Transform a Nuvi 37xx in a Nuvi 34xx for dummies

Firmware.rgn is normal 34xx gupdate.gcd saved as .rgn with RGN Tool by turboccc, no need any modding.
Get simply 34xx firmware from Garmin update page, extract .rgn and flash following with care the procedure and instructions in post n1.

silly question here i know i read this here but want to double check with you guys.

1. Can i use webupdater to update fw from my converted 37xx/34xx? just need to be patient because it takes a while to load (more than 5mins) then after fw updates clear non vol and point mass storage?
2. If not just use the normal flashing method?

Here is the size of other Garmin devices FW files to compare with 34xx/35xx :
- 34xx/35xx :77,63 Mb
- 37xx : 50.75 Mb
- 24xx : 38.16 Mb
- 1490TV : 15.8 Mb
- Montana : 16.5 Mb
- 62st : 5.34 Mb
- 7xx : 9.5 Mb
- 2x5w : 8.91 Mb

You can see that the difference in size and time to load is ...huge!!!

Please help: I had enable all feature in Nuvi 3450 from post#1 (Enable Features files.rar), now Garmin want me to return the unit back because of a dot dot line inside the screen after webUpater to 7.10. How do i remove all those feature back, like voice command, video, etc.

Thanks

The same way you enabled features. The only difference is the file names. They must be with text "disabled" instead of "enabled".
DeviceConfig_VideoPlayback_Enabled.xml -> DeviceConfig_VideoPlayback_Disabled.xml etc.

I did do that. I put just one DeviceConfig_VideoPlayback_Disabled.xml and restart my gps . It still show video icon.
The xml is place inside X:/Garmin/xxxxxx.xml

Have you copied UpdateDeviceConfig.xml too ?This file at the end of the list ,must be added to other.xml files if you want to change configuration

Yes I did. I copy updatedDeviceConfig, disabled.xml to Garmin folder. Then hold power until it pop up asking to turn off, then i click off. a few second later i turn it back on, still not working.
