[WARNING] Do not flash a new official RUU/ROM/OTA if you have root and/or S-OFF

DO NOT FLASH A NEW RUU OR OFFICIAL ROM IMAGE UNLESS YOU *REALLY* KNOW WHAT YOU ARE DOING !
Sorry for shouting, but this is very important. Thanks to the mods for making this sticky.
The latest official RUU that has been released - http://forum.xda-developers.com/showthread.php?t=870369 - has been found to break the existing methods of rooting and getting full S-OFF.
This shouldn't be a big suprise, because when HTC saw that the amazing devs on XDA had cracked the existing security, we should expect them to put something even tougher in later releases.
So flashing any later release, whether that's an official RUU or just the ROM image (PC10IMG.zip) is a very dangerous thing to do until it has been fully tested and "cleared" by the devs here. i.e. your previously rooted and S-OFF'd phone might lose root and go back to S-ON, and be unable to be rooted and S-OFF'd again.
It's of course fine if your phone came with a particular ROM release to flash that *exact same* release back onto the phone if you want to return to stock. What I'm referring to is flashing a brand new release that isn't the one that came with your phone.
It's fine to flash custom ROMs of course, because those have already been tested out. In general, it's probably best to steer very clear of new official releases, and wait till the devs have pulled them apart and put any cool new stuff into a custom ROM. Then you know it'll be safe to flash.
Currently I don't think it's entirely clear what just flashing a new *radio* on its own will do, as opposed to the entire ROM/RUU. That's still being worked on. But steer clear of even that if you're not sure what you're doing or dont' want to take any chances of losing root/S-OFF.
Thanks for reading

Thanks for the heads up.

I flashed the ROM you mentioned.
For those who want to try:
Just remember to get REAL S-OFF using gfree before flashing it.
This provide you a medicine for regret. You can get back to WWE ROM using WWE RUU and root/recover your old ROM.

What is RUU? What is it to do with ROMs? Did HTC provide a change log for newer Radio? Or does anyone know what changes are , in the latest Radio?
Just to be clear. Don’t flame me for this please. I’m still learning just like many others in here.

We don't have a changelog, no.
RUU is ROM Update Utility. It's a program to run on Windows (.exe) which flashes your new ROM for you, and holds your hand through the process. It's possible to extract just the ROM zip file from the exe so you can flash it yourself if you want.
The thing about the RUU and stock ROMs is that they will flash pretty much *everything* on your phone. So as well as a new system partition (the main stuff for Android), you'll probably get a new hboot, new radio, new recovery. Those *might* all have increased security which is a lot more difficult to crack. So generally you should not flash it until we know it's "safe" to do so, i.e. it can be re-rooted and S-OFF'd etc.

Ok, thanks for clearing it up. So, RUU is pretty much similar to the method RIM uses to flash its OS on the Blackberries.

Im a little confused here.. So just to clear some things up i hope someone will answer these questions i have.
I have the software on my Desire Z that it came with (1.34.405.5), which i've rooted, S-off'ed and installed another kernel for OC porpuses. This is working fine, but lets say that i wanted to try another rom .. After some time i decide to go back to the stock software and then update to the newest software, would that be a problem? And has HTC released some newer software than the one iam using?

If you flashed back to stock, that would be fine. But if you flashed a new official update (e.g OTA), then you run the risk of installing something that you can't root/S-OFF.
It is best to steer clear of any official upgrades until they've been checked by the devs here and been given the all-clear.
Given that the phone came with certain areas write-protected, and the devs managed to crack that, we should be expecting HTC to release an even more secure update.
Yes, there is a new ROM out, at the moment for Egypt, that seems to have increased security. It would not be a suprise if HTC rolled out similar security as an OTA update for all existing ROMs. Right now there is something in that Egypt ROM (probably the hboot, at the minimum) which mean existing permanent root and S-OFF methods fail. It may be this is easily cracked again, or maybe it will take some time, who knows.
Bottom line - don't apply any official updates to your phone if it is rooted/S-OFF or you plan to root/S-OFF.

