[Solved]Help to mount SDcard

Hi I built a little script to mount my SDcard @ startup of the phone and install some apps.
here it is:
Code:
sleep 2
busybox mount > /data/mount.txt
busybox ls /dev/block/vold >> /data/mount.txt
busybox mount -t vfat -o rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,shortname=mixed,utf8 /dev/block/vold/179:1 /sdcard >> /data/mount.txt
busybox mount >> /data/mount.txt
sleep 3
echo "APPS installation"
if [ -e /sdcard/Apps-install/install.txt ];
then
echo "found file" > /sdcard/Apps-install/install.txt
cd /sdcard/Apps-install
ls *.apk > ./apps.txt
for line in $(cat apps.txt); do install -c -D /sdcard/Apps-install/"$line" /data/app >> /sdcard/Apps-install/install.txt; done
echo "ok" >> /sdcard/Apps-install/install.txt
else
echo "file not found" > /sdcard/Apps-install/install.txt
fi;
sleep 2
echo "Finish"
if [ -e /data/firstboot.sh ];
then
busybox rm -f /data/firstboot.sh;
busybox rm -f /sdcard/Apps-install/apps.txt;
fi;
echo "Restart"
sleep 1
reboot
I'm sure that the code is well executed (as is have data in /data/mount.txt) but the mount of the SD and so every work related to the SD
What is strange is that script work if i execute it after the phone has completely started.
Can someone help please.

Ok finally found bye myself.
I changed the device: /dev/block/vold/179:1 for /dev/block/mmcblk0p1
That's all.

What replaces stagefright?

I found a script that adds boot audio. In it there is a line calling stagefright, stagefright either doesn't exist on my ROM and I have no clue as to add it. Here is the script in question which I don't know the original author however lithid from http://forum.cyanogenmod.org did some work on it and was close to creating a updater-script. Please Help Me as I know some scripting but not a lot
PS I was advised to ask this question to the devs by a cyanogenmod.org mod named bassmadrigal

Not sure if this works , but I will eventually try it , but not now , on my free time.
stagefright indeed is not included , my phone too doesn't have stagefright , if you go to youtube and search for android developement tutorials by "thenewboston" . you'll find 200 videos series , just watch the first 20 ones and you'll learn to use Media which replaces stagefright...I didn't try it yet.
It includes
Our_Player and Media Player and the directory of the song....check it out and give us heads ups!

I appreciate the info, I took a look at his tutorials esp the ones involving animation, he really knows his stuff. I am not a Java programmer by any means and to be honest I find it quite tedious, it's like trying to teach a baby (this case the Dalvik VM) to do basic stuff like draw a green ball took like 20 lines of code!
What I need to know essentially is, do I have to use JAVA to get this to work now? In the past ie ICS and lower, there wasn't a problem with Custom Boot Audio, now with JB it seems it has disappeared from the radar.
I know the binary /system/bin/bootanimation (is this written in JAVA?, is there a source code for this bin?) is called at boot time by init.rc in the following manner:
Code:
service bootanim /system/bin/bootanimation
class main
user graphics
group graphics
disabled
oneshot
/system/bin/bootanimation (at least from what I gather) looks in /system/media for bootanimation.zip (zipped in store mode) decompresses it , looks at desc.txt for the code and displays the animation png by png.
In some desc.txt there is an s line, example:
Code:
# mobility
p 1 0 SOUND
s transdroid.mp3
which is SUPPOSED TO call a custom boot audio from /system/media (.mp3?) at the same time. This appears not to work. So logicaly I think the binary needs some tweaking. Can you offer any suggestions?
As you can see I have spent ALLOT of time mulling over why this,one would think, simple task: display a series of images and play audio at boot time I mean how hard can that be?
I am not trying to be a pest I just need to know WHY this doesn't work in JB (CM10.1)

[Q] Odex Script For User (/data/app) Apps :)

Dear bros and members here,
I want some script for using dexopt-wrapper to some location
Example: if there is file in (/sdcard/app)
then the script should prompt two request:
the first is the apk file name
and the other is the odex file name and should execute
dexopt-wrapper /sdcard/app/name.of.the.apk /sdcard/app/name.of.the.odex
Please, I want this in shell script

