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)

What can I do? I can't use CWM because it can't mount the sdcard. So I can't use the z4mod app and I can't use the update zip to restore to RFS.

How can I restore RFS so I can at least try to restore my backup? Will flashing with Odin restore RFS or will I just brick it?
[Galaxy S I9000 Android Development] AlexandreT:
I uninstalled Z4mod and reinstalled it (about 3 FCs in that process). Its now converting again. I hope in the end I'll have RFS back.

What could have gone so wrong? It was a fresh flash, your latest kernel (everything was fine up to that point) and then when I used Z4MOD app everything got so bad. I am a bit lost as to what happened...

Let's see if I can restore my phone to working condition anytime soon.

Thanks anyway.
[Galaxy S I9000 Android Development] DamianGto:
Strange it should not happen.

I have tried this method about 10 before i posted it.

If all was successfull it should not be slow.

I will look into it.

Maby its the Z4mod app i got that's not right. Don't know if ryanza has a newer one.

That is exactly what happened to me.. I had to reflash to a stock eclair rom and re-pit to fix it.. Hope it's easier for you. :-)
[Galaxy S I9000 Android Development] betoNL:
Trying it right now....342 MB Ram.....cool:cool:

But what is the z4mod.rfs.update.zip for

??

The Z4mod apk is doing all the (re)conversion and (un)patching in a much neater way?

I flashed the z4mod_12_1_v1_300hz

What are the differences between this and hardcore's K9 300hz ?

Responsiveness looks alike..... K9 have more tweaks? 1 MB Ram less?

I dont use lagfixes, didnt convert file system

[Galaxy S I9000 Android Development] DamianGto:
That file is only for old kernels that need to converting back. Should not be used with the new ones.

Z4mod app is easy and it looking good.:-P

Hardcores kernel is much more tweaks and he has alot more support for different things. He also use the initramfs from sztupy.

So that kernel is far away from stock kernel. Mine is very close to stock.

Its more for people that want more then stock, but not so much custom kernel like hardcores.

If you converting to ext2 you get more speed.:-P

So I think you should edit the third post. The instructions are a bit unclear:

You should add for instance, in which case the update file should be used.....be carefull with instructions...

Not really, at least not for me..

Since I was on Eclair, I always dedicated time to RAM Maintenance, never experienced lag , but tested some lag-fixes anyway:

Those lag-fixes improved those overrated quadrant benchmarks, but didn.t improve nothing on the user-experience level at least in my case.

They did add sooner or later instability and problems, newbie/user-related or not.

My motto is: don't mess with something that you don't fully understand and/or really don't need....(unless you are rich, with lots of spare time and tweaking is your game;))

[Galaxy S I9000 Android Development] DamianGto:
Well people should always read the first post. That post is always updated. That's how it works here on this forum.

Ext2 do speed up things, but this kernel is for froyo.

I've tested alot of things and ext2 filesystem is the best way to speed up things.

Quadrant score is only to make sure the fix is working. Else its useless.

But hey, this is your thread, if you dont want to edit that 3rd post, that's you call.

Sorry for trying to help

That's what I said about quadrant benchmarks. I Don't care about it,it's overrated as I said. I am just looking for the user-experience improvement.

And I tested lag-fixes on JPM ,JPH and JPA dutch, as well....

Don't need lag-fix and dont need the eventual hussle (when things do go wrong), my sgs is fast enough.

I can change it but its old and people do understand that old message is not always right.

It make note sense to change old post all the time for things change all the time.

First post is always right, then you should read the whole tread. Then you should know what's right or wrong.

Many do read the first post then jump to the end. They know its fresh information there, but if the tread is small its better to read the whole tread and understand all of the topic.

Im glad for your efforts to help, but this time you are wrong.

Also this tread is about to speed things up with the kernel and apply ext2 to the filesystem. If you think you don't need it i don't see the point to use it either.

But thanks for your thoughts.:-)

I read an earlier post from someone getting problems after flashing youre kernel over cf-root kernel. Didnt really get what was causing his problems.

I have cf-root but would really like to try out youre kernel. Is it possible to flash youre kernel over cf-root, root with z4root and then use the app with lagfix without problems?
[Galaxy S I9000 Android Development] radeon_x:
Guys - I applied this kernel, and I applied the z4mod ext2 conversion (to JK3). Everything went fine.

I rebooted my phone, and now I'm getting the dreaded:

E:Cant mount /dev/block/mmcblk0p1

(IO Error)

e:copy_dbdata_media:Cant mount SDCARD:

Looks like my phone is dead. Unless there is some way to recover from this I haven't heard of.

Anyway, I don't know if this kernel or z4mod is to blame - but it does seems like suspicious timing. Flasher beware!
[Galaxy S I9000 Android Development] DamianGto:
Most problem people get is when they come from other custom kernel.

