[GUIDE]Moving Dalvik-Cache to /Cache -Viewpad 7 Tested

Moving Dalvik-Cache to /cache
Notes:
If you want to move the Dalvik-Cache to /cache you will needed to the following:
1. A Viewpad7 or another branded device (such as: Cherry Mobile Superion, Commtiva Linx N700, Olivepad VT-100, Spice MI700, and Camangi FM600..........)
2. Already got the root permission (For running a set of command)
3. ADB or Terminal Emulator (For running the command)
4. Root Explorer(Optional - if you have a lot of patience for typing)
Steps
1. Build a file call "install-recovery.sh" into the /etc (Path: /etc/install-recovery.sh) With 711 Permission. (Or you can build it in your computer and put it in the sdcard then copy it using Root Explorer.
Code:
#!/system/bin/sh
chmod 771 /cache
2. Move your dalvik-cache and Create Symbolic Link
(You may experience some program FC (Force Close), but never mind)
Code:
mv /data/dalvik-cache /cache/dalvik-cache
ln -s /cache/dalvik-cache /data/dalvik-cache
You've done the action!
If you got a LOT of FC after move the dalvik-cache.
Please go to /(Root) to check the permission of the /cache it may be become 770.
Remarks:
I think it is able to do the same things to a SD Partition or A2SD.
However I have try it. (Because I still haven't install the Custom Recovery.)
If you have any problems. Please leave a message here.
If you want to forward this message. Please provide the source URL in your message.
DISCLAIMER: I cannot be held liable for anything you do to your Viewpad 7 (or equivalent device).
[DISCLAIMER Copy from lakehousetech thanks for your DISCLAIMER.]

Will this still works, after reboot ?

Yes It will be. The install-recovery.sh scripts will be automatically run everytime you boot up the viewpad 7

i found a more efficient method, moving dalvik chache to sd card partitions... using rom manager and link2sd..

Hah same here And it works great

Could either of you guys who are using ROM Manager/Link2SD provide instructions for how you set that up? Thanks!
Edit, a few days later. Disregard, figured it out on my own. For anyone else interested...
If you're one a Windows based machine, download this, and use it to create an ext2 partition on your SD card. Personally, I copied the contents of the SD over to my computer before I did so, then copied them back after I was done. With link2sd, you can just adjust all the "user" apps to link to the SD, and set it up so it does likewise on install of new apps. Very easy.

**Insufficient Space Available**

So I've searched around and found that others have had this issue as well but no resolution yet. I am on a T-mobile Galaxy Tab 7 running Overcome 7 Series v 4.0 and I am unable to download apps larger than what appears to be about 25mb or larger. I keep getting an error saying that I have insufficient space available though I still have over 1gb of storage available. I ran into this issue while running Overcome Kratos as well.
Is anyone else still having this issue? If so, post here which version tab you have and what rom your running.

The problem lies in the new Android market place app. It is quite buggy from what I hear. A work around is to uninstall the update via the settings -> applications menu. This will revert you back to the old market place version.
Alternativly, I hear there are updates that you'd have to install manually that patch the bug.

I have tried both to no avail.

You can fix if you have root in you tab.
First download and install Bloat Freezer Free from the market.
With this you can freeze the Market Updater.
Later uninstall the new Market app.

Maybe it's something completely different.
I had quite the same problem ("database full, please delete some contacts/messages") and couldn't find anything.
UNTIL ... i got the idea to check the trash of the Samsung email client.
I used email via POP3 and "delete" doesn't delete a mail, it pushes it to the trash bin (which isn't shown by default).
So I found out that I had one year's email and SPAM blocking my database (which did not show in any tool.
Unfortunately (again) there's no "empty trash" option, so I deleted the POP3-user and am now using IMAP without any problems.
Perhaps this helps someone.

Any news on this? Just installed Overcome today and is experiencing this issue.

