[Q]dumping hboot from phone/extract from OTA possible? - One (M7) Q&A, Help & Troubleshooting

I was wondering if its possible to dump the hboot to a file for analysis? (S-On) And does it use any form of encryption?

Download any zip with an HBOOT.IMG inside and analysis this

Thanks! A bit confused where to find stuff as I'm a recent iPhone convert.
(Though not unfamiliar with assembly etc as I'm currently pursuing a MSc in EE) just thinking that it would be interesting to look into this S-on/off for my new one as it seems nobody is able to make it happen yet on the most recent firmwares

Certain portions of hboot are encrypted, I believe. The problem is that once modified, it will be unsigned and cannot be flashed with s-on. You would need HTC's signing keys.

Thank you for the reply, I'm aware of the requirement of a HTC signed hboot, I was thinking more in terms of looking for weaknesses and possible exploits to enable s-off on 1.54. Don't have great hopes for success but I figure its worth a shot.

[Q] Some questions about flashing firmware.zip

First of all, I want to say hello to all of you. HTC One is my first HTC smartphone (I'm coming from Samsung devices). There is many significant differences between those two brands when it comes to rooting and moding the software. Still there are some things that are unclear for me and I would appreciate any answers from experienced users or developers.
Some facts about my phone:
Unlocked and S-OFF by revone
SuperCID
Android Revolution HD 12.2 custom rom
Now the main question is: In some cases it is important to update phone with firmware.zip (part of OTA update) file which contains updated drivers, hboot, radio, etc. before flashing newer base of the custom rom. Will my phone stay S-OFF'ed after the update (firmware.zip's contains newer hboots and that's what made me worried).
Thanks!

Your phone will always stay s-off unless you specifically command it to go s-on. (which imo is a pointless thing to do)

You will stay S-off through a firmware upgrade. Once S-off, the only way to go S-on is to set the secure flag yourself
Thanks for clarifying this for me !
One more question. I need to relock the bootloader when flashing the firmware.zip, even if I'm S-OFF'ed right?
In case I'm relocked and S-OFF on hboot not supported by revone, can I still downgrade it to the 1.44 without any problems?
I just don't want to ever use htcdev for unlocking.
You shouldn't have yo lock to flash firmware, I didn't. As far as downgrading hboot, since you have s-off, you can downgrade as long as you don't go to s-on for any reason.
But there's not many reasons to downgrade, your phone will still be s-off, unlocked, and without tampered flag on the new hboot. If it does relock, I believe you can use revone to unlock it again, since you've already used the exploit to gain s-off.
Or you can skip all that BS and flash the GE hboot, which can be locked or unlocked by "fastboot OEM lock/unlock"

Actually, I found a great topic with firmware flashing guide by Volmer http://forum.xda-developers.com/showthread.php?t=2365506.
So I didn't need to relock my bootloader or had to wipe anything. For couple of minutes ago, I've updated my firmware from 1.29.x to 2.24 (with updated touch drivers etc.). Worked like charm I've got the newest hboot 1.54 and still S-OFF and unlocked
Thanks for info guys!

There are only a couple of ways to go back to s-on, and they are almost impossible to do accidentally. For practical purposes, unless you were to accept an OTA that HTC specifically designed to reverse s-off (something they have never done and are unlikely to ever do), you are s-off until you decide otherwise.

That is, unless you go around flashing zips that are labeled "for development purposes only". A few people on here have flashed things when they didn't know what they're doing (and some that know exactly what they're doing) and lost s-off. After that you're stuck with s-on and hboot 1.54.

That is one of the ways, actually. If you flash an s-on package with the p3 partition, where the secureflag is stored, that will do it. While one cannot flash things accidentally, I suppose it is possible to accidentally reset your secureflag if you're dumb enough to flash any old firmware package you find.
If that's you, you're one of those people who has to learn things the hard way, and your phone will pay the price.

As unlikely as all that is, I figured it would be worth noting. Since Murphys law says that if you tell someone its impossible to lose s-off through flashing firmware, they're going to go find the only old firmware package floating around that would break their s-off.

[Q] Since S-ON seems to be different from other devices

And just about everyone with a new phone is currently boned for getting S-OFF, what are the differences between S-ON with the One versus older S-ON phones? For example, I noticed that you can flash radios as long as the CID matches. What else is different? It sounds like living without S-OFF is doable with the HTC One versus previous HTC devices.
Its not at all that different. S-off allows flashing unsigned zips via fastboot. Which include zips with just a radio.img etc.
There have been some phones that had a faulty bootloader applied by HTC that allowed partitions with s-on to be flashed that normally was not allowed.
To gain s-off is always different but what you CAN and can't do is the same.
Right now the main reason people are gaining s-off is to convert to Google play HTC one. Before that only dev and users who knew of the benefits applied it.

[Q] How can I tell if it's possible to S-Off my phone?

