No KNOX Exynos root method via engKernel. Exynos testers needed. - Samsung Galaxy S7 Guides, News, & Discussion

Looks like some folks are claiming a no KNOX exynos root method, just like the one available for the SnapDragon phones.

Here's a complete package for ALL S7 EXynos models with clear instructions in the 0_ReadMe.TXT file.
Also, made a Root.BAT mod which should disable the "Security Notice" and FOTA (test and report back).
Highly recommend starting on a fresh stock flashed, and/or data/cache factory resetted phone.
Not responsible for any consequences, so make sure you have a full stock firmware just in case something goes wrong.
Big thanks to PrinceComsy, Br3w3r, and Chainfire for making it all happen.

Also, enable ADB and OEM Unlock under Settings > Developer Options (may need to do the 7 tap method on Build Number, search for it).
When running the batch file, try running it quickly back to back as soon as you see the Samsung logo on the bootup screen, even if it fails just keep re-running it till it's finally successful.
It's a known issue, where ADB is only active for short period of time. Timing is everything

I don't mean to steal Billa's work, but I think this needs to in its own thread so we can work specifically on this root method. Billa if you want to make your own thread, I will delete this one.
I'm curious if anyone can confirm this method works?
UPDATE: I did manage to get the engKernel installed. It bootlooped for a while but once I went into recovery and actually did a full wipe, it booted after a few loops and a long wait. I can see it is a little buggy and laggy. Hopefully some of the fixes to repair the kernel will make it faster.
Unfortunately, the script that actually installs supersu is bugging out. It worked once part way, but for the most part it hangs on copying the su binary over, eventually giving a "protocol error" I think this may have something to do with my ADB setup. I've read it might have to do with USB write perms but mine should be good. I'm curious if running the script as admin will fix it but I haven't been able to get that to work, it just exits.

Are you running on Windows? If so maybe I could help you out with that script just closing.
Right button click on your desktop and go to New -> Shortcut
For the Location type in "cmd" without the quotes
Name it whatever you want, I personally like naming it Elevated Command Prompt, and click finish
Now you want to right button click on the new shortcut you made, and go to Properties -> Advanced and check the Run as Administrator box and apply that setting
Open up the new Command Prompt shortcut you created on your desktop, UAC may prompt if you want to allow it, go ahead and accept it.
Now you will want to navigate to the directory of where your .bat file is located
-For example, if your command prompt directory is located in C:\Users\whateveryourusernameis (Should be in C:\Windows\System32 when granted Administrative privileges) and you need to navigate to C:\adb then you will have to type in "cd C:\adb" without the quotes.
From there you will want to check that you are in the right directory and that the file is there
-Type in "dir" without the quotes and hit enter. It should give you a list of file names in the folder you are located in, verify that the .bat file you are looking for is there, if not then you're not in the right directory and will need to make sure to go to where it is located.
If you were in the correct directory then all you have to do now is run the batch file from the command prompt window
-Type in "root.bat" without the quotes and hit enter. If there is a problem, the error message will stay up and not close itself out like it probably has been doing.
If it fails, all you will need to do is hit the up arrow on your keyboard and it should say "root.bat" again and hit enter.
Give that a shot and let me know if that helped.
Also, sorry if it's too descriptive, I don't know anyone's level of knowledge behind a computer screen so I wanted to make sure no matter the skill level, anyone can follow these directions.

Thank you so much dude! That was good advice and I really appreciate the writeup for anyone else who comes along. Realizing that the kernel tweaks from the snapdragon kernel probably wouldn't work on exynos and that having to use the engineering kernel will probably never be very satisfactory, I went ahead and tripped my KNOX by installing a custom recovery and ROM.
I just wanted to explore this no KNOX root method as much as possible and see if it can be made mature for the next person who comes along, since I really don't think it is yet.

The tweaks may work but it will never be the best experience because it's an engboot, unfortunately. Some people prefer it over non-root anyways, and I'm starting to feel the same. Tripping your Knox probably won't mean anything for where you live anyways, enjoy root without decreased performance on your phone!

so this will reduce performance on my exynos device? that sucks . I'm rough on my phone and need the warranty just in case, but need root for things like sixaxis

Well, that and losing the warranty and any resell value of your brand new expensive phone... I'm still figuring out how to remove the bloody shutter sound on my 930S without voiding the warranty. As of now, there's no method for even a temporary root just to access the system sound files. I guess we'll have to wait for a knox-neutral root until the warranty of this thing ends anyway....

Pretty sure the point of this root method is that it doesn't trip know, thus negating that worry

Well, I have posted that just as a proof of concept root without tripping Knox, leaving all testing up to you guys.
Installation is a bit tricky, gotta get the timing just right while the ADB port is open for a short time during the bootup sequence.
With careful tweaking it can be adjusted to give a fairly smooth performance, read the S7 QC/Qualcomm threads.
Happy hacking

I agree that with tweaking, this may become a very viable root method. I just worry that everyone who would be working on this as a dev has already knox 0x1 their phones
I guess we will see what the masses come up with.

