hi guys i turned on s because iam sending this back to tmo. but i forgot to flash the stock recovery img and now i am attempting to root again with visionary. it says already rooted. but it wont give me permission. and the s is on. what do i do please help...

anyone...?

This is probably going to get moved to the Q & A forum before I can finish posting this.
I have yet to find an easier root process or an easier set of instructions to follow, than the following post...
http://forum.xda-developers.com/showthread.php?t=834225
Please read that in its entirety. This is such an easy process that anyone who gets lost or messes it up, might not want to try it in the first place. I'm being as honest as possible, not trying to be insulting.
Ultimately, S=On is part of the un-root process, soooo, you're back at scratch. This means you would need to start back at the top of that post above and follow the instructions on how to root your phone/get S=Off.
Good luck!

i understand BUT when i run visionary it tells me already rooted.... but when i type in su it says permission denied....

We're going to need some additional details. You on 2.2.1? Have you restarted your phone since and tried again?
I'll spell it out for you - it really is dead-simple...
(***paraphrasing the OFFICIAL instructions in the thread I linked to above***)
- Enable USB Debugging
- Extract the root.rar in the original post - MAKE SURE YOU PAID ATTENTION AND NOTICED THERE IS A ROOT FOLDER WITHIN A ROOT FOLDER - a nested folder. You do NOT WANT THIS. You want just one /root folder on your sdcard, within it at the .sh scripts.
- Install VISIONary
- Attempt Temp Root
- Run Terminal emulator, type su and follow the instructions in the original post to execute the script - reboot.
- When your phone comes back up, run VISIONary again
- Attempt Temp Root
- Attempt Perm Root
There is really no way to mess this up. I have done this on 6 MT4G's, so if it's not working, you didn't follow the instructions - no doubt, no question. You don't need ADB - you can do this all from your phone with a file explorer (I use EStrongs) and a terminal emulator (I use Android Terminal Emulator).
I'm surprised this hasn't been moderated yet...

What do you mean it "tells you already rooted"? I am rooted and just running VISIONary - that is, launching VISIONary - it doesn't tell you anything. If you click Temproot now, is that when it shows that?
You know you have to first do Temproot and then do Permroot, right? From what I've seen, you can't "over root," so honestly, I highly recommend starting over again. If possible, I would literally type out each and every step you're taking. Maybe it will show us where you're messing up.

Try a different version of visionary... r11 is my preference

Good call. I thought about that as soon as I finished my last reply - i.e. check the VISIONary version.
I've been using r14 since my first MT4G and haven't had a single issue on any of the MT4G's I've used it on.

guys loook.... i am using r11 when i click root now.... it says already rooted i can access the clock work recover and everything but s is on and i dont have super user permission.... i turned the s on but now i cant turn it of. i dont have super user permission in terminal

So that means you used the unroot.rar file and the process outlined in the first post? That's how you got S back =On again?

ok finally i got it. but now it wont let me flash the stock reocovery image i tried in adb and terminal in terminal it says file not found. and in adb sending reovery<3948kb> falled< status malformed help..... i have to send this back tomorrow

Please post questions in Q&A section.

Root help, i'm confused!

Hi there everyone,
I want to root my Desire HD, but I don't want to install any custom roms, radios, etc. I only want to root my HD so I can install apps that require root. I see no advantage in installing any custom ROMs, so I want to leave that alone.
What's the best way to go about this? I've found this guide: http://forum.xda-developers.com/showthread.php?t=834427. Do I need to do anything else, except what is in this guide? I'm terrified of bricking my phone!
Could I brick my device if I made a mistake with the above guide, or S-OFF?
Thanks in advance,
Alex
Sorry for the question (no doubt it's been asked before), I've rooted my old HTC Hero before, found that easy, but this I'm confused!

Hi there. I'm actually quite a noob at all this since rooting is all new to me but seems you and I went after similar threads because I also read that guide to rooting the DHD at first. But after some further reading I discovered this is actually a much more difficult method of rooting (maybe because it's older?).
It will really, really help to look in this thread: http://forum.xda-developers.com/showthread.php?t=846248 as it explains so much and has many useful links.
But in answer to your question read this guide - http://forum.xda-developers.com/showthread.php?t=841076 A much easier method of rooting =)
Good luck.

