Trio TCH1643
cenobyte:
The player is not showing up under lsusb on my linux box any more, so I will try to update it via the XP machine now. If not I will try to open it (I am guessing it involves shorting of pins?)
Post Merge: April 10, 2012, 02:33:35 AMI plugged the Trio into the XP machine and downloaded a temporary copy of winimage. I opened the Archos image with winimage and used the 'inject folder' option and tried to add everything from the Trio firmware. Again, I was told there was no more space in the image so I am not sure how to go about copying files into the image without running out of space. After saving it, I tried to use the batch upgrader, but no device was detected. I may have to go to plan b for recovering the player...

@cenobyte
Please, please read carefully what other say to You. I bet you didn't read thread knob pointed you to. You are wasting your time as well as ours.
cenobyte:
Ok I have read the full thread now. I examined the memory chip in my player and found it had no Samsung NAND but instead 2 seperate units. On the one with smaller pins, I connected pins 5 and 6 as per the other thread with folded foil. That caused the following device to appear under lsusb:
Bus 001 Device 040: ID 071b:3201 Domain Technologies, Inc.
but no /dev/sdx appears so I cannot really address the drive in a way I know of.
Post Merge: April 11, 2012, 03:52:19 AMI have confirmed that with the same pins shorted on the XP machine, no device appears either under the OS in general, or under the BatchUpgrade program
wodz:
The device enumerates in rockchip specific recover mode (we call it DFU here). In this mode it will not expose any mass storage. If you have proper files you can recover the player. There are various materials how to do it. Other then this you can send arbitrary binary file to the player using rk27load utility (but this is of limited use for now as you basically know nothing about internals of the player).
cenobyte:
OK great so I accessed the famous DFU mode! I expected to find a hard drive, but apparently not.
Post Merge: April 11, 2012, 02:39:38 PMI found this thread which is great, but I need a .rfw file, which I cannot find on the mympxplayer.org.
