[GUIDE] Reclaim Reserved Storage (gain ~450MB) - Moto G General

Android reserves part of the storage to make sure everything runs smoothly (sms, call log) if you accidentally fill your storage.
On our Moto G there is ~500MB reserved. It's especially frustrating if you have the 8GB version! You see this free space but the Play Store keeps telling you you can't install a 2MB app ! I recommend keeping at least 100MB (2% on 8GB, 1% on 16GB), but you can probably go as low as 50MB.
I've been looking for a while how to disable this stupid check. All I could manage to find is articles about how to fix Play Store issues, not address this limitation directly. But today I gave it another try and found an article explaining the solution!
NOTE: This mod can be done a lot easier (no command line, no sqlite3 binary installation) using a visual sqlite3 editor from the play store, but I didn't find any free app that do root and I'm not sure if it's against the rules to post links to paid apps?
NOTE2: While it does require ROOT, it doesn't modify the system. If you wipe your data partition the change is gone!
For the time being here's the command line guide:
You will need root and the sqlite3 binary, I took mine on xda here
Connect through ssh or adb shell or open a terminal on your phone and run:
Code:
# sqlite3 /data/data/com.android.providers.settings/databases/settings.db
SQLite version 3.8.6 2014-08-15 11:46:33
Enter ".help" for usage hints.
sqlite> insert into global (name, value) values('sys_storage_threshold_percentage', '1');
sqlite> .quit
# reboot
Note: sys_storage_threshold_max_bytes can be used instead of sys_storage_threshold_percentage if you prefer finely tuned size!
Hope it helps someone

Nice indeed !

Love it!!

I'm experiencing the error no such table found global. I'm on Cm13.1, is there any other table to be used in marshmallow?

Has anyone tried this thing? Does it still work?

You don't need root
Bash:
adb shell settings put global sys_storage_threshold_max_bytes 0
adb shell settings put global sys_storage_threshold_percentage 0
Reset to factory settings
Bash:
adb shell settings delete global sys_storage_threshold_max_bytes
adb shell settings delete global sys_storage_threshold_percentage
Also You can use SystemUI Tuner (System - Storage)

[How To] Enable Non-Market apps on Captivate (consolidated)

