[ROM][CM9][AOKP] Temporary Stock E4GT from emmc

Epic Touch Blog: Temporary Stock E4GT from emmc

Utility for CM9 Epic Touch
This is a temporary ROM that boots Samsung's Gingerbread EL29 firmware entirely from emmc without making any changes to the ROM currently installed on your phone. When you reboot, you return to recovery where you can re-flash the ROM to return to CM9. This temporary ROM is useful for several purposes.

Update Profile.
Update PRL.
Sprint Activation.
Dial codes and diagnostic mode.

This should be helpful to users of any AOSP-based ROM including CM9, AOKP, etc.

Thanks to noobnl and mkasick for making this possible!

Would this work to flash .zip updates (such as kobridge) or updated ROMs (such as alpha5)?

This definitely will come in handy, can I suggest seeing if you can get a video made of how it works. I can honestly say It seems to help out quite a bit in this forum for a lot of people and does cut down on the crazy questions.

Great job though!

You can use the directbootCWM file to update CM9 yes. Not sure about using it for Kobridge tweaks.

Maybe qbking can make one for those who need it.

Its for AOSP roms. You currently can't update PRL/Profile, activate your device, or use dialer codes on them so this temporarily allows you to boot stock el29 off the SD card without changing your current rom. You can do what i said from there. Saves you time from doing backups, restoring, etc.

I'm hoping that someone can help me out as I am unable to boot into the temporary ROM. Here are the steps I followed:
1. I have everything extracted to emmc as directed.
2. I flashed directboot CWM utilizing mobile odin which correctly booted me into CWM version 5.0.2.7
3. I flashed boot_EL29.zip at location /emmc/multiboot/EL29 and received the following messages that appear to be correct.

Finding Update Package...

Opening Update Package...

Installing Update...

Boot /emmc/multiboot/EL29/zImage

Create mount symlink.

Remount partitions read-only.

(Re)mount /emmc read-only.

Unpack kexec.

Load zImage and initramfs.

Sync.

Reboot into zImage.

Install from sdcard complete.

4. At this point I expected the phone to reboot into the temporary rom; however, it just shows the standard recovery menu. No reboot occured.
5. Because no automatic reboot occured, I selected "reboot system now" from CWM. Unfortunately this just brings me back into directboot CWM.

Thanks in advance for any help provided.

I am having the same problem I thought it could have been the downloading or unpacking so I downloaded it again and unpacked it and still have the same problem.

I what having this same issue. There is a different version of direct boot, v3 that you have to use for this.

All I see is v1 up on the e4gtcm site. Where did you obtain v3 from?

poormansupra · May 31, 2012

Worked with V3 direct boot Thanks

This sounds pretty cool and I would like to test it... what I don't understand is when I'm done with the temp rom, how do I get back to AOKP? Do I need to reflash the whole AOKP rom? Just the kernel?

When done updating prl/profile, etc. Just reboot your phone and it will take you back to cwm recovery. From there you can either just reflash the rom or just a compatible kernel so it boots.
