undo root process?
I think that replace chmod 4755 permision to default in the "su" file, but I don't know how to
No need to do, but I'm intererested in the concept

There is a thread on how to unroot:
Open Windows Console and connect Hero with PC
write this:
fastboot boot cm-hero-recovery.img
adb shell mount /system
adb shell rm /system/app/Superuser.apk
adb shell rm /system/bin/su
adb shell reboot

How to Unroot Kindle Fire! [Win/Mac/Linux][Video]

Here's how to unroot Kindle fire using adb, works on Windows, Mac, and Linux:
Step 1. Download adb.zip and unzip, you should get a folder called adb.
Download adb.zip
Step 2. Open up a command prompt or terminal and type:
For Windows:
cd \adb
For Mac or Linux:
cd /adb
Step 3. Type the following to get into ADB shell:
For Windows:
adb shell
For Mac:
./adb-mac shell
For Linux:
./adb-linux shell
Step 4. Copy and paste the following to enable read/write on filesystem:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Step 5. Type the following to remove rooting files:
rm /system/app/Superuser.apk
rm /system/bin/su
rm /system/xbin/su
Step 6. Type the following to reboot and your Kindle Fire should be fully unrooted!
reboot

Excellent instructions for both root and unroot, thank you. I wasn't aware of typing "su" though before step 4. Thankfully you covered that in the video.

Yes, should edit to mention su

Awesome!

Yep, nice concise post, but need to add a couple of things:
1. su before the mount command.
2. /system/bin/su doesn't always exist as it depends on what root method you used.
For me, only the xbin version existed, so people shouldn't freak out if they get a "No such file or directory" message!

Ota rootkeeper
Once the Kindle Fire is rooted, OTA ROOTKEEPER app allows you to easily root/unroot (i.e. you want to see Amazon Premium videos. Only allowed if unrooted.)
Once you unroot/root with OTA Rootkeeper, you will need to restart for new settings to take.
To see youtube video, search OTA Rootkeeper Kindle.
Download via Google Android Market.
Works great

Just stop the Amazon video app. There is no need to reboot. I use Advance Task Manager Pro personally because I purchased it for use with my Archos tablets but it isn't necessary you can do it through Settings-> Applications also.

Thanks SO MUCH! Definitely add this to your Kindle if you're trying to keep hacking it but can't stand to be without all six seasons of LOST.

Mount Issue
When I run the command to mount i get the following error:
mount: Operation not permitted
I'm using Mac OS 10.7.2
Nevermind!! Just had to see the "su" command in the tutorial. Sorry.

I have to unroot so I can send my KF back to Amazon.
If I user the OTA RootKeepr, is their anyway for them to figure out it was rooted? Once I use that app, I just wipe my KF? Thats it?

Just update to 6.2.1 and it should wipe it.

Hi... I have a kindle fire ver 6.3 I am trying to unroot it but when i get to adb shell, it said device not found... i have installed android sdk, and kindle driver but no help... please advise!

Thanks for the nice contribution! Covered both! No need to worry how to root or unroot.
Would like to read more tips on using the Kindle Fire as the tablet column I came across in aneesoft.

I followed the method and unrooted my kindle. I found one issue after rebooting , it gave error " android.process.acore" has stopped working. As per Zedomax suggestion, I did Factory reset and problem was solved
Thanks for helping!!

[Q] Kindle Fire with 6.3 Help with Rooting Please

Hi,
I am a total noob. I don't even know the proper expressions for this whole thing.
So this is my case:
I am outside the US and bought the Kindle Fire with a 6.3 firmware, couple of days ago.
Being curious about what it all can do, created a fake account with a test credit card as I read somewhere in the net.
Then downloaded the KFU 0.9.5 and rooted the device, everything went according to the plan, so I thought.
Then I discovered I had to use something called Market Opener to install other apps. But this Market Opener never worked.
So I found out that I had to change permissions. But this cannot happen as I get that message that adb services can not run in production builds etc. whatever that may mean.
So I downloaded Android SDK, followed the instructions installed it but I still cannot get into the root and change folder permissions. Sometimes it recognizes the device, sometimes not and when it does it tells me the same thing as above.
Then I would need some .apk to do the thing on the device but I cannot install those as I don't have the Market Opener or the Google Play and I cannot get those if I don't have superuser permissions to change things in Folders.
Basically I have been spending the last 3 days in searching the net for answers but to no avail.
So, can someone help me please? What I need to do is being able to install some apps including Market Opener / Google Play and being able to watch Amazon VOD. Is this possible?
Please bear in mind that I have no clue of the specific language, i.e. I don't know what flash is and how to do it nor I know how to do a backup and restore or how to reset everything in the original state.
SO if some of you have the patience to help, please advice me with some noob language so that I can understand.
Thanks in advance for the help that will come

