Restore my MP4 digital player

I have the same problem as you! Did you find the solution?

Hi,
still no solutions.
Worse yet, since my drive is inaccessible for writing, I can't format it. Nothing to do.
Catch you later.

Hi everyone.
After several days of research online, I'm sharing the solution to restart your MP4.
The solution:
1-open the MP4 (remove the 4 screws on the sides) while it's off.
2-connect the MP to the PC (using the USB cable)
3-power on the MP4.
4-take a small screwdriver (the one used to remove the screws) and gently place it on the large black component on the first 4 pins of the electronic circuit.... this will cause your PC to detect your MP4.
5-after the detection of new hardware (AFDU).....install the default settings from the Windows files and that's it, your MP4 is back to life!!
See you and good luck!!!

Hello, I read your advice but unfortunately, it didn't help me much... I bought a digital audio player MP4 on eBay and it was working perfectly until suddenly it wouldn't turn on anymore. I understood that the problem might be due to the installation of a bad driver or firmware or I don't really know what. I don't know what to do. Here are the series I managed to find on my MP4:
ATJ2085H
F5238ABC61
SAMSUNG 625
K9WAG08U1A PCBO
HQFB 3.7VLi-042033
220mAh

I don't know what they correspond to. I tried looking for firmware with ATJ2085H but I couldn't find anything!
I would be very grateful if you could help me, I've tried everything and I don't know what to do, it’s only 2 days old...*
Thanks in advance.

Here is the radical solution to get a "dead" MP4 back up and running.

Not having received any response from you, I think my explanation was incomplete, so I'm delivering the solution on a gold platter, help yourself........

Still no solution, with the new school year it's depressing without music on the bus... but well
if someone has found a solution other than Abderrahmane's (because it doesn't work for me, but still give it a try!) thanks for replying!

Yes, the only solution I've found is to send the mp4 back to my seller so he can change it for me! Of course, I have to cover the shipping costs, but well, that's the only solution I could find.
Otherwise, my seller told me that out of the hundreds of mp4s he's sold, I was the only one to have had this memory issue.
My seller is Jacky 1368, what about you, Bago?

I wanted to send it back to the seller too, but I wondered if he would send it back to me! How can I prove that I sent it to him? I should send it by registered letter, but it would be expensive with the shipping costs, etc. He lives in Israel and doesn't speak French... Give me some news Gianni, I still haven't found a solution :'( Thank you in advance.

Ok, personally I trust this seller because I had a problem with my USB cable and he sent me one that wasn't the right one. I told him, and he sent me another one that still wasn't the right model, then I received the correct one with a case as a consolation gift, just to say that he didn't hesitate to pay shipping costs three times. Besides, I have nothing to lose by sending it back because for a memory problem like that, the only solution is to replace it (in my opinion). By the way, did you buy it on eBay? If so, you have nothing to worry about; you can declare it in the worst case, but the best solution is to inform your seller about the problem first. If you're having difficulty communicating, you can try the site https://fr.yahoo.com/?p=us (to translate from French to English or Hebrew, but that will be much harder lol). Good luck, and keep me updated. I haven't sent it yet; I'm going to buy 2 screws that I lost while disassembling it just before sending it.
See you!

Hello

I have a digital audio player mp4. I get a blue screen every time I start it.

Windows detects it, but it keeps asking me to update the firmware. (However, I don't have access to the disk.)

I have tried loading a firmware, but I still get a blue screen.

On the large chip, it says
SAMSUNG 610
K9K8G08UDA
PCBO
FU8043AA

Thank you in advance for your help.

Hello everyone

I have the same MP4 player. I had the same issue as you,
so I followed your advice to get the PC to recognize it. It shows "USB device not recognized" and not "adfu," and when I manually update the drivers by specifying the location of the adfuupdate.inf file within Windows, it says "The specified location does not contain information for your hardware," and the same thing happens when I use the drivers from the CD.

Thank you for your help.

Good evening,
I also bought a 4GB MP3 player on eBay from a Chinese seller. At first, it was working (very) well, but after I copied some files onto it, they no longer worked when I tried to play them from the player. After doing some more tests, I realized that simply copying a file onto the player made that file unreadable, even when I accessed it from my computer by connecting the player via USB. I would like to flash the player by installing a different firmware. I went to http://www.mympxplayer.org, where I found some logs that allow for firmware modifications but not for flashing, even though I'm sure it's possible... If someone can help me, I would be grateful. Thanks in advance.

Okay, it's nice, I eventually managed to find a log that flashes, I tested several firmwares but each time there was a screen issue, either blue or nothing at all, then I tested again with another firmware and there it is, the drama: nothing, meaning it's no longer detected by the computer, the screen is black then briefly lights up for 1-2 seconds and turns off, so I will try the technique described to do a hard reset, follow up to come...

Hi everyone, I have the same problem, except that no matter how many times I reinstall the firmware, turn off the player, turn it back on, wait, it won't get recognized.
So even for formatting, it needs to restart with the firmware. So I've added Aldebaran to my MSN contacts just in case I run into you; we can discuss it. But if anyone else has the same problem and has resolved it, you are welcome to help us because the last message was from November 5th, and we don't know if the issue is resolved.
Thank you

Hello, I have a Digital MP4 Player that I damaged by dropping it. I took it to my father's friend and he repaired it. Unfortunately, the screen has become blurry and I can no longer see anything. Please contact me to resolve the issue and let me know what I should do. If you know a repair person for MP4s, please give me their phone number and address.

Hi, I put my MP4 in recovery mode, it gets detected, I flash it, the first bin flash1.bin goes through normally, then it restarts. I format it (fat), then I pass the 2 bin flash2.bin. At the end, I put some songs on it, unplug it, turn it on, the screen stays blue but everything works, you can listen and everything.
I've tried this method several times but always the same problem. What should I do, thank you? I remind you that I have a Chinese MP4 1.5 inch.

Hello
So, geniuses, where have you been? I'm really disappointed. This morning I was waiting for at least a response, but there’s nothing. Buuuuufff, have a good day everyone!
(Just to remind you, it's an MP4 with a blue screen after the flash, but it works; the music plays.)

Hi

I have an MP4 player I bought on EBAY:
ATJ - 2085W
Samsung 616

It used to belong to my brother and he gave it to me, but it doesn't work anymore (I have a fixed blue screen at startup).

I have read all the threads discussing this issue and I managed to update the firmware (by short-circuiting) (3.5.37v2.1b FM.fw), and I formatted it with "MP3 player disk tools," but after that, I don't know what file to use as "dump.bin" because I tried one, and the player doesn't even start anymore :(

Thank you for your help

I almost forgot to say that at the beginning I synchronized and since then I can't delete the files I synced. Help!!!! It was enough to copy and paste, but well if someone could help me "repair" my mp4 that would be cool, thanks!
