Hi Guys
I'm using firmware 3004.388.4 beta2. What custom configuration script should I use for this beta firmware update from 388.2.2. I tried installing the beta 3 version of this firmware but it won't install it stays at beta 2 any ideas. Another query is I tried to re-install the 388.2.2 f/w but it won't install is this normal.

On which router model do you have this issue?

Typically the update fails due memory shortage - unplug the USB-Stick(s) and reboot - try the update immediately after reboot (without USB-Sticks).

To clear memory cache without reboot you can use this commands on the command line (SSH login):
free  # Show memory usage BEFORE clear commands

sync; swapoff -a  # Clear Swap-File(s)
sync; echo 3 > /proc/sys/vm/drop_caches  # Clear PageCache, dentries and inodes.
sync; echo 1 > /proc/sys/vm/drop_caches  # Back to normal memory usage

free  # Show memory usage AFTER clear commands