Alright, that's exactly what happened to me. I also get a protocol error message sometimes. So there is definitely something up with the ADB file push command. Maybe someone who knows more about ADB can get that working.

so i did everything and it looks like i even got supersu installed, but it's not actually rooted... At least not according to rootchecker
---------- Post added at 09:44 PM ---------- Previous post was at 09:28 PM ----------
welp, i just checked via download mode and yup, it tripped knox... darn Positive is I can do a full root of my phone now

Tested this on my FD, didn't root the phone but didn't trip KNOX either. I've sent a logcat to the author; probably isn't much help but it's something, right?
Going to root my phone the traditional way though after this, sorry!

Has anyone successfully tested this?
I'm not rooting until this is confirmed working - happy to contribute towards a bounty if someone is working on this

i m wondering if anyone succeed this ?

I read you can turn off system sounds and that seems to work. You can also fast toggle sound in the pulldown prefs. Seems to work fine.

Nope - there are different levels of bullcrap and the 930S seems to beat it all.. The camera app doesn't care at all about the system sound settings, it always zaps you in your face...

How to confirm I have unrooted?

Okay unfortunately 5 mins after rooting my phone I noticed my replacement Vibrant has a bad screen. I used the one-click program to root, so I did the same thing to unroot. I downloaded ROM Manager after I unrooted to confirm the phone was unrooted and ROM Manager seems to think so (it told me to root my phone).
However, I am wondering if there is any way to *confirm* my phone has been unrooted (i.e. manually look for the root files and make sure they are not there)? I ask because I reset my phone to factory settings after unrooting, but updated.zip and chromemod folder were still present when I looked under files, which sort of scared me into thinking T-Mobile may be able to detect I had rooted.
Thanks for all the help and wish me luck for my *third* Vibrant.

rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su
you could also do it from adb.
rhcp0112345 thanks for the app but I think the su way sounds easier.
Thanks zephiK and d_bot! I did the su thing and got a "su not found" error so I guess I am good.

Well, I know there will probably be a lot of people freaking out on me, but from how I use my phone the only use I've had so far is using cachemate to clear cache, and possibly modding the look of the os. I personally used to it to remove the annoying tmo boot and shutdown sounds/video.

Welcome to Android 30Glock
the main benefit of rooting is to be able to remove bloat-ware. Bloatware plagues the vibrant. Besides that there are other things you can do like custom roms(not many for the vibrant but they will come), with custom roms comes custom themes, also you can increase you cpu frequency. There are a few awesome apps out there that require root (Titanium Backup).
Basically think of it as you have just been given a new windows machine at work, and the admin gave you User permissions, so yeah you can do some cool stuff, but to really get in and have some fun you need admin permissions. To root/unroot this phone it is jaw dropping easy! Thank you samsung. Thank you DEVS!
Install Root Explorer and try to navigate to your system folder.

Step by Step for Rooting Rogers Captivate (I896)

Hey Guys
So one of the biggest questions I have seen in the last couple weeks since the Rogers captivate was released is how to root. I figured I would write a nice tutorial for everyone to make it easier!
Method 1: SuperOneClick
This is the easiest way, however most people have not been able to achieve root using this. Try this first if no luck move to method 2. Instructions on how to root using SuperOneClick can be found here
Method 2: Manual Root using ADB and Terminal
This one takes more time and not as easy to do as you have to do everything manually. But haven't heard of any problems with it yet
Step 1: Install <PDANet> Drivers. Just download the file and install. Select Samsung drivers. No need to actually install PDAnet on the Captivate you just need the drivers from the install. Follow the instructions with the installer to properly install the drivers.
Step 2: Download <Andriod SDK>.
- Extract the Android SDK .Zip file to C:\AndroidSDK (this should name the new folder created AndroidSDK in the C directory.
- Go to your start menu and search cmd or click run and type in cmd to open command prompt
- Type the following into command prompt, hitting enter at the end of each line
cd C:\AndroidSKD\Tools
adb devices
- You should see a serial number pop up. This is the serial number of your phone. This means ADB is set up
Step 3: Download <RageagainsttheCage Rooting Files>
- Extract them to the c:\AndroidSDK\tools\ folder. HAS TO BE IN THIS FOLDER FOR THE FOLLOWING COMMANDS TO WORK
Step 4: Unplug phone if it is plugged in. Then, on the phone, go to Settings > Applications > Development and make sure USB Debugging is Checked ON.
Step 5: Plug phone back in to computer. Make sure SD are not mounted
Step 6: Reopen Command prompt if not open. In the command prompt enter the following, pressing enter at the end of each line
cd c:\androidsdk\tools\
adb devices
adb push Superuser.apk /sdcard/
adb push su /sdcard/
adb push rageagainstthecage-arm5.bin /data/local/tmp/
adb shell chmod 0755 /data/local/tmp/rageagainstthecage-arm5.bin
Step 7: On the phone, go to Marketplace and download Terminal Emulator
Step 8: Leaving the phone plugged in, open the Terminal Emulator on the phone. Type the following, pressing enter at the end of each line
cd /data/local/tmp
./rageagainstthecage-arm5.bin
Step 9: WAIT. It will take a full minutes for the rage root to install. When finished you will see "Forked Childs". DO NOT DO ANYTHING TILL YOU SEE THIS. Terminal will allow you to type as it goes back to $ while it is installing BUUT DO NOT DO ANYTHING JUST WAIT(Cannot stress this enough)
Step 10: once "Forked Childs" appears, exit the Terminal App, and then reopen it. Instead of $ you should now see #. If not redo Step 7. Otherwise continue.
Step 11: Type the following hitting enter at the end
cat /proc/mounts
This should bring up a list (Easiest to view in landscape mode. Look for the following
/dev/block/XXXXXXXXXX /system YYYY ro 0 0 (the XXXXXXXXX part should be different depending on which device you have. The YYYY part will either be; ext2, ext3 or yaffs2 or something similar. )
My YYYY was rtf , not sure if it will be the same for everyone (though i assume it is)
Step 12: Now in the terminal window, using the info from above, enter the following, hitting enter at the end of each line (Be sure to enter spaces where needed as below)
mount -o rw,remount -t YYYY /dev/block/XXXXXXXXXX /system
cat /sdcard/Superuser.apk > /system/app/Superuser.apk
cat /sdcard/su > /system/bin/su
chmod 4755 /system/bin/su
mount -o ro,remount -t YYYY /dev/block/XXXXXXXXXX /system
exit
Step 13: Close terminal window if still open. Check your app drawer and, assuming everything was completed properly, you should see Superuser. If not redo Step 12, again watching for spaces and using the correct info from Step 11.
ACKNOWLEDGEMENTS
I, in no way shape or form, came up with the above method or tools. This method was modified from and composed from the method decribed over at Theunlockr.com for ease of use and to root the Captivate specifically. I big thanks go out to those guys!

