[Q] s5570i - virtual sdcard - General Questions and Answers

hi friends
on my s5570i, cause the sdcard reader is broken, i have created a virtual sdcard with this step:
1) dd if=/dev/zero of=/data/storage.img bs=1024 count=13000
2) mkfs.vfat /data/storage.img
3) losetup /dev/block/loop0 /data/storage.img
4) ln -s /dev/block/loop0 /dev/block/vold/179:1
5) mount -t vfat -rw -o dirsync,nosuid,nodev,noexec,relatime,fmask=0702,,uid=1000,gid=1015,dmask=0702,allow_utime=0000,utf8 /dev/block/vold/179:1 /mnt/sdcard
and now i see my virtual sdcard with "mount" command so:
/dev/block/vold/179:1 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-
1,shortname=mixed,utf8,errors=remount-ro
( is this correct? )
now...i can use it, copy file ecc, shot photo but only with ICS camera, and use normally with Root Browser Lite.
My question is.. why like Myfiles.apk or stock Camera.apk don't see the virtual sdcard as a real sdcard ?
What should I do to make it recognize at other app as for example Camera.apk or Myfiles.apk ?
I hope someone can help me
thanks friend

please help me move my apps to sd card

i know theres a thread but i'm confuse about what to install and run to transfer my apps to my sd card.
my sd card is already partitioned to 6gb fat32 and 2gb ext2 and its rooted with jf1.41 as well.
please give me a specific instructions cuz im a noob when it comes to adb shell sdk cmd or whatever computer words.
thanks in advance!
Well i'm a noob as well can't seam to finish the last step myself but i'll try my best.
Just a wild gues u r running Windows right?
yeah im using windows xp but it has vista transformation pack if that will make a difference.
Ok.
Have u got "modified mountd & init.zip (685 Bytes, 475 views)" wich is an attachement at the bottom of http://forum.xda-developers.com/showthread.php?t=468959 ???
Download this small zip from http://modmygphone.com/wiki/index.php/Setting_up_ADB . Unzip the files to a desktop and copy it to system folder after that follow this link http://www.computerhope.com/issues/ch000549.htm.
let me know when u r done???
But remember i am also a big time noob but just trying to help as much as i can when no one else will so if i get some thing wrong don't get angry with me just let me know what i told u that was wrong and that way we can help each other out and correct one n other.

if you copy the modified mount.conf and init.rc files to the SD card at the root then this would be the way in "Terminal":
$su
#busybox cp -a /sdcard/mount.conf /system/etc/mount.conf
#busybox cp -a /sdcard/init.rc /system/init.rc
#mkdir /system/sd
now that the modified files are there you MUST reboot .. this is all done after you have root and after you have done the double partitions on your SD card .. once you reboot you should go back to the "Terminal" to make sure everything's good
$su
#busybox df -h
if you don't see a line like this:
/dev/mmcblk0p2 1.5G 94.4M 1.3G 7% /system/sd
then something didn't mount properly .. so if you DO see this line now you can continue:
#busybox cp -a /data/app /system/sd
#rm -r /data/app
#ln -s /system/sd/app /data/app
#busybox cp -a /data/app-private /system/sd
#rm -r /data/app-private
#ln -s /system/sd/app-private /data/app-private
now the apps are all on the EXT2 partition of the MicroSD .. happy downloading
I don't know what i have done wrong but eveything i try i keep getting errors and u have been more then help full but i am proberly to stupid to do it my self and i know i can do it if only i could find a video toturial from youtube or so but can't find any so i am stuck here.

