REQUEST/IDEA for a safety script for tweaking/OC

I had an Idea for a script that would run at bootup, and if a certain variable had a "value" of NOT 1.
then the script would change the CHMOD of a userinit.sh located in the sd-ext from 050 or 777 to 750 then it would change the variable "value" to 0 were it would stay untill another script that runs at shut down or reboot setts the variable to 1 and changes CHMOD back to 050 or 777 so that the userinit.sh is not run.
That way if a change is made during operating the phone that causes the phone to crash with out shutting down properly the script runs which causes the userinit.sh to run and "resets" userinit.sh values to a "default". Otherwise if shut down properly nothing happens.
This could be expanded on to include repairing the EXT or clearing some special cache or other stuff I am unfamiliar with but that you might want to run after a crash.(like logcat?)
any way what do you think? any promise?

I think, for overclocking purposes anyway, making the userinit.sh unrunnable would make the phone break immediately, as I think it would go to the highest available frequency. However, I like the idea, though I'm not sure how to run scripts on shutdown. I think for overclocking, it would check if the shutdown was clean on startup, and if not change the applicable line to the next lowest number, which it would get either from a seperate file or maybe it could be stuffed in the script itself. (Just my somewhat uneducated thoughts)

Keep it simple. If a change in userinit.sh breaks your system, reboot to recovery and edit it and reboot again.

most rom devs/tweakers launch userinit.sh by calling it with a sh
e.g.
/system/bin/sh /system/sd/userinit.sh
so it will still run !! ( as init doesn't care about permissions, it is god )
don't believe me?
Code:
echo "echo I ran" > /data/test.sh
chmod 000 /data/test.sh
sh /data/test.sh

Keep it simple. If a change in userinit.sh breaks your system, reboot to recovery and edit it and reboot again.

And I know that most roms now have a script called something like in /system/etc/init.d/20userinit that runs at startup and checks to see if a userinit.sh is present in sd-ext,if so it runs it.Also I noticed that the script can be there but if it is CHMOD to 777 it wont run. This is the "Reset script" Set to restet to something you like and run other tasks to help Fix/Diagnose probs.
The OC changes would be made from a different script such as 86supersettings
Or a userinit located in system/sd maybe ?
The thing is making sure one is read before the other.
Any way I probably will just learn the language better and do it from recovery console.
Thanks again

chmod 777 makes it rw and executable by everyone!!!!!!!!
have a look here
http://www.comptechdoc.org/os/linux/usersguide/linux_ugfilesp.html
but as I mentioned above, init ( the initial progam runs as root and doesn't care about permissions, ( it wouldn't be very good at doing initialising the system if it had to seek permission )

Yea your right. Well I said I wasn't that good at this linux stuff! Now I Proved it.
Any way as you can see this is more of a request..... I still think it's a good Idea.
Thanks for your help FireRat.

I understand how I could manualy Replace the modified script with a default one that was on my sdcard from within recovery after a faild OC change...but..
Are you saying I could actualy modify the original script from recover? Do you have any info on how? A link?

If you have RA-Recovery, adb works, so you can pull/push the userinit.sh script. You can also enter the terminal and use vi to edit it from recovery. You may have to mount the ext partition first, but that's pretty easy. "mount /system/sd" will do it, if /system/sd doesn't exist, "mkdir /system/sd".

Ok, Thanks that makes sense. I'm still learning adb though. And I tried vi once before with no luck. But now I know what to learn about.
Thanks a lot I appreciate it.

I'm not sure you need it,
this is for education value, if you want to play ^^^ is where to start

Thank You!
That is perfect
I need to add all of this to the startup script right?

I am going to use the beta boot up script from ZKX called 86Supersettings, but I could use a userinit/user.conf like most do. Correct?

well, a .conf file should be just that
a file with configurations , not an executable script

OK. I guess I meant both together. I would use the user.conf to make tweaks. Then have to modify the userinit.sh with the part you made. Something like.
#!/system/bin/sh--LEAVE THIS OUT. ITS ALL READY AT THE BEGINNING
if [ "`cat /data/cleanshutdown`" != "1" ];
then
echo "shutdown was not clean"
Dont run user.conf
and set cpu or other stuff to "default"

Run user.conf for tweaked settings

If I'm way off then I guess I need to re-read the Userinit thread.

well, in practise it doesn't matter
the file extension is only for use humans, if I'm looking in a directory and I see .conf I expect it to be a configuration file, I see .sh, its a shell script, .py python, pl perl .......

I see. Well Thanks again for your help. Your script does work. I tried it. crash on purpose.
I still have a lot to learn.

Folks;
1) If you're OC'ing via SetCPU, remember that this doesn't change the recovery kernel, and you can uninstall SetCPU from Recovery. From there, all you need is a "safe" userinit.sh.
3) If you're OC'ing via userinit.sh -- same deal. Your phone crashes on you and you just edit it to a safe config from recovery.
Tweak away.

