I can't backup my firmware

I can't backup a firmware! :cry: :roll: :cry:
To better explain my problem, I've created a presentation.
Please view, it will not take a lot of your time! :idea:
(But I was making it all the morning!)

So, what do you think? :roll:
I guess I'm not the first person who have tried to do it... :roll:

hi WIZARD
Can you post a picture of your player?
I need to know what you are trying to back up, can't see your presentation, I don't have powerpoint!

cheers knob

Sorry, I had to take into consideration that you may not have.
I've transformed my presentation into 9 PNG pictures you can open.
Please download this archive with pictures:

And there is the photo of my MP4 player:

Nice, yes?

ops: :P 8)
It's a Rockchip, 26XX series.
Don't sure about model but guess it's RK2608 because of it's functions and description.

Sorry to say there is no way to backup series 26xx rockchip players.

dancemammal's mp4 editor also doesn't have a firmware extract option.

If your player supports rock games if would be possible to create an extractor using the .rkp assembler from benny, but it would need someone who is good at assembler programming. :idea:

I know Pascal language only.
I'm studying, so I haven't time to learn something like Assembler.
My friend know, but he's studying too and haven't MP4 player,
so for him there's no reason for programming on Rockchips.
I've tried to persuade him to buy player like mine,
but without any result. :roll:

Know FirmwarePuller was created for RK27XX.
Maybe it's possible to remake this program for RK26XX... :idea:

Also I have an another IDEA... :idea: :idea: :idea:
We can juct make the FULL image of player's hard drive
using one of some special programms for that purpose
and then just try to find Start and End adresses of player's firmware...
It's completely safe. It would be easier to find if backup a player's files (music,pictures, etc.) and
then delete all the visible folders (which we can find in explorer's window).
There will be no files except the hidden firmware.
The first bit "1" will be the Start adress, and the last - the End adress.
Then extract all the bits between the Start and End Addresses
(our hidden firmware) to a new file "Firmware.bin" and
rename it to "Firmware.rfw".
THAT'S ALL !!! :wink: :wink: :wink:

P.S. It would not be hard to guess about the way how to restore firmware -just need to remember start adress from the last time.
Add more automatic - I think this way will work,
but to faster do backup/restore operation we need program
which will do all this automatically.
Maybe Dancemammal will help - he has a big expierence in programming...

Also I would like to suggest that this way will be working not only with RK26XX, but with the all kind of players.

Knob, Dancemammal, please tell me your opinion about all this. :roll: :roll: :roll:

dancemammal's mp4 editor is not for 27xx series, it is for 26xx series players. :wink:

The problem is the firmware on 26xx series players is hidden from windows.

A specially made .rkp would be able to "see" the firmware, so it would be possible to extract using a .rkp utility written to run from the game menu, this would only be good for players with the GAME option. :idea:

If I was good at assembler I would write one myself, but sorry to say I'm not that good at coding.

It was your opinion about Dancemammal's editor. :|

And what's about my IDEA? :idea:
It would be easier to do all these operations manually,
or write a program that will do it automatically,
than to write program for Rockchip!
Also, even if you will write it, I wonder if Rockchip will copy firmware,
because all system files embedded in firmware would be in use!
My method is universal (suits for all the players) and perfect. :idea:

So, what do you think? :roll: :roll: :roll:

I you have a look, "Wire", has posted some source code, you will have to go to his site to get to the sourceforge svn, download the source and have a go.

Its in straight 'C' with some assembly, but he seems to have done most of the hard work.

I would have a go myself, but work takes up all my time, might have another go when I have some time.

Regards
Dancemammal
