I have a got this problem, 'Memory read-only. Cannot write to the device'.

The problem is like i have created partitions, but with wrong block size.

I have the 8GB appln install space eMMC. With that, my partition table appeared to be
Device Boot Start End
/dev/mmcblk0p1 2 688258
/dev/mmcblk0p2 688258 950401
/dev/mmcblk0p3 950402 974977

Instead of usual

Device Boot Start End
/dev/mmcblk0p1 2 884865
/dev/mmcblk0p2 884866 950401
/dev/mmcblk0p3 950402 974977.


So I carried out a partitioning like

n
p
1
First cylinder: 2
Last cylinder: 600000

n
e
First cylinder: 600001
Last cylinder: 688258
n
First cylinder: 600001
Last cylinder: 688258
t

Is there a problem due to this? And i now cannot copy any files into the eMMc or even move within. Shows memory read only or input/output error- when done from xterm.

And also when tried to untar the NITDroid archive, the same result.

Any suggestions friends?
