[Q] Downgrade Hboot 1.54 to 1.44?

Ok so i have searched but unable to find an answer to my question.
I want to downgrade my Hboot from 1.54 back to 1.44. I do have s-off. I s-offed when my hboot was on 1.44 using revone. My hboot was upgraded after doing a firmware update.
So i need to send my phone in for repairs (the infamous purple camera) and i want to downgrade so I can return to stock, remove "tampered" and relock.
As stated I am currently S-off and have read its possible to downgrade if you are s-off, just need to be pointed in the right direction

I wouldn't downgrade and s-on for warranty, it isn't necessary, they won't check and you will regret it because you will get back your phone s-on and upgraded to hboot 1.54, so non-s-offable for now. I did it too without any problems.
Just make you phone stock again (install a stock ruu is it is available), lock (not relock) your phone and remove tampered flag (running an ruu would remove it, if there is no ruu do it first because revone won't work without root on hboot 1.54)
BTW purple camera is just software whitebalance problem not a hardware problem

You just need to downgradethe firmware. It contains the hboot.
But as @godutch said, it's not necessary.

Ok cool, thanks guys, so I just need a flash a firmware zip containing 1.44 Hboot and im good to go?
Basically i just want to get rid of the tampered flag.
Iv done the 4.3 upgrades with supposedly fix the camera but its made no effect on mine :crying: so the only other option I have to try and get them to change the camera module.
Thanks again guys. Much appreciated. You will get a thanks each

you don't need to downgrade. h-boot 1.54 is normal and considerated STOCK for devices who made OTA update.
don't do stupid thing's
i removed tampared flag with revone -t

it does but you need to be s-off and rooted for it to work but you don't have to do what you are trying to do and you will regret it later....

just try with 1.54 , multiple times

hboot 1.55

I had my phone repaired twice and they didn't say any thing about the boot loader being unlock. However, since that I have s-off and the phone needs to go to repair for the microphone not working and I wonder if I could either s-on and lock the boot loader with hboot 1.55? If you have any advice, I would appreciate it. Thanks.

not recommended, as far as i've seen, going from s-off to s-on (on 100% stock everything), after a few reboots, has a high chance of resulting in "tamper detected - rebooting" and the TAMPERED sign is back.

[Q] Going back to s on

Hoping you guys can help me
I s offed my phone using rumrunner, downgraded my hboot to 1.44 and restored my 1.29.206.7 O2 stock nandroid backup. I ran revone, locked the bootloader, removed tampered and updated to the latest 3.62.206.1 firmware. I need to send the phone back for repair so I did fastboot oem writesecureflag 3. I rebooted the phone and on first reboot the phone boot to the lock screen, froze and then reboot. This kept happening until a factory reset, after which the bootloader read as tampered and locked
My bootloader was 1.55 and not a modified hboot as I had come from hboot 1.44, although I don't think this hboot was for my model id or cid (I changed the android.info file to flash it)
How do I safely go to s-on for repairs? Or should I leave it as s off and locked bootloader. I'm sending it to o2 rather than HTC

Unlocking 'relocked' bootloader with hboot 1.55 and S-OFF

Well, I'm usually able to dig myself out of messes I get myself into but this one has had me hunting a few hours. Here's the run-down.
1) S-OFF with 1.44 a while ago, rooted and unlocked bootloader
2) Got camera problem, would like to return phone to stock for warranty
3) Flashed a stock RUU, went fine. Stock recovery and bootloader work fine, hboot was upgraded to 1.55 (my mistake, should have noticed this)
4) Got sidetracked when trying to lock the bootloader and entered fastboot oem lock
So now I have a 're-locked' bootloader on 1.55 with S-OFF. I don't want to unlock through HTCDev, I can't use revone to unlock because I'm on 1.55, and I don't have a custom recovery, and can't flash one because I'm relocked.
Any ideas how I can unlock the bootloader here (or downgrade hboot, I have the zip but can't flash it)? I can probably handle the rest myself, after I smack myself over the head a few times.
The goal here is to have the bootloader 'LOCKED', and I'll then take my chances with S-ON, with the latest firmware but a downgraded (1.44) bootloader before handing it over for warranty purposes.

