Okay. Then its just because the bug in the latest z4build then.

That's why it tried to apply the change.

Z4ziggy is working on that problem:-P

Hope he will solve that soon. Right know Im on stock filsystem with my new kernel. Lol.

[Galaxy S I9000 Themes and Apps] RyanZA:
Hah... Okay that's pretty strange. What method did you use to root btw? Perhaps it's a busybox conflict of some type.
[Galaxy S I9000 Themes and Apps] Whitehawkx:
Hmmm the rom/kernel I flashed came pre-rooted. Now that I think about it, I was using the stock JK2 kernel but it has a custom init script to allow the use custom boot animations. Could this be effecting the conversion process by chance? Anytime I manually root though I use OCLF from the market.

Hey RyanZA,

I see that there is a list of devices in the first post but I dont see a listing for the GT-i9000M specifically. I see the i9000, i9000B and i9000T but no "M". Is there a reason for this? Is the i9000M considered in the generic i9000 family? Also...

A bit off topic here but I am curious to know if I root using z4root and need to unroot for warranty purposes, will it remove ALL traces that it had been rooted including Busybox and Superuser app?

I know that Samsung has issued a memo stating that if a phone shows up rooted to a service center that the warranty will be voided and Id really like to try this rooting method.

Also, as you are probably aware, the i9000M here in Canada has issues with internal sd card failures and I am curious to know if just rooting with z4root will possibly kill my internal sd?

Thanks...

The problem is with CWM recovery - it's busybox-tar is not working properly.

Hi, I converted to ext2 with z4mod but my phone got slower than ever, even moving between screens is jumpy. Also I got a problem with my wifi not connecting anymore. Also the conversion wiped my data, logs, settings and some apps.

I would like to restore RFS to try to recover my latest backup from CWM but when I go into z4mod app again and select to convert to rfs I get the following error message:

Error: /data/data/com.z4mod/files/z4mod (permission denied)

Very good, tested yesterday: ext2 seems stable, fast, battery efficient...

But without cwm/recovery/backup nor RFS back, it's hard to often change kernel for testing the others: I need (I think I'm not alone in this case) a stable, fast ... kernel for working but from time to time, for testing other kernels, I need a fast way to come back with this one or another...

I'm not so fond of this version...

I used one of DamianGTO's Kernels and then applied the conversion with z4mod tool. Sadly this somehow corupted parts of my data and left me with a half-working phone. Facotry reset in Clockwork also did not work and I could not restore to rfs. I was coming from Speedmod Kernel and never had problems like this there.

I had undone all lagfixes from Speedmod, so this should not have been a problem.

Now I reflashed the Speedmod K9 kernel without restoring rfs and it actually works. I did a factory reset in Clockwork, restored my apps with Titanium (this did not work while using z4mod) and now everything is working fine. I would love to know what filesystem I'm on at the moment...maybe I should find some shell app and look up the commands...

UPDATE: I just checked and mount gives me data as being on ext4 for some reason. This makes no sense because I used z4mod to convert to ext2 and when I put speedmod back on I did not select any lagfix...weird that...something must have gone wrong.

[Galaxy S I9000 Themes and Apps] DamianGto:
Well its clear that you had your system in ext4 with speedmod kernel.

That's Why my kernel did not work.

If you read the first post in my tread i do write you shall flash a stock kernel first to make sure all things work before you flash my or other Z4mod kernel.

The thing is many do have problem to go to other kernels after speedmod kernel.

My kernel don't support ext4 so its no way you can change to that with Z4mod.

We do compile the kernels and that's very different from patching it.

Is this faster than the ULF-based kernel lagfixes?
[Galaxy S I9000 Themes and Apps] DamianGto:
Wrong.

If the kernel you use support ext4 you can change to that.

There is alot if talk about ext2 vs ext4. Ext2 keep getting blame for data lost and corrupted data.

Well nothing is true and its a bad myth. People just don't understand this is not spinning disc and you don't need journal that most people think they need.

And many people start now to remove journal and stuff from ext4 to be more like ext2.

The true is that ext2 is the best filesystem for sgs (data).

And the most kernel use the same lagfix base and ext2 is not supported in them.

That's why i did my kernel in the first place.

What about writing an own benchmark app? Just startet a thread about this in the app section. I agree quadrant gives you just a number, but with a refined benchmark (testing different read-write situations on different partitions) one maybe see clearer differences between the different lagfixes...

Yes we need a benchmarks program that's made for sgs.

That would show more true numbers.

