Hi all

Whipped this up for a friend. Thought we'd be nice and share

These packages will work on any current sw version for the Charge.

Please find below kernel and recovery packages hacked for the following:

permanent adb root
installs Superuser and su binary automatically on boot
includes Voodoo ext4 lagfix - CREDIT TO SUPERCURIO!
lowmemorykiller tweaks
sdcard readahead cache speed tweak

If you are using Odin to flash, simply flash the below package. If you are using Heimdall, remove the zImage file from the below package and flash it.

After flashing the first time, you will hear a voice from the phone telling you what is occurring. The conversion to ext4 will take a few minutes. BE PATIENT. Once it boots, Superuser should be installed, and your phone's filesystem will be converted from rfs to ext4. To disable Voodoo lagfix and convert back to rfs, simply create a file on your sdcard inside the Voodoo folder, named "disable-lagfix". Then reboot your phone and listen for the voices again. This will also take a few minutes.

Please familiarize yourself with using Odin or Heimdall and have backup images on-hand if you are going to use this kernel. If you screw up, you will need them

I DO NOT have a Charge, these files have been tested by other users. As always I assume absolutely NO liability for anything that happens if you use this kernel. Phone blows up? It's on you to fix it

If you find this software helpful please click the "Thanks" or the "Donate" button. Either is fine by me. If you would like to investigate the changes that were made, please feel free to find them here, and here.


Uploaded 2nd version

Uploaded 3rd version
changed the install scripts around
should copy files more efficiently
fix file ownership and permissions

Uploaded 4th version
Confirmed root from independent user!
rewrote install process to preserve file path and permissions
will look into the bootanimation graphics issue

Uploaded additional recovery file
Flashes custom version of ClockworkMod recovery 3.x
Recovery includes Voodoo specific options for enabling/disabling Voodoo lagfix
Flash with Odin or Heimdall just like the kernel files

if you do not have root:
* check adb shell and see if you get a '#' prompt. If so, you *have* root on adb, and you may install whatever you want in /system
* check to see if Superuser app is installed
* check to see if /system/xbin/su exists on your phone.
If you have problems, please post the results of those checks. Thanks.

The kernel flash was successful, and the filesystem conversion took about 8 minutes to run. However, I was not rooted when the phone booted back up. Here is what I did, let me know if I missed a step:
  1. Start on rooted ED1
  2. Accept ED2 OTA
  3. Lose Root
  4. Flash new kernel using ODIN
  5. After ~10 minutes, phone boots successfully, but I do not have root.

Keep trying. I finally got it to flash with 1.30. Seems to be booting. On boot it did not change the file system, it just booted normally.

Edit:I just put in my spare battery and it is now converting the file system. The other battery was probably too low.
