Can we flash over the old ROM?

[sekigah84]

Do we need to do a full wipe or can we just clear dalvik and cache and then flash this?

If you're not already on 1.02 and plan on using the update zip for 1.02 > 1.03, then a full wipe is recommended with amon ra recovery.

I don't reccomend "just flashing over the ROM" with MIK roms the updates are usually rebuilt rather that just updated.
What I reccommend for flashing this or any ROM is
1. Make a nand back up of your present set up.
2. WIPE EVERYTHING I wipe in this order: CACHE-DALVIC-BOOT-SYSTEM-SDCARD:.android_secure
DATA-SDCARD:EXT, Then I wipe ALL userdata/factory reset, I do all of these twice, some do it only once some as much as 3Xs WIPE EVERYTHING EXCEPT SDCARD
3. Flash MIKG (or rom of your choosing)
4.Flash custom kernel
5.reboot(first boot may take upto 10 mins) MIKG reboots twice on first boot(this is not a bootloop)
6.Before you do anything let ROM settle in for about 10 mins., after about 10 mins. unlock lockscreen
7. skip through initial set up, don't set up any accts. yet and check and make sure everything installed(since you did not sign into google, google apps will not be present, this is normal.
8. Reboot into recovery, wipe CACHE and DALVIC-CACHE and reboot phone
9. Now go ahead and sign into all your accounts and set up google and all that good stuff, this time around all google apps(yes this includes the market) should be present
10. Open market install apps if you use TI back up DON'T restore system apps or or data for any app, just restore the app.
I know it seems like the long way to do it but doing it this way has ensured me flawless transitions for ROM to ROM or version to version.
I use Amon-RA recovery and these are steps I do every time I just started doing steps 6,7 and 8 after reading lowetaxes way of flashing new ROMs and it's something I'll be doing from now on.If you have issues read and search I'm sure its been dealt with and solved and you don't have to wait for an answer.Hope this helps!!

When and how do I restore DATA for APPS?

Thanks

If possible, it's better not to restore any data. If you must, you can restore user app data ONLY, and I guess just do it at the end.

Just wondering if the 'don't restore data via Titanium' comment is due to something inherent within MikG's updating from a Froyo ROM the first time, or do you just recommend that as a general rule?

I've always restored USER app data using titanium between MikFroyo versions without a problem. After all if you don't use it to restore apps or data... ummm why have it? (Note, never restore system data.. that's just asking for problems in my experience)

If it's something with MikG/Gingerbread then I've got a LOT of settings to copy down .

You can do it, but as a general rule it's not a great idea. Just nand before you do it and give it a shot. If it messes up you might try to restore one at a time.

I apologize for the newb question. You say:
3. Flash MIKG
4. Flash custom kernel.
Is step 4 optional? Also, How does this work I'm not quite understanding the relationship between ROMs and Kernels. Wouldn't flashing a custom kernel mess up the ROM or something?

thanks,
