Hi everyone. I have a tablet from a famous argentinian whose devices quality is not the best (Noblex). This tablet has an Intel redhookbay SoC (x86). I tried to root it with Framaroot with no success. I also tried with apps like Kingo Root and Kingroot (disgusting, but I had to try them to see if they worked). Nothing worked. So I looked for a custom recovery and I found this thread which helps redhookbay users having a temp recovery like "above" the fastboot menu. In my case, CWM didn't work because power button selected the recovery item, but also fastboot menu item, so it always rebooted. TWRP didn't work either because touchscreen doesn't seem to work when I choose it. So and idea came to my mind: I could make an OpenRecoveryScript to make a backup and flash SuperSU.
I used adb shell to see if I could write a file in cache partition without being root. Of course, it didn't work, but then I typed "su" because it came to my mind, and boom! I was root, and even without any prompt that asked me if I wanted to grant root access for adb. So I thought "great! I'll remount partitions as rw and update the binaries to SuperSU ones". But, I had a little problem called Operation not permitted. Yup, I couldn't remount because I'm not allowed.
So, what can I do in order to root this thing? I read something about adbd Insecure, but I don't have any app that manages root to use this.
I don't know what to do, please help me.
Thanks in advance.

I have an eris running Zen-EXP Rev 7. Up until a couple of weeks ago, everything was peachy keen, and SU was working fine. A few weeks ago I decided to try flashing a newer version of SU (the one found here on the xda forums), and made a Nand backup before doing so. After flashing the updated SU, it force closed on me any time I tried to open it, and programs were unable to gain root access. So I restored my Nand backup, but now I'm having a new issue.
Basically, SU (the restored old version) opens fine from the programs menu, and programs I have already granted SU access to (SetCPU, for instance) work just fine. However, any time a new program asks for SU access, SU hangs at a black screen, so I'm unable to give any new programs root access.
Is there an easy way to fix this, or am I going to have to totally wipe/reflash my phone? I tried updating SU in a variety of ways and reflashing the rom WITHOUT a wipe, but none of those attempts fixed the problem.
Thanks.
Did you wipe before restoring your nandroid? And you're positive you flashed the right SU? The one meant for froyo? They always release TWO SU's, one for froyo and one not.
I didn't read the entire first post but make sure you have usb debugging mode turned on... My SU was hanging last week until I rechecked that.

Some versions and ROMs require you to do this before you use anything that needs SU:
Install Android SDK if you haven't already.
Plug in the phone to the computer with USB Debugging on.
Open up a command prompt and navigate to your tools folder.
C:\android-sdk-windows\tools> adb shell
#
# su
(type adb shell, press enter, then type su, and press enter).
Your phone should pop up with the REAL allow/deny screen, without it being all black. Just for the first time.
Hit allow always, and move on.
Then when you want to use Root Explorer or SetCPU or anything that needs root permission, you WON'T just get that hanging black screen. It'll work.
Some ROMs and versions of SuperUser (or maybe something in bin/xbin, I'm not sure?) require you to use the SDK to use ADB shell, to get SU permissions, before you let any other apps get it.
Strange, yes.
Hope that helps.

The command "adb shell" doesn't work at all for me. In PowerShell, it just hangs at "Running script/selection".
Can you help me?
Hi there,
I have a Rockchip RK3188 Tablet with Android 4.2.2, which I need to root ON DEVICE. Actually, the device was already rooted (using a Laptop via the adb bridge), so I already have busybox installed and I have one of my own apps in /system/app. However I managed to delete the su program (yeah great!) and therefore don't have root access any more. I know I can easily root the device again if I connect it to my laptop again, but that is not possible, because the device is at my parent's place and I can't go over there any time soon.
Therefore I want to root the device just with an app. Actually I would only need to copy su to /system/xbin.
These are the things I already tried (without success):
Framaroot (doesn't work, because framaroot does not support Rockchip tablets)
Writing my own app, which contains su in the assets and using this su for temporary root
Using adb (on the device) for a local connection (adb connect localhost), because if I connect from my PC I automatically have root (doesn't work because Android 4.2.2 has increased security on adb)
Start telnetd via busybox and then execute my commands via nc (doesn't work, because I can't start telnetd in a way that it ends up with a root shell)
Any other ideas?
My last idea is, that I could maybe gain temporary root access with the app I already have in /system/app. Basically this would be similar to the Master Key Exploit, except that I do not have to fiddle around with the apk and instead install it normally. However I don't know how to continue from that point. I know, I have special permissions if I have an app in /system/app, but which permissions are that? And how can I use those permissions to make /system writeable (and copy my su file there)?
Thank you for your help,
Tobias

