Hi!
X3 rockboxed here: the player starts and works normally with rockbox.
But since several weeks I have problems with dual boot.
When I try to boot the stock firmware the screen remains black.
If I press the reset button with the lock button on, nothing happens.
After this attempts, also rockbox doesn't boot: I must press the reset button (with lock button off), then the RB comes back.
What can I do to solve this problem?
I'm here again because I got the same problem mentioned some days ago.
The LOCK switch seems to work...Try to power on the X3 with the LOCK ON (and OFF afterwards if nothing happens) keeping the reset button pressed for cca. 30 seconds.
Btw... have you tried removing any uSD cards and activate the LOCK switch?
I tried several times but without success.
This is what I do: with LOCK ON, if I try to power on the player, I heard a little "click", but the screen remains black.
(I heard this little click everytime I power on the X3 in rockbox mode and I know this is normal)
After this, I can do nothing more: I can not power on in rockbox mode (with the LOCK OFF) and I can not reset the player with LOCK ON.
The only thing that works is press the reset button with LOCK OFF, then the player boot normally in rockobx mode.
After many attempts, I don't know why, this afternoon the player boot in stock mode.
Then I tried to uninstall Rockbox and install Stock firmware, using the update-back-to-stock.zip and running the firmware update, as mentioned in the manual.
After a very short time, the player gave me the message "Upgrade succeed" (or something similar) then rebooted... in rockbox mode!
I thing that there is something wrong in my player but I don't know what to do...
I have the same problem. Probably some corrupted CMOS of something.
The solution:
Manually reflash RB with win xp or win 7
I don't have any pc with Win7 or WinXP at home, only Win10: can I do the manually reflash with a virtual machine with Win7?
