Sorry guys, I thought I could handle this, but I just tried to update to Hakuro's new rom, but I think my problem is something else. Let me explain.
I used to have H's Cupcake build and I just wiped, installed the radio, installed the SPL and installed the new firmware. I used a Linux machine for format my 4gb memory card with 3gb fat and 1gb ext2 and I extracted the zip file into its own folder.
I have tried doing an "adb shell ls /system" and it shows there are no files there. Have I lost root access? Is that what would make that folder vanish for me?
if you're booted into recovery, /system isn't mounted.
is that the case?
Ah, yes. I guess I was getting a little over worried about nothing. So at least I don't have to worry about 'that' being the problem of why my phone keeps rebooting.
I can wait until the main thread gets unlocked... Unless anyone wants to share some ideas?

if you didn't wipe, i'd def try that
I did. I expect that doing "adb shell ls /sdcard" should work in recovery, correct?

/sdcard isn't mounted in recovery, either.
if you do:
adb shell
...then...
mount /sdcard
you can read / write to the card just fine
Ahh, I thought a messed up the Apps-SD step. I'm getting a message saying:
"mounting /dev/block/mmcblk0p1 on /sdcard failed: Invalid argument"
Hmm, my Linux machine sees the partitions just fine.
/dev/sdb2 fat32 2.74GiB
/dev/sdb1 ext2 1.00GiB
Both appear to be primary partitions.
I tried doing a "busybox df -h" in ADB and it didn't list my SD card.
When i try to push or pull anything it says, e/ddms the file cannot be pushed because its a read-only file system. Any help?

You have to remount the FS in read/write mode.
With adb it's 'adb remount'.

Happens to everyone at times. Don't sweat it
So what do you do, if you run adb remount
and it still say's read-only system when trying to push?
been dealing with it for a few days, looked all around the forums and didn't find anything that helped :-/

Good question. Unfortunately I have no idea. Never seen it fail. theoretically there's a command line you can run in adb shell to mount the FS read/write, but I can't remember it off the top of my head.
Something like mount -o rw /dev/m3blk (as I said I can't remember the exact filesystem name). I'd do a search for 'mount -o' on the forums. It's been posted more than once and I'm too lazy to find it for you
I believe you're refering to
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
if so, tried that too :-/ still nothing
i read someone had reformatted their card on xp vs 7, so tried that to and still nothing haha
i give up
thanks btw
Yeah, I'm having the same problem as you sometimes. Other times it works. It's very strange! It annoys me. Anyone have any idea on a fix?

Have you tried that from recovery? Are you using a2sd and if so, what ext?
Are you able to mount the card as a disk drive? Are you sure the SD card isn't going bad on you?
Sounds like you've checked anything else I would have thought of...wish I could help.

Well i'm actually trying to flash a new recovery (all in the pursuit of installing flipz new fresh rom with ext4 haha), so was doing it from the computer
I tried using a2sd but i'm pretty sure it didn't work, because i went to ext4 and to my knowledge fresh 2.0d can't use ext4, so yea, i fail
i am able to mount the card as a disk drive and can move things back and fourth via explorer, play music, everything except this seems to be fine, it's only a few weeks old, so i really hope it's not dying

That could be it. ext4 doesn't play nicely with ext3 based stuff. It's 'semi' backward compatible (meaning you can mount ext4 as ext3) but it seems to have some serious inconsistencies that way. I'd recommend a re-partition and then upgrade ext3->ext4 AFTER you install the new ROM.
Heh. I had all KINDS of problems restoring an ext3 based nandroid after upgrading to ext4. Had to repartition and then restore the nandroid to get it to work.
well, loaded recovery, re-partitioned my sdcard, upgraded to ext3 and left it there, still nothing
the sd card wouldnt have any bearing on the ability to adb remount.
the /system partition is stored on the phone itself, so the mount -o ..yadda yadda
remounts the /system partition in this case /dev/block/mtdblock3.
the only reason a sd card would come to play is if youre runnign a2sd, in which case it makes symlinks (shortcuts) to the sdcard, if the sdcard is formatted improperly then a2sd will either cause a bootloop, or crash and then youre phone should boot normally but you wont have access to your ext4 partition (the partition with your apps).
im not sure how to fix a problem with adb remount, perhaps try a new version of the SDK or just a clean one.
good luck
I'm wondering if there is something wrong with my mounting
When i'm in the shell
if i cd /sdcard
then do a ls
nothing is returned
I've also directly copied the recovery image from my computer to the sdcard, and attempted to run the flash_image command and it says no such file or directory
I do have usb debugging enabled and am selected to mount the sdcard, is there some other step or something i'm missing?
nenn, i had actually just a little bit ago downloaded the latest sdk on a completely different machine and still same results
Alrite, so I was able to copy the image recovery from
explorer and flash from.terminal on my phone
Although I'd prefer to work from the pc, anyone have any other possible ideas?! I'm at a loss

