      I gave up on ICS and went with the Jelly Bean. I used a SlimBean rom and it works great except for video capture (doesn't work) and some videos do not play like Netflix. I don't mind as I do not use this device as a phone or video player. I mainly stream music from TuneIn, Pandora, etc. Works great for that.

      You can see my screen shot here:

      I have an HTC Evo 4G that I have unlocked and rooted. I have a proper backup program for it. When I try to flash the

      file from the SD card I get the error in the photo.

      If you are not already rooted and have the most up to date HTC software version you will not be able to root without rolling back your bootloader version. Try for current instructions. Go to HTC EVO 4G-all things root. Links to many ROM's there as well.

      The OP assumes that you've installed a recovery app like ClockworkMod or AmonRa. When you enter recovery with those apps, you'll have the option to install from a zip.

      My EVO 4G CANNOT be updated to ICS using the method outlined above. After I wipe everything and go to the main menu to install ics, "INSTALL ZIP FROM SD CARD" IS NOT A MENU OPTION. I've read this same set of instructions on four different sites. You people need to quit plagiarizing from each other and do some actual work to accomplish what you're telling people they can do with stuff like this. You're out in left field on this one and probably most others. DAMN RIGHT YOU CAN EMAIL ME -

      This article doesn't mention that ICS on the EVO is STILL an alpha/beta development platform! Not only are the download links broken in the article (the 'old' version is now 3 days old), these things change daily (see previous comment lol, camera and maybe gallery is "fixed" now (maybe)), the ROMS will not be optimized yet so battery strength will/may be worse than you are used to, and there ARE more problems than just those listed. Not wanting to run anyone away, but these are still just for testing.

      For those of you who just want to install ICS on your Evo and go on with your life, don't expect to use these for the next year as you will most likely be very disappointed when you find things work poorly or don't work at all... I would recommend waiting for a few more months until more bugs are worked out. If you are a ROM tester, you already have known about ICS on Evo for months now, so carry on.
