[Vulnerability] Bluestacks root access via adb - Android Software/Hacking General [Developers Only]

On GitHub: https://github.com/KDVB/BlueStacks-ADB-root-access​​Disclaimer​For informational purposes only. The author does not call for further actions. Created to warn users who use this product
Background​ADB (Android Debug Brigde) - is a versatile command-line tool that lets you communicate with a device. The adb command facilitates a variety of device actions, such as installing and debugging apps. adb provides access to a Unix shell that you can use to run a variety of commands on a device.
Research Walkthrough​For default, in Bluestacks, ADB port is open, but we can't to use shell command (output "error: closed")
Searching for information in the emulator files found the following file ".adbcmd" in Root.vnhd image. Path to file "dataFS\downloads". In this file we can see adb commands that we can run without connection to shell
For example, "getprop" command, that gives us information about android propetries
As we can see, interaction with android shell is working. So, I think "if I can interact with unix shell, maybe tryed to use pipe operators" and pwn i can interact with file system, but with shell-user privilage.
As a result i continue my search to find su command to get root access. SU file is in "/boot/android/android/system/xbin/bstk/su". I tryed pipe operator to get root access, but get error and shell didn't open(
After that i tryed list terminator ";" and it works. I get root shell
Result​Bluestacks have this vulnerability and people involved in its development know about it and are engaged in its elimination.

The real test is to see if you can actually do anything. Sure, you've ID'd as root, but will it actually let you change anything?

Thanks for your reply. Actually you can change in current session, but when emulator reboot, all changes remove. If we speak about system folders. In sdcard folders changes save. Sorry, I didn't mention it in the post.
When i searched information on the virtual disk, i found some scripts that build a system. That takes information from .conf files, but that works only for local work. For example, when you using OpenVPN Connect that port still open and you can interact with it.

[HOWTO] Guide to running ADB under Fedora 11 (and equivalent distros)

Ok, I have fedora 11 installed on most of my computers, since i love this distro to death. My big thing was trying to get adb to work. This is my guide to get it to work, for now.
First things first. Navigate to /etc/udev/rules.d as root. Create a rules file called 50-android.rules (touch 50-android.rules). NOTE: You are better off looking at the contents and picking a rules number set other than what is listed. Sometimes udev is picky. For the newbies, so if any rules start with '50', then change the number by one or two, like 51 or 52. Paste this into the file:
Code:
SUBSYSTEM=="usb",ATTRS{idVendor}=="0bb4",SYMLINK+="android_adb",MODE="0666"
Make sure you use ATTRS, not ATTR or SYSFS, since this is a newer updated udev system.
After that, run udevadm control --reload-rules to reload your rules files. Now just run ./adb devices as root to make sure it recognized your HTC dream. I am working on this fix right now so you don't need to be root, keep patient. Now you can adb shell into your device either as root OR normal user, just as long as you start the server as root. This is a permissions problem, and hopefully I can fix this and/or find a fix soon.
I wrote this because i searched high and low through google, and only found a few good parts as far as a fix. Hopefully this helps a few people out there.
Just wondering if this has helped anyone. If not, delete this thread or do whatever with it....
I have adb on my eeepc 900 with f11 I believe this method works too as well. although it says it has been tested with ubuntu, it works pretty well with f11.

Installing The Android SDK
First you will need to download the Android SDK pack .zip archive, once downloaded find a suitable installation location on your machine and extract the zipped files.
Please note: This installation location will be referred to as $SDK_ROOT from now on through this tutorial
Alternatively you can add /tools to your root path which will prevent the need to specify the full path to the tools directory along with enabling you to run Android Debug Bridge (adb) along with other command line tools.
To add /tools:
Linux
1. Edit the ~/.bash_profile or ~/.bashrc files looking for a line that sets the PATH variable.
2. Add the full path location to your $SDK_ROOT/tools location for the PATH variable.
3. If no PATH line exists you can add the line by typing the following:
4. export PATH=${PATH}:<path to your $SDK_ROOT/tools>