OK, it looks as though I can patch hboot files OK. Will take a look around for a patched one.

Hboot 1.44 will unlock using revone. Make sure to be on 1.x.x based ROM right after

Sorted, thanks. Found an older ROM that flashed fine with supercid. Think I'll keep S-OFF and just lock the bootloader. With this being a likely hardware issue I'm hoping I'll be fine with just that.

Soft Brick or Hard Brick?

Hi guys,
I had back to completely stock my m7 for guarantee 2 weeks ago. Yesterday i tried every possible way to s-off but i can't get it. So i tried run RUU for downgrade OS,hboot etc. relock bootloader. But accidentally RUU removed OS; no main version in getvar, stock recovery, relocked and there is a warning under relocked title it says ''security warning''
Run RUU or flash update.zip,rom.zip,ruu.zip no matter what,I get 'failed: remote signiture verify fail'. Phone does not boot, because no OS, so no adb. Is only way J-tag for ressurrect it

you can not downgrade with s-on!
re-unlock your bootloader, flash a custom recovery and a rom and achieve s-off with sunshine then follow nkk71's guide to return stock (linked in my sig)

I can't unlock bootloader back, flashing unlock_code.bin and allow prompt from phone, it goes to update screen, 2 minutes later i get red triangle screen. I have to unlock my bootloader without unlock_code but my hboot 1.57. So i think my device is dead

Try generating another unlock bin

[Q] Can't S-OFF, tried everything!

Hey guys,
I know there are threads everywhere like this, but all I want to do is take my M7 back to stock and sell it. I've tried everything I've seen and I'm frustrated. I have root with SuperSU and TWRP recovery. I had S-OFF with an unlocked bootloader and stock Lollipop, then used revone to set the lock flag and set S-ON and remove tampered. Then I hit factory reset in bootloader, which was a huge mistake because now it's S-ON and tampered.
Since then I've tried revone, and setting the -P flag does not work, and running ./revone -s 0 -u on my mac doesn't work either. I'm running revone with su. I've also tried rumrunner in Windows on VMWare, which never gets past the sanitizing stage (even though SuperUser is granting permission to 'id'), and it just displays TTTTT**************** and press Enter to Exit.
I've also tried both locked and unlocked, and I had a newer hboot before and it didn't work either.
Here's my bootloader:
*** TAMPERED ***
*** UNLOCKED ***
M7_WLS PVT SHIP S-ON RH
HBOOT-1.60.0000
RADIO-1.01.20.1225
OpenDSP-v35.120.274.0718
OS-6.16.651.2
eMC-boot 2048MB
Jan 9 2015,22:07:44.0
I'm out of ideas and I just want the quickest way to be done with this phone and sell it.
Thanks in advance!

Lock the bootloader and flash the 7.x RUU and forget about it
Only HTC cares about the phone saying Tampered / Relocked no one else cares

Ok I guess. Was hoping there's a simple way to do it because the phone just sold and I hadn't posted that it has a tampered flag. Is this the RUU I should use? http://forum.xda-developers.com/showthread.php?t=2658910. I need a decryped version I can install with Mac because I'm not having luck with the Windows RUUs in VMWare.

Sunshine s off is your only chance with hboot 1.60

How can I upgrade hboot to have more options? Also, is that that the right RUU to use? Lastly, trying to relock bootloader with revone and that's not working now.
Thanks for the help!

Sunshine is the only option for hboot 1.57 and up. Upgrading hboot won't give you more options. Revone is only to be used with hboot 1.44. If you want to relock then use fastboot oem lock. And no this is not the right ruu. It must be same version or higher when s-on.