Hello all,

This is my first post here so take it easy on me. Thank you RyanZa for the work you have put into these apps and others who have contributed as well. I was running the JPA official FroYo build and I ran Z4Root + Z4Mod to convert to EXT2 file system. I will test out how it goes. My question is:

1) to revert to stock, I see a restore kernel option in Z4Mod. Do I just hit that and I will get back to completely stock?
[Galaxy S I9000 Themes and Apps] lenrek:
You have the same problem as me. I fix the problem by manually download the original kernel and restore it using Odin. After that, I rerun z4mod until it works.

[Galaxy S I9000 Themes and Apps] jacklmx:
Phone got wiped..or i believe so.

My galaxy S I9000 got wiped i think, after i convert ext2 file system to RFS, then restored my previous kernel, all done through z4mod. after the reboot all my apps including android market are gone. all the customization i did eg. theme, wallpaper, settings are gone too, everything returned to what a phone would be like freshly out of the factory. Hope anyone can help me as i am really new to all the modding flashing etc. I followed all the steps mentioned by Ryan and in z4mod, didn't do anything else.
[Galaxy S I9000 Themes and Apps] RyanZA:
The problem here is that the conversion script is picking up your /data partition as already being EXT2! Confusing, since you say it isn't.

I think I understand the problem though - your /etc/fstab file must still show /data as being ext2, even though it isn't.

Correct way to fix this is to actually check that the filesystem really is ext2, and not rely on /etc/fstab. Or, (better actually!) the app should check out the /etc/fstab and make sure it's all in order first. Thanks for the bug report!! :)

The CWM recovery in the z4mod git has a few issues still (well they might be sorted now actually). At any rate, that option will be included in the next version, or the version after that if the CWM in git still isn't working 100%.

No! Make 100% sure you are back on RFS before using the restore kernel option, or your data will be lost. It won't actually cause any problems if you want to do a reset though. Next version of the app will check to make sure you are on RFS before flashing back.

Sounds like the ext2->rfs conversion before your reflash did not work, or alternatively you changed back with /data being on ext2. Post logs if possible. :)

[Galaxy S I9000 Themes and Apps] ahhentz:
Hi there. I'm new to this Android modding stuff, and so I would like some clarifications before I try using one of these lagfixes so I don't do anything stupid :-P

I understand that z4mod uses native ext2 instead of loopback mounting. So this means that the app backs up the partition's contents, formats it and then reverts the backup, right? Also, if I understand correctly, the kernel must be patched before the actual lagfix process is done. Why does it need to be done? Is it because stock kernels don't have built in ext2 support?

In a related note: how easy/safe it is to revert the lagfixing process? My question is because of warranty. My handset is relatively new, and if I ever need to use my warranty, it would be better if I have it as close as possible to a factory configuration.

Now on an unrelated (possibly a little off-topic) question: is there a good resource for technical explanations about the update.zip file? Under the hood stuff. I searched the forums and found nothing.

Thanks in advance.

Is it possible to add a (customizable?) initscript via z4mod? In order to add kernel tweak options such as ones found in the SpeedMod kernel, possibly?

Same here, once on JPA and now on JP7 (stock both fw).

After trying z4mod - patching > EXT2 > RFS > restore kernel, my phone got wiped only after restoring kernel. It was ok after the RFS conversion.

So this hapened twice for me and for other people/phones.

V0.9.2 is up in the first post. I swapped the 'Custom kernels' back to 0.9.3, and brought the conversion screen text up to V0.9.2.

Also fixes a very important bug - the EXT2->RFS conversion did not work correctly in 0.9.0, so you MUST install 0.9.2 app before using the EXT2->RFS conversion. :)

Custom kernels are still slated for V0.9.3, and additional partitions for V0.9.5, but this may be reversed too, since custom kernels are obviously very tricky.
[Galaxy S I9000 Themes and Apps] iqbalbaskara:
so for us 0.9.0 is the filesystem conversion mandatory? or should we just install the apk and leave it be until the moment we need to revert back to RFS?
[Galaxy S I9000 Themes and Apps] RyanZA:
Correct - You only need it when you are going to convert.

Do not use the old version anymore.

But if you are already converted, then there is no need to download or use this until you want to convert again. :)
[Galaxy S I9000 Themes and Apps] fredphoesh:
very poor performance - voodoo far better.

Hello Ryan and all

I came from a clean install of v8 Doc's rom, (no other lagfixes chosen) and installed your app, patched the kernel, rebooted, and found the phone intolerably slow. I did it all again because I could not believe it, and again, extremely slow.

I then did not wipe anything, but booted to recover and applied voodoo and found my phone zipping along really well... so I dont know why that is, but in my repeated experience, this lagfix was really laggy, worse than no lagfix!
