I havent seen g since i've had my evo. Im sure Tampa is a 4g city. Is there any way to see if it was taken out during rooting?
Yes. Install wimax key checker from the market. You'll also need busybox installed if it isn't already. You can also install the terminal emulator from the market. Open it and type "su" without quotes. The prompt will change from $ to #. Once it does, type:
grep RSA /dev/mtd/mtd0
You will get several lines of output. If your 4g keys are in tact, the last two lines will look like this:
-----BEGIN RSA PRIVATE KEY-----
-----END RSA PRIVATE KEY-----
If the above fails, you've lost 4g for good unless you have a nandroid backup from before you lost your keys. If you lost them while rooting (kind of unlikely), you're pretty much done.
If the above all looks good, can you explain what happens when you try turning on 4g?

Lol, yes you need to turn it on if you want to use it. Menu->settings-wireless & networks, then select the checkbox that says 4g to turn it on. You can also use a 4g toggle widget.
hmmm....I don't see the checkbox for 4g. I have the CyanogenMod
Lol, I suppose I should have asked some of these basic questions before having you look at the complicated stuff . Xtreme is correct - AOSP ROMs don't support 4g, with the exception of the alpha, which eventually lead to full 4g support for CM - eventually. Here it is for CM7:
[ROM][gginggerbread-6] - Wimax for cm7! Self-replicating code is self-replicating - xda-developers
So with this I can have 4g? What exactly is it?
That is another ROM, that is based off of CM7. It does have 4G working, although I haven't tested it myself.
So...I should follow these steps?
1) Perform a nandroid backup of my current state.
2) Backup all contacts and apps
3) Download the rom to my sdcard
3) Go to Rom Manager
-select flash Rom
Then my Evo will boot into this new CM7 based Rom? How different is it? Anyone have experience with it?
out of curiosity have you checked out the rooting for dummies guide section 3 after rooting?
cyanogen mod 7 (cm7) is a rom that is an aosp (android operating source project) based rom. it is also a non-htc sense rom. any aosp rom at the moment will not have 4g and hdmi working except for the cm7 beta that is out there. i heard that cm7 still has some bugs that needs to be worked out yet.
so basically you need to
1)make a nandroid backup
2)wipe data factory reset, cache, and dalvik cache
3)flash your chosen rom
kernels are a component of the operating system (rom) that controls how the hardware and software are running. basically it can improve battery life by control how optimized the system is running.
I have checked out the Rooting for Dummies, but I am still a noob and don't fully understand it all.
I loaded the ROM that was provided for me above. It loaded successfully, but I still cant find a 4g option. Any know what this is all about?
So let's say 4g does not work? It is "broken". Can you flash back to stock and 4g will be fine? Also what would be the easiest way to flash back to stock? (In case you need to send it in for warranty)
Edit: I am new to evo forum, Just needing to get some info before I jump into this.
Right, well, if you have a nandroid backup of a ROM where 4g worked, and you used RA (and chose the option backup wimax) or Clockwork (2.6.0.1 or up), then you can restore that nandroid backup. If you've lost 4g for good, though, as detailed above, and don't have a nandroid backup that includes your wimax keys, then you'd need to bring your phone in. I assume that is the case you are asking about. In that case, you'd need to unroot. There are instructions in the Rooting for Dummies sticky under the After Rooting section. If you rooted with unrevoked, you need to flash the S-ON tool to change S-OFF to S-ON. From there, you *could* run a RUU from your computer, but the preferred method is to use a PC36IMG.zip file. It's just a file you flash from hboot that is used to flash img files to whatever partition you want. In this case, the PC36IMG.zip file must contain all the img file contents of a full RUU. It will basically fully unroot your phone (once you have S-ON already, of course).