I am not responsible for any damage doone to the phone or its file system as a result of this tutorial. It is for educational purposes only. You have been warned!
THANK YOU!
No other method was working for me (not SuperOneClick, not these ADB instructions). Sure enough, using Terminal Emulator, I was able to get #. I wasn't able get this through adb, nor was I through SuperOneClick (infinite loop @ "mount" command).
I noticed a few things:
-When I compared filesizes from your provided Rage Root files, to the ones that were included in this thread (which also come with SuperOneClick—and which I was unable to get working), I noticed major differences. This gave me hope!, as I'd tried everything else that I knew how to prior to this point.
-My "XXXXXXXXXX" was actually only 4 characters: "stl6".
-My "YYYY" was only 3 characters ("rfs").
-SuperUser showed up on my applist without even requiring a reboot.
THANKS AGAIN
I shall now attempt to apply a lagfix; I will report back with results.
--Bah: no luck. RyanZA's OCLF V2.2+ returns error:
Could not mount /dev/block/mmcblk0p2 onto /dbdata/rfsdata: mount: No such file or directory
--OCLF V1+ returns error:

Yup same problem here. I was able to root it manually a few days ago, but have as of yet been unable to lag fix it.
Strange. After I rooted I had no problem using RyanZa's Lagfix. Your still using the stock rom after rooted correct?

Correct. I've tested out quite a few apps from the market, though.
When I mount my device, I notice that there are some files on my internal SDCard:
-su
-Superuser.apk
-nv_data.bin
-busybox (why is this there, I uninstalled that)
-update.zip
...and some folders:
-layar
-twc-cache
-Android -» data -» com.cooliris.media
-Android -» data -» com.google.android.apps.maps
-svox
...These all have subdirectories.
Not knowing what a default internal SD directory ought to look like, I wonder: Could any of these be causing a conflict? I read that some said not to have any apps installed on the SDCard while trying to mess around (with ROMs, I think), so I tried removing what I could, and then rebooting (and some folders respawned), and reapplying the fix—no dice. I've since replaced all of the folders and the files.
Stock rom here as well.
Hrmm not quite sure why lag fix isn't working for you guys. Just a quick question, in RyanZa One Click, is "Un-Root Device" green?
I still have no problems applying RyanZa Lag Fix to my Captivate as I had to redo it last night after i switched back to the Rogers stock rom after testing Cog 2.2. My guess, and it is just a guess, is that the root never applied properly. Have you tried rerooting the device?

Thought I might give you some info as well since i've been messing with mine for about a week now. I was able to root the device, oneclick did not work originally for this and I used ADB method similar to what you had here. After this I went for the lag fix, everything was green like it was supposed to be, installed the ext2 tools no problem and then get the same error about unable to mount when applying lag fix.
At this point I used OCLF to unroot the device and it did, I then used the oneclick to re-root which it did this time, in terminal I can su properly and again all the tools are green in OCLF. Tried to lagfix and failed again so I started making some changes manually based on the error messages that were out put. Created the folder it was trying to mount to for instance and then set the permission to this to 777 that would allow world write access, this allowed it to create the new partition in ext2 but when mounting the loopback device it fails saying it doesn't exist (which it doesn't I looked) so while I did get a bit further the lag fix still fails. I would gladly apply the lag fix manually through the terminal if I knew everything that was being done to re-format the partitions for ext3 but I can't seem to find that info anywhere.
Next best thing I would guess is to install a stock rom from rogers from someone else and see if there are any differences, I'm guessing based on the devices in the /dev folder that there are more then one image on the devices some set up more similar to AT&T that the lag fix will work on.

