I did this as per your post
"To prevent TT Home from downloading & installing Navcore 9.400
Open the ttgo.bif file with Notepad.
Replace lines 9 & 10 with these:
Save this change by clicking "File" in the upper left corner of windows explorer, then "Save as" ttgo.bak. At this point, there is only a ttgo.bak file in the root, no ttgo.bif.
Disconnect & reboot. Now you will have a ttgo.bak, a ttgo.bif & a ttgo.ori file in the root & no TT Home upgrade to Navcore 9.400."
But when I reboot the ttgo.bak is correct but it creates a ttgo.bif as before I changed it and there is no ttg.ori file? Please can you advise as it keeps trying to get me to download Navcore 9.4 which I do not want.
Using the backup "legal" copy with factory settings leads, al least in my case, to the "loop bug" at boot time.
Hi... I tried this way on my Go-730 and it works fine (booting by SD card) :
- Create a secure copy of ttgo.bif named ttgo.ori
- Open ttgo.bif file with Notepad.
- Modify line 9 like this ---> ApplicationVersionVersionNumber=9400
- Modify line 10 seems useless
- Save this change (that overwrites ttgo.bif)
- At this point, there is the new ttgo.bif file and a ttgo.ori in the root
- Connect to TTHome with SD reader ---> only ask for ephemeris or/and mapshare files... no mention of new application 9.4
- There is a message about available maps (probably new 8.85 ones)
- Disconnect as usual and put your SD to boot the Go-730
That's all (under explorer, you will see now a ttgo.bak, a ttgo.bif & a ttgo.ori files in the SD card root)
PS: It seems necessary to repeat the same process before each connection because ttgo.bif goes back to old navcore info even with lines 9 & 10 modified !!!
I hope it will be Ok for you also...

Got it folks, not sure how but I did, might be worth someone who does know to post a "how to" along with it for those like me, anyways, all working on a GO730 with 880 maps.
I just tried it out on my 730, but I prefer the new icons and I also lost some of my commands so I have switched back to 9004.1804 in x40 mode
TomTom Go730 + Bootloader 5.5229 + Navcore SE 9485 + Latest UK Map
Garmin Zumo 660LM + Latest Firmware and Maps
Windows Ultimate 7 64bit + OCZ-SSD + i7 2600K @ 4.6 GHz + 2GB Radeon HD 6970 + 8GB DDR3 1600MHz
Upgraded to v9400 with tthome on a TT530 with v8351 original navcore. Lost loquendo 7 (v6.5 is ok) and amatorial poi's icons are all messed up! (icons are all 22x22 with 4 colors).
The poi's icons messed up are a problem already seen on some navcores....
I'll revert back to a "classical" 9051 SE version....
Sorry...Loquendo 7 is ok
New .bmp icons with 22x22pixel 96dpi and 24bit color (1550 bytes long) are ok. 22x22 72dpi and 4bit color (382 bytes long) are messed up!
