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.

Since a lot of people have been asking, I set up a paypal account and got a donate link:
Feel free to donate if you want, but I'm happy if you don't donate too.

Damn! Just when I decided to try out the stock firmware without any lagfixes. :-| Guess I have no choice but to succumb to your awesomeness now.

Will make a backup of data on my internal memory (just in case) and give this a shot on my brand new JM8 now :)

Hang on, looks like it has a bug! I did a clean firmware flash, and its just giving a 'disabled' message, because it seems to be erroring on trying to find /dbdata/ext2data/

I'll have a 2.0.1 up within a few minutes with the fix. Sorry! I need a QA department!

Good work!

Do we need to uninstall APK v1 before using this APK?
I guess yes, but you never know.

Is this the app version of "voodoo" fix only with ext2 (the one you started testing earlier in different topic) or its old virtual file method?
