FAQ:
Q: After flashing your ROM, the phone is stuck in a loop playing the 4G Splash
A: You need to wipe the data & dalvic-cache before flashing the ROM
Q: Do I need to reflash the radios?
A: NO, once you flash a radio, it sticks regardless of which ROM u flash
Q: Do I need to reflash the kernel?
A: Depends. ROMs will always include a kernel, if u dont like the kernel that's included in the ROM, then u will need to flash the one u want.
Q: Do I need to Wipe?
A: Oh, my Fav question that's asked everyday. It is always recommended to wipe, but it's your choice. If u don't want to wipe, do a nand backup b4 flashing, if you have any issues, restore that nand backup, and you'll be back to where u started....it's that easy.
Q: What is Deodexed?
A: In the base ROM, most of the APKs have an associated odex file. Deodexing converts the odex info back into the APK, eliminating the odex file. This is needed to use themes.
Q: Do I need to wipe when going from a Doedexed ROM to Odex ROM & visa versa?
A: Same as above applies. The deodexed/odex files are in the /system partition which gets formatted anyways, so whether the ROM is odexed or deodexed has not affect on wiping
Restoring Data.img
It's always recommended to wipe b4 flashing. So this is what I do to restore all my settings & apps. Keep in mind, if you wipe after flashing & b4 performing these steps, anything new I have added to /data in the ROM will be gone:
1- Make sure you have
HTC Sync installed on your PC
2- Download & extract
Android SDK, I extracted to C:\SDK
3- copy data.img from your nandroid backup to C:\SDK\tools folder
4- open a command window, type
cd C:\SDK\tools (or whatever your path is)
5- check to make sure it sees your phone, type
adb devices
6- type
adb reboot bootloader
7- when the phone reboots, you'll be in Fastboot
8- verify it says
FASTBOOT USB in red
9- on the pc, type
fastboot flash userdata data.img
10- you'll see a green bar on the top right progressing
11- when done, on the phone, scroll down to reboot....all done!
