Swap for Samsung Galaxy Tab 3 7.0 - Galaxy Tab 3 7.0 Android Development

DISCLAIMER:
I AM NOT RESPONSIBLE FOR YOUR DEVICE OR ANYTHING THAT MIGHT OCCUR WHILE USING THIS TUTORIAL. TRY AT YOUR OWN RISK!
Credits:
[mbm] for teaching me this dd terminal method.
As we all know, for what ever reason, Samsung decided to release the Tab 3 model tablets with 1 GB of ram. I believe this system needs more ram but unfortunately we cannot upgrade the hardware. What we can do is create virtual memory or a "Swap file" that acts like ram to help our Tab 3's out with multitasking and other memory hogging tasks. Below are the steps to:
1. Create a swap file.
2. Create a script file to run at boot from your /system/etc/init.d directory.
3. Create a android system with 1GB of RAM and 1GB of swap file virtual memory.
*Remember whatever device you are using must have a rom with init.d support and be rooted.
STEP 1: TERMINAL COMMANDS PT.1
Download terminal emulator from the play store if you don't already have it.
https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en
Open terminal emulator and execute these commands in order:
1. "su"
2. "cd /system"
3. "mount -o rw,remount /system"
4. "dd if=/dev/zero of=swapfile bs=1m count=600" (be patient, this step takes about a minute)
5. "mkswap swapfile"
6. "chmod 755 swapfile"
STEP 2: INIT.D SWAP FILE TEXT CREATION
Now to create a script to execute at boot every time you boot your phone. I used the app QuickEdit from the play store.
https://play.google.com/store/apps/details?id=com.rhmsoft.edit
Now open that up and put the text below in the file:
"mount -o rw,remount /system
swapon /system/swapfile"
Now save that to your sdcard (/sdcard) as "swap" (remember do not save with the .txt)
STEP 3: TERMINAL COMMANDS PT.2
Now go back into terminal and execute these commands:
1. mv /sdcard/swap /system/etc/init.d
2. chmod 755 /system/etc/init.d/swap
I kept my previous terminal session open but if you closed it for what ever reason you might have to execute "su" and then "mount -o rw,remount /system" before the two commands in step 3.
STEP 4:
Reboot and win. :laugh::good::laugh:
To verify that the process has worked, after reboot, bring up terminal emulator and type "free -m". You should see that swap has more than 600M! This will stick after reboot. If for whatever reason you want to get rid of your swap file just delete the "swapfile" file and the "swap" script. Enjoy!

My swap =0.
Sent from my SM-T217S using Tapatalk

It works!
"dd if=/dev/zero of=swapfile bs=1M count=1024"
I used this command and it made a 1KB swapfile.
"dd if=/dev/zero of=swapfile bs=1024 count=1024856" - This made a 550mb swapfile.
The tablet has sped up heaps after doing this. Thank you.

Swap using sdcard0 or extsdcard ?
Extsdcard using please version? Make you

Hmmm it doesn't working for me . I have always a Cross Link error...

Your welcome. I had adjusted the original post. Maybe you did "bs=1M" and not "bs=1m". Android doesn't like the capital "M". Also, I ended up making the instructions for a smaller swap file of 600m. Glad it helped. I know it helped me a lot !

you can do it for either or. I did it for internal /sdcard because I ran out of micro sd cards. The instructions would be the same, just replace /sdcard with /ext-sdcard (or whatever your ext sdcard is named), ignore moving to /system, and ignore the permissions step for swapfile ("chmod"). It is safer doing on /ext-sdcard but most likely a little slower.

Can you Make extsdcard why

"dd if=/dev/zero of=swapfile bs=1M count=1073741824" for 1GB?
Also, I just want to ask, if this will help enough to let me play Pokemon GO
EDIT: Just to point out, it is possible that there might not be enough space for that much size of the swap file in /system
so i stopped it in between at around 392MB. I hope that wont be an issue... Would it be?

1. mv /sdcard/swap /system/etc/init.d

When executing this command I get an error - "Failed on '/sdcard/swap' - cross device link"
Any idea why I'm getting this error?
UPDATE: According to the Google t's a busybox error that can be fixed a couple ways. Either use the command "cp" instead of "mv" or try the command "busybox" before the string ie:
busybox mv /sdcard/swap /system/etc/init.d
The above command worked for me. Cheers!

