Hi,
I have a Asus Nexus 7 with the following characteristics:
Android Version: 6.0.1
Kernel Versión: 3.4.0-gae95f7e-dirty
Build Number: MOB30X
I installed NetHunter in it.
I have problems with the OTG conection. I tested 3 type of OTG cables and none of them work.

}
I tested with a ALFA AWUS036H and CROTA2000MW. In addition, I tested with different USB drives, formatted on FAT32 and NTFS.
Besides, I tested with a lot of OTG media manage apps, even Nexus Media Importer app.
Why is it happening this? How can I fix it?
Thank you.
UPDATED:
Recently I bought another OTG cable but in this case with the possibility of adding power supply, but it doesn't work either.
UPDATED 2:
I tried changing init.usb.rc fromde root directory of my Nexus 7. For that, I downloaded this file from the following source:
rootdir/init.usb.rc - platform/system/core - Git at Google
To copy this file to root directory of Nexus 7 and change its permissions, I used adb, but I needed to install "adb insecure" app in the device:
[2014.11.10][ROOT] adbd Insecure v2.00
adbd Insecure lets you run adbd in root mode if your device is rooted. (Note that if you are running a custom kernel, it is likely that it already implements this functionality) If you are running a stock (made by the phone manufacturer) kernel...
forum.xda-developers.com
I installed the app and I executed the following adb commands frommy computer:
Code:
adb shell mount -o rw,remount /
adb shell su -c "cp /sdcard/Download/init.usb.rc /"
adb shell su -c "chmod 646 /init.usb.rc"
adb shell mount -o ro,remount /
The file was copied and its permissions was changes succesfully but when I rebooted Nexus 7, the original file returned with the same permissions.

hi firends
How do I know that my phone (legend) is rooted or not?
what are Symptoms for a rooted phone?
Enable usb debugging, install driver, open cmd, type adb shell and press enter. Then type su and if you get this # you are using a rooted rom. If it says access denied you are not.

If you haven't even installed ADB I don't know how you would think your phone is rooted? Did you buy it used?
Anyways. Download this ADB. Unzip to c: and run adb.exe shell from a cmd in c:\android-sdk-windows\tools
But make sure you install the driver first.
Go to Settings, Programs, Development and Tick Off "USB Debugging". Then when you connect your device to your computer it ask for a driver. It can be located in the android-sdk-windows folder under usb_driver.
thanks Liquid211 very much!

I have no such folder under "android-sdk-windows". I only see "add-ons", "platform" and "tools"...
just try a app that needs root rights.
for example many screenshot apps need su.
another way would be to look if u ve got the superuser app in ur app menu.
and ofcause a terminal like program could help to indicate if uve got root rights.
Simply download a terminal emulator from market and type 'su'...

What's up! I successfully rooted my Nexus S i9020T 2.3.4 Thanks to the many links in these forums! THANKS! Now, I downloaded the BT5 ARM img , got everything pushed to the phone. Then in Terminal emulator -
Code:
cd /sdcard/BT5
sh bootbt
Returns
Code:
mkdir failed for -p, File exists
Loop device exists
ioctl LOOP_SET_FD failed:
Bad file number
mount: No such file or directory
mount: No such file or directory
mount: No such file or directory
net.ipv4.ip_forward = 1
bootbt: cannot create /data/local/mnt etc.....
I can post the rest if needed.
I seen the other threads where the bootbt had to be modified but I haven't seen anything specific for the Nexus S. Perhaps I should use the modified BT5 ARM img? Any help is appreciated thanks in advance.
Update! BT5 ARM Nexus S
So I used the modified BT5 img and followed the instructions here.
http://forum.xda-developers.com/showthread.php?t=1074169 (not allowed to post there yet!)
I run sh installbt.sh and that seems to go ok.
I get errors at this step.
Code:
to use your BackTrack you can use following commands.
startbt <- mounts and prepares the system for usage.
stopbt <- unmounts and free up all resources.
bt <- a command line version of BT chroot.
When I run startbt I get this
Code:
mknod: /dev/block/loop: File exists
moun: mounting /dev/block/loop254 on /data/local/bt
failed: Device or resource busy
mount: I/O error
mount: I/O error
mount: I/O error
startbt: cannot create /data/local/bt/etc/resolv.conf: I/O error
startbt: cannot create /data/local/bt/etc/resolv.conf: I/O error
startbt: cannot create /data/local/bt/etc/hosts: I/O error
chroot: can't execute '/bin/bash': Input/output error
Any help is appreciated!
Did you check your ROM for EXT2 support?
sounds like you are trying to run Linux as the OS in the phone?
have you tried the guide on how to install ubuntu into your phone?
http://forum.xda-developers.com/showthread.php?t=907760&highlight=ubuntu
the original image you flashed is wrong it's for the wrong phone
this is a Nexus S not a Sony Xperia
Waiting for *how to*...
just founded that http://mayaseven.blogspot.com/2011/05/backtrack-5-on-my-android-phone-nexus-s.html
its posible.
Thanks! I'll keep an eye out for it.

