Hello! After lurking for, well, forever I've decided to try one of these lagfix things. I've installed z4root then using z4mod patched the kernel and then converted to the filesystem to ext2 and it rebooted.

All looked good but once it rebooted and I went back into z4mod it said the current filesystem is still rfs.

Is there a step I'm missing or something I've done wrong? I have a Samsung Galaxy S, Froyo, GT-19000 JP5.

Try it again.

This time clear the memory before you do it.

[Galaxy S I9000 Themes and Apps] DorianGraph:
Okay, I'll do that.

Question, how do I do this 'clear memory' you speak of? (Yes, I am that new :S).
[Galaxy S I9000 Themes and Apps] RyanZA:
Any chance you could upload your extracted kernel here? What that error is saying is that your kernel did not upload to the server. Maybe some kind of proxy issue?

Probably because it's a custom kernel. Next version will include a full log detailing the error inside the app when the kernel fails to patch.

Could you post your /sdcard/z4mod.log file?
[Galaxy S I9000 Themes and Apps] ahhentz:
I have tried to use the online patcher again, this time from work, and got the same error. It actually takes a time to upload (there is even a progress being shown in the browser's status bar), and then the error occurs.

The extracted kernel image is attached.

Also, there was an error in the z4mod app, like this one:

Any idea why it happens?

[Galaxy S I9000 Themes and Apps] iqbalbaskara:
Hello Ryan,

If we patched with 0.9, have 0.9.2 installed, should we unpatch and repatch the kernel with this version? or should we just update the app and leave it be? Thanks!
[Galaxy S I9000 Themes and Apps] ramiawad99:
can it be completely uninstalled ? and can i revert to the stock kernel without falshing it again ? anyone tried to uninstall it and revert to stock kernel without flashing ?

Thanks.
[Galaxy S I9000 Themes and Apps] PandaKiller:
Only I know is that I install the official Android 2.2 from Kies using the registry hack and after this I install CF-Root v1.2 with odin to put back the recovery 2e.

I think that is the original 2.2 kernel.
[Galaxy S I9000 Themes and Apps] DamianGto:
Hold the home button pressed and you then choose taskmanager.

Go to ram and choose level 2.

Now it ends all program and you then you start the program.

If you did go back to rsf then you can flash original kernel.

If you put an original kernel on a system with ext2 then your data will be gone.

[Galaxy S I9000 Themes and Apps] RyanZA:
Yes. Very easily done!

First convert back to RFS with the convert button. After reboot, use the 'Restore kernel' button. You will be back to stock then.

Always use the latest app version when doing a conversion though, as there are bugs fixed.

You can just update the app. The only thing the app handles is the conversion, and the updates are just to improve the conversion and fix bugs in the conversion. :)

CFRoot is a custom kernel.

I'm still getting the same error with 0.9.3 :"zimage test failed". And still not connecting to internet when I press patch kernel
[Galaxy S I9000 Themes and Apps] iqbalbaskara:
Next question: should we convert back to rfs and then back to ext2 with this release then? Thanks in advance! :)
[Galaxy S I9000 Themes and Apps] RyanZA:
No need, it should be fine without doing that.

This is fixed up now. Was a 'max post size' limit in PHP on dreamhost, which I've found and raised.

Of course a kernel that big can't possibly be stock, so it's not like it's going to work anyway. :)
[Galaxy S I9000 Themes and Apps] brn85:
RyanZA,

I installed OCLF 2.0 and z4mod.

I still didn't run any of them.

Which of them should i run?

I'm on JPA from Kies.
[Galaxy S I9000 Themes and Apps] Spike_M:
good job ...
[Galaxy S I9000 Themes and Apps] ahhentz:
Well, now it uploads fine, but throws the following error

[E] Non-stock initramfs found (linked init)

That's weird, because I haven't changed my kernel yet :confused:. The only modification I did on the phone was rooting it. Please correct me if I'm wrong, but rooting doesn't touch the kernel image at all, right?

As I said before, my phone a brazilian variant (i9000B), which includes 1seg digital TV. Perhaps the kernel is bigger because of the drivers for the TV tuner? Now about the linked init thing, I have no idea. Could Samsung have used a different initrd filesystem layout for this version?

