Ok I'm looking to install new/bigger memory card (1gb to 8gb sdhc) for more memory after maintenance. I'm currently running Aloysious 2.0.9 Maps, looking to run new Custom ROM after my Sprint Store Visit. My vibrate mode stop working recently, so I'm gonna take back to Sprint cuz its still under warranty. I know I have to Unroot first before i take back, so i will. Do i Unroot to the 2.27 OR the 2.31 stock ROM? Will i be able to ROOT back to a new Custom ROM like LiquidSense 2.1, CM6, or aospMod v0.9.7 How/What files do i need to transfer over from my old card to new card after or before i flash new Custom ROM Thanks for the help!
