[Q] Chevron unlock on HTC - Windows Phone 7 Q&A, Help & Troubleshooting

Hello everyone !
I Just get an HTC 7 Pro, with Mango installed on it.
I love this device, windows phone...
Windows Phone is really a great OS, complitely different from the others (even winmo, which I had on my previews device, which was a touch pro 2)
But I want to go further with the OS.
In fact, I want to chevron (or apphub if possible, but have no email or else...) unlock my device.
But I can't find any way to make it... (I searched so much...)
Change the ROM ? I would preffer to stay on stock rom... (better update possibilities)
Downgrade it ? No, if possible not, I just got it, I don't want to make some mistakes with it Maybe in one year
Chevron is no more possible, no token anymore (and, anyway, I have no possibility to buy something in Internet...)
Can anyone help me ?
Thanks for your futur help
ps : sorry for my poor English

Sorry but now (if you haven't developer account (99$ for Microsoft per year) or student account (find it with google)) downgrade and instal HSPL and custom, unlock ROM it's the only way out for you. (if you want have unlock device)

Email accounts are very easy to get for free (Hotmail, Gmail, Yahoo mail, many others), so I assume you mean that you don't have a student email account. I can't help you there. Do you not have a credit card? That would let you get a developer account easily enough, though they do cost money.
Downgrading the SPL and installing a custom ROM isn't very hard, though you must be careful. That will get you full unlock. Some of them are also updatable, and a few can even use official Zune updates (in theory; I've neve tried) while staying unlocked.

Yep, I was talking about a student account. And no, no credit card... (it's really annoying me... I can't even buy apps like xda or others...)
Ok, I will try to find a rom which can be zune updateble... (that's the main reason why I don't want to quit HTC roms...).
There weren't RSPL on winmo devices... will it be possible to use it to flash a rom, and then go back without flashing it again with RSPL ?
By the way, is there any official roms out there ? there aren't some of curse on HTC's support website.

It not work with trophy verizon...

that's not a problem, I am on GSM 7 pro (europeen verson)

[Q] difference between mango jailbreak and developer unlock?

Maybe the question has been answered thousand times before, but I couldn't find some mango specific stuff.
What is the difference? my Omnia 7 is developer unlocked and it's on the latest zune version. I'm able to deploy my self made xaps but not any kind of homebrew. I found some homebrew that should work on omnia7 with mango, like a wifi toggle, but it doesn't. Even sometimes my own xaps do not work.
Any advice?
a few things
with a jailbreak, you can sideload any number of apps. With a dev unlock you can sideload only 10 (3 if you're a student).
with a jailbreak, you can use TouchXplorer, which is basically a file explorer. This leads to possibilities of editing the registry. You can't with a dev unlock.
most homebrew which uses low-level access (native code) will not work with a mango dev unlock. most of them won't even work with a jailbreak, but some do.
if you're looking for a wifi toggle type app, there are good apps now in the mango marketplace. Try Network Dashboard (prettier) or Connectivity Shortcuts (not as pretty). They both give one click access to wifi, bluetooth, airplane mode, and cellular settings.
in the end, to most people, a jailbreak's main advantage is the removal of the sideload limit. so if that's your thing, go for it. otherwise a dev unlock is not bad.
(there's also something called a FullUnlock, which allows you to run native code... this bit's still under development, so i wouldn't be worrying about this for a few weeks yet.)
Cheers.
Thank you, helped me a lot. So there are many advantages of a jailbreak. File explorer sounds interesting.
Am I right that there is no easy method for me to jailbreak without to flash back to nodo?
All you need to do to have mango "jail break":
1. Apply HSPL/RSPL (see thread: http://forum.xda-developers.com/showthread.php?t=1195647).
2. Flash the new DFT 7720 mango rom (see thread: http://forum.xda-developers.com/showthread.php?t=1255143)
Good luck!

