Moving apps from SD (ext2) to internal memory? - G1 General

I have an 8GB class2 microSD card. I am currently using JACHero r1.4. I don't mind keeping large apps on the SD that I don't use very often, but I want to move my most used applications:
ASTRO
Browser
(Rosie Widgets)
Twitter clients
Opera Browser
DOOM
And anything else that is running in background constantly, like Gmail and IM.
Is there a way to quickly move these from "/system/sd" to "/system/app" without a command line? I tried using ASTRO to move them, but ASTRO doesn't request root privileges, so it can't complete the task. Is there a root file manager I can get? Or do I need to use ADB or Terminal to move them independently?
If I do need ADB or Terminal, show an example.
P.S.: I know I will need to move the .apk and the .odex files together.

I believe this should do it for you:
$su
#mount -o rw,remount /dev/block/mtdblock3 /system
#cp /system/sd/app/name of app /data/app_s
#rm -r /system/sd/app/name of app
That should do it for you, by the way it would be nice if you could work a please into your request for assistance so that it doesn't sound like a demand

if moved like that will it keep the saved data from the app, for example high scores in games?

Where does G1 Store the .apk downloaded via marketplace?

Where does G1 Store the .apk downloaded via marketplace? Ive been using linda file manager to go through all the files but i cant find where it puts them.
/data/app & /data/app-private
when i navigate to that location, nothing shows...just blank. How do i see the contents?
when i got to /data its blank...no other folders....
File Managers don't run with permissions to view /data, so it will show as blank. To view in Terminal Emulator, use su to get superuser access, then you can view the contents of /data with ls.
i thought that was what Astro was for to backup your apps to sdcard so you can copy them to your computer...if im wrong please correct me...i mean when i try it it force closes.
Has anyone found out yet how to run a file manager with root priveleges? If not, I may look at the source of OI File Manager and check out if it just uses the basic commands like ls and cp and try adding a su right before the very first ls command.

Can't delete Apps (A2SD)

Hi,
Ive got a problem. Yesterday i did the update from Dude 1.1 to 1.2, first without wiping, but then the G1 reboot when i want to download an app.
So i wiped it and it works fine. INternal Memory is 355MB free.
Today i wanna delete the APP SMS/MMS because i use chompSMS, but the G1 says that it cant delete. ("Uninstall not successful" "SMS/MMS could not be uninstalled")
So what could i do?
Thanx for ya help
if im not wrong in saying this, the stock sms mms program needs to be on the phone. chomp doesnt get your messages
it gets them from the stock messaging app.
Not sure what you're trying to uninstall (haven't heard of an app called SMS/MMS). However, if you're trying to remove the application "Messaging", you can't. Just disable notifications in the Messaging program and use chomp as the default.
Its the same with this Amazon Mp3 app, i cant uninstall it, what do i wrong? Or how can i get this app off my phone( dude 1.2 full)
You can't uninstall those programs..

If you are using a G1 build, its in /system/app. Remount the system partition and delete it from that directory.
Yeah great, thanx for ya help.
But now I now i'll gonna be beaten for that question, but can you explain me what you mean with 'remount the system partition"?
I've looked it up with ASTRO Filemanager and its really in /system/app, but i cant delete it from there, if i want to it says again "error deleting file".
Just searched a bit around and found the remount command that i know from a2sd, so i think i have to go to Terminal at G1,
#su
#mount -o rw,remount /dev/block/mtdblock3 /system
#rm com.amazon.mp3 /system/app
Is this right? So then i'm gonna eating my shoes But i think it isnt so i ask you before i delete complete G1
Or is it enough to remount with that command above and then go with ASTRO FIlemanager to that directory and delete it?

Yes, you remount it that way (or with DroidSans) and rm the Amazon file. I would still recommend against deleting the messaging one though.
I tried it this way, but it says error "Read only file".
I think i just let it on the phone and try to ignore that app.

use this code to remove amazon
Code:
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
rm -r /system/app/com.amazon.mp3
that will remove amazon but removing messaging will make your system EXTREMELY unstable and most likely unusable
The problem was that i don't add the Fileending ".apk"
Thanx for ya help, tubaking182. It worked with your Command with adding .apk
Got the next problem, now i want to delete the Messenger App 'IM' but even if i do the same with 'amazon mp3' it says rm: cannot remove '/system/app/com.android.im.apk': No such file or directory
So what i am doing wrong, i tried it with "rm -r /system/app/com.android.im.apk"
"rm -r /system/app/com.android.im"
And many more but i get ever the same output -> No such file...
That means theres no such file...doesn't exist.
IT might be named IM.apk
Mh you're right!
I dont know how it tells me 'com.android.im' in ASTRO Filebrowser, and why i could delete it with IM.apk
With AmazonMP3 i have also to write: com.amazon.mp3.apk
Doesn't matter, THANK YOU for the fast help
amazon
spend a couple bucks and get root explorer, it is well worth it, and then its very easy to delete anything after that.
Wait wait let me get this right ... with root explorer i could avoid the whole going to terminal and typing all that code and just simply delete the apk from root explorer program and thats it >?
Can it really be that easy ... tell me thats the case
Also when you use the terminal code or the root explorer method ( if it can be done like that) when you go to applications in the phone menu to view list of apps you still see the amazon mp3 app in the system .. how do i remove that also