I have the same Problem

Uhmm, am I doing it right? I followed all the steps and ended up with a 600mb swapfile, but when I rebooted and typed "free -m" this appears:
total used free​Swap: 358396 48676 309720
Is this ok, or did I do something wrong?

Which ROM and kernel are you using? Looks like you have zram enabled, that's the zram swap size on my tablet as well. I've tried disabling it and running the scripts but can't seem to enable swap on the kernel I'm on. It's either zram or nothing. I'm using werewolf kernel and jasbr lite ROM

It's basically the same, JASBR lite but with the kernel that came with it, i'll see if I can disable zram

So i'm really new at rooting and flashing stuff, but I followed the original instructions but after reboot and free -m, i get
swap:
total - used - free
349 - 35 - 314
is that the 600mb total its supposed to be? things dont seem to be significantly faster...
i'm using realWelder rom and his kernal.

Swap

Hi guys. can you please help me on swap. how can i enable it and disable it. and also set it to the amount that i want it. im still a bit new to this and i have also tried to look for a guide but cant find 1. thanks

If you are on Kings rom, it may be running already.
Type #free in terminal and see if it shows swap.

It definitely depends on the rom. Some King roms he has a script you run. Other roms, all you do is go to Spare Parts and set what you want. It may be best to ask in the thread for that rom.
I remembered using this when I used CM:
http://forum.xda-developers.com/showthread.php?t=581328&highlight=swap
Enable swap
I used the method to enable swap in Linux on this and it worked fine on Cyanogen and Super-D.
I used Amon_RA Recovery 1.52 to partition my SDCARD and the new recovery lets you choose the size of your partitions.
so I created a 256MB Swap.
from a console/terminal do the following after creating your swap partition the size you want it:
1. mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system (makes system dir writable)
2. mkswap /dev/block/mmcblk0p3 (formats the swap partition on SD with swap format)
3. vi /system/etc/init.d/05userinit (make a new line at the bottom and add "swapon -a" with out the quotes this forced the swap to mount on boot if it is disabled in a kernel)
4. vi /system/etc/fstab (add a line that says "/dev/block/mmcblk0p3 swap swap" with out the quotes)
5. reboot
Hope you know how to use vi editor If not google it. "I" is insert mode and push track ball and hit 1 at the same time and that will esc you to command mode, in command mode do a :wq! and hit enter and that will save the file.
This works on all roms i have run into and no matter what others say it does help the performance.
I can make it easier (short of putting this in a script). Type each line in order and hit enter after each.
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mkswap /dev/block/mmcblk0p3
echo "swapon -a" >> /system/etc/init.d/05userinit
echo "/dev/block/mmcblk0p3 swap swap" >> /system/etc/fstab
reboot

Trouble with script for CPU clock changes

So I have my DX overclocked, but I wanted to be able to change the clock while away from my PC if something goes wrong. Currently on boot it sets the CPU to whatever I had it on before powering the phone off. Now I have all setscaling.sh files on my SD card and can't get a script to copy the files over. I can do this long hand in Terminal. These commands are exactly what I typed into Terminal to get the clock rate to change, but when I throw them into a script exactly as typed below I get all kinds of errors, starting with not being able to mount my SD card.
mount -o rw,remount -t ext3 /dev/block/mcblk1p21 /system
cp /sdcard/setscaling.sh /system/xbin/setscaling.sh
mount -o ro,remount -t ext3 /dev/block/mcblk1p21 /system
setscaling.sh
EDIT:
So I did a little testing, and it looks like even if I mount the system before running the copy command and setscaling.sh they still don't work. Is this just an anti terminal thing, or what? If I type each command by hand they work, but any of them in a script and it either gives me an error, or doesn't. Either way it doesn't do what I want.
Use root explorer to copy the files over to their appropiate system folders. (Remember to to mount r/w or it wont allow you to make changes to the system folder)...then long press the setscaling.sh and hit execute..Now go to SETCPU->autodetect-> now adjust your frequencies as you wish.

