Help needed. Can't get out of bootloader. - EVO 4G Q&A, Help & Troubleshooting

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!

Unrevoked isn't correct root look in the sticky topics to root correctly you need to boot into recovery to wipe when you do you select wipe the select dalvic catch and wipe data factory reset then select flash rom select cm then wait until its done then reboot you have installed cm I'll see if I can find I link for rooting

Yes you can should be fine unrevoked isn't full root i.e. root/nand unlock its just root you need nand unlocked so follow the tutorial from the beginning. Its like starting over no biggie the reason it said to use unrevoked because its a root method just not a full root method

Yes. If you want CM6 you need the ENG bootloader. Look in my sig.

Did you change kernals I heard there were gps problems with cm and kernals what cm are you running? Cm6 rc2 from 8_15 or the nightly? Also try putting the power control widget on you're screen and pushing the gps button on that that's been my fix in several roms some of them have it off by default

I just learned that the current iteration of BFS breaks GPS on many devices. BFS isn't part of CM, but if you're using one of the custom kernels with BFS and your GPS isn't working, thats the cause.

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.

Unroot

Hey quick question, what's the easiest way to unroot? Trying to help a friend, he is noob, and I don't know much about the EVO, any help would be appreciated. Thanks
Sent from my ADR6400L using XDA Premium App
Unrooting
1. http://unrevoked.com/rootwiki/doku.php/public/forever ; Scroll down to the FAQs, then download the unrevoked s-on zip. This places the security back on your phone, because rooting makes it s-off, and if s-on, quickest way to tell your phone was rooted.
2. Flash that file from recovery, then boot back into the bootloader [vol+down while turning phone on] and verify until its s-on.
3. http://dl.dropbox.com/u/19699565/3.70 RUU Zip.zip ; rename that file to PC36IMG, place on the root of your sdcard [not in a folder] then flash it in the bootloader. When the scan that normally does nothing, it'll detect that file. Apply the update then reboot. That's a stock 3.70 firmware file, it'll take you back to stock, unrooted, s-on.
Thanks, would it also work if he just went to updates, and got the new gb update, would u run into problems going that though if it even worked?

It's not hard. Just follow the "Guide Below for v2.3.3 builds 4.24/4.53/4.54 softwares to ROOT and unROOT revolutionary method" on his page. You will just need to run 2 PC36IMG.zip files from the SD card.
You don't need RECOVERY.