are you rooted check with root checker if yes(as you alredy said)
install super su or super user to gain root acces controls
but iam not sure from your question you are rooted or not or are you trying to root
P.S deleting super su will not unroot you

Root checker says: "Sorry! This device does not have proper root access."
Right now, I am NOT rooted. So the device WAS rooted and then /system/xbin/su was deleted. Meaning: everything else is in place (SuperUser, Busybox, etc.) but I cannot execute anything as root, because I cannot switch the user to root (what su does). Although I am not really unrooted, I cannot do anything any more. So basically I would like to re-root my device.
The goal is to get fully rooted again.

I don't think you can root without any pc
If your phone has recovery just flash the root files :thumbup:

Have you tried looking in /system/bin/su instead of /system/xbin/su
Have a strange one I don't know how to fix. Purchased a Pyle PTBL102BCD tablet for the Mrs. to use basically as an ebook reader (according to About, running 4.2.2). When it came in I started sideloading apps to prepare it for her (I do not have a Google account), and searched on the Net about rooting the device. Found a one-click that worked with a different Pyle tablet, so I gave it a shot.
Now I have root access _only_ through the adb shell. None of the apps (including Superuser.apk itself as tested by updating /system/bin/su) can get root access, yet I have no problem running root through an adb shell - remounted file systems, even performed an su which is the only instance Superuser.apk's log shows. Root access in the shell remains between reboots, so it's not a temporary root.
If the adb shell has root, I _should_ be able to use it to grant access to everything else, and I've followed a few different "manual" root instructions (having different permission settings for su and busybox), with no joy. So long as I connect with a USB cable and type on the Windows machine, I'm god. On the tablet itself...not so much.
I hope that someone with a more intimate knowledge of Android internals can point me in the right direction for achieving root completely. Currently have Titanium Backup and ConnectBot (long java errors when I attempt to su there) installed to test root, Superuser v3.1.3 and su v3.1.1. Permissions on su are -rwsr-sr-x. And the human is confused.
Did you get anywhere with this? I have the same problem. What one-click did you use?

Side note; REALLY hate the new forum software. With all the untrusted Google and Amazon javascript (which my company firewalls), it's a pain for me to even log in let alone post replies. (And I wonder if I'm the only person in the world sick to death of all the unnecessary ajax garbage...)
Anywho, used Kingo, rooted and unrooted a few times, until I finally acquired complete root on the thing. Once I did, I could run Samba, and once that worked, I could more easily transfer files and apks to the tablet.
Still don't understand why it was left in such a...weird...state - having root by default in adb is just a scary thing!
thanks for the information. I tried doing that but I encountered various problems. Eventually, after trying to do it manually, I totally screwed up the device. Now it won't boot.. I still have access to adb. I need to flash this thing. Do you know what the stock ROM is?

