EXT4 on stock ROMs

Hi guys, n00b question here.
Is it possible to convert the filesystem on a stock flash to ext4? E.G: Flashing a stock ROM, then flashing the OverCome kernel. Will that work?

Yes - only flash a zimage that supports ext4 ex. overcome_kernel with odin or heimdall.
Make sure ure a GSM or CDMA user so that u flash a correct kernel for ure phone.

Thanks very much : ) Tried it and it worked perfectly.

That doesn't answer his freaking question. I have a p1000 also which I bought already rooted and I have no idea what it is on. Knowing how to determine what you are on would be very helpful. You see every ROM thread talk about both but you never see anything on how to figure out which one you are on.

type 'mount' in terminal emulator
if you have MTD, your /system is mounted from /dev/block/mtdblockX
'cat /proc/mtd' give you details for the mounts.

Are you serious? He said he was on overcome and asking does he have mtd or not.
My answer clearly indicate that since he wasn't on cm9 , he has no mtd.
Of course by now there is aokp mtd too.
But still, no overcome with mtd.
If you have question, just post a new thread, no need to bash me for something I answered in good faith LAST MONTH.

Calm mate hehehe, but i think overcome 4.1.0 already come with mtd correct me if i'm wrong..
Like another post has been said, For OP if you dont mind try type mount in your terminal or you can look into /proc directory, have mtd file or not?

No. Overcome never has mtd.
Only bml but uses ext4 fs.
Need to say this so no newbies confused.
If you are on overcome, you are on bml.

Ah i see, because i follow stimpz0r guide for flashing aokp rom and he say to flashing with overcome first if you come from non mtd so i think overcome using mtd and after that we can flash aokp rom based on mtd....

It is clear that overcome is bml not mtd, and at least you need overcome kernel to have updated CWM recovery for conversion to mtd

So if I am not on ICS roms, that would mean I have a non-mtd. But what are the non-mtd's that I may have on my ROM? if I am on a 2.3.6 based ROM.. what do I have?
is MTD a file system like window's fat32 and NTFS, or is it something else?

1) No. MTD is not a file system. it is a partition scheme.
Just like MBR for most windows system and old linuxes and the new GUID partition table in OS X and newer linuxes.
The MBR is the one that let you have up to 4 primary partitions (due to a 2-bit room for definition, I think) and the rest have to be in extended/logical partition.
So, BML is proprietary Samsung, and MTD is open source one.
Filesystems is fat, fat32, ntfs, ext2, ext3, ext4, yaffs2, HPFS, you get the idea.
2) yes, before ICS I doubt there is a custom rom for gtab that has MTD. So Gingerbread is 99.9% likely non MTD.
Tricky to find what ROM you have. Even the one that has touchwiz, could be stock, overcome, acudroid.
Non touchwiz one could be CM7, BOCA, hyperdroid, etc..
I don't know how to fingerprint them, but the Setting | About may tell a lot.
See which kernel is that listed there and all other version strings there and google them, you may find a match.

Priyana, thanks for the detail yet simple explanation regarding types of extn. Now I know what extn I got on my phone Lately I have been thinking of flashing ICS rom (Im on overcome 4.1 rightnow) but since I am not sure whether all the apps and games on my phone will work on ICS. Through some light on this. I will be using titanium bakup. Thanks in advance.

How to install aokp build#36 and cm9 ICS 4.0.4

Pls teach me to install ics easy to follow...tnx
Sent from my GT-P1000 using xda premium

Are you familiar with flashing with Odin? Or specifically restocking using overcome method?
Basically
1) go to overcome site and download the gb stock safe and overcome kernel. And also download ics stuff aokp or cm9 and gapps.
2) flash the stock from
3) flash overcome kernel.
You can check my post here for more details of the 3 steps
http://forum.xda-developers.com/showthread.php?t=1626825
Or if you are on gb based rom, you can just start directly with step 3)
4) boot to the new cwm recovery that overcome kernel comes with and flash ics (may need to do twice) and then gapps.

Downgrade to GB

Hello, I've looked around to find this answer but couldn't find an exact match. I want to downgrade from rocketrom ics to stock GB 2.3.6 using odin, my current. Kernel is franco. My device is checked and known to have dangerous eMMC bug. Is it completely safe to flash stock gb from rocketrom?

Hi guys,
Im on Stock ICS XXLQ2 can i flash stock GB XXLC1 using Odin PC after that i can do Full Wipe/Factory reset etc..
Thanks

I got the idea i need to flash the Open europe version of stock GB via odin. But the one I found is Wipe version, will this trigger the eMMC bug? (my device is affected)

Afaik the full wipe part will be performed under the gb kernel as that is flashed before the from, so you'll be fine.

Sorry but i need to clarify this
So, is it ok to flash any rom with safe kernel? For instance CM9 RC1? I'm on official ics 4.0.3 from samsung, and like most of the note users i have the f*ing bug

Cm kernels will not work with tw based roms, only with aokp/aosp, and vice versa. You'll have to read up on the kernel pages themselves on which rom types they support.
So flash to gb first, perform full wipe, root and install cwm, then you can install custom kernels and roms from there. Never install from ics kernel, only downgrade to gb to be safe.

Downgrading to gb means; directly flashing a gb rom right? Yes, i'm new to all this.

hi everybody
i am sorry for bothering you i just want to ask when using pc odin to downgrade from ics to gb stock rom is enough one pda file or i had to use the other phone and csc file with pit file and repartition, that is my first question.
the second one after flashing the stock gb can stay on stock kernel or it is unsafe.
thank you in advance

Most of the rom files split down into three files but If you place the original tar file into pda, odin sorts out the partitions correctly for you.
All stock gb kernels are safe from emmc superbrick bug, safe to perform wipes.

help downgrading from AOKP mtd

guys i need help, are there any risks downgrading from ics to gb? i could use odin anytime but as i am new to p1000 i need more information risk free before i proceed . ive heard this tab is prone to hard brick when downgrading.

Not true.
I did it a few dozen times.
If P1000, safest is to use overcome method.
Follow my signature, download gb-stock-safe-v5 and PDF guide, and overcome kernel.
Turn to page 7 and follow that to restock to GB first.
Then follow the guide to flash overcome kernel to get CWM.
then use cwm to flash ICS or restore old nandroid backup.