After I've ran that step - do I have permroot and I don't need to do anything else? I only want root, not custom ROM's.
I'm scared of doing the permroot, sounds like I'll break my phone if I even attempt it! Is there any way to ensure it will work?

Yeh you will be perma rooted if you follow the steps. About ensuring it will work, this is something I am now looking into myself. I'm getting the impression that it's possible to create a copy of the stock rom even without the perma root and using that to do a recovery in the event of a root failure. Though I would have thought perma root would have been needed to do a recovery in the first place....
I've got a thread below yours where I'm still trying to get a clear answer as to how to do all that. If I find out I'll let u know =P

By "if you follow the steps" - do you mean I only have to follow step 1 for perm root? Or more than that?
Sorry for all the questions, I really do appreciate your help, thanks!
And also - if it fails, the stock WWE RUU can be flashed to restore the phone, can't it?
EDIT: Followed step one, restarted device and everything - perm root stays. Thanks for all your help mate!

Go all way through these steps from 1.1 to 1.6. Once you've done 1.6 your phone should be rooted. Just download the terminal emulator from the market and do that last thing that is mentioned to test the perma rooting. If that works then your good.
Oh just so you know the temp root option in Visionary is apparently completely safe and won't harm nothing because it makes no changes to the system partition.
Not sure about the WWE RUU. I'm not sure it will be compatible with your current ROM (Only thing I do know is that if it's older then your current it won't work). Don't know how to flash it either tbh, that's something I ain't found out yet =P

do I need s=off for cyanogenmod 7?

I have ROM manager premium, and I just downloaded CM7 through it, and was about to flash it, but remembered I dont have s=off.
Also, I cannot get past this screen no matter what. htt p://img145.imageshack.us/i/20110222142411.jpg/

Thanks for answering, but I am rooted, I used the visionary perm-root method. I have terminal emulator and typed "su" and it prompted for super user access. I also have a few apps that use root, which work.

Root access alone is not enough. You need S-Off as well.

for short terms "s" Means security protocol. If your S=ON that means the phone will do a search each time you boot the phone on to see if anything as been tampered with. and if it has it will revert back to a factory status. Just like you first bought the phone. Which includes rooting, recovery images, boot images, engineering screens. What ever you do to your phone that isn't factory will be undone.
It is impossible to do. Because you need to flash the ROM from the recovery image. And since one you boot your phone it will replace Clockwork ROM manager with the factory style recovery image, you cannot not even get to the place you need to flash it from.

Correct because you flashing the Clockwork Recovery image will not STICK unless you have s=off.
They system will replace the aftermarket image with the original EVERYTIME you turn off the phone.

That is the Stock Recovery. You need S-Off and ClockworkMod Recovery. And the right release of CWM Recovery, also. Use CWM Recovery 2.x to back up, restore, and install Android 2.2 (Froyo) based ROMs, including stock, and CWM Recovery 3.x to back up, restore, and install Android 2.3 (Gingerbread) based ROMs, such as CM7.
There is a special version of CWM Recovery that can manage both Froyo and Gingerbread ROMs: 3.0.0.6. Search for it in the Development subforum.

Thanks for all the information, I am slowly learning, and trying to understand all of this.
I am currently trying to get s=off. I found this link via google : ht tp://forum.xda-developers.com/showthread.php?t=858996
I am already "rooted" I believe, because I have superuser access. Should I unroot first?
Also, in order to back up my current(stock) rom, do I need to use clockwork recovery 2.x?

you can use the link i posted ^^^ there.
I will state this though. That link that you posted is the simplest way of truly rooting your phone. If that seem complex i would advice against you doing it at this point in time.
Rooting your phone basically turns your phone into a computer that can make and receive phone calls. And doing the wrong thing at the wrong time will seriously FUBAR your phone.
If you take a look in the Q&A section and the General Section you will see TONS of post with people in your shoes that didn't know what they were getting into and didn't take the warning laid out there.
READ READ READ about the android ADB before you decide to root your phone. And learn what everything is and what it does.
not trying to sound like a "Richard" but i don't want to see you mess up your phone either.