Here's what i did after reading the original thread.
1. Go to the market and get "Gscript lite".
2. Run Gscript.
3. Press your hard menu button.
4. Press "Add script"
5. Name it anything in the name field.
6. Make sure "Needs SU" has the green check mark.
7. Ignore "Load file"
8. Enter your script in the field...
Code:
insmnod /system/lib/modules/overclock.ko
setscaling100.sh
do not start your script with "su" or "sh" and do not end with either of those. Of course if your file is named "setscaling.sh" then enter that name in the script.
9. save.
10. Optional and handy - go to home screen. Long press. Add shortcut. Scroll to Gscript. Select it. Select the script you created to place a shortcut on your home screen.
11. When ever you reboot- hit the shortcut and it will start you overclocking.
If you want to check that the script executed properly - using "android terminal" from market you can enter...
Code:
su
cat /proc/overclock/mpu_opps
it will lest your clock speeds for you. You can also use gscript to create a script for this. Leave out "su" and enter only the "cat" line.
good luck.

[Q] What is terminal emulator?

Is this so i can push files through my phone, without having to do it on the computer? How does this work. Anyone have a link? I did a search and came up with nothing. Just wondering, thanks!
It's the same as a Terminal on a unix/linux box or for that matter, command line on a windows box.
Terminal emulator app will give you command line access to your (rooted) phone. You can then go into SU mode, as well.
Yes, you are correct, it will allow you to do things that an ADB shell would allow, from a computer.
You can download it from the market.
im sure that you might have known this already, but when you are using a terminal emulator, and you get root access (su), you really should follow the directions to the letter. if you make a mistake in the typing, it is possible that you could do some damage.
it is also recommended to not enter in terminal commands unless someone with more experience than you (based off their post number) reports success in completing the wanted task. so essentially, use the terminal at your own risk.
(all this is pulled from my previous post which you can find in my signature - "Terminal/adb shell commands")
Adb commands are completely different than terminal commands.
First enter "su" to get substitute user (the # sign)
Then enter "mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system" to make the root r/w
to copy files use "cp" command
to move files use "mv" command
to remove files use "rm" command
to change file/dir permissions use "chmod"
to change directories use "cd" - "cd .." will bring you back one directory - "cd //" brings you back to root
to list files in the dir use "ls"
to read/mod/combine a file use "cat"
to edit a value use "echo"
to see running processes use "top"
to kill a process use "kill -9 PID#HERE"
ex) cp /sdcard/download/myapplication.apk /data/app/myapplication.apk
If you know any linux commands then you should know your way around terminal emulator. If you want i can give you more examples just let me know. Hope this helped
What does "cat" mean?
Oh my bad i didn't see it in there, all the times i lookedO sorry.
where could i get this app?
i couldnt find it on market using keyword "terminal", "terminal emulator" or even "adb terminal emulator"

Terminal Emulator Hell!!!!
I have wiped and restored more times tonight than I can count....HELP!!!! I have a very lean rom. So lean it that it has no file explorer and I don't want to install gapps. All I want to do is install Titanium Backup (the .apk file is on the root of my SD card) with the terminal emulator and I'll be all set. I have had all different error messages, and I'm more confused now then when I started this adventur, 6+ hours ago. Any help would be great.

I keep TB on the root of my sdcard named TB.apk. Then I go into terminal emulator (it is in most roms already).
su
cp /sdcard/TB.apk /data/app/TB.apk
Then I back out of TE and TB is installed. Any commands you type in TE are case sensitive. All file names are case sensitive and spaces do not work well. So if your TB apk is "Titanium Backup-1.3.3.apk", I would rename it to something without the spaces like Titanium_Backup-1.3.3.apk.
I rename it TB.apk because who wants to type all of that?

