I'm trying to use wake-from-halt on my Raspberry Pi A+, but it does not work. According to elinux.org/RPI_safe_mode#cite_note-1 When using bootcode.bin dated 12/04/2012 or later, the same two pins (5 & 6) can be momentarily shorted to wake the Raspberry Pi from the halted state. But this does not work :(

I also tried updating the bootloader. Is this feature implemented for the A+?

uname -a: Linux raspberrypi 4.14.34+ #1110 Mon Apr 16 14:51:42 BST 2018 armv6l GNU/Linux

The script to halt the raspberry pi is working without any problems

I an not sure you can actually "halt" the Pi with current Raspbian (although you may be able to write assembler to do so); all the normal shutdown commands run the same code.

The pin 5/6 does work (subject to a few caveats) - although I haven't tried on an A+ it works on all the B models.

If you want safe shutdown, Raspbian now includes code to do this dtoverlay=gpio-shutdown you don't need ANY code. See Raspberry Pi 3 model B "dtoverlay=gpio-shutdown"