Thanks a lot! :)
[Galaxy S I9000 Themes and Apps] tmcatalin:
Hi. I have the same problem (still rfs after applying the convert and restart ) and memory clear didn't help.

In addition, I don't have the log scared/z4mod.log.

Thanks
[Galaxy S I9000 Themes and Apps] PandaKiller:
So, ken I install your Z4mod Kernel without any problem?
[Galaxy S I9000 Themes and Apps] DamianGto:
It should not be any problem.

Check that you have root with z4root after that.

Then you can use z4mod.

Kernel recovery lost at latest version

Hi, I really liked your Z4mod. It's really easy to use and works really well. However, I used the 2.0 version with all of that. Lately, I removed my 2.0 version (while already rooted and converted to ext2) to replace it with the latest one, but then the recovery button to the old kernel is gone. Is there a way I can go around this?

Thanks.
[Galaxy S I9000 Themes and Apps] DamianGto:
Most problem you have is just for you have upgraded to froyo.

You do have old settings left from 2.1

that's never good.

You need to do a factory reset. Wipe the catch and format the internal sdcard.

You will loose all data on the phone.

But you can make a backup on.the apps you have.

After this you can root and use z4mod to apply a lagfix.

[Galaxy S I9000 Themes and Apps] jerkysans:
Thanks, Damian.

Geez. I know I shouldn't trust Sammy on their updates. Lol. Anyways, do I need to un-root and revert my phone to its original kernel before I do a factory reset? I don't flash a stock ROM or anything, right?
[Galaxy S I9000 Themes and Apps] RyanZA:
Your filesystem is still RFS in that log, and you do not have a /etc/fstab. 99.9% chance that means you haven't done the convert. You need to convert your filesystem. :)

Ouch, okay. I only tested updating the app, not removing and reinstalling it, which appears to wipe out the backed up kernel. Next version will fix this. Sorry. :)

If you want to restore your kernel, you will need to flash it manually. Not too tricky.

Completely impossible. No stock kernel will ever interject a script before the Android init, which does mean that your kernel is non-stock. Maybe someone flashed one for you when you weren't looking. ;)

The next version of the app will detect this though, and give you a list of patchable kernels to use (advanced option only).
[Galaxy S I9000 Themes and Apps] jerkysans:
Oh. Thanks, Ryan. I thought z4mod will do that. So there's no need for me to do a factory reset of my phone like what Damian said? Also, can you point me to where I can find instructions to change my filesystem from RFS to EXT3? Would I just need to re-run z4mod to do this? Should I have done this initially before running z4mod? Is there an app that will do this conversion? Do I need to revert back to the old kernel before doing all these? Sorry so many noob questions going on right now. Thanks a lot!
[Galaxy S I9000 Themes and Apps] jerkysans:
@RyanZA, Found it and now converting my Filesystem to ext2. Got like 7GB of files to be converted. How embarrassing, though. Lol. But glad to be learning. Thanks, will see how it works now. :D
[Galaxy S I9000 Themes and Apps] humbak:
Successfully patched Jpjpa kernel with damiengto kernel 200 version, through odin. Later rooted wih z4root without any issues. Converted to ext 2 with Z4mod. No problems noted except couldn't replace framenet for battery mod with root explorer. Some space error proped up. Otherwise phone performed excellently. Repeated the whole exercise twice with identical results.

Then tested Jpjpg kernel, rooted with cfroot. Conversion with z4mod failed while patching. Reflashed damiengto kernal 200.

Applied cfroot and converted successfully to ext2 with z4mod.

This time no problem with the use of root explorer. Everything now working fine.
[Galaxy S I9000 Themes and Apps] rlorange:
Z4mod is not on the market. Might be a quirk from my phone only can anyone confirm?

Z4root is there tho a message from ryanza mentions google pulled it, pressure from samsung?
[Galaxy S I9000 Themes and Apps] ahhentz:
Holy crap, that's weird :P Well, the phone does have carrier customizations, maybe THEY did it. Bastards :P I'm sorry for the misunderstanding, but since I did not flash any kernels, I assumed it must be a stock one. I have not considered that my carrier could have a custom one. Well, does this mean no easy z4mod for me? :/

Anyway, thanks for your time. :)
[Galaxy S I9000 Themes and Apps] RyanZA:
It's not on the market yet, because it's not ready. It will be up on the market when it hits version 1.0.0, probably within a month. :)

What's not ready? Other partitions converted besides /data, kernel selection, advanced options such as tweaks, UI improvements.