If you have clockwork recovery clear dalvik cache

The problem lies in the default cache partition, which is small. If you're rooted, here's a fix that worked for me.
prerequisites:
root
Script Manager (ads version works ok), or any Terminal app
1. run script manager and bring up the Console
2. Type ’su’ (minus the quotes. approve root permission request if it pops up)
3. Type ‘cd /’
4. Type ‘umount /cache’
5. Type ‘mount -o rw,remount -t rootfs rootfs /’ (set read write permissions)
6. Type ‘rmdir /cache’ (delete cache folder)
7. Type ‘mkdir /sdcard/cache’
8. Type ‘ln -s /sdcard/cache /cache’
(to link cache folder to /sdcard/cache for a bigger partition size)
now your cache will sit on the /sdcard/cache folder, so your cache size is as large as your sd card's free space. I just found this fix somewhere, i forgot where exactly but props o whoever came up with it.
This doesn't seem to stick after a reboot, so maybe you can write a script file and run that at boot using Script manager. I prefer to do it only before I have to install something big, which is not very often anyway, so just run the script when you have to so you can keep default settings at bootup.

[SCRIPT] Simple Dalvik Cache Cleaner

Dalvik cache cleaner is a shell script which clears the Dalvik cache that can be used with Android Terminal Emulator.
Root and busybox is required, if you don't know what root and/or busybox is then do NOT bother using the script.
Place the shell script in the main directory.
With Android Terminal Emulator type:
su
sh /sdcard/Dalvik_cache_cleaner.sh
The process should be close to instant depending on how much files you have in the directory.
Download: http://caftp.3owl.com/Shell_Scripts/Dalvik_cache_cleaner/Dalvik_cache_cleaner.sh

It worked

Is this also intended to run on every boot, ie via init.d

No, that would also waste too much time on boot then on a normal boot due to rebuilding the cache everytime.
When you uninstall an application, usually a dalvik cache file is left over wasting space.
But if you want you can use ROM Toolbox from JRUMMY APPS INC. in the Play Store.
There is a Scripter in that application that you can use for such thing but the problem is that when I tryed using the su binary in the shell script, there is an issue where the su binary in the shell script will just cut off the other parts of the script and only the su binary so your answer would be fat chance unfortunately. :/

Is this the same as wiping dv cache through recovery. Also what will be the script for wiping cache? Will it be rm /cache?
Thanx!

Yes and the code is:

I'm not sure if /cache/ is really dalvik cache, on devices with OTA update support the OTA zip's will be stored their with other stuff but if you want I can give you the code for that.
On linux (That also means android) use 'chmod 755' for the permissions for the shell script.
I have tried adding 'su' but that fails has the terminal only executes the su binary so the rest of the script does not get executed.
Using the 'echo' binary to say out what it is doing is a fail has the terminal does not go anywhere due to the echo binary getting executed but it will not display output in the terminal anyway making the script not being executable.
Sent from my Sony Tablet S using xda premium

Man I am full with ideas.
I can create a shell script to do:
[OTA]
Remove OTA Update zip in cache
Copy OTA Update zip from cache to SDCard
[Files and Folders]
Remove LOST.DIR (That is just a useless folder )
Wipe SD Card
Wipe Zip files (useful for custom roms on your SD which you don't want anymore)
Well soon I should get more ideas so the OTA shell scripts will not be possible unless I get a rootable device with OTA functionallity (I do have a Sony Tablet S but I forgot to root it but I went and installed the firmware update without noticing) so it would be the Nexus 4 I would test it on in March.
The thing is that more shell scripts I create more pages I have to add to my website to give information about it, how to use it and the download link which can take around 10 Minutes just by editing the code, make backup and then upload via FTP.
Sent from my Sony Tablet S using xda premium

