I've set up a initramfs sample for the Epic 4G Touch.

The Epic 4G Touch has a single boot partition, that contains both the recovery and boot kernel and initramfs. This common to many samsung phones.
This kernel build initramfs contains the following features and changes:

• Boot to stock recovery by creating the file /cache/.stock_recovery.
• The recovery ramdisk does not pollute the boot ramdisk. All the ClockworkMod recovery files are in /recovery, and then copied into place during recovery startup.
• Minimal changes to recovery.rc.
• /sbin/recovery is a wrapper script that launches clockwork recovery.

Files of interest:

recovery wrapper script: https://github.com/k...r/sbin/recovery
recovery.rc changes: https://github.com/k...07af8018#diff-1
recovery.bin is the stock recovery binary, and is available if stock recovery is needed.

Thanks Koush, this helps out a lot. Samsung changed the way they did recoveries for their GB builds. Getting ready to do the Samsung Admire CWM this weekend.

Am I supposed to flash the kernel through Odin?

Not odin,

For a zimage, you need fastboot from the android sdk.
you can google the commads.
or go here, if you are comfortable using the cmd prompt

Samsung phones dont use fastboot...

either take the zImage and tar it up and use odin, or put the zImage in a CWM compatible zip file.. you can use one from another kernel, and just change the zImage file..

What would I need to do to get this working on my Samsung Galaxy W I8150. The phone is rooted, and have unlocked bootloader. Could you write some basic steps, please...

Cheers

Koush, vibration is not working on this kernel. Like, at all. Flashed back to Chris41g'slatest kernel and vibration came back. On stock rom.

I fixed this. Please clear your browser cache and redownload the kernel. I forgot to include the kernel modules.

Hi Koush, I just compiled and installed CW to my phone (LG P690 Optimus Net) and it has been submitted to testers in order to verify if it's working or not. I have 2 questions for you:

1) Is there any kind of "checklist" to verify the recovery is working
2) We have no camera button here, so unless we activate the back button (scrolling the menu twice) we can't select the menu options. Is there a way to make it working from beginning?

As soon as we completed the testing phase, I'll submit the recovery to you so you can Add it to your website.

Use BOARD_HAS_NO_SELECT_BUTTON := true and rebuild so you can use power to select.

Test backup and restore, and zip installs.

Thanks Koush, I'll keep you updated

Hey Koush,
I'm working up CWM for the Samsung Admire, in your Epic recovery, where did the recovery.bin come from?

 

[PhantomPhreak53]

Is the epic touch kernel in the op a custom kernel or the stock pulled kernel with CWM added?

This is what it says in the article, you've linked:

"This guide will not work for Samsung phones which use an initramfs."

 

[koush]

Hey Koush,

recovery.bin is the stock recovery binary, just renamed. That's how this kernel supports a boot, stock recovery, and clockworkmod recovery.

Any chance of getting a "How to Port . . . ." for the initramfs devices, the ones with two slots?

Happy to do it myself, given the right tools.

[AnDrOiD69]

Koush any chance you could Pleassse make a recovery for the Samsung Exhibit 4g (SGH-T759).Its a solid phone which has finally been rooted but has no recovery

.I and all other Exhibit uses would be Very Happy if we could have CWM on our phones which will bring us a step closer to getting custom roms so please please help if you can...i know you are a very busy man.

 

[faqali]

I don't know how to port it to my samsung galaxy phone but I think that I have to edit it online on github and then fork it. and prepare an update.zip file and install it from recovery.
please make this clear so that i can continue my work....

 

[klquicksall]

Quick question. I have a Samsung GS2 skyrocket which is similar to the Epic 4g touch. To get this working on the skyrocket do I just place the recovery for the skyrocket into these initramfs? Sorry im still a bit of a noob with samsung kernels.