It helped me, since the creation of the file my OpenSuSE 11.0 recognizes the phone perfectly
Thanks a lot for your hint.
thanks it helped me. ill be looking forward to getting it to work without root
just use sudo instead
Just a heads up for user's using Ubuntu 9.10, this isn't needed. I connected my G1 to it and ran ADB with no adjustments to udev or anything else.
Pretty much it works out of the box.
Here is my version
download the .tgz file from googlecode
http://developer.android.com/sdk/index.html
sudo tar -xzvf android-sdk_r3-linux.tgz
Click to expand...
Click to collapse
Code:
sudo gedit ~/.bash_profile
heres my bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH=$PATH:/android-sdk-linux/tools
Click to expand...
Click to collapse
logout
login
connect android g1 device via usb to pc
open a terminal
Code:
adb devices
if you cant get a device try it with superuser.
Don't you think that this is all just a little bit excessive?
To make it work in F11, just do this;
Download SDK, extract.
To use, type:
/path/to/sdk/tools/adb
Another option is to edit the /etc/profile and add
PATH=$PATH:/<Path to android-sdk>/tools
This option will allow any user to use the adb tools when logged in or if you
su -
into another user
I wrote a short guide as well for Windows and Ubuntu. Might help others.
Unfortunately, as anyone with a passing acquaintence with ADB knows, the scrolling issue can be a killer. I swear the other day I pressed "up" twice and it composed "rm /sdcard/rootfs.img /sdcard/system.ext2" and executed it. We run Android on our SD's btw.. Was not cool. Instead, I use ADB via telnet and it works beautifully. Here's how:
Code:
adb shell telnetd &
adb forward tcp:9999 tcp:23
Now type this: "telnet localhost 9999"
Enter "root" and hit enter
Finally update PATH: "export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/system/sbin:/system/bin:/system/xbin:/system/xbin/bb:/data/local/bin"
Okay, so 4 lines to enter and you have a "regular, sane" shell connection to the phone and you can actually scroll through history and text without it jumbling the text and executing random code. Enjoy.

WHY would you want to make it *MORE COMPLICATED*??
There is NO NEED for root.
/path/to/adb ...
THATS ALL.
This is kind of funny... i wrote this because i had trouble with it, so i am just sharing my fix...
In case this is interesting to someone:
The fix mentioned in the first post has to be applied to open SuSE x86 and x64 edition to make the G1 work. The external device works without it, but not the adb device.
Thanks again!
Just wanted to come and post that this does work with OpenSUSE 11.2 x86. Did this hoping to get adb to work with my LG Ally and it does. Thanks!
(Still) works for me on 64bit SUSE 11.4.
Before adding this file, I could not access my device with adb, received permissions errors.
Added this file, and I can shell into my device.
Permissions on adb itself was not the problem, it was access to the device when udev found it.
[edit]Actually used the lines from http://developer.android.com/guide/developing/device.html[/edit]

Idea for a very usefull app. Dev's needed

Hello all.
By flashing my device many times, I am always fed up to plug it and remove all the application I don't want, or open the zip file, remove the apk and resign the ROM.
What I have in mind is making a little app that show us all the applications in system/app ( easy) and them when clicking on them just like a adb shell rm system/app/myUnwantedApp.apk.
The browser is easy to program, but the command line is not easy. I tried with eStrongs and Astro, but they cannot remove the apk..
Cam someone help me or teach me how to enter a adb command line in my phone?
Thank a lot.

You can use a terminal emulator application like Better Term etc to run shell commands. There is nothing special about adb.
The command adb shell rm is simply running the shell first and then the "rm" command. Now, depending upon the ROM that you are using, the command adb shell will give you a root shell (or not). In any case, when you use a terminal emulator, simply use the "su" command to gain super user privileges (you have to have "su" and SuperUser.apk installed).
Since you are talking about a custom ROM, I think that root access is implied.
In any case, look at programs like Android Scripting Environment. It allows you to code scripts in an interpreted language like shell script, python etc... In your case simply write a shell script with the desired "rm ...." commands and execute them after gaining superuser permissions and make sure that your /system partition is mounted in rw mode.

