Anyone who is using my kernel should upgrade to the Kouma Kernel

http://androidforums.com/galaxy-prevail-all-things-root/429740-koumakernel-0-1-beta.html

I have not had the time to make an updated kernel, so Kouma was kind enough to do it





-----------------------------------------------------------------------------------------


I created a Kernel and updated ClockWorkMod Recovery V4.0.1.5 for Samsung Prevail SPHM820

Using Odin or ClockWorkMod can be dangerous to your phone, make sure you know what your doing, make sure you have a charged battery or plugged into power.

Please also read second post


If you have taken the EE14 official update you need to remove /system/etc/install-recovery.sh
If you do not remove this file the stock recovery gets flashed back when phone is rebooted
I made a zip file that will do this for you, it needs to be flashed from CWM as soon as CWM is installed, so you have to go into CWM as soon as Odin resets the phone, with out letting the phone boot up, a link to the fix is below


DOWNLOAD HROARKERNEL 1.2 and CWM
1. Download and unzip the file.
2. Download EE14 Fix stick.zip and copy to sdcard (if you need it)
3. Install the Samsung USB drivers (if you don't already have them)
4. Put phone in Download Mode by holding Vol down, Camera Button, and Power button until the Yellow Downloading message appears
5. Plug phone into USB port
6. Open Odin, you should see a yellow box with a com number
7. Select SPHM820.ops in the OPS box
8. Put a check in One Package
9. Select the tar file in the One Package box
10. Click Start
11. When Odin says reset and the phone reboots Hold Vol UP, and Power button until you are in CWM DO THIS QUICKLY BEFORE PHONE BOOTS, IF PHONE BOOTS UP ALL THE WAY START BACK AT STEP 4. you do not have to wait for Odin to say pass, that does not work
12. In CWM go into install zip from sdcard
13. select choose zip from sdcard
14. select stick.zip
15. select Yes - Install stick.zip
16. After it is done installing Press back button
17. Select Reboot System Now

Please see my other thread about the functions of ClockWorkMod
http://androidforums.com/galaxy-pre...ecovery-v4-0-1-4-samsung-prevail-sphm820.html

This ClockWorkMod has been updated to support EXT4 file system


Hroarkernel adds support for EXT4 files system, and Init.D support

I did test the EXT4 file system access with adb and link2sd and it works fine, my ext4 sd-ext partition was created and formated in CWM

If you are using my kernel you should format the sd-ext partition you create it in CWM so that it gets changed from ext2 to ext4, you format it in the mounts and storage menu in CWM

ALWAYS BACK UP YOU SDCARD BEFOR YOU TRY TO PARTITION IT


I am not sure how to test Init.d, but it should work, I will need some people to test this for me and let me know if it works


This kernel does not support Overclocking, and anyone who asks if it does will not receive a response.

Please keep this thread on topic, I do not support other apps that you are trying to use

Suitable subject are the kernel, cwm, ext4, init.d, and link2sd

This is not a compiled kernel, I can not do that because the Samsung source code is broken

The changes made in this kernel reside in the ramdisk portion of the boot.img,
I added the ext4.ko, jbd2.ko, initd_support.sh and modified the init.rc file

The main kernel file "zImage" is unchanged

Ext4 file system support will help future development, and will resolve some of the issues people are having with the link2sd app when you are trying to use an sd partition you made in CWM
 
Nice release. It's good to see more development. Nothing against shabby it's just good to see others releasing as well. Odin, cwm and now a kernel. Nice work hroark.

One other thing that you you should mention behind the over clocking point is that it also does not support the official flash before you get that question spammed a billion times as well.

do you mean flash player?
 
Necrotoxin said:
Yes. I know the modified version would still work but the official flash from adobe won't unless I'm mistaken.

I am not to sure, from a system standpoint, this kernel looks exactly like stock, the only difference is the modules that load, and the script that runs

So what ever issues people were having with flash player will still be there

Yeah that's what I thought. I was only bringing up the point to stop the questions about whether it will our will not work so it doesn't have to be answered a billion times :p

i put a little note in the second post about suitable topic, thanks for the advice
 
Please pardon my noobness but does this mean we can use cwm to ceeate ext 2 sd ? Or should I use a program on my pc ? also once installed will it show more memory on my internal section ?

yes you can use cwm to partition sd, i dont think it will show more memory, but you can use link2sd to move apps to that partition

when you create a partition in cwm it creates it as ext2

but once the partition is created if you format the partition or do a factory wipe in cwm it changes that partition to ext4

i figured out how to change this behavior, but figured it would just be better if we had a kernel that supported ext4

if the ext4 support does not work out, I will make a cwm that just leaves the partition at ext2

the stock kernel supports ext2
 
what's the difference in ext2 and ext4?
i made ext2 partition using a program on the computer. and the link2sd worked fine.
will this kernel still be necessary? i only need it if i wanted to create the partition using cwm correct?

if you are using a ext2 partition on sdcard, dont use cwm to format it and dont do a factory wipe in cwm, because that formats it too

when it it is formated on cwm it is changes to ext4

which your current kernel does not support

that is main reason i made this kernel for ext4 support

i thought CWM formatted the partition to ext3??

wasn't that the reason we were hoping for some ext3 support in the upcoming mods (or kernals)?

I think in that post I said it was either ext3 or ext4

I turns out it is ext4

I can make a new CWM that leaves it at ext2

But I want to give the ext4 a chance first to see how it works out

1. i'm still using the previous version of CWM which does format to ext3 hence the confusion

2. the only reason i use ext2 is because it's the only thing link2sd (running on shabby 0.9) works with, i'm not suggesting that you should make a ext2 version of CWM, though i was completely unaware that you could change it?!? that is good info to know, but until i've had some time to test the new kernals and see what difference it makes to a possible sd-ext Vs. link2sd conflict, and furthermore which one if not both is better, than i'd suggest you just stick with #3 (below)

3. ext4 (according to shabby) sounds like a good place to start

no it does not, trust me, i know these things

i was not sure before, but I know for sure now

when the partition is first created in CWM it is ext2

if you factory wipe or format it goes to ext4

This is the same in both versions of my CWM

But with this new kernel a module loads that allows ext4 access when you go in to CWM or load the Android OS

The stock kernel has built in support for ext2 so no module is needed

We would not need an ext4 module if we could compile samsung source code, but we can not because it is broke

So we have to load a module for ext4 support

I am not gonna add ext3 support, there is no need for it.

If the ext4 does not work out well, I will release a version of CWM that leaves the sd-ext at ext2 when you factory wipe and format

Can you make a EE14 Rooted recovery with your kernal?
Click to expand...

for now people could just flash this after they flash EE14 rooted Odin

I know it is an extra step

I want this to be out there for a while and be tested before I do that

It may not work good, or I may add some features to the kernel

I would also like to make a ROM that is completely ext4
 
Thanks Hroark for this new kernel, it's amazing that in just a few months the Prevail is having custom kernels and roms. I am going to flash this new kernel, but I have a question. I know this kernel supports link2sd but does it support something like Darktremor apps2sd since it supports init.d? If it does I am willing to try it out. Thanks for all your hard work.
