[KERNEL] Gingerbread with EXT4 support and FS converter

As many people where demanding a Ext4 Kernel I created one and added a Filesystem conversion script.
This does only work on Gingerbread ROMs cause the bootloader is different!
On Froyo it will cause the device not to boot into the normal android system. Don't flash it if you are not on a Gingerbread ROM.
I have tested it with KPH but it should work on all Gingbread ROMs that have a updated bootloader.
FS converter? WTF???
This converts (formats) all your internal partitions (system, data, cache) with Ext4.
This way you don't have to use RFS which performance is pretty poor.
How to install?
Install CWM (there some threads here how to do this)
Make a Nandroid backup of your system (this is essential otherwise all your data will be lost!!!)
Install the ext4-update.zip (this will format your partition into EXT4 and flash a new Kernel)
Go into "mounts and storage" -> unmount cache (if it is mounted)
Go to "backup and restore" -> "advanced restore"
Choose the backup you made before -> Restore System & Data (cache is not needed it is rebuild on the next reboot)
Reboot
Don't panic (it will take some time to rebuild the dalvik cache,
just like the first boot after you flashed a new rom with ODIN)
Follow those instructions otherwise all your data will be lost and i make fun of you!
This will install a Kernel that has EXT4 support and a modified init.rc to mount both ext4 and rfs partitions.
Ok enough talked, where can I get this ****? Here MD5: 369808990ff8d45065f0cdd8fbb3f8b8
WTH you bricked my Phone
This is impossible. Except your CWM is buggy. You phone doesn't boot up, you are stucked at the samsung logo?
Ok then we need some information from you. Did you hear the start-up sound the the samsung logo player?
How long did you wait?
Try to adb to the phone and give me the output from "mount" and "logcat" on pastebin.com pls.
Please tell us witch rom you were running. I am not sure if this will work with any custom rom cause i only tested stock
You can fully revert by flashing a Full ROM with ODIN. Then install cwm and restore the backup you created before.
How did you create this?
I simply build the kernel source added Ext4 support. Kernel source is on github
Then I created a new initramfs by dumping the stock one doing the modifications and repacking it. The Initramfs is also on github. This should help anyone of you trying to the some on your custom kernel.

Cool dude ....
Is this a OC kernel ?>???
Nice work dude for this 1 ....
Appreciate ur work

Great work...
Getting ext4 support means it will format the sd card fully or just creates a partition with the free memory left in the sd card?

nope nothing touched except FS support. I think i won't add anything like that cause it want to save my time to work on CyanogenMod. But everyone feel free to modify the source and do it

it does not touch your sd card. it simply formats the internal partitions to ext4.

and what is FS converter????sry for noob question..

Are you working on CM for ACE? Thx for kernel, nice work. )

There is no RFS filesystem's source in your source, how do you compile a kernel supporting RFS?

samsung just give we modules for rfs support.

Its a journaled file system, meaning it keeps track of all changes made to the file system in a journal making it much faster than samsung's rfs file system.
@coolya
Thanks for this!
Does this Kernel only support SD card EXT4 partitions or does it convert the phone memory to EXT4 as well(thats what i understand by the FS coverter script).

it converts all internal partitions into Ext4, /system, /data and /cache

But how to use them? I want to build a Froyo kernel supporting ext4 and RFS.

that means it will also support SD card EXT4 APPS2SD partitions right??

the kernel is Ext4 enabled you can use where ever you want, you just have to mount the partition right.

is there any way to revert changes made? just in case we may want to claim warranty..
thank you for this awesome work!

[Q] Lots of errors

So hey all,
Recently my Galaxy just stopped working. At home I tried to install new firmware. Then I got a lot of errors.
This is what I get when I go in my Recovery Mode:
-- Copying media files
E:failed to mount /sdcard (File Exists)
E:copy_dbdata_media:Can't mount /sdcard

When I install new firmware I get errors the same like this.
Now I have tried to install all firmwares (from 2.2.1 to 2.3.6) and nothing works.
I had my Galaxy running on a costum ROM (I don't remember the name, it was something with Ario).
What to do? I'm quite lost..

