Hi, im updating my Samsung YP-R0 to the latest version of developer builds (a5df94beb5) and after that it cannot boot to RB (it keep back to system checking).
I wonder what was wrong? im using dual boot os bootloader from Vannix at ABI forums.
Is anyone can help?
Thx in advance.

I just installed the latest developer build on my YP-R0 ef05dc9c3b and it seems to be working fine for me, i don't have the bootloader set to dual, I have set to boot Rockbox by default. using bootl.cfg on root of SD card, below is my config:-

Sorry, I missed this thread.
"System checking" in a loop probably means your YP-R0 is bricked.
It probably occurred after your connected your R0 to the PC to update the Rockbox build then disconnected it. It automatically updated the Samsung library and it failed.
This is an infamous bug in any firmware version. It was much discussed on the forums back to the time but some of them like ABI are now down unfortunately.
If you had the original firmware installed (let's say 1.25), you would be in troubles because only the Samsung recovery tool and a special 301 KOhm USB cable could fix it.
But since you seem to have the Modfirm v2.51 dualboot (from Lorenzo92 by the way. VanniX did the Rockbox-only LightROM 4.6), it can be easily fixed with the Safe Mode.
Let me know here if you still need help.

Thanks Lebellium, back in the days my YP-R0 working again by put the new RB copy on internal memory. Seems that RB V 3.15 more stable now on this device, i dont hearing any buggy sound or the music stop playing by itself.
Thanks
