I've flashed fw-taobao.bin, better than peal_custom.bin, but backlight set has a few difference.

Hi mirecek1965,

looks like your friend flashed a wrong custom fw. If there is no backup of the original fw - bad luck.
All you could do is: try flashing all available 240 x 320 fws an hope one will work...

A second thought:

is there a label / barcode / sticker on the box with a text like "POF16", 21334" or something like this?

looks great! ;-)

some issue with the backlight.
setting 1 to 16 works like it should. setting 17 to 21 is like 12 to 16. I'm not sure if I get full brightness.

Hmmm...
Can't find anything unusual. Does brightness adjustment work correctly with the original fw?

You are right. It is exactly the same with the original FW.
Thx! Now i will try to control the display from my openWRT router!

/Josef
Re: dpf-ax: unsupported dpf - requests
October 02, 2013 03:25AM
Okay. So nothing I can do.
I will add this dpf als "clas_olson_2" and add a comment about the - partly - broken brightness control.

Hello,

I have a DPF here with 320/240 resolution, I tried to retrieve the information
regarding the DPF with identify.py via pythobn.exe. It says :

Looking for firmware...... : not found
This is no known firmware!
Sorry no matching pdf found.

I did make a binary dump, can you please mail me for the bin-file and help me out?

Thanks in advance and with kind regards,
Dovi

Hi Dovi,

looks like this is not an AX206 based DPF.
To be sure, please upload your firmware dump. I will have a look.

Hi! I have a keychain picture frame that i bought on Media Markt in Sweden, it's called COBY DP151 (151BW). And it does not seem to have any matching Firmware.

Sorry, no matching dpf found.

But the following model has a partial signature match: carrefour_bfv151.
This firmware MAY work for your dpf.

I tried fw_carrefour_bfv151.bin but it is very, very dark, graphics almost invisible and it almost seems inversed (dark is light, light is dark). Also, it's rotated 90 degrees counter clockwise (but I find that orientation better).

I tried to attach stock firmware, but even when compressed it's 1.2MB, so I link to it instead if okay?

@superelchi

Yeahhh! Thanks! Only backlight seems a bit odd... But I don't think the original firmware even let me control backlight (only contrast). :)

What can I do with display now?

"Odd" in what way - brightness not getting brighter on each step / not working at all / ... ?

Have a look here: lcd4linux.

It goes up and down, and I do not see any real pattern in it's behavior. Not much difference between steps either. Even at setting 1 it's well lit.

Subjective list:

1:
2: up
3: up
4: up
5: up
6: up
7: same as 6
8: same as 6
9: slightly darker than 1
10: like 1
11: like 2
12: like 11
13: like 11
14: like 11
15: like 11
16: like 11
17: like 9
18: like 11
19: like 11
20: like 11
21: like 11
