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!

What do you mean with gfree?
Is my waranty broken When i execute radio s-off?
Is it possible to make it radio s-on?
Yes,warranty is broken,but with the new gfree method
you can go back to S-ON:

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.
Hi I would like to know if there would be a problem if I flash the official rue of an Asian desire z with a european version or vice versa?
I bought my phone second hand and I decided to flash the 1.34.707.1 version into my originally 1.72 desire z. Now my phone cannot find updates. It keeps telling me that there is no update even if check manually.
I know that I can flash a higher version by downloading a higher rue version but what I wanted to find out if I can no longer receive ota updates because of what I did.
Since when I was in 1.72 my phone did not notify me of the 1.82 update too...
I don't know what's wrong.. Please help. Thank you.
I think if you are SuperCID and S-Off, it would work. Otherwise, it won't let you flash the ROM from another region.
Also, if you flash an official ROM, you will lose root, and you can't get it back on any ROM version higher than 1.34. For this reason, if you downgraded to 1.34 for purposes of rooting, you don't want the OTA updates, anyway.
If you're rooted and S-Off, and you want a more updated ROM version, just flash the Virtuous custom ROM. Its mostly stock 1.85, but rooted, and with a few cool added features and some optimizations.
Hi, the thing is I'm not very knowledgeable when it comes to rooting. I read the posts here specifically in the wii section and I don't think I have the skills to pull it off and risk bricking my phone.
I think my phone is not rooted or it was before but not anymore, since as mentioned I flashed an official ruu.
So basically, I should still be able to receive OTA's from HTC right? I was wondering why my phone keeps telling me there's no update when the software number is 1.34 stock and not rooted. Shouldn't it notify me that there's an update at least regardless of whether I want to or not?
If you are not rooted, why did you downgrade to 1.34?
I also don't understand why you want to flash the RUU from a different region. If you aren't SuperCID and S-Off it won't work. Why not just flash the latest official RUU for your phone versions/region if you want to be updated and don't care about root?
I'm not sure why your OTA's don't work. I'm still on 1.34 (well, back to it), and I still get notifications to update.

@redpoint73
I bought the phone from a friend of mine. I noticed that it had eng hboot and had s-off.
I have zero knowledge about rooting. When the gingerbread test rom for the desire z came out, I flashed the pc10img.zip via the bootloader, however since it was very buggy and laggy, I decided to flash stock desire z rom.
Having no knowledge about rooting I read some of the threads in this forum and learned that flashing an official rom i.e. the RUU would be the easiest way to return back to stock.
It worked, I am using stock rom. I experimented and found out that I can flash any of the RUU, so I chose any of the WWE release. I decided to flash an older firmware version specifically, the 1.34.707.1.
Now the problem is my phone doesn't prompt me with an update, even after checking in about phone > check for update.
I still have s-off but eng hboot is gone. To clarify I was not the one who rooted the phone, so I have no idea what to do.
Is it possible that the previous owner tweaked something in the phone that would absolutely prevent it from receiving OTA?
I am just worried since I have a feeling that the gingerbread OTA will be released in a few weeks since the update for the Desire HD is already out.
Please help and thank you again. I extremely as a NOOB!

I wouldn't worry about getting the official Gingerbread ROM OTA. It will probably be posted here or at shipped-roms.com long before you would get it OTA.
Hi All,
I have a US Cellular BravoC that needs to go in for repair. I am one of the unlucky ones who are experiencing the overheating/forced resetting while doing CPU intensive tasks.
I currently have S-OFF, CWM Recovery 3.0.2.4
I know that I can download 2.2 RUU in fastboot and that will return my phone to unrooted, S-ON... and my warranty repair should go through fine. The problem is, I want to be able to return to CM or Oxygen when I get my phone back.
1) If I return a phone with S-OFF and CWM recovery is it likely that HTC will deny the warranty repair?
2) Does anyone know if there is an RUU for 2.1?
3) Is it possible to flash the stock recovery and leave S-OFF as a back door?
4) Is it even likely that I will get the same software back? In other words... should I not even worry about because I will likely get back something different (Just flash the 2.2 RUU and say screw it).
I still do not really understand the whole "goldcard" thing or how to really use fastboot effectively, so I don't have the untouched ROM that came with the phone. Only the rooted one I created with nandroid backup before installing CWM
Sorry, I know that is a lot of questions but they are all very closely related. I have searched through the forum and did not find anything that really answers these.
Thanks for any advice you may have!
When you get your phone back you can just reroot and S-OFF again. You need to find the US Cellular ruu and run it.
Maybe someone else can help you with that.
So if I understand this correctly, even if I have 2.2 installed (which, as of now, can not be rooted) I could find and install the 2.1 RUU and then root the phone? I think the problem is HTC never released a 2.1 RUU. I am pretty sure I go to 2.2 (or HTC upgrades my phone to 2.2) I will lose the ability to root it.
Man, I just hate the stock ROM so much I want to try avoiding it at all costs.
Phone won't load recovery -
My phone currently has 2.3.3 and will not root because the firmware is too "new" according to Unrevoked.
How do I backtrack to 2.2?
Also, the phone is not rooted (s-on) and recovery once again will not load properly; i get the red exclamation.
Any help would be greatly appreciated, thank you.
There are a few threads addressing this issue already, and the short answer from what I have found in my research, because I too took the OTA update and have looked in to this myself, is that there is no option.
If you are S-ON and have the new Bootloader and newest OTA update, you just have to hang tight until the devs behind Unrevoked or other such methods figure out a workaround for the newest bootloader.

Hey man, I am sorry to inform you that there is currently no root method for the software you're on. You can't downgrade to 2.2, the RUU won't let you do it. The new bootloader that you're on is not downgradeable, and it is still currently locked. Hopefully a new exploit is figured out soon, but for now you just need to wait it out. Or trade your Evo with someone who still has froyo!
Thanks for the info guys.
Not sure is any of this could render your phone without functionality and If you are willing to give it a shot, try the first part of my post. After I unrooted the defective EVO to accept the OTA (since it was going back in a day anyway and didn't care if the root was lost) adn it was along with my .76 Hboot. I was able to get root back by using the HBOOT in stock recovery and loading the RUU posted with of course loading the usb drivers. Now, to be honest, I never used unrevoked to begin with on that EVO, so never checked son/soff before.
If for some glorious reason you are able to load the ruu and it comes up...try the root option also posted from the link to xHausx.
Here's hoping....but reality will probably set in and a short wait is needed for a real method.

unfortunately no root for 2.3 but rumor has it that htc is working on unlocking the new bootloader with a update coming in the near future prob 2.3.4
