my dvd player won't boot or play discs after me failing to upgrade the firmware. does anyone know a way of rewriting the firmware to the chip when it won't boot. all i get is the blue philips screensaver. i've noticed that there's no rs232 connection to do it like on the old players.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

You may have bricked the player. This is why firmware upgrades are VERY dangerous and should only be attempted if you have a compelling need for them. If it's under warranty you can try to get a new one. If not, you'll either have to pay for a repair or buy a new player. Honestly it's probably cheaper to just buy a new player. Learn from whatever you did wrong in the upgrade and don't do it again if you attempt this in the future. If you can't get the player to boot enough to try to redo the firmware upgrade, then it's either time for a repair or a new player.

Can you take a good photo of the mainboard? I saw the mainboard of the BDP2600 and at first it appeared that there is no rs-232 on it but it's actually there, the connector is just not soldered to the board. If rs232 is there it should not be hard to unbrick the player (you will have to use an RS232<-->TTL converter, 3.3v. levels.).

Kind of a moot point there, marlboro_,man. His player won't boot at all, so getting RS232 working won't solve that issue.

Huh?...What? I said that the bootloader is obviously functional, otherwise he wouldn't see any blue philips screensavers.
Even if player does not show ANY signs of life, it can still be unbricked, as long as the bootloader is intact and TTL communication port is present on the mainboard. But you wouldn't know anything about it, would you?Last edited by marlboro_man; 1st Dec 2012 at 19:18.

i've found a connector thats 4 pins, but i thought rs232 connectors were 9 pins. its bottom left corner.

how do i use the emulator to transfer the .bin file and which is the best one to use? thanks.

The mainboard is supposed to have TTL communication ports. It should be connected to a computer RS232 port through a TTL<-->RS232 converter like this one.
I don't think this is it. Those MT85xx mainboards have 2 TTL ports - "front end" and "back end". The one that is usually located near the optical drive connectors is the "front end" port. We need the "back end" port.
Jump that bridge when you get there -
i have a ttl lead that i used to unlock mobile phones. what do i have to type to transfer the .bin file to the blueray player?
-
i have a rs232 lead with an in line chip powered by a 9v battery that converts to ttl. how do i transfer the file to the blueray player?
-
i am using putty like you said. the lead is working but im not receiving anything on the screen from the blueray player. ive selected com session and the settings you said but what terminal type and id should i select? ive touched the rx wire with my finger and i'm receiving characters on the screen, so the lead is working ok.
-
i still can't get anything to come up in the console unless i touch the rx wire, then i get random text. i have connected rx wire to tx on board and tx wire to rx on board and gnd to gnd on board. no joy! are you sure that you can't connect to the lan connector?
-
I am sure.
I see 2 possible reasons why it does not work:
1) Wrong TTL port. Unfortunately, I don't have a service manual for this player, so there is no way to tell.
2) Your self-powered converter use 5v. instead of required 3.3v. I successfully used a MAX232-based converter - I connect all 4 wires, so it is powered from the mainboard.
