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)
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2
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 everyone!
This is the situation:
I got my unlocked HTC Desire HD from an authorized store but when I started it (at home) I've noticed that is branded from T-mobile Germany.
Since I use a Vodafone SIM, I decided to unbranded it. So I installed this stock ROM: RUU_Ace_HTC_WWE_1.32.405.6_Radio_12.28b.60.140e_26 .03.02.26_M_release_155891_signed. I followed the steps described in a thread on this forum, using Visionary and One click S-OFF tool. Everything was just fine. My device works without any problem except one: can't find OTA updates.
WHAT COULD IT BE? IS THERE SOMETHING I COULD MAKE TO RESOLVE THIS ISSUE?
Thank you in advance,
joaquin
As far as I know, once you have s-off and root and a custom Rom installed, the ota update will not work. If you want the update you will need to install a custom Rom running the new update.
Sent from my Desire HD using Tapatalk
I understood that the stock ROM is not a customized ROM.
And I checked in bootloader and the first row looks like this:
ACE PVT SHIP S-ON
Doesn't this mean that my device has S-ON?
Is it possible that my device to be still rooted? If yes, is there a solution to make it unrooted?
Joquin
To be more specific, when i say can't find OTA updates, I mean I don't receive notification about updates and when I manually check it says "There are no updates available for your phone."
Do you know which CID you have on phone?
I had rooted, Eng S-Off and Radio S-Off (Super CID-11111111) on phone and phone found OTA update. Although I didn't tried to install it since in that way I'll be loosing root.
If I understand correctly youre still on 1.32 and you want to aquire root and S-OFF AND you want to update to 1.72?
If that is what you want, you will not be needing a prompt from your phone to update the system, because that way you will not be keeping root/S-OFF after the update.
Ensure you have BOTH Eng S-OFF and Radio S-OFF and you did temproot with visionary+. Check IVO's refference thread for that.
Its gotta work.
Then, for updating the phone correctly, take your time to read this:
http://forum.xda-developers.com/showthread.php?t=885996
its not an easy guide for beginners (such as myself), but if you read the entire thread you will eventually get out. I did too.
I'm sorry, but I don't know where to find the CID number.
In the bootloader doesn't appear.
Joaquin
@maurei
I know if I will update to 1.72 is not possible to root at this moment and probably I will not make this update. But I want the OTA updates working not only for now.
Thank you anyaway
Joaquin
ah, hit quick reply instead of edit I guess.. soz for the dubble post, del this one
Thats what I'm saying my friend - you CAN have root AND 1.72
Its not possible to root fromin 1.72, but it IS possible to maintain root as you upgrade from 1.32 to 1.72 .
Reading my previous post made me realize it wasn't so clear.

I meant:
Then, for updating (=manually installing the update through recoverymode) the phone correctly (correctly =MAINTAINING ROOT and S-OFF), follow that guide.
Be sure you have ENG S-OFF and Radio S-OFF + permroot with Visionary+.
Also, be sure not to remove any preinstalled apps as this will cause unnecessary problems during the install
Sorry if I wasn't able to make myself clear.
My goal is not to have a rooted device. Maybe in the future I'll make this step if it will be necesary.
I want my device as new one, from store. I explained in the first post of this thread why I'm in this situation.
Through this thread I want to find a way to get OTA updates.
BTW, I understood that if the device is rooted OTA updates aren't possible. So I installed visionary+ and I used the "unroot now" button and I received this message: "your device doesn't appear to be rooted" or something like this.
It seems is not about unroot or s-on (see the 3rd post, too).
Anyway, if somebody has any idea, it would be apreciated to share.
Thanks,
Joaquin
You should at least get radio s-off before you upgrade. You'll thank me later if you decide you do actually want root.

