Desire (Bravo) - HTC Shipped Android 2.3 - Let's unlock the bootloader

Hi,
a few days ago, HTC released a developer version of Android 2.3 for the Desire on
http://developer.htc.com (they changed the developer web site now and maybe it isn't available any longer).
Fact is: Everyone who installed this ROM is currently unable to root it or downgrade it again because HTC added a new locked bootloader.
This thread is ment to work together to find ideas how to unlock the bootloader again.
It's known that HTC announces the official bootloader unlocking for all devices already. But nobody knows for sure, how long this will take and I bet here are a lot of people who don't want to just do nothing and wait for HTC to release it.
So, let's begin. Maybe there are also some advanced members who can support us.
At first the questions:
- How is the bootloader lock implemented (does it just have write protection or is there encryption involved)?
- How were bootloaders unlocked in the past?
And last: Even if we don't get far, it's worth a try! And we will gain important experiences. I personally love this.

I like the idea. How about xtc clip? Would it work with this boot? Or maybe we can write a petition to htc or do the while fb thing when they changed their mind and get us gungerbread. U would not mind even paying to get it unlocked.
Im sure if all of us donated to alpharev or unrevoked and get them to start working on it asap its possible?

Why not wait for either alpharev or unrevoked or both of them to release something. They do support out device so I don't see why they wouldn't try to find a way to unlock the new hboot.

I spoke to htc support and by looks of things our device is not on their list for unloocking bootloader, so we might not be lucky.
I guess wait for alpharev or unrevoked to come up with something.
So no one knows if xtc clip would work

I find it both amusing and frustrating that they have included a new hboot and yet now say it isn't even on their list of supported 'unlockable bootloaders' from their new htcdev site???

Same thought.

Getting htc to unlock it would be much better than hacks imo.

This page has an upcoming link to download a boot loader unlocker from hTC.
I would find it rather surprising if they have made an exception in this program for just the Desire. Why would they?

Not from that page but go to your htc repair centre and they will downgrade. Im waiting on confirmation from the repair centre

Maybe htc thought like this: "do you people want so much the gingerbread update? Ok you will get the update but, as you wish so much it, you can't go back to froyo anymore! F** you and ur gingerbread update and go buy some new htc devices"
Regarding the bootloader there is a team that create super locked bootloaders, a team that is creating the web tool to unlock it, and the htc head boss that say "htc sensation? ok super blocked bootloaders and possibility to unlock it via web, htc desire? hm ok only super locked bootloaders, we don't need spend to much resources for an older device, .."
Just kidding..But htc should really change its politic!

I can't really see how letting the desire get unlocked by the tool is “spending resources”, rather is it spending resources to omit a phone model, from what I understand.
Even more strange would be if htc pays good money to the service centers (here in Sweden at least this is third party, and not htc firms) to unlock boot loaders if they could have a web tool do it!

Well, every device is little different, have a different bootloader, different versions...That mean more people have to work to create, test, document it..In addition they will have a lot of people that will have problems doing it, so much work for the customer service again only for an older device (from their point of view)..Of course not only htc is like this, every producer want you to buy their new device..

I am quite convinced that the boot loader lock is pretty much the same for all devices and they just have to include (or exclude) the spec for all models.
They do not have to hack it, after all, they have written the source code themselves!

ok
so, can anyone confirm that unrevoked or any other group is working on it?

Official Bootloader Unlock

Htcdev.com just released the official unlock for the HTC Desire.
Does this help anyone or mean anything at all?

An 'official' method released by HTC to try and 'break' our phone? How is it a disadvantage. LOL
via xda app

