hi all,

i plan to get SGS soon and being a WM6 user, i'm rather 'noob' to android custom rom. i had basically ran through some FAQs available on XDA forum but there're doubts that i would appreciate some clarifications from fella forumers:

assuming if i'm on stock rom Eclair 2.1,to flash to a custom rom, say doc's v8:

1. do i have to 'root' my device? if yes, which approach to apply?
i saw two options recommended:
a. chainfire's tool -- i'm confused of which one to use?

b. SuperOneClick v1.5.5 -- this seems to be seemless, any risk?

2. once i'm 'rooted', is it considered permanent (similar to Hard SPL in WinMo cooked rom?) if it is not permanent, do i have to repeat step 1. above each time i need to flash a new custom rom?

3. under "Pre-Requisites" on doc's page, it says:
a. "Disable Voodoo if have it installed" -- what is voodoo? do i have it with stock rom?
b. "Make sure have the 2e recovery. If you don't have 2e recovery, see FAQ." -- what is 2e? how to get them?

4. on custom rom installation, it says:
"Download clockworkmod recovery from here. You *need* Clockworkmod, this won’t work with stock recovery." -- is this 'rooting'? if i've done with step 1. above, do i still need this?

5. i have saw somewhere you can also flash rom with odin3, in the case with doc's rom, is odin3 still applicable?

6. in odin, when was the time that i should use:

a. PIT
b. PDA
c. PHONE
d. CSC?

really appreciate some experienced forumers can shed some lights as i'm a little worry of wrong-doing as i plan to flash to custom rom the moment i got it. thanks a million.

@silentser and @plaz

thank you so much for the detailed explanations. guess i will call it a day for now until i have the phone on hand. i'm sure there are more questions to ask by then. hope you guys don't mind if more questions are on the way.. haha

haha.. sounds familiar during my days with WinMo cooked rom, at peak, i reflashed cooked rom 3 times a week. and now my dopod d810 is 'almost' dead. i think this new baby gonna kill my sleep too.

two silly questions:

1. does SGS with android 2.1 and above supports video call over 3g/wifi?
2. with the stock android 2.1/2.2 installed, do we still need to apply lagfix?
