First i see a screen with "Installing Patch"
Then mede8er reboot and it installed the Beta4 Firmware.
Then the progress bar stops at 3/4 and the mede8er hangs up.
Internal Disk is a 2 TB Hitachi HDS72202 and formatted by mede8er setup.
I have a Samsung LE40B750 over HDMI and a Yamaha RX-V 661 over Coaxial connected.LAN is wired (D-Link DIR-655)
I suggest the following to try:
- please remove all usb devices, only connect the usb stick with the fw on it (17L patch version), with the 2 files on the root of the stick
- maybe also disconnect the internal disk temporary, just to be sure that is not causing the hang during upgrade.
Reading your comments the L17 bootloader update fails. And because its fails, V4 cannot be loaded because it needs the 26 bootloader to run.
We need to find out why the 26 update is not working for you.