GUIDES & FAQs [Android]: ADB Workshop by Adrynalyne and Guide by Captainkrtek

DO NOT POST IN THIS THREAD BEFORE READING THE WHOLE POST
PLEASE ADD GUIDES TO COMMON ISSUES YOURSELVES
To my recollection, the previous WM Guides thread was successful.. so we'll be moving on to android as well - from beginner to pro.
I hope this thread will provide answers to a decent percentage of your questions.
Please hold until guide collecting is finished..
In the meanwhile you are ALL invited to send me links or full guides to add to this thread.. remember, we are all about sharing.
COMING SOON! (in the meanwhile, you've got a great battery life guide at http://forum.xda-developers.com/showthread.php?t=471521 - be sure to thank BruceElliot for it!)
also, if you decide to post a guide, please keep the guide as neat as possible, with a title containing the LEVEL ([BEGINNER], [INTERMEDIATE], [PRO]) and the commonly searched words so that people who look for it can find it easily. (if you can, use the same color (dark orange) and same size (4) and Bold.. for the main title.. tho that's not a must )

[BEGINNERS] Replacing system files using Android Commander
Replacing system files using Android Commander:
(This post was formally based in the HD2's RTL support thread and revolved around our need to replace frameworks)
so:
1. Download the android SDK from: http://dl.google.com/android/android...08-windows.zip
2. EXTRACT(!!!) the android-sdk-windows to c:\
(make sure you extract the dir - not run the setup from inside the zip file)
3. install Android Commander from http://androidcommander.com
4. Connect your device and make sure it's set to Debugging mode in /settings/applications/development/
5. You might have to set a dir containing your adb.exe file. set it to c:\android-sdk-windows\tools\
6. You will see a Total Commander-like interface. you can then copy the framework.jar file to the correct directory (there's no difference between SD android builds and androids in ROM - the system dir will be shown the same way)
a. Yes, you can replace/delete system files while android is running.
b. (for androids running from SD) Any file copied to /sdcard/android/root/system/X will be copied to /system/X in the system file. The sdcard/android root dir is JUST LIKE your root in ROM androids.
c. Make sure you either created a backup or verified a match in any other way before replacing files like frameworks, zimage, modules, etc.. your android might not boot afterwards (I keep all system.ext2 files backed up so that i can restore them incase i screw something up.)
enjoy

This following guide was rewritten by Captainkrtek, please make sure to thank him for it

