PRS-T1 How do I resize the system partition?

How do I resize the system partition?
I tried the method on the wiki but it doesn't work.

Everytime I try the command "mount /dev/mmcblk2p4 /mnt/sd/my_test" it gives me the error "mount: mounting /dev/mmcblk2p4 on /mnt/sd/my_test failed: No such file or directory".
If I try to create this directory with "mkdir -p /mnt/sd/my_test" I get the error "mkdir: cannot create directory '/mnt/sd/my_test': Read-only file system"

Has anybody successfully resized their partition and could help me with it?

there where errors in the wiki, should be fixed now.

but you do not seem to have enough linux knowledge, otherwise you could have fixed this yourself. this is not to offend you, but please take care - you can completely brick your T1 on a root console if you don't know what you're doing!

I may not have enough linux knowledge to do this by myself but enough to know how to not brick my reader.

Btw, there was still an error in the wiki:
It was "mount /dev/mmcblk2p4 /mnt/sd/my_test" but it should be "mount /dev/mmcblk2p4 /tmp/sd/my_test". Also it read "tar -cvf /mnt/sd/my_test/system.tar" but it should be "tar -cvf /tmp/sd/my_test/system.tar".

The last part didn't work - it gives me this error:
"tar: empty archive"

One more thing - isn't it posible to create an image of the old system partition with dd, mount it and copy it's contents to the new image?

Why? What's wrong with it?

unwohltaeter · 12-04-2011, 08:17 AM

It says "no such file or directory"

uboot · 12-05-2011, 03:51 AM

so, /mnt does not exist? well.... change it to /tmp or do a mkdir /mnt

unwohltaeter · 12-05-2011, 12:15 PM

Finally got it to work...

uboot · 12-05-2011, 05:20 PM

great

please update the wiki if you have spare time...

Regarding dd - if it exists on the T1, it should be possible to dump system with it...

Another way to dump system partition is using ebook_msc-Tool included with minimal-root.zip. But haven't tried that yet...

Hi,

So if I am able to dump system partition to T1 internal SD memory, will this free up room for additional applications to be installed?

I already tried the Resizing Data Partition by using Link2SD to no avail. I am pretty sure I did the procedure correctly. Have there been a lot of people successful with this approach?

I had a whole big bunch of apps installed (3-4 times as many than would have been possible with the very limited space) and linked. No problem.

Hi,
I'm trying to follow the wiki instructions for resizing the system partition (more sofisticated way): do I need to enter recovery mode, or I just need the normal system + adb?
thanks

You need recovery mode...

You cannot mount/umount/resize nothing while you are using it!

m3l7d0wN · 01-23-2012, 08:17 PM

yeah, it works and seems easy :P tomorrow I'll try to resize the partitions

vietchovui · 01-23-2012, 10:38 PM

I tried to free up the system disk with link2sd and app2sd but failed. Can anyone write a step by step wiki about this? Regarding linux, I have no knowledge but with a very detailed wiki I'm able to follow.
