I have read the tut for brick/unbrick and downgrade hboot in dev section. And if I read it good there are 2 methods of downgrade hboot
1) brick/unbrick device and downgrade hboot (first post tutorial)
2) change CID and run RUU with lower hboot (second post tutorial)
If these are the options I think the second is the easiest way to downgrade hboot, but why are most people downgrading there devices by bricking it? Are there advantages or disadvantages for each method?
Edit I have hboot 2.15 and want downgrade to hboot 1.06

Changing cid seems to have caused a few bricks for some people when trying to update to official JB OTA.
So would you advice to use the first method, although I already OTA updated to JB?

I have downgrad by the first method and i have test all the way to hard brick my phone
And I can say that it's impossible to hard brick your phone with this tutorial.

I think the issue happend when the cid was already changed on ICS, and you tried to update to JB. Changing it when you already are on JB shouldnt be any problem.
But I havnt done any downgrading myself, so I dont know... Its just what Ive read.

Just to be clear there is ONLY one way to downgrade hboot and that is with what you call option 1.
For what you describe as option 2 that ONLY applies AFTER you do option 1. If you want to run a RUU AFTER you've completed the downgrade you also have to do what is stated in the second post. Although it's much easier to use the the all in one tool kit reset your main version. This is achieved by and pressing the "Main version fix" button using the all in one toolkit. That will save you trouble of pulling mmcblkp23, hex editing it, then pushing it back to the phone.
Alright I understand it, I will read the tut again and try with my nooby knowledge of linux to downgrade

It's a pretty straight forward method. Try not to panic if you encounter a problem. The good news is that it's almost impossible to truly "brick" this phone. Just take a step back and reread the instructions paying close attention to the details. Post your questions about the process in the main thread, the people that follow it typically have a higher level of understanding then the forum overall.
If you don't have the required 10 posts to be able to post in the development sections go post some BS ones somewhere in XDA so you can get into that thread.
Oke thanks :thumbup:, it sounds doable to downgrade with these instructions

I am on InsertCoin ROM and I would like to know if I can update my HBOOT from 1.17 to 1.18.
Is this possible or there is not 1.18 (revolutionary) hacked ?
Revolutionary actually downgrades your from 1.18 to it's hacked 1.17, so upgrading to 1.18 is useless.
Also, why do you want 1.18 since you won't actually benifit/experience anything from it?

Again, why flash a newer bootloader if there is NOTHING to gain from it, risking the possibility of hard bricking your phone, and with pointless "fixes" that are only to undo what revolutionary did?
Its jot an update in any way, shape, or form, and increases your possibility of a hard brick for zero gain.

Maybe start with supercid first
i understood that we need to get supercid before we can get s-off?
So i think we have to start dig around mmcblks with a hex editor to achive that.
i did a little search and i think it could be somewhere in /misc, but don't let my n00biness guide you wrong. they have it in S4 on mmcblk04. i did same mod to my HOSs3 but cid didn't change so the S4-method doesn't work . Does anyone have any knowledge about the whereabouts of the cid?
yes, superCID is starting point for getting s-off

In fact, with this method cid will change. But spl will re-write it back at next boot. So it is not mmcblk0p4.

Just sitting there and doing nothing won't do anything. If you have basic knowledge of the Android/HTC filesystem and some adb commands you can try different things if they work. I'm searching on the internet how other HTC devices got supercid and I try the same thing on the One S. But it's not working out well because of the r/w bug on Trickdroid 6.

Have you ran an RUU before? You can change your CID to its original, the relock your bootloader and run the RUU. If it fails, you can run the ICS RUU then apply the JB OTA.

I am looking for the same answer. no it doesnt say if it will brick or not. but some people have say it will with super cid. you can flash a new cid with fastboot oem . The thread really has no instructions on how to do anything. it just supplies the link for the file.
I tried to flash to ruu via the windows executable file that it came with, but i get an error everytime. 159 image error.
I am original on t-mob though. this may be the prob. im not sure.
everyone else says just have your cid HTC__001. if your s-off you can change it in fastboot.

Firstly: The RUU is meant for unbranded european devices.
superCID bricks phone when you flash OTA. Using RUU should be safe.
So you have no use for this ruu since you are tmob
Hi, I recently purchased an HTC one X and I get a message with red letters saying "this build is for development purposes only do not distribute outside of htc", also my htc has been ramdomly rebooting, I want to go back to the stock ROM because I think I might have a custom one and that can be the cause of the random rebooting.
I have the 4.1 oficial firmware but I am affraid to flash it because my phone can become a brick.... The phone was rooted with SuperSU but I have uninstalled it and checked with titanium and I can no longer get superuser rights(I suppose I have succesfully unrooted my phone), I have also checked on bootlader and I have S-ON so I dont know if I am under conditions to flash the oficial firmware without risk(I dont want a brik). I want the original firmware because of the upcoming 4.2 and sense 5.0 update HTC will be releasing.

Is that all??? with S-OFF there is absolute no risk of briking??
Nonononono there's a tradeoff. Because once you supercid you brick if you ruu while s-on. So you need to s-off so as not to brick while RUUing. Technically because there are no longer security checks you have a greater amount of risk If you do something stupid.

Just flash a stock rooted Rom would be my advice.. what are you gaining from ruu? Look at cleanrom, it's forsurely the most stable for this phone... Just my 2 cents cause if ya don't know what you're doing or are comfortable using adb odds are is you will booger up your new to you phone..

Updated firmware that is not part of the ROM. If you read the top post of CleanROM, its recommended to RUU first. Its not "required", but some folks have found it helpful to resolve some issues, like random reboots.

Nothing you do to your phone can remove all risk of bricking when you flash. There is always a risk.
But if you have S-On and SuperCID, and try to install certain OTAs or RUUs, a brick is certain (known brick condition).

If you are S-on and SuperCID (which your phone likely is), and try to take the 3.18 Jellybean OTA, or run the 3.18 RUU, you will brick.
S-off will at least prevent bricking from this particular condition. The other option is change back to the AT&T CID.

Plenty of guides here how to do that. Let me know once thats done.
Well I have 4ext recovery well pretty much everything I can flash custom just would like s-off so where would I find these ruu because HTC dev don't have them apart from Android 4.0 which is hboot 2.

Can you check CID? That will help us to choose right RUU for your phone.
When you do misc_version successfully you have to reboot in bootloader and start RUU.RUU install from bootloader.Then it will check is your misc_version is ok.
