[Samsung Epic 4G Touch] kobridge:
Kobridge's Stock Bloatware Remover for Jelly Bean

Some useful info on JB ROM:

Some widgets are not working on JB depending on the launcher.

Samsung Task manager is not showing from app list. To launcher the app, you can use the widget or long pressed 'home' button to run the Samsung task manager.

Old sqlite3 binary does not work on JB. I had to change the sqlite3 binary in this rom to make the wifi sleep timer working.

It appears that external_SD under /SDCARD is no longer pointing to external SD card. Now it's under /mnt/extSdCard, /storage/extSdCard - I need to look at some scripts running during the boot.

System partition is too small to hold all apps. It seems like that's the reason why Samsung added /preload partition and moved some of non-core apps there. I tried to keep all apps into /system partition and phone didn't boot.

snapshot key - vol down + power do not work any more. To get the snapshot, press the home key + power button together

New way to recover the phone using Nandroid & stock ROM:

Because Jelly Bean is using another partition which is not covered by our traditional CWM recovery. Whenever you restore your phone using nandroid backup oly, you may not get the full restore of your phone. It's because the /preload changes are not included. So, there is no way to backup this folder by cwm recovery.

So, what I'm suggesting method is

1. Be sure that you have a nandroid backup after JB rom flashed. Be sure that you have the flashable JB rom.

2. now to start the nandaroid recovery, reboot into cwm.

3. (full wipe data & cache) or do the factory reset

4. flash JB rom

5. (do not reboot after flashing the ROM) recover nandroid backup on the same recovery session

6. Flash Kobridge's Bloatware remover tool if you did that before

7. flash the JB kernel again (if your CWM kernel during nandroid backup was ICS or lower, then phone won't boot without this step)

8. reboot

Some other Kobridge's Tweaked ROM info:

When many apk files are updated or if you flashed new Kobridge's stock ROM, remove /data/local/zipalignedapk file and reboot. It will try to re-zipalign all apks from /preload /system/app /data/app.

Removed apks are placed in /storage/extSdCard/Removed_Apps/ (from system/app) and /storage/extSdCard/Removed_Apps/preload (from preload/symlink/system/app). /storage/extSdCard folder is a symbolic link of /mnt/extSdCard.

To move the removed apps back to original folder, you have to copy(move) the apk files from Removed_Apps folders to /system/app folder and change the permision to 644 and reboot. You cannot move the apk files back to /preload folder because the symbolic link is not there. To move it to preload folder, you have to manually create the symlink for the move files.

If you do not want to use Kobridge Tweak, remove the init.d folder and /system/bin/dvfs.sh file. For build.prop, copy it from original stock rom and place it to /system folder.

To check the tweak result, find /data/log/kobridge_tweakxx.log files (total 4 files created)

Again, I do not use 'data wipe'. From ICS to JB, everything moved ok and working fine for me.

On the same CWM recovery session, you can flash the ROM, Modem, and bloatware remover script also. But be sure that you need to wait enough time until system reboot and settle. After flashing the ROM, you may need to wait about upto 5 minutes. If you removed alignedapk file and doing the re-zipalign, then it would also take 3-5 minutes.

How to flash - just like flashing the rom, flash zip file from CWM recovery.

You can flash this zip file just after flashing the rom or you can flash this zip file separately depending on your need. Be sure that after you flash this zip file, you may need to flash the original Kernel also at the same CWM session without rebooting your phone.

Where you can find the removed apps

You can find the removed apps from /mnt/extSdCard/Removed_Apps (system apps) and /mnt/extSdCard/Removed_Apps/preload (preload apps). To bring it back to your phone, move the apk files to /system/app or /preload/symlink/system/app folder and reboot.