my rom doesn't have support for mounting ext2 file systems so i can't use this until i find one that does.
alright follow these steps and you good to go
mounting sd card via command prompt (via adb)
1) go to your's phone's file manager
2) create a folder named external_sd in /sdcard/ (you have to make this folder to mount sd card in /sdcard/ !!!
3) inject this command in cmd (adb)
Code:
su
mount -o bind /mnt/emmc /sdcard/external_sd

then inject this code in terminal
Code:
busybox mount --bind /mnt/emmc /mnt/sdcard/external_sd
after mounting sd card to /sdcard/external_sd
done ......... enjoy
great! gonna try it! this is one of my reasons for not being in aokp/aosp, 'cause i've linked to much files with directory bind from sdcard to external, so i would have to move them back to internal sd card to re-bind them sdcard- to emmc, let you know if it works, btw, do i prompt this commands with the phone on or in recovery? I'm a noob when it comes to adb

1) you can do it when you phone is on
2 ) you have to inject this code after every boot (due to nand suff )
3) just download terminal form my attachment and do it
BTW you can try this method to add this script to boot http://www.xda-developers.com/tag/samsung-vibrant/

I tried to bind emmc to external_sd weeks ago.
The problem is that I couldn't get the script working under init.d. Probably the kernel I was using was the problem who knows.
I used gscript and ran the script at boot with su permission.
Also I suggest you to use this http://forum.xda-developers.com/showthread.php?t=1410262

Hello Friends~!
I decided to play with some forks of android and chrome os in vmware this week, it was a lot of fun!
A problem I would like to create a solution for, is the inability for vmware tools to install natively.
Here is a toolset I prepared called "droidvmtools" DOWNLOAD
I was able to create this toolset based off of the prelGlibc25 Linux iso that came with VMWare, that is stored in Windows in this directory:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If you care about the extra steps added to "droidvmtools" I tried to document that process HERE
This exercise is performed using this Prebuilt copy of PrimeOS for VMWare DOWNLOAD
In theory, this method should work on other android images with root access, then likely fail as this example does at the end.
INSTALLATION:
Obtaining the perl binaries:
In termux run the command
Code:
pkg install perl
Then in Root Explorer, go to
Code:
/data/data/com.termux/files/usr/bin
and copy the perl binaries.
Now paste the binaries to:
Code:
/system/bin
To install the Toolset:
Extract droidvmtools and paste it to the root file system. The video goes over this step at 2:34 if you need reference. ( I also used my yt channel to easily dl the tools youtube.com/@jennn/about the tools are there if no usb)
Open a terminal emulator and type:
Code:
su
chmod 777 -R /droidvmtools
Then in Root Explorer, open droidvmtools, select all, copy, and then paste the contents to the root file system
You will be prompted with this message, select these options:
Now when you type:
Code:
perl run.pl
The tools are able to start installation but they crash at this part:
This is the part I am stuck on. I had never heard of recursion until this happened..
Here is a PASTEBIN dump of the code, maybe someone is able to look and see why this would be happening?
This thread is in preparation for a megathread I want to make. If you want to preview some of the images early see HERE
PLEASE NOTE:
I Understand that "Vmware Tools is not supported" in Linux let alone Android, blah blah. Let's try!
I also already know about and have tried every emulator in existence... So Please! Let's refrain from "just use x emulator", this is about problem solving.
I want to get virtual device with root, Google Apps and writable system. Optionally pass SafetyNet checks. Preferably, based on ARM image because I run it on mac m1.
I tried to create a virtual device using Android Studio Emulator.

I am able to successfully install Magisk root using rootAVD - https://github.com/newbit1/rootAVD
Spoiler: Magisk screenshot
But I'm not able to remount /system writable.
Usually, I do
adb root
adb remount
But after executing `adb root` - I get error `adbd cannot run as root in production builds`
Also tried:
adb shell
su
mount -o rw,remount /
But getting error `'/dev/block/dm-0' is read-only`
I tried adbd-Insecure from https://github.com/wuxianlin/android_tools/blob/master/adbd-Insecure-v2.00.apk
But getting error "Could not patch adbd !". Which is expected, since this module is from 2014...
Spoiler: Error screenshot
Also tried such apps like Root Browser and FX File Explorer with no luck.
I also tried to create devices based on images without Google Apps preinstalled (without Google Play label) on Android 12 and 11. But then I have trouble installing Magisk OpenGApps on it. https://sourceforge.net/projects/magiskgapps/
It seems to be installed successfully, but Chrome is constantly crashing, and Google Play says "This device isn't Play Protect certified"
Spoiler: Android 12.0 OpenGApps Error
My main goal is to get rooted, ARM Android Emulator with fresh Android version and writable /system. I know there is Genymotion with ARM translation and Android 9.0, but it is slow, Mac M1 is not supported and old Android.
Any help would be appreciated.
