Well that cwm is simple and the function in it is a bit wierd.

I did try to get z4mod creator to make it better but no luck.

Also its good to use titanium backup.

[Galaxy S I9000 Android Development] richyy74:
I am using titanium.

Its not connected to your kernel, but you know much better than I so I ask:

I also noticed that after every boot I have android minimal 1.16.2 busybox no matter how many times and where I install 1.17.1. There is busybox in /Z4mod/bin and /system/bin which seems to be identical but in /Sbin busybox seems to be a link to recovery which if I understand it right is smaller and older. However If I install busybox to /Sbin I got version 1.17.1 until next boot, than all is back to link again.

If you could make some explanation or point me to right direction I would be grateful.

Thanks
[Galaxy S I9000 Android Development] DamianGto:
Yes thats true. I will update the busybox to the latest as soon i get all my developer stuff up.

You can try to install the latest busybox to /system/xbin to se if that solve it for now.

Hello Damian!

It's possible to make a kernel with all the tweaks like this version DamianGTP_JPX_300HZ_3A but with HZ=500? I would appreciate very much.

I just tried Speedmod kernel and I think yours is better.
[Galaxy S I9000 Android Development] DamianGto:
Hi.

I will do an update and make a 500HZ version.

It will also has some more tweaks.

The base will be the same that i use with the steam kernel.

basically they are the same with different recovery system.

Hey Damian,

z4mod won't work on 2.2.1 ROMs right? If so maybe you can mention it in the first post & the Title.
[Galaxy S I9000 Android Development] DamianGto:
It works.

Its z4Root that dont work on 2.2.1.

The only problem with this kernel is the lack of a working cwm so you can flash themes.

I hope z4ziggy and ryanza come back and continue to develop this.

It working now, but when 2.3 comes out it will maby not.

But i do have steam kernel also so my kernel will continue to be developed.

I can also use hardcores initramfs if i still want 2 different kernels.
[Galaxy S I9000 Android Development] DamianGto:
**** UPDATE **** UPDATE ****

It was some time ago I did update this kernel.

The main reason is that the developer of z4mod(Z4ziggy and RyanZA) has stop working on z4mod and they are also not on xda anymore.:(

So i had to decide what to do with z4mod.

There is some issues in the recovery and thats needs to be fixed.

The problem is that without z4ziggy developing z4mod will make it to old soon to work with and I cant rewrite it either.

So without any future development of z4mod i cant use it anymore and its a wast of my time to keep trying to keep this kernel alive.

But if you like my work you can always use one om my other kernel.

The steam kernel is my big project and the most advanced kernel. You can read and get it here:)

I also working on a new kernel thats more simple recovery in.

That kernel should be a direct improvement over this kernel and its faster and smoother. :o

I will post more information as soon this kernel is ready.

I hope you all understand my view on this issue.

One thing though, to upgrade would I have to revert back to the stock rfs one then flash it with a new kernel?
[Galaxy S I9000 Android Development] DamianGto:
Good;-)

If the kernel is different it would be wize to revert back. But many times you can just flash if the kernel is from the same place.

Can you start the recovery?

Where do you put the update.zip file?

Hi,

I've installed z4mod and currently using ext2 filesystem. Can I just flash this kernel without reverting back to rfs (or without wiping my data)?

Thanks
[Galaxy S I9000 Android Development] DamianGto:
This is a kernel with z4mod so it should work. It depending on what kernel you did use in the first place.

You should always do a backup before you flash anything. Just in case something unexpected happens.

[Galaxy S I9000 Android Development] GantengX:
I just installed your kernel and seems to work fine without any problem.

Going to check how's the battery life under this kernel, because I noticed that after using z4mod ext2 my battery drains quicker than normal OCLF.. Today it drains 3% within 1/2 hour (I disabled packet data) which is quite weird.

Hopefully the battery would last longer in this kernel ;)
[Galaxy S I9000 Android Development] DamianGto:
I can't say how the battery drain is, but it should not be so different from stock.

Im a heavy user and i use the gps often and then it always charge in the car. I also have Wifi all the time on when Im home.

So it would be fun to know if the battery drain has changed from stock kernel.