[Q] busybox and nandroid issues

I have been experimenting with my new droid/milestone the past couple of days, odd problems which I am past now but still curious about.
Firstly after flashing the 2.1 sbf with rsd it will autoboot and screen slider will be there, then when I reboot, screen slider will be missing. This only happend when I flashed an sbf from the sbf site(2.1 uk version, not service), doing a factory reset didn't have any problem -could reboot as many times and slider would be there.... then suddenly after factory boot it would dissapear after first boot. Anyway solved this problem by installing screen mode widget after first boot after flash, solved problem, but still weird. Fixed this now but still curious about it.
Next, nandroid backup is missing from recovery menu, I have rooted and can execute root commands after typing "su" via Android Terminal emulator, so pretty sure is rooted. So why no nandroid? I thought I could do nandroid backup after rooting.
Next busybox won't install, tried the app, did the "searching system" for over an hour(not exagerrating), eventually gave up and uninstalled.
Trying to do a "manual busybox install" now, using this guide:
Busybox How-to? - Android Forums
Can't execute commands via usb/adb in recovery mode as the other guy suggested so been trying these commands both with terminal emulator on phone, and usb-debugging mode with windows shell. Using these I can go "su" and type "ls" to see files on my droid phone....but when I try to "mount /system" or /sdcard from windows I just get a print about mount options, when I try to "cat /sdcard/busybox > /system/xbin/busybox" I get a "file is read only" error.
I would like advice on how to install busybox, I would like to do it manually(because the app seems to not work for me, remember I waited over an hour while it "searched") and I want to learn to manually do stuff anyway. I tried to chmod /system/xbin too, but that didn't seem to change it from read only.
Also any thoughts on why nandroid backup is missing from my recovery menu even though my droid is rooted. I thought it was meant to appear.
I am still learning and researching, and appreciate any links or tips.

This is odd. Which OpenRecovery did you install? Androidiani? GOT? Or the "original" OpenRecovery? Are you aware, that you come into OpenRecovery by starting Recovery Mode and apply update.zip?

Using the app from the market worked like a charm for me. No idea, what might have gone wrong for you...

For remounting, try "mount -o rw,remount /dev/block/mtdblock6 /system" and for undoing this, use "ro" instead of "rw".

You should download busybox and put the "busybox"-file in the directory /sdcard. After that do:
Code:
# su
# mount -o rw,remount /dev/block/mtdblock6 /system
# cp /sdcard/busybox /system/xbin
# cd /system/xbin
# chmod 755 busybox
# ./busybox --install
# mount -o ro,remount /dev/block/mtdblock6 /system
One thought at the end: How did you root?
I rooted by flashing "vunerable recovery" using RSD lite, copied milestone-root.zip to sd card, renamed it update.zip, rebooted into recovery mode, flashed update.zip from there.
I didn't realise I had to install something like open recovery, think because I remember not having to do that on my pulse? Anyway will try and install one of those now.
Thanks those commands at the end helped, actually managed to copy busybox to /system/xbin, however the 2nd last one "./busybox --install" gave me a load of errors -all being no such file or directory, for example "/usr/bin/wc: no such file"
about 30 of those path errors. Maybe the command path "./busybox" needs to be something else?
ah, okay. sorry, I thought you already installed an openrecovery. for many cool features you will need it (e.g. nandroid, for overclocking it's not a must but a nice-to-have). please don't use GOT, it's rather old already. androidiani is okay, I think.
I think your previous attempts to install busybox via the app etc. mixed up some internal links in the device. please reboot and try again (the above steps except the "cp ..."). seems like the app tried to install busybox to /usr/bin but failed... I hope this failed attempt will be fixed by a simple reboot. otherwise it would be great to have the output of:
Code:
# su
# ls /usr/bin
No I re-flashed my main sbf and also did a factory reset to do a clean start, only thing since that full wipe I have done is rooting in the method I described, installed the screenmode widget, textedit, and android terminal emulator.
I have no such file /usr, are you sure I should have this in droid/milestone?
Here is my full output of my root system using ls:
tmp
pds
cdrom
sqlite_stmt_journals
config
cache
sdcard
d
etc
system
sys
sbin
proc
init_prep_keypad.sh
init.rc
init.mapphone_umts.rc
init.mapphone_cdma.rc
init.goldfish.rc
init
default.prop
data
root
dev
perhaps "/usr" is a sub inside one of the above folders? I tried using "find" to find it but that command dosn't seem to work since it won't even find the ones I can see with ls
I found it, /usr is inside /system... so if busybox was moved to /system/xbin, I'm guessing the ./ means install it to the parent directory which was /system which /usr is also in.
The errors I got said no such file "/usr" so It seems like it is trying to install to the wrong directory.... perhaps the command should be "busybox --install" or "/busybox --install" I don't want to experiment and mess things up before your opinion on this.