The trouble is, HTC/T-Mobile don't want you to root and/or S-OFF your phone, because it's a lot easier to end up bricking the phone if you don't know what you're doing. They put greatly increased security on the G2/DZ/DHD when they came out, in order to help prevent this.
Now this security has been cracked, we can expect HTC/T-Mobile to try and increase security even further (e.g. closing loopholes that let our current methods of root/S-OFF work) in future updates.
So if you accept any future OTA, you run a high risk of accepting something that will lock you out of root and S-OFF, at least temporarily, and possibly permanently (depending on how good a solution they come up with).
If you are not bothered about root/S-OFF, then that's fine of course.
This doesn't mean that you necessarily have to switch to a custom ROM to get updates though. If you stay with the stock ROM (and I'm still on a stock ROM too right now), then just do not accept the update when an OTA comes out, and keep checking these forums to see when the devs say that they can root/S-OFF with the new version. When they say it's ok then you know you can apply the update and still get root/S-OFF.
This already happened with the G2. Very soon after release, but after rooting had been achieved, there was an OTA. Most people here decided to wait until the OTA had been looked at, and sure enough there was a small adjustment needed to the rooting method. But of course this OTA was before HTC had a chance to respond to the cracking of the security, so as I said, any future updates may well require a lot more time and effort from the devs to investigate and crack again.

Ok. Thank you very much

Will this muff up my phone if I factory reset it by using the Power+Volume Down option?

Ok,there is a new gfree method to get root and S-Off.
And gfree can now also be used to set radio S-ON.
But what about the backup "part7backup-1291675121.bin"
which gfree created at my sdcard?
No longer needed?
And with the new root and S-Off method,is it now possible to
to flash stock RUU 1.34.405.5 to get all original?
Because with old UBERROOT method this doesn`t work!

If you do a factory reset then I think you'll lose root, but you can get it back again easily enough. The issue for this thread is flashing new updated stuff from HTC etc.

You might still need that backup, e.g. if you don't know what your old CID was and you want to un-do that bit too. I would keep it.
Sorry I don't think I understand your last question though, or why you say the uberroot method (I'm personally not keen on that name, it's just the usual method using Visionary/rage with gfree, not a new method) doesn't work.

Ok,so I can go back to S-ON with gfree commands from here:
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2
If you are only interested in permanent root you only need radio S-OFF and then it is sufficient to use
# ./gfree -s off
instead of
# ./gfree -f
in the following commands.
And gfree can now also be used to set radio S-ON by using the "-s on" option and to change the CID back to the original value be using i.e. "-c T-MOB010" if you want or have to go back.

But for CID (you mean SuperCid right?) I need the backup?
And with the last question which you don`t understand,I mean
with flashing the HTC RUU 1.34.405.5 I don`t go back to S-ON
and original CID whether I use UBERROT method or this from here:
(Rooting the Vision (G2/DZ) and DHD)

Thanks for the advice, I will stick myself with the current rom for a while

Yes, I mean to go from your SuperCID back to your regular CID. You might not know what your original CID was.

Yes, if you flash a stock ROM then it won't affect your S-OFF and CID status (or SIM unlock). These are stored in your radio configuration partition, and not in any of the partitions which are overwritten by the ROM flash.

[Q] Unrooting for insurance

I have seen some threads about un-rooting for warranty claims, but want a definite answer before doing anything.
My DHD has ENG S-OFF, Radio S-OFF and Clockwork Mod Recovery, and basically I want someone to be able to tell me/ point me in the direction of files and instructions for returning my handset to 1.32 stock with no superuser, custom recovery or s-off's of any kind.
Also, if the engineers where to update my phone like i know their prone to doing, is it still possible to downgrade back to 1.32 and root again to get my beloved MIUI back?

you can download a stock rom from the links on this thread:
http://forum.xda-developers.com/showthread.php?t=846248
And It'll take the HTC back to it's factory defaults, as if it was new. It'll probably be best to use the RUU (that's what it's called) for Orange UK (if your phone's locked to that, assuming you updated your operator)
HOWEVER! Running an OTA update to gingerbread from the new system'll leave you with a probably unrootable Desire HD (to check if it's still got the radio S-off at least, go into fastboot and check that the CID is just 1's)

So I would install this like a ROM through Clockwork Mod?
So would this RUU remove all of my custom recovery, and S-OFF's? It's just I wanna make sure it's all gone just in case....
So there is no way that these can be downgraded like 1.72 can be?

