[Q] How to downgrade HTC One Developer Edition (US) from firmware 1.29.1540.17 to 1.2

Hello,
I have been researching here to find a way to downgrade to a previous version of a firmware so that I can S-Off, and to no avail unsure how to do it myself using either use Moonshine or revone.
The reason I wish to do this is that I want to install Google Play edition and of course the necessary info to install it.

If I'm not mistaken the ROM firmware is irrelevant as to if you can root or not, or get-S-OFF. The most important factor for S-OFF is the bootloader version. I haven't seen any threads about getting S-OFF on bootloader 1.54.
Reboot to your bootloader (turn device off, hold volume down and turn device on). Check your HBOOT version there. If it says 1.54, then the only possible solution is to search for an official HTC RUU with a lower HBOOT version. However I do not know if this will actually work.

Alright. Assuming that works, is there a way to reflash?
[Edit] Just checked my bootloader it says that I have 1.44. However I have tried both Revone and S-off with no success

Don't really know what you mean by reflash? Returning to the newer HBOOT (1.54)?
If that's the case, once you're S-OFF you can update the HBOOT to 1.54 and S-OFF will still be there. There are some threads in the development section about upgrading the HBOOT. I used these myself without issues.
As for the official RUU, this will probably be a Google search. I haven't seen a thread around with these files.
Keep in mind that flashing an original RUU will result in loss of root and custom recovery. You will need to re-root after flashing the RUU and reflash a custom recovery.

A little bit off topic here but ..if I am s- off already and I were to use a stock ruu on my phone all that I will I loose is the recovery and root?... So after I run ruu my device will still be s-off ?

I think so yes, but I'm not 100% sure. You may find the answer, or ask the question in the hboot update threads or s-off threads. I haven't flashed a RUU myself in years.

What I mean to say is that once I have found one with an older HBoot, how do I go about flashing that so that I can do one of the two S-Off procedures?

Ah ok. The RUU should be a windows executable. Just hook up the phone to computer, start the RUU and follow the on-screen instructions.

Here's an article about flashing a RUU: Flash RUU
It has a link to a website which contains several RUU files to download: HERE

I was s-off with stock unrooted locked 2.24.401.1 firmware (ruu'ed by repair center)and tried to use revone to unlock again but it would fail, then I downgraded to hboot 1.44 (I could still do this because I was s-off already) but revone would still fail, then I decided to properly downgrade to 1.28(or was that 29).401.?? with an ruu and was able to use revone again to unlock my bootloader, so hboot is not the only factor for revone to be succesful...
downgrading hboot and other system partitions, except kernel rom radio and recovery, is not possible if you are not s-off already....

At this point I am looking at installing a custom recovery, though from what I am reading I may not be able to do that without S-OFF, so I am stuck if this is true.

S-OFF is not needed for root or custom recovery. You do need an unlocked bootloader though. On other devices S-OFF was needed to flash radio's or kernels through recovery, but from what I have read the One can flash kernels in recovery without S-OFF

So I have gotten TWRP on there, however I have been unable to flash a previous firmware, to downgrade, getting the error message, Unable to open zip. My guess is that S-On is stopping this process even in a custom recovery. Is there a recommendation as to how I can achieve S-Off?
Also There is something I have been thinking about it, and if I were to follow the steps here, with execption of the flashing the RUU through fasboot, could I flash the RUU through TWRP instead?
[Edit] Could I install a custom ROM, S-Off through the ROM, then follow the steps in the link to flash the RUU?

All you can do is flash your backup, restore the stock recovery and flash the OTA. You CANNOT S-OFF every unless they break the 1.54 HBOOT (or you pay a shop to do it for you)

ROMs don't touch your Hboot, that is why you can run 4.3 based ROMs on 4.2.2 ... Only an OTA or manually fastbooting the firmware would change your Hboot. Checking your bootloader will tell you this. Mine is what it says in my signature, yet I'm running a 4.3 based ROM.

... unlock bootloader, custom recovery, root, s-off, downgrade to 4.1.2 and then you can sim unlock :victory: ...

if i've done the sim unlock through sprint international, and then switched ROMs afterward, will i still be sim unlocked?

Hey guys. I was trying to install a ROM, but when I installed TWRP I was put into a bootloop. Now, I have managed to get myself into a bad pickle. I have S-On and my bootloader is relocked. I cannot get fastboot oem unlock to work so I'm pretty limited. I need large amounts of help now. Thanks guys.

As long as TWRP still works your not totally screwed, flash a rom and get s-off again and use the GURU bootloader tool to unlock, don't try and flash a RUU or firmware with stock recovery that will really be the end

do you have adb and fastboot installed on your computer? open a command prompt from adb folder and type "fastboot getvar all" post the results here except the IMEI and the serialno

There write only "waiting for device" and nothing happened. I need to do something more or?

is your phone booted in bootloader mode with htc drivers installed?
btw s-off will be a long journey if you don't know how to use adb and fastboot. Better to learn the bascis first before attempting to s-off. Otherwise, you'll probably end with a bricked phone. S-off is for advanced users and should only be attempted if you know what you are doing.
What is your goal, why do you need s-off?

Here it go:
HBOOT 1.57
baseband 4T.29.3018.08
Something more?
I want to set ViperOne ROM

s-off can't be achieved with revone on hboot 1.57 like said in revone thread, only for 1.44. with hboot 1.57 you must use firewater or sunshine s-off. You don't need s-off to flash a rom like Viper.
unlock the bootloader, flash a custom recovery and then flash the rom (viper)

The ViperOne Thread does say "S-Off Recomended", however, not required. With your current firmware you are able to flash ViperOne 7.0.1... If you had a previous firmware and unable to s-off to update, running ViperOne 6.2 is an option as well.
