Anyone know how to Root ASUS Zenpad 10 (Z300C)?

Hello,
Does anyone know how to root the new ASUS Zenpad 10?
I tried the method for the Zenpad S, Kingo app, DingDong app and Towelroot app none have worked.
Any ideas on how to root this tablet are appreciated! Thanks in advance!
Specs
OS: 5.0 (Lollipop)
CPU: Intel Atom x3-C3200 Quad-Core, 64bit

What about iRoot? Looks like it might have worked for other Intel Atom x3 tablets.

Thanks!
But I sold the Zenpad, I never got a chance to try iRoot. If any one has a Zenpad 10 and would like to try iRoot to confirm if it works or not, that may be good for other people who read this thread.

I've tried iRoot but without success.

asus zenpad z300cl
Hi,
i want too , to root my new asus , and i have tested most solution but no work,
There no solution ?

I'm looking for any functional root solution too ! :fingers-crossed:

I emailed asus today and they told me it is rootable but wouldn't help me

Hello,
I think that with android 5.x ...there have no solution to root with one click.
...
I am waiting for my Zenpd 10 Z300CL too.
CPU: Intel Atom Z3560
O.S: Lollipop 5.0.1

not sure if it will work for the zenpad but take a look and see...
http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096

any luck ? I just got one yesterday

Actually, I am with ^, I am wondering if some people are having luck with this tablet. I was thinking about using root for some gaming reasons, but towel root isn't working and there isn't anything like nexus root toolkit, so I think that I am going to screw up the tablet if I do it the old fashioned way because I don't have much knowledge in that area and don't want to mess up my brand new tablet without good reason.

I can't get fastboot working... I can boot into fastboot mode but my PC does not detect it (adb works fine). Tried on Ubuntu 15.10 64 bit and Windows 10 (10240) 64 bit.
If anyone can get it working, then this should work: http://forum.xda-developers.com/android/development/zenpad-s-root-achieved-t3160422

Not even with the other methods (T1, T3 and T4) or recoveries?

I tried all the four T options, but nothing..recovery choice doesn't matter, if bootloader doesn't accept the flash commands..
Note that I tried also the standard command "fastboot own unlock", just to see if bootloader is unlockable..Fastboot seems to accept the command, but after reboot bootloader still locked.
I tried rooting the device using adb too..the problem is located into the default.prop file, where some parameters don't allow adb to retain or gain root permissions. Those parameters are:
ro.secure=1, which forces adbd daemon to drop its permissions to the standard (shell) user, even if it always starts as super user at the beginning (while if to.secure is set to 0, it allows the adbd daemon to retain root permissions after starting);
ro.debuggable=0, which doesn't allow adb to gain root in production builds using the command "adb root" (if ro.debuggable is set to 1, it allows adb to gain root permission and the subsequent procedure for pushing the su binaries.
No luck at all..neither using the "one click root" tools, like kingo and similars, of course. I'm trying to find some tricks for rooting this baby, I'll update you guys with news, if I find something
Oh, btw, I missed to underline that I'm trying to find a method which doesn't force me to unpack the entire firmware, extract and unpack ramdisk, extract and rewrite the default.prop file, and then repack the whole stuff just to make adb working with root permissions..it is possible, but I consider it as the LAST chance (I'll do it though, if I won't find other ways)

I still have not found any way to root

Recently bought Zenpad 10 z300c from China and it has all the chinese apps that i don't want. Nowadays everything is using Google Services and for some reason i can't get it to work, they always crash. So im also looking for way to root it. There is no way to change the firmware without root from CN to WW right? My tablet also goes to fasboot but windows 7 can't find it.

You need a special fastboot for Intel devices.

It is a fastboot specifically for Intel devices, however it does not matter because no one has rooted our device.

[GUIDE] Full ADB Root, System RW, and DM-VERITY Off for Sprint LG G5! [ZV4]

