Thanks for reply
Sorry to hear you are having problems with your 770c. I have not experienced any of these problems; you might want to try to re-firmware your player to see if this helps. I have a copy of the 770c firmware that I can try to send to you, if you want. If this does not work, then you may have a defective player. So, just to make sure if I understand, you are having problems playing files on your microsd, or you are having problems adding files to the microsd card while it is in the player? I have used several different microsd cards in my 770c and I have had no problems at all with the player reading form the card. Now, if you are talking about a problem trying to add files to a microsd card >64 gb while it is in the player, then this is a problem with all the Xuelin players. Don't ask me why, but I have emailed Xuelin about this. I have never had a problem with my language settings. When you talk about shuffle setting, are you saying that if you choose the setting "all music" on your player and all files in your internal memory are listed that the 770c will not play in "shuffle" mode? This has not been a problem for me. I have also asked Xuelin to consider a firmware update that will have the 770s list all files in the internal memory as well as the microsd card when "all music" is selected.
I have 8 x 32GB micro SD cards all formatted FAT32 and all containing music that plays on all my different players - with 4 of these cards in the 770c player- it does not recognize the card and comes with file error. This is strange as even my shozy alien will recognize all of them
I will try to re- firmware the player as you suggest to see if this helps
The shuffle for me only works on the folder that you are playing music from and will not shuffle between folders or between the internal memory and the SD card. When using shuffle on the internal memory again it only works within the folder of music I am playing from
