Help needed for Rom Update

[tekton]

I am trying to update the rom of my trinity (from image version 1.20.408.1 to image version 1.15.405.5).

I get following error message: [Error] Invalid vender ID

I presume that "vender" is just "vendor" misstyped by somebody.

Anyway, the error message tells me, I believe, that there is a conflict of vendors (brands).

How can I overcome this ? Is there any utility that can help me to delete/remove or otherwise outplace the "vender-ID" ?

I am absolutely unexperienced, so please do not blame me for asking something that is probably very simple for experienced people.

I would like to add that I know that tweaking too much with a device can ruin it and make it a brick. But I have very good reason to need to erase the actual Rom and install a new one. And learning to erase and install any rom on this device

Thank you for help and suggestions.

First, it looks like you are downgrading?
Second, if you check other device´s forums, (see Prophet) you'll find a lot of info about error codes, Country ID locking, etc.

This is common info for most HTC devices, read the forum for a while and you'll find the answers.

In my opinion it's a bit too soon for upgrades. Although they will come, indeed....¡¡