(additional CHOWN notes added below. If you are getting "chown: unknown user/group system:system" read them!
Ok, we do have a WHOLE other thread that was made a sticky already, but you need to read the WHOLE thing to get all the properly interesting parts. I'll make sure I keep this OP up to date.
The following methods enable side loading and installing of apps onto the captivate, without the need of a program on a computer attached via the SDK. There are multiple methods, and for the most part, these methods that have worked flawlessly for many users here on this forum. We're just collecting them all in one post for speed and clarity.
Methods that assist in loading applications, without modification to the settings (a.k.a still need a computer attached) can be found at the collective wiki, http://samsungcaptivate.wikia.com/wiki/How_to_Sideload
ALL METHODS REQUIRE ROOT & BUSYBOX:
Root your phone, see http://forum.xda-developers.com/showthread.php?t=725555
Busybox : http://www.appbrain.com/app/stericson.busybox
Please, save a clean, un-altered backup copy of this file. To be safe. Rarely does corruption occur, but if it does, it won't be good.
Method 1: From Win7x64, Samsung Drivers, Android SDK installed.
This method uses the tools you already have at hand, as part of the SDK. All instances in code blocks are run inside of the command prompt. You will need to know where you installed your SDK, and the tools directory therein.
Once rooted, go install BusyBox installer from the App Market/AppBrain etc and run it. It will download and install the latest version for you.
From my Win7x64, with USB Debugging ON. Ensure that you phone is UNLOCKED as it the SU app will ask for permission for 'UNKOWN' in the following command.
Connect to PC, and Eject/Safely Remove the SD card, and "Turn off USB Storage" on the phone.
open command prompt, follow along:
Code:
> c:
> cd \android\tools
> adb shell
$ su
# cp /dbdata/databases/com.android.providers.settings/settings.db /sdcard/settings.db
# exit
$ exit
mount the SD cards to the pc,
"USB Connected select to... ", Mount
mine mounted as H:
Code:
> copy H:\settings.db settings.db
> sqlite3 settings.db
~> update secure set value="1" where name="install_non_market_apps";
1 row updated
~> .quit
> copy settings.db H:\settings.db
Eject the drive, safely remove, etc.
"Turn off USB storage" etc, to mount it back to the phone
Code:
> adb shell
$ su
# cp /sdcard/settings.db /dbdata/databases/com.android.providers.settings/settings.db
# chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
# chown system.system /dbdata/databases/com.android.providers.settings/settings.db
# exit
$ exit
> adb reboot
Bam. Done.
Method 2: with Root Explorer
(courtesy of kirbo20)
This is a pretty easy process. I went in to Root Explorer - dbdata - databases - com.android.providers.settings, copied settings.db to my sd card, edited it on my pc with a db editor changed 0 to a 1 next to non market apps. Copied it back to the original directory, rebooted and installed a non market app.
(added by gotfolk)
again using FF plug in..
Click Secure on the left pane
click on install_non_market_apps
click edit
number 3 states value click there and type in 1. hit ok
(/gotfolk)
Please use caution. If you want to make sure the db save properly open it on your sd card before you copy and replace the original. It should open up as a readable table. If it opens up in a txt editor its corrupt. This permanently enables non market apps. You can not toggle it on and off.
( This is a sqlite3 database file, you can find many GUI editors that will be able to handle the editing, including a FF plugin. Search "SQLite" )
Method 3: with Root Explorer & Sqlite Editor & Terminal Emulator
(courtesy of ice3186)
- Open Root Explorer
- Browse to /dbdata/databases/com.android.providers.settings/
- copy settings.db to the root of your sd card ( /sdcard/ )
- Click on the newly copied settings.db in /sdcard/, with SQLite Editor installed, you can open and edit it here.
- Select the "secure" table, and update the value of 'install_nonmarket_apps' from 0 to 1, and save.
- close out of SQLite editor
- copy the modified file ( /sdcard/settings.db ), and browse back to /dbdata/databases/com.android.providers.settings/ and paste
- confirm the overwrite if asked and then open again to confirm it's been changed.
- open Terminal Emulator
Code:
$ su
# chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
# chown system.system /dbdata/databases/com.android.providers.settings/settings.db
# reboot
- reboot phone.
No PC, no Mac, no drivers, no SDK. Viola.
Method 4: Mac & Android SDK
You will see "[sdcard]" through this method...I don't own a Mac so I'm guessing a bit.
This method uses the tools you already have at hand, as part of the SDK. All instances in code blocks are run inside of the Terminal. You will need to know where you installed your SDK, and the tools directory therein.
Once rooted, go install BusyBox installer from the App Market/AppDroid etc and run it. It will download and install the latest version for you.
From a Max OS X, with USB Debugging ON. Ensure that you phone is UNLOCKED as it the SU app will ask for permission for 'UNKOWN' in the following command.
Connect to Mac, and Eject/Safely Remove the SD card, and "Turn off USB Storage" on the phone.
open Terminal, follow along:
Code:
> cd /android/tools
> ./adb shell
$ su
# cp /dbdata/databases/com.android.providers.settings/settings.db /sdcard/settings.db
# exit
$ exit
mount the SD cards to the Mac,
"USB Connected select to... ", Mount
mine mounted as [sdcard]
Code:
> cp [sdcard]/settings.db settings.db
> ./sqlite3 settings.db
~> update secure set value="1" where name="install_non_market_apps";
1 row updated
~> .quit
> cp settings.db [sdcard]/settings.db
Eject the drive, safely remove, etc.
"Turn off USB storage" etc, to mount it back to the phone
Code:
> ./adb shell
$ su
# cp /sdcard/settings.db /dbdata/databases/com.android.providers.settings/settings.db
# chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
# chown system.system /dbdata/databases/com.android.providers.settings/settings.db
# exit
$ exit
> ./adb reboot
Method 5: Android SDK only
Of course, this also requires root and BusyBox.
From the android sdk tools folder in a command prompt:
note: all linux/mac should use './adb' in place of just 'adb', and place quotes on the echo statement between echo and |
Code:
adb shell
su
chmod 666 /dbdata/databases/com.android.providers.settings/settings.db
exit
exit
adb pull /dbdata/databases/com.android.providers.settings/settings.db settings.db
echo update secure set value = 1 where name = 'install_non_market_apps';|sqlite3 settings.db
adb push settings.db /dbdata/databases/com.android.providers.settings/settings.db
adb shell
su
chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
chown system.system /dbdata/databases/com.android.providers.settings/settings.db
reboot
NOTICE
You must chown the settings.db file and reboot once it is back in its original location. If you do not, you will not be able to alter settings such as WiFi,GPS, default Ringtones, etc. It's also highly likely that you may wish to chmod to 660 (-rw-rw---), so I've tacked that in here and above.
Code:
> adb shell
$ su
# chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
# chown system.system /dbdata/databases/com.android.providers.settings/settings.db
# exit
$ exit
> adb reboot
Chown Note
In the event that you are getting "chown: unknown user/group system:system" please try 1000.1000 as this has been reported to work on several of the samfirmware-released roms that fail with this message.
Absolutely do not use someone else's settings.db unless you specifially make it a point replace android_id with your android_id!
Special Note
Any of these adb comments can be run from Terminal Emulator (Android Terminal Emulator, free) from the su command. I use the ADB here as it is a lot easier to type into. Terminal Emulator will provide you with a shell that is an exact match of the 'adb shell' command, as they both simply provide the shell to you.
Result:
After completing this process you will be able to load non-market apps directly from the APK files, SDK tools, tools such as DroidExplorer and apps such as APKtor.
You will be able to download the APKs directly, and then install from your favorite file browser (e.g. MyFiles(s), Astro(f), RootExplorer($)...)