Isnt that just a video of temprooting and then confirming the root with terminal emulator?
I have seen many people with problems and they think they bricked their phone. I dont want to be one of them, and I've had a few close calls, and I'll tell you it wasnt fun.
From what I see ADB is just a remote terminal?
I appreciate that, and have taken the warnings very seriously.

[XOOM2/XYBOARD][HOW TO] Motorola Xoom 2/Xyboard Everything Root and more!

XOOM2/Xyboard Everything root and more!
From 26/03/2014, I will no longer be updating this post as I no longer have the device and Motorola won't be upgrading the device further. Please instead of sending me PMs, go to the Q&A board or post your comment on this thread.
Note: This method will not work on Windows 8. Only Windows XP, Vista, 7, Linux and Mac OS X is supported.
Root Method - Honeycomb
1. Download the Windows version here, or the Linux/OSX version here.
2. Your Computer must have Motorola Drivers installed before rooting and connect your device with debugging on to your computer via USB. (Mac Users don't need drivers)
3. Extract the zip file from the download link, and run “run.bat” (on Windows) or “run.sh” from a terminal (on Linux/OSX)
4. Your device should reboot a few times during the process, don't worry.
5. Then you should see a finished message on the Root Method Window. At this point your device is safe to be removed from the computer.
7. As you are running Honeycomb if you are reading this then you should be receiving the ICS OTA soon. So lets backup your root so you can restore everything root after the upgrade (saves time). Download OTA Rootkeeper and backup root.
6. Well Done! You have root. Enjoy root and be safe.
Blog Post: Here
Root Method - Ice Cream Sandwich
1. Connect your Xoom2/Xyboard via USB to your Windows PC. Install Motorola Drivers from here.
2. Under Settings > Developer Options > Hit the "Enable USB Debugging" selection.
3. Download the Root Installer from here. (Says for Droid RAZR but also works on Xyboard and Xoom 2]
4. Unzip the download.
Bootstrap/Safestrap[Custom Recovery]
Waring: DO NOT proceed if you are inexperienced. bootstrap is messy and is only needed once we have ROMs cooking. All questions about the recovery ask in the developer thread.
1. Install the Bootstrap APK file.
2. Allow Superuser Powers.
3. Read the instructions which is displayed on the user interface.
5. You will now see a splashscreen after you reboot (before boot animation), here you can decide if you want to enter recovery or continue with boot.
-Method Under Constuction-
Unroot or temporary unroot
Temp Unroot - If you need to unroot for any reason and come back at any time, then install OTA Rootkeeper and then select the option "temp unroot). This will remove root without restarting and you can restore by a touch of a button.
Full remove of Root - If you want to complety remove root all together, if you need to send in your device for repair or trading your device. Install Ginger Unroot and continue with the onscreen instructions. This application has confirmed to work on the Xoom2/Xyboard.​

the thing is that maybe you can, but you might not want to Unlocking wipes all your data, apps, etc and also permanently sets a variable stating that your warranty is gone.
It might, for example, be desireable to create a backup of all your apps and data using titanium backup, which requires root, before unlocking your xoom.

Does this mean that more knowledgeable folks can create custom ROMs now, or does that still require an unlocked bootloader?

No, we need to figure out a bootstrap for custom roms. No custom kernels.
Also, the method to fix adb remount is reset every other boot by the kernel, init.rc rebuilds local.prop on reboot as a failsafe and can't be changed without a custom kernel...