New shell scripts available which should be available tomorrow and if not a few days.
They are:
Aptoide Cleaner - I found out that the xml files are adding numbers to their file extensions so I built a script which can remove that problem real fast.
Take Out Bin - Removes all or at least most useless directories like LOST.DIR and LazyList, they are just a few.
ExtSD and USB Cleaner - Same has 'Take Out Bin' but it does it on the external SD Card while on USB, LOST.DIR will be erased has that should not be there.
-OLDER PROJECTS-
Dalvik Cache Cleaner - Read the first post.
Andro.Shell.Crash - This is good for developers has this does crash/lag/freeze the OS which can help a root exploit get in, of course there is different effects depending on the hardware and software, if the device is fast and has good hardware then it is possible that it may just lag and/or freeze but for older devices with older hardware can just crash.
NOTICE: The older projects are already out and available to download on my website.
I will be creating a forum about these shell scripts but I am not sure about the Aptoide one for many reasons.
I know that I am not suppose to be talking about this on a thread which has a different purpose but yeah, just an update.
EDIT: I uploaded and programmed the webpages from my tablet using WM FTP Client and DroidEdit Pro so that was a bit too early but all well, new thread(s) should come in tomorrow depending what will happen tomorrow (It is 03:30AM so it would count has today anyway).

Anyone can please guide me how to remove this script???
Thank you in advance

You just delete the shell script, you only use it in the Terminal Emulator so once you run it, it will wipe the dalvik cache so it will not do such thing in every boot.
Sent from my Nexus 4

Man I think you should create a script which are:
Auto clean of cache || Optimize App || Kill Media Process
If it's possible to you to create script with the list below that will be awesome ! ..
what is the code for auto cleaning cache every 30 minutes ? ..
and also auto optimize application every 24 hours ? ..
kill media process ?
I hope you could help me with this .. Thanks !

That's because I switched sites between 2012 - 2015. This thread was very inactive so I missed it out and didn't update the link with the new one.
The current server I use for it has some files that I'm aware of that are more often downloaded by users which means I ended up removing the shell scripts along with others that don't need to be there. I made a backup of everything before, by the way.
I don't feel that there's a need restore the file and plus, this thread's old.
Because of the sudden bumps of a thread that currently serves no purpose, something should be done about it to avoid further confusions.

Can you please tell me what your script did.
I made my own script that does
su -c 'find /data/data/*/cache/* -delete'
This one line saved me from installing multi-megabyte apps that do the same thing.
Is there anything more I should add to my script?
Now I can finally have enough room so Google Play can update apps again!

[MOD] [GUIDE] Save /data space and use that /cache partition!

LINK TO THE THREAD WITH THE AUTOMATED SCRIPT (thanks to @skyguy126): http://forum.xda-developers.com/moto-g/general/mod-storage-reloacting-dalvik-cache-t2953616
Hello everybody
as you may know, our Moto G's internal eMMC card has a ~600Mb partition called /cache, which is not used since the apps' cache is stored in /data, so the latter fills up and the first one stays empty.
Owning a 8Gb model, having 600Mb not available for storage really bugged me, because my phone's memory (/data partition) was always full because it's a 5.7Gb space shared between apps and microSD files.
Well, thanks to @skyguy126, who linked me to this guide, I managed to link the dalvik cache files to the /cache partition
Now, it may not work for you if:
a) you have A LOT of apps installed.
And by "a lot", I mean more than 90-100 apps, but if you have a 8Gb model, you probably don't :laugh:
b) you're running ART
Since ART uses a lot more space than dalvik, the space in the /cache partition probably won't be enough. When I was running ART, it used 1Gb more than dalvik.​
Other than that, all you need is a rooted phone, the Terminal Emulator app installed (HERE), a root file manager, at least one hand and a working brain
I TAKE NO RESPONSIBILITY FOR ANY DAMAGE THAT HAPPENS TO YOUR PHONE, CONTINUE AT YOUR OWN RISK.
Steps:
1) Open any text editor, messaging app, notes app or anything that allows a text input. write the following line, select it and copy it to your clipboard (you'll need it later).
Code:
ln -s /cache/dalvik-cache /data/dalvik-cache
Also, make sure you open the Terminal Emulator app and type in "su" (without quotes), then grant it superuser access. You'll need to switch to it quickly.
2) Open your root file manager, while making sure you still see the terminal emulator's notification (I used Root Explorer but any other app should work just fine), go to /data, select the /dalvik-cache folder (just to be sure, hit "properties" to check its size. If it's less than 600Mb you're good to go. If it's not, this won't work, sorry) and move (NOT copy, MOVE) it to /cache. If it asks you to merge two folders, do it.
NOTE: now some apps may start force closing, it's normal, keep going
3) Switch to the Terminal Emulator app (via the recents screen or by tapping its notification" and paste the text you copied at the beginning by long-pressing the black screen and hitting "Paste" (DUH?!?), hit enter, make sure no error messages come up, then reboot.
TA-DAAAA!
Your dalvik cache is now linked to the /cache partition, enjoy that half a gigabyte
If you need any help, feel free to PM me
"But Bert, what if it doesn't work and my phone explodes?"
Well, if it blows up there's nothing much I can do, but if it's just stuck at bootanimation/bootlogo/somewhere where you can't use it, simply head to the recovery and wipe dalvik-cache. This will revert the process and delete the link, putting the phone as it was before

