[need help]diamond won't pass boot or splash screen after soft reset

[bro4ever]

Guys......I need help

Yesterday I flashed my diamond to mike's 4.7 (I was running calcu's before)

After that i noticed that PIE on mike's is PIE 5, while I need PIE 6.

Therefore, I flashed back to calcu's. this the beginning of my problem.....

after soft reset, my diamond stuck in boot screen (the black screen with "HTC Diamond")

what I have done:

1. resets so many times --> won't fix it
2. hard reset --> wont fix it
3. flashed to calcu's or mike's again wont fix it.
4. the last time I did was flashed back to mike's 4.7, but when I soft reseted it, it seems that i did hard reset (must start tap the screen from the beginning). The fact was I did soft reset only

this problem never happened to me, the starting point was flash using mike 4.7
anyone can help me?