Check My Android Solutions as to what may work for you

I had the same problem. My internal memory card was broken. I have received my repaired phone from Samsung service centre 2 days ago.

solutions for /dev/block/mmcblk0p2 or /mmcblk0p1 or /mmcblk0p0 are all never the same, it all depends on as to what caused the format failure .
You can try flashing the same ROM twice or more with different PIT ( i9000 has 3 PIT files)
But if the problem was caused by Lagfix, which you had failed to undo before a factory reset or upgrade...than your Internal SD card needs to be reformatted back to rfs.(vfat) ..which is why the stock ROM fails to solve the problem as your current format is in ext 4.
So nothing will work, IF your internal SD card had been converted to Ext 4 format, until you find a way to format it back to vfat.
For Korean version of Galaxy S , flashing an Eclair will solve all problems except this lagfix problem. So you can try the Eclair for i9000 at My Android Collections
Suggest you try to format your Internal SD card ( remove ext SD card and Sim Card) , before trying any ROMS

Well, how am I supposed to do that? My PC doesn't recognize my phone because it wont start. Therefore I can't format my internal SD.
How to do this?

[Q] Bricked/bootloop/no -recovery/ odin cant read file error, HELP?

Hi,
Ive been trying to get this phone working for about 2 days straight now. Tried all kinds of flash methods and so on.
But as of now, im officially stuck, and i dont know what to do.
I have this SGS i9000 with almost certain a broken internal SD (not sure, this is what i have tried to fix by flashing different roms/bootloaders/pit files,U name it)
I'm now at a point that only download mode is available and when trying to acces any recovery (original or CWM) i get the nice brick screen(phone --- ! ---- pc picuture)
Any Help would be apreciated.
Sorry for my bad english, im from Holland.
I don't know the original firmware or anything, i got this phone with bootloop error from a friend.
Thank you for all your help...
[EDIT1]
I am able to enter the Original recovery now, but a lot of errors are on the screen:
Do note that, there is NO simcard and NO External SD-Card in the phone present!
The errors in normal recovery are:
- e:failed to mount /data (file exists)
- e:delete_data_files: cant mount /data your storage not prepared yet, please use UI menu for format and reboot actions

when you get this (phone --- ! ---- pc picuture), you need to re-flash the correct kernel or correct ROM as its stuck in incomplete flashing.
when you get this cant mount /data your storage not prepared yet you may have mp3/junk file stuck in data and causing the issue, so remove Ext SD card, remove sim card before flashing dbdata.rfs file from here
IF that did not resolve it , flash a rescue kit from above link used for unbricking. i9000
Important
make sure your unit is i9000 and not a variant of i9000
charge your phone fully before flashing

Thank you for your reply,
I checked via Imei number what type of i9000 it is and its a i9000.
The phone is without a sim and external sd card.
As of this point a flashed other stuff and i now get failed to mount sdcard (file exists)
copy dbdata media: cant mount sdcard
please use ui.. bla bla...
media files copy failed.
Apllying Multi CSC
Cant acces system csc/kor/system.
Succesfully applied multi csc.
Is there a way to figure out what the correct rom should be? or is there like any 'universal' rom that would work on all i9000 phones?
I read your rescue page, and tried the one click jar file inside your resque kit and also via Odin but still i keep getting errors.
The original problem (when i first got the phone) is a couple of bootloops and eventually it would boot into android.
Whipe of data and cache would solve the problem but it got worse and eventually it resulted into a bootloop from which he booted into android after about an hour or so...
I though i had the right kernel/rom.. and so on...
I did flash a speedymod kernel which booted right into android and with sdcard function.
But it would give errors and bootloop and crash diverse apps (system apps)
I have rooted diverse types of phones before so i am not a complete noob in this area...
Any help on how to continue?
Thnx
[EDIT1]
After flashing dbdata i still keep the same error.
The rescue kit from ebase the download link of the pdf isn''t working.
Any help on that?
I will try all rescue kits available...
and let u know what it does(little hope but)
[EDIT2]
EZBase rescue kit gave me the following errors:
failed to mount sdcard (file exists)
copy dbdatamedia cant mount sdcard
please us ui bla bla bla
format volume rfs format failed on dev block mmcblk0p2
data whipe failed
Multi CSC
Cant acces /system csc kor system
Trying the other EZBASE reqovery now (CF-root and Semphore)
[EDIT3]
Same as in edit 2
[EDIT4]
Gbflashkit gives the following result,
media files copy failed (unable to read above that because normal recovery menu is displayed on top of it)
failed to mount data (file exists)
delete data files cant mount data
please use UI bla bla bla
Updating file system goes correct
wiping cache
formatting cache
cache wipe failed
applying multi csc goes correct!
I already tried de SGS resque kit but it also failed...
Any help ?
[EDIT5]
Did a whipe cache partiton and data/fact reset...
Now when booting into normal rescue i get this:
Copy media files
failed to mount /sdcard (file existst)
copy dbdata media cant mount sdcard
please use UI bla bla

