Background: I have older TT One XL with 8.010 Navcore. Tried to update to 9.026. D/L Basicpack and SE. Extracted both to 4GB SD card plus your Samantha Vocalizer TTS and maps NA 845.2645 to created folder North_America_845_2645. All went well except that my Bootloader 5.3026 cannot read SD cards. Backed up everything from TT device and after deleting from TT device, I tried to copy SD card to the device itself but there wasn't enough space so I put the backup back to the device. Works fine except that I'm back to where I started.
Questions: Is there a way to put TTS on 8.010? I can't find any entries "ttsoff" to delete. I know it's not recommended but is there any way to update my bootloader to a version that can read SD cards?