To get it working just wipe dalvik cache in cwm, it will re-create directory in /data.
I had the same issue..
I will try to investigate what went wrong with this....

jaja Thakyou, that work.:fingers-crossed:

I have found an issue. When you are copying /data/dalvik-cache to /cache/dalvik cache permissions can be mismatched (different partition type).
To fix it just:
- Go to CWM
- Connect phone to PC (should be recongnized as ADB device, if not check in Hardware Manager how it was recongizes)
- issue "ADB shell" command
- in Android shell: chmod 644 /cache/dalvik-cache/*
- reboot and you are done
I have made up an easier way to achive dalvik-cache on /cache partition:
On running android:
- make sure /cache/dalvik-cache folder is empty!!
- Rename /data/dalvik-cache to /data/dalvik-cache2
- ln -s /cache/dalvik-cache /data/dalvik-cache
- reboot and done
Android will recreate dalvik cache in /cache/dalvik-cache dir, it will take about 10 minutes, so be patient
if something goes wrong, just rename /data/dalvik-cache2 by ADB (e.g. in CWM)
I hope if was helpfull.
Cheers,

good work
Thank you for this. I will definitely be doing this.

You should make a batch file that does this whole process automatically. I would be happy to assist!

It's up to 600mb. It's what ever size your dalvik cache is. I don't think this will work on android 5.0 since the change to art.

[MOD][SCRIPT] Get More Storage by Relocating Dalvik Cache!

DISCLAIMER: YOU AGREE TO TAKE FULL RESPONSIBILITY FOR YOUR DEVICE IF YOU PROCEED.
The original thread (http://forum.xda-developers.com/moto-g/general/mod-save-data-space-cache-partition-t2942765) was getting to cluttered up with development and testing so I decided to start a new thread with the "finished" product. The original thread will be renamed to Q&A/Development. We might even ask for the old thread to be closed down. (up to @Bert98, the thread's creator.)
Moto G's internal eMMC card has a ~600Mb partition called /cache, which is not used since the apps' cache is stored in /data, so the latter fills up and the first one stays empty.
Owning a 8Gb model, having 600Mb not available for storage really bugged me, because my phone's memory (/data partition) was always full because it's a 5.7Gb space shared between apps and microSD files.
Now, it may not work for you if:
a) you have A LOT of apps installed.
And by "a lot", I mean more than 90-100 apps, but if you have a 8Gb model, you probably don't
b) you're running ART (this is default in lollipop and newer)
Since ART uses a lot more space than dalvik, the space in the /cache partition probably won't be enough. When I was running ART, it used 1Gb more than dalvik.

