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.

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.

This concludes the guide from Adrynalyne, there will be more workshops such as this one in irc.freenode.net #android-learning.
Thanks to everyone in #samsung-fascinate !
Reserved for possible extension of topic
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 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

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

Using the amazing overclock module made by Tiago Sousa http://code.google.com/p/milestone-overclock/ , it is possible to modify the frequency tables on the motoACTV.
I'm not responsible for what you do to your device. This is potentially dangerous.
Extract the attached overclock.ko in some folder of your computer and open a command line in that folder. You need to have adb installed.
Issue the following commands:
Code:
adb remount
adb push overclock.ko /system/lib/modules/
adb shell insmod /system/lib/modules/overclock.ko omap2_clk_init_cpufreq_table_addr=0xc0049150
adb shell 'echo "0 1000000" > /proc/overclock/freq_table'
adb shell 'echo "1 800000" > /proc/overclock/freq_table'
adb shell 'echo "2 600000" > /proc/overclock/freq_table'
adb shell 'echo "3 300000" > /proc/overclock/freq_table'
adb shell 'echo "1 300000000 20" > /proc/overclock/mpu_opps'
adb shell 'echo "2 600000000 30" > /proc/overclock/mpu_opps'
adb shell 'echo "3 800000000 45" > /proc/overclock/mpu_opps'
adb shell 'echo "4 1000000000 45" > /proc/overclock/mpu_opps'
adb shell "echo 1000000 > /proc/overclock/max_rate"
adb shell "echo 45 > /proc/overclock/max_vsel"
This will create 4 frequency steps:
300MHz. This is the minimum we can get with the current kernel.
600Mhz. This is the stock highest speed. Now the voltage is lower.
800Mhz.
1Ghz.
Now, you can use a program like setCPU http://forum.xda-developers.com/showthread.php?t=505419 to set the maximum and minimum speeds.
Enjoy
On this command (after copying and pasting your commands above):
Code:
adb shell 'echo "0 1000000" > /proc/overclock/freq_table'
I get a return of:
Code:
The system cannot find the path specified.
I tried next to re-run:
Code:
adb shell insmod /system/lib/modules/overclock.ko omap2_clk_init_cpufreq_table_addr=0xc0049150
but it failed, because it already exists.
EDIT: I believe they should be like this:
Code:
adb shell "echo '0 1000000' > /proc/overclock/freq_table"
adb shell "echo '1 800000' > /proc/overclock/freq_table"
adb shell "echo '2 600000' > /proc/overclock/freq_table"
adb shell "echo '3 300000' > /proc/overclock/freq_table"
adb shell "echo '1 300000000 20' > /proc/overclock/mpu_opps"
adb shell "echo '2 600000000 30' > /proc/overclock/mpu_opps"
adb shell "echo '3 800000000 45' > /proc/overclock/mpu_opps"
adb shell "echo '4 1000000000 45' > /proc/overclock/mpu_opps"
EDIT 2: That didn't work... the frequencies aren't in setcpu, even after re-detecting speeds.
can you try this command?
Code:
adb shell grep omap2_clk_init_cpufreq_table /proc/kallsyms
It should return a number, and this number is the one that has to be used for the insmod.
I haven't updated my MotoActv in a while and maybe the kernels have changed.
Code:
C:\Users\Owner\Desktop\MiniADB>adb shell grep omap2_clk_init_cpufreq_table /proc
/kallsyms
[B]c0049150[/B] T omap2_clk_init_cpufreq_table
There was no error when running the insmod the first time, it went through successfully, just the next several lines, and then no change at the end, even after a reboot and re-checking the frequencies in SetCPU.
You are right about the commands, for windows, you have to use this:
Code:
adb remount
adb push overclock.ko /system/lib/modules/
adb shell insmod /system/lib/modules/overclock.ko omap2_clk_init_cpufreq_table_addr=0xc0049150
adb shell "echo '0 1000000' > /proc/overclock/freq_table"
adb shell "echo '1 800000' > /proc/overclock/freq_table"
adb shell "echo '2 600000' > /proc/overclock/freq_table"
adb shell "echo '3 300000' > /proc/overclock/freq_table"
adb shell "echo '1 300000000 20' > /proc/overclock/mpu_opps"
adb shell "echo '2 600000000 30' > /proc/overclock/mpu_opps"
adb shell "echo '3 800000000 45' > /proc/overclock/mpu_opps"
adb shell "echo '4 1000000000 45' > /proc/overclock/mpu_opps"
adb shell "echo 1000000 > /proc/overclock/max_rate"
adb shell "echo 45 > /proc/overclock/max_vsel"
Do not reboot! This changes are not save anywhere yet. It's a bit dangerous because the system will not boot if you put wrong values in there. I'm leaving this for later.
Good work, however the changes are not persistent to reboots. I put them in init.goldfish.sh but still not persistent. When doing it from shell, the changes are there in SetCPU, just not after a reboot. Maybe we could script it somewhere else to start at reboot...
Regards...
I added init.d to the /system/etc folder and added my script - still nothing
I added the script in other shells but still nothing...
I heard that SManager will boot scripts at logon, maybe this is the way to go?
There are a few scripts that are launched by init directly. One for the keyboard, one for preinstall, etc.
Try adding the insmod and echo commands to one of those. I'll test this later and post about it.
I amended the one for the keyboard, no dice. I am going to try again though... keep you informed.
init_prep_keyboard.sh keeps reverting back to what it was before amendments. I am sure that I verified its permissions prior to reboot, it just went back to what it was before and deleted the .BAK file too, wierd.
Peace
Working Solution...
I've tested the method above and it works perfectly.
But as mentioned, the script has to be executed upon every reboot.
Working Solution !!!
I've tested this and it works 100%
- Dump boot.img from watch.
- Extract and decompile boot.img
- Create overclock.sh and put it in etc folder from boot.img
- Write entire script in overclock.sh
- Open init.rc from boot.img
- Add exec /system/etc/overclock.sh in init.rc
- Save changes to init.rc
- Repack boot.img
- Push modified boot.img to watch via fastboot
- Restart watch.
Consider adding overclock.ko in system.img
Overclock is now permanent !!! Even after reboot :-D

