[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, 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] stock update S-OFF phone

I've used the search but frankly, the vBulletin search still sucks after all these years.
I rooted the phone following this guide. Now my phone says a system update is available.
Since I would like to install it (my phone is still 1.34, I think. The latest version should be 1.72, right?) and installing a stock update onto a S-OFF phone is highly inadvisable (I've read), how do I go about this?
I have Visionary installed but it says the phone does not appear rooted, even though it is (just checked).
I'm sure there have been others with similar questions and I just couldn't find the right thread. If so, please point me in the right direction.
Regards and thank you,

Why did you root your phone? There is no need to update your phone to the latest OTA update if you are wanting to install custom ROMs.

Because I was testing custom mods and wanted to go back to stock?

ahhh, I thought you had just rooted it. I updated the day after I received my new phone. I had problems with bluetooth (music wouldn't resume after ending phone calls) and wound up here on the XDA forums looking for answers. I ended up rooting my phone, installing CM6 and now CM7 and never looked back. There is no bluetooth switching problems using CM builds so I'm happy.

Found this:
http://www.thinkthinkdo.com/trac/project1/wiki/back_to_stock

Thanks, that looks interesting. Now the only question: Do I need my original CID? And if so, how do I find it now that the CID has been changed by gfree?

That link is about a procedure to restore the stock G2 ROM. Since you seem to have a DZ ROM, I'm not sure if you want to flash a G2 ROM (though the other bits might be useful).
The 1.72 OTA update has been rootable for some time now, so you can safely accept the update if you want. But it might be easier just to flash the 1.72 ROM in its entireity (you can get it from the dev forum).
With SuperCID and S-OFF you should have no problems flashing 1.72.

Really? Then I don't quite understand the stickied warning thread that says to never, ever attempt that.
Anyhow, I gave the Virtuous mod another go. Since it has sense and 1.72 I'm thinking of testing this one out a bit more, before I go flashing stock.
Thanks for the replies, though.

[Q] System Software Updates does not work if you have S-Off?

Hi Guys,
I bumped into something earlier and i want to ask about it.
"System Software Updates" does not work if you have S-Off? Meaning you will not have the automatic OTA update should HTC release any software updates like gingerbread anytime soon..
Can anyone explain this to me or atleast clarify? Any feedback is greatly appreciated.
Much Thanks!

As far as i understand (and as long as you do not install any other custom ROM than the DHD stock ROM), the system software updates should work fine. But if you have deleted some apps or changed something to the system then you will not be able to install the updates!
Do not worry so much about this though, guys here on xda will have a better version for you as soon as htc releases any update.

but this is only specific to changing the STOCK ROM to a custom one. i believe updating and stock app like Adobe Reader won't affect your functionality to do Software Updates right?

Yes. As long as you keep all the apps that came with your DHD, you can download and install software updates (does not matter if you are rooted or not).
But if you have done ENG S-OFF and installed engineered version of H-BOOT and then CWM then you have to flash back the original recovery i guess...

Yes you need stock recovery sure ota.

okay..one more clarification and i'm done..forgive me for so many stupid (it may seem) questions..i'm helping a friend who does not understand english..LOL
so if I have Stock HTC ROM 2.2 Perma Rooted + Radio S-OFF + Super-CID + Eng S-OFF and i did not install CWM and never installed any custom roms (followed jkoljo's one click S-Off and Eng S-off Tool) then i should be okay with Software Updates over the air right?
Once again, much thanks!

I'm not happy to see you, that's a Desire HD in my pocket.

Actually I have observed the same behavior after downgrading and setting radio & ENG S-off.
I haven't changed anything else.
I used jkolio's excellent tools and instructions.
Now don't get me wrong. Not one bad word about jkolio. As far as i'm concerned the man is a life saver. Losing updates OTA is annoying, but compared to losing root is a no brainer.
I'm simply reporting an observed behavior.

Thanks for your thoughts It is actually Visionary that causes you to lose OTAs, you can try undoing permroot. My tools do not modify /system in any way.

Hi again.
@ Jkolio: You are quite welcome .
Regarding OTA:
I tried the suggested approach. In a nutshell: Yes, it did the trick. However not without a couple of hitches along the way.
1: Unrooted w/Visionary r14. DHD reboots as expected.
2: Test using screenshot it. Prog. reports root missing. So far so good.
3: Attempting OTA update. (running 1.32.405.3). OTA tool hangs at the checking phase. Just as if root persisted.
Thinking:"No sweat" "will reroot & report result"
4: Temproot (Visionary). A OK.
5: Attempting permroot. Getting "error - Force Closure" msg. about ½ sec. before DHD reboots.
6: During reboot msg. recieved about OTA update!!!
7: Updating to 1.32.405.6
8: Update done. Reboot. Receiving multiple program force closures including rom manager.
9: Uninstalling botched prgs.
10: attempting reinstall via Market. Market also force closes.
11: Hard Reset.
12: Everything now appears to be humming along nicely & am now running 1.32.405.6. but som setup work to be done.
So. Before you try this. backup what you´re not prepared to loose.