This is really strange. Maybe your busybox-file is corrupt.
Where did you download the busybox-file?
Which sbf did you flash?
So for explanation-purposes: When you put an executable or script file in any directory, you can execute it by first making it executable ("chmod 755 /system/xbin/busybox"), changing to that directory ("cd /system/xbin") and then executing it by adding "./" in front of it. The dot slash always stands for the _current_ directory. The _parent_directory has two dots "../".
If you want, you may try:
# /system/xbin/busybox --install
instead of
# ./busybox --install
Or maybe try this one:
# /system/xbin/busybox --install -s /system/xbin
Last time, I installed busybox into the directory /data/busybox, which worked brilliantly, but this path turned out to be unpractical. So I wanted to reinstall it in a different directory. I removed everything from /data/busybox including the directory itself and tried to start the whole procedure with /system/xbin. But that time it protested, that there were no files in "/data/busybox/...". Conclusion: The last busybox-install affected the second one. When I remember correctly I rebooted after that and used the app from the market *g*
My main sbf I flashed was android 2.1(uk version).
I downloaded busybox 1.17.2(won't let me post url here), was from droidforums dot net.
I don't remember if I tried all of his commands, but the last one on that forum seems to have worked.. I think......... it was:
"busybox --install /system/xbin/"
After remounting with your commands and typing the above command, I didn't get any errors, I synced and rebooted and now when I "ls /system/xbin" it shows a bunch of files/names which look like busybox commands. When I type "busybox" it outputs a bunch of commands too... so I am guessing this means it has succesfully installed? I can't say I tried these before attempting install so I have no comparison but I assume I would have a different output if busybox wasn't installed.
So assuming it worked, why would
"busybox --install /system/xbin/" work, and
"/system/xbin/busybox --install" not?
I also managed to install open recovery and do a nandroid backup succesfully
I have another short question, not specific to android but happens in all terminals I use, windows and linux alike. Sometimes I cannot execute commands anymore and it just becomes text in the terminal(just re-echo'ing my text output, without executing any functions)... can't remember specifically when it happened on my windows or linux pc shells, but on my android it happens whenever I have to give "SU" permission to the terminal, I have to quickly close the terminal and reload it again to get su access. I'm sure there is a name for this "state" where you are locked out of using commands in the shell and just typing text but I can't find a way to get out of it(without closing and re-opening terminal), there must be some key combination to be able to execute commands again in the current terminal session. If you have any idea what I am talking about?
Thanks for all your help so far.

Yes, this sounds very much like installation was successful.

typing "busybox" without the path in front of it worked, because busybox is in the directory /system/xbin, which is already in your $PATH-variable (try "echo $PATH"). So the command interpreter (shell) will automatically look up "busybox" in /system/xbin.
I had a look at the busybox syntax and it's actually
Code:
busybox --install [-s] [INSTALLDIR]
So you have to put the directory you want to install in at the end. That's what your last command makes use of

Sounds like this is just the state, when shell is busy, i.e. when the last process you started is still running and no prompt ($ or #) is displayed. You may kill the last process in linux using CTRL+C, which will hopefully bring back the shell prompt. No idea which shortcut replaces this on the milestone/droid. I never use any android terminals, but only the ADB-Shell: http://developer.android.com/guide/developing/tools/adb.html
I'm learning to build apps for android so I thought having 2.1 on my droid would be better for testing (instead of 2.2). I also have a Nexus-S with 2.3 and a tmobile-pulse with 1.5. So I want to keep the most native version on each phone since most consumers won't install custom roms, although some will get updates anyway.
I use my droid a lot when I am out and use the terminal a lot so having busybox too has given me more to play around with. I actually find my droid much better working on than the nexus s, love the keyboard and dpad.