Here you are:
Code:
#!/system/bin/sh
# In the name of Allah
tmp=/data/local/tmp
mkdir $tmp > /dev/null 2>&1
BCP="`cat /init.rc | grep BOOTCLASSPATH`"
echo $BCP>$tmp/fbcp.txt
sed -e 's/export BOOTCLASSPATH //g' $tmp/fbcp.txt>$tmp/bcp.txt
BCP="`cat $tmp/bcp.txt`"
rm $tmp/fbcp.txt
rm $tmp/bcp.txt
echo "Please enter the name of app to odex:"
echo "Example: Browser"
echo "--->"
read APP
if [ ! -f /sdcard/app/${APP}.apk ]; then
echo "Requested app not found."
echo "Please check the app name again."
else
dexopt-wrapper /sdcard/app/${APP}.apk /sdcard/app/${APP}.odex ${BCP}
zip -d /sdcard/app/${APP}.apk classes.dex
echo "Done!"
fi;

Thanks a lot bro!

There's a syntax error.
I type in the terminal and output is looked like this
/sdcard/odex.sh: 4: Syntax error: Bad fd number
anyway, I fix it to
line 4: mkdir $tmp > /dev/null 2&>1
but it still doesn't work..
Many errors in shell script.. Please test it and correct something.. Please bro..
I really like your script if it would be executable because it has classes.dex delete function..
Thanks

What's the fastest ROM to date?

Finally got a new battery after over a year of not using my Droid 4.
Flashed latest CM13 nightly, 1.4ghz OC. Everything seems slow.
My 512mb ram single core $19 cheapo runs smoother.
Anything I do has a half-second or so delay, clean install with nothing running in the background.
Ideally I would just go back to some minimal 2.3.7 ROM, but compatiblity for new programs is getting iffy.
So, as of 2016, what has the smoothest ROM to do date been?

I'm running very, very debloated, overclocked stock JB 4.1.2 with Greenify and ram manager and it works pretty well. Even most of new games and emulators rund good.

Cyanogenmod 11 is quite good. One thing I noticed is that the virtual ROM slots are extremely slow, due to the loopback devices.
One way to go is to install the ROM to the virtual ROM slots to test if they are working correctly and then install it into stock slot for real use.

Up, same question here

I use cm11 or cm12 (i find cm13 extremely slow) But with the following tweaks made from my daily experience feel free to try it

Thank you man, this script made my droid 4 a whole lot more responsive and it does not reboot every few hours anymore.
Quite a few commands in that script don't work, probably due to different paths (sio plus as io scheduler and stock rom boot slot), but those that work, really seem to help a lot.
Oh and you should update the comment in that script about the zram size.

Was testing on different Kernels that's why the paths are wrong.. Please replace the sio plus with cfq or bfq (i forgot to change that)
I am glad that those tweaks help you

What about this one? Mentor's ROM http://forum.xda-developers.com/showthread.php?t=2122709
That's what I found on my used Droid 4... should I give it a try?

why replace sio plus? I used bfq before, but when i googled for sio plus i only found people saying that sio plus was the best of them all.

If your kernel support sio plus, of course use it.. else cfq or bfq is a good alternative

What am I supposed to do with these lines? And can somebody please explain what they are doing specifically?
I was trying to find a way to enable zram to cope with the small amount of memory. swap ram is an alternative, but i heard zram is faster and not stressing the storage like swap ram would.

/system/su.d

Hello. I found same questions in other topics, but couldn't find answer.
I would like run script from /system/su.d folder:
Code:
#!/system/bin/sh
echo 0 > /sys/fs/selinux/enforce
or
Code:
#!/system/bin/sh
setenforce 0
and I even tried to run test script:
Code:
#!/system/bin/sh
touch /data/local/tmp/test.txt
echo "test" >> /data/local/tmp/test.txt
But no one of them works. I tried different names for files, gave different chmod (644,700,755). Nothing helps me to run script.
Mb somebody can give me advice what's problem can be?

The file is called 00mountsd and is used to give access to exfat microsd on stock android 5.1 running on a Chuwi Hi10pro tablet with cherry trail z8350 cpu. I used this on a previous version of the tablet and it worked fine although that tablet came with RemixOS.
The file runs without errors when run manually and succeeds at it task
ls -lZ returns this -rwxr-xr-x root root u: object_r:system_file:s0 00mountsd
I'm running SuperSU Free v2.79 everything else works fine.
Any ideas?
