To clarify, CF-ROOT is thus far GB (and at that KPE, KPH and JP5 releases) only.

This ext4-format.zip file however, is a script file which can be used in any Skin1980's CWM (incl. CF-ROOT), regardless of Android version.

To reiterate, this is just a script which will convert most of your system's mount points to ext4 from the Samsung stock rfs format.

This script must be installed from within CWM RECOVERY, after taking a NANDROID BACKUP. Immediately (i.e NO REBOOTING) after the script it's done, RESTORE the previously mentioned nandroid backup. Now proceed to reboot.

Clarify before embarking on such procedures, and make sure you read, and understand, the steps and the risk/reward fully.
[Samsung Galaxy SL i9003] adaba:
I installed using the flash update option putting the ext4 zip file into my sd card, hopefully I didn't get any problem right now, i'm going to try it in cwm recovery mode right now, another question that I forgot if I asked or not, what is zip-align?

Thanks for your help
[Samsung Galaxy SL i9003] adaba:
Hi again, I had some problems and was getting samsung logo loop, flashed back the XXKPH PDA with odin but it didn't fix it so I flashed to XXKPE then XXKPH and now the CF ROOT custom kernel, just did a backup with cwm, in recovery mode I chose "install zip from sdcard" and chose the ext4 script, then I had to restore it as you said but it's written "MD5 mismatch" ?

Thanks for help
[Samsung Galaxy SL i9003] Baladya:
1-Do we need to rename to update.zip?

2- Where do we place it in the external sd (anywhere?)

Thanks all
[Samsung Galaxy SL i9003] Erahgon:
No need to rename it. Just place it anywhere in your external SD card.

You need to choose "install zip from SD" in the CWM menu and navigate to the file.

Follow the instructions to the letter!

[Samsung Galaxy SL i9003] ravindrank:
I have done fr 2 phones on kph and works fine.. Steps:

1. Goto cwm

Boot loop?

Guys I've been stuck at the Samsung Galaxy Super Clear LCD screen for more than 10 min now 0.o

These are the steps I followed:

- download the ext4 script and put to ur external sd card

- enter recovery do a full backup with nandroid;

- then select flash zip (DO NOT REBOOT AFTER THIS STEP);

- hit back button n restore backup.

- reboot

I did this exactly :S What should I do now :/?
[Samsung Galaxy SL i9003] Erahgon:
Try flashing again and restoring your backup (no ext4 conversion, just stock with recovery). Tell us what happens.
[Samsung Galaxy SL i9003] Baladya:
Flashing what?
[Samsung Galaxy SL i9003] AmirolAhmad:
@baladya

what firmware u r using? Gingerbread or froyo??

u must know this thread is only for FROYO! (read first page)

CF-root by skin1980 has built in EXT4 as i know. check ur system by entering "mount" on adb shell or any console program like terminal emulator to know ur file format.

if u r already using gingerbread than u flash this update u must has a problem..

correct me if i am wrong :)
[Samsung Galaxy SL i9003] Baladya:
Yes i am on Gingerbread, and I read that it was made for Froyo, BUT...

And Skin said this:

http://xdaforums.com/showpost.php?p=17553780&postcount=901
[Samsung Galaxy SL i9003] AmirolAhmad:
hav u check ur system? whether in EXT4 or RFS using adb shell or terminal emulator?

one more thing, if quadrant score higher than 1900, so ur system already in EXT4 format..

correct me if im wrong :)
[Samsung Galaxy SL i9003] Baladya:
Dude the thing is, my phone is not starting at all. I restarted and pulled battery and still stuck at logo, so i can't view quadrant.

btw if i install adb will it detect and work with the phone since the phone doesn't boot?
[Samsung Galaxy SL i9003] AmirolAhmad:
try dalvik cache clean, factory reset/data..

if not, try flashing back cf-root by skin1980 the latest one, 05sept..if the probs still happen, there is no other way except flash XXKPE then XXKPH then flash cf-root..then do dalvik cache clean
[Samsung Galaxy SL i9003] Baladya:
Cleared dalvik cache and factory reset, still same.

Are you sure its safe flashing CF-Root at this point?
[Samsung Galaxy SL i9003] AmirolAhmad:
Everybody here need to take the risk..we learn from the risk.. I've been flash my phone about 10-20 times..I changes cfroot between amit bagaria n skin.. I got no probs..but for u I'm not very sure how u'll done it..