Are you looking to put a custom rom on it or just root? If you're looking to keep Amazon services, you can put MoDaCo's rom on it, which is just like your kindle out of the box with a few extra bells and whistles. There are alot of guides floating around on how to get ADB working. There's an excellent beginners guide in the General section that I highly advise checking out.
Noob terms: if you want to keep the Amazon experience, I reccomend MoDaCo. Look for it in the development fourms.

Thanks for ur answer.
I have read a lot of guides out there but I seem not to be able to get the ADB working as I always get the message I gave in the original post plus the fact that sometimes it recognizes the device and sometimes not.
I have read the beginners guide which was excellent but without the ADB working there is little I can do I suppose.
As I wrote, I want to play with the device to see what it is able to do and want to use the Amazon VOD if possible. I.e. I would like to be able to use Google Play to get apps on will and still keep the Amazon services. Would that be possible with the MoDaCo staff?
Ok. I downloaded the MoDaCo staff.
Must I reset the kindle to the factory settings before I install that? If yes, how?
And how do I flash it?

Make sure you are in fact rooted.
You seem like you know enough about adb to try the following commands.
adb shell
ls /system/xbin
Look for a file called "su" in the list
Then...
ls /system/app
Look for a file called "Superuser.apk"
A lack of either of these means you're not rooted and may be the source of your problems
If you are trying to change system file permissions through adb...
adb root
adb remount
adb shell chmod blah /blah/blah/yadayada
Just don't literally type "blah /blah/blah/yadayada"
Sent from my Amazon Kindle Fire using xda premium

a factory reset won't really help you because you're basically replacing the operating system. pretty sure all amazon services are working with modaco. to install it, look around for a guide on how to install something called firefirefire (FFF) and TWRP. pretty sure that can all be done with kfu in a couple clicks. then copy the modaco zip onto your kindle, go into the wipe menu and clear out system, cache, dalvik cache, and data (factory reset), then go into install and choose the modaco zip. reboot and you should be set.

Thank you for your answer.
I would gladly follow your advice but the adb does not find my device. I don't know whether this is normal and if I must reboot my PC.
The kfu also gives me an offline status...

Thanks again for the fast answer. I am impressed!
Doesn't the FFF and the TWRP get installed automatically with the kfu?

its most likely your computer. a reboot might help. if not, how did you install the drivers? are you using a mac or pc? try installing the drivers that came bundled with KFU.
if you're using a PC, go into device manager and see if something about android ADB pops up. if not, it's your drivers.

haha, no problem .
if FFF was installed, you should see a picture of fire in a caution sign or an android logo over the kindle fire logo when you boot it up. if all you see is kindle fire, then you don't have fff. im pretty sure you need fff to get into twrp. if fff is installed, you should be able to hop into fastboot and install twrp if it's not installed yet.

I am using a PC ( a netbook, don't laugh, I'm on vacation!!)
I installed the drivers using the install_bat from the kfu.
In device manager I see Android Phone and underneath Android Composite ADB Interface...

interesting. check my previous post and see if you have FFF installed. adb should be working fine if device manager can find it. if you can, run adb devices into cmd and see if it picks up your kindle. not sure if the stock rom has a development switch in the settings.. if there's an option to enable usb debugging, make sure that is on. if not, just try moving usb ports and running adb devices.

If adb has trouble recognizing your device, it means it's a driver issue. Either Windows, KFU or a combination of the two causes the drivers to fail for some reason.
Uninstall/delete your current drivers in device manager (may require reboot)
Turn your Kindle off
Reinstall drivers
Turn your Kindle on
Retry adb commands

that's fantastic... if you have FFF, try pressing the power button a couple times as it turns on and see if you can get into recovery. you shouldn't need adb now. if you can get into recovery, just wipe and flash the new rom. if you don't, you can use fastboot to install it.

