I bought my phone a month ago but I do not have any plans to do any flashing thing about it except from having a developer-unlock WP7.5 OS. Yes, Windows Phone 7.5 Mango installed in my newly bought HTC 7 Mozart. Unfortunately, I was 3 days late when CheveronWP7 closed. 4 days of frustration and researching ways to have a developer-unlock phone and I finally decided have my SPL downgraded to 1.x from having an SPL 5.11 so I could just have a developer-unlock OS.
Some video was a little bit shaky because I was currently in a vacation and I don't have all my stuff for making a nice video plus I was just squatting around so it's really shaky (sometimes). Sorry.
A LITTLE PREPARATION THOUGH

A VIDEO GUIDE FROM DOWNGRADING YOUR SPL TO 1.xx
My phone was originally SPL 5.11 so I downgraded it to SPL1.26. Want to flash your custom ROM now?? THEN DOWNGRADE!!! NO MORE WAITING FOR ME!
Making a Y-CABLE is easy as tying your shoes
USB Extension Cable (white) - Php70 (insulated) - $1.59 (USD)
MicroUSB Cable (black) - Php120 (not insulated. disappointed with it) - $2.72 (USD)
1GB MicroSD (CD-R King) - Php180 - $4(USD)
Card Reader (Multiple card port / CD-R King) - Php50 - $1.13 (USD)
Total: Php 420 - $9.5 (USD)
And of course, you have to HSPL your device http://forum.xda-developers.com/show....php?t=1195647 AS ALWAYS. I saw some guys asking if this is necessary .. well of course it is!
AND THE 28minutes 59seconds VIDEO
The number 28:59 means I done everything for less than 30minutes+ or so from downgrading my SPL to executing RSPL and HSPL.
You might hear some weird Beavis sound, sorry, that was me.. I'm just diverting because I was bit scared something bad might happen to my Mozart .. but it turns out that everything went well.