good stuff!!!
Ok. I can find settings.db with root explorer. i can copy it and i put it in my sdcard folder but nothing is there when i try to find it on my computer. Im trying to use SQlite editor on firefox. Im also on a powermac g4 if that makes a difference. I did download sqlite editor on my phone and I can find where to change the values for installing non market apps but when I change from a zero to a one it denies me. Please help
Ok, so let me make sure I have your process:
- Rooted
- Installed busybox ?
- Installed Root Explorer
- copied settings.db to /sdcard
-- cant see the file when mounted to Mac, thus can't edit with FF plugin
-- SQLite editor for android wont allow access..
(is this the SQLite Editor you used? http://www.appbrain.com/app/com.speedsoftware.sqleditor)
Try installing "Android Terminal Emulator" from the market (http://www.appbrain.com/app/jackpal.androidterm)
- open Terminal Emulator
$ su
# cd /sdcard
# chmod 777 settings.db
# exit
- Open the sqlite editor, and make the change
- back to Terminal Emulator
$ su
# chmod 660 settings.db
- proceed with rest of instructions.

Also, which sqlite app are you using? I'll put that up as method 3 if it works out nicely for you.
fixed a typo in the chown command.. bad copy paste.. bad.. doh.
added method 3 courtest of ice3186
added links to Root Explorer ($), SQLite Editor ($) and Android Terminal Emulator (free) and added the chmod/chown commands to method 3, as they were skipped by accident.
bump** for newcomers, sry.
thanks max for adding the third method. this was by far much easier than the first two methods. I have a hard time getting my mac to talk to my phone sometimes and it was good to not have to plug the lil guy in at all. Worked like a charm
myself and ice3186 are glad we could be of help
If I had accidentally deleted the settings.db how should I go about recovering my phone? Now I have the issue that my phone won't boot past the boot animation and I'm notbsure what to do

Did you make any kind of backup before hand?
You may have to use someone else's settings.db and then do a factory reset.
Depending on how much you've done with the phone I'd suggest deciding on doing a the reboot process for rooting, but choosing to clear data. This may rebuild it, I am not sure.
my dbdata directory is empty.. My phone is less then 2 hours old and i have some market apps installed..

