Why is it that I cannot copy a file from my sdcard to /sys and its subfolders?
I have change permissions for every directory to 0777 and I remounted the file system using
mount -o remount,rw /dev/block/mtdblock3 /
What am I missing?

/sys is a virtual directory built/populated by the kernel. You can only write to existing files in it (and only selected ones).
You probably want to work on /system but then your command is wrong on the mount point which must be /system, not /.
I am not sure the block device is the right one, I can't check my Dream right now.

After a sleepy ODIN flash, using SPICA ops with G3 firmware => STUPID??? NO, not done yet , next ODIN flash segment, accidentally stick clear phone EFS via Debug options (DOUBLE CRAZY!!!) NOW i lost the precious IMEI and /efs partitions corrupted as well.
i've got the fixed nv_data.bin and both stl4.img and bml4.img from [email protected] (attached). Thanks for his kindness and supportive to the community!
But even with those i still can't fix the issue!!!! /efs did not mounted via mount command...
as in a GOOD G3, mount command result will be as below:
Code:
rootfs / rootfs rw 0 0
tmpfs /dev tmpfs rw,mode=755 0 0
devpts /dev/pts devpts rw,mode=600 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
tmpfs /sqlite_stmt_journals tmpfs rw,size=4096k 0 0
/dev/block/stl6 /system rfs rw,vfat,llw,check=no,gid/uid/rwx,iocharset=cp437 0 0
/dev/block/stl7 /data rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,iocharset=cp437 0 0
/dev/block/stl8 /cache rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,iocharset=cp437 0 0
[B]/dev/block/stl4 /efs rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,iocharset=cp437 0 0[/B]
/dev/block//vold/179:1 /sdcard vfat rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=1015,f mask=0702,dmask=0602,allow_utime=0020,codepage=cp4 37,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
in my case the bold line just missing... so this is must be the problem.
I tried to do the same as SPICA's method as below:
Code:
$su
#dd if=/sdcard/bml4.img of=/dev/block/bml4
#reboot
It's OK then but...
Code:
$su
#dd if=/sdcard/stl4.img of=/dev/block/stl4
/dev/block/stl4: cannot open for write: Invalid agrument
With this error my /efs cannot be mount... and still missing from the mount command. I'm just a linux noob so pls help me out. How can i restore the stl4 partition properly???
My girlfriend now really mad at me due to she don't have her beloved phone this christmas already. OMG!!!!!
and to all rooted i580x user Pls kindly help compare your "good" /efs folder... maybe mine missing something???? due to one time Erase Phone EFS using Odin Debug Options.
Mine /efs now as below:
Code:
/efs/nv_data.bin
/efs/imei/.nvmac.info
/efs/.files/.dm33 (empty folder)
/efs/.files/.dx1 (empty folder)
/efs/.files/.mp301 (empty folder)
And if you can do adb shell, it'll be very kind of you by sharing your good backup stl4 and bml4 - for research purpose (those partitions did not content any of yours personal data - so PLS HELP!!!). Pls do the backup partions as below and share your img here if possible.
Code:
$su
#cat /dev/block/stl4 > /sdcard/efs_dev-block-stl4.img
#cat /dev/block/bml4 > /sdcard/efs_dev-block-bml4.img
TIA and Best Regards
P/S: when do the ls /dev/block/stl* the stl4 is there but cannot restore using the backup img. it's weird...
Code:
#ls /dev/block/stl*
/dev/block/stl1
/dev/block/stl10
/dev/block/stl2
/dev/block/stl3
/dev/block/stl4
/dev/block/stl5
/dev/block/stl6
/dev/block/stl7
/dev/block/stl8
/dev/block/stl9
same for bml4...
I suggest you remove the images.zip
This contains your IMEI, so anyone can clone it.

Hi, my phone is a samsung galaxy y PRO. Android 2.3.6 rooted
I am trying to disable the keypad backlights...
In here:
\sys\class\backlight\keypad-led\brightness
when i set it to 0, the lights turn off, and after that i change the file permissons to 444 with chmod.
But when i turn off screen and turn on again (stand by mode) the keypad lights turn on again, and when i go to edit the brightness file again, it shows the value 255.
Any solutions?? Also when i try to remove the file (via terminal with SU) i get a operation not permitted message.
Help please.
Thanks!
BTW, i will donate do the guy that makes it work!
Dumb question, is /system set as r/w?
Sent from my LG-P999 using xda premium
Yes, i tryied with total comander, setting system to r/w
Well, then the alternative is copy it via cwm and set the permissions in the script. I can't do it right now, I about to start work, but if no one has handled this by the time I am off and home, about 9:00pm CA time, I will get it set up.