Hey folks. I'm looking into updating to the latest radio, and so I've concluded it's finally time to get the engineering bootloader onto my phone. I have enough experience with my old G1 to not be super-nervous about it, but I have one quick question first.
When originally rooting using gfree back in late December, I decided to skip the SuperCID and SIM-unlock portions of the process. The wiki instructions for the eng-hboot, however, assume the user did all three options. With simply radio s-off, can I install the new bootloader, or do I need to go back and get SuperCID first?
Thanks for any help you can give.
You dont need an ENG Hboot to flash the new radio you can use the PC10IMG update method. Heres a link to the post with the download.
Thanks, joemm - reading through the various radio topics, I've gathered that you've been really helpful in providing PC10IMG files for people, and that's really appreciated.
My concern is if it turns out the new radio is worse than the old; it seems like the easiest way to go back to my current radio is through fastboot flashing, which is why I wanted to go to the eng hboot. I don't see a pc10img already out there with my current tmo, post-OTA radio (though it's listed in the mega-radio topic).
So, I guess my quesion is still open - do I need supercid to flash eng-hboot?
Actually I have a similar situation. I also skipped SuperCID and SIM-unlock when using gfree. (Not sure why I did, but Im sure it made sense at the time)
Anyway I have the eng hboot but would like to upgrade the radio.
Can I run gfree again to do the sim unlock and then upgrade the radio? Or upgrade to this radio - Vision_RADIO_12.28h.60.140f_26.06.02.27_M - and then run gfree again?
What does the sim-unlock change and supercid change acually happen anyway? I mean does it make a change to the radio itself?
Sim unlock makes a permission state change. Makes a 1 a 0, as I recall. Dunno bout SuperCID.
HTC Vision 1.8 OC, CM7 RC1==HAPPY!!
Thanks for the reply Daughain.
But where is that change made? is it made to the radio itself?

I don't think it changes the radio, because I've personally switched radios several times and I didn't have to unlock every time. Once, when I rooted the phone and that was it.
I managed to root and install cm7rc1 with the newest radio and when i went back into fastboot, I noticed that S-ON was activated again. did a search and discovered that crazy HTC sets security and somehow i undid my S-OFF. I was going to use the .exploid root method but i can't write to the phone anymore. I think i still have clockworkmod recovery. so am i still rooted? can i even flash an OTA update. any suggestions? thanks.
(update: in my haste i forgot the search, i'll delete this if i find a solution)
To figure out if you still have root you can go into Terminal and type "su" if superuser comes up, you accept and it changes the symbol to a # then you're still root but you may not be S-OFF anymore.
First off if u just rooted it it will still have s on the only way to get soff is wilt the alpharev exploit and only way to lose soff is to reflash the hboot and cm7 does not do that so I think u never had soff unless u did the alpharev
After much reading I think I finally understand. I've been spoiled with the nexus one which obviously doesn't have this problem. This is my wife's phone. I thought that after rooting I would get s-off. Anyway, I guess without s-off I have to always update.zip into clockworkmod recovery to flash a cm rom? I am still unclear how to alpharev. Sounds like I need to burn a utility CD and then the app automatically forces s-off. Will need to read more. Thanks for the replies/help
I have a colleague that is on her 3rd G2 exchange (after my suggestion of her to get it after coming from a BlackBerry) and they have all suffered from the same condition of chronic dropped calls within the first 10 seconds of the call on about 50% of all calls. I've got a Nexus One which never experiences that in the same geographic location (we work in the same office) so I'm pretty sure its not the signal strength in the area that's the cause - we both get full bars on HSPA. I'm thinking as a last resort before she throws in the towel and gets a BB Bold instead to try to update her phone's radio to solve this issue for her.
So, she has absolutely no interest in custom ROMs, rooting, voiding her warranty or anything else that is above the scope of a "normal" phone user. I'd like to try out a new radio version or two on her G2 in the least invasive way possible.
What is the minimum amount of modification needed to be able to flash a radio update?
Radio S-OFF?
Super-CID?
Engineering HBOOT (0.76.2000) ?
Or, is it possible to update the radio without doing any of these?
I'm absolutely confident that I can do any and all of those things but just want to spend as little of my time doing this for her and want it to remain as close to stock as possible for her.
Thanks!
joemm, the OP of the of the [RADIO][ZIP]- HTC VISION RADIO's (PC10IMG.zip Update Files) thread has PM'd me this reply for anyone else wanting to know this information for themselves:
You would have to root her phone and either superCID or ENG. Hboot.
2 ways:
Root + SuperCID - you can use my PC10IMG zip files to flash the radio.
Root + ENG. Hboot- you would use terminal on your comupter to push the radio.img to your phone in fastboot mode. In order to use fastboot you need the ENG. Hboot.
Either way requires root S-Off which voids her warranty, but there are methods to unroot and return to stock S-on in the forum. Also remember there are always risks involved when rooting, so make sure she's aware of them and still wants you to try this for her. Good Luck.