Oh, if it's running, then this folder isn't actually empty.
What are you using to browse this folder?
i followed this guide to a T yesterday when i did this. I used option 1, ADB commands on terminal since i'm a mac and it was super easy, did it in about 5 minutes.
this is just my opinion but i think everyone should try playing with the ADB commands, they're actually really useful and educational to know. and if you should brick your phone, just use clockwork recovery to restore it.
that being said, maybe you should add a disclaimer that when done on a mac, the adb commands require a "./" in front (so adb reboot becomes ./adb reboot). cp, chown, and chmod commands don't need it though (or at least i didn't).

Install 3rd party apps on stock, rooted Aria

Since it took me over an hour to finally get this to work, I figured I would make a new post. (That's a long time to just change a 0 to a 1)
If you want to use your stock Rom but are rooted then this is the easiest way to be able to install non-market apps. I take no credit for this as it is from a post from Attn1 (thanks!).
HTC Sync does not have a choice to add apps in the latest version that I have, I don't know if did before, but I could not get it working. We can all thank AT&T
for this!
Put your phone into Recovery mode.
Goto advanced>mount system and mount data.
Make sure your phone is recognized by adb devices in
your Terminal program.
If not you can use adb kill-server then adb start-server
If you're using linux then you need to precede the adb command
with ./adb
Follow the directions below and you will installing non-market apps
in no time.
NOTE: You MUST have root access in order for this to work
sqlite3 is included in the Android SDK tools, so this would be the best way:
* COMMON
* Enable USB debugging (settings > applications > development > USB Debugging)
* adb remount
* adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
Linux/OS X
* echo "update secure set value = 1 where name = 'install_non_market_apps';"|./sqlite3 settings.db
WINDOWS
* echo update secure set value = 1 where name = 'install_non_market_apps';|sqlite3 settings.db
COMMON
* adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
* Reboot phone and sideloading works. (thanks fluffyarmada)
Yes!!! Thank you, this worked! Rooted, stock HTC Aria 2.2.2.
The only problem I had was that sqlite3 was in the "tools" folders, so I had to copy it into "platform-tools."

[GUIDE] ADB Workshop and Guide for everyone

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.

Great, saves a lot of questions/answers & search
Every new user should read this!!
Thread stuck as valuable reference thread
Just to add, if I may, a little about the permissions...
============================================================
File permissions for Unix... which Android is based, just so those who tinker with the file permissions may know what they are getting into.
============================================================
Use the chmod command to set file permissions.
The chmod command uses a three-digit code as an argument.
The three digits of the chmod code set permissions for these groups in this order:
1.Owner (you)
2.Group (a group of other users that you set up)
3.World (anyone else browsing around on the file system)
Each digit of this code sets permissions for one of these groups as follows. Read is 4. Write is 2. Execute is 1.
The sums of these numbers give combinations of these permissions:
0 = no permissions whatsoever; this person cannot read, write, or execute the file
1 = execute only
2 = write only
3 = write and execute (1+2)
4 = read only
5 = read and execute (4+1)
6 = read and write (4+2)
7 = read and write and execute (4+2+1)
Chmod commands on file apple.txt (use wildcards to include more files)
Command Purpose
chmod 700 apple.txt Only you can read, write to, or execute apple.txt
chmod 777 apple.txt Everybody can read, write to, or execute apple.txt
chmod 744 apple.txt Only you can read, write to, or execute apple.txt Everybody can read apple.txt;
chmod 444 apple.txt You can only read apple.txt, as everyone else.
Detecting File Permissions
You can use the ls command with the -l option to show the file permissions set. For example, for apple.txt, I can do this:
$ ls -l apple.txt
-rwxr--r-- 1 december december 81 Feb 12 12:45 apple.txt
$
The sequence -rwxr--r-- tells the permissions set for the file apple.txt. The first - tells that apple.txt is a file. The next three letters, rwx, show that the owner has read, write, and execute permissions. Then the next three symbols, r--, show that the group permissions are read only. The final three symbols, r--, show that the world permissions are read only.