Please do that! I will get in here asap. Cya in a few hours.
Thank you for trying to help!
BTW, i tryed to install ClockworkMod via Rom Manager but it says that there is no support with my samsung galaxy y Pro (GT-B5510)...
Ok, i got a temporary ClockworkMod that i can use when needed...
Ok, did some researching of my own for your phone, check your pm.
Ok, this is sort of simple, the file is called "brightness" and its content must be a zero "0". Thats it. The file must be placed in "/sys/class/backlight/keypad-led/".
I don't know how the script you need should look like, but commands to change the file to disable keypad light should be:
echo 0 > /sys/class/backlight/keypad-led/brightness
And the permission command:
chmod 444 /sys/class/backlight/keypad-led/brightness
I know the basic of how it should look and what is needed for it to work, I have a zip I made for myself for copying over ringtones and notifications from a flashable zip. I need to have what partition it's on and (since I guess it's /sys and not /system) be able to mount /sys so Tue file can be copied. The ROM I found it's for your phone. There seems to be very limited data on your phone. Like I said, I have the zip mostly set up, I just need to make sure my mount command will work and for that I need more info. I think I have it but I can't verify that I do.

How can i help? I have sent you some info about partition on private msg...
Here is the file... It is zipped, just extract it...
About the partition, Mount command shows: "sysfs /sys sysfs rw, relatime 0 0 "
BTW, i have been checking and the correct path to the file is: "/sys/devices/platform/keypad-led.0/backlight/keypad-led"
The other path i told you before was a link to this one... Sorry...
Complete result of mount command:
$ mount
rootfs / rootfs rw,relatime 0 0
tmpfs /dev tmpfs rw,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0

Can you do something with this? I hope so...
hmm, we may have to change our strategy, maybe not. I need to see about a couple of things before I have you try anything.
On an interesting note, I noticed that for /sys the values after realtime are 0 0, I'm mostly familiar with PC's and learn as I go on Android, but if that means what I think it means, that partition can't be modified at all while the system is booted.
On my phone that directory is mounted, but there are no files that I am able to view either via Droid Explorer or Root Explorer.
Do you know anyone else that could join us on this adventure? do you have anything else in mind? I am able to set the file to 0, but there are some events that set it back again to a certain value, like screen off and on, etc...
I dunno why or how, but i set it to 0, i apply chmod 444 but it still changes the file to a certain value...
News?
Yes.
Place the attached script in: /system/etc/init.d/
reboot and you should be good. Found the info here:
http://forum.xda-developers.com/showthread.php?t=1488492&page=4
Some say it works, some say it doesn't.
edit: file attached, just take it out of the zip file.
I don't have the folder /init.d/ in the /system/etc/ folder :|
This means i don't have init.d support...
Ok, i found a way to run it during boot time:
How to run the scripts during the boot using SManager:
Steps to run the scripts during the boot:
1. Test the scripts out completely before start to run on boot.
2. From the SManager tool, select su and boot icon. Exit the application and reboot the phone.
3. If you did not change the SManger config, then you will see the SManager log after the boot. Check if everything is fine. If the scripts run OK many times without any issue, then you can uncheck the option showing SManager log after the boot.
And during boot it writes 0 to the file and it changes its permissions to 444. But even without the permission to write on the file, the system is able to change the value in the file!
Please help me,
First of all my infinix x551 16gb 2gb ram is running on kitkat, then i have successly upgrade to lolipop via flashtool. (my infinix ealry product is only support kitkat)
after while i realized my phone is slower with lolipop then i tried to downgrade to kitkat using stok rom and flashtool.
But my phone is now bootloop (after infinix logo then black screen)
tried to enter rec mode and it load rua1 autoCWM v5.5.0.4 but there is error e:cant mount /cache......
i have tried MTK Droid tools but i dont understand how to flash with it.
i have tried adb shell command :
~ # mount
rootfs on / type rootfs (rw)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,mode=755)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
/dev/block/mmcblk0p5 on /system type ext4 (ro,relatime,data=ordered)

for information i tried install any stok rom i can find for my infinix with flashtool (download only or format and download) it is succed (after flashing) but it still blackscreen when i tried to boot.
I though the problem is from my stok rom that i tried to downgrade that corrupt my partition table.
i check with adb shell i found ext2fs is exist but ext4fs is not and my cwm is read only on ext4fs so there is mistmacth boot partition format. however i dont know how to change the partition and clean install my infinix.
any suggest are welcom...
i need help as fast as posible.
Thank you for any of you that help me.
any help its welcome....
or did i post in wrong section.......
anyway, i tried enter fastboot with adb fastboot,
