Use unrevoked forever then go to hboot.. phone off power + volume down button till hboot is up. Check on top left to see s-on or s-off. Itlf it says s-off you are good to go and nand unlocked..

Help needed. Can't get out of bootloader.

I rooted using unrevoked and unrevoked forever, but I wasn't able to flash cyanogenmod, so I read up on NAND unlock and flashed the PC36IMG.zip from toast's method, but now it always restarts into bootloader and i cant get the os to load. Please help!
You should already have nand unlocked if you did unrevoked. All you you need is the eng hboot fix. Flash that zip in recovery , you can find it in dev section, then you should be able to flash CM hope that helps

This happened to me also. Go into recovery, run the mod zip again. If that doesn't work for you, you never saw me.
when i go into recovery it says E:can't open /cache/recovery/command
so i dont know how to flash anything
oh I see well try running ruu then just do unrevoked one click and youll be set just when you try to flash CM again after that make sure you flash hboot fix or it won't work.
Edit
Just read your post carefully lol czn you go into bootloader

There's a guide on rooting evo by regaww something. Download the PC36IMG from that post. Put it on card then just go to bootloader see if that will go through hope it does that saved me once

I had this exact issue after I loaded that PC136 file and installed it on my EVO. I wasn't able to do anything but load the bootloader. I finally had enough after 5 hours of no help, and found the shipping ROM and reinstalled the original ROM on my EVO.
i have since re-rooted and will not even dare to go back at this time to try that mess!
People can get you rooted, but they don't know how to get you out of a hole!

Look im not trying to be mean but searching is usually your best bet. I am willing to bet your answer can be found in the first 4 pages of this forum. Try searching ENG Bootloader .

I believe the unrevoked forever does that for you but you have to select it.
from www.unrevoked.com
unrevoked forever is a tool to set your Android phone's security level to S-OFF. The security level is a flag stored on the radio; when the flag is S-OFF, the bootloader (HBOOT) will no longer check the signatures of firmware images before flashing them. This allows custom firmware images to be uploaded, including unsigned boot, recovery, splash1, and hboot images (as well as official images that have been modified). When the system is S-OFF, the NAND flash memory protection is also reduced; this allows all partitions (including /system) to be written to while the operating system is booted.
Great response REM

What are you trying to do, could you be more specific? Unrevoked gives you unlocked nand, so i'm not sure what problem your running into?
I used unrevoked..tried to install cyanogen n I get a error message
Sent from my PC36100 using XDA App
are you sure unrevoked worked, sometimes you have to do it a couple times....do you have superuser permissions? I would make sure unrevoked is correctly installed...also redownload your rom and make sure the download is completed successfully, i never dl to phone, always to pc...
I have superuser..I used unrevoked
should I use unrevoked forever

Boot the phone into bootloader and you should see S-ON or S-OFF. If you see S-OFF you have nand unlocked.

Yes, that is what I said earlier a couple posts up.
Ya can't flash cm6 directly from unrevoked you need eng boot and amon recovery to flash it. You are most likely nand unlocked but trying to flash through clockwork. Easy fix is download Rom manager from marketplace then choose change recovery or whatever it says. I haven't looked at it for aong time then choose amon ra recovery. Then do another nand backup because clockwork and amon don't really work together. Then you should be able to flash cm6 no problem. Though having already done this I would personally suggest vaelpak over cm6 its almost all aosp and everything on your phone will still be functional. Plus its just as snappy as cm6 and I seem to get a far greater battery life with it.

If you want to be able to install CM6 you need the ENG Bootloader.

Okay thanks I'm gonna give it a try
Once that's done will I have to go back to clockwork recovery to restore back to current state

my guess would be when you rooted your s boot is still on. it has to be off in order to flash non sense roms. try flashing caulkios http://forum.xda-developers.com/showthread.php?t=745205
also go to settings then hardware information. what is your hardware version. once you have this power your phone off then turn it on by holding power down button and the power button this should boot you into bootloader. at top does it say supersonic blah blah blah s-off or s-on. also right below that gives hboot. 0.93.0000 is mine. once i know this i can help more. best guess is s boot is still on though.
Hardware version 003

So you completed the entire revolutionary process but it never gave you s-off but do you have revolutionary on the top of your bootloader?
Sent from my PC36100 using XDA App
I did complete the revolutionary process and it was on S-Off when finished but somehow I did something to turn it back on. Will I need to reinstall the program.. is there a quicker way of turning it back off?
BTW, looks like you have your Evo really set up! Any chance you can send me some links to set up mine? I'm running on Cyanogenmod 7 and I'm not completely happy with it.

Hey evo4gnoob, sorry about the delayed response friend. If you could still help me I'd appreciate it.
If I could recall this right, here's what happened: I was able to successfully root my evo4G through Revolutionary. I then tried installing the Cyanogenmod7 rom and ended up with a bootloop problem. I then flashed the Evo4G RUU to return it to manufacture settings. That process fixed the bootloop and installed Cyanogenmod7. I'm pretty sure that was what S-ONed the phone.

rowity and
I'm currently using hboot 2.10.0001 with radio 2.15.00.11.19, I was using hboot hboot 2.18.0001 I read that I could downgrade my hboot to 2.10.0001 that way I can use unrevoked3 to root the phone. I followed all the instructions and used the boot unlocker from htcdev.com to unlock the bootloader and use captain throwbacks method. When I installed the pc36img.img from captain throwbacks guide it seemed to mess everything up. I don't have a custom recovery but I should have one at this point right? I am so confused. I have s-off but it says I don't have root. I did have HTC sync installed when I tried to root it the first time and it failed so I had to uninstall HTC sync.
I can't remember but shouldn't it be "PC36IMG.zip"..? Been a while since I rooted my phone.
