This took me all day to figure out so I'm making a guide. The 2 Big problems I had were getting the S-on patch to work and the newer Hboot that came with gingerbread refusing to downgrade to an older PC36IMG.zip.
The main reason I wanted to return to stock was for a repair, last time i did everything except s-on and the guy noticed it and black listed my esn.
Make sure you are prepared before you continue! Once you flash your radio your phone wont boot into the OS.
First, you need to flash an older radio for the S-ON patch to even work. I found flashing EVO_Radio_2.15.00.07.28.zip worked best. Do this in your custom recovery
Follow djR3Z's guide to turn S-ON but do not go past step 7!
Download this file I got this off a youtube video for the incredible and replaced the files with their EVO specific counterparts
Open the zip and move flash_image and mtd0.img to your sdk/tools/ folder
boot into your custom recovery and mount /system/
open up a command prompt in your tools folder
(in windows7 hold shift and right click on /tools/ there will be an option to "open command window")
Run the commands in the commands.txt file. FYI you can paste into command prompt with right click.
adb push flash_image /data
adb push mtd0.img /data
adb shell
chmod 777 /data/flash_image
cd /data
flash_image misc mtd0.img
exit
adb reboot oem-78

After this you can move your stock PC36IMG.zip to the root of your SD card and reboot into your Hboot Bootloader. If everything was done correctly it should now accept PC36IMG and downgrade to stock.
Great job! Do you think there will be an easier way in the future? I don't think I would be able to do this.

If you run the 3.70 RUU while still s-off, will it replace the hboot with an older version? It seems like it should, but I'm confused by the 6.16 hboot.
I haven't actually ran revolutionary, so this is all theory, but I thought unrooting/s-on would work like this:
Run the RUU for 3.70. I don't have much experience with RUUs, but if they don't include radios, you would then need to reflash recovery and downgrade the radio. After reflashing etc, then flash the s-on zip. Then rerun the RUU for 3.70 to get rid of your custom recovery, or run the RUU for 4.24, since once you're s-on you can't downgrade & every RUU will be a downgrade from 6.16 hboot.
Now this may be entirely wrong, but I was just curious if it would work. I've been rooted for a while, and unrooting and s-on would be much easier for me. Even though it sounds like a pain, it still sounds more noob friendly than the version in the OP.
Either way, great job on putting this together. I know that a lot of people are curious about unrooting from revolutionary, so hopefully you've cleared some confusion.

I can't get this step to work, try as I have to get S-ON back, it won't go. Doesn't the Revolutionary HBOOT prevent this from working?
The unrevoked-son zip flashes fine, and says it worked, but I'm still S-OFF. What did you do to get it to work?
@plainjane
HBOOT will not update to an older version. If that were possible, the GB OTA wouldn't have had to be rooted at all, since everyone would've been able to downgrade to a rootable HBOOT version.
It's that fact that makes me wary of this method working at all. Can the steps after the "S-ON" portion be completed (which I assume finds a way to downgrade HBOOT), and then run the S-ON tool & flash the stock PC36IMG? I think that's what I'll try now, since I can't get it working in the order specified here.

You can downgrade via RUU if you're s-off. My suggestion was to run the RUU while still s-off, because s-on won't allow you to downgrade. Or, if the RUU won't replace the bootloader, then flash an older hboot.
Then, if you're still s-off, flash the s-on tool. I don't know if this root method uses unrevoked forever or if it's just an always s-off hboot. I do know that it's a different hboot version.
If anyone has a chance to try to run the 3.70 RUU and see if it downgrades the hboot, I'd like to know. If it doesn't, but the RUU completes, then you should be able to flash recovery and then flash an older hboot - I believe 2.10 is the one that shipped with 3.70. Mine is 2.02, and I never updated to 3.70 (I believe it was 3.30 when I rooted).
Again, it's just a theory. If I get curious enough then I may unroot and update just to try revolutionary and try to unroot again, but I'd rather not get stuck with a horrendously obvious 6.16 hboot that can't be replaced/unrooted if I don't have to.

What I was saying is, at least with the Revolutionary HBOOT (6.16), it will not downgrade, either using the 3.70 Froyo RUU or the 4.24 GB RUU or PC36IMG.zip files flashed through Fastboot. It bypasses the Bootloader update every time.
Have you somehow gotten HBOOT to downgrade while S-OFF?

Hboot 6.16 will not downgrade or flash S-ON currently.

