I have a SDHC card with just a patched copy of NA 3810 on it. I added NC 9.053 & the pre-patched 9.053 ttsystem & PNDNavigator files. It booted on my X20 unit, with no problem. You might try it this way.

Not sure if it is really realted, but I tried a few NC's and Bootloaders on my 730 with a weird result (doe to me being too curious about jt98's) problem...
5.5112 : works great for USB but makes my V9 NC freeze after about 2min
5.5120 : good for USB but 3 V9 NC's I tried won't even start, they do freeze up at the start
5.5128 : USB transfer hangs quite often and is slow but V9 NC worked fine
5.5259 : USB good 3 tested V9 NC's run with no problems

So it seems that even 5.5120 is high enough for the V8 NC's and supports SDHC it might not work with every V9 Navcore.
The lowest BL for a V9 NC that I could find in my collection is the 5.5136, so mabe V9 NC's do need a BL higher than 5.5128 at least for some devices?

I tried NC 9.053 & the pre-patched 9.053 ttsystem & PNDNavigator files. Added map 8310. But still TT is stuck at splash screen.

Remove the SD card from your unit.

Download & unzip this attached file. Copy it to the 930 internal. Disconnect & reboot. Shut down, install the card & reboot.

I am little nevous overwriting the internal system file. If this doesn't work will I be able to get
back to original 8251 navcore?

Navitotal has never "bricked" a unit. We wouldn't ask you to do anything that wasn't safe. I mentioned in an earlier post that I have a GO X20. You can't imagine what I have put it thru, so I can safely help our members.

Thanks. I did put the downloaded bootloader and system ile on TT internal memory.
Inserted the SD card but still stuck at splash screen.

Took the card out and the TT startup is ok.
Now when I tap on the TT screen version number, the details shows
BootLoaderVersion=55274
App=8.351(9982/090518) OS:315187

Thanks

Cut everything on the internal & paste it in a new folder on your desktop.

Transfer everything on the card to the internal. Disconnect & reboot. This should tell if it is a hardware or software problem

I think all he needs to do is try again the SD.
He had the SD in, so the Bootloader was not installed.
After removing the SD it booted from internal memory and installed the BL.
But I think has not checked if the SD works now - if not something must be wrong on the SD.

You might be right, if he didn't follow the instructions in post 21. They cover exactly what you are referring to here.

Sorry if I am not following the instructions. I really appreciate your help.

Not a problem. If you still have the "new stuff" on the card, disregard post 25 for now. Remove the card. reboot. Shut down. Insert the card & reboot.

I did reformat the card and installed the 9053 again. When the card is connected to the
computer via card reader, it is connected to the TT Home application. I can see the patched 880.3810 map and browse through the TT menus.
When I insert the card in TT and reboot TT, it seems to boot from the internal memory(as the internal memory (as it complains no map found because the map and patched navcore are in sd card) rather than the SD card.