UPDATE Thanks to @thjubeck for testing this, it seems that this userdebug kernel actually works on all devices running antirollback v0 and running Marshmallow! I only have the Sprint variant, so be careful!!! Enjoy root guys
A bit of a disclaimer is that this is root through adb. dm-verity is off and system is rw, so you can install apps as root, get a hotspot hack to work, and anything through a shell but I am having trouble installing SuperSU. Please try yourself though as I am probably doing something wrong! If there are any bugs you have found please post them, as this phone is my backup and not my daily driver.
So okay, here is the guide:
PLEASE MAKE SURE YOU HAVE A WAY TO GO BACK INCASE THINGS GO WRONG. DO NOT ATTEMPT TO ROOT THIS WITHOUT HAVING A KDZ/TOT FOR YOUR DEVICE THAT YOU KNOW YOU CAN FLASH BACK TO. I AM NOT RESPONSIBLE FOR THINGS GOING WRONG.
1. Download this zip
2. Install Terminal Emulator from the Play Store
(This is modified from the V20 bootloader unlock, HUGE thanks to all of those devs for sharing their dirtysanta code with me and allowing me to modify it!)
3. Copy all the files from inside the "dirtysanta-boot" and paste it into your active ADB directory
4. Plug your device into the computer and verify ADB is working. Then;
On Windows, double-click "RUNMEFIRST.bat, DO NOT CLOSE THE LOG WINDOW THAT OPENS, then double-click "Step1.bat"
On Linux/MacOS ("#" Signifies a comment below)
Code:
./RUNMEFIRST.sh
# OR
bash ./RUNMEFIRST.sh
Open a Separate Terminal next to the RUNMEFIRST terminal, then type:
Code:
./Step1.sh
# OR
bash ./Step1.sh
(When you run The sh or Bat files there may be a Permission denied error on 2 files: Flatland and Flatland64. This is normal and nothing to worry about.)
5. Wait for a shell prompt, then type (or copy):
Code:
run-as con
chmod 0777 /storage/emulated/0/*
6. Open Up Terminal Emulator on your phone
Type:
Code:
id
Check if context is "Untrusted_app". If it is then we're good to go!
7. Type into Terminal Emulator:
Code:
applypatch /system/bin/atd /storage/emulated/0/dirtysanta
8. Watch the RUNMEFIRST dialog for when it tells you to run Step2 (we don't have a step 2)
9. Reboot the phone into recovery mode and wipe data again
BOOM! Now the you have a userdebug kernel running on a userdebug system Time to turn off dm-verity, otherwise you will have a red triangle on reboot (Your device is corrupt. It cannot be trusted and may not boot) and cannot edit /system.
1. Finish setting up the phone and enable USB Debugging in developer options (you should know how to do this)
2. Plug the phone into your computer, and run these commands
Code:
adb root
adb disable-verity
3. Reboot the phone
4. Run
Code:
adb root
adb shell
mount -o rw,remount,rw /system
Bam. Enjoy your FULL UNLIMITED root shell with system set to rw and dm-verity off!!! Just make sure to type "adb root" before "adb shell"
If you ever want to go back, just flash your stock TOT/KDZ with UPPERCUT and you'll be all good!

Nougat is the latest update (ZV8 I think), this only works on ZV4.
Glad I stayed on ZV3 since July.
Happy this is out now. There was some sass going on in another thread but it seems there's still some civility among us. I'll check this out and report anything of note. I'm most interested in a viable hotspot mod, so if I can figure out how to modify the APN settings I'll be quite happy. Will donate as soon as I figure out how.

Lucky you! Make sure you flash the stock ZV4 TOT before trying this
An unlimited Hotspot is definitely possible. I'm on mobile right now but I'll see what I can do when I get home.

I'd be first in line to give this a whirl in the real world but I'm leaving in the morning for a week or so on the road. Maybe I'll be able to do some playing around at the hotel. Hotspot is the brass ring, adblock is a close second. I've survived this long, so hopefully a few days of testing and squashing bugs won't kill me. I do want to be of service to the community if possible. It will be interesting to see how these new developments affect the development of the various G5 variants.
My apologies if I insinuated that I'm at all peeved with anybody working on this device or just offering encouragement. I know there are some conflicting personalities in the mix right now, so I hope everybody benefits and sees the value in what you're potentially onto with this.

Thank you!
Unfortunately ZV5 has antirollback enabled, so you can't downgrade to ZV4. If you really want to try it you can attempt to flash the ZV4 userdebug boot without the userdebug system (just follow the guide past the TOT steps) but I believe it will bootloop. I have not personally tried this so I have no way of saying for sure, but it'll probably bootloop.

Honestly your name does you justice! Thanks for your hard work

So bummed that I updated...

so should i just update to nougat now?

EDIT: No items in the Google Drive folder? Am I missing something?
I'm definitely hoping to spend some time testing this out, but it's bad timing that I just got the family out on vacation. Hopefully I'll spend some time tonight or tomorrow, and quite likely after the 25th I'll have some time.
Meanwhile, I've got to figure out a solution to getting ADB working on my MacBook. It's EFI locked so I can't install the full SDK, and my windows VM isn't working either. Since I'm pretty sure I need a windows environment that will be my first hurdle. I wish I could sit down right now and just try it out for the community's benefit, but hopefully we'll get there soon.