[Galaxy S I9000 Android Development] GantengX:
Hopefully the battery would last me 2 days :D

Btw currently my phone is on GSM mode and I disabled the packet data, then I checked my battery using *#*#4636#*#* and the battery stats as below:

voltage: 4132mV

temp: 29-30c (phone is not used), if I use it to play game it's about 39-44c

Is the voltage and the temperature a bit high? I remember using eclair my voltage about 3800ish and even if I play games the temperature at most stays at 38-39..

Do you know anything about this? Thanks :)
[Galaxy S I9000 Android Development] DamianGto:
Its normal.

The voltage is about what you have when its good and almost full.

Not to sure what happened damian but i flashed your kernal on odin, was on speedmod k7 before and then i had an error with the file system and now when flashing i'm getting that annoying stl11 error E:can't mount /dev/block/stl11.

Anybody help with this? I can't seem to get anything running with 803.pit
[Galaxy S I9000 Android Development] DamianGto:
That's the cache partition that is basically broken or different filesystem on.

So you need to restore that.

If you flash back the speedmode kernel and go to recovery you could restore the cache partition to original. Then flash this kernel.

I never try that.

You should never flash a kernel with different system.without restore to the phone original settings.

So if i want to try this z4mod out do you suggest that maybe it is better if i don't install speedmod at all.. i mean i'm on stock JPO right now and will either install fresh doc's rom or restore from cwm to my last good backup.

If fresh rom could i just repack your kernal (zImage-think) into his rom then flash it? or do you think there would be conflicts?

Or if i restore and go back to speedmod, what is the safest way (if any) to switch to yours?

btw thx for the help :-)
[Galaxy S I9000 Android Development] DamianGto:
If you on stock firmware now and it works then you can flash my kernel without any problem.

Then apply the update script to converting to ext2 filesystem.

Try it out to se if you like it.

If you don't want it then just use rts script to change back to original filesystem. Then you can flash what kernel you want.

Can take quite a while! Probably something like 30 seconds per 100mb of data. It's hard to say, as it depends on number of files as well as file size. (It's making a .tar out of all your data, and then it will restore it.)

Also z4mod will not allow me to convert my fs back to rfs to test if that is causing the issue.

It says Error: /data/data/com.z4mod/files/z4mod (Permission Denied)

I flashed 300hz kernel on a fresh XXJPO and now I can't mount /sdcard on CWM. It keeps giving me this error message:

Do you know anything about this? I have been reflashing my phone just to try get rid of this problem. But sdcard is mountable once the phone is booted up (not on recovery)

I used z4mod to change my filesystem to ext2. Could this be the reason? :confused:

[Galaxy S I9000 Android Development] Sociopathic:
I am really, really sorry about the stupid question but I'm still not sure how to install this.

I have OCLF installed already. So first I'll have to remove the lagfix. As far as I understand it's OK to leave the phone rooted.

Then I'll have to flash with ODIN the desired kernel - in my case it's zImage_z4mod_12_1_v1_500hz.zip. So far so good but I'm not sure which one of the files is the one I should rename to update.zip.

And what exactly I am supposed to do with z4mod.0.9.apk.

If anyone can provide me with some clarification that will be great :)
[Galaxy S I9000 Android Development] DamianGto:
If you flash that kernel then it should work fine.

You don't need to use any update.zip script. You use the Z4mod app to change the filesystem.

Its more easy then before:-)

[Galaxy S I9000 Android Development] DamianGto:
How long time it takes depending on how much apps you have.

The phone was running JPO and rooted with CF-root. I had OCLF installed. As I said before I removed Lagfix 2.2+ and removed ExtTools through the OCLF app. Flashed with zImage_z4mod_12_1_v1_500hz.tar and than tried to convert to EXT2 with z4mod.0.9.apk. Hope this helps.
[Galaxy S I9000 Android Development] DamianGto:
Well flashing can be a risk to loose data. That's why you always should have a backup.

Don't use cf-root kernel. Its a bad way to root and you loose it when flashing other kernels. I guess this was happened for you.

Use Z4root.

Do flash jpo firmware and see that all things work.

Then flash this kernel.

Restart the phone and se that it works.

Then clear you memory( level 2) and then use z4root.

Restart the phone and then start the z4root again and you will se if its rooted.

If its okay then use z4mod to convert to ext2.

Do clean your memory again before you use it.

That's for making sure there is not any program that interfere with the Z4mod.
