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.
hi!
i found a shop in my area (slo) to unlock my phone. but i'm a bit confused. if i get my phone s-off-ed, as i understand this means full system root, which should men i should be somehow able to flash clockwork mod and then custom roms. this should be done by downgrading to 2.1 and hboot 0.8x.
i found a video tutorial on downgrading here:
http://forum.xda-developers.com/showthread.php?t=981765
and my question: shouldn't i be able to flash clockworkmod directly (without downgrading), since i will have my phone fully unlocked? if possible, how?
I think the best is after the s-off, install and older RUU, then use unrevoked 3.14 thats the most easy and i think the safest way
Most efficient way

Hi
I have rooted wildfire with s-off (xtc clip) and Hboot - 1.01.0002 . I tried the above method but fastboot wont detect the zip file and says not found. I am unable to install clockworkmod using rom manager, whenever i do, i get the red traingle of death.
What to do now ?
Please help...
u donot need to downgrade with an RUU. and further doing so may make ur phone S-ON again (im not sure about this).
u have a simple process.
u can flash any "recovery image" via fastboot mode.
and that's all, after doing that u can flash any rooted custom rom from that recovery.
getting to S-OFF is an expensive task yaar (as far as now). try to keep it in S-OFF permanently.

have u done the "PC49IMG.zip" process with the file in the above link. it is the process for flashing clockwork mod "recovery image". once this is successful, then u can install any custom roms from the CWM recovery.
note: donot do the PC49IMG.ZIP process with any outside file (excluding the link above). if u do that, u might loose the S-OFF
Alternatively, u can flash other recoveries also (i dont know any others)
I got it eventually, I downgraded using ruu rom to hboot. 80 rooted it again and now have 2.3.3 over it
Thanks anyways ..

How will you lose s-off by flashing a PC49IMG.zip? XTC Clip wipes the secuflag in radio NVRAM, no way of getting it back via a normal update.

I've installed the revolutionary for the S-off, rooted and have a Nandroid backup thanks to the excellent guide:http://forum.xda-developers.com/showthread.php?t=1029318
Since somebody said the RUU rom is somehow different from the stock rom, so if I flashed a custom rom, the only way for me to get into the stock rom is flashing the backup in Nandroid.
After that, I can flash the fastboot into S-on Hboot 1.01.0001 thanks to this guide:http://forum.xda-developers.com/showthread.php?t=1160251.
But it is still not the stock Hboot 1.01.0002(only flashing RUU can do so). Does any method allows me to flash the Hboot into 1.01.0002 version and also unroot the rooted-Nandroid-backup, so my phone can be completely restored? Thank you so much!
An RUU is necessary to remove the Clockworkmod Recovery (Custom Recovery which allows you to flash stuff). That is the only reason why an RUU is needed to back to a completely stock state.
You can replace the HBoot file in that 2nd guide using any HBoot. So, you can extract 1.01.0002 from a RUU/OTA you know carries it, and replace the file accordingly.
Replacing the Stock Recovery should be possible without an RUU - BUT, it will need someone to extract and verify it. Till that process is done, I guess its the only way to completely get back to Stock.
Or are there any method to upgrade the Hboot 1.01.0001 into 1.01.0002 by extract the boot.img from the RUU?

Oh...I forget the most important part (remove CWM), thank so much!!
Here's what I propose:
- Restore your Nandroid Backup of your Stock ROM. This will give you the Stock ROM.
- Extract the Recovery.img from an RUU. Flash this using flash_image or Fastboot. This will remove the Clockworkmod Recovery and get back the Stock Recovery
- Extract the HBoot 1.01.0002 .nb0 file from an RUU/OTA, and flash using the guide above. This will remove the AlphaRev HBoot and replace it with stock.
These 3 steps should help you get back to a completely stock system. WITHOUT touching an RUU.

Thx!
But the Nandroid backup require root permission, will the rooting permission be still exist after getting back to the stock ROM? how can I Unroot it?
Yes which is why in the 3 steps I posted, Nandroid Backup comes first. So once you restore that, then you have the stock ROM, But, you have Clockworkmod and Revolutionary HBoot.
To remove Clockworkmod, and get back the Stock Recovery, Extract the Stock Recovery.img from an RUU and follow this:
http://forum.xda-developers.com/showthread.php?t=974590
Now, you have your Stock ROM and a Stock Recovery, You just have to remove the Custom Revolutionary HBoot. Again, extract the HBoot 1.01.0002 .nb0 file from an RUU, and follow the same guide you already linked, to get back to S-ON.
Thus, you can revert back to Stock completely without running an RUU and losing your data,

Nandroid backup and nandroid restore will not require root permissions.
And your question depends on whether (or not) you have rooted and then made nandroid backup.
And if you have to unroot it, do it before flashing hboot. Because once s-on is made, it is bit difficult (nearly impossible on hboot 1.0x with stock recovery) to unroot. Use super one click or gingerbreak.apk to unroot .
[In short, unroot = removing su binary from /system/bin (or) /system/xbin ]