it's a nice thought .. not really sure i'd want to hold that kind of responsibility tho .. i think it'd be like calling me "Mr. President" when i drive the local garbage truck .. these guys are doing great here .. i'm just glad to lend a hand and hope it helps out
Hey guys just thought i'd chime in.
Firstly just to clarify are you using adb from your windows system or are you trying to do this all on the terminal app because these commands are issued to terminal after replacing both mount.conf and init.rc as described above
$su
#busybox df -h
as above you should see a line "/dev/SOMETHING" "size data" "/system/sd"
if you don't see this line then there's most likely a problem with your card format, did you make sure you had fat32 first then ext2 in that order on the card, fat32 must be first. i find it helps to check if camera can use the sdcard, if it can't, reformat, unmount and check camera again.
Assuming you've gotten this right so far
#busybox cp -a /data/app /system/sd
#rm -r /data/app
#ln -s /system/sd/app /data/app
#busybox cp -a /data/app-private /system/sd
#rm -r /data/app-private
#ln -s /system/sd/app-private /data/app-private
and hopefully your apps should all work, but not appear as downloaded in the market (don't worry this'll change if you reinstall them from the market)
if you're using adb from windows to try the above the commands will be slightly different:
Procedure:
***********************************************************
- this can be skipped if you've already replaced the mountd.conf and init.rc
adb remount
adb shell mkdir /system/sd
adb shell ls /system
adb push LOCATION OF FILE/mountd.conf system/etc/mountd.conf
adb push LOCATION OF FILE/init.rc system/init.rc
(LOCATION OF FILE = the folder you have the modified files)
adb shell
reboot
***********************************************************
If you've skipped ahead
adb remount
adb shell
busybox df -h
as above you should see a line "/dev/SOMETHING" "size data" "/system/sd"
Again if this line doesn't exist you've missed something, go back
busybox cp -a /data/app/ /system/sd
rm -r /data/app/
ln -s /system/sd/app /data/app
busybox cp -a /data/app-private /system/sd/app-private
rm -r /data/app-private
ln -s /system/sd/app-private /data/app-private
reboot
and hopefully your apps will all work and again, not appear in market.
If this doesn't help please advise what error messages you are getting and exactly where everythings going wrong, maybe we can get you back on track.
just reformated the card from fat 16 to fat 32 as u said hope it works now lol.
And thanks for the help.
Keep u posted.

The list goes on and on. puha need a smoke.
But thanks for help.
why does it say "No space left on device"???

untd.conf': No space left on device
Ok might be fine but better safe than sorry your last line says:
/dev/block/mmcblk0p1 1.3G 4.0K 1.3G 0% /sdcard
That means that you're sdcard in fat32 format is only 1.3gbs in size is that correct? I assume this means you're using the sdcard that came free with the phone (2gb) if your card is larger say an 4 or an 8 something has gone wrong, but if this is correct lets move on.
cool so your sdcard is now partitioned fat32 -1.3gb followed by 0.7gb ext2
better safe than sorry redownload http://forum.xda-developers.com/attachment.php?attachmentid=139735&d=1230107855 the files and place them (the 2 files, not the folder) in the same folder as adb (do not mount your usb card)
>adb remount
>adb push mountd.conf system/etc/mountd.conf
>adb push init.rc system/init.rc
>adb shell
#mkdir /system/sd
#ls /system
(make sure a folder called sd exist)
#reboot
When your android reboots
>adb remount
>adb shell
#busybox df -h
Cross fingers, pray, beg, bargain and look for the line
"/dev/SOMETHING" "size data" "/system/sd"
in case this doesn't work i'm going to pm you my email, we can chat on google messenger and try and get this sorted
Quick question are you remembering to "adb remount" when you attach the phone - if you don't the phone wont be writable, which may explain the no space issue here:
C:\Users\Illuminator\Desktop\G2>adb push C:\Users\Illuminator\Desktop\G2\/mountd
.conf /system/etc/mountd.conf
failed to copy 'C:\Users\Illuminator\Desktop\G2\/mountd.conf' to '/system/etc/mo
untd.conf': No space left on device
*********but here you are trying to write to a location that doesn't exist, unless you see the magic line ending system/sd you cannot proceed
# busybox cp -a /data/app/ /system/sd
busybox cp -a /data/app/ /system/sd
cp: write error: No space left on device
cp: write error: No space left on device
Jesus this is killing me!!! yesterday i got all the way to step.12
And yes the sd came with the phone sdcard in fat32 -1.3gb followed by 0.7gb ext2 - yes that's correct.
And in case u where woundering then yes my phone is rooted wich was a pice of pie compered to this lol.

