truco para cambiar de dingux a opendingux sin formatear la tarjeta

[deadfunk]

pues es eso, bajan el opendingux(buena pinta, regular funcionamiento , hasta el momento . renombran la zimage, el roofs, pero a borrar las antiguas, el boot pide que esos archivos esten en el comienzo de la tarjeta, para esto hay que reacomodarlas, para esto :

1) bajas http://www.kessels.com/JkDefrag/JkDefrag-3.36.zip
2) ves con que letra esta tu tarjeta de memoria - por ejemplo "H"
3) ejecutas cmd, pones cd espacio "directorio copiado desde la ventana donde esta jdefrag" enter
(y usando la letra con que tu pc reconocio tu memor¡a pones):

JkDefrag.exe -a 5 H:\zImage H:\rootfs.bin
y yasta, se deja de pegar en el logo y evitas tener que formatearla(con la de musica que tengo en mi memory XD)
saludos y dejo el original sacado de internets.




Safe zImage/rootfs replacement (solves freezing at Dingux logo)

As many of you already know, and as Dingux troubleshooting guide says, it's important to put zImage and then rootfs files as the very first files on the card.

But what to do if you want to replace the kernel or rootfs image ?
You may just override these files with the new ones, but if you do so - there are chances you won't be able to boot Dingux again,
and you will have to backup files, reformat the card, and only then do the things in a clean way - copy zImage, rootfs and only then copy back all your files you backed up.

What a mess and what a waste of time !
Copying all these gigabytes from and back to card may take a whole hour !
Not to mention a frustration if you have to do that again and again.

Here comes the solution. Instead of all this "I like to move it move it", we will just move zImage and rootfs to the beginning of the disk:

1) download http://www.kessels.com/JkDefrag/JkDefrag-3.36.zip and extract jkdefrag.exe from it
2) find out the drive letter your Dingux card uses - let's say, H:

3) from the directory where you extracted jkdefrag.exe run the following command line (using the appropriate disk drive letter):

JkDefrag.exe -a 5 H:\zImage H:\rootfs.bin

Now put your card back into Dingoo and/or reset it - it should pass the Dingux logo screen and boot successfully.

Some technical info:

- There are people that don't experience this "stuck at Dingux logo" behavior, and I believe it's connected with the size of the card they are using.
With my 8G card I cannot boot every time I replace zImage.

- I used WinHex to see what happens when you replace or add new files.
I erase a number of files sitting at the beginning of the disk, then copy new file into it and - voila - it doesn't reuse the just freed clusters - but puts the new file somewhere else.