This is what I ended up with

Named 86supersettings so it runs after userinit.sh if one exists.
I put some Led indicators in so you can tell if it ran right at boot up. (about all I did besides copy and paste) Thinking about adding some other stuff like repair ext, or some kind of log to help me see what happed... any suggestions.

OK, here's another Idea for another safety feature...
I would like to "hard code" a temp fail-safe in to the code. I would like to get rid of SetCPU and when OC-ing it's nice to have a temp failsafe.SHUTDOWN!LOL
Any way I guess I would just add a few lines to some existing script in my phone?.... Any suggestions.
Thanks for your time.

zRam on Gingerbread

Ok so the reason why I made this topic is because Coertmans asked me about virtual ram in android (2.3.6), which is available in CM9, so I went surfing on the interwebs to find about this zRam, first thing I found was this:
Site: http://code.google.com/p/compcache/ (ramzswap_32a.ko/ramzswap_32b.ko)
Instructions: http://code.google.com/p/compcache/wiki/CompilingAndUsingNew
This is the link to the zRam modules for linux kernels, as I'm not sure if it's able to import it into GB I continued searching and found a GB ROM (CM7) which has zRam. I downloaded the rom and searched for the files that possible could be the zRam. All ram/swap related items I got are these:

About SWAP!
ROM will activate 3 kind of swap
It's will turn ON (only if you have already created swap file on partition, or set partition for swap (the hard way) )
SD-EXT SWAP
SD-SWAP
EXT dedicated SWAP partition
***If you have SWAP already, or EXT or SD-SWAP/EXT-SWAP, no need to run the swap activation scripts.
***I have created 2 scripts for disabling SD swap before use of USB storage.
I have put them in your /sdcard/gscript
so you only need the app (gscript light or full)
then load this scripts, when you need usb storage run swapoff script. when done run swapon.
or you can install dual mount app. i can’t live without it so try it.

SD SWAP THE EASY WAY!
In Easy way Swap you don't need to reformat or even reboot your phone to create swap!
If you installed my ROM and you don't have swap but you want to stay on HIGH END ROM,
Then you can do this to enable SD swap

So what do you guys think about it? It seems to me that this is really possible on GB

This is what I tried so far:
Code:
adb shell
su
mount -o remount rw /system
busybox dd if=/dev/zero of=/sdcard/swap bs=1k count=250000 > /dev/null
busybox mkswap /sdcard/swap > /dev/null
echo "/sdcard/swap swap swap" >> /system/etc/vold.fstab
echo 50 > /proc/sys/vm/swappiness
swapon -a
Now I don't get an error, but also nothing seems to happen, I'm going to try to make the sdcard "swappable ready" the manual way now
edit: Hmm I can only pick my internal sdcard for partitioning the sdcard, someone knows how to do that for external?
And how can I see if the virtual ram is actually working?
btw here is the mirror with the files I used: http://www.bourseanalyse.fr/dorimanx/
btw, totally of topic, but I saw 2 cars on fire so I made a video

The easiest and the only way i know of to check how ram, swap, and memory is used is by going into Terminal Emulator and typing in "free" and click enter... (without the quotations)

Ok thanks, used: "free | grep Swap" seems it's not working yet.

Hello
do you know the app swapper2 ?
it do the same what you try to do here !
But in the german forum there are some people who bricked their device with this app so i just want to say that you really have to pay attention with swapping

they bricked it because of partition of internal sdcard If all of us will partition internal sdcard we have more than 50% chances to brick our device. It seems that partioning internal SD affects the 1-8 boot partitions (dunno how to explain it better) I`ve just woke up lol

Also we need a kernel that supports swap
And we don't have such a kernel

Ok thanks, used: "free | grep Swap" seems it's not working yet.

if u are getting all 0's in swap then it is not working... i thik you can try going thru htc dream (G1) gingerbread roms.... they used swap and zramk a lot... well it was essential for the rom to run on that device
If it looks like this (with zeros in the swap line), you do not have swap/compcache:
total used free shared buffers
Mem: 97932 96640 1292 0 272
Swap: 0 0 0
Total: 97932 96640 1292
If it looks like this (with anything other than zeros in the swap line), you do have swap/compache:
total used free shared buffers
Mem: 97932 96004 1928 0 332
Swap: 24472 0 24472
Total: 122404 96004 26400

I had a swap partition on my galaxy 3 and i just wanted to say that it isnt fun...it makes the phone laggy cause you can never have a sd-card which is as fast as a ram module
Sent from my GT-I9001 using XDA