How to UNINSTALL unwanted stock/preinstalled apps from G1

How to remove unwanted stock/preinstalled apps
This is not a question. This is howto
I DID search through the forum and found nothing but
Q: how to remove/uninstall preinstalled apps ?
A: no way !!!
WHAT ??? WRONG ANSWER !!!
Here is how:
First of all I’ll describe my rooted, of course, phone configuration, so if you are on the same boat you can do same trick 99% if not you’ll know where to go
- CyanogenMod 4.1.2.1 (this is latest experimental as of sept-05-09) –works very stable for me
- 4GB SD card partitioned: FAT32, ext3 (512mb), linux_swap (32mb)
(great guide how to part your sd here: http://androidcommunity.com/forums/f56/compcache-userinit-22465/index4.html#post232988 (page 4)
- CompCache with Backing Swap (here: http://androidcommunity.com/forums/f56/compcache-userinit-22465/index4.html#post232988 (page 1)
Requirements:
1) G1 rooted phone
2) Explorer with ability to explore /system folders – I use Astro (market)
3) PC/MAC
4) SDK installed on it (http://developer.android.com/sdk/download.html?v=android-sdk-windows-1.5_r3.zip)
Steps:
1) first and very important: full backup of your system.
- DO NANDROID (it’s preinstalled in Cyano, search forum for “nandroid” if you don’t have it)
- DO ext3.tar (if you use ext3)
- Make full SD copy to your PC
As described here: (yes, same tread, thanks to bdb4269) http://androidcommunity.com/forums/f56/compcache-userinit-22465/index4.html (page 4)
Now we are safe..well, almost
2) find full name for the application you want to uninstall, say for Amazon MP3 it will be com.amazon.mp3.apk
I did it like this
- open Astro explorer
- go to the very top (/)
- search “amazon”
- when search done, write down full app name
- long press trackball – chose – open containing folder – remember the path (ie /system/app)
3) Assume SDK and USB drivers are installed ( http://developer.android.com/guide/developing/device.html )
And phone is connected to pc/mac
= below guide is from http://oneclickandroid.blogspot.com/ with my comments =
- Start emulator (don’t think it is necessary, but lets follow – emulator located in SDK folder\tools\emulator.exe in my case C:\SDK_15\tools\
CMD window pops up for a second and disappeared
- open CMD prompt (in Windows: Start > run > print: cmd , hit OK/enter)
- execute "adb shell" in on terminal from SDK_ROOT/tool folder
(if you did not register SDK folder in windows variables you need to cd to this folder first:
print: cd c:\sdk_15\tools hit enter
print: adb shell hit enter, you’ll see new prompt appeared: #
- print: mount -o remount,rw /dev/block/mtdblock3 /system
This will mount your system folder with read/write permission
- go to system/apps folder of your phone
(print: cd /system/apps hit enter)
*** guide says “/system/apps” but in my case it is “/system/app” ??? (remember I asked you to write down full path and name from Astro ? check your path first ***
- print: rm yourunwantedapplication.apk
i.e. rm com.amazon.mp3.apk hit enter
now, check installed apps in your phone (no reload req.) – is amazon disappeared ?
I wish to try this with app for that has a replacement from the market, like
Dialer – aTakePhone or Music – Meridian etc
Hope someone brave will do it before I do
Deleting may be unsafe if other preinstalled apps or process have links to uninstalled app
What happens in this case? wish someone knows the answer.
I dont think this trick will speedup your phone if you've moved your apps to ext2/3/4 already I just dont want to see useless apps in my phone/pc
Please reply here if you have experience of deleting preinstalled apps
sorry, english is my second languague
Good luck !
Hahahaha... all that trouble just to install a few unnecessary apps off of a ROOTED phone?! If you had searched, you'd have seen the numerous posts where we've posted instructions on uninstalling apps through Terminal. Literally 4 lines of code at most! Note that you can do this with any app you don't want. I have xROM, and one of the first things I do whenever I clean install to the latest version is replace ringtones and remove apps, including HTC Mail, Email, Amazon mp3, and Android Music. It takes me about 2 minutes to remove these apps.
Example for removing Amazon MP3:
su
mount -o rw,remount /system
rm -r /system/app/com.amazon-mp3.apk
mount -o rw,remount /data
rm -r /data/data/com.amazon.mp3
exit
exit

That's not how you start the emulator, in the window that disappears is a message telling you to start with the proper parameters, which you'd see if starting from a command line. If the emulator actually was running, then all your adb commands would then fail because it wouldn't know what device you wanted to address, you'd have to use "adb -d" to tell it to use the real device rather than the emulator.