Man I feel like buying a G5 just to try this on nougat! Does this also unlock the boot loader or allow twrp to be flashed?

It only works if you still have version ZV4 or lower, so forget about nougat. At best you'll be rooted on ZV4 forever with a wonky system.
It will not unlock the bootloader since it's just a user-debug upgrade for tinkerers, but nonetheless useful to some.

Wait. Where did you get the userdebug build for G5?

Plug your device into the computer and verify ADB is working

Could this be a means for (or a step closer to) getting full root, or is that basically off the table?

OEM Unlock?

Hi all,
I don't have this phone yet, but was wondering if the bootloader can be unlocked. If it can then it will be possible to root.
Here is a simple guide, if there is anyone here that would like to try. No software required.
http://techbeasts.com/how-to-enable-oem-unlock-on-android-nougat/
If OEM Unlock shows up in the developers options menu.. good news!! If OEM Unlock doesn't show up, then there is no way to unlock the bootloader.
Please let me know if your phone is the Amazon Prime version. The Prime version may be locked down.
Thanks for any replies!

Prime version is indeed locked down. Also, at any point that you change anything on the phone to do anything with the software, Amazon will not provide you updates again.

I was able to unlock developer options in my Amazon version but now what? I'm assuming that the bootloader is now unlocked and theoretically, I should be able to flash a new rom? Problem is, does one exist? Cheers.

Just an FYI that my Prime Version did allow me to activate Developer Options/OEM Unlocking. Next step is trying to find a rom or even flash it to regular factory default. That I have not found yet.

Quick question SDACymru - I'm getting this phone in a few days... how did you perform the OEM unlock in dev options?

The normal way. Just tapping on the option for 5 or 6 times.

Thanks. Is there a reason we shouldn't be able to restore from a backup of a non-ads phone stock image and at least get that running on ad-based versions? From my understanding they are exactly the same hardware-wise, so should be possible...

Being able to expose "Developer option" and access to "OEM unlock" still don't make this is developer-friendly device, but I quite surprised that the Amazon Prime version even show the "OEM unlock" in the "Developer option". Anyway, it is close, if you can also perform the last 2 steps, then this device can be considered as developer-friendly.
The next 2 steps are:
- Reboot into fastboot
- fastboot oem unlock (from adb console)
Some devices with full fastboot implementation can check the device lock state by
- fastboot getvar all
If all these commands work, then the device will have good developer support. In addition, if all these commands work on the Amazon Prime version, then it is a piece of cake to remove the Amazon ads.

did anyone every try any of this? ADB Shell temp root has been achieved on this model, I have the temp root xploit but it's useless unless people know what they are doing with it. You can easily brick your phone. I don't physically have this phone but what I do have is a little knowledge, access to the stock rom and a way to flash it. I also know that the recovery can be swapped with TWRP during that flash process. Hit me up on Telegram: https://t.me/PizzaG

So being that I have actually gained temp root access (all credit to PizzaG, he knows his stuff)
Should I go ahead and give the fastboot steps a go? Would the persdata\nvdata remove the temp root access with a reboot or am I way off course?
Any input appreciated

Just rebooting you will lose temp root access. all you have to do is run the commands again any time you want adb shell temp root.
Please check out my new thread in the idol 5 forum. I have some things and ideas brewing

Sony Xperia XA2 - Unlocking

I'd like to start a discussion on unlocking the XA2 bootloader and rooting it. So far, it looks like for Sony devices, you need to send a request through the Sony site here: https://developer.sonymobile.com/unlockbootloader/
But there is no device selection for the XA2. This is where i'm currently stuck at. Does anyone know of any other way to unlock the bootloader?

Okay got it to unlock bootloader.
Steps:
1. Head to https://developer.sonymobile.com/unlockbootloader/. Select Xperia XA1 in the dropdown, follow steps, then get your access code.
2. Pretty much follow the steps in that guide from sony, where you get the access code. The only difference was when installing the fastboot drivers. On win 10, i had to go and follow the steps here to install android drivers: https://android.stackexchange.com/questions/129174/windows-10-fastboot-driver
After that, fastboot was able to recognize the device and unlock the bootloader.
So now, i guess i'm waiting for TWRP to be released for XA2 to get recovery and root.

