Hi, I'm new to the forum, I have also been scammed by one of the HK sellers on ebay.
Just bought a 16GB mp3/mp4 unit and tried to upload by music. It basically screwed up after it reached about 2GB and now I can't even delete the folders I created on it.

I have used the s1giveio on it and dumped mem to a txt file. Does not contain much but you ppl might be able to help me format the disk space and I can't do it using the 'Mp3 player utilities' it says something about 'disk encrypted'

My unit looks exactly like other member 'mdjava' pictures.
What I want to achieve is to get it report the actual size and then may be flash the firmware with something better.

Hope you ppl can help with this.

Use Google and look for a program called H2Testw_1.4. I also purchased a 16GB. This tool indicated 1.8GB or close to 2GB of actual flash memory.

I tried the procedure on my chipod that contains a ATJ2115F, TEA5767-VDLD60 and the flash memory of Samsung K9HCG08UIM-PCB0 which is 8 GB (64 gigabit).

I connect the player on usb but I'm unable to set the player into " firmware update mode".
I opened the unit, but don't know which pins to short.

Opening the unit was easy, reassembling was hell and you should take care that the buttons (metal parts) will not slide under their adhesive tape, rendering your player quite useless when it is assembled.

Pictures are attached !

The Reset pin on the AK2025 is pin (6), I don't have data on the chip you have in your picture.

Has anyone been able to extract and modify firmware from unit's with the AK2025 controller yet? This thread has been going for a while now and does not seem to be going anywhere.

here is mine ...... mine was also a ipod nano clone 16gb but was only 256mb heh bin and text included ..trying to find the data sheets on the ak2025 ..did find one but everything was replaced with dots

is it just a mater of writing soething in z80 loading into mem and executing it to grab the flash.. move so much rom to mem then read the mem??

coupla things I have found out about the player...

fake "touch shakeable" 4th Gen nano looking thing....with 30 pin connector.
s/n 6u734vmxyop[
model no. a1199emc / no. 2115

the bottom has a thin glued-on cover that hides 2 screws...

Also, to force ADFU mode, hold the Play/Pause / down button while plugging in USB cable ....
so no need to disassemble to short the memory chip....

Also, I've attached a zip file of the newest adfu driver i've found with the updated inf....you may hafta explore the USB ADFU if its not autodetecting and replace the ff## in the file ....

well i guess i can't attach a file that big....i'll at least include the .inf

email me with details....