This was tested on my moto g 16GB which is running RetailUS_4.4.4 kitkat with CWM recovery. The custom ROM procedure was tested on the same phone but with cm11 Nightly installed.
Prerequisites:
1. You must have "adb root" functioning. If you don't head to this thread: http://forum.xda-developers.com/showthread.php?t=1687590 and there is a free download link at the bottom of the post.
Download and install the apk on your phone. Open up adbd insecure (the new app) and grant it superuser rights PERMANENTLY. Check the box that says "enable insecure binary" and make sure to check the box
that says "enable at boot."
2. You must have a recovery that can accept adb shell commands.
3. Root Access Duh?!
4. A windows machine capable of running batch files.
5. A decent text editor, notepad will work but notepad++ is strongly recommended. (Only needed if you are using STOCK ROM procedure)
Please, please make a nandroid backup before you continue!!!!
Stock ROM procedure:
Read the directions very carefully and then read them again, before continuing.
1. Download the cachemover_v1.3.zip from: LINK REMOVED DUE TO SCRIPT ISSUES.
2. Extract the contents.
3. Connect device to PC and navigate to the extracted folder.
4. Double click/Run the cachemover_Stock.bat
5. Follow the onscreen instructions until you get to the part where it says to edit a file.
6. About halfway through the script it will pull a file called "init.qcom.post_boot.sh" to the folder.
7. Open it with a TEXT editor and navigate to about line 487 (Might be different for 8gb model). Look here for a better understanding: https://www.dropbox.com/s/jr5lyl5s5i2jtpg/where to paste code.PNG?dl=0
8. Start a new line and paste this code in the file: (Refer to the image above for help)
Code:
chmod 655 /cache
chmod 655 /cache/dalvik-cache
chmod 655 /cache/dalvik-cache/*
9. Make sure to save the file in the same folder as the cachemover_Stock.bat
10. Press any key to continue on the script and let it do its thing.
11. It will reboot several times and land you on the home screen/lock screen.
12. If the script hangs after a reboot, you need to unlock the device to reestablish a connection with your computer.
13. There might be one or two force closes but once you close the notifications they will not come back.
Custom ROM procedure:
USE THIS FOR ROMS THAT DO NOT REMOUNT OR CHANGE PERMISSIONS OF /CACHE ON BOOT
1. Download the cachemover_v1.3.zip from: https://www.dropbox.com/s/bzj34g4q1s61ojz/cachemover_v1.3.zip?dl=0
2. Extract the contents.
3. Connect device to PC and navigate to the extracted folder.
4. Double click/Run the cachemover.bat
5. Follow the onscreen instructions.
If anything goes wrong:
Go to recovery, wipe cache, then wipe dalvik-cache and reboot. This should get your device back to how it was.
(If you used STOCK ROM procedure)
The script made a backup of the "init.qcom.post_boot.sh" file to /sdcard/init_backup
You can restore the shell script to /system/etc/ via shell commands or by using a root browser. To restore permissions:
Code:
chmod 740 /system/etc/init.qcom.post_boot.sh
chown root:root /system/etc/init.qcom.post_boot.sh
Custom ROM procedure already has a restore script!
I am currently working on an auto restore script for stock and that will be relased soon, hopefully! :good:
Changelog:
v1.0 - First stable release. Does not work on STOCK ROM.
v1.1 - Added a restore script.
v1.3 - Added support for STOCK ROM. There are still a few bugs.
How it works?!?!
Coming soon...
Huge thanks to @Bert98 and @dd043
Hit the thanks button if it worked! I went through about 50 factory resets, and reflashed the ROM about 25 times, and put about 10 hours of work into this script! Really motivates me for future projects. :laugh:

Thanks for your help man and effort.
I encountered a problem, everything works up until my device boots in CWM to fix permissions, then just sits there doing not alot I don't even see the option in my CWM.
Any ideas? cheers

When it reboots to cwm unplug the cable and replug it, if it hangs just type these commands manually from a command window.
chmod 655 /cache
chmod 655 /cache/dalvik-cache
chmod 655 /cache/dalvik-cache/*
reboot
If this does not work you may ned to go into mounts & storage in the cwm menu and click mount /cache. Then try the commands again.