I've been looking for a XA2 page for a while. Can we request one?
This is a interesting device and I hope the development community shows some interest too.
What's your impressions of it so far?

Agreed, I'm quite shocked there is no development threads as of yet for this newly released device. Already checked mine, and can see that sky mobile have left it unlockable, so I would also be interested in development for this device.

Same. I bought it off Amazon US and I didn't realize I was buying such a recent phone. To any future devs, add "Night Light" feature and swipe fingerprint to bring down notification bar to any ROMS would make this phone a great sucessor to my Honor 8.

XA2 has been perfect for me so far, coming from Nexus 5x. I mostly use my phone for reddit and podcasts, though. Just need my LineageOS on it.

i unlocked mine also

Hello, what about fingerprint scanner usability after unlocking? I've heard that after rooting your phone scanner may stop to work with banking and other similar apps. Maybe you noticed other changes after rooting?

I haven't been able to root yet. I've only unlocked the bootloader, which hasn't caused any problems with bank of America. on my other phone rooting didn't affect bank of America, however Android pay didn't work, and snapchat can only be logged in before root and not after. once you root, you won't be able to log back in snapchat if you logout, however if you log in it'll stay logged in after root.
I've been having problems with the windows 10 fastboot and ADB drivers. i got fastboot to work long enough to unlock the bootloader but then it stopped recognizing my phone. still haven't gotten ADB to work yet ?*

The wait game begins. I'm going to wait to unlock the bootloader until TWRP and root available.
Btw can't you root without changing the recovery using ADB. I don't kno since this my first ever Sony phone.

I think you can sideload with ADB once the bootloader is unlocked. I was under the impression TWRP is like a GUI for ADB. but There's something funky with the windows 10 drivers. it took forever for my phone to get detected in fastboot, and ADB never seemed to work. then, after i unlocked my phone, the PC doesn't even recognize it in fastboot anymore.
likewise, I've always used Samsung phones & odin. This is my first Sony. the lack of root is killing me ?

From what i read, adb sideload requires custom recovery.
Is anyone else on Project FI with this phone? I'm getting awful 4G and wifi performance with the XA2. Constantly losing internet access (even though signal bar is at 5 bars).

Hi guys, I managed to unlock the bootloader but I can not get into recovery mode. I tried with vol- and power button but it does not work . Did it happen to someone? Thank you all

for this, you will need a custom recovery GUI such as TWRP. I believe tht all you can do on this device by pressing volume- is access ADB, and volume+ gets you into fastboot, which can be accessed via command prompt on a PC

Isn't TWRP basically just the GUI of all the ADB commands? I was under the impression you could do almost everything you can do in TWRP in ADB CLI mode on a PC ?*
I was under the impression to sideload you can boot with a USB plugged into your computer and your phone press volume- Then the indicator light in the top right corner turns green, and (if the drivers on my PC would cooperate) then it would accept ADB sideload commands. Now, I am unsure of this; that's just what my basic understanding is. If I could get the damn drivers to work right, I could find out for sure ?

I don't know nearly enough about the android ecosystem to comment, beyond what i found. I think adb sideload is a specific command, which requires twrp. But other adb may work? I don't want to risk it yet anyways.
Regarding drivers, did you try the thing i linked in my first post on this thread? My XA2 is still recognized after bootloader unlock with my method.

What do you know flashtool supports our xa2? that I know no because I tried to convert an ftf file but in the device list the xa2 is not there. also does not recognize me in flashmode despite emma recognize it. thank you

How can I root an Android TV? Mine is JVC LT-40CA790. Android version 9.0.

I have turned on USB debugging in dev. options.
I believe it is possible to root android TV with Magisk and with or without a custom recovery, depending on the method. Please see the tutorials linked below for reference:
On my PC connected to the android TV using ADB appcontrol, I can type: adb reboot recovery or adb reboot bootloader (although I am not sure which one to use, as I am unsure on what is the best method to root my android TV simply and easily. I do not want to lose my data and I believe that is what happens when you unlock bootloader, but not if you do via custom recovery method). No.1 is the tutorial I am trying to follow, as well as secondary tutorials if the first one does not work (and if I am struggling with doing custom recovery);
2b (to be done before commencing onto no.2):
(if I am really struggling and all else fails, but I honestly think this tutorial isn't that great, as there some things like finding the firmware for the android TV I am REALLY struggling to find!! I know it's version though - it is 9.0):