Try the stock rom in the main Rogers Captivate forum. It is one i used to go from Cog 2.2 back to stock and it applied the root and lag fix without a hitch. Give it a try and let us know!

Happen to have a link right to the forum? so many threads to search through...
I'm new to the whole android thing though I've been working with linux for years but its a bit of a learning curve coming from a blackberry.
also what are you using to flash your device?
I'm having the same problem. Let me know if you somehow fix it.
Sent from my SAMSUNG-SGH-I896 using XDA App
I was finally able to get my last night.
Turns out my first root attempt was a failure. I had to unroot via an update.zip method as i did not have the permissions to remove the files from terminal.
Once unrooted i then did the update.zip method for the I897, and modified the script to look for I896 instead. It worked flawlessley. I am now getting the pop-up asking for root permissions. I had never seen it work previously.
I was then able to install OCLF without any problems. (and it popped up asking for root)
I am now rooted and lag fixed. Previous quadrant score was at 860's and i pulled a 2285 last night after the OCLF.
Can you please tell us how to modify script and how to flash back to stock..I need to return my phone and superuse app wont go away after unrooting and factory reset

Well i cannot help you flash back to stock as i don't quite know how to do that yet myself. But i can help you unroot, re-root, and lag fix.
I have found the files again and uploaded them to rapid share with the necessary modifications.
Download THIS FILE and once downloaded, rename it to update.zip Be careful not to name it update.zip.zip by accident.
Place the file into the root of your sdcard.
Shutdown the phone with the power button, or pull the battery out and put it back in.
Enter recovery mode:
While holding the volume up and volume down buttons press and hold the power button until you see the white text that says SGH-I896, then release the power button only.
When in recovery mode use the volume down key to highlight reinstall packages, then press the power button. It should say completed and reboot the phone.
Once the phone has rebooted, do the exact same thing again, only use THIS FILE instead. Dont forget to rename the file again!
Then install the OCLF from market. Install the EXT2 tools first. Then run the lag fix installer.
I assume you already know how to enter recovery mode, but this way someone else searching for a fix will have all the info at their disposal here.
EDIT!!!
Some mirrors for the files

Hi all i am very lost here....i have tried for hours the last few days on how to root this i896 with the super one click method with no luck....anyways i was speaking to my brother earlier and he has done it with his bell vibrant no problem....anyways what i want to know is what is the purpose of rootindg the phone? I thought it was for downloading 3rd party apps or whats the purpose for superuser? The reason why i am asking is that i can download 3rd party apps already...i allow them on my application settings and download a app downloader and works fine? Im lost someone please help.

Take a look here. It answered alot of my questions.
http://www.androidcentral.com/rooting-it-me-some-qa
Also, if you only follow the second half of my post above you should be able to root it as well.
Thanks deacfire! The one click wouldn't work for me but the second method did.
I am having a really annoying problem though. The superuser.apk that you included just gave me a black screen. So I updated it to this one: http://forum.xda-developers.com/showthread.php?t=682828&highlight=no+apps+in+list
Which is newer. But now it just says "no apps in list". Tried installing it from the zip, tried from the market no different.
I do have apps that require superuser: ROM Manager, Root Explorer, Adfree. They all work, also have titanium backup but its is telling me it needs root access.
How can I fix this, it is a major issue.
EDIT:Thanks impulser91!! That work and was SUPER easy! Should probably get posted in the original post.
when i copy update.zip into the /sdcard and then try hitting reinstall packages, it results in an error and aborts. any suggestions?
Nevermind....it worked MUAHAHAHAHAHAH LET THE FUN BEGIN!
Sweet, 2 users. Not bad for under 10 posts
I'm glad its working for others. I had one heck of a time finding the right combination of files and process's for the I896. I am an IT professional and it took me a few days of fumbling around all the I896 and I897 posts.
Anyways, glad to hear it worked, and i hope other people find it useful as well. I will keep the originals, so if the links go down someone just PM me and i will load them somewhere else.

I could just about kiss you.... but I won't
Thanks for the update files they worked like a charm. I had a similar issue where the device didn't seem to be properly rooted, though it didn't give me any issues with most things when applying the lagfix it would die.
applied both your unroot and then root and it worked flawlessly the first time, lagfix then ran with no issues and my quadrant scores are 2250 now.
Not sure what you did exactly, I've tried rooting from update.zip from oneclick and neither worked I ended up rooting with the ADB and though it seemed to work it apparently did not.
Thanks again

[HOW TO][UPDATED GUIDE] Unlocking & Rooting your XOOM!

