My D1 finally died and I got my hands on a cheap D2. I was winding up to flash a new ROM on my D2 but I started seeing terms like "2nd Init ROM" and now I'm suddenly not sure what to do. I think I was horribly spoiled by the unlocked bootloader on my D1 and I was able to flash any ROM without fear. (I was generally running SS, MIUI or Liquid) The D2 does not seem so forgiving. No overclocking is a bit painful as well, but my D1 wouldnt go over 1Ghz anyway, so that's a wash... So :
What is a 2nd Init ROM, and how do I tell the difference?
Do I need to flash back to stock, re-root and re-run Bootstrap every time I change ROMs?
How easy is it to brick this thing?
Is it possible to unlock the boot loader?
Is it possible to overclock?
Can I really install any DX ROM and have it work OK?
What is the performance penalty for running Boot Manager and having the ROM run off of SD?
I have looked around for these answers and have not found any clear explanations. Any help on these items would be appreciated.