After flasing dbdata again the error stays the same

this would be the clue as to one of the problem you may be having, basically at some point the phone must have been formatted to ext 4, as such samsung Stock rom will not be able to use it .
The solution here would be to flash a speedmod kernel for 19000 ( look in My Android collections ( link below) under kernels and flash that to get CWM, untick Auto reboot in Odin before flashing after that get into CWM recovery and format system & Data or everything back to RFS using CWM universal lag fix menu.
you can also look at My android solutions (link below) for solving mmcblk0p2 problems

In win7 in the disk module i can see a e and g drive but it says no media .. so im unable to do anything about it.

Basically this means your Internal SD card is corrupt , you can try ADB whilst in Recovery to see if you can pull anything from your internal SD card. Look in MY Directory (link Below) about ADB, if you are not familiar about ADB
or you can push a custom ROM into it to flash with CWM
The other option to get phone booting would be to use a two primary partitioned External SD card to act as the Internal SD card.

I don't get an android device listed in my hardware devices list... only under usb devices it will say a composite usb device...
Even tried a other pc (which is fresh) but no luck either.. when i put my own phone on the same usb cable it recongises it straight away.
So no probs with usb cable/pc.
Any help? external SD-card option, not an option in this case...
Any other thoughts?

[Q] I9000B OS doesn't load/ "Failed to mount /data" / Almost bricked

I got a long story here. First i got this Galaxy S TV (GT-I9000B) from a friend who broke it's Android and I thought i could fix it. I could restore from a brick status to a clockwork mod which failed because that CWM was made for I9000 and not mine which is I9000B. Then, I went to sammobile, downloaded everything to factory reset this phone using Odin. It worked, but when i tried to boot, this thing appears:

And beside this, the boot is stucked. It can't load anything. I tried using Heimdall to fix but some error (ERROR: Failed to access device. libusb error: -12) shows up, ADB can't access the phone. I also tried learn how to format the internal SD, go through every single error and fix each one but i got lost again and now i don't know what can i do.

Lenovo K3 Note k50-t5 internal storage mount issue with 0mb internal storage

Hey Guys I need some help ...!
Recently, found some issue on my Lenovo K3 note k50-t5 with custom blend rom marshmallow version stuck on lenovo logo so i tried to format everything with twrp (DenisePDA 3.0.2-6v4) version on my phone but unfortunately I am facing more issue afterwards as I've got No OS Installed/No Internal storage/No SD card it was showing everything empty the only thing I can access on my phone now that is to reboot on twrp with 0mb internal storage. I can't mount Internal Storage nor SD card but I tried to flash another version of twrp through OTG but no success. I also tried to change the file system from ext2 to ext4 but it failed. I tried everything like SP Flash tool to get back on Stock Rom but No success as it was showing BROM Error (4008). I also Tried to Re flash twrp with Fastboot method but all my attempt was failed. I hope if someone help me out how to fix an unable to mount storage issue on my TWRP atleast I might able to Flash rom again. Please Help...! If Anybody know how to fix or overcome this issue.