UPDATED XOOM FLASHING GUIDE 02/02/12​
I recently bought a US Xoom MZ604 and had trouble flashing it initially. I came to a realization that the newer models of Xoom reinstalls the Stock Recovery after you flash a custom Recovery (eg. CWM, Rogue Recovery etc). This is uber frustrating for newer Xoom owners, especially those who are new to the flashing community, simply because you don not know exactly what's going on.
Also, I could not find any proper, full and updated guide to flashing your Xoom. So i decided to take the initiative to do so.
WARNING: I DO NOT TAKE ANY RESPONSIBILITY IF YOUR XOOM TURNS INTO A USELESS BRICK. BY FOLLOWING THIS GUIDE, YOU WILL VOID YOUR XOOM WARRANTY WITH MOTOROLA. YOU HAVE BEEN WARNED TO EXERCISE CAUTION WHILE FOLLOWING THIS GUIDE. STRICTLY FOLLOW THIS GUIDE AND I ASSURE YOU, NOTHING WOULD GO WRONG.
In order to follow this guide, you need fundamental knowledge of ADB and Fastboot for Android. Search around the forum for this knowledge.
STEP 1: Obtaining Required Materials
a.) Download the latest version of Android SDK from HERE and install it into your the root of your C: drive.
b.) Download the latest version of Java SE from HERE and install.
c.) Download and Install the latest version of Motorola USB Drivers from HERE.
STEP 2: Unlocking your Bootloader
What is a Bootloader?
In literal terms, bootloader is code that is executed before any Operating System starts to run. The concept of bootloaders is universal to virtually all Operating systems that inculcates operating systems on your PC, laptop, smartphones, and other such devices. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment. As the bootloader kicks off before any piece of software on your device, it makes it extremely processor specific and every motherboard has it’s own bootloader. Source: http://www.addictivetips.com/mobile/what-is-bootloader-and-how-to-unlock-bootloader-on-android-phones-complete-guide/
Click to expand...
Click to collapse
1.) Make sure your Xoom is turned on. Connect it to your PC via USB.
2.) On your PC, open up File Explorer and Browse to:
C:\Android\android-sdk\platform-tools
Click to expand...
Click to collapse
3.) In that directory, make sure nothing is selected, SHIFT+Right Click into empty space and select "Open command window here".
4.) Command Prompt will open up. Type the following command:
adb reboot bootloader
Click to expand...
Click to collapse
Your XOOM will reboot into the bootloader showing "Starting Fastboot Support Protocol".
6.) Type the following command into the Command Prompt to unlock your bootloader:
fastboot oem unlock
Click to expand...
Click to collapse
7.) Read the warning and follow the instructions on the Xoom Tablet itself from this point onwards. Use the Volume Down key to navigate to 'Accept' the agreement and press Volume Up to select.
8.) Once selected, your Xoom will now unlock and format itself, meaning, all data will be cleared and you will back to a factory rest.
9.) Reboot your Xoom with the following command:
fastboot reboot
Click to expand...
Click to collapse
10.) Exit Command Prompt.
STEP 3: Rooting your Xoom
1.) Download the latest version of "Universal Xoom Root" from this thread. Place the .ZIP file into the root of your SD card.
2. Download this version of "ClockworkMod Recovery - Modified for Motorola Xoom" and place it into this directory:
C:\Android\android-sdk\platform-tools
Click to expand...
Click to collapse
This will your new Recovery. MAKE SURE THAT IT IS IN .IMG FORMAT.
2.) With your Xoom still connected to your PC, type the following commands into Command Prompt (open up using the same method as STEP 1) to install your new Recovery.
adb reboot bootloader
fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
Click to expand...
Click to collapse
3.) Once you have verification on your device that this has been flashed, reboot your device by holding volume up + power.
Then 3 seconds after you see the Motorola logo, hit volume down. You should now see "Android Recovery" in the top left corner. Hit volume up to boot into recovery. If you miss this window and somehow end up booting your Xoom normally, repeat from STEP 3, section 2 onwards again. DO NOT CLOSE THE COMMAND PROMPT WINDOW.
4.)To root your Xoom, please perform the following:
"install zip from sdcard" -> "Choose zip from sdcard", then select the Xoom-Universal-Root.zip file you downloaded.
Note: use the volume buttons to navigate and the power button to select
Click to expand...
Click to collapse
After the root flashes itself, DO NOT REBOOT YOUR XOOM!
5.) Now you have to rename the 2 notorious files, that reinstall your Stock Recovery over CWM, into a format that is unreadable by the bootloader. In the already opened Command Prompt, type the following commands:
adb remount
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old
Click to expand...
Click to collapse
6.) Reboot with CWM. Let your Xoom boot normally.
To test whether the root and flashing of CWM has been successful, type the following into your command prompt:
adb reboot recovery
Click to expand...
Click to collapse
If you are able to access the new Recovery, CONGRATULATIONS, you have successfully UNLOCKED & ROOTED your Xoom.
I would like to thank the Xoom Android community for your valuable commitment to into Xoom Android Development. Without you guys, the Xoom wouldn't feel much powerful in terms of usage. Also, I'd like to extend my gratitude to okantomi for his help when I first started out.
Those those experienced users of Xoom, please kindly help the newbies like me answer their questions in this thread. Could I also request the mods to sticky this thread for reference.
NOTE: For users who would like to revert to the original recovery, type the following into ADB: (tip provided by wontoniii)
adb shell mv /system/recovery-from-boot.p.old /system/recovery-from-boot.p
adb shell mv /system/etc/install-recovery.sh.old /system/etc/install-recovery.sh
adb reboot