Yes! SDcards even class 10, ain't that stable. Anyhow what's the big deal ?
we never fall short of ram on our device.
Had tried ram swapping on my I9003 and i managed to screw up everything,made it a paper weight (Hard bricked it).
Had to get the board replaced from samsung, on the good side i got the latest latona board with 16gb onboard memory
but i no longer have the i9003

I tried swap while I had Galaxy 3 (it only has 256MB RAM) and I didn't like it. Also many other people reported that it was only slowing down system (even with class 10 cards) SD Cards just aren't fast enough to be used as a RAM...plus, Android is based on a though that free RAM is wasted RAM, right? 512MB for our phone is enough for me, and I've never fallen short of RAM..swap is not needed..but that's just my opinion

I'm not going to continue on this anyway, making your sdcard a swap drives really ****s it up, when I tried to install an app my phone shut down..

How to change CPU governors and I/O schedulers
Guys. I created a cputuner script for all devices and not just for MMX. The code is given below. Just copy it in the file and name it cputuner. Run the script using SM. The settings will stick in every reboot.

Bro can you upload your sources to guthub and is it possible to build cyanogenmod from your kernel build.
You ve done something very great dont think im asking again n again juz upload your siurces to github which is your modified sourcr used to build this kernel it will be very useful for most of the mt6577 who are missing something in the sources...

[Help][Bash][build.prop]Developers only!

Hello everyone, i just wanted help with my Bash script!
I usually flash nightlies and when ever i flash them, i lose my tweaks
So i decided creating a bash script for myself,
Here's how it is....
Code:
#!/system/bin/sh
## personal file
tweaks=/sdcard/tweaks
build=/system/build.prop
## loop trough $tweak
sed -r '/(#.*|^ *$)/d;/.*=.*/!d;$a' $tweak | while read line
do
## get entry from $tweak
entry=$(echo $line | sed "s/=.*//")
## if variable already present in $build
if cat $build | grep -q $entry
then
## override value in $build if different
if ! cat $build | grep -q $(cat $tweak | grep $entry)
then
sed -i "s/^${entry}=.*$/${line}/g" $build
fi
else
echo $line >> $build
fi
done
Everything works but i wanted to keep this process running (For testing purposes),
I mean after my tweaks/values get replaced, i want the same thing to happen with other values!
Eg:- /sdcard/tweak= Contains line= ro.build.model=Nexus 5,
Same file contains ro.build.model=Xperia Z,
now what i want my script to do is, First replace my phone model with Nexus 5 and after some time change it with Xperia Z without starting/stopping any other script!
But i aint too good at this!
So i require a helping hand!
I hope you get my point.

i caught a typo:
tweaks -> tweak
and,
First replace my phone model with Nexus 5 and after some time change it with Xperia Z without starting/stopping any other script!
why dont you try something called 'sleep' command? its very very convenient
for example:
Code:
sleep 60 #will make the script suspend for a minute

Tweakprop can handle build.proo tweaks. It grap the new build.prob against the tweaks file you created and add this to the new one. This is flasable under cwm/twrp and works quite good.

[MT6582][init.d Tweaks][Mix n Match]-[ALPHA version]

INTRODUCTION
I am using MTK6582 device Agua Rio (close relative of Wiko Rainbow, Explay Fresh, Blu) for 4 months now and to be honest I really enjoyed using this Android phone and so I began searching for effective init.d tweaks that will be compatible for my phone. No offense to the other developers who worked hard on building a set of tweak scripts but most of them are not compatible with my phone. It is simply because the declarations of the path is not present in my device or sometimes they are just supported by MTK6582. So I started recreating my own scripts and have been using it for weeks and works as expected.
This is still in Alpha version so I am not expecting a 360-degree change in performance but if there's one thing I can guarantee you, they are working for the devices I've mentioned above and to prove that there are log files from where you can verify if the scripts were properly executed or not.
DISCLAIMER
I will not be held liable or responsible if you brick your device after flashing this tweak. ALWAYS HAVE YOUR BACKUP READY!
FLASH AT YOUR OWN RISK!!!
FEATURES
- Battery Tweaks (a lot of things going on here like battery re-calibration which will be done every 7 days, centisecs flushing interval, WiFi Sleep from Gaurav, Entropy tweak for battery, pm.sleep_mode)
- updated Loopysmoothness for MTK (I modified the declaration of variables so that the script can be a little more flexible - Credits to [email protected])
- VM Tweaks (experimental - modified scripts to work for MTK6582 credits to [email protected] and [email protected] of Fly-on)
- GPU Rendering (Enable GPU rendering for 2D operations)