Easy way to remove unwanted preinstalled apps
Use Root Explorer to browse to /data/app_s and find the applications you don't want. Delete the APK and ODEX files and you are done.
Always remember to make a backup of your phone, before you start deleting.

The app_s folder is only used for Hero ROMs because there isn't enough space in /system, so it's placed in /system/sd (the mount point of the ext partition) if you have an ext partition for A2SD.
For regular google source builds just go to /system/app.

Sorry to kind of hijack this but cyrket.com always shows as a blank page.
anyone know why or how to fix that?
i think simply deleting the apk files and data folder will keep an entry in some kind of registry in android. if i just delete the apk files and data folder and run fix_permissions, it shows the same number of processes.

is a rooted file browser and it is, by far, the easiest way of uninstalling any stock apps.
Click one button to make the system folder re-writable (same thing with data folder, just a button), navigate to the apps directory and just delete. or you can search for the app and just delete it from the search window. Voila!

Apks safe to uninstall on Liberated FR series ROM?

I need to uninstall as many apks as I can from my phones memory and download them off of market and install on my sd card to free up memory. My phone memory is pretty full and seems to be causing it to lag.... What are the safe ones and unsafe ones to remove?

If you can find the app in the market then its safe to remove. If its in the market that makes it optional. However removing google apps can have adverse affects on other google apps, but your phone will still continue to function just fine, and most if not all the google apps can be found in the market (with the exception of the market itself, dont remove that!). Apps such as the music app and clock apps can be replaced entirely by market apps. Preinstalled wallpapers can also be removed from the rom. Another thing i remove is any ringtones I dont think I"ll need. I dont know about liberated, but cm6 has WAY more ringtones than I need/want, so I just delete em. I also now remove the boot animation from the ROM before installing it to save a few MB. You just get a black screen where the bootanimation would normally show up until the phone boots.
Whats the easiest way to remove files? Ive tried to use Root Explorer and Titanium Backup but they show back up when I restart... Im hoping there is an easier way to remove than adb.....????

adb is pretty easy actually. Search the forums for making a cmd shortcut for adb, or if someone remembers how they could post it (this will make life infinitely easier). Then you just boot into recovery and plug in the phone, type the following without the apostrophes:
'adb shell' hit enter.
'cd /system/app' enter.
'ls' enter. (this will pop up a list of the apps you have)
'rm name of app.apk' and its gone forever.
Just keep repeating that last step for every app you want removed.
Can i do this via Terminal Emulator?
yes but the command is different...id give it if i knew it...

Im having a hell of a time removing apps from my Liberated Aria. I have installed ADB and the necessary software. I am able to get into CMD and get a listing of files (apk's), but they do not remove... what commands do I need to use?
Ive tried
rm /youtube.apk
rm /system/youtube.apk
rm /system/app/youtube.apk
They are still there... maybe Im not mounting the drive? Or its not in Read/Write mode?

make sure your bored into clockwork recovery. Then go to partitions and mount system. then just follow those same directions I posted above. To remove the app you would type:
rm youtube.apk
Exactly like that, with a space after rm and no /.

Some times I use SystemApp Remover.
Its pretty easy to work.

How to Install/Remove System Apps on Android [MUST HAVE ROOT]

########## IMPORTANT UPDATE ##########
There is an APP available that makes this much simpler
* No Console Commands Needed
* You still MUST HAVE ROOT
* It must be installed on internal memory to work correctly
* Be sure you know what a system app does before you remove it.
* If you remove a vital app you could mess up your system completely.
The APP is Called: "System APP Remover"
Here's a Link to Download it: http://www.megaupload.com/?d=ZFC2C1R7

Here are the console commands for installing/removing system apps in android console emulator, very easy ; )
You must have ROOT and console emulator, I found this very helpful, so I hope it helps others as well...
_____________________________________________________________________________________
Install App to System:
Place APK file in the root folder on your sd card.
Open terminal and enter these commands:
# su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# cat /sdcard/filename.apk > /system/app/filename.apk
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
# reboot
_____________________________________________________________________________________
Remove App from System (Be careful what you remove):
# mount -o remount,rw /system
# rm /system/app/Filename.apk
[Optional, to make read-only again]
# mount -o remount,r /system
[When Finished]
# reboot

