I can't seem to find the guide for this. I know it can be done....or am I crazy. I rooted a friends phone this weekend. Tried to use unrevoked but it wouldnt work until I down graded froyo. He's rooted now. But still want to downgrade his hboot. And for the life of me I can't find the guide.

I think maybe this is what you want. It installs the eng hboot and amon ra recovery in one shot. The updated file with ra 1.8 is in post 18 in that thread. There's a guide in the first post. The only thing I can think to add is that you'll want to have a rom on the sd card ready to go. The reason being, it might boot loop after the install (mine did) and the only way I know to get out of it is to flash a new rom (or reflash the current one).
I can't post the link or i would just do that.
In the EVO 4G Android Development section, the post you want is called 'ENG bootloader (0.76 needed for CM6) extended fastboot commands'

Zikronix, I have just downgraded my HBOOT from .97 to 0.76.2000. (In fact done this a couple times both from 2.02 and .97). In case you still need this.. below are the steps.
1. Got my replacement EVO today (hboot .97, 3.29.651 build, 1.71 PRI)
2. Rooted it with this method using default (clockworkmod recovery)
3. Rebooted and flashed Amon_ra recovery (optional.. my preference)
4. Copied the correct Eng hboot file (renamed as PC36IMG.zip) to my sdcard, rebooted to bootloader, Eng hboot zip was flashed, I accepted update, done. Rebooted into recovery.
5. Flashed my favorite root ROM (this is necessary bcos the change on hboot does something funky to your existing rom, so you can only reboot into bootloader ... not sure why, some dev should be able to explain more)
6. Done.
Please help me. I just got it yesterday. My girlfriend was already complaining about me spending the money on it. Now when she gets home...oh boy. I was trying to change the color of the status bar. I went into system/framework, restarted and now it's stuck at the T-Mobile screen.
I just rooted it with adb. I don't have the Clock recovery installed. I don't have alot of time either. Please tell me my options. Here is my hboot screen.

Every phone i have had from the g1, mytouch 3g, vibrant, and now g2 it never fails to amaze me how people who dont know what they are doing manage to brick their phone in under a day. PROTIP READ learn what you are doing before you go in doing it so you dont screw yourself.
If you have the hboot menu and you seem to have s-off so you can restore official htc rom or a custom rom
Sent from my HTC Vision using XDA App
Yeah. Best bet would be to flash a custom recovery through fastboot and then reinstall the stock rooted rom or install a custom ROM.
And hopefully not make things worse botching the recovery flash

Yup, exacly what he said.. also, I don't think editing the statusbar from a stock is possible because its odexed, correct me if I am wrong though.. unless you really know what you're doing.. so now after flashing recovery, try again with a nandroid if you have yours if not with fastludeh's stock odex or deodex rom if you want to keep it stock.

You'll need to download this to your android-sdk tools folder:
http://koush.tandtgaming.com/recoveries/recovery-clockwork-2.5.1.2-vision.img
Then go into fastboot and type
fastboot erase recovery
followed by
fastboot flash recovery recovery-clockwork-2.5.1.2-vision.img
From there you should put a custom ROM (probably CM6 or enomthers) or rooted stock as advised above on your SD card, boot into clockwork, wipe system/data and install the ROM (and gapps if you do CM6).
And please remember: nandroids are your friend

And just so you know, your lucky that you flashed the ENG HBOOT, without that, you would have been screwed.
EDIT: Oh wait, it says SHIP S-OFF, shouldn't it say ENG S-OFF if you had the ENG boot loader? Did you even flash the new HBOOT?

Wait, does he have engineering HBOOT installed? The HBOOT screen he listed says SHIP. Without the ENG HBOOT, he won't be able to fastboot the ClockworkMod Recovery.
To the OP, you probably will have to flash back to the official HTC ROM. See this thread: http://forum.xda-developers.com/showthread.php?t=788489.
And yes, as others have stated, you should make a nandroid backup prior to messing with system files. You cannot edit the framework without DEODEX-ing the system first.

Yeah I just noticed that and edited my post about 1-2 minutes ago.
Ok, I entering these commands in cmd window right? Just like I did for rooting, right? If so, it said failed, not allowed when I input fastboot erase recovery.
The guys above were right. I saw s-off and assumed you had the eng-hboot. Sorry. At this point you're going to have to flash an RUU and go back to stock and then try again.