You guys mix something up here. So I think I should bring light into the darkness.
Firstly, what is a bootloader?
The bootloader is part of the phone's Firmware. It's the absolute basis (like the BIOS in computer). After turning on your phone the bootloader manages, what in which order happens.
What is a locked bootloader?
With a locked bootloader it's impossible to change the software of the phone (Hboot, ROM, recovery). This prevents inexperienced users from damaging their phones accidentally.
Why it's good to have an unlocked bootloader?
An unlocked bootloader has a big advangates (flash a different Hboot, Rom, Kernels, special scripts, backup apps, etc). And so the community (AlphaRev, Revolutionary) developed methods to unlock the bootloader. These methods also bypass the signature-check by the manufacturer (like HTC) which makes it possible to flash custom roms or hboots.
But if that signature has an encryption, it's nearly impossible to modify the bootloader in the explained way.
How works the encryption of the bootloader?
The encryption of this bootloader (digital signature) causes that only the software which corresponds with imaginings of the manufacturer (in our case HTC) because the digital signature can only be openend by one special key.
Is it really impossible to bypass this digital signature?
No. With methods like AlphaRevX can even bootloaders with this signature be unlocked. But this method does not work for much phones. Furthermore, if a phone has this type of bootloader the risk to brick the phone by attempting to unlock the bootloader is much higher.
What is the official unlock for the Bootloader by HTC?
The official unlock for the bootloader removes the encryption of the bootloader which makes it much more easier (or rather possible) to unlock the bootloader.
Do we need the unlock for the bootloader for the HTC Desire?
As far as I understand, no. Because the Desire never had an encrypted bootloader.
I hope, I chould bring light into the darkness.

A bunch of questions:
Anyone tried this?
What the new hboot functionality looks like?
Or it's an updated stock recovery with an option to pick up any unsigned archive?
Is it S-ON after? Possible to S-OFF again?
ps: I wish to try this, but I'm afraid there will be no downgrade the new stuff which could be functionally restricted.
pps: none of two ruu in the archive worked saying "wrong model" for my desire with stock 2.3.3 from htcdev and revolutionary patched bootloader.

no. It lists all the software versions in the documentation and none of them start 3.x

Ok, I've downgraded my Desire to 2.29.405.5 (including hboot). Then checked FOTA updated and got 2.29.405.14. This is what the requirements list demands for unlocking the bootloader (unbranded, bought in EU).
The preunlock package from htcdev had two RUUs:
MarvelCT_UnlockBootLoader_APTG_1.05.709.01_RUU.exe
MarvelCT_UnlockBootLoader_CT_1.06.1401.4_RUU.exe
They had a rom.zip inside with files android-info.txt and hboot_1.04.0000.nb0.
The hboot_1.04.0000.nb0 images are same.
The APTG's android-info.txt had:
modelid: PG7623000
cidnum: HTC__621
hbootpreupdate:13
mainver: 1.05.709.01
DelCache: 1
The CT's android-info.txt had:
modelid: PG7623000
cidnum: HTCCN702
hbootpreupdate:13
mainver: 1.06.1401.4
DelCache: 1
And non of these RUU worked for me saying "wrong id model".
Anyone managed to unlock the bootloader using this tool? Anyone has more information on this stuff?

The 2 ruus doesn't seems for the unbranded desire, but for a branded one..
Just use revolutionary.io.
With revolutionary you don't loose warranty and have full bootloader unlocked.

It should be for unbranded devices because the download link was named "HTC EU".
And actually this file (Marvel_CT.zip) is offered for many of other branded models as well as for HTC EU.
ps: the point is to apply official unlock, not a thirdparty one. It's security issue.

For security issues, then you should leave it locked.
There is no security issues with revolutionary, thousands of people did it with no issues.
With the official one you will be probably more locked than before as you can't go back.

Does annoy me when people give answers like that. I'm sure he knows that we can unlock the bootloader with other methods but that wasn't the question that this whole thread is based around.
He's curious to try the official unlocked bootloader. I'd like to see what it's like and know more about it too. This is why most of us are on these forums. We like to tweak and hack for no real reason other than curiosity

I know people are hesitant though due to the fact it requires a hboot update...

people must learn to talk clearly...if he know the revolutionary method (most people don't know it at all..as every day someone ask how to root the official gb 2.3.3), he must say clearly at the first post (he should say: "I know there is revolutionary, but for curiosity i want try the htc official unlock...")
instead he said only that the htc official unlock doesn't work, so i suggest revolutionary..again he replied don't want apply revolutionary for security issue (what??)
so what u said "I'm sure he knows that we can unlock .." and "He's curious to " are both wrong or only assumptions, as I can know ONLY what he say. this is how to solve a problem in a rational way..my response is given only based on what he said (he didn't said curiosity or revolutionary)
if you want to try the official htc unlock JUST for curiosity, THEN there is nothing wrong, I'm also curios about that.

But your post makes no sense, he clearly said he downgraded his HBOOT, so it
stands to reason he had already used one of the unlocking methods previously
or he wouldn't have been able to downgrade the HBOOt, no?

