[Q] Help before proceeding.

---

I have never touched a windows phone before but have exp. with Installing unsigned code and ROMS (xbox/360,androids)

With that being said I just received a Windows HTC T8788 from a buddy last night. I have read so many tuts. and info that I have 15 tabs from being sent from one to the other and back again. Here is what I have gathered.

Model:T8788
Carrier:AT&T
Software: Windows 7.5
OS version: 7.10.7720.68
Revsion:003
Radio: 5.69.09.05a_22.50.50.21H
Bootloader version:4.5.2250.0(129685)

Here's the question that sends me in circles and its not the procedure or directions, its which path do I take that is not clear to me to get RSPL/HSPL.
Now for the procedure and Hacks I would like to get but keep finding myself jumping from old to new material.

1) Download WP7F3 and check Bootloader. SPL needs to be 1.5.xx or
lower because DFT program doesn't support the SPL 4.5.xxxx bootloader I
have.
2) So that tells me that a downgrade is needed so that I can RSPL/HSPL then I
can Install Ansars New 8773 ROMs. This is were I get messed up!!!
I found that is has to be a stock provider ROM build;NoDo that has SPL 1.5
Which I found here in this form in FOOTBALLS post:
http://forum.xda-developers.com/show....php?t=1427902
I have also read some were that My version was not able to downgrade
unless i use The goldcard procedure.

I missed a lot of info above but just wanted to clarify were I was
I have no backups of old OS from Zune, Nothing at all. The process to do this is pretty easy just just need someone with windows handset exp. before I take the leap without confirming proper order and software versions.
Sorry If someone take me to the direct link that I couldn't find

So thats it, nobody will even flame me and tell me to to keep reseaching.
Am I missing something. This is Q&A thread for HTC T8788 Sound right?

I wish someone had answer this... Did you have any luck on your own?