[Q] Downgrade from 1.84.666.2

I stupidly updated my Bell Desire Z to 1.84.666.2 the other day. Looking for a way to downgrade to a version that can be rooted.
Found this thread, but it's for a previous update.
http://forum.xda-developers.com/showthread.php?t=905261
Love this phone but I really want to dump Bell's extra software and Sense.
Please, any helpful input is appreciated!

How far through that guide did you get, what error message? I did 1.84 -> 1.34 to get S-OFF & root.

Following the tutorial got me temp root access but was unable to boot the firmware. I suppose I need to make a goldcard but that tutorial has a few broken links. Anyone want to give me a resource that explains what is going on in that tutorial a little more deeply? I remember reading in a previous forum that 1.8 update could be rolled back.
I'm on a Bell DZ too...

You will need a goldcard if you don't already have SuperCID via gfree, and you can't find an earlier ROM/RUU that matches your CID.
Sent from my HTC Vision using XDA Premium App

I'm getting stuck at step 11. I get to the white bootloader screen and without doing anything the phone does and SD check, looks for PC10DIAG.zip, etc, then finds PC10IMG.zip and checks it. Then I get bumped out to the bootloader list of FASTBOOT, RECOVERY, FACTORY RESET, SIMLOCK and IMAGE CRC.
It's unclear what to do from there. The tutorial says I'll get a prompt to update and restart, but I don't.
Also, the tutorial says I'll need a goldcard (which I created) but no where in the tutorial does it say what to do with it...
I got a goldcard using Gold Card Tool. Just do a google search of "easy goldcard".

I've managed to iron out that issue. I had made a mistake when making the goldcard.
Problem now is that when I get to step 11 the phone says "Model ID incorrect!" then "Update Fail!".
Any ideas?

Where are you getting your PC10IMG from?

From the guide I linked earlier. (http://forum.xda-developers.com/showthread.php?t=905261)
I downloaded the full RUU and renamed the extracted rom.zip.

I had goldcard issues (broken links) so I got the rom that matched my current region. I then did the temp root, modded the version info and let the phone try the update. Once I got it all sorted it worked as is said in the guide. I don't know if the goldcard tool worked or not, I think not as I wanted to change the Asian phone to WWE but had to go down to Asian 1.34 then go S-OFF and then go WWE. Maybe an extra step but it worked.

How do I find a rom that matches my current region?
The desire z was purchased from Bell Mobility in Canada and is now being used on Rogers.

This thread may be of help to you: http://forum.xda-developers.com/showthread.php?t=1029821

Thanks for that link! I basically did as the guy said and used the link to the 1.34.666.1 rom you linked in that thread. Only difference was I uploaded it to the SD and the issued the command adb reboot bootloader. This time no errors and the update worked!
So now I guess I just go ahead with a normal root of a 1.34.666.1 DZ?
Weird thing is the guy in that other thread said he got S-Off from doing this update... On my phone it's still S-On.

All you have done is put a rom on the phone that allows S-OFF, I can't see anyway you could get it in a stock rom?!

You should now be able to follow this guide to get S-OFF (as above, I don't see how flashing a stock ROM would do this automatically): http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision

So after downgrading I had S-ON. But I just finished the rest of the rooting process in the guide I linked in my original post and got root!
What a process. That must have taken 12 hours or more. I should really post a new guide with more complete info.
Thanks for the help guys!

Now that I have root and S-Off downgrading from 1.84.666.2 to 1.34.666.1 using the processes DVDWSN did. Now I thought I could go back to 1.84.666.2 using OTA like I upgraded the first time. But when I try to do OTA, I get the message I do not have any new version. What gives?

If you are trying to downgrade do not touch OTA updates lol. Anyways, what you want to do is temp root your phone so you can 'spoof' the radio version the an old one thereby allowing you to flash a radio that can be manipulated. If you aren't sure what to do then try following this guide.

[Q] [SOLVED] Final question before rooting my DZ

Hi,
I've got my DZ a couple of days ago. It's a secondhand DZ. Previously i've used HTC Touch, Touch Dual, TP2, so this is my first Android experience. I did lots of ROM playing on previous winmo phones, but after reading for these couple of days of Android modding, i learn that flashing another Android ROM is not so simple as winmo ROM.
This is my DZ info:
Android version 2.2.1
Baseband version 12.28e.60.140fU_26.04.02.17_M2
Kernel version 2.6.32.21-g6e170e7