1.) [Recovery] ClockworkMod 3.2.0.0 (R4c) Modded for Internal media [UPDATED 10/6]
2.) [ROM][Nightly][ICS] Team Eos WiFi Nightlies (Wingray/MZ604)
3.) [Root] Universal Xoom Root - ANY XOOM ANY UPDATE
Just my opinion, I would not recommend to everybody the step3/point6 as you do it...
I would just do something like:
adb remount
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old
Click to expand...
Click to collapse
This can be easily reverted with:
adb remount
adb shell mv /system/etc/install-recovery.sh.old /system/etc/install-recovery.sh
Click to expand...
Click to collapse
In case someone could want the old recovery back without flashing anything

I believe your method is better, at least there's still a recovery to revert to in case something goes wrong. I'll add it to the guide. Thanks for the suggestion!

Thread moved to General.
This seams to be a good guide can anyone tell me if it works it is more detailed than the other guide ???? and why was it moved to general
This guide is great and easy and very updated i dont know why other people dont use it. One thing tho you should be more clear on how to reboot into recovery tell them to press volume up + power then let go then wait three seconds and after logo and press only the volume down
Having a problem with using your guide
Ok, I'm a noob. I am probably missing something simple. When I type "adb reboot bootloader" at the command prompt it says "Device not found." My Xoom is connected via USB (Same cable it came with). Xoom appears in my explorer window I can browse through the files; I even transferred files to the SD card. It is just not detected from the command prompt window when I start the unlocking procedure. Any assistance would be appreciated. Using Xoom 4G, Android 3.2.4; Windows 7
Make sure that adb debugging is checked. You can find this under Applications > Development settings.
Before you type, check if your device is listed
Code:
adb devices
This should list your device.

Superb Guide!
Many thanks, I spent the best part of a day trying various methods but found this to be the most n00b friendly
1 point it may be worth adding is to use adb you must have java installed on your pc, without you get error "adb.exe is not a valid win32 application"
first time root/flash rom question
Hi all..to start with sorry if im asking in the wrong place. I have a stock Xoom with an unmodded ICS I also own the Bionic. Also I have never rooted or flashed anything so I am a super noob (soon to change though).
I wated to be able to have USB host functionality and be able to have SD card read/write assess so last week I started searching Google which led me to this wonderful sight of great help. There might be too much help because after tons of reading there is more than one way to do what I want. Can someone please point me in the best way to root and which rom I should use that will give me the least about of trouble.
Thanks in advance

Ihave similar story m8. I spent the majority of yesterday reading and learning how to root. This is by far the easiest guide to follow to ulock and root your xoom.
I just want to correct a small error here.
In Step 6 of Step 3, you say you want to check and make sure that the new bootloader is on there correctly.
I think you mean to say check and make sure the new "Recovery" is on there and the adb command would be "adb reboot recovery".
Am I wrong? If so, please disregard.
At which point do I back up data already on Xoom? Will there be any data loss?

You have to backup your data before unlocking the bootloader, which is the VERY FIRST step.

Yes you are right. Thanks for pointing that it, it could have confused some. I'll rectify that right away.
Ok so I have a question about this rooting process and I haven't seen the answer yet. My question is will this process work weather your xoom is running ICS or HC?

Rooting Gingerbread 2.3.6 (4.5.141) - The Complete Guide

Having just purchased another Atrix that was running stock Gingerbread 2.3.6 (4.5.141), I was frustrated by the lack of a complete rooting guide and appropriate files. There is a guide in this forum (Link) which is based on an article from Android Advice (Link), but I noticed that both lack a lot of basic information for the inexperienced user. Also, the zip file available from Android Advice was missing a key file (Superuser!). So, I made a guide.
This may look complicated, but is super easy. If you don't feel comfortable using this method, you can use this automated tool (yes, it works on 4.5.141). It won't be as satisfying, or even feel good. You won't learn anything, but you will be rooted. Download tool here (link in OP is broken).
Pre-work:
1) Read the xda Atrix Beginners Guide (then read it again)! (Link)
2) Download and install 7zip. (Link)
3) If they are not already installed on your PC, download and install the Atrix drivers for Windows. (Link)
4) Download the attached files (sorry, had to break them in to two files due to forum size constraints). Create a new folder on your hard drive named "Android" (c:\Android). Extract both attached zip files to this folder (all the files need to be in "Android", not in a sub folder).
5) On your phone go to Settings, Applications, Development, then tick USB Debugging.
Notes:
Do not type quotes.
After each command hit enter.
Be mindful of spaces.
You can simply copy each command and paste in to the command prompt.
If you encounter any errors after entering a command, just ignore and keep going (assuming you entered the command properly).
Work:
1) Attach your phone to the PC via USB. In the USB settings make sure USB Mass Storage is selected.
2) Reboot phone while holding volume down until you see "fastboot".
3) Press volume up to initiate fastboot.
4) On your PC click the Start menu, then in the search box type "cmd"
5) In the command prompt type "cd c:/android"
6) "fastboot.exe flash preinstall preinstall.img"
7) "fastboot.exe reboot"
8) Wait for phone to reboot.
9) "adb shell"
10) "/preinstall/dosu". If you get an error (I did), type "/preinstall/su"
11) "/bin/mount -o remount,rw /system"
12) cp /preinstall/su /system/bin/"
13) "chmod 6755 /system/bin/su"
14) "PATH=/system/bin:$PATH pm install /preinstall/Superuser.apk"
15) Reboot phone.
16) On your phone go to your apps and make sure the Superuser icon is there. Open the app, go to settings, then update the SU binary.
17) Open a terminal emulator, then type "su" and hit enter. You should see "#" if you are rooted. Or, download Root Checker from the Play Store.
My phone rebooted itself after step 11, so I had to re-open the adb shell.
I copied and pasted the text from the command prompt for reference (attached).
If I missed anything or have any errors, let me know and I will update the post.
Good luck!
Note: If you experience problems with updating superuser after rooting, try going in to Manage Applications and clear Superuser data. If that doesn't work go to the Play Store and Install Superuser Update Fixer.

