Read-Only internal storage?

Hi All,

(I've read tons of Threads here, but not yet found a solution).

My Galaxy Tab 10.1 is useless right now as it cannot write to internal storage.
Lots of apps crashing on use and doing a factory reset from the recovery menu does not help (Tablet is in exact same state aon reboot).

So, I've been using adb:

C:\Program Files (x86)\Android\android-sdk\platform-tools>adb remount
remount failed: Operation not permitted

Here's the mount information from shell

shell@android:/mnt/asec $ mount
rootfs / rootfs ro,relatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
debugfs /sys/kernel/debug debugfs rw,relatime 0 0
none /acct cgroup rw,relatime,cpuacct 0 0
tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0
/dev/block/mmcblk0p4 /system ext4 ro,relatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p5 /cache ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p8 /data ext4 ro,nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc,discard 0 0
/dev/block/mmcblk0p1 /efs ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0
/dev/fuse /mnt/sdcard fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0

So, I've tried to mount manually from adb shell:
shell@android:/ $ mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mount: Operation not permitted
shell@android:/ $

shell@android:/ $ mount -o remount,rw -t rfs /dev/block/stl9 /system
mount -o remount,rw -t rfs /dev/block/stl9 /system
mount: Operation not permitted

But, I have no SU command:
shell@android:/ $ su
/system/bin/sh: su: not found

I've got the su binary from downloading off aforum, but I cannot copy that up either (even to seemingly writable mount points)
C:\Program Files (x86)\Android\android-sdk\platform-tools>adb push su /cache
failed to copy 'su' to '/cache/su': Permission denied

So then I followed a guide I found linked on a forum to get the Tablet Restocked to factory settings.

However, when I try to write via Odin, I get an error message on the tablet in Red:
Bct_sync_Odin: Error to NvBuBctUpdate![err:0x140005]
DownloadPartition_Odin: Error to Bct_sync_Odin![err:0x140005]
Tegra_Nand_Write: Error to DownloadPartition![err:0x140005]

Is my tablet bricked ?

Likewise. htc amaze4g running ics 4.0.3, non-rooted, w/32Gb ext sd card: was listed in Settings/Storage as unencrypted read-only; so I backed everything up to my daughter's Mac using CCC, then encrypted the ext sd card... then it shows as encrypted in settings but is functionality invisible, AND the (internal) Phone Storage is listed as read-only.
I thought, maybe they both need to be encrypted, so I did that, but no writeable storage is available on my phone... just useless, encrypted space. :(