[How To] Remove WebTopMod without root! [How To]

Since I was looking to be able to update my phone, I had to remove the WebtopMod. Since the previous instructions required me to root my phone to remove it, which was counterproductive because it would mean loosing the ability to update anyway. I looked through the WebtopMod installation scripts and came up with this guide to remove it:
View attachment WebtopModRemoveGuideNoRoot.txt
Note: I've attached the guide in a separate file, because the forum is stupid and thinks that exe, bak, odex, apk, and dex are valid TLD's and says I can't post external links. If I ever get "approximately eight" posts I'll put it in this post.
If you don't have the original backup files, look in page 3 of the howto post for removing it with root. (Thanks, MotoAtrixFan for posting it and twoeleven99 for alerting me to this)
Happy Updating!

you can update even if you are rooted you cant update only when you modify the /system or some apps
went step by step through your guide and I still cannot update - the apply_patch_check still fails at DockProvider.apk - aside from reflashing the stock SBF, what do you recommend?
Try this
Try setting the phone to usb mass storage mode and replacing the files in the WebtopModBackup folder on the sd/media area with these: View attachment WebtopModBackup.zip
The files in the archive worked for me, not sure why it wouldn't work. If those don't work for you, please post the console log.

Thanks, but something appears to be totally screwed up on my DockProvider and DockService applications on Titanium Backup - they are listed at the bottom with grey slashes through them. The crazy part is.... it works with the webtop hack, but the update doesn't see the correct files, so something is obviously messed up.
Now, by putting the files from the WebtopModBackup on the phone, shouldn't that fix the issue? Then perform the steps in your text doc? I can't believe I'll have to SBF stock in order to fix the stupid DockProvider and DockService!!
What I meant was, replace the files in the WebtopModBackup folder with the stuff in the archive, then re-do the instruction in the text file.
I'm sorry but your instructions aren't working for me. I've followed your instructions very carefully but when I get to the command
cd /mnt/sdcard/WebtopModBackup
I get a directory not found error.
I can change to /mnt/sdcard but when I type 'ls' nothing appears. The directory is empty.
What am I doing wrong?
One thing I've noticed is that when I enter the 'adb.exe shell ./data/local/tmp/psneuter' command, the phone appears to dismount and remount and then when I go into the shell the '/mnt/sdcard' directory is empty.
Yeah I'm also having that problem....I'm trying to push the backup files into the correct folder. However, when I get a read-only error, so from what I read I'm supposed to reboot into recovery mode. When I try to do this the recovery console says e: can't open/cache/recovery/command and I can't connect to my phone. Any help?
To start I want to say Thank you to the OP for posting this. But there are a few errors, so I hope I can help.
To anyone having issues with this, there are a few things that you must have to make this work.
Note this only works for AT&T Atrix as I do not have a Bell Atrix
#1; THE 1st PART DOES NOT WORK if you performed the update. You should be rooted. You can check to see if you updated by pressing menu --> settings --> about phone and your Build version says something like OLYFR_U4_1.5.7 it will not work, you need to skip down to my next post of my coding since you should already be rooted. The 1st part of this uses the method that made rooting possible, since that was removed with the update, it no longer applies. So if you are updated, you should already be rooted and can skip a few steps
#2; You must have a folder called WebTopModBackup with the .bak files in it on the internal memory (not your memory card but the fake internal one). Open the app called Files, select Internal phone storage, select the WebTopModBackup folder and make sure you see the following files, if not you need to get them
Code:
DockProvider.apk.bak
DockProvider.odex.bak
DockService.apk.bak
DockService.odex.bak
PortalApp.apk.bak
PortalApp.odex.bak
#3; Do not mount your sdcard. When you plug in your USB cable to the compter, pull down the drop menu, select the USB connection and make sure None is selected; then press ok. If one of the other options are selected, select None press ok and wait for 30 seconds for the internal and external cards to mount. @Phazoni more than likely this is your issue
#4; USB debugging must be turned on. Press menu --> settings --> applications --> development --> and check USB debugging if not checked
#5; Make sure you have at least 50% battery, just in case
#6; During the steps you mount (make it editable) the /system folder where the files are, if you get a read-only error you did not do step
mount -o rw,remount /dev/block/mmcblk0p12 /system
correctly or your phone is somehow not rooted.

