[Q] revert back revolutionary s-off to stock hboot - HTC EVO 3D

Hi,
My Evo 3d GSM device was S-OFF by the Revolutionary method.
All work fine.
But for garanty purpose, l've already restored boot_signed and system.img from stock rom.zip
Can i restore original recovery with:
fastoot flash recovery recovery_signed.img ?
And Restore stock hboot with:
fastoot flash hboot hboot_SHR_U_1.53.0007_20120522_signedbyaa.nb0 ?
Thank before,

If you really want to go back to stock, run the ruu for your region/carrier. It will leave you s-off, but everything else stock. You could go 100 percent stock by going back to s-on first. EDIT: After! See ramjet's post below.

Running the RUU should restore the default recovery and leave you s-off if it is going in for warranty work don't forget you want to be s-on (fastboot oem lock) after running the RUU.

That's the command to relock after doing the HTC unlock. The command to set S-ON is "fastboot oem writesecureflag 3" and should only be run after the RUU is flashed and the stock bootloader is restored. If S-ON is set while a modified bootloader such as ENG, Revolutionary, or Juopunutbear is installed it will brick the phone.

So ramjet: if s-on, you lock then run ruu. But if s-off, you run ruu then lock if you wish. Is that right? I know it's a different kind of lock, but i didn't realize order mattered going s-off to s-on.

Yes, those are separate S-OFF's. The bootloader unlock (hboot S-OFF) is different from the radio S-OFF. This post from the MeanROM ICS thread has an explanation by Unknownforce, the developer behind the the hboot 1.4 downgrade method for radio S-OFF.
The "fastboot oem lock" command will undo the bootloader S-OFF, which is required to run the RUU.exe for users that are radio S-ON. Users that are radio S-OFF can run the RUU.exe without any special considerations.
Once the RUU.exe is run and the stock bootloader is installed, the phone will be bootloader S-ON regardless of the radio S-OFF status. To run fastboot commands like "flash" and "erase" the stock bootloader needs to be unlocked by the htcdev method or a custom bootloader modified to support those commands needs to be flashed, which requires radio S-OFF.
After installing a custom bootloader, setting radio S-ON via the "fastboot oem writesecureflag 3" bricks the phone because the bootloader is not signed by HTC and that is not allowed with radio S-ON. Therefore a stock bootloader needs to be reinstalled before setting radio S-ON and the easiest way to do that is flash an RUU.exe.
Hope that makes sense.

Hello,
After all your explanations, I was reassured to install "RUU_SHOOTER_U_ICS_35_S_HTC_Europe_3.28.401.1_Radio_11.77.3504.00U_11.25.3504.06_M_release_262714_signed.exe"
Unfortunately it did not work: probably due to the absence of CID (HTC__203) of the revolutionary HBOOT.
So I took the rom.zip file in the% temp% directory and I renamed PG86IMG.zip. I pushed on my sdcard.
A reboot in the bootloader and the EVO 3D has successfully installed the ROM with firmware radio, recovery, system ... in short, everything
Now my HBOOT is 1.53.0007 HTC, it does not show revolutionary, but it is unlocked and S-OFF
Now I think it is acceptable to send like that. What do you think?
In fact I've not said what the problem was my phone: After installing a ROM that had the good idea to turn xLOUD (I think that's it) it has blown me the speaker (communication only)
Thank you again for your help

Everything was fine in the end? I'm in the exact same situation and I'm installing PG86IMG.zip as we speak. Did HTC see anything wrong with your phone?
