What does the RUU replace exactly?
Can I brick my phone by flashing the wrong RUU?
Why do people downgrade instead of flashing an older RUU?
The RUU replaces everything. Radio, bootloader, ROM, recovery. So you'll loose root and ENG S-OFF but you'll keep radio S-OFF.
You cant flash an older RUU if you don't have S-OFF.
And no, it doesn't matter which RUU you flash.

is the radio S-OFF flag hidden that deep? even an RUU wont reset it!
so basically if I have radio S-OFF I can flash any RUU I like. that's cool
btw what's ENG again? and what's the different between ENG S-OFF (or ON) and radio S-OFF (or ON)?
my understanding is that if you have radio S-OFF then everything is S-OFF and you can mess with the device as bad as you like
the way i understand, you could say Eng S-OFF is a "security off" placed after bootloader and Radio S-OFF is a "security off" placed before it, so even a normal bootloader see it as a S-OFF... please, someone correct me if i'm wrong.
Radio S-OFF isn't THAT deep, it's just stay in a place not touched by flashing officlal RUU.
So when you are Radio S-OFF and flash a RUU, bootloader and everything beyond it is replaced; you keep with a Radio S-OFF (cause it stays before bootloader), but lose Eng and Root (cause it stays after bootloader).
you can't flash a older RUU without Radio S-OFF and to achieve it, you need eng s-off and for that you need root. So, if you have a 1.7xxxxxx RUU, you can't simple flash a older RUU...
i hope it could be understood, my english is not quite good when i need so much adverbs, past sentences and whatever more! =o)

From my current understanding if I wish to flash individual pieces of a ROM such as a new radio or stock recovery (for warranty purposes) I need the eng hboot for fastboot? And returning to the original hboot is as simple as flashing a stock RUU, after setting superCID and permanent S-Off with gfree of course?
hey,
Today i finally desided to perm root my DHD using this guide http://forum.xda-developers.com/showthread.php?t=928160 everything went fine and it all seems to work, i desided to install rom manager and flashed clockworkmod recovery. (clockwork also works fine and I have made a backup of my stock rom)
now i want to install this rom Android revolution HD http://forum.xda-developers.com/showthread.php?t=984045and i need radio S-OFF and HTC desire HD S-OFF.
when i go into bootloader the top line say's ACE PVT SHIP S-OFF does this mean I am good to go?
and can I go back from android revolution HD to the official rom with nandroid since it is version 2.16.0.0?
thanks in advance

YOU ARE Doing these well, if you flash ARev.HD later you can go back flashing an stok rom take this link for choose your OFFICIAL RUU...
http://xdafil.es/index.php?path=DesireHD/RUU/
but i think that if you taste a cooked rom you are not going back to RUU OFFICIAL ROM hahahah
CERTAINLY.. have you made HBOOT S OFF ENG-SPL????(its fully reversible flashing an stok rom) and It makes possible to recover the system of a bad flash recovery...
sorry for my bad english
What I think SERGI.3210 is trying to say, is that you need ENG HBoot or ENG S-OFF before you can flash radios.
Here are the threads you should read,
ENG S-OFF
RADIO S-OFF
I did not flash (well, I dont think I did) hboot and i don't now how to do this either the tekst in bootloader says this:
ACE PVT SHIP S-OFF
HBOOT-0.85.0007
RADIO-26.03.02.26_M
eMMC-boot
How do I make HBOOT S OFF ENG-SPL and is their a way to check if I already have it?
And what does this do?

uups!!! thanks andyharney! i forgot to put that you need ENG S-OFF to flash radios!!
certainly... take this XDA´S LINK for go back to OFICIAL RUU:
http://xdafil.es/index.php?path=DesireHD/RUU/
Use the ENG S-OFF tool in the first link to get ENG S-OFF. Without this you cannot flash radio.img's via fastboot.
Once you have ENG S-OFF use the other link to get Radio S-OFF. The tools are very easy to use and 99.9999999999999999% safe.
I took another look at the article i used to root and it said this:
you will have permanent root (S-OFF), as well as subsidy unlock and SuperCID. At this point, you can also choose to flash the engineering hboot
If you don't want the engineering hboot, just reboot your phone. You can verify you have permanent root by holding volume down while powering on (you'll see S-OFF in the first line of the bootloader). You are now free to install a new recovery and start flashing custom ROMs. If you don't want to flash a new ROM, it's safe to uninstall the Visionary app at this point.
Does this mean i already have radio S-OFF?
I need to get back to stock hboot for warranty, but can't find a way to flash it without using the touschscreen. All the ways I have found use terminal emulator once booted so I can't use them. Is there a way to flash it from fastboot?
Thanks,
Rory

Doesn't flashing an RUU overwrite HBoot with stock one? I know it will leave radio S-OFF but I'm pretty sure that it overwrites HBoot, I could be completely wrong and please correct me if I am.

Nope, did RUU update and stayed with eng hboot with S off
Running the 1.32.405.6 RUU will restore Ship S-ON.
Running a 1.32.405.6 RUU will revert hboot (ENG to SHIP) to stock, but it will not revert S-OFF to stock S-ON if you have Radio S-OFF.
Hi!
My phone broke and now I want to try to get it fixed with warranty. I'm not sure if warranty still is available if I use root so I want to unroot.
I have read that all I need to do is flash the RUU, but which one? http://forum.xda-developers.com/showthread.php?t=824357
And what will flashing it do? Will it remove CWM and everything else I was using to root? I remember that I flashed radio 2 times, had S-OFF and E-ON.
And then I will simply run System Update? Because it seems that RUU are firmwares that phones are shipped with.
yea, just flash a RUU.
Make sure you install the original RUU for the type of your DHD (i.e. WWE, Voda,T-Mobile...)
and if your phone is S-OFF, make it S-ON - S-OFF / S-ON GUIDE (guide for S-ON is at the end of the 1st post). Go into bootloader and make sure you have S-ON
--your recovery will be restored to original HTC recovery
Oh, but which RUU I need to flash? I remember I needed to do a downgrade and I think it was 1.72.405.3, not the R2, but I'm not sure.
Well, when you had your phone, was it branded?
if so, you need to find a brand-specific RUU.
If not, then WWE RUU is fine.
i would suggest the 1.32 FW (because S-ON requires temproot from Visionary+), then follow the guide to S-ON
What about radio? I have flashed the leaked gingerbread radio, wouldn't they be able to see that I have flashed a newer radio? Or the RUU flashes radio also?
RUU flashes radio too. But after flashing the RUU have a look into the bootloader, the device might still be S-Off. For S-On you need to root again and Use the easy radio tool to make S-On again. Then use the RUU again.
It still was S-OFF, but used Visionary and Easy Radio Tool to get S-ON. A brand new phone
Thanks!
Does it work the RUU to flash even if I come from an ext4 ROM (ARHD 5.1.9)?
Or do I need to format first by cwm 3.0.2.6 so that it is ext3 again?
No one any advice?
My friend, rooted and Eng s-offed his phone in the beginning, but he didn't radio s-off.
Now he is on Runny 1.5, and he wants to radio s-off his phone whit one click s-off.
But it requires "Desire HD with stock kernel (or Apache14's 1.0.7 / 1.1.4 Sense)"
Can someone link me to one of the kernels so i can flash it for him.?

I think that "s-off" is referring to the radio. If you are s-off you can flash radios through the bootloader. Check the development thread. If you're talking about turning eng s-off, it is mostly recomended to leave it alone. From my understanding it is easier to brick your phone with eng s-off, so I wouldn't do it unless you are sure you know what you're doing.
