How do you copy something from the SDcard to the Phone Memory?

[Jaylor]

I need to copy an app stock app that I deleted (Yes, I know I shouldn't have.. now!) because I need to exchange my phone.

I have root access and was thinking that

mv /sdcard/<file> /system/app/<file> would work but I get

a failed message that says - Cross device link.

You have to mount the home first under super user.
In a terminal:

su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
Then type your command
mv /sdcard/file /system/app/file

In adb:

adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
mv /sdcard/file /system/app/file
sync

And you're done! (These should work however I'm a unix newb)

I've tried that (And just did it again to make sure)

still gives me the cross-device link error.

I'm guessing I actually have to mount the SD card but I'm not sure how.

I've just typed 'mount' to see what is there and I see the sd card but have no clue how to mount it .. yet anyway

I'm playing with it now but I figured I'd check to see if anyone else has already done it.

EDIT

And I haven't installed ADB yet.

just use cp instead of mv and it should work fine

[Jaylor]

I tried that one also,

There is no cp command, I just get a cp: not found

I also checked in the /system/bin folder for a cp command and its not there at all.

[vwpanda]

install busybox or use Better Terminal Emulator and cp will work
you should have cat though. so:
cat /sdcard/file.apk > /system/app/file.apk

good job. thats a great point.

[Jaylor]

Sweet! Better Terminal did the trick!

Thanks vwpanda!!

To bad best buy is now closed and I can't exchange the phone tonight.. ahh well.

I'm just happy my hair is really short or I would have bee ripping it out trying to figure out how to fix this.

Oh, and the best part cping the app back over survived a factory reset so they won't be able to figure out I rooted my phone when I return it.

^^This worked for me through adb. Just stumbled across this thread while trying to figure out how to do it. Thanks!