So Wind Mobile just recently released their version of the HTC One on August 27th, 2013:
http://mobilesyrup.com/2013/08/23/wind-mobile-launching-the-htc-one-on-august-27th/
http://shop.windmobile.ca/ProductCatalog/Handsets/HandsetDetails.aspx?id=HTC+One(WINDCA)&color=green
From a little bit of researching, it seems like there are some prerequisites for performing S-Off. From what I've read, it seems to be the following:
Phone must be an older release as the newer hboots cannot be S-Off
If you are an older hboot, there are certain radios/firmware(?) that prevent S-Off in combination with the hboot
You must be on the stock rom
I'm worried that my new HTC One is too new to be able to S-Off as it was just released last week from the carrier. Also, because it was just released there are no RUU that can be used to downgrade the hboot(?). I'm assuming my understanding is correct.
As of right now, the phone is completely stock, no modifications have been made. I was wondering if anyone could tell me how to perform the following:
Install CWM Recovery
How to make a generic Nandroid so that anyone that needs to go back to stock Wind Mobile can use it (since no RUU is released)
If S-Off is possible given the current hboot and radio/firmware combination currently installed.
How to SuperCID this phone
How to keep S-Off and install hboot 1.54/5
I appreciate any help, I've attached a picture of my bootloader to add more details into my inquiry.

[Q] need to downgrade hboot from 1.55 to get my s-off back

Can anyone point me in the right direction to either get s-off for HBOOT 1.55 or a tutorial or video on how to downgrade back to a version of HBOOT that I can run S-OFF on. I did the Sprint OTA 4.3 and need a little help.
I'm sorry to say it, but you can't s-off when on 1.55, nor can you downgrade. I found that out for myself.
I also did the OTA 4.3 upgrade with S-off on Hboot 1.44.
I now am on Hboot 1.55 and can unlock/lock my bootloader using the unlock code.bin I saved from HTCdev.
I cant believe I thought S-off was the same as unlocked bootloader....
Now im stuck with 4.3 BOO
How did you guys lose your s-off? I did the 4.3 OTA when I had s-off already, and I didn't lose mine

I was downgrading and upgrading and some things went wrong. I was stuck in recovery. Through the process of getting back to stock I guess I messed up.
At least I heard that the Devs are working on 1.55 : )
I found this but, its For ATT, and I don't really know if it would work.

So if anyone knows if a nandroid backup will restore everything, even hboot 1.55 to 1.44, I would love a link so I can download yours since I upgraded to windows 8.1 with a fresh install before backing up mine...
Also, if I have S-ON, which I cant tell except for the fact that I cant downgrade, why can I lock/unlock my bootloader?

No a nandroid does not contain the hboot. Sorry but you'll have to wait till some dev manages to s-off the newest hboot. You don't seem to know what s-off really means so don't worry, I'm sure you'll never need it.
Anyway here's a quote for you to read
In their devices, HTC have installed a sort of security check whose level is determined by S-OFF/S-ON. Essentially, this security level is a flag stored on the device’s radio that checks signature images for any firmware before it is allowed to be written to system memory. This hinders using any custom ROMs, splash images, recovery etc., and also restricts access to the NAND flash memory. However, when security level is set to S-OFF, the signature check is bypassed, allowing a user to upload custom firmware images, unsigned boot, recovery, splash and HBOOT images, as well as official firmware that has been modified, this enabling maximum customization of your HTC Android device.
Furthermore, S-OFF also reduces restrictions on accessing the NAND flash memory on the device, allowing all partitions (including /system) to be mounted in write mode while the operating system is booted.

Okay so as I understand it. When a developer says need to be s-off to flash a rom they do mean it ? or is it some special firmware you are talking about. I had s-off and lost it because I didn't do my research. I'm very disgusted with my self now i'm on H-Boot 1.55 and stuck... also I heard the devs are working on this h-boot to get s-off. Can anyone tell me if this is true?
I was able to flash the viperone rom with S-On without any issues. well may be couple at&t apps which i erased but other than that-Lokks okay for now.

You're really not missing much by not being S-OFF. As far as ROMs are concerned, it's mainly for custom boot screens.

Oh really? Are you sure about that? Explain to me how we never had custom boot animations until we achieved S-OFF and also explain to me why everything I've read on the topic has been wrong. There was no reason for you to be rude about it. A quick Google search tells you all that you need to know: http://android-revolution-hd.blogspot.com/2013/06/do-we-really-need-s-off.html
With S-OFF you can:
Flash in fastboot original parts of the firmware like: Trust Zone (tz.img), Resource Power Manager (rpm.img), Advanced Digital Signal Processor (adsp.img), bootloader (hboot.img), Radio Config Data (rcdata.img), Splash Screen and others, very often device specific firmware like Consumer IR (cir.img) for the television remote controller in HTC One.
Flash in fastboot custom parts of the firmware above, however I've never seen in my life anyone compiling custom rpm.img or tz.img. I've seen custom bootloaders and Splash Screens only. You can also flash modified radio.img but there is rarely anyone out there who does this.
Use more advanced fastboot commands, for example you can change the CID (Carrier ID) of your device or even MID (Model ID). And this one is the most important one in the context of this article.
Reset the Tampered flag, so your device does not show up as "Relocked" if you relock your bootloader.

