I am trying to flash Gingerbread and Mikfroyo. I already have Clockworkmod installed on my phone. I don't know how to save the rom to my sdcard and then flash from there.
- This post is assuming the EVO 4G is similar to the Epic 4G with connecting to your computer (I have an Epic 4G) -
This is how I do it on my Epic 4G, there might be differences between the 2 phones.
Make sure you have the drivers for your device installed on your computer. Once thats done, go to "settings > applications > development > enable usb debugging". Once thats done, plug your phone into the USB port on your computer. Once thats done, go to your phone and drag down the notification bar, you should see "USB connected, select to copy files to/from your computer" press that. Then press "connect USB storage". You should get a pop up on your computer, click "open folder to view files". After you do that you should get a window that opens up that is your "Removable disk (E: )", that is where you want to put files on your sd card. I usually click and drag the zip files from my desktop (thats where I put them after downloading) to my "Removable disk (E: )". Then I close that, go back to my phone and turn off usb storage, then unplug my phone from the computer.
Then I power off the phone, boot into clockwork, and follow the install instructions as advised for the ROM.
I would double check this in the EVO 4G forum though, to make sure the devices connect to the computer similarly.
