Root [CDMA] Complete Newbie's Guide to rooting and flashing Evo 3D ROMs/Kernels using fastboot

Are you hiding your extensions in Windows? Check in Folder Options in Control Panel. In the View tab, I think. Sometimes people don't see them by default. So they accidentally name the file recovery.img.img. If so, remove one of the .img's. If that doesn't work, use the RUU flashing guide to flash the RUU and try re-rooting, again.

Thank you for responding. I am not hiding file extensions, and the file is named recovery.img. I followed the steps outlined in your RUU flash guide here (http://androidforums.com/evo-3d-all...mware-upgrade-ruu-flash-unbricking-guide.html), but I am still getting the same error message (BootMagic check fail). The phone is not bricked or anything, I can still boot into stock Android. Not sure how to get around this problem. Thanks!

I followed your guide except that I did not install the custom ROM. So do I have to install the custom ROM in order to be rooted? I just want to root and stay in stock. I tried installing superuser from the market but it says that I don;t have root access.

The ROM included in this walkthrough is the stock Sprint ROM with Superuser built in. Flashing the stock ROM + SU built in usually causes fewer problems then just flashing the SU patch over the stock ROM.

Both result in a rooted stock ROM, but the full stock ROM will install with fewer problems. However, if you just want to flash the SU patch, it here:

What if i use 4ext recovery ??
And what exactly are firmware files....do i need them for flashing new roms ??

Sorry, I missed your question.

4EXT removes the need for fastboot to flash ROMs/kernels, but if you want to update firmware, you'll still have to use a RUU or unroot and take an OTA.

Thank you for the great guide and the reply. I had actually gone ahead and installed the ROM you suggested in your guide. You can probably mention that the ROM is stock and rooted, but other than that, your guide is very easy to follow and straight forward. I am going to flash an ICS ROM right now. I hope that it's okay to use the recovery in your guide to flash the MeanROM (I'm S-OFF using the pin trick). Thanks again.

You'll be fine to use either TWRP 1.1.1 or 4EXT

Still having this problem... any ideas on how I can get the custom rom on there?

Try downloading a fresh copy of TWRP 1.1.1. You may have a corrupted download. If not, I'm not completely sure, I've never seen that error before.

Do u mean for official updates??:thinking:

No, like updated basebands/radios and things of that nature. It will only be a big deal once the official ICS comes, as I'm sure there will be updated firmware for it.