I'm having some issues on stock.
I thought 0655 fixed everything but no, I can't install any app after moving the dalvik-cache to /cache. I tried chmoding 0777 on the new cache folder, on /cache itself, to no avail.
Code:
E/dexopt cannot open '/data/dalvik-cache/[email protected]' for output
Anyone can confirm it's not only my device? And/or can help find a fix?
Also does someone knows how to execute commands on a particular init step? Real init.rc scripts can do:
Code:
on post-fs-data
mount -o bind /cache/dalvik /data/dalvik-cache
It there was a way to achieve the same from post_boot/init.d we could mount -o bind /cache/dalvik /data/dalvik-cache and all permissions issues would disappear as well as the need for symlink.

You have a typo in the threads title. Just a heads up.

Let me try and do that right now... Ill get back to you if it does!
My script works on stock btw... But the mount way seems a bit easier and might cause less errors than my way.
Try it please.

Yes I've tried your script, all went well but the result is the same. The script itself works nicely btw
Applications present before moving cache work perfectly, but I can't install anything new. I suspect it might be my device but before wiping everything I'd prefer feedback from others :fingers-crossed:.

I cannot install new apps as well. The mount command you showed me has the same effect too. I honestly don't know anymore, the sym link did not allow the install of new apps nor did the mount command you sent me. Correct me if I am wrong.
Edit: Going through all the init files on my phone to see which one remounts /cache at boot.

Why does the init.rc get overwritten at boot. Is it because the kernel (boot.img) is the one that copies it over? I have found by changing the perms/locations in this file and init.target.rc you can achieve what this mod is trying to acomplish.

I don't see the mount cache command in CWM strange
I've managed to get back to normal, thanks for everyone's help though, I will keep and eye on the thread

non-windows version?
Thanks for this tool. It's a great idea and our Motos really need it.
However, I have a problem - I do not own a windows license (os x and ubuntu user) and I would prefer not to spend $120 just to use it for this script. Pirating is out of the question for me.
I was wondering if there is any chance of having this script written for linux and/or mac. If impossible, is there a LEGAL way of running windows in a virtual machine? Something like a trial or similar?

If you know how just convert it to shell script for osx and Linux. I give you permission to do this but you may not take credit or rehost your creation.

Ok so I have the kernel extracted and we could modify and flash that, but I believe that it's not really necessary. There are a lot of risks to flashing kernels and I am not willing to take it. So is there a way we can modify dalvik so it creates it's cache in /cache instead.

Yes the init.rc is in the boot ramdisk. I don't think it would be worth the trouble to rebuild a boot.img. The moto g is fairly unbrickable but it's quite a lot of work to setup an environment to rebuild an image :/.
Too bad for the mount command, I was sure it was working but maybe I had changed something else and don't quite remember the steps to reproduce
We could possibly implement a shell script toggler for when we need to install new apps, but I'm afraid it'd become annoying fairly quickly: I noticed the issue initially because google play services decided to update itself, failed, and broke all google apps. As far as I know this autoupate can't be disabled.
Thanks for trying!

How about making a simple apk that toggles this feature. Something like when you click the icon it doesn't even open but gives a little notification of success. Something like that. I myself am not experienced with apks but I can put together a shell script for the apk.

Patching dalvik itself sounds promising. It can probably be done with in a batch script with a command line hex editor.
The path is defined in frameworks/base/cmds/installd/installd.h
Code:
#define DALVIK_CACHE_PREFIX "/data/dalvik-cache/"
Not sure if there is another mention in the source tree.
But there's nothing to say we wouldn't face the same issue, the error message in the logcat is pretty generic

Ill try it. I don't mind doing a bunch of resets because I am using my moto g as a test bench anyway. My daily driver is the OnePlus One

EDIT: Unfortunately it didn't work. I don't know if I modified the installd file correctly. The program I used is HxD.

Is there a way we can force dalvik to start after the directories are created. And change dalvik to create it in /cache.
