I'm trying to install CM10.0 to my Samsung Captivate. It has been rooted for years, but I have never flashed a ROM before. I decided that the easiest way would be to use ROM Manager. I downloaded it from Google Play and clicked on Flash ClockworkMod Recovery. After choosing Captivate from the next screen and confirming that I want to flash CWM it works for about 20 second then says "Successfully flashed ClockworkMod recovery!" I have previously downloaded the latest stable release of CM10.0 onto my SD card, so I choose "Install ROM from SD card." After choosing the zip file it reboots into recovery mode, and comes up with "Android system recovery <3e>" and tells me "E:failed to verify whole-file signature" "E:Signature Verification failed" "Installation aborted" It looks like CWM didn't get flashed right? So, I read up on how to flash manually and went out and grabbed Heimdall as well as ClockworkMod. When through the steps to get the drivers installed on my Windows 7 machine with out any problems, got the phone in download mode, but then when I use the command line to use Heimdall to install the ClockworkMod it tells me it is missing MSVcr100.dll. Okay, just install Microsoft Visual C++ Redistributable right? No. My system tells me a newer version is already installed, and nothing I do can get it to install the version that Heimdall's website says is needed. Now I can't seem to get ClockworkMod on my phone at all. Halp? Cliffs: ROM Manager says it installed ClockworkMod, but didn't. Heimdall wants MSVcr100.dll Windows says that a newer version is already installed. Can't Flash a new ROM because I can't get CWM.