You are right, I had s-off'ed hboot by rev.io before. That's why I've downgraded everything to make the official stuff work, but no success.
I sent a request to htc support from the official site about this issue but... considering the answer I suppose they still don't know about just published unlock for desire.
What I noticed is that cidnum of my phone (HTC__203) is very different from the one in the android-info.txt file.
Well, technically it's possible to push the offered hboot image without ruu, but I'm not risking... my backup phone is no joy

seems HTC updated link to HBOOT for some devices to PB9920000_Bravo_Froyo_hboot_1.03.0003_R.exe.
Has anyone tried official unlock with this HBOOT?

I think we'll get same functionality as modern HTC models unlocking whose bootloaders was supported first. This question should go to appropriate forum but: any owner or HTC Sensation/Desire S here who unlocked the bootloader using official way? How is it compared to rev.io? Any restrictions?

[Q] I just want to debrand - tell me how?! :)

Hey guys,
I'm due to receive my HTC One X later this week, direct from Orange UK. Big issue for me is the fact that the handset will be Orange bloatware branded. Now I've heard that their firmware isn't actually too bad and has had little customisation. However, what I am dubious of is the fact that Orange take MONTHS to release firmware updates... Incredibly frustrating.
SO, all I should like to do, is get my HOX running the plain and simple stock firmware. So I can receive OTA updates direct from HTC
Now, I'm very new to HTC. This is my first HTC phone since my run in with an old Window's PDA phone around 6 years ago... I became very gifted in the art of debranding and customising Samsung Android phones within the past two years, however HTC is a different game entirely!
Please, can someone give me a simple (I mean really dumbed down) version of how to debrand my HTC, how to root it (if necessary) and anything else in between! I would really, really appreciate it. I am a Mac OS X user, so Mac instructions would obviously be preferable
Thank you all very much for your time!
Eddy

i too am due to get a voda branded HOX which I want to debrand. I'm not interested in rooting or anything... all I want to do is put stock HTC firmware on there which would receive stock unbranded HTC OTA updates as and when they are released....
is there any way to do this yet bearing in mind that I am not fussed about rooting?

Without s-off you can't debrand, you would have to go custom but then you wouldn't get ota updates

Wait to see if somebody can change the bootloader to S-OFF mode and then alter your CID if you want to use the stock HTC firmware and have OTA updates.
Custom firmware can track the latest/greatest HTC firmware versions anyway so you'd get roughly the same end result.

i found this over at modaco but am not sure what exactly has been done:

HTCdev is having problems since yesterday.
It is not completely down: Tonight I was able to follow the procedure by reloading the pages multiple times. It was very slow, but I couldn't wait.
Ah, and yes, the only way is HTCdev for now.

HTCDev ALWAYS have problems... whenever i use it it's either painfully slow or not even working
Just have to wait this one out, i suggest when you get your unlockcode, that you keep it saved somewhere special

Sad to hear that there is no other way @ tha procedure... But if that's the only way then that's how it will be...
Thanks for the quick answer.
Best of luck.

So i call HTC they said a dev expert will call your around 12 AM your time. So i get the call and i answered what's your problem so i explained then he has me get a unlock token from my device and email it to him. He goes okay so your locked s-on right i said yes on Verizon he told me he felt bad and was gonna help me out. So he sends me a new firmware and tells me to flash it so i flashed it in RUU mode and it past verification and installed firmware he changed my cid to super cid and had me unlock the phone via HTC Dev now i will not say who he is as i promised i do not want him losing his job but thank you very much very great full. I then asked why you do it that way can't you just get my unlock code on VZW_001 cid he said not without raising to much suspicion. If your wondering why he changed my cid.
Please comment if you've experienced similar situations.

That was an amazing thing you just described. By any chance, would you mind
uploading that RUU they so kindly sent to a dropbox or other that is easy for you
so's we can fiddle with it? Thx..

What version of sense are you talking about 5.5 or 6.0
You're saying someone from HTCdev site unlocked your Verizon phone? How did you install firmware on a s-on bootloader locked device. Do we have a working bootstrapper i am not aware of?
I know congress just did something making phone unlocking legal again. Maybe that's why he helped you out.

That's in reference to carrier unlocking, not bootloader unlocking.

No I'm talking about bootloader not carrier I am now running cynaogenmod 11 and I was in sense 6 4.4.2 kitkat. They said the firmware was able to flash because he gave it HTC verification keys.