You're not kidding i've done this 5 times (on 3 phones - updates) never had this much trouble!
do you have the same problems if you sit the files on your sdcard and do the following? if so as much as it sucks to lose your data i would strongly suggest doing a wipe before hand (reboot phone holding home and at prompt alt + w)
>adb shell
#busybox cp -a /sdcard/mount.conf /system/etc/mount.conf
#busybox cp -a /sdcard/init.rc /system/init.rc
#mkdir /system/sd
C:\Users\Illuminator\Desktop>adb shell mkdir /system/sd
mkdir failed for /system/sd, File exists
fantastic, well that's something! how about the other two did both copy successfully? and if so does the magic line appear after reboot?

wow that's not right your apps should not be there:S

Ok thanks i am ready in chat mode hehe.

Swap SD on CM 11 ?

file partioning MTD has changed in CM 11 4.4.. lets wait for our great developers to find out a proper way for swapping memory.
Use script manager to execute this script at boot..
For GalaxySL = i9003
#!/system/bin/sh
umount /mnt/media_rw/sdcard0
umount /mnt/media_rw/sdcard1
mount -t vfat -o uid=1023,gid=1023 /dev/block/vold/179:49 /mnt/media_rw/sdcard0
mount -t vfat -o uid=1023,gid=1023 /dev/block/vold/179:1 /mnt/media_rw/sdcard1
Can't be installed inside "init.d" folder.. Suggest to use /data..
Replace the id = 179:49 and 179.1 according to your device internal and external id.You can check them by executing the command:
mount | grep sdcard0
and
mount | grep sdcard1
to swap change the id.. change the sdcard0 id to sdcard1..
I am currently trying this http://forum.xda-developers.com/showpost.php?p=48876834&postcount=472
so far so good but havent tested it much, i think games run slower..

mount command problem

I want to mount a file as file system in android.
so far I've done
create 1 MB file:
Code:
dd if=/dev/zero of=/sdcard/my_fs bs=1024 count=1024
format the file as vfat
Code:
losetup /dev/block/loop0 /sdcard/my_fs
mkfs.vfat -v /dev/block/loop0
mount it:
Code:
mount -rw -t vfat /dev/block/loop0 /sdcard/mountpt
but the filesystem is mounted as read only not rw.
when I excute the above commands from adb shell instead of android terminal emulator, it works fine and is mounted as rw.
whats wrong with the mount command? how to mount it as rw?
please help me!
ls -l output is
Code:
drwxr-xr-x root root 1970-01-01 05:30 mountpt

cw11 failing to swap internal / external memory

Guys, I'm completely lost in tutorials so pls help me I'm freaking out!
I'm trying to bring to life my mother's HTC Explorer so I installed CM11 (cm-11-20140316-UNOFFICIAL-pico.zip) using some yt tutorial .
It works fine and now I'm trying to increase the phone internal memory. But in vain :'(
I tried:
1) editing build.prop
Code:
persist.sys.vold.switchexternal=1
ro.vold.switchablepair=/storage/sdcard0,/storage/sdcard1
-> no change
2) Trying to execute the StorageSwap.sh
Code:
#!/system/bin/sh
umount /mnt/media_rw/sdcard0
umount /mnt/media_rw/sdcard1
mount -t vfat -o uid=1023,gid=1023 /dev/block/vold/179:97 /mnt/media_rw/sdcard0
mount -t vfat -o uid=1023,gid=1023 /dev/block/vold/179:8 /mnt/media_rw/sdcard1
-> not working! permission denied
Can someone pls share a proved and easy way to make this work??
