Modifying Series 11 (AK2025/ATJ2111/3/5) Device Research Thread

[jaf0]

turns out it's a 2.0gb///

if you're stuck at the ADMINISTR 00 MB thing,

use the disktool to create an encrypted partition to bring the drive down to "real" size...

I had to make the partition 5954 MB and then the thing showed ...

ADMINSTR 1968 MB ...

that was the max.

one way of telling is if both "disks" re mount properly in explorer.

if you get the error USB device had problems message .. your encrypted partition isn't big enough ....

YMMV

Hi Guys

Is this research still on going?

Please advise.

Thanks.

Here is my dump(see attachment). This dump is from my 2nd fake ipod (AK2025 16GB) which is still able to be detected by my PC.

For my 1st fake ipod (AK2025 16GB), my PC cannot detect this device and whenever connected with same USB cable, it keeps asking for USB driver. I tried ADFUUpdate.inf (from jaf0) but still no luck.

Please help.

Alright, enough BROM dumps for now. I think we have more than enough.

I still have a ton of Series 9 research and documenting to do.

This seems about the best thread to help me with a AK2025C nano clone.

When I press and hold the play button and plugin the usb, Windows sees the ADFU interface. I have loaded two different ADFU windows drivers and they seem to work. I have tried 3 different versions of s1giveio (v13/v14/the alpha version about which is dated 2009 and seems the latest). s1giveio just does not see the device. Device has an Apple icon on its display. Problem is with the internal flash; it was supposed to be a 4Gb device, but using the MP3 disk tool to test it, turns out its a 2Gb device. I resized it and it all seemed ok, but it would not keep its FAT32 disk layout; windows kept wanting to reformat, so maybe it needs to be slightly smaller? So I tried reformat under Linux, but from what I gather it needs to be encrypted. After the Linux reformat, unit fails to startup, but keeps rebooting. Guess its very unhappy about the disk format. So I want to dump its firmware and then try and fix its disk again.

Opened up the unit and it has the following chips in it:

Battery: 3.7V 140mAh Aman-302030
Main chip: AK2025C SA90QAC OIG
Flash: 1x Hynix H27UAG8T2ATR 16Gbit (2Gbyte; not 4Gb as per the sticker)
Radio chip: Comlent CL5767P
Goodix capacitive/touch sensitive chip.
Board: CB-2518-2-KEY CBD
FW version: 9.5.54.

Probably need a break from looking at this and to come back to it later, with a new approach

Also tried winxp-32 in virtualbox and win7 32bit. Also tried the s1res program to extract the firmware. Seems to be nothing can see the device, apart from Windows!
