HELP!!! - EVO 4G Q&A, Help & Troubleshooting

I followed online videos to install the Cyanogen nightly ROM, and after hitting reboot my phone didn't turn on...i held the power button and the "Sprint" screen comes on..and after that it just turns off again. Please help!!!!

If i pop out my battery, I can turn my phone on and get the htc Evo Screen, and then it goes back to a black screen...where the sprint logo will occasionally show up...and then go black again

I used the downgrading method to get to 2.1, rooted to 2.2 to get familiar with the process (unrevoked 3 or whatever it's called)...and I'm using the amon Ra thing...
(Clearly, I'm very new at this )

My friend did the same thing and had issues as well. Found out later his nand wasn't unlocked properly. When you boot into recovery, does it say s-off in the top left corner of the screen? Also what Eng bootloader version do you have, again this is located in the top left of the screen.

Is that what you're looking for?

Yep, you will want to start over again unfortunately. My friend had the same problem you did. You will need the .76 Eng bootloader. Go to unlockr.com and search for nand unlock evo. They have the instructions and files needed to fully unlock nand and get you to the. 76 Eng bootloader. After that, you should be good to go.

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?

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...

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.

Uh.....what exactly are you trying to do? PC36IMG.zip is the name given to files that we flash via HBoot. The contents of that zip file can be a vast number of things that change various objects of the phone. Post your question, what you're trying to do, etc. so that we can give you the proper links/files.
Otherwise you may be looking for a PC36IMG.zip that installs a new recovery and instead get one that completely unroots your phone and gives you S-on. So we need more details into what you are looking for.

Still need to be more specific.
You need an RUU to match your bootloader version, so that is needed.

Check what bootloader you have on your phone.
1. Turn phone COMPLETELY off
2. Press and hold volume down button while pressing the power button
3. A white screen will pop. This is your HBoot.
4. At the top it will tell you what version of Hboot you have. (i.e. 2.15.0001, 2.16.0001, etc.)
5. Take that number and post it in this thread so we can give you a file that will successfully flash to your phone.

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.

Wait what ??? My phone is rooted I'm using the express ROM ...
I been rooted for like 2 years now I just didn't notice that I neeeded S-off to flash hboots or radios. Which is weird because I used to flash radios and flash a new hboot with S-on . But now i can't update the bootanimation the PC36IMG.zip file or update the hboot.

This is no problem. I assume you changed your HBOOT to use the Anthrax kernel? Well, you should've downgraded your radio first, and then this would've been a LOT easier. But, since you're stuck at S-ON, now, you'll need to follow these instructions to fix it.

Hey captain I'm guessing you want me to do this? ?
It'll be okay . Boot into recovery and nandroid. You'll need it once you're done.
Just download this: PC36IMG_SuperSonic_S_Sprint_WWE_3.70.651.1_Ra dio_2 .15.00.11.19_NV_1.90_release_161482_signed.zip
Rename to PC36IMG.zip and put it on the root of your SD Card. Boot into Bootloader, and let it update your device.
Then, once it boots up, got into settings and enable USB Debugging, and go to unrevoked.com and select unrevoked3 to root & NAND unlock your device.
Then, you can switch your recovery to Amon RA, full wipe, and restore your nandroid.

You won't have to do anything with your HBOOT anymore after this. This will get you back to S-OFF, and at the end, you'll just restore whatever you're running now (unless you just want to flash something else).
You can flash the Express ROM, the Anthrax kernel, the updated radios, and you'll still be S-OFF.
Trust me, just follow the instructions. it's easy. You have to download and install the Froyo ROM so you can re-root with unrevoked. After that, you're just installing a custom recovery and restoring your nandroid.
Okay I got it but you lost me in the last part. Okay so I need to install a froyo rom right now then update the PC36IMG.zip and then let it boot. Go to settings and use the USB debugging and go to the website install the exe. Root the phone and nandroid it? .....