If u r not very sure, ask person who r expert in this thing like skin n other dev..they will help u..I'm just give my opinion what I've done before to my phone :)
[Samsung Galaxy SL i9003] Baladya:
hehe you're right :P So should i just go into download mode and flash CF-Root like I did last time ?
[Samsung Galaxy SL i9003] AmirolAhmad:
I think, yes :)

If it doesn't wotk, u need flash xxkpe n xxkph back
[Samsung Galaxy SL i9003] Baladya:
Aright CF-Root didn't work so i flashed firmware back (btw I use JPKP5 so no need for XXPKE)...

Hey AmirolAhmad have u converted to ext4 while you are on gingerbread? If so, u used the script on this thread?

Thanks a lot man
[Samsung Galaxy SL i9003] usmankh10:
before applying cf root or any rom which supports ext 4

do we need apply file available in this thread???

or simply apply cf root or any rom???

although my device is rooted plus deodexed running xxkph
[Samsung Galaxy SL i9003] Baladya:
I don't know if you can apply it without CF-Root but what i am sure of is that you can flash CF-Root before converting to ext4( i.e you don't need to apply it to be able to flash CF-Root
[Samsung Galaxy SL i9003] AmirolAhmad:
Before i apply this zip, I checked my system and its already ext4 then I try to apply this zip and its converted my system format to rfs. I dont know y..

After that, I change it back to ext4 with flash it back to xxkph..

So now ur probs solve? If yes try check ur system format in terminal emulator after applying cfroot
[Samsung Galaxy SL i9003] Baladya:
Woah that's weird xD So I should download Android Terminal Emulator and type "mount"? Then what should I check for?
[Samsung Galaxy SL i9003] Erahgon:
@Baladya: If you're using JPKP5, check if you are using CF-ROOT for JPKP5.

Also, if it doesn't work, just use XXKPH. It's stable enough.
[Samsung Galaxy SL i9003] Baladya:
Ya i am definitely using the right CF-Root man :P

Cmoon nooo I want JPKP5 xD I need the arabic support :P I'll try contacting Skin and see if he knows something :)

btw when i type "mount" in Android Terminal Emulator I get lots of directories and stuff, what should I look for to know if the system is ext4 or not?
[Samsung Galaxy SL i9003] AmirolAhmad:
U should found word ext4 in there..if not u'll will find word rfs..just search in there
[Samsung Galaxy SL i9003] Baladya:
Yup, 'rfs' is there. Any advice what should I do now :|?
[Samsung Galaxy SL i9003] AmirolAhmad:
that's mean u r still rfs file format, not ext4.. try applying the script .zip found in this thread..carefull :)

btw, what cf-root u r using??
[Samsung Galaxy SL i9003] Baladya:
Tried again and works this time :D

Btw plz edit the OP and remove the "Only for Froyo" cuz it creates confusion ;)
[Samsung Galaxy SL i9003] AmirolAhmad:
Congrats :)
[Samsung Galaxy SL i9003] jarego:
i have a question. do you really have to flash it to stock FW in order to get ext4?

and after i get ext4 after flashing it to stock, can i reflash it to any other FW and still have ext4?

THANKS...
[Samsung Galaxy SL i9003] Skin1980:
You can get ext4 with any rom you want... just follow the guide.

You can flash all FW you want but you will lost ext4... just redo the steps
[Samsung Galaxy SL i9003] AmirolAhmad:
skin,

just this EXT4 conversion working for XXKPM??

[Samsung Galaxy SL i9003] AmirolAhmad:
no dude..its work fine..u must be doing something wrong.. my first try attempt was failed..but my second attempt, woowww its work on XXKPM :)

guys, im jsut curious..why if still has RFS at the certain part.. does it mean Im not convert at all or what ?

here u r:
[Samsung Galaxy SL i9003] mitoVonDido:
successfully converted to ext4 using OP steps.

BUT after that need to factory reset coz all apps are greyed..

since i backed up with TB first that should be no problems :)

so it works for XXKPM
[Samsung Galaxy SL i9003] Skin1980:
Not all partitions will be converted but only the needed.... no improvement on converting all
[Samsung Galaxy SL i9003] Skin1980:
There's a problem with ext4 conversion....i'm working on it.
[Samsung Galaxy SL i9003] calvinljh:

I have question about the ext4, knowing it have better performance.:eek:

Do i feel different? I change my external memory as internal memory instead :confused:
[Samsung Galaxy SL i9003] AmirolAhmad:
Noted! Thanks for de advice.. waiting ur new ext4 conversion
[Samsung Galaxy SL i9003] Skin1980:
The problem is not in the conversion but in the reboot... i became made under froyo to understand why i cannot convert to ext4... but i will explain better on CF-ROOT thread
[Samsung Galaxy SL i9003] usmankh10:
any update reagarding new version of ext 4

i knw u have bought sgsII :(
[Samsung Galaxy SL i9003] Erahgon:
Why? What else would there be to update in a formatting script that's already doing it's job?

