Yes, believe it or not it is possible. You will need to download a 9.0.48 FULL version from the Firmware section, since it is NOT possible to extract it from your player at this time. Be sure it is compatible with your board and chipset. The way i figured out which one worked (RISKY) for my player was to download every 9.0.48 FULL file that was listed and flash it to my player until I found one that worked (dont flame me if you brick your player, I had no problems but that dosen't mean someone else won't). If you do choose this method and flash a firmware that is incompatible, your player will just show a blank screen. As long as it will still reconnect to the computer, even though the flash drive dosen't show up, you can still flash it with another file. ALTHOUGH, IF THERE IS NO FILE AVAILABLE FOR YOUR PLAYER YOU ARE S-O-L AND YOUR PLAYER IS A BRICK. After you find a compatible firmware file use the Firmware Modify tool from S1mp3.org to edit the language and battery settings. My file was set to default to Chinese and 1.5v Alkaline, so, I needed to change it to English and 3.6v Lithium. Save the modifications and then open it with S1res and change all the images you please. After you are satisfied, save the modifications and flash your played with the modded 9.0.48 firmware and enjoy being one of the first few with a modded UI on a 9.0.48 player.
Ohh yeah I'm new to the opensource idea with an MP3 player but have over 10 years of computer experience and have owned an onsite IT business for 8 years. As I figure out and learn more I will post my findings.

Just wanted to restate that the method I used could be VERY VERY risky. Try to avoid the method I used. most of the FULL versions of the 9.0.48 firmware have descriptions so try to go by that. Also, anybody know where they got the full versions from being that they can't be extracted????

ki4hou , usually the full versions comes from manufacturers or sellers. Or by using a similiar existing full firmware and merging it with your compatible dump firmware.

I had that suspicion. I just didn't know if there was another way i didn't know of extracting it from the player.

what do u mean by
"My file was set to default to Chinese and 1.5v Alkaline, so, I needed to change it to English and 3.6v Lithium" ?

can u change the amount of battery power ur getting or something?

sswajeta , some firmware modifying tools allows you to change the default settings of the player.

The battery setting does not affect the usage time significantly. tadad1 had ran a couple of tests with the various settings, but no major increase in usage time.

How do you take yours apart I have the same one and the FM Radio caused it to have a HARD ERROR now I can't use it doesn't even turn on.

I just got this thing today.

Can you send me a dump file or your full file or both because mine was pretty much DOA when I got it and I only got to use it for about 20 minutes and then it died.

Hi,

I also would like the full firmware please. I found the 9.0.48 full version but I can't quite understand if it's the full version or not. I uploaded to my MP4 but I still get a black screen when I turn it on. The strange thing is that if I plug it to my PC I can see my files and use it as a normal pen drive.

What am i missing?

mangi , currently your player lacks a working firmware. If those v9.0.48 firmwares do not work for you, then there is nothing much you can do about it. As the firmware extraction tool does not support any versions higher than v9.0.43 at this moment.

i ddid what u wrote but after it tells me that the fw success, it restart the ipod clone and nothing happen.. i'm finding myself with me old fw~...

why does it happens?

nirh216 , the "firmware update success" in the Upgrade Tool only tells you that the firmware has been successfully written into the player. It does not mean that the firmware will be compatible with your player.

what are ur serial numbers? maybe this full firmware can work on my player. probly not tho. but maybe

Erm...guys...I am new one on this forum but i'm not a NOOBE in modding and i say: I ALREADY THEMED MY 9.0.48 firmware 3 times
And...FULL firmware can be downloaded FROM PLAYER by ATJUpload4.0-Beta-its on japan but i can include PIC with instruction
I used s1res v2.1 to edit firmware
In quetions of uploading this programs(if you TOOOOO LAZY to find it yourself ) you can mail me at PaCTaMaH7@yandex.ru

Thanks for the information ki4hou!!!

At least it answers the question for me that my mp4 player has a blank screen because of incorrect firmware.

Yes, what;s the name of the software that allows you to change the settings of your language and battery? is it s1res?

Thanks for the info once again mate
