ITS ALIIIIVVVVVVEEEE!!!! Hahahaha!!!
I ran the Phoenix Pro Tool software. Selected the Sochip "certificate" file included and selected my firmware (Sumvision Cyclone Pocket v303 at the time).
I disassembled the unit and located the Samsung DRAM chip. Took a flat screwdriver and shorted the pins according to attached picture (around the 5th-8th pins from the edge of the chip that's closest to the power button). I've marker the area in the image attached in red.
Then I pressed and held the play button on the remote and pressed the power button on the unit.
With the play button still held down I plugged the USB cable into the PC and released the play button. Windows detected it. I then removed the screwdriver that was shorting the pins.
The remainder of the steps are the same as the guides from Warrior Poet.
I know the shorting of the chip is risky but it was a last ditch effort... and it worked!!!!
I did very much the same thing as you with the Cyclone Pocket firmware and had the remote work but the buttons were all switched around as well. I did not find a Micca firmware for the proper device. I did however speak with Ider and they sent me a firmware yesterday. I did not try it yet as I was worried if it didn't work I would brick the unit. At least right now with the cyclone I can make it work (just have to remember the right buttons).
If you are interested I will send what they sent me. The file is labeled "ePDKv100.img" and the size is 23.0MB. Of course I would love someone else to try this before me
I suspect the Micca firmware was corrupt or only works for a certain version of the player that's why it bricked mine. I noticed that they pulled the firmware from the product page now so that could justify it.
Thanks for the offer but I've also received an updated firmware from Ider on the 22/10/2011, its named something like. "F8(F10)_23_09_2011.IMG". I updated it and it works flawlessly. I'll provide the link when I get home today if you'd like it. This firmware is for the F8 which Futeko says is a newer model than the I6FH but it just shows that's its exactly the same unit just updated firmware. It also plays MKV compressed headers which some rebranded units with certain firmware versions don't.
FYI I used the sochip modding tools to extract the firmware image and I found the exact same layout with the sumvision cyclone pocket and micca slim-hd firmware. Only differences I've seen is that sumvision is a lot more cleaned up. Micca has two versions of driver files for certain components and the theme files for the images are not packaged in bin format so you can view them as they are bitmap images. I wanted to swap the uart.drv driver as I think that's the remote driver but I there isn't clear instructions on how to package the firmware up again.
