sorry guys if I was mistaken, but I read the problem of oclf became laggy during time is the rfs file system, so my question is if I use oclf 1 (oclf 2 didn't work) on top of my z4mod modified kernel (I already converted my filesystem to ext2) will the lag shows up again? thanks guys
[Galaxy S I9000 Themes and Apps] DamianGto:
You don't need to.

You do have ext2 and it won't be laggy over time.

You do have the best already so why try to make it bad?

Hi,

I have an unmodified SGS with the official Froyo 2.2 which I rooted using z4root and installed OCLF. It runs fine 95% of the time but sometimes I experience up to 20 second delays waiting for the home screen to populate with icons and widgets.

I've been recommended to switch to z4mod as a fix to this intermittent lag. My question is do I need to uninstall OCLF first? Is it as straightforward as just clicking "Undo OneClickLagFic V2+" on the OCLF application menu or do I need to remove EXT2 tools and/or unroot the device?

I'm sure a lot of people with OCLF will migrate to z4mod so a step by step guide for wannabe techies like me would be a great help.

Could anyone be willing to write additional update.zip packages that can convert /dbdata, /system, /cache, etc.? Many thanks!
[Galaxy S I9000 Themes and Apps] z4ziggy:
anyone can do this - just generate update.zip file and edit the updater-script.

also, shortly RyanZA will be adding "advanced" options to allow those conversions to the apk, also supporting other filesystem formats.

Great. I'll post mine up if I get around to it, otherwise I'll wait for RyanZA's next release. Thanks z4 for your z4mod and thanks RyanZA for bundling this!

Z4ziggy: i had to re flash the phone:-P

Nothing worked right. So i just tough it was something wierd on it.

I was right.;-)

So i did re flash my kernel and used Ryanza app to apply ext2.

It worked.

But the update.zip i did make from the git did not work.B-)

Now all seems to work good.

So you can add my custom kernel to the working list:-P

I will post a new kernel to ny post later.

[Galaxy S I9000 Themes and Apps] RyanZA:
Wrong thread for the update.zip method (although I guess feel free to post it here if you want) - this method is for testing the app version before it gets released to Market. It's likely that the app version may only ever convert /data, as /data is 95% of the issue, and reduces the chances of causing problems for users.

Advanced users can use update.zip or just manually copy init.d files, I think. But this may change.

/data having zero free space is unrelated to z4mod, as it doesn't change free space (or rely on free space?).

My bad, GT-I9000M added to the list, I forgot it.

I have no contact with Samsung or Canada so I can't answer your questions. The root removes all the files it installs when you unroot, but not anything changed by any root requiring apps you used while rooted. Your best bet would be to flash a stock firmware using Odin before taking it in.

As far as the purpose of this thread goes, still waiting on some reports! :D

So far we now know that it does not work well on a number of custom kernels (although it does work on the BLN kernel), and that it works on the I9000 2.2.
[Galaxy S I9000 Themes and Apps] RyanZA:
Looks fine, but obviously whether you want to test it or not is up to you. :D

I believe the i5800 has separate download mode from kernel as well though, in which cause it is 100% safe. Not sure how you would easily determine that for sure, though.

EDIT: First post updated with more info.
[Galaxy S I9000 Themes and Apps] FadeFx:
in german forum we had some cases where people did flash a new firmware with odin and after a failure could not get to downloadmode anymore... but i think this was possibly caused by an error during bootloader writing. however, i will go into myself and see if i will do it or not ;-) how can i check if the zimage fits into the partition on the nand?

[Galaxy S I9000 Themes and Apps] jamesyl:
Yea sorry I didn't realize your app integrated the update.zip process as well -- I was thinking the update.zip could be edited by hand prior to hitting that particular button.
[Galaxy S I9000 Themes and Apps] Prasad:
Is this similar to OCLF, in the sense that it'll reserve some amount of the 2GB ROM for apps and rest for lagfix ? As in, will my total app memory reduce like with OCLF ? In that case, I'd stick with Voodoo. Else, I'd like to give it a try :)
[Galaxy S I9000 Themes and Apps] FadeFx:
no it wont, it converts the whole partition to another filesystem. the difference to voodoo is that you can apply it to the kernel of your choice
[Galaxy S I9000 Themes and Apps] omaga:
Worked just fine in my galaxy with stock 2.2 great tools you made Ryan for us!
[Galaxy S I9000 Themes and Apps] RyanZA:
That kernel contains sztupy's lagfix. It would be a bit strange if it worked, to be honest.

Oh that's very good to know... Thanks! :-)
[Galaxy S I9000 Themes and Apps] Prasad:
I'm having an issue... The app get stuck on the "Downloading patched kernel from server..." stage... As in it won't proceed forward...
[Galaxy S I9000 Themes and Apps] rdy2go:
My fault, it's /system that has zero free space.