Narh, you don't flash it through clockwork mod, it's run from your computer. You'll need the HTC Sync application installed on your computer, and a sense rom to connect the phone via htc sync.
When you run the RUU, it'll tell you what to do. I think it removes a ENG S-OFF but but a radio S-OFF'll stay on the phone (it is more or less permanent). However, I don't think the radio s-off'll show up in fastboot that obviously.
The reason you can't downgrade the firmware on RUUs is because in the process of rooting, the phone's CID changes to 111111111 (or something) so the PD98IMG file for downgrading will refuse to work with the phone because of an "Incorrect CID"

Unroot US Cellular Desire

I have done a search and found a few helpful tips but nothing straightforward. I know there isn't a RUU for it. Long story short. My boss downloaded the official 2.2 update, it broke his wifi. He asked me to root it to see if a custom rom would fix it. I did and installed CM7 but wifi still doesn't work. Now he wants me to unroot it so he can get a replacement because he thinks it is a hardware problem. Anyway, I am going to attempt to flash the official 2.2 update to his phone which I am assuming unroots it. But, the phone will still be s-off, does anyone know how to flash an s-on hboot? If the wifi works when i reflash the 2.2 update I won't need to worry about the hboot but I hope there is a way. Thanks

Well looks like a found the 2.2 RUU. Will this unroot aswell as flash the stock hboot?

Yes, if you run a RUU, it will return everything to stock. But if you installed the CM7 with the newer partition layout (Bravo CM7 r2), then you should downgrade it first, and then run the RUU.
Edit: http://forum.xda-developers.com/showthread.php?t=1016084 Watch this video here, it shows the process.

Downgrade the ROM?

No, downgrade the hboot. Enter into bootloader and check your hboot type: if it's CM7 r2 or Oxygen r2, then you need to downgrade them first before running a RUU. You can use the Bravo Downgrader on the Alpharev site.

Thank you for your help. One more question tough, on Alpharev's, it says that the Desire downgrader is for the GSM models but it makes no mention of the CDMA models, do yo know if it will still work?

Hm.. Now that's a very good question.. I don't have answer for that, sorry.

unrooting the DHD

Having spent time looking on here, I cannot seem to find the info I need... I rooted pre-AAHK (by downgrading and using visionary), so am not sure if I would be able to use the Hack Kit to un-root my phone
I realise that running the correct RUU is likely to be the way to go... what about S-Off? As far as I have read, running the RUU does not put your phone back to S-On.
Would someone mind letting me know if this is the correct order to do things:
Downgrade to 1.32 (by running the 1.32 WWE ruu) - Would it be possible to run 1.32 WWE ruu regardless of what my CID currently is? Also, would this give me WWE/unbranded CID?
Temp root with visionary.
Use the S-Off tool to get to S-On. If wanting to return to carrier branded, then you would also be able to change the CID to whichever Carrier ID wanted.
Install RUU of choice, be that branded or non-branded.
I think that's it... if someone could confirm if I've got this right or let me know if I've gone for overkill?
Cheers all!

Help DZ noob to flash KitKat onto it

Right now I have stock 2.42.405.3 and available update (6,55Mb so probably .4) and HBOOT-0.85.0013 with S-OFF (so previous user probably was playing with this device).
What I should do now?

So it seems that for fastboot I need this Engineering HBoot or after S-OFF I have full access?
Coz all guides for Eng HBoot are for downgraded devices and all the guides for downgrading are for S-ON devices...
However I've also found that Eng HBoot was used when S-OFF was not possible and now it's not recommended, what can mean that S-OFF gives access to Fastboot same way the Eng HBoot?
If ti is true, than flashing Recovery will be easy and than I can check Roms

Correct, you have what we call fake s-off and only gives you a bit of help flashing your phone, to get true s-off the preferred method is to go back to stock and then downgrade and root with gfree
Relatively easy but a few steps needed first
If you have a chance to go to g2root on freenode iirc there is a good likelihood that guhl is there and will walk you through it all
