[Verizon Droid Charge] jco23:
For rooted Charge owners, some are on the RFS file system, others are on EXT4. The Charge comes as RFS stock, so unless you have converted to EXT4, chances are that your phone is still on RFS. What's the difference? Click on this link to view a discussion among some of the original developers including IMNUTS: RFS to EXT4 - Page 3 - xda-developers

Keep in mind that nobody except YOU are responsible for what happens to your phone. Past performance is no guarantee of future results, always read the instructions carefully before flashing, feel free to ask questions.

Note: the kernels mentioned below are for FP1 & FP5 ROMs - currently, there are only two ROMs with this build, Eclipse and Tweaked

FP5 build is currently only supported by the Tweaked ROM - thanks to kynalvarus for developing the FP5 custom kernel!

Before you begin the conversion:

- make sure that you have root access and can enter the Clockwork Recovery Mod (CWM)

- download and install Terminal Emulator from the market

- once in there, type "SU" then "Mount" (without quotes)

- scroll to the top and look for the text after the following folder names: "/system", "/data", "/dbdata", and "/cache"

- if you see RFS, then you are on RFS, if EXT4, then you are on EXT4

- download Imoseyon's kernel (http://rootzwiki.com/topic/3426-kernel-gb-imoseyon-kernel-stock-repacked-v400-11611/)

- make sure that you've got plenty of battery life on your phone (or plug it in during the process), for me, the process cost me ~5-10% of battery life, but your experience may vary

below are the steps to convert RFS to EXT4:

check to see if you have a folder called "sdcard/VooDoo/disable-lagfix; if so, then delete it, if not proceed to next step

1. boot into CWM

2. mount system

3. install zip from SDcard

4. select Imoseyon's kernel

5. re-boot system (process can take about 10 minutes, you'll hear a robot lady voice telling you that the system is partitioning, and will give you an estimated time of completion)

6. check to ensure that the conversion took place by entering into Terminal Emulator and looking for EXT4; if still RFS, then:

a. Download and install voodoo control from market

b. Check all ext4 boxes then reboot

c. Re-check with Terminal Emulator

7. boot back into CWM

8. mount system

9. install zip from SDCard

10. select your flavor of PBJ kernel (note: stock FP1/FP5 will NOT work on EXT4)

a. FP1: tonsit

b. FP1: 0502 PBJ (no longer posted, ask a member of this community for the file)

c. FP1: 0504 PBJ (no longer posted, ask a member of this community for the file)

d. FP1: 0524 PBJ

e. FP5: Lazarus Recharged

11. be sure to "Fix Permissions" in CWM before rebooting or you could lose root (if you still lost root, then simply flash SuperUser/SuperSU via CWM)

below are the steps to convert from EXT4 to RFS:

1. check to see if you have a folder called "sdcard/VooDoo/disable-lagfix" (without quotes); if not, then create it; if so, proceed to next step

2. if you have a custom boot animation, change it to read "sanim.zip.bak"

3. boot into CWM

4. mount system

5 .install zip from SDcard

6. select Imoseyon's kernel

7. re-boot system (process can take about 15 minutes, you'll hear a robot lady voice telling you that the system is partitioning, and will give you an estimated time of completion)

8. check to ensure that the conversion took place by entering into Terminal Emulator and looking for RFS, if still EXT4, then:

a. Download and install voodoo control from market

b. Un-Check all ext4 boxes then reboot

c. Re-check with Terminal Emulator

9. boot back into CWM

10. mount system

11. install zip from SDCard

12. select your kernel

a. Stock FP1

IMPORTANT: you can only convert to a stock kernel from another stock kernel or the 0524 PBJ kernel (presumably the Lazarus kernel as well). For example, if you are on the 0504 PBJ kernel and want to go to stock FP1, you will need to flash the 0524 PBJ kernel first, and then flash the stock FP1. IMNUTS setup this kernel to help prevent issues when folks wanted to flash back to a stock kernel

b. FP1: tonsit

c. FP1: 0502 PBJ (no longer posted, ask a member of this community for the file)

d. FP1: 0504 PBJ (no longer posted, ask a member of this community for the file)

e. FP1: 0524 PBJ

f. FP5: Lazarus Recharged

g. Stock FP5

be sure to "Fix Permissions" in CWM before rebooting or you could lose root (if you still lost root, then simply flash SuperUser/SuperSu via CWM)