I am trying to reinstall some files I uninstalled. I went to the following link on this site and found some apps that people said could be removed - http://forum.xda-developers.com/showthread.php?t=773142
however, my Act1 video player now quits whenever I receive an incoming text, so I need to reinstall some programs and see which one is causing the problem
I downloaded an app called Android Terminal Emulator by Jack Palevich. I tried a "reboot" command (without the #) but it said reboot operation not permitted. Is this the Emulator I need to reinstall files? Am I doing something wrong?
--------------
EDITED:
ok nevermind, i realized the "su" command gives superuser access needed for the reboot....going to try to install files now
yeah, to use any root commands "su" must be used first otherwise the shell will think your just some generic user with limited privileges and nothing will work.
It's very important to identify any apps you plan on removing before you attempt it to make sure it isn't needed by another process.
You got lucky, some apps once removed can cause the whole rom to fail, so be careful!
- CuriousAndroid
well i think i messed something up...is there a way to recover back to stock after using the sdx stock app remover? i removed the video player but tried reinstalling it...when i uninstalled it from sdx, i noticed my other video player (Act1) would quit whenever i'd get an incoming text
i have all the .apks backed up, but after attempting to reinstall the stock video player, it hangs in MyFiles...then i reset back to factory (no Act1), and it can't play my videos, i get the error "No applications can perform this action"
Is there a way to recovery back to stock with all applications installed and in tact? i have all the .apks, but this video player won't work, after following your instructions above
thanks
It will work. Check the following:
* All shell commands are CASE-sensitive, so if the app is called Vending.apk you can't type vending.apk
* for the command to work you must have the apk on the root of your SDcard, not in sub-directories.
* if you have a copy of the rom you installed you can unzip it on your PC and find the system app folder, which you can use to cross-refference with the system/app folder on your phone to see if your missing something else.
in terminal you can list system apps like this:
# su
# cd /system/app/
# ls | more
[that will allow you hit space bar to navigate through app list if it's longer than a page,press ESC when done to go back to prompt]
* If all else fails you can backup your settings to your sd card and re-install your rom (as a last resort)
-Good Luck

When I am doing the first part here of installing app to system I dont just simply do that first I can already have an app ready to go that I want to move to sd card right? I am just making sure I didnt have to do that simply first before I even start moving the apps. This site has be great and thanks for everybody help. Wish I would have known have this site way back when.
What is "yaffs2" standing for? I type "yaffs" instead of "yaffs2". What has this done to my system? Do I have to expect any "side-effects"?
When I call # ls | more to list the directories content, the apk is listed but it is not installed yet. Is there anything else i have to do?
yaffs is nand flash filesystem
yaffs2 is more elaborate updated version
yaff2 has greater support
so if your device isnt supported by yaffs1, it may not work.
it's best to follow the commands as they're written.
apps still appear as apks in system/apps folder after installation.
Haha thats funny!! I downloaded this app.. put it on my sdcard.. installed it and when i tried to open it it said " Shame on you for trying to pirate a 1.00 app "
If you have Applanet just go there and look for Systemapp Remover - it's a bit older version but seems to do the job.

Grab the contacts.apk from the rom you're running and push it back in. Btw titanium backup removes system/apps without terminal commands while allowing to to make a backup first in case u want. it back or for little hickups such as this.

I did everything right, and the apps that I removed disappeared from the app drawer. But, after I reboot my phone, they show up again.
What can I do?
In terminal type
ls system/app
Hit enter and see if said apps are in the list

i got a better method.
app is called app quarantine
it need root and is totally free
it can quaratine every app including rom apps and system apps
really that thing awesome. no manuall backup needed anymore and as long you dont brick the os you can easy try and error - but of course still be carefull and login and activate com.brain.logic.provider lol
Hi there i use root explorer and that is the easiest way i think to remove system apps on android phones [root required] you can download root explorer from the market or get it from 4shared just search for root explorer.apk install it and navigate to /system/apps/ and the app you wish to delete long press the app and delete make sure you mount as read/write instead of read only.
Hope this helps 

actually its not and actually you didnt read my post
i advertise this little peace of freeware because it really made my day (im not related in anyway to the developer)
the quarantine removes it but store it automatically in another directory
just multiselect and press one button DONE
no need to single delete something because you always should backup first
for example turns out on samsungs device EMAIl application is also related to exchange sync - huh i was happy to restore it
really take a look -
btw i hate the root explorer - for some taksts might be usefull but fileexpert is way better in that and its free as the quaratine app is too

Installing system app
Hi, i have the same problem. I tried Root Explorer, and the Shell Commands method (with Cat command), the files i copy are in there, with all the permissions and everything, but when i reboot, none of them are installed, and my "contacts" app is still broken. Can anyone help please?
Nevermind, found the problem. I needed the exact files for my Atrix 4G with the same android version.
