I should know better. But are samMobile .zip (stock roms) CWM flashable, or are they to be extracted for ODIN ? When you've finished mocking/laughing and generally extracting the urine from me. Please let me know. Wife has a problem with her Galaxy Ace (GT-S5830i) the newer version, it won't pick up a signal nor let her SIM register, SIM is fine in three other phones. So I thought I'd root it (dead easy - don't even need ODIN) use CWM from stock recovery after rooting (you flash CWM and it opens to CWM recovery) and then flash the stock ROM for her. Then unroot. Downloaded the stock firmware twice now and it keeps telling me its 'bad' from CWM recovery. Hmmm. Wrong forum really ! LOL just wanted an answer.
