Lightbulb [Q] Challengings for Brain users like me!

Hi guys,

First of all, i apologize if I post in a wrong forum, kind of new in XDA. Wanted to thank you all, because, even though, I didn't register, your forum helps me A LOT with android phones... I'm facing a situation with an HTC, and as I surfed the web, and no one seems to have the same problem, I'm adressing it in this forum.

I bought an refurbished mytouch 4g glacier on amazon. When it came, in addition to be locked (not a big problem), I couldn't enter the settings (the linked program is no longer installed on your phone) and worst, there is no dialpad. I assumed that the owner tried to flash it with a corrupt version...
As it is for me a brain challenge, i decided to try to fix it...

I made a factory reset with the buttons (pwr+vol down), same thing! I tried recovery, I think with the S-ON, it didn't work (red triangle). I tried to use wifi to download things or a file manager, but you'll need to access the settings options, and I don't have access. I download SDK manager, but the phone needs to be usb debugging to be found by pc, and I can't access the settings options. I download an usb debugging apk, put it in the sd card, but as there is no file explorer, I could access it...

This is why I asked your help. This is a Glacier pvt ship s-on, with green fonts, (cyanogen 7?: there were a difference with green fonts and orange fonts...)

Thanks in advance.