Well for me what happen is down at the bottom he has two links for two of the files you need to zip. in one of those, there is a superuser file. When doing the cmd commands at the end you will end up installing the superuser. The best thing to do which really helped me was to download the command prompt text file, that way you can mimic exactly what you see. Hope this helps.

Going to give it a try
I read through everything and think I have somewhat of a clue on what I need to do..LOL. Whatever the results I will post back and let you know. I have had my atrix since it was first released and have never had the time to root it as I cannot be without a phone couldn't take a chance.
I retire soon so hopefully will have more time to get invovled in things as this is a great forum.

Welcome to the wonderful world of messing with your phone!
You really can't harm your phone trying to root it. If you type a command wrong, just re-type it. No worries. There are lots of good guides out there for whatever you want to do. The noob guide (linked on the first page) is a great place to start. And there are plenty of members willing to help.
Let us know how things go!

Don't unlock your bootloader if you think you will want official Moto ICS update (major hard brick risk).

Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks

Hi everyone. As I found out there's root for the G4 but doing this isn't easy especially if your variant is hard to find or has less users. This may result in you waiting for longer than you should. This thread is for those who can take things into their own hands and do it themselves. The tools are available everywhere but I'll give you the best order and steps. I'm using the China LG G4 H818 Dual SIM variant but this method is UNIVERSAL FOR ALL LG G4s.
The process will involve extracting a system image, injecting root and reflashing this image. Most of the steps are effortless and need just copy and paste with keen eyes. Do it slowly. You need an Ubuntu installation for step 2 of this 3-step tutorial. I used universal USB installer and put in on my 8GB USB. Anywhere will do so far as it boots&works. Beware this thread is not dumb-proof but this will not wipe your data or void your warranty if done successfully.
Step 1 -> Getting the proper system image.
Check here and skip to step 3 if you have your rootedsystem.img
>Don't worry because this doesn't require searching. It is from your device. Every device has a system partition and this method will pull it out as an image without root required.
1--Make sure all drivers are installed properly. I'll not be talking about this. We're on XDA not kindergarten.
2--Download the LG_root file or send command file from here and extract it. US Carrier specific check here
3--Put your device in download mode and connect it to your PC.
4--Open(double-click duh) port.bat and make sure to write down the number after com. There maybe different com numbers but choose the com on the DIAG1 line and write down that number. This is important.
5--Hold shift and right-click in any empty space in the extracted folder. Choose open command windows here.
6-- In that copy and paste this
Code:
[FONT=Lucida Console][COLOR=#ff8c00]Send_Command.exe \\.\COM[/COLOR][COLOR=#00ff00][*insert your number here][/COLOR][/FONT]
7--Now you're in send command mode. Nothing looks different on your phone but that's ok. It should just remain in download mode.
8-- On the computer screen in the window you now see #.
9--Now in this post copy the Backup system to internal storage command specific to your device model number. Check in you settings >general >about if in doubt. This is the most important step. Copy the whole line of code. Highlight with your mouse, select everything on the line and copy.
10--You didn't come all this way to fail so do it. Remember it is device model specific.
11-- Paste it in the command window and hit enter. It should take a while so wait until you see#reappear.
12--Now typeLEAVEall in capital letters. Your device will reboot. Check using the file manager if you have a file called system.img in your internal storage. If yes step 2 is next and you did well. If no repeat it and follow the steps properly. Make sure drivers are installed especially windows 10/8/8.1 users. Check device manager
Step 2 -> Root injection.
1--Prepare your Ubuntu USB or virtual machine or computer.
2--Download inject_root zip from here and extract.
3--Copy the system.img from your phone to the extracted inject_root folder on your PC.
4-Reboot into Ubuntu.
5--Here open a terminal.
6--Gain root access on Ubuntu by typing or copy and paste sudo -i
7--You should either be asked for your password which you have to enter or if you used a USB drive like me you'll see the name change to[email protected]
8--Navigate to the inject_root folder by using cd commands. This can also be done by typing cd then [space] then dragging and dropping the folder into the terminal and hitting enter.
9--You'll now see the name in the terminal become longer with the name of the folder in it.
10--Now type chmod +x autoroot.sh
11--Hit enter then sudo ./autoroot.sh
12--If you get any thing like command not recognized or something of the sort use sudo sh autoroot.sh
-That worked for me.
13--If you're successful the name of the file should change from system.img torootedsystem.img
-Please note don't rename the files. Leave them as they are.
14--Now go back to Windows let's finish this.
Step 3 ->Root
1--Transfer the rootedsytem.img to your phones internal storage.
2--Put your phone in download mode and connect it to your PC.
3--Get into send command mode as in step one.
-Put your device in download mode and connect it to your PC.
-Open port.bat and make sure to write down the number after com. There maybe different com numbers but choose the one that has DIAG1 on the same line as it. Note it down this is important.
-Hold shift and right click in any empty space in the extracted folder. Choose open command windows here.
- In that copy and paste this
Send_Command.exe \\.\COM[*insert your number here]
-Now you're in send command mode. Nothing looks different on your phone but it's find. It should just remain in download mode.
4-Now grab your command to flash system.img line of code from this post. It isn't the same as step one. Copy that an paste in the command window. Make sure it is for your device. They are model specific.
5--This should take a while so wait until you see the # again.
6--After thatLEAVEand upon reboot you should have root.
To Un-root just flash a KDZ file compatible with your device here.