Lets just say unlocked or in future and thanks to Cotulla "Fullunlock".

there was a term on wm4/5
edit: got it , "application unlock" was the name of it back in the wm times
I say "DevUnlock" & "FullUnlock" as Chevron is a DevUnlock. FullUnlock would the closest thing to a "Jailbreak/Root" IMO. DevUnlock allows homebrew (Pre-Mango), but it still isn't low level root access short of Heathcliff's Root Tools, which isn't completed yet. FullUnlock IMO is going to be the future of a real "Jailbreak/Root" solution for WP7 with full root/admin access even after Mango. The perfect example of this is that the registry editors we currently have can't display all directories. The "no information available" message for certain directories like "HKLM:System\."
this is from the wiki "http://forum.xda-developers.com/wiki/Glossary#Application_Unlock"

Should we open a new thread with a Poll? So far we have DevUnlock, FullUnlock, Application Unlock.
I´ll vote for the "FullUnlock" too and I am ready to open a new Thread with a Poll but I will not consider "Jailbreak".
Any more Terms?
Quick question.... Unlocking with chevron, is it the EXACT same as if you were to officially dev unlock it? I don't think so?
If I am correct then there should be a DevUnlocked, ChevronUnlocked and FullUnlocked or FullyUnlocked?

Chevron Unlock is DevUnlock. It just uses a security hole that allowed using a custom server/cert, but in the end it just performs a simple registry change of the DeveloperUnlockState entry.There's a few other hack like the prevent relock registry edit & the unlimited side loaded app one, but these can be done with either Chevron or Official methods with the homebrew registry editors.
Ok, so it is really the same thing... Just a few extras may need to be done to properly devunlock your phone (sideload limit etc.)
Well DevUnlocked and FullyUnlocked sound good. Although a name for a ful dev unlocked phone may not be a bad idea? What do you guys think?

Chevron vs Dev unlock
If Chevron is exactly same as DevUnlock, then tell me: I am registered Dev with HTC HD7, Mango beta2 and dev unlocked phone, I am unable to install TouchXplorer, but as far as I have found people using Chevron are able to install it to Mango (I've tried official deployment tool and Xap Installer too - error in both cases)
I have also read, that with Mango it's not possible to install application using ID_CAP_INTEROPSERVICES capabality - most of Homebrew apps got this.
So is Chevron really same as dev unlock?

The only people I have heard being able to side load INTEROPSERVICES are Samsung users. It is in my opinion that they're getting an incomplete update process that doesn't properly update pacmaninstaller.exe, which is the exe that installs XAP & has been taken apart & found to have the block for INTEROPSERVICES. All Chevron does is apply a registry change, the same registry change that the official Dev Unlock does. It just uses a custom cert installed through a security hole that was fixed in NoDo.
Install other language
Now this is really interesting! If I understand it correctly, the only chance for me with dev unlocked HTC HD7 with Mango beta2 to enable other language, Czech in my case, is to downgrade to NoDo using my backup, install the registry changes and then go to Mango. That's not an easy solution for Czech WP developers
Too bad there is no "hack" for enabling interopservices in Mango, it wil be much easier then

All you need to do is a registry hack? If so & your have TouchXplorer sideloaded already from when you were in NoDo, you can create a CustClear.provxml with those registry values. Copy it to your phone using the USB Storage enabler & than move it to \Windows\ with TouchXplorer. Than just run HTC Connection Setup. It'll import the registry changes in the CustClear.provxml.

I know about the HTC Connection Setup registry trick, but I joined Dev like two weeks ago... until then I have not used any hacks or sideloaded apps. And now with Mango beta2 I can't install TouchXplorer
I got a plan - once final Mango is released in Zune, I'm gonna restore NoDo backup, Dev unlock, do all the registry stuff and then install final Mango using Zune...
Edit: When I remove the ID_CAP_INTEROPSERVICES from TouchXplorer XAP, it installs now, but it shows no entries. Same for DiagProvXMLv0.7 - it installs when I remove the line, it even looks like it's working, but no matter what entries I add using this app, nothing happens.

mango update quick question need help please,

HEY
i see the mango update is starting to go live for people and after looking at microsoft site its shows in the uk that o2 are givng out the update.
my question is i have a unlocked htc 7 pro currently using a t-mobile sim can i take this out use my partners o2 sim to see if i can get the update then once updated transfer back to my t-mobile sim?
thanks for any help with this.
did you try to force the update with the zune software (the link is in this forum on a different thread). It worked for my phone and doesn't really use my carrier's network (since it relies on disabling your network connection during the upgrade check). It might work for you without doing anything else.
Agree with last post. If in doubt, force it