Is it possible to mount the sdcard in /sdcard and the internal memory to a different location?
Android does not appear to work with /etc/fstab. There is /system/etc/vold.fstab but his does not appear to be working in the same way /etc/fstab in Linux.
Anyone has this working?

Not sure if changing the mounts is a good idea. CWM for the iconia seems to look at the external_sd so it might break that.
Hello guys.
I was looking for a similar guide to link to my friend but didn't find anything, so I decided to write my own.
Personally I didn't find any good guide regarding partitioning from android itself, so I think it's also more unique guide because you can easily make your own partition layout without using PC at all.
Why I should use EXT4 instead of FAT/exFAT?
1. We're running Android, Android is based on Linux. EXT4 is native linux-proposed filesystem, while FAT/exFAT is not.
2. All our internal partitions (/efs /data /system /cache /preload) use ext4, natively.
3. CM has poor exfat support, while fat32 is not recommended for big file systems (over 2 GB) because it doesn't work well with them, thus microsoft implemented exfat.
4. EXT4 has better stability and performance, especially on Android devices, compared to exfat and fat.
When you should not use ext4 over fat/exfat?
- When you for whatever reason use your external sd card in windows environment physically. Android works in MTP mode, you'll use your ext4 external sd card the same way as you use internal one under windows. But if you for whatever reason puts your external sd card f.e. in usb adapter connected with windows then it won't work. So yeah, if you keep your external sd card in your phone then you're fine.
Expert Way (Requires fdisk/mke2fs utilities (busybox), works always):
1. Launch any terminal from Android environment (f.e. Android Terminal Emulator or adb shell through PC)
2. Make sure you have root (su command)
3. Make sure you have all required utilities. Type fdisk --help and mke2fs --help, both commands should print usage. If you get "command not found" then you don't have required utilities. Either install Busybox or CM-Based ROM with native busybox support (tested on ArchiDroid 2.X)
4. Unmount your external sd card (umount /storage/sdcard1)
5. Launch fdisk partitioning program on your external sd card (fdisk /dev/block/mmcblk1)
6. Destroy partition table (o), create new partition , make sure it's primary (p) and first one (1).
7. You can check if you're satisfied with your partition layout (p). When you're done exit and save changes (w)
8. Create ext4 filesystem on your partition (mke2fs -t ext4 /dev/block/mmcblk1p1)
9. Reboot
Android should automatically detect and mount external sd card in ext4 after reboot.
Here you can find a short movie which shows going through expert way recorded by me
Intermediate Way (Requires USB Adapter and some patience, should work like a charm):
1. You'd need USB Adapter or any device which can read micro sd cards on PC
2. Open any linux-supported partitioning program (f.e. partition magic, gparted, parted), it needs to support ext4.
3. Delete all partitions from your external SD Card (typically, one fat/exfat) and create one ext4 partition.
4. In case you'd also want hardswap create 2 partitions, one primary ext4 one and second primary swap one.
Newbie Way (Requires PhilZ Touch Recovery, may not work):
1. Launch PhilZ Touch Recovery
2. Select "Mounts & Storage" => "format /external_sd"
3. Select "ext4" as a filesystem
4. Please note that it can take some time. This way you should get running ext4 filesystem, but personally I didn't test this method, as I prefer more advanced ones .
This guide is more or less universal but I'm using sgs3 external sd card paths so I want to make sure nobody bricks other phones . Personally I suggest using expert way, as it's probably the easiest one.
Hit thanks if it helped, I hope it did .
@JustArchi thanks for the tutorial. Now for the sake of sdcard wearing. I would like to disable Journaling. How do you do that?
EDIT: also i noticed after formatting the externalsd card there is 3 GB occupied by nothing (?) This is normal?

tune2fs -O ^has_journal /dev/block/mmcblk1p1 should do the trick. You can put it in init.d if needed.
Also no, you should get full size of your sdcard. Are you sure that you've firstly destroyed partition table (o) and then created new full-size partition , as showed in the video?
You can use fdisk also to get information about your external sd card and find why is it smaller than it should be.
HI, My 64gb is two partitioned one hardswap and other primary.
Will I lose data on both partitions if I delete partition and format to EXT4?