I wasn't sure about the answer to this question, so I thought I'd just go to Q&A and ask. I searched and didn't find anything on this specifically. I'm a bit worried about using the latest RUU since the whole 2.02 HBoot thing (though I'm not sure if it would update older phones to that version). I was wondering if I'd be able to use the recovery to flash an early rooted rom and from there use an RUU and unroot it to that earlier version.
Sorry if that doesn't make a whole lot of sense, I'm just wondering if I can trick the RUU into letting me install an old version. A botched unrooting left me with the 0.93 hboot instead of my usual .76 eng hboot.
I don't think that this will work for ya, you need to downgrade your hboot. From my experiences by downgrading my hboot i was able to flash older ruu files.

Oh well, I'll just flash the latest PC36IMG.ZIP. I found it on the 2.02 hboot thread. It doesn't really matter, I only need to unroot this thing long enough to have Sprint accept it. It's been rebooting so much lately that I can barely use it for longer than 30 minutes. This was my last resort after wiping repeatedly, changing SD cards and other things.
just remember to flash the Unrevoked S-On tool too.
Need to return my leedroid 2.2.2 to stock.
Somehow i have lost eng s-off. Tried to install different radio but it wouldnt allow me, as bootloader says ship s-off. So have been advised that i need to downgrade again, and go through the s-off / root process again - Here
How do i go back to the easy rooted 1.32 stock again. I have an RUU for that version, but its not seeing the phone. Found a workaround - Here - but it only got so far before the phone froze, and the installer said it couldnt find phone.
Thought for a minute i had bricked the phone, so after crapping myself, decided to seek help here on how to return to 1.32!
Look at the rooting tutorials for 1.72.
AFAIK, you need to change the version number for this to work (to allow downgrade).
Do you have ship s-off or you do not?
You can't flash a radio because you don't have eng s-off, therefore no fastboot commands.
Just flash any ruu you want using the pd98img.zip method and all shall be stock. Launching an ruu update from your pc is notoriously unreliable and I would never recommend it.
Here is a guide to the method if you have no idea whet I'm talking about.

Had tried to flash pd98img from my sd card but kept getting some error (cant remember what it was now, will check again later). So thought maybe needed to use the RUU to go back to a stock ROM, but was just guessing at that. Will have another go at PM98IMG when i get home from work.
You have Radio S-OFF, so you do not have to use the downgrade guide. Just flash 1.32.405.6 stock ROM using PD98IMG.zip (get that from the downgrade guide), and then you can use my Radio S-OFF tool to go S-ON. You can also check the S-ON instructions in my tool thread.

Thanks. I tried last night to do this (though i was going to go the full downgrade route) but couldnt get it to install. But i was selecting the zip from sd card, which i think is wrong? (hboot will pick the zip up itself?)
Can you briefly explain to me what S-ON is? Im a total noob here, and always thought we were looking S-OFF to flash Kernels, Radios etc.
I owe you a thanks. Already handed out 5 today and cant give any more!