Can you possibly make a patched boot.img for us?
tansoftware: This is no easy task on a windows box... I will try on Fedora...
a detailed walkthrough would be superb! i.e. How-to? Otherwise GIYF
Peace
EDIT: This ain't easy in linux either...
If you could post your modified Boot.img, that would be killer!
What bash shell did you use upon init.rc? Could you at least share that with us?
dproldan: This thing WIZZes at 1Ghz! If there were just an easier way to make it persistent across reboots... but what a difference.
I posted on the other motoactv thread a very easy way to overclock.
You need android overclock and rom toolbox pro (maybe the free version works I have no idea)
1. Open android overclock select advanced/custom.
2. Scroll to bottom and select apply preset. This gives you four slots 350, 500, 800, 1000.
3. Open rom toolbox pro, performance, cpu control.
4. Slide the bar to desired speed. You can also set profiles in this section to clock down to 350 while the screen is off etc.
I was able to apply at boot etc and haven't lost the overclocking settings. With cf-bench my score went from 1504 to 2370. You can probably apply settings beyond the slots listed above but you will need to increase the voltages in android overclock. I haven't had time to try it. Another microsoft certification exam this week.

a detailed walkthrough would be superb! i.e. How-to? Otherwise GIYF
Peace
EDIT: This ain't easy in linux either...
If you could post your modified Boot.img, that would be killer!

I can't share my boot.img at this time as it is highly experimental and could easily & un-reversibly brick your watch. My boot.img contains a modified bootstrap.bin that flashes upon boot and forces Android to boot from the built-in MMC instead of internal nvram. Extremely buggy at this stage with several crashes but I'm no longer limited by the 256mb ram on the watch. Hopefully after the bugs are ironed out, we can all enjoy full 8/16 gigs of space. This trick was taken from the nook color modified boot code.
As for how to embed the code into your own boot.img, I believe @Prack posted a simpler cleaner method to overclock the watch. If his method does not work as explained, I'll provide a more thorough explanation of my method.

