Epic CM Team Blog: Boot FC09 from SDCard

Useful Utility for CM9 Epic 4G
This is a temporary ROM that boots Samsung's FC09 firmware entirely from sdcard without making any changes to the ROM installed on your phone. Simply reboot to return to your normal ROM. This sdcard ROM is useful for several purposes.
  • Settings > About Phone > System updates >
  • Update Profile.
  • Update PRL.
  • Settings > Display > Horizontal calibration
  • Do this if you have problems with auto rotate on CM9.
  • Sprint Activation.
  • Dial codes and diagnostic mode.
  • Test Samsung FC09 behavior to aid in CM development.
Changelog
  • FC09-based with working 3G, 4G, Update Profile, faster speed.
  • Uses 500MB on sdcard instead of 1GB.
  • Includes Connectbot and GPS Status.

  • Test stuff on EL30 to compare behavior to aid in CM debugging.
  • Update Profile, PRL, or do Sprint Hands Free activation.

samsung-epic-stock-el30-kexec-multiboot.tar.bz2

171MB md5sum c4532cd10b37382d25af8304deb57fe8

How To Procedure
  1. Download the tarball.
  2. Unpack it in sdcard, leave the directory structure intact.
  3. Boot into CWM.
  4. "Flash" multiboot/EL30/boot_EL30.zip
  5. It will boot EL30.
Warnings!
  • DO NOT MOUNT USB STORAGE. BAD THINGS WILL HAPPEN.
  • NOT RECOMMENDED FOR PRODUCTION USE.
  • It will be a bit slow because your sdcard is slow.

Could someone do a video for this looks pretty nice but I don't understand how or what a tarball is anyways haha

Lol, I was just suggesting this idea for PRL updates a few hours before this thread was created, didn't think I'd see it manifest so soon (not trying to claim credit, just enjoying the coincidence).