If you're too lazy to search for the link, here it is: http://www.wpcentral.com/force-mango-update-early-through-zune-software
I had to repeat the steps a bunch of times to get it right, but it works fine
But take care, this will probably re-lock your phone, I had no problem with this because I already have an AppHub student account, so I can officially unlock it again
But I'm still facing some problems because students are only allowed 3 sideloaded apps, and since this number is smaller than 300, this means that the phone will be Interop-locked (this is explained here http://forum.xda-developers.com/showthread.php?t=1265321), so I can't open any code that use native libraries, so I'm unable to edit the registry to increase MaximumUnsignedApps :S
thanks i found the force link lastnight. got it all to work first time so easy was great thank you for the info.

[Q] Answers INTEROP - UNLOCK for HTC ?

I legitimately unlocked my HTC HD7 with Chevron.
But from what I understand by reading a few posts, HTC devices have an additional block with the line-INTEROP UNLOCK, which does not allow the installation of homebrew applications, unless they are not native Mango.
I wanted to ask if what I just wrote was right and maybe in the future if they fail to address this further block
Thank you very much
all WP7 phones have the "Interop-lock", it just that its being a twat to "Interop unlock" HTC WP7 phones without messing around with flashing roms.
The problem for Samsung / LG has been resolved. While HTC is not.
However you did not answer my question

Your opening post makes no sense
if "I wanted to ask if what I just wrote was right " is your question, then you are wrong, HTC's dont have an "additional block" over other WP7 phones.
you read this article http://forum.xda-developers.com/showthread.php?t=1271963 .
I'll then this question: why even after I have unlocked my HTC HD7 with chevron, but i can not install homebrew applications prior to release of the update Mango?
I was able to install applications that were created with Windows Phone 7.5 Mango, while all previous applications homebrew in Mango give me this error 0x81030120
I just wanted some confirmation what I wrote in that first post.
Sorry, but your grammar makes it had to understand what you are asking......
If you get error 0x81030120 while deploying apps, this means that the app needs interop capabillitys(sp),
Some apps also need to be tweaked to run on mango. just because they ran pre mango, dose not mean that they will run on mango.
My phone is upgraded to Windows 7.5 Pgone Mango
can not I install homebrew applications if they are pre-mango and not native Mango? Right?
Sorry for my poor English

No, you cant. I am in the same boat as I have HTC Trophy running latest Mango. I am not going to bother going back to pre NODO just to get the Interop Unlock.
I will hold out hope for someone hopefully figuring it out.

[Q] At the moment, is ChervonWP7 supported or not?

I do followed all the method in this forum.
Install all connection, cer, registry, Zune, SDK, changed another computer
Following the connection solution use WPconnect.exe
But it's not OK
But when i press button Unlock in Chervon WP it shows error about no connection in Zune as you know
So i wonder that at the moment is the Chervon tool supported or not?
Thanks and best regards.

I'm not 100% sure but MS stopped the flow of new tokens and most 2 gen phones are almost impossible to unlock unless you have a dev account but with the new firmware and drivers you can't interop unlock them any more. So I'm pointing towards no they don't support it but I could be wrong.
What about the WindowBreak Project? did it support 2nd Gen Samsung devices? I read it, but forgot!

Oh yea, LOL silly me, those that are lucky to get WindowsBreak to work can unlock.
@hoangchaunguyen: If you mean the original ChevronWP7 Unlocker tool, you must be joking. That thing was never supported (it was taken down almost immediately, though a number of sites mirrored it). It only worked on the first few builds, 7004 and 7008; by 7389/7390 (the earliest NoDo builds, depending on your device) it didn't work anymore. That was most of a year ago.
If you mean ChevronWP7 Labs, they are currently unable to sell any more unlocks. It has been hoped and postulated that they'll get more at some point, but nobody has said anything definite to that effect yet.