MICROP - 0425
RADIO - 26.04.02.17_M2
eMMC - boot
Dec 13 2010
I've check with root checker and Titanium Backup, it says NO root access.
I've learned that with 1.82, i will have to downgrade first to 1.34.
In the steps for downgrading, i found that i will have to flash signed PC10IMG. But i also found in the sticky thread there's a warning, not to flash signed PC10IMG if i have S-OFF. So before i can downgrade, i have to get the S-ON.
I've read in a thread :
If for some reason (sending phone for warranty or repair, etc) you want to go back to S-ON:
- If you got S-OFF by flashing an Engineering hBoot, download the official HTC RUU for your phone version and flash the stock firmware back again. S-ON will be restored. This forum contains many threads with official RUUs.
- If you got S-OFF with gfree, it saved a backup copy to your SD card called "part7backup-xxxxxxxxxx.bin". It can be flashed back from a terminal emulator or from an ADB shell:
"dd if=/wherever/your/part7backup-xxxxxxx.bin of=/dev/block/mmcblk0p7
The problem is, i got a secondhand unit without microSD card. How can I get S-ON? I don't know how (what method) my DZ got S-OFF at the first place.
Any help is much appreciated.

I've check with root checker and Titanium Backup, it says NO root access.
I've learned that with 1.82, i will have to downgrade first to 1.34.
In the steps for downgrading, i found that i will have to flash signed PC10IMG. But i also found in the sticky thread there's a warning, not to flash signed PC10IMG if i have S-OFF. So before i can downgrade, i have to get the S-ON.
I've read in a thread :
If for some reason (sending phone for warranty or repair, etc) you want to go back to S-ON:
- If you got S-OFF by flashing an Engineering hBoot, download the official HTC RUU for your phone version and flash the stock firmware back again. S-ON will be restored. This forum contains many threads with official RUUs.
- If you got S-OFF with gfree, it saved a backup copy to your SD card called "part7backup-xxxxxxxxxx.bin". It can be flashed back from a terminal emulator or from an ADB shell:
"dd if=/wherever/your/part7backup-xxxxxxx.bin of=/dev/block/mmcblk0p7
The problem is, i got a secondhand unit without microSD card. How can I get S-ON? I don't know how (what method) my DZ got S-OFF at the first place.
Any help is much appreciated.

You are already S-OFF? I'd find it strange that you'd be S-OFF and not be rooted.

install rom manager and check if there has been a recovery already flashed. Might answer your question
Why do you want s-on? S-off is a good thing

You can check if you got S-OFF or S-ON
by entering bootloader
Power off your phone, then, hold the volume down key and the power key.
You might need to disable fastboot

I've already installed Rom manager and there's no clockwork recvery installed.
I want to flash custom rom. I need a root to do that. To get a root, i need to downgrade. To downgrade, i need to flash signed pc10img. And there's a warning here that said DONT flash pc10img with S-OFF. That's the problem.

I already did that. Bootloader says VISION PVT SHIP S-OFF. So that means i definitely have S-OFF.

I've learned some more from the post here and there. I think i figured out what happen with my DZ. I think the previous owner rooted and S-OFF the phone in the old firmware 1.34 then got an OTA update to 1.84. That update destroyed the root but somehow still S-OFF.
If I follow the direction in this thread, i assume that i can downgrade and root again. I will not need a goldcard to downgrade because currently i have S-OFF.

I am not sure whether it will work. But I am curious too.
I once upgrade via OTA and then I downgrade it following the instruction as per your link reference too. I rooted succesfully.
But, my DZ was S-ON.
Now you are in a different situation. You want to downgrade and root it but you already S-OFF.
Do you want to try it?
Cheers

I guess i have to try it.. will report after trying. Thnks all for the help..

Your theory on the previous owner having used the over the air update after rooting seems right to me. I've read more than a few times it will still show S-OFF but not be true S-OFF. Because you can't get S-OFF without root (well surely not on the newer 1.82's)

I'm not familiar with the 1.82 issues (why normal root methods fail on 1.82) but I wonder if temp root works, if you have radio S-OFF and temp root works it might be as simple as:
1. Obtain Temp Root (even Visionary could work)
2. Flash CWM Recovery (I'd use the flash_image method and not ROM Manager)
3. Reboot into CWM recovery
4. ...
5. Profit (Install a new pre-rooted ROM)
Of course this all depends on if temp root works with 1.82 and if your S-OFF is really S-OFF but it seems like a quick & easy thing to try.

I did it guys. It went smooth. Still needs goldcard though due to unmatched CID.
I'm on 1.34, rooted and S-OFF. Next find out ROM that i like most. Any recommendation? it has to be cool and fast..
So i figured that the warning "do not flash signed PC10IMG if you have S-OFF" is before we have the misc_version method. With misc_version "main is older" problem will never occur, provided misc_version done correctly.
Thank you all guys for your help and time especially for those guides starter. You guys are the ones who make this forum SO GREAT!

Congrats .
The first time I did after rooting was install ROM MANAGER premium version.
There a lot of rom to try with the easiest way..
Good luck