Maybe I slightly misread your post. You said main thing is "boot screens" you mean splash screens maybe? If so yes you do need s-off, however you don't need s-off to flash custom boot animations. Most importantly flashing a splash screen is not the main reason someone would need s-off, and I am sure the many users of this forum who have flashed a 4.3 based GSM Rom on their CDMA device and don't have s-off would agree.
Last but not least I was in no shape or form rude, even if you did mean to flash splash screens it's still total misinformation that isn't the most important reason to have s-off, it's to save your butt when your in a pickle.

So with s-on can I still flash kernel and radio??? My biggest concern is that I won't be able to flash the kernel I want and the radio also when there's an official update how can I get that with custom rom I stalled? I rly miss having s-off rly does anyone know of a paid site who can do that for me?

[Q] Where do I start?

So here's the deal: I bought a HTC ONE back when it was released and I've enjoyed every minute of it, I loved the stock rom - it was smooth and worked like a charm. I have a lot of experience with flashing ROMS, had quite a few HTC phones before this one, but so far haven't tried ANYTHING with the ONE.
I got the update to the latest Android and I noticed there's something about HBOOT 1.44 vs. 1.54 - I checked and I have the 4.2.2 ROM running HBOOT 1.54.
I really want to get into custom roms and start testing a few out; but I have no idea where to start.
Normally I'd pick a guide and work the steps but I'm hesitant now that I've read bits and pieces about this HBOOT thing - I'm not sure what I means, why people are bummed out because they have 1.54 (which I have).
So yeah, I have no idea where to start. Can somebody give me a rundown, some guidelines, what does HBOOT 1.54 mean for me, where do I start?
Thanks,
Michiel.
From what I've read, having HBOOT 1.54 basically means that you can't S-off your device (as this is only available for 1.44). This means that you won't have access to deeper customisation for your phone (flashing different firmware and changing CID). CID determines what region your phone belongs to so this translates to how early you can get official OTA's as some regions get updates earlier than others. Also, if you want to fully transform your phone into a Google Edition HTC One, this is only open to units with a specific CID.
As for firmware, not really clear on what the differences between firmwares are but you can still flash different radios which are a component of firmwares (thus getting some of the benefits of newer firmware anyway).
That being said, you can flash the whole range of custom ROMs and kernels available on these forums provided that you've unlocked your boot loader. Directions for this can be found on the HTC website.
If you want an optimised stock ROM, try ARHD Sense which is basically your stock ROM with many performance improvements (especially when it comes to signal). For more customisation on Sense, you can try ViperOne.
Honestly there are so many excellent ROMs here that you can easily lose days trying every single one. The Google Edition ROMs are excellent too.
Hope this helps!

Thank you both for detailed replies! This helped me ease my mind on the HBOOT-thing. Thanks!
What no one mentioned is that S-off allows you to remove the ****Tampered**** flag from the boot loader.
With S-off you can lock the boot loader. (With S-on it will show Re-Locked)
With S-off you can flash any RUU to return to stock. Without it you can only flash RUU's that match your CID and are newer than your current firmware.
These may not be important to you, but they're good to know before you jump in.

All you have to do is unlock your bootloader via htcdev.com (note, this will wipe your data) and then flash a custom recovery. You can use this tool http://d-h.st/mas to simplify the process.

Oh sweet I think I found something helpful. I just got my HTC one 6 days ago. I'm s-off so no tampered tag. Do I need to change my cid to flash any ruu? Do I need s-on to flash ruu's? I'm with Rogers in Canada. No RUU for me but there are ota's. Can I flash a different ruu and then the Rogers ota to bring be back to stock? I have s off can I leave it off so if the hboot gets updated by a future ota it will be ok? Thanks for any help.

Oh sweet I think I found something helpful. I just got my HTC one 6 days ago. I'm s-off so no tampered tag. Do I need to change my cid to flash any ruu? Do I need s-on to flash ruu's? I'm with Rogers in Canada. No RUU for me but there are ota's. Can I flash a different ruu and then the Rogers ota to bring be back to stock? I have s off can I leave it off so if the hboot gets updated by a future ota it will be ok? Thanks for any help.

No matter what, you should stay s-off, it does not affect OTA's or RUU's in any way whatsoever. To flash any RUU, you need to be with a cid of 11111111
It's not possible for you to flash an ruu for something else and then flash the rogers ota I don't think
