Request: Atari Flashback 9 Boom firmware backup

[lamasutra]

Hello, I'm looking for an Atari Flashback 9 firmware backup.
I need to replace corrupted kernel partition, but I'm unable to find it anywhere.

If you have modded your console and can access it using rkflashtool, can you please make one and post a link ?
Some people have reported bricked consoles after applying update too. Firmware backup can help them solve the problem.

I have allready contacted several people including atgames, but no one has a backup or not replied yet.

thank you for help
 

Meanwhile you can try my old hack of Dreadnaught Factor game for atari 800.

I have a modified BOOM but I don't know how to extract the firmware backup. If you have a tutorial on how to do it I’m willing to try.

Thank you

First of all we have to determine status of your console and what is your operating system.

1. Do you have connected usb traces on console's main board or soldered connector into usb holes ?

2. Are you using Windows or Linux ?

I will prepare tutorial based on your answers.

1) I'm using the CFW of this topic: 

No hardware changes were made.
2) Windows

Console modding
I have to discourage you from console modding, If you want to preserve warranty or If you are not familiar with soldering.
I will describe you how my console have been done in modding tutorial.

 

Overview of PCB

 

Modding Tutorial
You will need philips screw driver, tweezers, soldering iron with very small tip, solder, Cu wire and multimeter.

1. Open your console. Use philips screw driver. There are 5 holes.

2. Prepare 2 tiny Cu wires - apply solder on them.
3. Solder wires to pads. Tweezers surely comes in handy.
4. Measure conducitivy, there have to be no short circuit between pads, gnd or vcc.

 

Alternatives ?

There may be alternatives, which doesn't require soldering at all, not so reliable, but may do for our purpose.

I can suggest using USB data cable from old mobile phone, which you can cut off on phone connector's end.
Use GND, D+ and D- wires (black, white, green are standard colors). Prepare tip of each wire, you can put solder coating on them so they can be inserted into holes and do not slip out easily.

You can also use scotch tape to fix wires in position. Double check conductivity with multimeter, so there is no short circuit between wires and no short circuit to pcb components.

Let me know, If you try to mod your console. I would prepare dumping tutorial for windows.

OK, I know how to solder. There is no problem in this part.

Hello all.
I have great news.
I bought another console for 500CZK (25USD) and managed to dump nand and repair my broken one.
I can confirm joysticks are working and can play games again.
You can pm me for those partitions or be patient, I will upload them to some cloud as soon as possible.

You are a good man for solving your own problem and still taking the time to share your results. So that you can help others that may encounter the same problem.
Thank you for doing that.

I have reuploaded it here, for posterity:

Seems like awesome work!!

 

I have a bricked AFB9 too…

 

Being somewhat of a Linux noob (but good with a soldering iron), could someone please step me through how to reflash my AFB9 with the ar3050.zip file above?

 

Many thanks!!

I recall I have used https://github.com/linux-rockchip/rkflashtool in linux. All main distros should have the package. For ubuntu:

sudo apt install rkflashtool

It can be reflashed in windows too with appropriate tool.