My guess is he's talking about a swapper2 or some other swap file. It helps but it by no means replaces having more ram. I was on a droid 1 for years and the biggest issue with that phone was the ram/internal storage space. I used swap and 2nd sdcard partitions to make up for it. I'm guessing he's doing the same thing with the watch. Would be interesting to see if he gets any actual improvement.
any more news on this?
permanent settings for the overclock
Attached is a modified "loadpreinstalls.sh" file that will load the module and apply the settings at boot.
Be careful with this, it can prevent your device from booting, requiring a full system reinstall to bring it back.
so, download the overclock.ko from the first post, download and extract this loadpreinstalls.sh to the same folder in your computer and issue this commands from a terminal:
adb remount
adb push overclock.ko /system/lib/modules/
adb push loadpreinstalls.sh /system/bin/
adb shell chmod 755 /system/bin/loadpreinstalls.sh
adb reboot
Now you can use SetCPU to choose the speeds you like and make its changes permanent.
This is working fine for me with the current MotoACTV system releases, it could be broken for some older versions.
Enjoy
This sounds like an awesome application - any way to make it easier for the lay (er) people that know just enough to be dangerous?

How about this. I just wrote a simple windows install script and included all of dproldan's needed files, so all you have to do is unzip this to your desktop and run "runme.bat".
Pre-requesites:
-ACTV must be rooted
-ACTV must be plugged into computer and turned on normally
Called it "dproldan_overclock".
Even included the ADB drivers.
I have replaced some fonts on the nook and everytime at some point, i get issue with it.. it does not boot anymore... and every time i need to do a factory reset, re-root. Is there steps/precautions i need to be aware when replacing fonts on the nook or adding apps in system/app??
I have an htc desire rooted and i have never had issues like that on it; i have replaced fonts, edited files like build.prop or key mapping, added/deleted/renamed apps in system/app and i never had a single issue... maybe the nook is different i don't know
To answer your question, no, it's not dangerous.
Linux doesn't care at all about fonts.
So if you have a problem with fonts, use ADB and logcat and actually figure out what the problem is.
Even with flashing dots, ADB and logcat (and dmesg) work.

adb does not detect the nook while it is booting... it only detects when it's booted or when i use cwm
Well, apparently you are bashing some non-font thing.
How are you copying over the font?
Are you using some wonderful "Insta-Mega-File-Masher-Omatic"?
Which font are you replacing?
Stick to basics.
Get your Nook working with 1.2.1 since that is where you should be.
Get ADB working.
Remount /system r/w, adb reboot, still working? Yup.
Remount /system r/w, adb push your font to /system/fonts/temp.ttf, adb reboot, still working? Yup.
Remount /system r/w, then:
Code:
stop
mv whatever.ttf old.ttf
mv temp.ttf whatever.ttf
reboot

I am replacing Caecilia, HelveticaNeue and Trebuchet.... i using adb push to replace the fonts .. i use these commands
adb shell
#su
#mount -o rw,remount /dev/block/mmcblk0p5 /system
adb push myfont.tff /system/fonts
adb reboot
sometimes, every fonts is replaced properly... and everything is alright.. sometimes, replacing the 3rd font and i reboot .. i gets locked.. sometimes it's the 2nd font, it's random.. or sometimes i push an app to system/app.. everything is alright... then i push the same app, it does not boot.. it's all random
how do you activate adb while booting... adb does not detect my nook while booting...
A comment; I have done some playing around with fonts over a year ago and if I recall correctly, the system needs fonts files with names Caecilia, HelveticaNeue and Trebuchet. You can rename other font files to have those names, but those names must exist.
Next, a question; Is it possible that the font files you are attempting to use are so big that they are filling up the file system?
Filling up the partition was one thing I thought of, but since /system is normally ro that didn't seem like it could affect anything.
Do a df and see what space you have left.
How big are the files?
If you are trying to make this do Chinese, just replace one file.
Linux doesn't use fonts.
Android only uses the Droid fonts.
Opera Mobile will use DroidSansFallback.ttf
ReaderRMSDK.apk uses the rest of the fonts.
I can't figure out how to delete some of the system apks off my rooted Nook Simpletouch. Running 1.2.1, and Nootered it. Tried to ADB uninistall Phone.apk, but it just reports failure. I could use some help.
/system is usually read-only.
To make changes in its content you need to remount it read/write:
Code:
stop
mount -o rw,remount /dev/block/mmcblk0p5 /system
The stop is to be on the safe side, it stops the android subsystem.
After you are done making changes it's best to:
Code:
reboot

