I first deleted many things in my media partition to have space, then I did the backup thing

cnegrete@cnegrete-laptop:~/Downloads/Pre/SHR$ make backup

Then I did the resize thing
cnegrete@cnegrete-laptop:~/Downloads/Pre/SHR$ make lvm-resize

 Unmounting /tmp/var

Then I restored my media data
cnegrete@cnegrete-laptop:~/Downloads/Pre/SHR$ make restore-media

I flashed the kernel

I got my Image that I had downloaded earlier and flashed it to the Plus

That's it, I just connected to reboot

cnegrete@cnegrete-laptop:~/Downloads/Pre/SHR$ novaterm

root@palm-webos:/# tellbootie
novacomd socket was closed prematurely

There, remember that I had bootr from the other installation, and I didn't install it this time
