How like, risky is this? I assume not much bad can happen , as it is just overwriting the splash .... How would I go about returning to the original?
if you have to flash an ruu,it contains splash1.nb0,so it will automatically change back if you ever flash a signed ruu to go back to stock. if you just happen to want it back with your custom rom,easiest way is to flash it just like you will flash the replacement.
easy place to get it is just extract a PD98IMG version of a full,signed ruu,then delete everything but splash1.nb0 and android info text document. then place on sd card,named PD98IMG and flash in hboot as described above.
as for the risk,ive never heard of a bad splash flash making a phone unuseable,tho i guess anything is technically possible. there is a certain amount of risk in
anything you do to your phone(other than leave it completely alone

)
i could walk you thru using fastboot flash
Sorry for being so stupid.. but is that what you've already explained?? I'm gonna try to do this soon... When's a good time , so that I can quickly contatct you when stuff goes wrong?
no need to apologize... hboot and fastboot are easily confused by beginning rooters of htc phones

what i described was how to flash in
hboot.
fastboot flash is a fastboot command. the short version of using it to flash a splash image would be:
-put image into folder that contains adb/fastboot utilitys
-open cmd window and chage to that directory
-put phone in fastboot mode and connect
-type
fastboot devices
if you get a serial number,then youre connected.
-
fastboot flash splash1 splashimagename.img (assuming youre using an image. flashing the stock one back would be
splashimagename.nb0)
then there is a third method that involves flashing a PD98IMG file(that you would flash in
hboot) by putting that file into the adb/fastboot folder and using a few fastboot commands. i wont go into that yet,as i have prolly allready made things somewhat confusing
