How to Downgrade JB 4.1.2 to ICS 4.0.4 - HTC One SV

Htc One SV How to Downgrade JB 4.1.2 to ICS 4.0.4?
Please and thanks!

I never did, but in short (i think this way should work):
Get S-Off, extract hboot 1.00 from ICS Ruu (with Linux), flash 1.00 hboot to your phone and i think then you should be able to flash the whole ICS Ruu.

[Q] Stock Hboot

I'm trying to get back to stock hboot on my sensation so I can send it in for warranty. I tried running the stock 1.45 ruu and it didn't change. I tried running the 1.29 ruu and then running the OTA update and that didn't work either. Can someone just provide the stock hboot so I can flash that please?
-The method I used to unlock was unlocking through htc and then rooting through revolutionary.io

How to upgrade to ics with hboot 1.23 s-on?

Two month ago, i did some stupid things and then hboot turned into s-on. Because hboot version is 1.23 which is not supported by revolutionary, i can't upgrade, degrade or s-off the bootloader.So i can't flash any ics rom. I tried to flash ruu. No matter what version of ruu is, it always shows error 155 or else(i tried to relock the bootloader, other error uccured). Now official ics has been released, will latest ics ruu help? my device is asia sea wwe.

Re-engineered HBOOT 2.00.002 and ICS.

Hi, guys, first of all I'm an absolute noob so bear with me if I didn't found all the answer even after having searched through the forum.
My big question is about the re-engineered HBOOT 2.00.002. I have a virginal Desire S, non s-off'ed and non rooted, HBOOT is the latest, that is 2.00.002. I want to load the latest official ICS rom from htc and, as I think I understood, HBOOT must be latest version, therefore non s-off since there is no way to s-off that version. But I also would like to just go to CM10 in the future.
Then I read about the re-engineered HBOOT 2.00.002. This HBOOT should give me s-off and the ability to load the ruu rom. Only catch is that you should re-partition the phone. And that's when things get weird. Does I need to do the re-partitioning before installing the ruu ICS rom after installing the re-engineered HBOOT? If so, in order to install the ruu ICS rom, does I need to have any working rom on the phone, that is, does I need to do the nandroid backup to have back my ginger bread 2.3.5 before installing the ruu ics rom?
And going on, currently there is any way to root the phone while on ICS htc stock rom?
But most important of all, what this re-enginnered hboot really is? The revoked/revolutionary mod only works on hboot versions before the 2.xxxx. Is this re-engineered hboot a 2.00.002 official hboot that has been modified to be s-off or is it a previous hboot s-off'ed via revolution but with a different version number?
Thank you all,
Vincent.

If I was you I would forget about the re-engineered HBOOT and just run the RUU and put ICS on your phone.
The re-engineered HBOOT is only for people who have S-Offed using the revolutionary method and have had trouble with the Android 4.0 Sense ROMs. You have absolutely no need to use it now.
If you want CM10 in the future then all you need to do is unlock your bootloader with htcdev, flash a new recovery (4EXT or CWM) and install CM10 from your custom recovery. You will be required to flash the boot.img file separately if you are S-On.
Hi Kavrocks, thank for your prompt answer. I'll surely follow your advice, it's the easiest way and my first goal is to get an easy ICS on my phone. My only doubt is about being able to get to cm10 or whatever else since no rooting hack has already been developed for the new ICS rom.
Do you think HTC will push updates on the new ICS rom or, being it for developer only, it will be just stuck to its original state?

Original.
By what I understand, now that an official ICS ROM is out and thus binary drivers are available, we should expect a fully working non-original ROM in a short time. How much time do you think it will take for the CMx developer to integrate the binaries into the CMx ROM?

Don't tell this my Desire S, HBOOT 2.00.002, S-ON, unlocked with stock ICS and root
Just do this:
- unlock your phone: www.htcdev.com
- Install stock ICS
- install a custom recovery using fastboot
- install superuser using custom recovery
Ok, I've succesfully got ICS on my Desire, eventhough I had to do a 'fastboot oem lock' to get past a 155 error. Now, would you please be so kind to tell me the exact filename of the superuser exploit that you have applied on ICS? I'm asking this to you because I've tried the 3.1.3 on GB2.3.5 and it always hang on 'waiting root access right'.
Thank you.
Vincenzo.

Ok, I'll answer to myself, use the CWM-SuperSU-v0.95.zip archive. It works with ICS.

[Q] Cannot RUU running 1.73 with hboot 2.14

How can this be possible? I'm running 1.73 but my hboot says 2.14. I tried using the 3.18 RUU to update to Jelly Bean but got an image error (158) then I tried to run the 2.20 RUU but I get a bootloader error (140). I understand hboot 2.14 is from 3.18 but I'm running 1.73, how can It be? Is there anything I can do to update my phone to Jelly Bean? Please help. Thank you.
