I tried with two version!
One is noticed that Unknow flash type, another is noticed : "Read or write device information failed! Please exit the program and check if device in connecting"

How should I do now?
How can I reset the chip!
Please show me in details!

khang, Instuctions on how to reset your chip are here
http://www.mympxplayer.com/viewtopic...=asc&&start=30
After you reset your device you will need to upgrade it with a full firmware these are very hard to find. I have found another version of 3.2.13 that appears to be a copy from a CD so this may be a full version. There are 2 one for a player with FM Radio and on without.

If you are going to open your player and reset your chip I suggest you download these firmware as you will need them after you reset your player.

Tadad1, I see that there are many links and Attached files, I don't know which one is need for me!
Please give a name of those!
Thanks a lot!

Have you ever Dissassemble any player and reset the chip , tadad1?

Have a look on this!

My player is in recover state and Windows can recognize it!

So, may I skip the step 3,4,5 ????

Please help me because my English is not good!

khang, I have never had to reset a chip as I have never killed a player. My concern with your situation is that although your player reports that it is in recovery mode the Firmware Upgrade Tool is not reading the device.

Your Quote: "When I chose Recover firmware button to start the recovering, there is a error message box:
"Read or write device information failed! Please exit the program and check if device in connecting!"

If the upgrade tool cannot connect with the player it cannot upgrade the firmware. The only thing I can think that will fix this is to reset the chip.

To download the full firmware on the chinese site there is a large green button under the description.

My player needs a full firmware for recovering!
Is it included in the CD-ROM driver when I bought it!

Tadad1, thank you very much!
A last question. Is a full firmware included in the CD-Rom Driver which accompanied with my player !

khang, You will have to check your CD it will be a .bin or .fw file. Not all players have one included on the CD my player did not have one.

Heym Tadad1!
I checked my CD driver, there is a folder FW (maybe FIRMWARE) with many file .bin, and .fw.
I tried each of them, but the Upgrade Tools noticed that "Unknow Flash Type"

huhu, I must have some internal operations...
Anyway, thanks a lot!

Hey, Tadad1!
Why is my player recognized by WIN (item in the system tray), but I don't see its driver letter in WIN EXplorer!

So, I can't extract and repair the flash!

I really must reassemble it for reseting chip!???

khang, connect your player to the computer and then right click on My Computer and select Properties. Go to the Hardware tab and select Device Manager. Look under the heading Disk Drives and see if there is an entry for GENERIC USB DISK DEVICE, if it is there right click on it and select uninstall and uninstall the driver. Then choose Action from the toolbar menu and select scan for new devices. If Windows finds your player it will install the drivers for it and then you may be able to connect to it.

If you are unable to access it then the only thing I can think of is to reset the chip as we discussed.

My mp4 player is recognized as ADFU device, but its driver letter is not appear in WIN EXPLORER!

I connected in USB port and run Upgrade Tool program, it noticed that " It is recover state, choose a firmware file for recovering"

I tried many firmware file (.bin,.fw), but it always notice that "Unknow flash type"

What should I do?

Now, it's always in blue screen!
My MP4 player is 256MB, Flash: WS-3.2.13
Please help me!!!!
I really don't want to open it and reset the chip!
:(

Khang, even though you have the backup firmware on your cd...which you said doesn't work... try downloading this 3.2.13 firmware from s1mp3.org and see if you can at least get it out of recover state. Then you'll at least be able to save files on your player.
Here's the link:
http://s1mp3.org/files/firmware/fw_f...orig_3.2.13.7z

...if you get it out of recover state, then try upgrading with any of the backup firmware files you said you found on your on cd.

Just in case you're having trouble extracting the 7z firmware file from s1mp3.org, you'll need to download and install the 7zip file extractor from the tools section of this website.

If the firmware I gave you the link to doesn't bring it out of recover state, try other 3.2.13 versions from s1mp3.org or even 3.2.16 should do.

Let us know if you need more help.

I tried, but the Upgrade Tools Program is always noticed that "Unknow flash type!"

I tried to run UCheck (posted in our forum), but it can't be recorgnized!

How do for this situation?

Huhu, my player always like this!

:(

Khang, here's another suggestion that may or may not work.

Since your player shows the loading hourglass screen, your player still may have the firmware on it (though it may be corrupted).

