Chevron Unlock not working anymore on older software versions - Windows Phone 7 Q&A, Help & Troubleshooting

I decided I was going to retry getting my HTC Arrive back to Mango and keeping Interop Unlock.
So I flashed it back to Nodo, then went to run the paid version of Chevron Unlock and it now gives a message saying your phone is not on the newest software version please update then re run unlock.
So is this something they have changed now, is there no way for me to unlock Nodo anymore ?

Just had confirmation from Chevron that this is the case, MS made them only unlock Mango and newer

Putting HTC trophy to factory state

Hey, just something quick. I'm running teh Mango beta but i keep hearing about the pros of unlocking your phone. So I wanted to unlock. I recieved this phone without the NoDo update, since it downloaded that when I first used zune.
So can I just click return to factory settings on the phone and then use chevron? then go through all the effort of updating back to mango.
thanks
no u cant..

No ...its not that simple...
Sinse your phone has nodo and its not unlocked you cant use chevron to unlock.
You must first flash a pre-nodo rom (7004 or 7008) unlock with chevron and then update all the way up to mango
Roms for trophy can be found here

To reinstall chevron unlock from NODO can I roll back to pre-nodo?

Title says it all. I have my pre-nodo back up but I don't have the original launch version of the OS. At first I didn't care that nodo re-locked it. My HTC surround is not even my main device anymore. Still, I figured it be cool to unlock it again before going Mango. If I am unable to do the chevron unlock from pre-nodo is their currently any other way to unlock the device w/o a student account or paying the $99 developer fee?
prenodo is the only other way... restore ur prenodo back then unlock it...
I rolled back to 7390 and am having trouble unlocking. Can it be unlocked from here? I'm getting:
please make sure it is connected using usb
please start zune application
Edit: just searched and read that I can. Is it possible to flash 7004 without a backup? This is for an HTC surround
yes if there is a rom available u can flash it...

[Q] on following Mango update guide

I have a Samsung Focus that I am trying to update. I am trying to follow this guide:
http://forum.xda-developers.com/showthread.php?t=1101344
However, I don't understand this part:
Code:
4. Run Application Deployment, click on browse
--- for hTC phones, click on TouchXplorer.xap
--- for Omnia 7, click on WP7RootTools 0.5 alpha.xap
-- and click on open
Does my phone need to be unlocked to follow this? Should I do it with Chevron?

if you are not unlocked and upgrade to Mango you will have a hard time unlocking it within Mango (and won't be able to sideload). Unlock in pre-NoDo and then carry the unlock over to NoDo and Mango following the guide. yes, people have successfully carried their Chevron unlock over to NoDo and then Mango. You need to make sure that it cannot relock when you connect to Zune. The tools listed allow you to make the reg changes to do that.
i thought I was reading somewhere that it's not possible to unlock past 7004 or something like that, which was before NoDo? (using Chevron)

you are correct. I corrected my post. So you need to start with
A. NoDo Update Guide: How To Pass ChevronWP7 from OS 7004 to OS February 2011 update and 7392 NoDo
So let me try to understand that, if my phone is unlocked now and when I update to mango it might might not unlock anymore, regardless if I got a SIM code from htc? I am new into this so I'm trying to get into it lol.......
I have a question regarding the official Mango update for my HTC Trophy. I unlocked 7004 via Chevron, did some hacks for preventing it from being relocked (via this thread) and updated to 7392 (NoDo). Everything is OK, device is still unlocked.
What should I do for preventing my device being relocked during the ongoing official Mango update?
Is there already some solution, or will it be after the official Mango release will appear in Zune?

I think we are talking about two different kinds of unlocking. I am referring to unlocking the phone for sideloading homebrew apps. If you upgrade to Mango you might not be able to sideload homebew apps that allow you to customize your phone until the gurus come up with a solution for Mango. Then there is SIM unlock to be able to use a device with a different SIM. I think that is what you are referring to. That will not change for you if you upgrade to Mango.

If you follow Ansar's tutorial you will see that there are preventions you can take to stay unlocked. You basically finished part A of his tutorial and can continue to part B with prerequisites for Mango upgrade.
B. MangoB2 Update Guide: How To Pass ChevronWP7 from OS 7392 [NoDo] to OS 7403 and 7712
In your case 7712 will be 7720.68 once it is released.
When you have all prerequisits finished from Ansar's post you stop there and are ready for official Mango once it comes out.
Reports from people who were NoDo unlocked and proceeded to Mango are mixed. Some kept the unlock some didn't. If it doesn't stay unlocked you have to have the files ready on the device to be able to unlock it without going back to NoDo. This is what Ansar's post explains. For the HTC you will put a CustClear.provxml file in place that you can deploy to unlock it.
This post also explains how to keep it unlocked. You follow the guide to the point at which it does the actual Mango upgrade. That is where you stop and wait for the official one.
But even if your device is locked in Mango you can go back to a NoDo restore point you created before you went to Mango. All explained in the guides/tutorials above.

You think some of those who followed the Ansars guide or those who just upgraded from unlocked NoDo to Mango without any other hacks before update?
The second link is some other guide than Ansars, if I am right, I can choose which one to use?
Thanks for help!

those who just upgraded. I myself just upgraded but luckily for LG users there is an LG phone tool on the device that allows to modify the registry at any stage.
Yip. That's d mfg menu, and I love it..
Sent from my LG Optimus 7
Today I have succesfuly registered my ISIC student card with validity until december this year into the Microsoft Developer Account.
Now I have Chevron unlocked NoDo WP7 (HTC Trophy) with some modifications to prevent it from relocking during sync etc. I would like to unlock it via official Developer Account I now have.
1) If am not wrong - I should HR my phone, it will go to NoDo locked and then I can use application "Windows Phone Developer Registration" which will unlock my device and it will stay unlocked also after Mango update?
2) Is it possible by developer unlocked device to modify registry entries? I need to add one entry, so I will have Mango in my native language after update.
3) After one year, will it automatically lock my device and I will need to perform new ISIC validation, which will be in that day already expired?
4) If it will expire, will it hard reset or block my phone or will it stay in way it is, but it will not only be possible to side load xap's?
Thanks for answers!

HTC arrive Nodo to mango unlocking

I have a htc arrive and really want to interop unlock it. If I flash my phone back to nodo and dev unlock it is there a way I can upgrade back to mango and still be unlocked?
Developer unlock via Chevron is not possible on NoDo and later updates. You either need OS version 7004 or 7008 for unlocking it via Chevron method.
And yes, it is possible to retain unlock via provxml method, although I am not sure if it works on hTC devices.
You can always flash a DFT custom ROM though
Their is no DFT rom for the arrive also I planned to unlock using dev unlock tool
In that case, flash a 7004 ROM and unlock it via Chevron.
That cant be done because it is a HTC arrive and never had a 7004 rom out

[Q] Will updating from the original Mango release break my unlock?

Will updating from the original Mango release to current break my unlock? I don't remember all the details of how I unlocked, except that I had to roll back to pre-Nodo and then do something with unlock.xml and the diagnostics tool.
Zune keeps nagging me to update though. Do I gain/loose anything if I do?
Thanks
Well I have a Samsung Omnia 7 with a Tmobile germany branding and I always updated over Zune whenever an update appeared.
I unlocked my phone back at Nodo times (yeah interop unlocked) and now I am at 8107.
Never lost any apps/files or the unlock itself.
Thanks, I've just updated and mine seems fine too