Just to let you know this does not work on all Xoom models like you say. Here is my thread with my specs in it. I have tried it three times following the directions to a T and it never gets past;
"[*] Initiating Phase 1...
[*] This may take a few minutes, don't mind the buzzing."
I have now let it run for over an hour each time and it never goes any further and my Xoom is still not rooted. It did not even ever reboot on its own. Does anyone have any suggestions? If not I'll just use some threads 1 & 2, I got from a friend.
Thanks, InfiniteImmortal

Not this method. It is supposed to unlock and root motorola devices in 10 minutes without deleting any files. When I read about this on android police I was very excited as I never rooted because I only needed Superuser for my Xoom (never was interested in ROMs) and could never justify scraping everything just for this.
I tested the files here on a windows 7 machine... if I run from command at step 2. I get su permission denied. If I run the batch file I get "failed backup" loop after the device has been detected
tried the portable one click .exe found in "Motofail: Universal Motorola Android Root Tool (Portable)" works perfect on my bionic
obviously fails to remount as it does not include local.prop from step 5. so it's not working on xoom
This is the most awesome root utility I ever came along. It took something like 6 mins to root my phone without losing any files, if I can get it to run on my Xoom this will be just a dream come true!

Update: This root method does not support the Original Xoom. Confirmed by Dan.

Installing OTA on rooted Yoga Book

Hello,
I am new to rooting. Several months back I rooted my yoga book using magisk. Root was great except that I couldn't install the Nougat update. And because I didn't think I needed it, I did not make a backup of the stock ROM.
I have tried to unroot the device using the magisk uninstaller. The OTA update still failed to install.
What path should I take to unroot my tablet so it can accept updates?
Thank you very much for any help.

I can confirm that re-flashing an older stock version is possible and restores the ability to install OTAs if you don't have a backup at hand.

Great! I had looked at that post but was unsure what action to take. I downloaded the YB1-X90F_USR_S000196_1611040312_WW06_BP_ROW-flashfiles.zip from the link you posted. Should I follow MarkAllen's instructions in the previous reply to unzip the folder and used fastboot commands to flash the ROM?

For me it was not worth the trip.
I rooted to be able to uninstall NoteSaver because it had an incredibly frustrating glitch when switching to handwriting mode. Several OTA updates did not fix the issue, so I felt great fixing it myself. I didn't use root for anything else. Overall, the time spent troubleshooting and researching was too much. I use the Yoga Book at university to take notes and it was very hard to find time to try to unroot the tablet and get Nougat. I never bricked the device but I spend many hours resetting it.
If I used root to do something more interesting and had more time to play around, sure it might be worth it.

You probably might want to lock the bootloader at the end before you execute the continue command.
Code:
fastboot flashing lock
And it might happen that you face an error while flashing that oemvars bootloader_policy-oemvars.txt. I couldn't find out why that happened and ignoring it seems to be harmless.
As soon as the system started you need to skip the whole first setup and to restore the country code as explained by MarkAllen. Otherwise you might need to re-start from the beginning after installing an OTA.
General info for people that didn't root their yoga book and just want to re-flash the stock system: You'll need the info from this thread since chances are high that you face problems with the usb drivers.

since there is no better rom around, I guess rooting is waste of time - for this device

You probably might want to lock the bootloader at the end before you execute the continue command.
Code:
fastboot flashing lock
And it might happen that you face an error while flashing that oemvars bootloader_policy-oemvars.txt. I couldn't find out why that happened and ignoring it seems to be harmless.
As soon as the system started you need to skip the whole first setup and to restore the country code as explained by MarkAllen. Otherwise you might need to re-start from the beginning after installing an OTA.
General info for people that didn't root their yoga book and just want to re-flash the stock system: You'll need the info from this thread since chances are high that you face problems with the usb drivers.

Thank you very much! Could you just give me better instructions on how to restore the country code? These are the instructions MarkAllen linked to:
you need to input country code to enable keyboard. There are several steps as below :
a) Open ‘’contacts’’ app, create a new local contact ” test”
b) Click search button at contact
c) Input ####6020# code into search bar
d) Browser the country code list, then chose country code you want to use, such as US
e) Then DUT will reboot
How to I skip the whole first setup to get to the contacts app?

Those are exactly the steps you need to follow. It might take some seconds till the new window with the list of all available country codes shows up.
Just use the skip button on the bottom-right of the screen during the setup.

Thank you! The first OTA update installed without a hitch and hopefully it's smooth sailing from here.
I appreciate the excellent technical support!
