[MOD]Best RAM Optimizer!!!!

I haven't seen this being used by any dev's(as of yet anyways) and I've been running it for about a week now and its been great!!! Don't feel that it should be kept secret so just click on link and download script!! http://forum.xda-developers.com/showthread.php?t=1111145
Its pretty basic, here are the instructions from the link:
1) Download attached file (Juwe_Update-19092011_RAM_Script.zip) unzip S97ramscript and put it to /system/etc/init.d with Root Explorer (if you don't have init.d folder, so create new folder and name it to init.d) and set perms of S97ramscript to 777 (rwxrwxrwx)
2) If you have in your init.d folder other script for RAM management (for example Darky's rambooster), so delete it
3) Reboot your phone

have you done it to yours?any noticeable difference ?

Yippers, as mentioned in OP, been running for about a week and its been great man, highly recommend it! Let me know if you need any help! Just need basic knowledge of Root Explorer...

for any Root Explorer noobies who try this: to set perms to 777, just long press the script and wait for the menu to pop up. hit permissions and check everything
its in the linked thread, just thought it would save some digging for those who need the info

i know this is a super noob Q but how can i tell if its working? first time ive ever used a script

not very noob at all. hopefully you are aware of your overall performance in terms of battery life, smoothness, speed prior to running the script. let it run for a day or two and see if there are any differences. of course, with the dual core exynos it might be hard to see any differences in anything besides battery life because its already buttery smooth, but you get the point.

You know, you could simply use Autostarts and prevent most of installed apps from loading automatically on reboot. Not only will you get about 500megs of free ram on boot, the devices will boot faster and smoother.
I think I prefer that method over using dodgy settings which may not be optimized for this particular rom and 1GB of ram that we have.

Accidentally deleted stock Task Manager!!

So i just installed the new BM 5.0 and i was deleting unwanted apps via Titanium Backup pro .. i was doing it so fast that i accidentally deleted task manager! now everytime i click on the widget "Active Application" it fore closes! i tried to look for the stock task manager in the app store but could not find it! is there a way to undo the delete without doing a nandroid restore?

Use the feature in Titanium that can pull apks from cwm backups. You should be able to fix it with that.

1) Open TB
2) Go to Backup/Restore
3) Option soft key
4) More
5) Extract from Nandroid backup
6) Pick Task Manager
I personally tried it once and it didn't work for me, worst comes to worst I'll upload you the JobManager.apk (I assume that's the one you're talking about? The Samsung task manager?). But I assume it works, otherwise they wouldn't include the feature.

To install it, you'll need a file explorer with root access (ES File Explorer, ROOT File Explorer, etc.). Then you'll have to move it to /system/app (to get to /system you'll have to go one level up from /sdcard to get to the root folder /). Make the permissions read "rw- r-- r--" (how you do that depends on what file explorer you use) and then reboot. Should fix the issue.

It'll be an option in root explorer along the lines of "root access". I don't know the exact process because I use ES. Play around in the settings of root explorer until you find it. By default it's disabled to prevent users from actually screwing with their system operating system without knowing what they're doing.

did not find anything under settings but there was a button that said Mount R/O or Mount R/W ... so i selected the file to move then i went to system/app thrn i clicked the mount button on the top and it worked! Thank u so much for ur help and fast responds! u really saved mr from alot of grief.

Yeah it's the same thing, you're just allowing the system position to be written to. No problem. Is your task manager working as usual now?

Was it working fine when you first installed it? Either way, there's always 5 generic steps you should always take first when trying to resolve an issue:
1) clear application data
2) reboot to recovery and clear cache
3) clear dalvik cache
4) fix permissions
5) reboot
See if that fixes your issues

Bad flash do it again... I had the same issue updated everything and nothing helped til I rebooted wiped and reflashed rom.
Or try to install superuser and see what happens

I was reading somewhere that if you restore a backup the permissions or something get screwy and the only known fix is to re-flash the rom. it sucks

If anything I'm downloading Aokp again just in case.

Had the same issue. I had to reflash. This occured after a Nandroid backup for me.

Have to re-flash, I had the same issue, I did not realize I was on a Nandroid backup. Just do a fresh re-flash and you should be good to go. All of my probs with this are posted in the themes area, they are in the Android pissing on Apple boot animation thread =)

Hello,
I rooted my X10 mini and still can't delete stock apps from the system folder. The root explorer shows R/W but when I try to delete a .apk it says "Delete failed".
I'm not very confortable with flash or re-flash (stock ROM). Can you help me?