(http://forum.xda-developers.com/showthread.php?t=879701)
This workshop was held in #android-learning on irc.freenode.net by XDA Member Adrynalyne. All credit to him for this guide, I simply am taking it and turning it into a guide. Here we go!
You can find the raw IRC log here
Good evening folks, and welcome to my ADB workshop. This is by no means a full explanation on the subject, but more of a crash course to help folks get up to speed, and get more from their devices. There may be some things you already know here, so please be patient and respect those who do not.
Reference Files
http://adrynalyne.us/files/How to install adb.pdf
http://adrynalyne.us/files/Using ADB.pdf
So, lets just start with the basics.
What is ADB?
ADB stands for the android debugging bridge and is used for testing and debugging purposes by developers.
However, we like to get more out of our devices, and its a great way to fix things.
Knowing adb can mean the difference between a paperweight and a working phone.
So, to start with, we will look at installing ADB.
Generally speaking, the Sun/Oracle JDK is required to run all SDK functions.
ADB is but one tool in the SDK arsenal.
So, we begin by downloading and installing the JDK. This can be found here:
https://cds.sun.com/is-bin/[email protected]_Developer
Choose your OS, download and install. I recommend that 64 bit users use the regular x86/32 bit version as well.
Moving ahead, we download the Windows sdk from here:
http://dl.google.com/android/installer_r08-windows.exe
Due to already installing JDK, you won't be stopped by the install process.
Now, if you notice, I installed it to:
C:\android-sdk-windows
I did this because it makes things easier when setting up path variables.
I encourage everyone to do the same, but obviously it is not required.
So, this SDK is handy, but is only good up to 2.2. We want the latest and greatest! (Well I do)
So, we navigate to:
C:\android-sdk-windows\
and we run SDK Manager.exe
If you notice in your PDF file for installing adb, you will notice that you can update, and I made a choice not to include earlier sdk versions.
I won't go into full detail on that, but depending on the version of SDK you have, 8 or 9, it WILL make a difference in using adb.
By default, for version 8 adb.exe resides in C:\android-sdk-windows\tools
By default, for version 9 adb.exe resides in C:\android-sdk-windows\platform-tools
We will assume version 9 in this guide
Really, the SDK is installed and adb is usable right now, but in my humble opinion, its not enough
I like the ability to use adb in ANY directory on my machine.
To do this, we edit Windows's environment variables.
Specifically, the system path.
To do this, we click on start, or the orb (depending on OS), and right click on Computer, left clicking on properties in the menu.
If its windows XP, I believe it brings you into advanced system properties immediatly. Vista and 7 need a second step.
On the left hand side, as you notice I have highlighted in the pdf, left click advanced system settings.
Under advanced tab, we left click environment variables...
There are two boxes here.
We are concerned with system variables, however.
So we scroll down the list and highlight path and click edit.
Ignoring all the extra stuff in here, make sure you are at the end of the line, and type
Code:
;C:\android-sdk-windows\platform-tools
The semicolon allows us to separate it
from the previous path statement.
Click ok all the way out.
We now have ADB setup globally. We can use cmd.exe (I use powershell) and no matter what directory we are in, adb is recognized.
If it is not, make certain you entered the path into system variables, and made no typos.
If you installed to a different location, you will need to adjust the path accordingly.
This concludes the section on installing the Android SDK to use ADB.
This next section will be on using ADB, so please open that pdf now.
Now, this applies to any OS, not just Windows.
Well, with the exception of the USB drivers.
I will not go too much into that, but if you take a look at the PDF, it goes through installing usb drivers for the sdk, and how to download them.
Fiarly straightforward, in that rspect.
Now, to setup our phones to use with the SDK and ADB, we must change some settings.
First, we go to menu softkey, then settings.
We scroll down to Applications and tap it.
Under Development, we will check Enable USB Debugging. Please note the SGS phones are different in this respect.
The USB cable must be unplugged before enabling or disabling this setting.
Once this is done, we are now ready to play with adb
One quick note: If you get device not found/conencted, please reboot your phone. DJ05 has a quirk in it where ADBD randomly crashes on boot.
A reboot will fix this
ADBD= ADB Daemon
Ok, continuing on.
Lets look at installing applications. This is also known as sideloading.
Unlike installing from the SD card, it does not require unknown sources to be enabled.
The command for this is
Code:
adb install packagename
This assumes that you are working from the directory where the file is located.
This will install the application to /data/app.
It will also show sometimes useful errors if install fails.
That is not something you will see from the Android GUI.
Now, a lot of us have probably deleted files with apps like Root Explorer. While this isn't really a bad thing, it leaves behind databases and data for the application removed.
This is where the 0kb applicaiton entries come from.
If you take that application entry name, you can uninstall the extra data via adb.
First we go to the adb shell which logs into the phone.
Code:
adb shell
If we end up with a $, we will want admin rights, in many cases. This is not one of them, I don't beleive.
To get admin rights, you want to type
Code:
su
Look at your phone if this is the first time, it may prompt you to allow access. Else you will get permission denied.
If you are not rooted, this will not work either.
Ok, now that we are logged in, we will type
Code:
