Hmmm, thats weird. I couldnt mount it, asks me if I'm root or not :/
tried it with opensh, gives an error aswell:
How to check i now; Create another directory where you can do the mount, or if for example your /mnt/ is unmounted, do:
Code:
mount -t ext4 /dev/mmcblk0p3 /mnt/
When you can check that you actually HAVE the stuff that's supposed to be there, you can boot your device in maintanance mode, copy the recent stuff that you have in your rootFS /home/ to mmcblk0p3, delete all stuff under your rootFS /home/ to save rootfs space, and finally correct the thing why it does not mount it in boot phase.
I suspect you have played with your /sbin/preinit and changed the mount order...

I can't even mount it anywhere else either... Yes, not even on /mnt
It gives the same error as before:
/ # mount -t ext4 /dev/mmcblk0p3 /mnt
mount: mounting /dev/mmcblk0p3 on /mnt failed: Invalid argument

Is it possible that you need to try mounting under opensh (or adrianesh, or whatever it's called...?)
Also it's possible that your partition table is corrupted or your mmcblk0p3 is shomehow corrupted as being unmountable.
What does it say when you use fdisk to look at the partition table?
Mine looks like this;
Code:
~ # ~ # /sbin/sfdisk -l Disk /dev/mmcblk0: 1957120 cylinders, 4 heads, 16 sectors/track Units = cylinders of 32768 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/mmcblk0p1 16 1632511 1632496 52239872 c W95 FAT32 (LBA) end: (c,h,s) expected (1023,3,16) found (1023,63,32) /dev/mmcblk0p2 1760512 1891583 131072 4194304 83 Linux /dev/mmcblk0p3 1891584 1957119 65536 2097152 83 Linux /dev/mmcblk0p4 1632512 1760511 128000 4096000 83 Linux start: (c,h,s) expected (1023,3,16) found (1023,63,32) end: (c,h,s) expected (1023,3,16) found (1023,63,32) Disk /dev/dm-0: 0 cylinders, 0 heads, 0 sectors/track sfdisk: ERROR: sector 0 does not have an msdos signature /dev/dm-0: unrecognized partition table type No partitions found ~ #

I can't mount it as root, it tells me that I'm not root. So I try to mount it using opensh...

Now I think you can just use telnet and export your partitions and re-create everything properly and try instead of doing a reflash...

Your partition setup at least looks normal at the first glance.
Propably wisest is to do as thedead1440 suggested; boot in maintanance mode, and check if you can export and/or mount the partition. If not, then there is definitely something wrong there so reformat the partition and cpy the stuff from your rootFS /home there.
BTW, let me guess a thing
You might not have realised at the time this went wrong the first time, but I will tell you the symptoms you had at that time:
The cause of this was, obviously the fact that when the device cannot mount your mmcblk0p3 as /home/, it will do a fallback procedure where it sets up your home directory from /etc/skel and the new /home/hierarchy lives now on your mmcblk02p
----- edit -----
What I meant to add, the script responsible for the above stuff is "/etc/init/mount-home.conf"
And you could try to run /sbin/fsck.ext4 for your mmcblk0p3, just in case ith hepls

You might not have realised at the time this went wrong the first time, but I will tell you the symptoms you had at that time:
- Your device took a longer than usual to boot up
- When it finally booted, it looked like a fresh device; if you had folders on the homescreen now thy were gone and all icons were on one page. If you had a lot of SMS'es or messages all were gone.
- However, your MyDocs was intact, all your music/pictures/etc were just as usual.

Everything said already 
I had similar experiences during my ubiboot preparation. Repartitioned and everything looked good, but forgot to mkfs anew. Then had wrong size of p1 partition.
After zeroing the first 512 bytes of p1 I had totally starnge mounts!
After mkfs everything was okay.
So if you repartitioned manually and flashed without --no-preserve then you should really follow thedead/juiceme's advice.

All times are GMT. The time now is 14:06.
Instead, the stuff in /home/ is just under the home folder on rootfs.