No...I can give you the Kernel version info (3.0.36+ [email protected] #48) and build number (rk3168_k11_4.2.2_v20131230), but other than that no clue.
Goodday,
I have been looking into rooting my android device for over a week now and was still not able to find how it can be done for an unidentified tablet.
I have an Allwinner T8 tablet (headunit) that runs oreo 8.1.0, theres no info availlable on this unit whatsoever, all i have is a detailled system information gathered by root checker, i can post the detaills if its required.
I've managed to make a full backup of my device using the adb backup command incase something goes wrong it can be reverted easily.
No custom recovery option availlable to flash.
Is it possible to root my device using the supersu zip without a custom recovery for example with adb using the command "adb flash"?
The most usefull guide for my situation i have come across is the magisk manager installation guide: ht tps://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
This method requires me to have the stock boot image from my device, seeing i don't have root and cant just copy that file, where exactly can i find this file(whats the path to it)?
Is it possible to use adb command "adb root; adb pull ... " to retrieve this file? If not how can i get my hands on this file?
Please help me, i have spend many houres searching google and watching videos but all of wich are the easy methods that don't work for my tablet or require root or a custom recovery wich i cant install... pretty frustrating...
I think magisk manager is the only correct way to go for my problem
Also, if i remount my system or root with read&write rights using adb shell, is that the same as rooting my device?
if i can read and write into the system directory on my device then i should be set.
So what exactly is the diffrence between rooting my device and remounting my device/system as read/write?
anyone??
Like everyone else, I picked this Azpen A743 up at Microcenter for $20. It was advertised as having 5.1, but came with 6.0.1. I bought it to stream music from my Asus router with samba share drive. Other than that, just plan to use Google News, weather app, and light web browsing. Tried a couple rooting methods but no luck. Reluctantly tried Kingo Root, but it never finished the process. (I've read these devices come preloaded with malware, so some more from kingo root won't hurt). From what I've read and searched, there isn't any custom recovery for this tablet. Anyone know how to root it? I did manage from stock recovery to sideload SuperUser.apk, but it doesn't work.
I have USB debugging on, and bootloader unlocked.
Specs are: Allwinner 1.3 GHz A33 4core
The recovery lists the tablet as:
A33_86v/astar_xr819/astar-xr819
6.0.1/MOB30R/20171221
and firmware version v6.0rc3 (I have found references to OxygenOS for that FW version)
If there is not a root method, is there a way to alter/replace the hosts file? I would like to transfer the hosts file from my phone generated by adaway. I have copied my phone's hosts file and tried:
adb reboot download - reboots to OS, doen't seem to have a download mode, but it would almost have to in order to update the FW
adb reboot bootloader - boots to Azpen screen buring bootup, but just hangs
adb push - system read only
adb shell - cp hosts (read only)
adb shell, then su - SuperUser pops up saying ADB need SU access, grant it but nothing happens. can type, but nothing happens.
from recovery, if I mount /system, then device no longer detected by adb.
Didn't try any fastboot commands, scared of losing data, and I don't see anyway to back up the current FW
Also tried the Phoneixsuit software to install apks, but it didn't work
created my own update.zip - 255 error (or not verified even when using various methods to sign the .zip file-Sign-em, Auto-Sign)
Is there a way to create a .zip or apk that is signed that will copy the hosts file to /etc/hosts?
Any advice or guidance would be appreciated.
Have you had any luck since posting this? I'm trying to root the same device, but no luck so far.
Nope. Somehow managed to push Superuser to it, but still not rooted. SU app pops up asking for SU if "adb shell SU", can grant permission, but still nothing. Can't make permission changes to RW. I finally got fed up and tried flashing the wrong firmware to it, but even that wouldn't work. PhoenixSuit, PhoenixProUSB, PhoenixCard would not work to flash different firmware... and no response from Azpen about lollipop firmware or any firmware for that matter. Won't return emails or answer the phone.
I don't know if by pulling the /system folder ,making changes, then using a tool like Dragonface to build a prerooted image would work or not. Can't really do anything without the right firmware for the device.... and I'm not counting on that happening.
This is a good place for info on A33 info and tools:
http://forum.gsmhosting.com/vbb/f906/
I finally got widgets to update after a month of tinkering.... everyday it tells me the SD card is corrupt... other than all of the above, it is a decent little tablet for the $20.