[Q] Kindle Fire 8.4.9 Root?

Just got a "factory refurbished" Kindle Fire 8.9 HD for a STEAL (Amazon gave $50 back on the refurb).
Anyway, now that I have it and have been playing with it for a few weeks, I've realized that the current root methods (including Root Many Android) say they have rooted it, but I don't quite have all the SU access. Digging deeper, I've found that I have System Version 8.4.9.
I can get a partial root, but cannot mount the system to RW
Anyone out there working on the Root of Kindle Fire 8.4.9?

I would just downgrade it and flash a custom rom.

Stunts,
I'd love to do that, but one of the issues with the current root is I can't use KFFirstAide to do much of anything. I would like to keep the KF as close to stock as I can, as I have kids and the FreeTime app is nice. I'm mostly looking to get the Google Play store up and working.
I've done a search but don't see anything on how to downgrade the KF from 8.4.9 without having root.
What am I missing?

You don't need root. When you initially power the device on it should briefly be detected as a jem device. Download then drivers in my signature and extract them somewhere. Now open the device manager and plug the kindle in while off, when you see the jem device, right click it and hit update drivers, and tell it to look where you extracted mine. If this is windows 8 you will have to disable driver signature enforcement first. If you can manage to get this step completed the rest is simple, it basically involves this: grab a utility like kindle fire first aid and shift + right click it and hit new command window here. With the kindle off and unplugged type
Code:
fastboot -I 0x1949 getvar product
once it says waiting for device plug the kindle in while it is off, it should enter fastboot, from there you can use kffa to downgrade it.

Would You Like To Wipe Data And Cache (y/n) ?
After this, I wipe data and cache and then didn't finish the registration (so I didn't get "pushed" an update, just in case)
Come back up and I'm still in 8.4.9
I've gone in to dropbox and pulled all the images to my computer. Is there a way to move these and get them properly mounted in adb? I'm a relative n00b but getting a bit more comfy in the adb environment and may be able to do it from there, with a bit of help?

Do not actually use KFFA use this method --> http://forum.xda-developers.com/showthread.php?t=2468988
You only need kffa for adb.exe and fastboot.exe ect.
PS. Be sure NOT to to connect to the Internet after until you have OTA blocked, and if you Like you can manually upgrade to what ever firmware you would like, I went back to v848

Now I'm stuck in the Kindle Fire boot screen - orange. I got through all the flashes without an issue and unplugged on the final reboot per your instructions. I try to adb to it and there are no devices found.
Edit: Whoops. Was using my old shortcut command keys (arrows) and just changed what flashed to system - forgot to flash to the right places. Trying again!

Is your Kindle up and running? I also have a Kindle Fire HD 8.9 and yesterday I downloaded latest update.bin file (8.4.9) from Amazon and updated my Kindle and later rooted it using the manual method described in http://forum.xda-developers.com/showthread.php?t=2069117 thread. It was total success. Just don't miss a single step from that method.
Actually I had my Kindle (ver 8.4.8) rooted before and Google Play installed with the same method but I was having some issues (not because of rooting but because I had been tinkering with the system apps) so decided to update to overcome those glitches. I installed RootKeeper from Google Play and told it to protect my root access during update process but this crap could not. After update I lost my root and now Google Play Store and related services stopped working, as I didn't have root access so couldn't manage to delete their apks from System apps. So I decided to root it again with the same method and I did it, after rooting it again I went to system apps and deleted old apks of Google Play and other related apks. Then I agin installed Google Play using the automatic method mentioned in above thread.
Sorry if this story is irrelevant but I just wanted to share my experience so any one searching for something could find a clue from it. One thing is confirmed here, KFFirstAid can easily install Google Play after 8.4.9 update and the above mentioned manual method can root it successfully. I am not sure about automatic method though.

you have been very usefull! Thx...but, i still can't root with any method
Can i ask you for some help (i've actually the 8.4.9 version) in private?