hmm having problems. Have got back to stock ok. But when i try to run your tool i keep getting connection error. Have tried in XP and win 7, and from root of drive as some others have suggested worked for them. Any ideas?
EDIT: Think i have it sorted.
Hi!
My phone broke and now I want to try to get it fixed with warranty. I'm not sure if warranty still is available if I use root so I want to unroot.
I have read that all I need to do is flash the RUU, but which one? http://forum.xda-developers.com/showthread.php?t=824357
And what will flashing it do? Will it remove CWM and everything else I was using to root? I remember that I flashed radio 2 times, had S-OFF and E-ON.
And then I will simply run System Update? Because it seems that RUU are firmwares that phones are shipped with.
yea, just flash a RUU.
Make sure you install the original RUU for the type of your DHD (i.e. WWE, Voda,T-Mobile...)
and if your phone is S-OFF, make it S-ON - S-OFF / S-ON GUIDE (guide for S-ON is at the end of the 1st post). Go into bootloader and make sure you have S-ON
--your recovery will be restored to original HTC recovery
Oh, but which RUU I need to flash? I remember I needed to do a downgrade and I think it was 1.72.405.3, not the R2, but I'm not sure.
Well, when you had your phone, was it branded?
if so, you need to find a brand-specific RUU.
If not, then WWE RUU is fine.
i would suggest the 1.32 FW (because S-ON requires temproot from Visionary+), then follow the guide to S-ON
What about radio? I have flashed the leaked gingerbread radio, wouldn't they be able to see that I have flashed a newer radio? Or the RUU flashes radio also?
RUU flashes radio too. But after flashing the RUU have a look into the bootloader, the device might still be S-Off. For S-On you need to root again and Use the easy radio tool to make S-On again. Then use the RUU again.
It still was S-OFF, but used Visionary and Easy Radio Tool to get S-ON. A brand new phone
Thanks!
Does it work the RUU to flash even if I come from an ext4 ROM (ARHD 5.1.9)?
Or do I need to format first by cwm 3.0.2.6 so that it is ext3 again?
No one any advice?
I've done a lot of reading and see where Alpharev has a hboot downgrader but does this work with CDMA version BravoC?
I rooted using Revolutionary after having hboot 1.06 for a USCC Desire. Phone is out of standard warranty but I need to send phone in for repair under extended warranty. When I flash 2.2 RUU it cannot roll back hboot version.
Thanks!
I still haven't found anything. Thanks for the help.
what was your original Hboot number?
see alpharev page, if your model is supported try this -
flash HBOOT bravo_downgrader and right after that run appropriate RUU wich contains default hboot to protect extended warranty
as a result of this process you become S-ON again with stock Hboot
i think this may work even for CDMA version but i am not 100% sure
google it and you will find the answer
Here is about GSM Desire...
Actually I just use revolutionary to s-off my phone and it work. I test several new ROMs right now, then I try to flash stock ROM back when found this thread. I can flash the RUU HTC Froyo successfully. but...
the hboot is not overwritten. it still revolutionary. I am very sure the stock ROM I use contain hboot. because I can see it upgrade my hboot from 0.8.000 to 0.93.0001 during I flash this ROM before I s-off it yesterday.
revolutionary claim that we can get the original hboot if we flash stock ROM that contain hboot but it not working for me. maybe you need to tell them about this.

[8]STILL S-OFF AFTER RUU
"I want to return my phone for warranty, I used a RUU but I'm still S-OFF"
Cause:
- Alpharev's Hboots are write protected, so that they can not be overwritten by a RUU
HOW TO S-ON
METHOD 1#
[STEP1]- Visit Alpharev and download the "Downgrader"
[STEP2]- Flash the downgrader over fastboot. This can be done with Android Flasher, cmd, or fastboot commander (Note: android flasher is the only program that does not require third party software such as Android SDK or Java JDK)
[STEP3]- You should now notice the title on the bootloader screen is "Alpharev Unlock", run the RUU again and you will have S-ON'd your device.
#METHOD 2#
[STEP1]- Instead of running the RUU again, and putting your phone at risk once more, you can simply upgrade just the bootloader manually, with the PB99IMG.zip method.
[PHASE1]- we need to extract rom.zip from the RUU.
[P1/STEP1]- Run the RUU (BUT DO NOT PLUG IN YOUR PHONE OR CONTINUE), move it to the side as it cannot be minimised.
[P1/STEP2]- go to start menu, and use the "run" feature. Type in %temp%
[P1/STEP3]- select "date modified" to "today" (to make it easier to find). There are should now be 2 folders with long names of random characters.
[P1/STEP4]- search the folders for rom.zip and extract it to the desktop.
[P1/STEP5]- delete everything EXCEPT "hboot_8x50_0.93.0001_20100810.nb0" and "android-info.txt"
[P1/STEP6]- rename the zip to PB99IMG.zip (make sure it is not PB99IMG.zip.zip)
[PHASE2]- now we need to update the bootloader
[P2/STEP1]- put the file in the ROOT of your sd-card (not in any file or folder) and boot into bootloader (poweroff, hold VOLUME DOWN and POWER). After a few seconds, you will be prompted to update bootloader. Select Yes. DO NOT INTERRUPT THE PROCESS, OR YOU WILL BRICK YOUR PHONE.
[P2/STEP2]- Once the process is finished, you will now be S-ON.

i have tried every method i can find to get s-on after root with revolutionary. i have flashed the s-on zip and all it does is get rid of the red bar that says "revolutionary". it still say s-off. ive done it from a custom rom and a stock rom. done it through flashing and done it buy naming the zip pc36img it installs successfully but still shows s-off. any help is appreciated
#1. The s-on is NOT 4 revolutionary. Search for how 2 unroot revolutionaty root. Its the thread with a whole bunch of ??? at the end of the title. That should lead u toward the light.
