Hy, it´s possible downgrade hboot from 1.54 on 1.44 or older with flashing stock RUU - RUU_M7_UL_JB_50_HTC_Europe_1.28.401.7_Radio_4A.13.3231.27_10.31.1131.05_release_310878_signed.exe. My HTC One is on 1.54 hboot unlocked rooted but S-on and it´s my problem because I need flashing some things that needs S-off.
Not possible if s-on with hboot 1.54. To downgrade you need to be s-off! If you try running the RUU in your phones present state, the RUU will fail to install, due to the hboot being a higher version presently to the one you are trying to install.
Hope that makes sense?

Short answer: nope. Basically what spikeydoo2006 said. Once you're on hboot v1.54, you can never go back.

You can`t downgrade the Hboot unless you are S-Off.
It is S-ON but bootloader is unlocked using www.htvdev.com
Shall i still S-Off ?

If you have the 1.54 HBOOT already, then the consensus is that you can't S-OFF. 1.54 most likely blocked the current methods of getting S-OFF.
Even if you RUU back to 1.29.401.16, the HBOOT wouldn't change. It's a one way deal if you didn't S-OFF on 1.44 HBOOT.

then how can I make use of my phone again
how can i flash a .zip ROM if my phone is not mounting the sdcard
I'm in the UK & have a sim free HTC One.
So I changed my CID to HTC__Y13 to enable me to get the 4.2.2 OTA early then changed it back to HTC__001 & sadly used Revone to S-ON again. I have no English (United Kingdom) setting in the system language, probably because the update wasn't meant for a uk phone, so my thought was to go back to the 1.28.401.7 RUU then update properly now the UK OTA is out. Obviously I can't do this because I have a 1.54 hboot & can't S-OFF again to flash the RUU.
What method can I use to be able to downgrade the hboot to 1.44, S-OFF & flash the 1.28 RUU? Can I unlock bootloader via HTCDev, flash a custom rom with a 1.44 hboot then go back to stock, lock bootloader, S-OFF then flash to RUU? I don't want to try this & wipe my phone if it won't work.
Anyone else figured a way to do it?
Cheers
Tim
From my understanding, there is no way of altering H-boot without S-off. I'm sure someone will cracking 1.55 in the future.

This is correct.
The update WAS for your phone, if a phone is x.xx.401.x in the UK and x.xx.401.x in the Netherlands they get the same OTA
Can you still change your CID? I read someone who lost S-Off but was still able to change to superCID (11111111)

If you aren't afraid to experiment.
That is simple for information, when my phone had leaked 2.17.401.1 ROM from here http://forum.xda-developers.com/showthread.php?t=2224752
and
firmware from 2.17.401.1 RUU
from here (second post)
http://forum.xda-developers.com/showthread.php?t=2182823
My phone had HBOOT 1.54 and I without problems received S-OFF using alternate revone binary v0.2.1-wlj.
So , you can try this way
1) Unlock booloader
2) Flash latest custom recovery (I had TWRP)
3) Make nandroid backup your system
4) Flash 2.17.401.1 ROM
5) Try to get S-OFF using revone v0.2.1-wlj
I DO NOT guarantee success! If you do it, it is your risk!
I recently switched my one over to GPE and now i want to revert to stock. I am running s-off and hboot 1.54. When I try to run the stock ruu exe for my phone i get an error 158, saying something to the effect that it is the wrong ruu. I know its the right one because ive used it before. Could my hboot version be the problem? If so would flashing 1.44 hboot fix this? Im using supercid 11111111.
As my instructions said, you have to put the 1.44 hboot back first.

I got into a bit of a mess myself trying to do the same thing but got it back in the end.
You need to change your mid back to your original one and, in my case, I had to flash a stock sense firmware http://forum.xda-developers.com/showthread.php?t=2182823 before I could run a sense RUU.
I figured it out. I had to flash 1.44 bootloader and when I did, the stock ruu went perfect. Thanks for the input though. Everyone on here has been a huge help.

Hello everyone,
my phone statement is;
1.54 hboot, S-ON, HTC Unlocked, 2.24.401.x FW.
I just found local service in my city for s-off on 1.54 hboot via javacard. I will use that service. And i have questions:
after getting s-off on 1.54;
- How can i downgrade hboot to 1.44? RUU is enough for this?
- Is there a any other method?
- Is Nandroid backups contain hboot part?
- Can i write super CID on 1.54 S-OFF?
- Can i delete "Tempered" flag when i gain s-off on hboot 1.54?
Thank you,

- Is there a any other method? (You can flash a 1.44 hboot manually without any RUU)
- Is Nandroid backups contain hboot part? (No)
- Can i write super CID on 1.54 S-OFF? (Yes)
- Can i delete "Tempered" flag when i gain s-off on hboot 1.54? (Yes with revone if it works)

Well to start off at the moment you can't s-off on hboot 1.54 at the moment that is after it is available till would be able to flash any hboot so you would be able to go completely stock

So you're going to pay for S-Off and then intentionally get rid of S-Off, and then upgrade, preventing you from gaining S-Off without paying again?
You know, it's probably best to leave it S-Off.
The OTA doesn't remove S-OFF, I went from 1.44 to 1.54 with no issues

Once the OP pays the shop to S-OFF the phone on 1.54 using the java card method he can use any RUU to go back

I am currently having problems trying to s-off a HTC one m7 from three Ireland. It has hboot 1.57 but I cannot figure out how to downgrade hboot. Firewater gets deleted if I try to run it.
Any ideas?

That's the latest hboot from HTC as of now there is no s-off method that we know off... Keep checking on S-OFF procedures hopefully they would be updated to support this new hboot until then you out of luck.
You will just have to wait and hope . You can't downgrade without being s off