I had the same problem, I fixed it by going from CWM 5.x.x to CWM 6.x.x

Try using Titanium Backup.

Remember, you can't delete a file that is IN USE, ie; system files. You need to freeze/disable them first THEN delete them! Watch what you delete though, some files are needed, some files that you least suspect, and will cause problems if you delete them.

I'm experiencing something similar.
I have root on stock os but recovered from nandroid.
I can create folders, files, rename, edit text etc on some directories, yet I am unable for others.
I am trying to undrestand if this is because of
1) Nandroid backup
2) files are in use and I cannot edit or create folders in those directories?
I am trying to create folders and edit files in the /sys directory.

Are you using the 'Root Explorer' app to do this? If not, I suggest you get that from the Play store first. Secondly, make sure the "root privileges" are enabled in Superuser for the app.
If you have already done what I mentioned and still occur problems, may I ask what folders in the 'sys directory' you are trying to change? As majority of the files/folders you are seeing in that folder are there for a reason and named accordingly for your phone to utilize that directory and keep the phone working.

I am using root explorer app.
I have root privileges as well. The phone is rooted and permission is granted to RE
i was trying to change or create a new folder for the CPU states because my cpu spy wasn't reading any cpu states (which is another problem im facing).
1) With root privileges am I suppose to be able to create folders in any directory? I seem to be able to create/rename/edit files only in some directories. I seem to have the option to mount as r/o and r/w only on certain folders. The other folders defaulted to mount as r/w. I've also changed permission on the folders as well.
2) Why can't my BBS and CPU Spy read my cpu states, but can only read it when i enter in with my SetCPU app?

Unless you know the exact name and which sub-directory to place the folders to link with the apps you have mentioned, I suggest you do not add or modify anything.
The apps such as CPU Spy utilizes your phones kernel to determine what your usage is. What kernel are you using for your phone? Maybe flashing a new one would help.
I'll look in to the issue more and post any other solutions if I find any. Good luck!

1) I understand that its not too safe to mess around anyhting in that directory. But.....can regular rooted users with RE edit that folder? If so, its a problem I'm experiencing. If not, then probably because that folder is in use. When I enter /sys, its mounted as r/w but there is no option for me to change it to r/o.
2) Everything is stock. I understand that CPUSpy may not work on certain custom roms, but what about stock?

The app may not be compatible with a stock ROM/kernel. Hopefully someone else on a stock ROM can help you confirm that.

That's a possibility.
However do you know why or how I can get cpu spy to work after I use set cpu?

I've never needed to use CPU Spy as SetCPU is more than enough, so I apologize if for not being able to answer that question. It just seems like a compatibility issue with what you are currently using, nothing for you to be worried about.

USB OTG without external power supply

Hello! Most devices like Nexus 4 or our S4 Mini have problems with USB OTG functionality - they can't provide power to connected device. When I was browsing through some system folders, I've found a directory /d/regulator/8921_usb_otg/8921_usb_otg. In this directory, I can see voltage values, but I'm not able to edit them. Can someone help me how to edit max_uV and min_uV files? Folder called "enable" can be changed to 1, but other folders no.

Hi guys!
The "file" you are trying to edit is not a file, but sysfs node.
To set or read a value you do this:
adb shell
su
cd /d/regulator/8921_usb_otg
echo 1 > enable
etc...
try to set max_uV to USB voltage which is 5V, it's in uV so:
echo 5000000 > max_uV

Q Removed execute permissions for system-app folder

oh no. sometimes i just have to wonder, how i can suck with computers this much.
this time I managed to root my nokia x 1.2.4.3 right but went to change permissions of whole system-app file by removing execute-rights and naturally the whole phone aint anymore managing to open OS. So my dear and hopefully more skilled friends, how I can change permissions of system-app folder back to regular from PC
Seems that there aint any difference when trying to open phone with volume up or down.
tommi
EDIT volume up seems working out but not sure what i should do with it to change system app permissions to default

So what do you guys think is nokias own hard-reset going to help me or **** me even more over?
Also is there possibilty to change permissions of this files through computer? I could imagine tat superRU is also installed to system-apps folder so cant probably start it to give permissions to access changing permissions.
Im just lonely homeless traveller who wants to abuse tinder for finding places to sleep, cant be too much to asked.