pm uninstall packagename
where packagename is the name of the 0kb listing.
Now this seems like a pain in the a** and I agree.
HOWEVER
There will be a time where Manage applications crashes when you try to uninstall it from the phone. In this case, a factory reset, or this method is the only effective way to fix the problem.
Moving on.
How many of us have removed system applications or renamed them? Did you know that you can simply disable them from the system?
Code:
adb shell
su
pm disable appllicationname
This will disable it, and the system will ignore it.
This can be seen as safer than deleting or renaming things, but your mileage may vary.
On the other hand, you can also re-enable these applications.
Code:
adb shell
su
pm enable applicationname
Please note: Not all applications will properly re-enable. I believe a factory reset or reinstall of said application will fix the issue.
Also, application names are absolutely case sensitive.
*nix based Operating Systems see the letter 'a' and 'A' as two different things.
when you log into adb shell, you are playing by android rules
Ok, a lot of us tweak and mod our phones and turning off the device to get to clockwork recovery, or battery pulls, or multiple button holds to get into Download mode are troublesome and annoying at best.
ADB can help us here.
Here, we do not need to be logged into the shell
If we want to merely reboot the phone:
Code:
adb reboot
If we want to go to recovery (works well with voodoo5)
Code:
adb reboot recovery
If we want to go to Download Mode because we need Odin, heaven forbid:
Code:
adb reboot download
Its instant. No waiting on animations or anything else.
Its also handy if Android has locked up, but yet still works in adb.
I for one hate taking my case off to battery pull.
So now we move on to pushing and pulling files.
Sometimes, I don't feel like mounting my sd card to copy a file over to my phone.
I can use this command to push a file straight to my sd card:
Code:
adb push filename /pathtodirectoryonphone
So for instance, if I have test.txt that I want to send, I would type:
Code:
adb push test.txt /sdcard/
and there it goes.
Ok moving on
Pushing files can be done to any directory, however, some are protected.
For instance, /system is going to give you a permission denied or a read only filesystem error.
To get around this, the easiest thing to do is push the file to your sdcard, then log into the shell:
Code:
adb shell
Code:
su
We will then mount the system as writable
Code:
mount -o rw,remount /dev/block/stl9 /system
Then we can use something like
Code:
cp /sdcard/test.txt /system/app/test.txt
cp stands for copy
and it requires the path of the file and destination path. The name of the file is optional
When you copy it, you can rename it to whatever you like.
For instance, if we wanted to backup a file
Code:
cp /sdcard/test.txt /sdcard/backuptest.txt
Now, lets assume you do not have busybox installed.
You non rooted users will not.
Then you must use a slightly more complicated command called dd
This is used like this:
Code:
dd if=/sdcard/test.txt of=/system/app/test.txt
if is for inputfile
of= output file
Not every user friendly, but probably one of the safer copy commands.
Ok, moving on to pulling files.
Lets say you want to get a file from your phone, to modify, backup, etc.
To do this, we simply use adb in this manner:
Code:
adb pull /pathtofile/filename destinationname
For instance, if I wanted to backup ADW launcher in system/app
I would do this
Code:
adb pull /system/app/ADWLaucnher.apk ADWLauncher.apk
And it will pull the file from the phone and put it in the current directory.
Like above, you can specifcy where it goes.
pushing files to the sdcard, it seems prudent to talk about changing permissions.
sdcards are typically fat32, which destroys permisisons, and Android is heavily permission based.
So if you push an application to your sd card, then try to copy it to /system/app/ bad things are going to happen, or the app may not even show up.
So in that case, we use something called chmod.
This is used in this manner
Code:
adb shell
su
chmod 755 /pathtoapplication/applicationname
Keep in mind
you dont want to do this while its still on your sd card.
an example
Code:
adb shell
su
chmod 755 /system/app/ADWLauncher.apk
755 is good for applications and script files.
Just a couple more topics to cover.
Lets go over deleting files.
This becomes especially handy for removing rogue applications.
To do this, we must be in the adb shell.
Code:
adb shell
su
rm /system/app/ADWLauncher.apk
You may need to remount system as writable with:
Code:
mount -o rw,remount /dev/block/stl9 /system
That applies when using chmod as well.
So what I did above was delete ADW Launcher from system/app
However, what if I wanted to delete the entire contents of a directory?
Same thing as before, except
Code:
adb shell
rm -f /data/dalvik-cache/*.*
I just cleared my dalvik-cache with that command
very quick, very effective.
If you just tried that, please reboot your phone now
Ok....this leaves us with the final topic: logcat
logcat allows us to log what the OS is doing, and possibly delve information for when things are not working
its quite simple Reading it is another.
To use logcat
Code:
adb shell
logcat
To logcat to a certain file do
Code:
adb shell
logcat > /sdcard/logcat.txt
Now we let the log settle down to a reasonable amount of data coming in and not a wall of scrolling, then start the app in question. When it gives an error, we hit ctrl-C and kill the adb shell session.
This should have captured enough data to see the error. Now, I prepared an example. A user came to me on IRC, and Google Maps was force closing. Clearing data didnt fix it, Clearing dalvik-cache, and fix permissions did not fix it. In this case, the user did not know how to use adb So I had him grab an app called alogcat from the market and email me the log. This is also a very valid method.
this file explains what the problem was, and highlights what to look for as an example.