Already tried this. It works partially only once it is fully done rebooting the kindle fire is running so slowly as to be unworkable for any thing. Also the lock swipe etc looks torn inhalf. At this point i have to use recorvery to get it to respond properly. I need to root or change rom out right (preferably) But the fast boot commands do nothing. Tried getting it to show up as gem device and use the other drivers that are suppose to let me enter fast boot by a fastboot command. It does not seem to work.
So after trying the method in post 9 again i need to recover to factory again. As it is running extremely slow

Stunts what is the best surefire way to downgrade? My previously rooted kindlefire hd 8.9 just got ota updated to 8.4.9. I had disabled ota i thought but it would seem it wasnt. Now i can not reroot it properly. I want to just go with a custom rom and be done with this mess. I do not have a fastboot cable. But it would seem there are ways around that such as the fastboot -i etc etc how ever i tried that and it did not work (including getting the drivers to the jem. I think i may be missing the chance to get the update drivers bit done intime (not sure here). At any rate help!!! heh
Again what i want to do
Downgrade to easiest rom ver to flash from to a custom rom using what ever meathod is the most effective minus fastboot cable. also recommendations on rom to use are very welcome.

Is your Kindle up and running? I also have a Kindle Fire HD 8.9 and yesterday I downloaded latest update.bin file (8.4.9) from Amazon and updated my Kindle and later rooted it using the manual method described in http://forum.xda-developers.com/showthread.php?t=2069117 thread. It was total success. Just don't miss a single step from that method.
Actually I had my Kindle (ver 8.4.8) rooted before and Google Play installed with the same method but I was having some issues (not because of rooting but because I had been tinkering with the system apps) so decided to update to overcome those glitches. I installed RootKeeper from Google Play and told it to protect my root access during update process but this crap could not. After update I lost my root and now Google Play Store and related services stopped working, as I didn't have root access so couldn't manage to delete their apks from System apps. So I decided to root it again with the same method and I did it, after rooting it again I went to system apps and deleted old apks of Google Play and other related apks. Then I agin installed Google Play using the automatic method mentioned in above thread.
Sorry if this story is irrelevant but I just wanted to share my experience so any one searching for something could find a clue from it. One thing is confirmed here, KFFirstAid can easily install Google Play after 8.4.9 update and the above mentioned manual method can root it successfully. I am not sure about automatic method though.

This worked for getting root back, but didn't initially work for the Google apps. It looks like Amazon filled the file system /system leaving no room for the apps. Since I don't use Text To Speech, I removed /system/tts/ivona/vox_en_us_salli22i which is 100+MB, freeing plenty of space for Google apps. I saved a copy to /sdcard just in case. I recommend saving a copy of system.img first, since my first attempts at removing files deleted the apk, but didn't free the space and I had to do a restore once.

Full Manual Root - Kindle Fire HD 8.9 System Version 8.4.9 on Ubuntu Linux 14.04
Hi Guys,
If none of the usual methods work, here is a method for rooting Kindle Fire HD 8.9 with the new 8.4.9 system version. It was written for and tested on Linux, but should work on Windows as well.
Requires Linux and "DOS" scripting knowledge - particularly if anything goes wrong. If you are not familiar with linux shell, please do not try!
USE AT YOUR OWN RISK!!!
I was struggling a whole day with rooting my Kindle Fire HD 8.9 with the 8.4.9 stock rom. I use Linux (Ubuntu 14.04) and don't really have access to Windows. I've tried several methods, including several versions of the Bin4ry method, but the result was:
a) nothing happened at the end,
b) the system was hell slow, but did not get the root prompt/access.
Finally I've managed to root with a full manual - no script running - method. It was based on Bin4ry v18.5.1 root: the tools were uploaded to the kindle from the package, and the rooting steps were based on the RunMe.bat (manually entering step-by-step). It requires an installed adb on the linux machine (I have it from an Android SDK install)!
Sources:
http://forum.xda-developers.com/showthread.php?t=2277105 : I've started from here. I recommend to read this before starting the process.
http://forum.xda-developers.com/showthread.php?t=2069117 : "C-2) The next steps are used to Root the Kindle - Alternative Method (Manual Version)"
http://pocketnow.com/2012/10/10/root-without-unlocking : for understanding the exploit
Requirements:
1. Install adb on the linux machine.
2. Download Root MANY ANDROID 32-bit!(Dropbox): https://dl.dropbox.com/u/54456659/Win32.zip and extract.
Rooting:
The steps are based on manually entering the commands of the "1)Normal" method of the RunMe.bat:
1) In a terminal change to the directory where Win32.zip was extracted and enter:
Code:
adb push stuff/busybox /data/local/tmp/.
adb push stuff/su /data/local/tmp/.
adb push stuff/Superuser.apk /data/local/tmp/.
adb shell chmod 755 /data/local/tmp/busybox
2) Restore the fake “backup”. Note: _do not click restore on your Kindle device_! Just enter the command into the command prompt on your PC and press the enter key:
Code:
adb restore fakebackup.ab
3) Run the “exploit”:
Code:
adb shell “while ! ln -s /data/local.prop /data/data/com.android.settings/a/file99; do :; done”
(It will display a lot of "link failed File exists" lines)
4) Now that the “exploit” is running, click restore on your device.
5) Once it finishes, reboot your device. Note: Don’t use your kindle yet, this exploit reboots into emulator mode which will be laggy with a flickering screen (or no display at all). This is normal.
Code:
adb reboot
6) Once rebooted, open a shell:
Code:
adb shell
Check: Once you do step 6, your should have a root shell (your prompt should be #, not $). If it’s not #, start again from step 2.
7) Continue with the steps of the RunMe.bat - now entering the commands in the root shell:
Code:
/data/local/tmp/busybox mount -o remount,rw /system
/data/local/tmp/busybox mv /data/local/tmp/su /system/xbin/su
/data/local/tmp/busybox mv /data/local/tmp/Superuser.apk /system/app/Superuser.apk
/data/local/tmp/busybox cp /data/local/tmp/busybox /system/xbin/busybox
chown 0.0 /system/xbin/su
chmod 06755 /system/xbin/su
chmod 655 /system/app/Superuser.apk
chmod 755 /system/xbin/busybox
rm /data/local.prop
reboot
Done .

