**Warning for those throwing caution to the wind only** I thought a dedicated thread might be handy for anyone interested in messing about with their 1073 player. Granted you may break it from reading anything here so if at all worried dont do anything mentioned in this thread. This website is an excellent resource in tracking various 1073 players. In particular given that there are many 1073 players on the market some with a better GUI than others but also release and forget players coming out from small resellers with no firmware support at all. I've basically been attempting to flash other 1073 firmwares to mine (AC Ryan PlayOn HD) with varying degrees of success and here are some of my findings. The firmwares most likely to work on 1073 players are ones which are similar in the first place in other words if the player can take an internal hard drive then the firmware from another 1073 player with an internal HD stands a good chance of working. 1073 players that dont have an internal HD option dont seem to work on those that do. Also the size of the flash ram in important as some players dont have the same amount so you cannot flash. Three things generally happen when you attempt to flash a firmware 1) The firmware installs normally 2) The firmware will try to flash then state a yaffes error (means not enough flash RAM) 3) The firmware has a built in checker and wont flash to other 1073 hardware (increasingly common on latest firmwares from certain players). In the event of 2 or 3 you can still flash other firmware back to the 1073. What firmwares work on the AC Ryan PlayOn-HD Datage HDPro Firmware is chinese/english stock Realtek GUI but firmware version is one of the latest builds v126.96.36.199 r2404. Also has several more options in Misc menu along with FTP support. Fantec MM-FHDL Stock Realtek GUI nice home screen, also has LCD orientation option, firmware is v7.0.3 r2228. IcyBox IB-MP305A-B Stock Realtek GUI, firmware version is v7.1.2 r2424 What doesn't work with playonhd Asus O!Play (yaffes error) Mede8er (firmware checker) Seagate Theatre+ (yaffes error) Labo 110 (yaffes error) E-Great EG-R1 (yaffes error) Eminent EM7080 (firmware checker) How to force flash 1) Copy the firmware onto a USB flash drive formatted with FA32. 2) Pull the power from the player and plug in the flash drive. 3) Press and hold down the players power button keeping it pressed. 4) Push in the power cable and keep holding down the power button. 5) eventually a blue firmware flash screen should appear after which you can let go of the power button. 6) The firmware flash is automated so it either works or doesn't. Happy hacking. Anyone else feel free to post their results or hacks they know off, may be useful for owners of abandoned RTD1073 players.