QUICK FAQ's
sources: Q&A Section, The Weekly Q&A Section by XDA News Writers (thanks guys)
Q: ‘Is there any way to block specific apps from using my data connection?’
A: Try the Droid Wall application.
Q: ‘I read how you can make changes in the build.prop file on my Android device. How exactly do I get to it?’
A: Install ASTRO file manager, browse to /system, long press on build.prop – Edit – Copy. Press on the home icon then Edit icon – Paste. Connect sd card, edit it, and paste it over from where you copied build.prop
Q: What happens if I update my phone? will I need to re-root it and get the ROM again? will all of my applications get erased? If so, is there a way around this?
A: You will lose your root, but not apps if it is just an update.
Q: I just tried to flash a ROM from recovery on my Android phone and got “Verification Failed, Installation Aborted” What happened?
A: Before you can flash a custom ROM the .zip file must be digitally signed in the ROM kitchen, if unzipped and re-zipped it will lose its verification, this happens often using the Safari browser as it likes to decompress .zip’s. Or if your download is corrupted (download the ROM again) it will fail the Verification.
Q - HTC Location Widget shows "map data unavailable"
A - On the widget, click the pin/then click the windows button/click get more/scroll to download maps/download relevant map (care, maybe a big file). Now exit and click onto map, your location should now be visible :)
Q:So, I moved all the apps on the SD, but is still not enough. How can I free some memory? I could delete the cache of the older upgrade or something else?
A:Do you have pictures and videos? If so, check if they are on the SD card and not on your internal memory. Cleaning your cache helps, and try deleting your text messages threads.
Q: ‘What exactly is a kernel and what are the benefits in changing it?’
A: A kernel is a bridge between the applications and the actual data processing done at the hardware level. The kernel’s responsibilities include managing the system’s resources – the communication between hardware and software components. Flashing different kernels gives you different operating speeds, better battery life, the ability to overclock, and more.
Android control other device with IOIO Board.
It use ADB.