I'll check out that kernel manually and try to work it out, but there is almost no chance that your carrier would do that!

Haha no prob, you're not the first to have this issue! The UI needs a bit more work still, which I'm busy on. :)

Guys, I have a Question... I have a GT-I9000 version but don't have the 3 buttons recovery mode... this is a must to root my phone?

can I brick the Phone if i try to root the phone without the recovery mode activated??

thx in advance

Regards from Chile
[Galaxy S I9000 Themes and Apps] RyanZA:
It's possible to brick your phone if you don't have recovery mode. Any reason you don't want to fix that first?

But anyway.. you don't need recovery mode to root your phone or anything like that.
[Galaxy S I9000 Themes and Apps] ahhentz:
Well, then someone must have done it while I wasn't looking :D

Ryan you're amazing!! I use I9000dxjpa stock, and it works flawlessly, I love your OCLF as well, and in the beginning of using them, I	found OCLF is faster than z4mod (not based on quadrant but in daily use). Can we still use the minfree and scheduler tweaks for froyo, or they're only for eclair? thank you so much. Keep on the good work

Hi Guys, I've used Z4mod version 0.9.3 and now my phone is running so fast.

Doing some testing i have formated the internal SD and now when I run the z4mod i miss the [Restore Kernel] option. I've tried reinstall the application but is still missing.

right now only appear the [Convert file system] option, so i can restore de RFS file system if i need, but i'm not sure if could be a problem miss the option [Restore Kernel] for future phone updates, using kies.

There is a way to get back the option [Restore Kernel] ?

I've done something stupid and seriously messed up the phone. I have updated to Froyo (ZSJPE), applied z4root and then z4mod. I successfully switched to EXT2 but I accidentally converted it back to RFS. After that, I've tried to convert back to EXT2 and it seems like the process has partially wiped certain data on the phone as if I have done a factory reset. Almost all of the apps I've installed are gone (including z4root and z4 mod), my Google account was gone and so are all the contacts and calendar entries. However, certain things like the phone log and some settings such as the number of home screens are kept.

Is there anything I can do to save the phone?
[Galaxy S I9000 Themes and Apps] DamianGto:
No.

It seems to have wiped your user data. That's why you always shall do a backup before messing with the phone.

The best you can do now is start from the beginning.

[Galaxy S I9000 Themes and Apps] junglist1996:
Yeah, I was lazy and didn't do a backup and now I need to pay the price...

Can you please elaborate on what do you mean by "start from the beginning"? Would a factory reset do it? Or should I flash the firmware with Odin? Thanks.
[Galaxy S I9000 Themes and Apps] DamianGto:
Well that's how we all learn:-P

I would do a factory reset. Wipe the catch and format the internal sdcard.

Then i would check the phone that it worked like it should.

If not i would flash a new firmware.

If all is okay i would flash a kernel. Root and convert to ext2.

Then i would install all apps i wanted.

Also do all settings i want.

Then i would make a backup.

But that's me:-P

Ryan, is it possible that you could add 2e recovery into this app or in z4root, as this will make it a lot safer?
[Galaxy S I9000 Themes and Apps] SexyIceCream:
just installed z4mod today and its working awesome! even the net(using the stock browser) seems to load faster lol. and i know it wasn't related but i was still hoping for the video/audio sync to improve...haha! thanks ryan!
[Galaxy S I9000 Themes and Apps] RyanZA:
Well.. you can just copy it manually to /system like normal if your phone is rooted. z4mod does have an option to include CWM recovery into the actual kernel, but it's a little flakey. It'll be an option in the advanced bit of the app when I get that all done.

Not sure what you mean by video/audio sync? I've never had any issues with that, even on 720p high bitrate with sub titles.

It can take a long long time if you have enough files. Leave it for 30 mins or so before pulling the battery, at least.