Ok now let's look at the code in the OP
Code:
adb.exe push psneuter /data/local/tmp
adb.exe shell chmod 755 /data/local/tmp/psneuter
adb.exe shell ./data/local/tmp/psneuter
adb.exe shell
adb.exe push is the command to copy a file to your phone; so we are making a copy of psneuter and putting it on the phone.
adb.exe shell chmod 755 this gives premission to the phone to use the psneuter file
adb.exe shell ./ this makes the psneuter file run and creates a fake root
adb.exe shell this should really be typed as adb shell but whatever. This takes you into the phone's system to edit the files. While in adb, the line should start with a # if it is a $ then psneuter did not work. Just to try, type su and see if the $ changes to a # if it does continue
Code:
cd /mnt/sdcard/WebtopModBackup
This command takes you to the location of your backup, remeber step 2 & 3, if this folder is empty and you cannot get to it, you have an issue there
Code:
mv DockProvider.apk.bak DockProvider.apk
mv DockProvider.odex.bak DockProvider.odex
mv DockService.apk.bak DockService.apk
mv DockService.odex.bak DockService.odex
mv PortalApp.apk.bak PortalApp.apk
mv PortalApp.odex.bak PortalApp.odex
Personally this is not the best way to do this (rename the files by making copies and then making more copies), but not my code. The mv command moves a file. In this case you are only using it to rename the files removing the .bak from the end. See my code at the bottom
Code:
mount -o rw,remount /dev/block/mmcblk0p12 /system
This mounts the /system folder so you can edit the system files
Code:
cp DockProvider.apk /system/app/
cp DockProvider.odex /system/app/
cp DockService.apk /system/app/
cp DockService.odex /system/app/
cp PortalApp.apk /system/app/
cp PortalApp.odex /system/app/
This code copies the files into the original locations as the correct name. This assumes you are still in the folder where the backups are. If this fails, the /system folder is not mounted, the files are missing or you are in a different folder. This is also missing the chmod /system/app/* coding. I will cover that below
Code:
rm /data/dalvik-cache/[email protected]*.dex
rm /data/dalvik-cache/[email protected]*.dex
rm /data/dalvik-cache/[email protected]*.odex
rm /data/dalvik-cache/[email protected]*.odex
rm is the command to remove/delete a file, running these 4 commands will remove the system cache and will most likely cause your phone to reboot before the next step; that is ok.
Code:
reboot now
This reboots the phone and removes the temp root.

NOW for my recommended coding
After you follow my 6 steps above do the following
#1. on your compter press start --> run --> Type cmd this will open the command prompt for windows. Then navigate to the folder where the original WebTopMod files are located.
#2a. If are rooted jump down to step 4
#2. If you are not rooted and have not updated your phone type the following letter for letter
Code:
adb push psneuter /data/local/tmp
adb shell
You will now be in the ADB shell.
#3. You should see a $ so type the following
Code:
chmod 755 /data/local/tmp/psneuter
./data/local/tmp/psneuter
#4 This will kick you out of ADB, wait for it and when it does count to 30 for adb to reset. Now type the following:
Code:
adb shell
#5. You should see the # sign, if you see $ type su to change it since you should be rooted either by rooting the phone or using steps 1-3 above for pre-update.
Code:
mount -o rw,remount /dev/block/mmcblk0p12 /system
cp /mnt/sdcard/WebtopModBackupDockProvider.apk.bak /system/app/DockProvider.apk
cp /mnt/sdcard/WebtopModBackupDockProvider.odex.bak /system/app/DockProvider.odex
cp /mnt/sdcard/WebtopModBackupDockService.apk.bak /system/app/DockService.apk
cp /mnt/sdcard/WebtopModBackupDockService.odex.bak /system/app/DockService.odex
cp /mnt/sdcard/WebtopModBackupPortalApp.apk.bak /system/app/PortalApp.apk
cp /mnt/sdcard/WebtopModBackupPortalApp.odex.bak /system/app/PortalApp.odex
chmod 644 /system/app/*
rm /data/dalvik-cache/[email protected]*.dex
rm /data/dalvik-cache/[email protected]*.dex
rm /data/dalvik-cache/[email protected]*.odex
rm /data/dalvik-cache/[email protected]*.odex
reboot now
This
1. mounts the /system folder so you can replace the files then
2. renames nd copies the back-up files to the original locations in one step
3. Then the chmod 644 command sets the correct premissions for the files so they work,
4. clears the cache and
5. reboots the phone.