Steps:

FRESH FRESH FLASHED JPA/JPP ROM using KIES

1. Kernel downloaded and flashed successfully (patched JPA stock)

2. Attempting to change filesystem to ext2.

3. Everything works fine - /system is mounted rw/etc/etc

4. Reboot

5. No conversion

6. FS is still RFS not ext2, /system contains large /system/convertsplash file that makes /system "full"
[Galaxy S I9000 Themes and Apps] RyanZA:
How much free space do you have in /system after a clean flash? I have 12mb of free space, which is generally enough for most things. I'm guessing you are using a non-512 PIT which really can't be recommended. I'll try think of a way around this, perhaps with putting additional files in /sdcard.
[Galaxy S I9000 Themes and Apps] _JKay_:
You are right! My GPS is also not working!! And I cannot convert back to RFS!! Damn you!!!!! I guess I need to hit the big reset button and flash all new firmware!!
[Galaxy S I9000 Themes and Apps] mikextr23:
At first i thought my GPS was not working as well since i've waited for like 5mins to get a fix but wasn't able to get one. But the next day before opening NDrive, i enabled my GPS first and let it stand for like a minute then i run NDrive, immediately i got a fix. I don't know if it's just coincidence or what. I will try it again tonight and see if it still works.

By the way, my battery also tend to discharge faster after z4mod lagfix, and not to mention the default other mail app seriously lags big time on me. But generally speaking, the overall experience tends to get better over time with regards to day to day uses of the phone (again with the other email app exception).
[Galaxy S I9000 Themes and Apps] doc_2nas:
thank you for the quick reply Damian, but maybe it's only my feeling but I feel when I combine both lagfix my system is faster,compared to z4mod only, I've tried only for one day and still stable. I've read that oclf is also done optimization in SQLite database too, is that true? any comments? thank you so much guys
[Galaxy S I9000 Themes and Apps] DamianGto:
Hmm. I have never tried Oclf over ext2. But if it works then you got a loop back system.

It means if im not wrong that you got a ext2 partition on the ext2 filesystem instead of a ext2 partition on the rts filesystem.

Maby it will be faster sometimes but its not so safe.

Oclf do write to a cache if i remember right and that why you always get higher score on Oclf. But it do write it later. So its a false score.

[Galaxy S I9000 Themes and Apps] DamianGto:
One note.

Gps can take over 10 minutes to get a lock if your Gps is not up to date. Your phone must get new data. If you have Agps on it use to get faster.

If you move around before you get a lock it can take long time.

Just let it lock before you move.

And no this lagfix don't break the Gps. It should make it a little better for the system gets smother/faster.

And to use a custom firmware can also make the Gps better.

That is for timing in custom kernel is often tweaked and that make all program run better.

Both my kernel and speedmod kernel has been reported from users that Gps works better then stock kernel( speedmod had a bug with his i/o scheduler and he tweaked that so it works better and the Gps seems to work better again)

Just tested my GPS again awhile ago on my way to office. It worked but it took a very long time to connect. And the biggest thing i noticed is that it's displaying my location way off the road. It was not like that before i applied the z4mod. It was running perfect on my Ndrive and iGo it's just now. What GPS software are you guys using? Do you have the same experience as me? Google nav doesn't work from where i come from so i can't test.

Now if i want to revert to rfs. Do i just do that inside z4mod app and convert back? Or do i have to do something else first before doing that? Will i loose all my data after reverting back to rfs?

Thanks!

I'm too chicken to use kernel as i'm afraid that i might f#ck up my phone and i don't want to start from zero again as i have lots of data on several apps i'm using. I will try again later my GPS and see if it gets better.

In the meantime, would you know if it's just a matter of clicking the pull down menu in z4mod app and choose rfs if i want to return to my default system?

Thanks again!
[Galaxy S I9000 Themes and Apps] DamianGto:
Well you shall always have a backup.

I do one new every day.

If i do mess up the phone with to much test i can just reflash it an put the backup on.

Has saved allot of time for me.

If you choose rts and hit the button then ut shall convert back to rts filesystem. Make sure when you do that you have no other apps running.

Hi Ryan,

How do i know if i uninstalled z4mod already? I already changed back my system to RFS and restore the kernel. But when i open up z4mod app again after doing all those stuff, I still see below the app saying "Your kernel has been patched, and is now ready to be flashed to your device. Press the 'flash kernel' button to complete this operation and reboot your device". <<<< so does this mean, my kernel is still patched by z4mod and still not in the default/original kernel that came with froyo? If so, how do i completely get back to vanilla kernel withouth doing factory reset?

2. Run z4mod, one click to patch kernal, then reboot

3. Change rfs to ext2 by another click

4. Reboot and done!

Was waiting till version 1.0 would be realeased but since this thread has been quite quiet I decided to just install z4mod 0.9.3. Before I installed it i wanted to start fresh so I did a internal sd format and factory reset. Rooted with z4root (thanks ryanza) and then installed z4mod. Installation very simple and straightforward. Im a complete novice with roms and kernels so I was very happy it is as user friendly as OCLF. After installing there is an option to revert back to original rfs and probably back to original kernel (not sure).

Anyway performance wise there is a huge difference. Was using OCLF before and for now it seems z4mod is giving me much better performance. Thanks Ryanza and keep up the good work.

Hi guys,

It's my first time trying to root a phone, so I'm sorry if I sound like a noob.

I followed instructions from a page on dkszone (forum won't allow me to post the link).

However, after rebooting my phone (samsung galaxy i9000) after installing the program, when I tried to run the program it crashed some of my other programs and my phone started vibrating non stop. I then proceeded to reboot my phone but now its stuck on this flashing samsung load screen.

I tried doing a factory reset with home+power+up volume but nothing happens, I can however get into the download, do not turn off target screen with down volume+home+power.

Any ideas on how I should proceed next to fix my phone?

Also something that might have cause this might be because I just updated the firmware today on Samsung Kies? Or that I have AVG antivirus for mobile systems already installed on my phone? Would that have interfered with the program?

Thanks in advance