I need to add some type of spinning image to that conversion page to show it's still doing something... Just need to work out how. Separate process perhaps...
[Galaxy S I9000 Themes and Apps] SexyIceCream:
@ryan darn, really? cause on my stock froyo sgs i noticed a slight (around 0.5sec) out of sync between audio and video! posted my observations and apparently i'm not the only one( hate it when the lips don't match the sound __|__) ...i was hoping it's due to system lag, but the lag is gone and the problem persists >_< ah well completely unrelated...thanks for your response!

Did the factory reset, wipe cache & format internal SD. The phone seemed to be working normally but I've flashed the phone again just to be safe. Spent a couple of hours last night to set up the phone including z4root & z4mod. I must say I'm really happy with the performance now. Everything (except Quadrant) seems to be much faster with almost none of the lag I had with 2.1 & lagfix.

issue

hello guys, I'm a real noob when it comes to the android system so please excuse any nonsense that I might write below...

I have a galaxy S and I had froyo on it with z4root and z4mod (ext2). due to some issues with some apps I had to factory reset it and used titanium back-up to restore all my apps including z4mod (which I think was a mistake).

1st question - should I have converted to rfs before factory reseting?

Now after this factory reset Z4mod look strange: it sais that my current filesysem is rfs, in the dropdown box I get only ext2 (if I remember correctly, when I installed it first time there were more options), the text below starts with " now that your kernel has been patched..." (but I didn't patch it after factory reset) and if I click on "convert filesystem" it sais that it does it, it reboots that phone but nothing happens :| i still have rfs, after reboot

2nd question - what have I don wrong, and most important, how can I fix it... it seems that I have to come back to the stock kernel, but how... can you please help me?:( (keep in mind the noob thing)

thank you!
[Galaxy S I9000 Themes and Apps] yuriac:
There is a way to undo this Lagfix without loose data or something?

Because i did the lagfix and all worked smoothly! But i wanted back to normal, to install the new version (1.3) and i did the "Restore yout Kernel".

After this i loose everything hehe. I know that was my fault, but would somehow to back this lagfix?
[Galaxy S I9000 Themes and Apps] DamianGto:
Try to run the z4mod again.

Do check you still have root.

If it don't work do a factory reset again, wipe the catch and format the internal sdcard.

Make sure first you have the backup on a safe place.

Then root the phone.

Use z4mod to change to ext2.

Then check the phone so all thing work.

Then put you apps back. Don't put any system data back.

Hey RyanZa,

First, I really want to say thank you for your work.

I wasn't that impressed when my Galaxy S switched from Eclair to Froyo, but as I used the Z4root then the Z4mod applications, I discoverded a new phone !

Quick, smooth, impressive.

I've just noticed one thing. Froyo has drasticaly boosted the battery autonomy, but since I use the lagfix, the battery turned back to a mediocre autonomy. Is there a link or is it just a feeling ?

My phone is a Galaxy S from Bouygues Telecom (france) Froyo 2.2

No flashed kernel, and the only upgrade is the Z4mod.

Anyway, keep up the good work !

Thanks for the reply. So does it mean you also get the same lag as i do? Coz from what i remember when i used oclf when i was at 2.1 my phone was blazing fast! And reading the first post of Ryanz here, i was under the impression that this is "better" so i assumed this lagfix is faster.

By the way, don't get me wrong my gmail app becomes faster after this fix, its just the other mail app that is really really lagging especially when i'm opening it. Just want to know that it's not just me. Rest i can live with but since i always use the mail app, it tends to bother me knowing that i applied lagfix already and still getting the same lag. Maybe its Samsung's fault again!

NOTE: I have 4 email accounts configured on the other mail app. (yahoo, rocketmail and two hotmails) opening them one by one is like 5-7secs lag and then another 7-10secs lag just opening each new email on each account.

Hi every one,

i would like to try z4mod on a galaxy tab, but another user reports a problem with the generated /etc/fstab (i guess).

http://xdaforums.com/showthread.php?t=842119

If i get it right, z4mod patch kernel to add ext2 support, then patch to make it use of /etc/fstab file to mount file system. (what does the original kernel use to mount fs when not patched?)

How /etc/fstab could be different after using z4mod ? I guess z4mod scripts list mount point before and after conversion. I've searched what i could on the forum, does someone know where i should continue reading ?

Thanks a lot !