A: A kernel is a bridge between the applications and the actual data processing done at the hardware level. The kernel’s responsibilities include managing the system’s resources – the communication between hardware and software components. Flashing different kernels gives you different operating speeds, better battery life, the ability to overclock, and more.

Thank you for your patience and taking the time to answer those questions. I loved your simple and easily digestible format.
There is a note
*nix based Operating Systems see the letter 'a' and 'A' as two different things.
when you log into adb shell, you are playing by android rules

this note is all wrong..
1. linNUX is not *NIX.
2. Mac OS-X is a *NIX OS, it is based upon UNIX, they use their own variant called Darwin. Darwin does not require capitolization.
3. The word should be POSIX. Linux is POSIX compliant and POSIX defines the capitolization standardards

Is there any way to use ADB even though I can not enable USB debugging by the android?
I have an Atrix with soft-brick. How can I restore a file (framework-res.apk) knowing that my USB debugging is off?
I can enable ADB via fastboot?
Thanks!

Thanks for sharing this guild :d, i am new member for reccod
Great job~ Sometimes could be used this.
I'm using Windows 10 RTM and I've set the path, yet I still get the "unrecognized application" error in the command console. What am I missing?
Nevermind, a restart fixed it. Used to be you didn't have to.... sheesh.

Replacing system files using Android Commander:
(This post was formally based in the HD2's RTL support thread and revolved around our need to replace frameworks)
so:
1. Download the android SDK from: http://dl.google.com/android/android...08-windows.zip
2. EXTRACT(!!!) the android-sdk-windows to c:\
(make sure you extract the dir - not run the setup from inside the zip file)
3. install Android Commander from http://androidcommander.com
4. Connect your device and make sure it's set to Debugging mode in /settings/applications/development/
5. You might have to set a dir containing your adb.exe file. set it to c:\android-sdk-windows\tools\
6. You will see a Total Commander-like interface. you can then copy the framework.jar file to the correct directory (there's no difference between SD android builds and androids in ROM - the system dir will be shown the same way)
a. Yes, you can replace/delete system files while android is running.
b. (for androids running from SD) Any file copied to /sdcard/android/root/system/X will be copied to /system/X in the system file. The sdcard/android root dir is JUST LIKE your root in ROM androids.
c. Make sure you either created a backup or verified a match in any other way before replacing files like frameworks, zimage, modules, etc.. your android might not boot afterwards (I keep all system.ext2 files backed up so that i can restore them incase i screw something up.)
enjoy

Help with LG D722
I'm using LG D722 phone and I somehow unlocked bootloader and installed twrp recovery. I backed up Lollipop that's what I'm using and i want to restore custom ROM
I know I need to install Google Apps after installing Custom ROM. But Do I also need to install Modem files on my device ? Because I can't find them on XDA Forums. Please give me a link or something. The help is not just appreciated but seriously needed.
Success. Thanks
Hello, I walk testing one recovery but I'm booting before flashing, the question is, will the recovery feel same when booted vs flashed? I've booted and used to flash a pair of zips but felt very laggy and bugged although did the work right. Thanks

[Q] ADB doesn't work on Mac

When I CD to the platform-tools folder and type
Code:
adb devices
it says "adb: command not found" If anyone could help me that would be wonderful. I am on the Inspire/DesireHD running AOSP Gingerbread. Thanks!
You have two choices. You can either run the command prefixed with ./ (dot slash), which allows for executing an executable in the current directory:
Code:
./adb devices
Or, the other choice (which will be better if you intend to use adb a lot) is to add the platform-tools folder to your path by editing or creating the file .bashrc in your home folder (~/.bashrc).
Let's suppose your platform tools folder is: ~/.android-sdk/platform-tools
Then, you would want to add something along the lines of the following to your bashrc:
Code:
export PATH="$PATH:$HOME/.android-sdk/platform-tools"
Save the file, the run this or log out/in:
Code:
source ~/.bashrc
Et voila, you should now be able to run adb from any folder without issue.
Explanation: adding the new path (folder) to your PATH environment variable tells BASH to include that folder in its search for an executable. The reason $PATH is added at the beginning of the new string is so that your default path does not get overwritten. $HOME will simply expand to /home/your_user_name when BASH interprets it.
GENIUS! IT WORKED! Thank you! Now, one more question- how do I get superuser privileges using ADB? (device is rooted, of course)
No problem.
On my G1 you were root as soon as you adb'd in. Just tested on my Defy and '$' - shocking. So once you have run adb shell, just run 'su' (without quotes of course) and accept the permission on your phone screen as usual for root programs and you should be good to go.
Sorry to keep asking questions, but when I typed
Code:
su
into adb, it asked for a password. No popup on device screen. I do have superuser installed on the device.
That is odd. I'm not sure why that would be. I'll see if I can think of something though. Hopefully someone else can make a suggestion.
Thanks! You have been very helpful.
Don't think I can hit the thanks button from the app, sorry

Is there any version of ADB rewritten in C++?

Yes, the question I'm asking is in the title. Context: I want to use certain adb commands (such as shell) to connect and get some status of the BlueStacks emulator. However, using the system command in C++ requires the platform tools to be put in the same directory as the C++ program, which is kinda large in size if I wanted to distribute it.
Don't know of any.