Fantastic. This method will also ease devs for future rooted firmwares. I really cannot see LG being able to patch this, since this is basically a 3rd party LG Flashing tool. If they block this method, then their own tool will ultimately die with it.

This is a good method, thanks for writing this up.
I would like to add a few points....
I recommend you do keep your original system.img on your phones regular internal storage. If you encounter any boot issues you can then re-enter download mode and write the original system.img over the top of the failed root attempt. Use the same command from "step 3: root" but replace rootedsystem.img with system.img. This should still be on your phone from step 1 and will recover your phone from a failed root injection attempt. Note that it will not recover your phone if you messed up the dd command and overwrote other partitons. Be sure to use the right dd command and cut n paste to prevent seek/offset typeos.
I also recommend that you keep a backup of your system.img on your pc. When you run autoroot.sh in step 2 the copy on your pc will be renamed and patched. I suggest copying system.img somewhere else first, or re-copy it off your phone.
Additional credits to blog.lvu.kr. This is the blog of the hobbyist who reverse engineered the download mode protocol, created send_command.exe and gave it to the world. Kudos to you.
How is this any easier than the original method....if anything this requires even more work

Oh nice! I wasn't adventurous enough to try it. I'll make a system backup and give it a whirl!
Very nice thread, thank you. The steps were short, few, and fairly concise.
I was waiting for something like this where I could modify my own image and I wouldn't have to wipe everything or replace it with a new image.
One thing you might want to mention is that if your phone is encrypted, you'll need to unencrypt it first.
Can anyone link me to some instructions on how to disable OTA updates for an unlocked/international H815T?

This is what XDA is all about. It tells you how to inject root into your OWN system image. it's the opposite of spoon feeding. it's about teaching members how to do things for themselves. Too many people come here expecting to be spoon fed and have thigns done for them. This thread teaches people how to do their own work, while learning something at the same time.
Good work OP! :good:

Thanks. I guess people don't know what XDA is about. Seeing noobs and others trying to spit on hard work when I used my time and device as Guinea pig. Also people don't know this is almost brick-proof because the system image if from their devices. Unless they use wrong commands but all here is just copy and paste. They see lot's of text and get cold feet. Anyways will be updating the OP with system images. If yours is available please share. If you see your image available and you have drivers and LG_root downloaded proceed to step 3.
The only downside is that I have to drag out my windows laptop instead of doing everything on the ubuntu machine I use at work.
But if that's the biggest of my problems then I don't really have a problem
hi, thx for this tutorial, looks good
when flashing back the rooted img,does it wipe everything ? apps, data ... etc
thx
EDIT: just correct me if im wrong

How to calculator extractly bs/seek/count ?
Is there a possibility of any personal data being written to /system on a phone during normal use? I can provide 10c Optus AU (carrier 505-02) if I can be sure its not identifying, but ive been using the phone a couple of weeks.

I would also like to know this. You can resolve system by running the following. Note that this is for the H815T and is not the same on all variants.
# ls -lZ /dev/block/bootdevice/by-name/system
You'll get something like:
lrwxrwxrwx root root ubject_r:block_device:s0 system -> /dev/block/mmcblk0p47
Which tells you the actual block device (partition its on).
And you can see the size of that with:
# cat /proc/partitions
where you see:
major minor #blocks name
<snip>
259 15 4239360 mmcblk0p47
<snip>
However I dont know how to identify how large a block is or how to calculate the start offset in the main partition.
ok, it worked great
wasnt easy, since im not so familiar with using ubuntu, but all is ok
the explanation of the how to... was great and nothing lost
my H815L is now rooted
thx guys

I know it's kind of going off topic, but I figured I'd mention that Flash Fire doesn't work on VS986. It just goes to a black screen and sits there forever. I left it sit for almost an hour. I saw elsewhere it has something to do with automount, I'll have to mess with it further.

Appreciated but you should include a way to unroot (undo) as well, ie how do we get back to stock (if required) ?
