avision Digital MP4 Player
 

hello, i am a new member that owns a avision Mp4 player that was quite troublesome the last few days.

while charging the player turned its screen white and stayed that way.
i browsed the internet and found numerous sites regarding this type of players, with all sorts of irregularities and allot of firmwares to fix them. after trying the reset button a few times i decided i should try to re-install the firmware.

it's not the first time i did so, i had a 'well' mp4 player fixed for a friend, but that one had the cd with the firmware, mine didn't even come with one.

And when trying to find the exact brand, i found out that avira was a fax/printer/scanner manufacturer that had nothing to do with mp4 players like mine.

i stumbled upon a site having a pic of my player (having 'MP4' written on the case instead of 'avision' tho) and downloaded the firmware to flash the player. it failed, nothing changed except the firmware version, with the screen staying as white as it could.

then, later on, after trying some other 1.8' screen mp4 player firmwares i found the S1MP3 site with what seemed to be my mp4 in the wiki site, at the mp4 database section.
They had an exact pic of it... with the 'avision' logo missing from it tho. they called it 'Freedata FD1505P4'.
I got the board ID they gave (JM_9312_V2) and using the extra info i got from this site i found a firmware called "FREEDATA_FD1505P4_9.1.52" that was presumed to be ripped from the player Freedata Player.

I tried flashing it and for a moment it seemed to work... till after the hourglass the menu appeared upside down at 180 degrees from its normal position.
The left and right buttons worked, but play/stop, 'menu' and 'vol' had no response.
It was motivating to get rid of the white screen tho...

I then tried a few more firmwares and at a specific one the player was no longer seen as a removable disk drive, but simply as 'usb device', with no driver matching it.
Panic was to follow. I browsed this site's forums, since they were quite useful, and i found the thread about 'how to recover a dead mp3/mp4 player' and did as it described. pulled the mp4 apart and played with a metal screwdriver over the chip's pins. it reseted when i touched certain pins, but it still failed to find the player as a disk drive like before or as an ADFU Device as it was described in the step by step tutorial.

while doing so i took some pictures of the player and submitted them in the gallery for people to see how it looks on both its outside and its inside.
After getting an accept from the admins they should appear in the gallery.

so, my question to you is the following... is there anything i can do to my player or is it completely dead?
I would like to know how i can get it to be recognised again if possible and if i manage that maby someone has a firmware for it?

Thanks for reading and I'm awaiting some help from you all, it would be really appreciated.

Get the board ID and the CPU, and also the display's part# if possible.

If you can get it into ADFU mode and hardware is not damaged, you will always be able to reload firmware on it.

Re: avision Digital MP4 Player
 

board contains all the following data:
SRX-Q2-91
Key: V0.3
2007-07-18
20080111

written on the front side, on the board part containing the 'play', 'next', 'vol' buttons.

not sure which chip is the processor, it has one on the same side with the screen that reads:
TEA5767
CE7537
06
IuG05412

and another one near the flash chip that reads:
*top part covered by QC PASSED sticker, can't take it off now since i'm reading from the pics i made yesterday when i reopened it. will open it later today if there's something else that would need to be written from this chip*

8G047AB 6GJ(bottom side)

tried going into recovery mode. it did restart as i touched the pins but no effect. will try today too.

*edit* not sure what you meant by display part but on the side of the screen there's a serial: H200801300003080821BHB

This is the closest match for SRX 91 firmware:

5767 is FM chip. The other square IC is CPU.

I suggest also trying SCC91 firmware, it seems to be related.

Do not short just any pins when trying to enter ADFU, only short together the DATA PINS of flash chip (see pinout). Anything else can cause damage.

Re: avision Digital MP4 Player
 

I finally got some free time to do the shortcircuit thing and get the player in ADFU Mode today. I flashed a few full firmwares and got the updater to see it in normal mode.
I got ahold of a cd with the player's firmware (someone had an identical one) and after making the player to be recognised (still with white screen) i managed to flash the provided firmware with a different version of MP3 Player Utilities, 4.18, that was provided with the cd.

Now, i got the hourglass going on like usual... but it just restarts over and over again before booting into the menu.
Also it's not recognised as a portable flash player by the pc. To reflash it i'd prolly have to re-enter in ADFU mode...

Any suggestions?

I checked the site you provided... i can't download anything from there... i don't know why.

But since i have the partial firmware on the cd would it be possible to make it into a full firmware with the help of another different one maby?
Where can i upload the firmware and maby the 4.18 version of MP3 player utilities?
If my player is dead i might as well help others not do the same mistake...

Yes, re-enter ADFU mode and try flashing again with the same firmware. You might have a bad flash chip.