Thanks, all goes to Adrynalyne
Thanks for the guide. Helped me pick out the stupid stupid mistakes I was making...so just a problem. I'm able to use fastboot easily but I seem to be unable to use ADB still on my windows 7. It says there are no devices and I'm dang well sure I have USB debugging on. Is it because Windows 7 is missing drivers for the nexus one or something else?
wonderful guide. I would like to add it to the guides thread.
Really awesome work, thumbs up.
But we should also take a guide on installing adb with Ubuntu/Linux, which isn't a very difficult thing...

This is good but I have a problem, when I try to remove an .apk file from /system/app it fails and says 'rm failed, Directory not empty'
I have followed exact instructions many time but never succeeded :s any help!!
(I am runnging these commands in device mod)
when I am in recovery mod I get this prompt ~ # and I am not able to enter su mod. how to get rid of this??
Well when the $ changes to # it means you have SU access

Please give us the exact command(s) you entered
Here are the commands I entered after adb shell;
su
mount -o rw,remount /dev/block/stl9 /system
rm /system/app/mytouchmusic-signed.apk
exact message returned is 'rm failed for mytouchmusic-signed.apk, Directory not empty'

Ok i think you need to do a recursive force delete which should be rf but i am not too sure! could somebody please confirm/ correct this?
Well, I don't think so ^^ As he doesn't want to erase a whole directory, but only a file.
What surprises me the most is the returned message... You're trying to delete an apk, and it says it's a directory :/
Could you please give us the output of this :
Code:
su
mount -o rw,remount /dev/block/stl9 /system
ls -l /system/app/mytouch*
Perhaps you don't even need the su and mount lines, but I'm not sure about that, and that can't harm your system ^^

I know he doesn't want to delete a whole directory, but since the apk isn't compressed perhaps android looks at is as a directory and not a file? i don't know since what was returned suggested that it was a directory i presumed it was a directory! :S

[GUIDE][7.1.1] Making The System Half-Writable & Convert The Apps To Be System-Apps

[GUIDE][7.1.1] Making The System Half-Writable & Convert The Apps To Be System-Apps
Okay. This is my first guide. My English isnt that so good. I tried something for my phone. I thought maybe it will helps you too.
HERE IS MY EASY GUIDE FOR UNINSTALL SYSTEM-APPS ON NOUGAT 7.1.1 VERSION 34.3.A.0.244 (AND ALSO MAKE THE SYSTEM HALF-WRITABLE?)(I DONT KNOW MUCH THESE SUBJECTS SORRY)
-Requires
- Version 34.3.A.0.244
- Magisked
- TWRPed
Note: Here is my TWRP and Magisking Guide Here Here Here
Installation
1. First Install
a. Android Terminal
b. Busybox By Meefik
2. Open Busybox and Install.
3. Open The Terminal Emulator. Its just like this
Code:
F5121:/ $
and type "su" just like this (NOT "Su", just "su" with little S)
Code:
F5121:/ $ su
press okay (on your keyboard)
Now this dollar symbol changed the like this #
Code:
F5121:/ #
That was First Step of terminal. Now the second step, type this command carefully
Code:
busybox mount -o rw,remount,rw /system
rw,remount,rw
-These are not dots, These are virgules.(commas)
Type and enter. If it doesnt give any error message just like this "mount: '/dev/block/bootdevice/by-name/system'->'/system': Device or resource busy" or something, congrats you did.
-Now you can delete your system-apps using Link2SD.
-But you cant still convert the u-apps to system-apps using Link2SD!
If you want convert user-apps to system-apps, use Root Explorer.
- User-apps located at root/data/app
- So cut the folder (wanted to convert system-app) from data/app
- Paste to root/system/app
- Restart The Phone
- I know this is manual guide for converting apps but it simple and easy.
(When some apps converted, maybe doesnt work. You have been warned.)
+thanks for the SoNyek for post
+commands from YasuHamed. Thanks. His guide is here