Yeah ummm you might be screwed, we assumed that you flashed the engineering HBOOT, and only with the engineering HBOOT can you use fastboot to save your self and it seems like you don't have it. I'm not sure what to do now, I think some one said that you might have to flash the stock ROM but I'm not sure how. Wait around for some other guys to help you out, they know more than me with this stuff.

Are you sure he can do that? Because theres like a sticky in the dev section of the forums saying NOT to do that unless you know what your doing or only if you flash the EXACT same ROM that came shipped with your phone, or something like that.
EDIT: And if you do have to flash an RUU, could you please explain how? I would like to know how just in case I screw something up(which I probably won't because I have been on my computer searching the forum, asking for help and to double check that what I have learned is correct and what to do if something bad happens for the past week or two) and I can also use the information to help other users.

That was a warning because if you had S-Off and root it would put S-On and remove root. It was an issue because for a while it was impossible to root the DZ's 1.72 RUU but this has since been worked around and doesn't apply to the G2.
Ok, guys Im not an idiot. I previously had a HD2 and had no problems...just rushing to get my phone right before I go out of town for the weekend. So, whatever I have to do to get it right.

You might be right.
Ok,... So you have gone into your Hboot screen, select fastboot, then it says Fastboot on the screen yeah? Do:
fastboot devices
in cmd, do you get anything?
i updated to 2.33 now when i boot into recovery i get a phone with a red triangle. The only thing I can do is remove the battery to reboot. What do i need to do?
Thanks,
Did you update via the OTA from Sprint? Are you rooted?
Yes updated OTA from sprint and yes Rooted
If you took the ota from sprint you're no longer rooted.... Sorry... But to stay rooted you needed to flash a rooted ROM...

Okay, well if you updated via the OTA then you are more than likely now unrooted. You are getting the red triangle because you don't have a recovery anymore. Unless I am mistaken, you should still be able to get into the hboot screen though. Are you holding volume down and the power button?
Yes i can so do I need to root again

Well if you can get into hboot it should say S-OFF or S-ON near the top. If you are S-OFF you may be able to reverse the not being rooted issue. But, if you are S-ON you are out of luck and will have to wait for someone to find a new exploit for rooting the new update.

If your bootloader is S off still, all you need to do is flash a PC36IMG of a recovery image. From that point flash a new Rom. If you want to be on the ota update, then just flash a rooted version, which would've been way easier for youth do in the first place.

Put this on root of sd http://files.androidspin.com/downloads.php?dir=amon_ra/RECOVERY/&file=PC36IMG.zip
download and dont extract just drag it to sd card and go to bootloader it should say update press vol up for update then when its done uploading you will have amon ra it only works if youre S-OFF

You DON'T want s-on, so just place the zip posted above me in your sdcards root and flash it in the bootloader.
yes S-off I place the file PC36img.zip on SD now how do I boot without recovery
I am sorry "Flash" without recovery
boot into bootloader then go into fastboot and it should start updating then when its done u have amon ra and can flash a rom from there but first put tht file on sd card
Apparently, taking the OTA while staying rooted keeps you S-off.
Makes me laugh even HARDER at people who unrooted to take the OTA

id say hit the irc for a faster response from someone who knows and ask them if you can use newkidds 1 zip to get your old hboot back, but keep in mind newkidd now has like 3 ruu files the old one with the .93 hboot and one with the .98 hboot and one with none I think

I flashed the .exe so i dont have access to clockwork recovery any more, To flash zip files. Probably a big mistake until a perm root solution is found.

You won't be flashing an exe with the ruu program on your computer, it should just return you to 100% old stock

i just need.
I just need to find one that will revert me back to stock with .93 hboot so i can start over from scratch. The v1 version will not allow this due to being the wrong hboot when it does itks check...
I have unrooted my phone but it still reads S-OFF. How can I change this to be S-ON?
How did you root? What hboot version do you have? Why are you unrooting? If you give more information, you're more likely to get answers.
If you rooted with unrevoked, you need to flash the s-on tool. You'll need to reflash your recovery. You may need to downgrade your radio for the s-on zip to take. You may need Amon Ra to do this. Once you've downgraded/s-on, flash the RUU again to get rid of your recovery.
If you rooted with revolutionary, there are several threads about unrooting it. Check those.
If you're taking its in for repair, you may not need to be s-on. I'd leave mine s-off, but that choice is yours.
