Need help on mount /dev/mmcblk0p1 on KT

[dove.young]

Hi! All

I am using a Kindle Touch. It's system is 5.1.2.

I was jailbreaked my KT when it was 4.x. But sometimes ago It was fallen on the ground and system was broken. ( system still running but all the fonts was gone. ) So I have to install an new system on it. Then it becomes 5.1.2.

I finished the jailbreak steps and usbnetwork steps mentioned in page

https://wiki.mobileread.com/wiki/Kind...:_NOT_5.1.2.29

and

https://wiki.mobileread.com/wiki/Kind...USB_Networking

Now I can login to my Kindle as root via ssh. But I am not able to mount /dev/mmcblk0p1. So that I am not able to modify font configurations in /etc/fonts/.

Here is my device information. Thanks in advance.

Why not using FontHack?

[ixtab]

If you're running in main, /dev/mmclbk0p1 is already mounted as /.

And no, don't try to "export" anything from the root partition to /mnt/us (by loop-mounting or so). First, /mnt/us is FAT32 and supports almost none of the important FS features. Second, this is almost certainly going to fail, because /mnt/us becomes inaccessible to the Kindle when it is plugged to the computer as a USB drive.

Just don't do it. Make your changes from the ssh command-line instead.

It COULD be done by booting diags_ssh, mounting mmcblk0p1 from SSH, then exporting USB from the diags menu. Windows can be confused about symlinks if finds there, and it would be a bad idea to make changes from Windows. As ixtab said, there are better and safer ways to do what you want (i.e. SSH).