They way to flash other kernel is to undo everything the kernel you are on.

Then flash a original kernel

If all is good on original kernel then this kernel will work. Just flash it.

I was using the BacklightNotification kernel before, that was it.

I have an I9000M and an using the I9000UGJK3 2.2 firmware.

I am in Clockwork recovery, and I can still get to upload mode - but when I try to mount /data I get "Can't mount /dev/block/mmvblk0p2 (No such file or directory)"

Any ideas would be most appreciated!
[Galaxy S I9000 Android Development] DamianGto:
Never tried it on that device or with that firmware.

Clockwork don't work 100% and it can be difficult to mount a ext2 filesystem.

If you did have a backup it is easy to flash back original kernel and go into recovery and wipe the cache and do a factory reset. That would get the phone working again.

[Galaxy S I9000 Android Development] DamianGto:
A quick fix for the problem with clockwork recovery to mount sdcard.

Use it on your own risk. make sure you do have a backup ;-)

Unpack the file and put it in system/etc/init.d

restart the phone and go into recovery and now mount sdcard shall work.

Hi DamienGto,

I wanted to try the new version again since you provided a quickfix for CWM but I can't revert my /data back to rfs.

When I ran the zip file on CWM, it completes the update process but after rebooting the phone I noticed that it's still ext2..

Okay.

Go to the Z4mod website and download an update script from there and try that.

Hi Sir,

I am a beginner when it comes to linux or android for that matter. However I love flashing in different kernels/setups to my devices. (started from my Dell x51v).

In this case, will it be all right to flash your kernels on top of one another? I am currently on 200Hz and ext 2 (z4mod) and a stock DXJPA ROM.

Thanks in advance for your attention!

I read about corrupted kernel, I have k9a speedmod and it is safe.

for example I download from samfirmware JP7 firmware, and contains 3files(code, modem, csc) all file .tar.md5

I will rename in .tar (code file), than extract (contains: dbdata.rfs, factoryfs.rfs, param.lsf and zimage).

Than I keep only zimage and create .tar

It's right the procedure??

At the end I must rename .tar in .tar.md5 ?
[Galaxy S I9000 Android Development] DamianGto:
Yes it shall be zimage only in the tar file. If you have linux you can easy make a tar file. In windows its hard to get them working.

It worked without any hassle :) when i switched from cf-root directly to zImage_z4mod_12_01_v1_300hz kernel. I was a bit worried after have read in z4mod forum about people installing z4mod directly on cf-root kernels and getting problems with there phones.

Root (from cf-root kernel) was still present after the flash and i could successfully install z4mod. The phone feels really fast!

Thanks for youre great work with the kernel DamianGto

[Galaxy S I9000 Android Development] DamianGto:
The kernel and the converting to ext2 seems to work.

The phone can be hot when charging. That's normal if you use it in the same time.

The vibrating is often for some program is not right and they crash.

This has nothing to do with the kernel.

Did you had any other custom kernel or lagfix before on the phone?

If you did flash jpm and did factory reset and wipe catch, the lagfix is gone. But you should also format the internal card.

I have the very new India Froyo update..

Phone - I9000DDJP2

PDA - I9000DDJP6

CSC - I9000ODDJP5

So if i want the 300hz Kernel,, i just flash it over the current firmware using Odin without Repartition or anything else checked and then apply Z4root and Z4mod and convert to ext2??

Now,, i already have rooted using Z4root and converted the stock kernel using Z4mod to ext2 and the phone is running pretty smooth. Will i need to re-root and re-convert after i flash this???

Thanks in advance:)

thanks for your great work, i'm on zImage_z4mod_12_1_v2_300hz now. its still running really smooth, and i also notice that display on battery status is never more 80%, and its been 15 hours up without charging, that is the first time since i got this phone. :D

Hi Damian,

I already have hardcore's SpeedMod K9A installed, I wanted it mainly for the sharpness/color improvements and the BLN. I am quite happy, and I have converted the /data to ext4 once (by mistake) and the phone was very snappy, but the battery drain was huge, so I went back to no lagfix.

Now I am very interested in this thread and the z4mod thread (read as much as I can), it seems that converting to ext2 will not really affect the battery life (correct?), so I would really like to try it.

Now comes the question, I don't want to lose the sharpness/color fixes and the BLN, and I want to use the ext2 lagfix, how do I make that happen?

Is it possible to use the ULF built-in in the speedmod kernel and get the same fix?

ohh, ok.. when most people say they have root they mean they have root permissions, it comes from Linux and root having full permission to do basically whatever it wants. The levels just sound kind of silly tbh. :)

To be rooted you'll need the superuser.apk installed in system/app and su installed in system/bin. You'll also need a modified boot partition.