Maybe when they finally make an ext5 or zfs or something...
[Samsung Galaxy SL i9003] fliph:
i'm using kpm with latest cf-root

just like to verify the step by step to convert to ext4

1. make a backup

2. install .tar file via odin, phone automatically reboots to cwm recovery

3. install .zip file via cwm recovery

4. restore backup via cwm recovery

also after converting to ext4, what would happen if i flash kpm again? do i loose the ext4?

thanks!
[Samsung Galaxy SL i9003] pabreu:
interesting question..

if i'm not wrong then u wont lose ext4 unless u select in re-partition in odin.

so if u only flash a pda file in odin, then u wont lose ext4.

WARNING: but if u do so, it will cause a bootloopcause stock kpm doesnt support ext4.

you will flash cf-root for kpm again and after booting your system should be already ext4.
[Samsung Galaxy SL i9003] fliph:
is this ok?

1. make a backup

2. install .tar file via odin, phone automatically reboots to cwm recovery

3. install .zip file via cwm recovery

4. restore backup via cwm recovery
[Samsung Galaxy SL i9003] Erahgon:
Nah not really...

1. Install CF-ROOT.

2. Make a Nandroid backup (i.e. in CWM recovery).

3. Install the ext4-format.zip which is in the OP (which you should have moved to your external sd-card upon download).

4. Restore the Nandroid backup.

5. Restart the phone.

DO NOT RESTART THE PHONE UNTIL YOU HAVE COMPLETED STEP 5, DOING SO WILL CAUSE A BOOTLOOP AND YOU WILL HAVE TO DO A FRESH INSTALL OF THE FIRMWARE!!!
[Samsung Galaxy SL i9003] fliph:
i got 2226 on quadrant after i converted to ext4!

thanks Erahgon and skin!
[Samsung Galaxy SL i9003] fliph:
I am now on xxkpm ext4. Do I need to do anything if I want to flash to a different fw? I am thinking of going back to kf1. Kpm is so laggy
[Samsung Galaxy SL i9003] Erahgon:
Since the stock kernels don't have ext4 support, it's recommended you start from the beginning again. I.e. Flash the firmware and once again follow the steps outlined above.

You're welcome! :)
[Samsung Galaxy SL i9003] fliph:
so just flash straight to kf1 and i won't have any problems? thanks!
[Samsung Galaxy SL i9003] Erahgon:
Nah, I recommend you start from the top (the .pit file and all).

Although you could experiment around, but I can't guarantee the results!

Its okay to bump old threads if you have a similar problem or you solved an unsolved problem. Bumping old threads is annoying when its just saying that "it works great" and stuff like that. To learn new things you don't post these things right? Instead head to the great FAQ falex has compiled in the general section and read it ;)

[Samsung Galaxy SL i9003] falex007:
I have the problem with your mod :( I have boot looping.

I did the following operations:

1. removed files

2. made backup

3. flashed PDA (after reboot it stays on Samsung LCD logo)

4. removed battery and enter to the recovery menu, but after selecting install from zip it was frozen

5. reflash PDA again (again the phone is frozen). But recovery works well.

6. applied ext4-format.zip

7. Restore system from backup

8. After rebooting I got boot loop

to restore I had to flash back XXKB3, then I flashed CWM, then I formated /cache, /system, /data and /datadata. And then I restored date from my backup

[Samsung Galaxy SL i9003] ephraim:
how many minutes does it take to boot buddy?

edit: do i need to wait for it to boot after flashing then go to cwm to install the zip file or can i just remove the battery to go to cwm?

Ohhh.... sorry falex, I misinterpreted, thought you got stuckt restoring backup. But I dint face bootloop, after all those steps. May be you should try again.

Can't we restore to original state by flashing previous CWM and and those three deleted files? We will also need ext4 to rfs script.

May be skin can help us in this regard.
[Samsung Galaxy SL i9003] donytsang:
Thanks Skin for your great work on our device.

I would like to ask:

In step 2 we make a nandroid backup with CWM, after flashing the PDA, installing the zip file from CWM, do you mean I have to perform a restore action by using CWM?

Can't wait to try your great work, howcome I am still in the office.

Thank you. :D
[Samsung Galaxy SL i9003] falex007:
NP. No, I already restored nandroid backups without problems (BTW I like that it restores all applications even when I make repartitioning! ) OK, may be this is my luck :) I'll try again and again while I don't get success :)

No, we can't restore: CWM can't flash partitions it can't mount (I don't know why) I tried. That's why I had to reflash full firmware.