Just rename them. add ",bak:" to the end or similar. This will disable them, and if you notice instabilities because of getting rid of them you can just remove the appended extension. If everything runs well, you can then delete them with no worries.
I've renamed some of the recommended ones and have an error that comes up. "A problem has occurred, contact support". I need to figure out what is causing that to happen. its annoying but doesn't seem to be an actual problem.
What does "mmcblk0p5" represent?
mmcblk = multimedia card block device, 0 = first device, p5 = fifth partition
Thanks Renate, but It's not working. In order to rename or delete an apk off my Nook simpletouch, would someone please give me step instructions? I feel I'm missing something.
Code:
stop
mount -o rw,remount /dev/block/mmcblk0p5 /system
cd /system/app
mv BoringApp.apk BoringApp.bak
mv TediousApp.apk TediousApp.bak
reboot
And don't tell me that you have no boring or tedious apps!
The advice here is correct, better to rename sysapp extensions (.bak or .ap_) than delete as some might be needed by future apps/sys hacks/kernels. For those who can't adb by cable or keep it up wifi-wise, this is the easiest way even easier than root explorer:
https://play.google.com/store/apps/details?id=com.ghisler.android.TotalCommander
for sys or user app removal if you have to and can't use adb or even total commander, but then you shouldn't if not knowing sys file structures (I use Pro version, for removing many apps i just tested in a batch, sorted reminder):
https://play.google.com/store/apps/details?id=com.jumobile.manager.systemapp
I renamed talk telephone music audio etc apks on nst but Gallery is the only one I removed on all android devices & nst as it's just nasty which has never been missed by later hacks and quickpic is much better anyway:
https://play.google.com/store/apps/details?id=com.alensw.PicFolder
I created another directory under /system called archive. I move apps I don't what to use and fonts I change into /system/archive then I can just move them back if I have issues.
This still isn't working. My commands keep getting rejected. It isnt allowing stop to work. Also, I tried "adb cd /system/apps" and when that didn't work, I tried
"adb shell"
"#cd /system/apps"
No dice.
EDIT: Got it. needed to call it shell instead of adb. I also accidentally wrote "apps" instead of "app".
I've now tried in several ways to change /system/build.prop (phone rooted) but I had no luck.
Method 1: BuildProp Editor
I've tried using this app to change the file, the save succeeds, but after rebooting, the "original" file is restored and the changes are lost.
Method 2: Remounting the filesystem
I've tried remounting the filesytem:
Code:
$ adb shell mount
/dev/block/dm-4 on / type ext4 (ro,seclabel,relatime,block_validity,discard,delalloc,barrier,user_xattr,acl,i_version)
...
Code:
$ adb shell su -c mount -o rw,remount /
$ adb shell mount
/dev/block/dm-4 on / type ext4 (rw,seclabel,relatime,block_validity,discard,delalloc,barrier,user_xattr,acl,i_version)
...
After making my changes, if I try to remount with ro access, it fails. After rebooting the changes are lost again.
Method 3: Modify system.img
I've tried changing the file in the system.img, repacking the super.img file and flash it as single AP file, same result, the changes are lost. I've tried to decompress the super.img and remount it (just to check the changes were still there) and indeed they were.
What am I doing wrong?
Is there any way to achieve this?
I've found a good description of how the system and Magisk work:
- https://topjohnwu.github.io/Magisk/details.html
- https://topjohnwu.github.io/Magisk/guides.html
hello, i am trying to modify build.prop to disable knox and enable multiuser but changes are not persistent, have you found a solution with magisk?
use notepad ++ to modify buildprop on pc. connect phone while off and while phone is booting push file to phone (repeatedly) theres a small window where you can inject during boot...takes awhile sometimes to hit it right. ive dont it on samsungs and lg.