You will lose data contained in the partition you are formatting. If you leave the other partitions untouched, you won't lose their data.

Just don't use (o), as it will destroy everything. Use an option to delete selected partitions (d, if I remember correctly) and create them through n.
System Data
Hi, thanks for te help, but now a have a 1 gb lost by system data or 0.8gb if i disable the journaling, that is right??? Thanks

It depends on your rom and also if you created ext4 properly. I've formatted my 2 GB SD Card to EXT4 and I got 1,80 GB free (yes with journaling). This is because 5%-10% is reserved for "super blocks". Read more -> http://en.wikipedia.org/wiki/Ext4

Hi Guys,
I am new fairly new to rooting and using terminal emulators.
I have a rooted samsung galaxy note 2 with superSU, busybox and shell terminal emulator. I verified fdisk and mke2fs
(fdisk --help and mke2fs --help) but then when I tried the command
"umount /storage/extSdCard"
I get the error message "Operation not permitted"
Can anyone tell me why this might be?
Thanks
/storage/extSdCard is the path to the external sdcard on my device.

I did not.
However, I did try again and got the sane result. I used these commands in shell terminal emulator:
su -
mount
umount /storage/extSdCard
result: "Failed: Operation not permitted"
I have verified root with root checker...and after typing the command "su -" I was prompted by supersu to "allow"
I believe this issue will likely be something simple that I am not aware of.
I have tried this on my galaxy note 2 and my tab3 8.0 with the same results.
I really appreciate any help offered.

Thanks Archi. I was wandering around looking for a solution to the problem with my sd(I'm nooo0b if it goes about Linux/Android ).

Okay, you're user, not root. This is a weird android shell, that's why.
Try to use "su -i" to get root shell, then use fdisk (without su).

Try android terminal emulator, you must gain root shell. Typically "su" command does that, "su -l" should as well.

Hello Archi and thanx for the tutorial
I followed all the steps, done it to the end, but after reboot I couldn't make any folder on SD card.
Card is recognized, formated as EXT4, but for some reason there is no way to put anything to it
Tried again with gparted, ended with same result.
Tried to change ownership, but that also didn't work out...
Now i reverted card to fat32...
Any idea what could be wrong?
btw, using NeatROM 4.4.2 with boeffla kernel and Philz 6.00.8
thanx in advance

Your rom doesn't support mke2fs properly.
I've given up on reformatting the internal memory as EXT4 (my last post). However now, I want to mount an external SD card that is EXT4 (or any file format that has UNIX permissions). I can't get my device to mount the card, it says the filesystem is unsupported. Now, that's bull**** since Android has built in support for EXT. After searching threads here on XDA and Google, and even purchasing EzyMount as recommended, I can't get it to mount. I've tried BusyBox and mount commands (as root), with various errors such as "mount operation not supported on transport endpoint". I'm at my wit's end by now, trying to get some filesystem which has support for symlinks and UNIX permissions... any ideas?

you fully rooted with custom kernel or only with rdlv etc?
First you gotta figure out how to mount this damn thing, gotta be possible.
Then you need to get this done on bootup, either in init.rc or init.d or smth.
You probably just use wrong commands? But I could be wrong, didnt try that yet but would also be interested. Having the file permissions also on SD would be nice, but it could cause trouble with mtp maybe?

I am rooted, but stock ROM and kernel. MTP is for connecting to a computer? If it is, I don't need that. I have tried
mount -rw -t ext4 /dev/block/mmcblk1p1 /storage/extStorageCard
and variants switching the flags and options.
Interesting... I just typed that command in to make sure I didn't make any typos.... and my phone crashed and rebooted. I typed it again to see if it would cause another crash and it appears to have mounted the card! Whwn I type "df" at the prompt it now shows a 28.6 GB filesystem at that location, which has to be my sd card.
Why, how, I don't know. It works, it's all I can say.