Hi, everyone who have been waiting for a way to downgrade their HBOOT so that they can get S-OFF, cause they upgraded to the Official RUU Rom... I think I found a solution for you!
Also give you permanent ClockWork Recovery!
I haven't test it on any other Slide, cause I have only one. So, sorry if it didn't work for you.
Here is what I did, in case you're wondering, I downloaded the Official RUU from HTC Support website, extracted the 'rom.zip' file from Windows Temp folder that it creates, replaced the newer 1.02 HBOOT with 0.52 HBOOT, that I got from 'ESPRIMG.zip' (the Stock rom).
And also replaced the recovery.img with ClockWork Recovery img file.
Then I just renamed the 'rom.zip' file to 'ESPRIMG.zip'
Put it in the root of my memory card, powered off, rebooted into BOOTLOADER, and it detected the file and asked me if I wanted to update, I chose YES, and it went on without a hitch. Next thing I knew, I had 0.52.0000 HBOOT, with permanent ClockWork Recovery(so I dont have to use 'update.zip' anymore), and also the Official Latest 2.15.531.3 unmodified rom, (I like stock Espresso, that's why I bought it ) but you will LOSE ROOT but SuperOneClick method works for me to gain root - http://forum.xda-developers.com/showthread.php?t=803682
Method:
1. Download this 'ESPRIMG.zip' file - http://www.mediafire.com/file/cuemg74en7kk0a3/ESPRIMG.zip
2. copy/paste it to your memory card, in the root, not on any folder.
3. Make sure your card formatted to FAT32 file system, or it won't detect it.
4. Do a Nandroid BACKUP, if you can, cause I don't know if this will work for you. But it will wipe all your data and setting. SO BACKUP!
5. First you need to wipe data and factory setting, and wipe cache and wipe davlik cache (Otherwise it bootlooped for me). So boot into recovery first!
You can do that by going into BOOTLOADER first then selecting Recovery ( for that remove memory card from mobile or else it will start update) or if you have ROM Manager then you can use that to reboot into Recovery, any recovery will do stock or clockwork.
6. Ok, so after Wiping from recovery. PULL battery, then insert back the memory card with ESPRIMG.zip file on it. Reboot into BOOTLOADER, and apply the update.
It should do a reboot automatically to downgrade the HBOOT.
You will see the change if it worked. After applying the update, reboot phone normally.
And if all done correctly, you should have 0.52.0000 HBOOT, and also a permanent ClockWork Recovery. Now you can root by using SuperOneClick method. And also get S-OFF (I didn't need it, cause I have permanent S-OFF! , at least that's how I explain it)
Im guessing it worked for me because I have a factory unlocked S-OFF HBOOT from HTC. Because, to try this out first, I updated my phone via the OFFICIAL RUU from HTC Support Website and it showed S-OFF on my 1.02.0000 HBOOT.
Then I tried this method and it did downgrade my HBOOT and I still had S-OFF without doing the AlphaREV method.
So I guess I have a kind of permanent S-OFF??! :S :?
Hit thanks if it helped.
I am no developer but I am learning
Any feedback would be appreciated.
And yes, my major is CS and I LOVE IT!
any one test this yet?
If i try this and it does not downgrade my HBOOT will my phone be bricked? Will I lose root? I would love to try, but would like a little certainty.....

I don't think that you phone will be bricked, it would just not downgrade it but the HBOOT will remain. Yes you will lose root, but that can be gained easily by SuperOneClick Root Method.
I not certain myself about the brick. Flash at your own risk.

I'll be trying it once the download finishes for me. I'll update you guys on whether or not it worked for me.
I'm using a full stock phone btw, factory reset and blank sdcard as well. Hopefully this works for me.
UPDATE:
Looks like this was a dud.
I applied the update 3 times to my phone, but my Hboot still didn't downgrade. It's still on 1.02.0000. Also didn't flash the permanent Clockwork Recovery that we were hoping for either.
I'm guessing your permanent s-off is what let you use this successfully. So for anyone who has S-OFF already this would probably work fine.
On the plus side, it didn't brick me =)

Well thanks for the feedback, yes I think its the permanent S-OFF too. So does that mean I have a phone that was permanently UNLOCK my T-mobile or HTC it self for testing purposes? Is there some way to use this to unlock that 1.02.0000 HBOOT?
any updates on how to downgrade?
i need to downgrade my Espresso, i have the latest official t-mobile update.
i have already followed instructions very carefully missing no details.

Ok so i recently just updated froyo to gingerbread beacause i was tired of it and i was perm rooted and now im not im version 2.3.4 and i have still have s-off anyone please help me get rooted without downgrading?!
how did you "upgrade"?
What's so damn urgent? The world will end (again...) if you won't be rooted?
And if it's so damn urgent - how about spending 5 min on Google-searching to discover the answer without even opening a thread? Hint - there's "root for s-off" thread, more than one.
To root you have to downgrade.... Did you use pd15.
This is NOT urgent. Damn people

You need to learn to use Google. You got yourself into a situation you don't know how to get yourself out of because you decided not to do your research. Now you are refusing to research again. I will give you a link to a 5 minute adb/fastboot install, but you get to use Google to figure out how to use it.
http://forum.xda-developers.com/showthread.php?t=928370
Just one additional clarification:
fastboot won't help him, since he's on stock HBOOT that will refuse fastboot.
What he can do, is to look for "root for s-off" thread, that has the required PD15IMG and instructions to get ONLY the engineering HBOOT and custom recovery in place.
If he won't find it - means he doesn't need to be rooted in first place.
From the custom recovery he'll need to find and install Superuser/SuperSU ZIP. And it's described in the thread.

You must have gotten S-Off with gfree. A PD15IMG.zip flash won't turn the security flag on when you use gfree.
Also, Jack_R1 was very helpful as well. He simply wants people to do their research and know how to solve a problem before they run into it, as do I.
Hopefully, now you know what happened, why, and how to fix it in the future if you or another person get into the same situation or a similar one. Good luck, and enjoy your phone!

-Get Rom Manager and flash clockwork
