Help please...

I installed OCLF 2.3.0 and everything was awesome. Then I installed Absolute system root tool. This app gave me problems so I uninstalled it and tried to fix the damage by doing a factory reset of my samsung tab 7" wifi only P1010 (rooted froyo2.2.) Once the problem was fixed I lost all the features of OCLF. I tried uninstalling and reinstallinf EXT2 and when that didn't work I uninstalled the app completely and reinstalled it. This didn't work either. when I click on the install / uninstall buttons for V 2+ (which are both highlighted red) I get conflicting replies. Clicking the install button gets me "youalready appear to have another lag fix installed! (system/bin/playlogo less than 5kb)." When I click the undo button I get " you do not appear to have a V2 lagfix installed!(free space on /data does not match /dbdata/ext2data). What can I do to fix this and get OCLF working right again?

By the way, The work you people do here is awesome and much appreciated. thank you for what you do.

any help would be greatly appreciated.

Thank you.

One Click Lag Fix on GT-S7562 - HELP!!!!


I'm absolutely new in manipulating Android. I have a GT-S7562 and it's quite slow. I read a lot of posts regarding speed it up.

What I've done:
1. As a first step I rooted it with the help of this (http://forum.xda-developers.com/showthread.php?t=2171441)

2. Installed the One Click Lag Fix. Here I've been unable to select the fix in any way. I always get a message : missing playlogos in /system/bin/ folder.

I have no glue how to go on :(

I have Android 4.0.4 on my phone.

    OneClickLagFixV2PLUS inside the app is currently in RELEASE status. It has been tested on a fairly enormous number of devices without issue.

    This is an APK (Normal Android App) that will install an EXT2 lag fix for you.

    The APK itself can support a number of different lag fixes. It currently has the old OCLF V1 fix, which uses symlinks, and it now also has a new V2 fix which uses bind mounts.

    This is in a new thead, as the old thread is very very long, and this is now version 2.

    New features of the OCLF2+ lagfix vs OCLF1+

    - Bind mounts are faster and require less O/S overhead than symlinks, making this fix smoother in everyday use.
    - The bind mount allows for Android to report the correct free space available.
    - If something goes wrong at boot, and the bind mount does not initialize, you will boot up to a copy of your data from before the lagfix was applied. This makes V2 safer than V1. (copying /system/bin/playlogosnow onto /system/bin/playlogos1 will effectively restore your device to how it was before you applied the lagfix. There is also an undo option, which will copy all of your changed data back to RFS before restoring.)

    - As a bonus, an option to set the wifi screen off timeout is included.

    How to use this:

    Copy over the APK file onto your phone, and run/install it as normal using 'My Files'. There will be a 'One Click Lag Fix' app installed. Run that, and select the option you want!

    The app will automatically kill all running tasks, and enable flight mode. You should probably not use the device while the lag fix is running. If you accidentally hit back or home by mistake, re-enter the app and re-select the lag fix. It should still be running.

    Known issues in 2.0.0

    Some devices with heavy carrier customization cannot install EXT2 Tools. Fix should be in the next version, if possible.

    On Froyo (Android 2.2) this lag fix will refuse to install if the apps2sd feature is in use. The error you will see if Apps2SD is in use on installation will be that the loopback cannot be mounted.
    Workaround: In order to install the lagfix on froyo, you will need to set each app that is on the external SD back to regular. Once the lagfix is installed, you can move apps back to the SD.
    Fix should be included in the next version, if possible.

    If you use up more space inside the EXT2 than is available outside the EXT2, you will have to remove apps/delete data until you have enough space to copy your data back when you want to uninstall. To help avoid this, don't set the space bar all the way on the far right.

    Rooting Froyo

    Froyo's recovery mode is locked down, so you can't root it from your device.
    However, you can use this: http://forum.xda-developers.com/showthread.php?t=803682


    Since a lot of people have been asking, I set up a paypal account and got a donate link: https://www.paypal.com/cgi-bin/webs...=PP-DonationsBF:btn_donateCC_LG.gif:NonHosted
    Feel free to donate if you want, but I'm happy if you don't donate too. :)
    Just wondering, does anyone have a solution to this?
    I have a galaxy using froyo and rooted with SuperOneClickv1.5.5-ShortFuse.

    Issues with options not being available resolved by rebooting the phone (turning it off and on for that one person who posted how do do that :) ).

    Resolved this issue: "When I try to install OCLF2.2+, it failed on moving the playlogos1 file." by doing the following.

    Used Autokiller memory optimizer from the market (the processes and services tab) to kill all processes and services other then system proesses (apps I had installed) and voila....installed OCLF.
    Full source code under the GPL is available from http://code.google.com/p/oclf/
    Nice work! Will test it soon!