Try reinstalling the mp3 utilities...this helped me once. My upgrade tool was acting crazy but reinstalling it fixed the problem.

If your mp3 utilties cd has many .fw and .bin files, try using the s1res utility to see pictures of the firmwares and recognize the firmware that was in your player originally.

If that doesn't help, then try extracting the corrupted firmware that is on your player now and use the repair feature of the s1fwx tool.

Then after reinstalling the upgrade tool, try recovering with the repaired firmware.

Hello there everybody.
wanted to say thankyou much for the recover guide on pg 2 of forum.
My mp4 gone dead for 3 month and couldn't find recover guide for MP4 anywhere!
very lucky my player look same as picture in guide.

I finally fix my player with ver3.5.35. my only problem was that player die and computer no recognise.


Thankyou's to everyone on this site. great help and very good site.

Thank you again.

ash_mp4, good to hear you had some luck with your player. If you are able to outline the steps you took to recover your player it may help others do the same. Thanks for your post.

:)

I did all of the work you adviced, but it's still dead!

I tried all of my FM files, but there isn't any file with the logo in the same with my original logo!

I tried to check my player with CheckUdisk but it is not recognized!

Arish, When your player had been died, can it be recognied in Win Explorer ??? (with its driver letter)

My player is recognized as a ADFU driver, but there is not its driver letter in Win Explorer!

I think...no way!!:( :(

Khang, if it's recognized as an ADFU, then you won't see the disk driver in Win Explorer.

You'll need to get it out of recover state before you can access your player's flash disk...but you said you're having trouble with the upgrade tool. Try upgrading in another computer if you can and see if you get the same problem while upgrading.

Maybe your seller just handed you a random mp3 utilities cd so....like you said...the firmware on it is not the original firmware that your player came with.

I am afraid you're gonna have to fish for the correct firmware on the internet.

Good luck with that

Hello there tadad. Thankyou for response. I just use basic steps to recover player: I follow the guide on how I have to short chip from here:
http://www.mympxplayer.com/viewtopic...=asc&&start=30

Then i match my board with fw & download 3.5.35 fw on s1mp3.org & upgrade my player inside upgrade tool. Then my player is good to go.

Thankyou to all once again.

hey, arish!
Will my player be out of the recover state if I find the right firmware??

I will open it and get the board ID, maybe it's easier in looking for the right firmware!

I think it's the only method to take my player out of the recover state!

Could you help me find the right firmware if I can get the board ID of my player!!!???

Sorry if I bother you!

Khang, I'll try my best to find the correct firmware for you if you get the board id. Hopefully the list of firmwares on s1mp3.org matches your board.

If you're still having trouble with the upgrading tool, then I think you're gonna have to short circuit your player. You said it gave you a message like "read information failed." Most likely, the upgrade tool is having trouble reading the firmware that is currently in your player because it may be corrupted...so it comes up in recover state, tries to recover it, and causes further errors.
When you open your player to get the board id, short circuit it and then try to upgrade with any of the firmwares that you have tried previously. Try with one that didn't give you the message "unknown flash type." This should get it out of recover mode and you should see the disk driver icon in win explorer.
Look here if you need a guide to short the pins:
http://mympxplayer.com/viewtopic.php...=asc&&start=30

Once you get the upgrade tool to work fine, then proceed on to get the correct firmware and upgrade with it to completely fix your player.
Keep trying to contact your seller though.
Post the board ID and I'll see what I can do.

Hi, Arish!
I bought my player in my country (Vietnam), but I have been in Korea, so... although it is still under warranty!

I am trying to contact to the seller for getting the board ID or FULL FIRMWARE!

Please keep in touch with me!
Thanks a lot, Arish!

...no problem, khang, I am here to help.
Good luck getting that firmware from your seller.

Hi every one,, I'm newbie here, hope you show me the right way to use this incredible forum for good in order to let anyone who's in need for such info,,
I'd like to add something i passed with by trial on my Astra 512 MP3 Player: ATJ2085 chip to force the system to accept my dead mp3 as a flashdisk,, it is to short the Capacitor which located near the SAMSUNG flash chip while connected into the USB,, I tried this way many times and it works to force the MP3 to enter ADFU mode.
here's a small pic showing the capacitor location,,

P.s:
I don't recommend anyone to experiment this trick as it may harm the rest of your beloved MP3's :? .
take care, and thnx in advance.
