[Q] EVGA Tegra Note 7 root?

[dark42]

EDIT:
Go here to root your Tegra Note 7: https://github.com/linux-shield/shield-root/blob/master/README.md (thanks to CampGareth for finding the link).
I have tested this, it works with no bloatware, only installs SuperSu.

---------
Hey guys, I got my new Tegra Note 7 last night and I've been trying to get it rooted, but I keep running into trouble.
First of all, I DO NOT want to use some shady Chinese software that installs a bunch of bloat on both my tablet and PC just to get SuperSu going, I've tried that method and had to reset the tablet to get rid of all the crap it installs (and it didn't even seem to root anyway).

Now I'm trying the manual method from here: http://pan.baidu.com/wap/link?uk=3073396937&shareid=3129426036&third=0
Which, again, is Chinese but at least I can see what it's doing since I'm issuing ADB commands, and supposedly it has worked for others on this forum.

Now, I get to step 3 on the included PDF which says to boot an insecure bootloader image with "fastboot boot tegranote_insecure_boot.img", I do this and the tablet screen flashes a few times and reboots to android.
I get to the next step which says to open an adb shell, and do "/sbin/rootsh +p" to get a temp root shell, and this is where I get stuck. Instead of getting a root shell I get the message "/system/bin/sh: /sbin/rootsh: not found". Does anyone have suggestions?

By the way we really need a Tegra Note 7 subforum here at XDA, if the mods could add it that would be great.

I would recommend the following procedure:

1. Download the root_tool_v2.zip attached to this post
2. Unzip the contents the root_tool_v2.zip to a directory
3. Run the following commands from your ADB and Fastboot directory:

adb reboot bootloader
fastboot boot tegranote_insecure_v2.img

4. Once your device finishes booting the insecure boot.img (Your device's screen will blink several times and then boot into Android) run the following commands:

adb shell
mount -o remount,rw /dev/block/mmcblk0p5 /system
exit
adb push su /system/xbin/su
adb push Superuser.apk /system/app/Superuser.apk
adb shell
chmod 6755 /system/xbin/su
chmod 644 /system/app/Superuser.apk
mount -o remount,ro /dev/block/mmcblk0p5 /system
exit
adb reboot

5. You should now have Superuser installed and have root access.

What I did was I modified the boot.img provided to be insecure and use an insecure adbd binary to allow a root shell when booted from which can then be used to setup Superuser and su binary access. Let me know how this goes for you and if you have any questions .

Wow, thanks for the help! Unfortunately your attachment seems to be corrupt, I can't decompress the archive. I'm using 7-zip btw. The forum says your attachment is 7.19MB but when downloaded it's only 160KB.
If you can re-upload it I will give it a go.

a reup of the file would be much appreciated! :good:

PS
i have a batch file to expedite the process.

Re-uploaded the file for you guys let me know how it goes for you .

Awesome your new package downloaded fine.
However I'm still not getting root, I got to step 4 and when I open an adb shell I don't have permissions to do the next command.

The exact error message:
[email protected]:/ mount -o remount,rw /dev/block/mmcblk0p5 /system
mount -o remount,rw /dev/block/mmcblk0p5 /system
mount: Operation not permitted

So I guess the insecure boot image didn't work right. I should mention that I am using the latest Tegra Note firmware, I don't know if that makes a difference though. Any ideas?
Thanks for your help so far.

do you guys have a copy of the drivers for the tablet? mine only seems to work for storage.

update: got drivers working.

I used Universal Naked Driver 0.73, I just manually installed the driver for the Nvidia Shield, thinking it would work, and it does!
Does shimp208's root image work for you, dergezero?

no, it just reboots. neither is working. im going to see if any one can give us a dump of their img that already works to be rooted. i tried that Chinese method and its really annoying and i dont get root on any computer i try it on.

Hey guys I am in the process of creating a new boot image that uses a different method for gaining root access and will upload that once I finish it.

:good: Awesome man, good luck! Eager to try it when you post it! :fingers-crossed:

I agree, with the amount of malware that is in the chinese root tools, it makes me nervous to use the one the OP posted.

I wonder if someone would be able to port Clockworkmod Recovery to the TN7 eventually. The bootloader on this device is factory unlocked so it should be simple enough. Unfortunately I'm not a good enough programmer to get this done.

If we had Clockworkmod then rooting would be as easy as flashing the SuperSU .zip from the SD.

I have updated my original post with the rooting instructions to include a new insecure boot method follow the same instructions as before just use the new boot.img I uploaded to that post. Credit to teknoraver for the insecure adbd binary.

I tried your V2 image, still getting permission errors when doing "mount -o remount,rw /dev/block/mmcblk0p5 /system", what am I doing wrong?

When you boot the image and then type ADB shell do you get a root shell ([email protected]:/ #) or just a regular shell ([email protected]:/ $)?

Amazing

Nice to see you working on a different method of root... I am sorry to those who feel that the method I posted is getting negative reviews just wanted to throw something out there for people... however, I do feel much better with Shrimp208 working on a better root method I really wish we could get a forum going..

I used the Chinese root tool and all seems fine on my Tegra note

Just a regular shell with $. Doesn't look like I get temp root permissions after running the tegranote_insecure_v2.img.
If it matters, I'm on the latest Stock ROM (4.2.2/JDQ39.13155_268.1942) and I'm using Universal Naked Driver 0.73 for the Shield, which works with this device. Maybe I need to use a different driver?

yeah it works but you dont really know what was installed on ur phone or on your pc. 3 apps are installed on your phone and a few reg changes on ur pc can be detrimental. and its all bloatware