Click to collapse
REQUIREMENTS
1. Rooted
2. Busybox
3. Kernel with init.d support
4. Custom recovery tool (CWMR, TWRP, Philz, CarlivTouch)
5. Presence of mind
6. Faith!
HOW TO INSTALL
1. Download the flashable zip file and save it to your SDcard (remember where you saved it)
2. Power off your phone
3. Press Power + Vol UP + Vol DOWN simultaneously
4. Choose Recovery mode
5. Select install from SDcard
6. Install the zip file
7. Wait until the installation is completed.
8. Reboot!
To manually Push the tweak
1. Download the zip file into your SDcard
2. Extract the files
3. Copy all the contents of init.d to your /system/etc/init.d
4. Change the permission to rwxr-xr-x or rwxrwxrwx
5. Copy all the content of net to /system/etc
6. Change the permission of "hosts" and "resolv.conf" to rw-rw-rw
7. Go to /data and add a new folder named "Tweaks"
8. Go to /data/Tweaks and add new 2 folders - "scripts" and "logs"
9. Copy all the contents from "scripts" (from the zip file) to /data/Tweaks/scripts
10. Change the permissions of all the files in /data/Tweaks/scripts to rwxr-xr-x or rwxrwxrwx
11. Reboot.
HOW TO VERIFY
With the use of Root Explorer or ES Explorer, go to /data/Tweaks/logs and you will see the log files generated by the scripts. Also if you have a Terminal Emulator, you can check that the rotational scripts are running in the background.
Oh by the way, sorry to disappoint the Antutu lovers but the scripts were not customized to satisfy your eyes with Antutu scores.
To manually Delete the Tweaks
1. Delete all the files mentioned above from your phone using Root Explorer (or any file manager like ES explorer)
2. You can leave the files added in /system/xbin/ as it may help you in the future... 'just a suggestion but you can delete it if you want.
FAQs
Q: Not working. How can I tell the scripts were actually working?
A: Check the logs stored in /data/Tweaks/logs and inspect if there are log files. And with the use of any text editor check one by one the log files for any errors.
Q: There are no files in /data/Tweaks/logs, what happened?
A: It is possible that your ROM does not have init.d support. You can try using [email protected]'s fix for that (http://forum.xda-developers.com/showthread.php?t=1933849). Then you can try using again the tweak
Q: After flashing the tweaks, I cannot connect to my VPN app like Psiphon. How to fix this?
A: To be honest, I am unsure yet why but you can try either the following:
1. Check again the permission of /system/etc/hosts, /system/etc/resolv.conf and make sure they are set to rw-rw-rw. Then reboot;
2. OR, move/delete /system/etc/init.d/11_Network, /system/etc/hosts, /system/etc/resolv.conf then reboot
Q: My Internet connection is slow.
A: You can try adding the 3G hack from [email protected] (http://forum.xda-developers.com/showpost.php?p=42185612&postcount=100)
Q: The tweak is actually useless, it is not working. Should this be the case?
A: If I was not able to help you in any way, thanks for testing and feedback. Google is our friend.
Thank you all!
Mix n Match ALPHA 3B is now available
CHANGES 11-DEC-2014:
Please refer to the notes above. for the updates .
The INSTALLER will backup your previous tweaks and any conflicting files with Mix n Match. I have also added now an UNINSTALLER in case you are not satisfied. The UNINSTALLER will revert all the changes made before you flashed the latest tweaks.
Again... Flash at your own risk!
Thank you very much​

great job man.. :good:
what version of rio you're using?
mines s5501 and running on kitkat deodexed by edmhar, is your tweaks compatible with edmhar's deodexed stock rom?

Good, i'll write governer tweaks for hotplug and post link here, i'll make different versions for more battery and more responsiveness

# Name: 12_CPUHotplug.sh
# Date: 11/03/2014
# Author: Arsie Organo Jr. - [email protected]
# Link:
# About: This is additional tweaking for MT6582 devices
# to improve battery life
# You will need your device to be:
# 1. Rooted
# 2. Busybox is installed.
# 3. hotplug

Too interested in !
But I have to ask you how to uninstall if we did not use your special one, because of I have a sad experience before...

Good question, I always make sure that anything I install I create a document or uninstaller.. however, I was too busy at work and wanted to share this to my FB friends so I published it as Alpha version and wanted to get their feedback.
Give me a few minutes and I will update the doc on how to uninstall.

Hi dhampire,
I have updated the docs for you.. in the next release I will make an backup and uninstaller so that if someone does not want this tweaks they can go back from their previous set.

Good Job ser!
Next custom rom

LOL!

Please wait on my next release within this week and try on your phone. But please check first if your device supports init.d.

Thank you very much for your response, I'll wait. I activated init.d thanks to Ryuinferno, via the terminal support.

Can you send me the logs from /data/Tweaks/logs ?
Or please let me know if you are familiar with ADB Shell so that I can give you the commands to check.
Thanks.

Hi,
Since we have a different device, can you delete 17_SetProps from /system/etc/init.d and then reboot?
Thanks.
