Help/Warning: Error with HiFiMan HM-801 rockbox uninstall
ivanrocks321:
I have tried to remove the HM-801 port following these instructions from Head-Fi http://www.head-fi.org/t/579759/how-to-installing-and-uninstalling-rockbox-to-the-hifiman-hm-801-603-602-and-601
I followed the instruction but the progress stopped at the part where you load the original firmware using the .exe. So I tried the process again but I keep getting some error messages but I can tell what going on exactly because the menu is full of the jumbled kind of symbols. I have attached a screen shot of the message I was getting. I have also tried several different versions of HM-801 firmware including the latest 0.21, 0.2, and 0.19.
If anyone has an idea what I may try to fix this problem I would deeply grateful, since while rockbox is very good so far on HM-801 but it still has one key feature lacking thats the USB dac/amp feature that I am dearly missing now :'(
And for all that are thinking about installing rockbox on the HM-801, I guess this is my heads up to you.

I had the same problem myself recently, had to resort to shorting out the flash memory pins several times.
The good news is it is nearly impossible to brick rk27xx based devices, but you do need to be persistent with the recovery attempts. The device will always fall back to DFU mode at some point.
Try using "RK27BatchUpgrade_Image.exe" and tick the erase box. I found I had to keep trying several times in succession and hitting the upgrade button while keeping the device connected up to usb.
Hope this helps.

Thanks for that bit of info, where can I get this .exe I think the one I have been using is looks different from yours. Would I also have to short my 801 before running this exe?
mortalis:
Try to short out pins on flash chip instead of Step 3 in instructions from head-fi.
You need to find samsung flash chip and short out 5 and 6 pins from the bottom on the right side, look at this photo (this is photo of HM-601, but HM-801 had the same flash chip).
With connected 5&6 pins, connect player to PC via usb. After one or two seconds remove connection between pins.
Then follow steps 4-6 from instructions