The Method described above didn't work for me.
Tried to do it step by step but the exploit part is not working, gives me a syntax error.
Then i used runme.bat and the exploit seems to work (slow reboot, scrambled kindle logo) but root isn't working properly afterwards.
It's kinda half-rooted now, with SuperSU working and displaying "granted root access..."-messages but if i try to install the play store i'm stuck.
ESexplorer is in root mode, mounted system R/W but when i try to move vending.apk to system/app it fails. No root access it seems
Opening SuperSU results in a failed update process....
Any kind of help is deeply appreciated...

Fixing that syntax error

This method worked for me! I also got a syntax error the first time arround but I fixed it by splitting this command (adb shell "while ! ln -s /data/local.prop /data/data/com.android.settings/a/file99; do :; done") into 2 separate command 1) adb shell, 2) while ! ln -s /data/local.prop /data/data/com.android.settings/a/file99; do :; done
After taking away the quotes it worked exactly as described!

Need help installing TWRP

Ok I have a firetv 2 and am already rooted but I don't really understand on how to install the recovery tool. I assume that I can just install it without having to run a custom rom or am I wrong. I don't really want to have to reset my whole FTV if I don't have to. Is there a link with a how to on just installing TWRP? Thanks

Ok so the best place for what your looking for is here -
http://www.aftvnews.com/how-to-root-the-amazon-fire-tv-2/
Give aftvnews the credit for this guide
& underneath is the guide, credit for recovery & guide this is to rbox
Installation
You can copy the files to /sdcard, a USB storage device, or an sdcard. I will be using /sdcard in the instructions, but you can replace it with /storage/usbotg for USB or /storage/sdcard1 for an sdcard.
Copy the zip file to your destination.
Connect adb
Code:
adb connect IPADDRESS
Open an adb shell
Code:
adb shell
Run the zip file (replace vX with the actual version you downloaded). This will automatically run su, so make sure to accept the prompt if necessary.
Code:
sh /sdcard/firetv2_recovery_vX.zip
Reboot
Hope this helps if so press than thanks button

Did you ran the su command after rooting? If so have you agreed to its permissioned when asked (pop up screen that will appear on the screen)?
BTW, Instructions above reflect installing zip file from sdcard., you need to push this zip file to the sdcard dir first.

Do you have root? Are you using the latest version of adbfire? Maybe this thread Is not the best place to ask, try the adbfire thread & ask the Dev himself?

Thanks for your help. I did have root but I just decided to just start fresh and install a new rom. Looks like everything's working now.
