Before we start do a backup of your data! Better be save than sorry!
To update the GSM version of the HTC Hero (also known as T-Mobile G2) you first have to get the following:
1) flashrec - flashes the recovery partition to Android devices (works with Android 1.5, sources and development here), newest version by the time of writing: flashrec-1.1.3-20091107-2.apk
2) RA-hero Recovery ROM - important for nandroid backup, wipe and flash, actual version: RA-Hero-v1.6.2
3) New Radio-Firmware - for a better connection - newest version: 63.18.55.06OU_6.35.15.01
4) A custom ROM - like VillainROM, SenseHero (development here) or MoDaCoROM - there are more out there! ;)
Now we are copying this files to the root of the SD-Card on your HTC Hero. With a Filemanager capable of running .apk's (for example Linda File Manager) we install flashrec from our SD-Card. After that we run flashrec, make the recovery and then insert /sd-card/recovery-RA-hero-v1.6.2.img - now press the button below.
Turn of the mobile. When you restart the mobile first hold the Home-Button (and turn on the phone) and keep Home pressed until you are on the Recovery Screen. Here you should first make a nandroid backup, then flash the Radio. After that reboot it and start Android - see, if everything is still working ;)
When you restart into the recovery mode you should now make a wipe (also from dalvik cache) - this will delete all your personal data (except from SD-Card). Now flash the Custom ROM of your choice and reboot. This may take a while, so be patient! Now enjoy your new firmware! :)

Efika SmartFirmware 1.3 20070122 Update
Just found a OpenFirmware update for the Efika5k2 board with version number 1.3 and build on 2007-01-22 here. Normaly your board should have this build date (20070122), but there is also a 1.3 version with this build date: 20061107.
To check which version you have you have to enter the following on the openfirmware:
1) cd /
2) cd /openprom
3) .properties
4) look at the build-on value
To install the new version you have to get the file and enter the following like described on the site:
1) Put the extracted file onto a USB-Stick and insert it into the Efika PPC
2) Type on the openfirmware promt "boot scsi:0 update_e_20070122"

Efika PPC board battery problems
My Efika board had a quite long time no power supply, so the onboard battery (CR2032, 3V) was empty when i tried to install the brand new MorphOS 2.5. So i got a wrong MAC address, the date was in the year 2105, and so on... Also registering MorphOS (application under MorphOS-Partition:Tools) will not work correctly (the personal Key-File is bound to the MAC address).
The solution was simple:
1) Power down the Efika5k2
2) Remove empty Battery and wait for a few seconds
3) Power up Efika and stop on the openfirmware SmartFirmware
4) cd /
5) cd /builtin/ethernet
6) .properties
7) There you see the original MAC address - write it down, just in case
8) boot
9) After MorphOS booted open a new shell and check the MAC with ifconfig
10) If the MAC is ok insert a new CR2032 Battery into the running system, if not, repeat from step 1).