Guide: Tweaking AOSP to Pass Integrity Test and Get Gear App working

Hey S7 Users!
I don't know how many of you have experienced the problems that I have encountered while trying to run AOSP (Specifically Resurrection Remix 6.2.0) on the S7 such as passing integrity check or getting the gear app to work but they have been an issue for me. I'll be putting here what I did to get these things to work that I figured out over time and hopefully will save some people time. And sorry if the format is weird it's my first time making a guide and posting.
The problems that I'm going to address specifically are:
- Passing CTS Integrity
- Getting the Gear App to Work
First off, the CTS integrity. When you first install the ROM, you might find that you cannot download certain apps or that apps don't work correctly. Thats because the CTS integrity is tripped. This is because the Phone does not have a proper build fingerprint since it is a Custom ROM.
To fix this you're going to need Magisk (Link) and Magisk Manager and also Terminal Emulator (Link). Follow the instructions and once installed go into Magisk Manager and you can check that your CTS Integrity is False.
Next go to the download modules section
Screenshot
Then search for Magisk Hide Props Config, install it and then reboot.
Once rebooted open terminal emulator, grant it SU access and type "props"
A menu should appear: Screenshot
Now type 1 and press enter and this should pop up: Screenshot
Next type f then this will pop up: Screenshot
From there select the number that corresponds to Samsung or whatever phone you want although I haven't checked this to see if it works but I don't see why not. Then look and find the one labeled "Samsung Galaxy S7 (8.0.0)" should be 16.
Once you have selected 16(or what ever one you picked) type y and press enter to change the fingerprint: Screenshot
After it is finished it will ask you to reboot. Once rebooted go into Magisk Manager and check that CTS Integrity is now true. Also, go and clear the data and cache of the Play Store and the Play Services. Now you can download apps and use Google Pay
Now for the real challenge the Gear app. This one stumped me for a long time and made me want to just go back to stock. But I kept going and eventually figured it out.
Setting the fingerprint was only the first step because before you could not install it. Now when you open it it'll tell you that you've made unauthorized changes etc. because it thinks that the S7 is on stock firmware but when it checks it sees that it isn't. So what we are going to need to do is change the build.prop to make it look like a different phone. I'll link mine down below if you want it but it is a herolte (S7 Exenos) so keep that in mind as it might brick your system. This will involve some Linux skills.
For this one it is easier if you do it from a computer and then do adb shell. Enable Debugging in the Developer settings and then adb into the device with:
Code:
adb shell
Then
HTML:
su
(Allow it the Super User Access)
Next you have to set the /system to R/W so do that with the command:
Code:
mount -o rw,remount /system
After you have done that type:
Code:
cd /system
And then set permissions on the build.prop:
Code:
chmod 644 build.prop
At this point what you want to do is exit out of the shell (so type exit twice). Now type:
Code:
adb pull /system/build.prop
This will pull the build prop but it goes to different places. I suggest you look up where it stores it as it will vary where it drops it depending on operating systems. For me in Windows it is the following:
Code:
C:\Users\<account_name>\AppData\Local\VirtualStore\Program Files (x86)\MyCustomADBInstallLocation\
Now that you have it simply open it in a text editor and edit the following lines:
Code:
ro.product.brand=htc (change from samsung to htc)
ro.product.manufacturer=htc (also change from samsung to htc)
After that save the file and then go back to the terminal and type(Assuming you haven't moved the file):
Code:
adb push build.prop /sdcard
This will move it to the internal storage since at least for me i could not push it directly to /system
Now do another adb shell and su then type these commands to delete the old one, copy the new one in and then change the system back to read only(This is very important to avoid bootloops!):
Code:
rm /system/build.prop
cp /sdcard/build.prop /system
mount -o ro,remount /system
And then exit out of the adb then reboot the phone. If all goes well then it should reboot and the gear app should work now. Woohoo! That was pretty involved and I'm sure there is a more efficient way to do that (feel free to comment and suggest one) but I can guarantee that it works. Also feel free to ask questions and I can try to answer them. Anyways guys if this helped please hit the thanks button. This took many hours for me to figure out and I hope it all works out for you. Cheers!
