    Dear Snakehead,

    Thank you for spending time on this.
    I know little bit of electronics. So I taught I would like to fix this by myself. Would like to learn more by getting it done hands on J

    What I could de-code is, there is a Boot Flash Chip (29LV160TE) in TSOP 48 Pin package. I do have the Firm ware on a CD. Would like to know if I remove the Chip & put it in an EEPROM Burner & Burn the firm ware will it work ? Or does it have dedicated Boot Loader ? Any idea ?

    Thanks,
    Swami.

Phillips BDP5100 not play BD (unknown disc) but DVD read and play no problem How can i do pls Help me ????


The player detects that the discs contains unauthorized copies of movie titles.

The disc is with a new format which is not yet supported by the player. Some newly released Blu-ray titles in the market apply new disc format which did not exist when the player was manufactured. This leads to playability problem with these discs. This is not a defect of the player and can possibly be solved by firmware upgrade.
The Philips technical team is constantly working on the firmware development to enable the player to play such discs. Installing the latest firmware in your player helps to ensure optimal playback performance. Please visit the support website of your player regularly to check out new firmware release.
Before you update, read the Firmware Upgrade Readme File on the Software and Drivers page. It contains information on playability resolution on discs of particular movie titles.


If the latest firmware is installed in the player and only one disc can't be played, there may be some problems with the disc. It may be defective/scratched.
Another possibility is that the lens of the player is dirty. Try cleaning the disc and the lens with a lens cleaning kit which is available at electronics stores

Can i upgrade my firmware


Yes it can be upgraded if new firm ware is out and only at the Vizio product support site, just enter your model number and will see if any new firmware is out for the player, you will then burn that to a disk and then follow installation instruction, the process takes about 30 minutes to complete if new firmware is available..

IC25n020ATMR04-0 firmware how can i remove the firmware and replace it


certain utilities from salvationdata or acer lab can help one do a firmware back up and restore, also certain hard drive companies like seagate and wd have firm ware backup and restore utilities,hitachi has its firm ware saved in three places on the harddrive in the SA areas as SA A SA B AND SA C. one has to have hdd hitachi from salvation data to back up firm ware , which i feel is an expensive affair. or just go to a recovery guy and ask for firm ware upgrade done by salvation data or acer equipments
if the charges are exorbitant , let me know the firm ware of your hitachi drive and i will try to give it to you. pm me if you are not in a position to back up by any of my recommended methods

You probably have Winders Media Player 11. If you can find another computer that has WMP 10, you can use that computer to do the firmware upgrade, then go back to the original computer. Thingsa should work fine. Otherwise, you need to unistall WMP 11 and WMP11 runtime. Another case of Billy messing us up. And don't even get me started about vista....
