Alright. Here's the story.
I have a Windows 7 64bit computer
+ lg Quantum.
I recently upgraded to the official nodo upgrade
I tried to jailbreak (unlock) my phone and followed all the steps looking at various guides but i could never get pass the
"Uh oh" cannot commmunicate with your phone blah blah make sure that zune is up and ur phone is connected.
And no, im not resetting my phone
Is there a way to unlock after the nodo upgrade?
and if not is there a way to downgrade your wp7?
if you have nodo, than you can not unlock the device.
must make it before..
jap thats right...

Neither of the two posters above me is correct.
To get an official unlock, you have to buy a Marketplace developer account from Microsoft. These aren't available in all parts of the world yet, but where they are, they are considered the "official" option for side-loading apps. This is available on all phones and all versions.
To un-officially unlock your device, use the built-in registry editor in the LG manufacturer/diagnostics app. http://wmpoweruser.com/debranding-tutorial-for-lg-phones-to-hurry-nodo-along-needs-to-dev-unlock/ has the instructions to do so. Developer-unlock is just a registry key; a little searching on this forum will revela which one (I forget offhand).
To roll back your device to pre-NoDO (which will allow ChevronWP7 to work), connect it the Zune software, and then go to Settings -> Device -> Update. There should be an option to restore to the backup which was made when installing NoDo. Note that this is not reversible; you'll lose everything you did since the upgrade. Also note that while restoring this backup will downgrade the phone, simply factory-restting it will not.
The only reason why I want to unlock my device is so that i can install homebrew applications. Sorry i am not bright in technical areas, what does DEBRANDING your phone do?
and will Chevron work after i downgraded my phone?
Unlocking on LG phones works via MFG even after NoDo
yep, Gooddaytodie is correct - almost . Use the MFG registry editor as described step by step in this guide. This still works AFTER NoDo update. I did not unlock or hack my phone before I received the NoDo update.
You do not need to roll back! You don't have to debrand your phone either. Debranding is a change from ATT-US to 000-88 or something other than your current provider and is required if you want to obtain NoDo "unofficially". This can be done in the registry as well. But there is no need for you to do this.
You also don't need the chevron unlocker (in fact it won't work after the registry hack - but you don't need it because it's unlocked already).
Follow the steps in the link and you will have an unlocked phone. I hope you did not unnecessarily roll back yet .
good luck. If you have questions about steps in that guide, send me a PM and I will be glad to help.

So i have a Focus
and my objective is to jailbreak it
already was, thing is i never patched it so it wont relock and it did since i use the chevron updater to get NoDo
now i want to flash back to where i had no update installed so i can jailbreak
how can i ? if there is a method
as for my objective is to jailbreak it
Kinda hard to understand what you are saying, but I will take a guess at what you are meaning.
If you updated your phone to Nodo and forgot to dev unlock + prevent relock via the registry you can go undo your update by using the backup function in the Zune software... so long as a backup is made. From there do the dev unlock and take the steps necessary to prevent relock, then update to Nodo. Once you are updated your phone will still be unlocked and will not relock.
I did this in my Focus.
where do i go to do the back up on the software i can't find to restore to that previous point
- thank you by the way this is helping !
If you did the chevron update to get nodo... No backup is made. You are out of luck until a nodo unlocker is developed.

Hi all,
I use HTC HD7, I have update my window phone 7 to 7.0.7390.0. after that, I was unable to unlock "Jailbreak" with ChevronWP7, and the application that I have install before was revoke by Microsoft.
Any method to unlock "Jailbreak" on 7.0.7390.0? or anyone know when it available to jailbreak?
Right now a new update 7.0.7392.0 is available to update, am i need to update or do s.th else that can make my phone can jailbreak and install third part application.
I'm really thankful for your reply!!!
as far as I know you can't unlock the phone unless you have the manufacturer registry editor on the device after NoDo. At this point only LG phones have this (MFG). Once you have 7390 installed you have to roll back to your previous backup via Zune software (Zune should have made a recover backup of the phone's state before the 7390 update). Once you are back to before NoDo (7390) you have to unlock the phone (chevron etc.) and ensure you have the registry keys set that keep it unlocked. The instructions for that are everywhere here. Once unlocked you can then update again to NoDo (7390) and sideload apps.
Thanks you very much Mr. derausgewanderte for help, maybe i can't do it as your instruction.
But didn't you know when it available for unlock on 7390? or it will never be unlock forever?
you don't have to search too far and you find that a group of people who are trying to come up with a solution. It's just a matter of time. Patience...

you can use recovery support tools or something like that
I upgraded to Nodo a couple of weeks ago using the chevronwp7 method. I am trying to upgrade to Mango but can't get the unlock tool and sideloader to work anymore. Do I now have to downgrade from Nodo and start the process all over again? Any help would be appreciated.
PLEASE use the forum search...
A) Chevron unlocker doesn't work on NoDo. It's possible to pass the unlock through from pre-NoDo though. Otherwise, you can get a real dev account, or wait for the official almost-free unlock.
B) Why would you use the upgrade hack (often referred to as "Walshing" your phone, after the member of the Chevron team who developed it)? NoDo has been available in all markets for a few months now, and even the Rev 1.4 Focus is getting the official upgrade. That said, there's a tool available to fix the damage that Walshing your phone does.
C) It's possible to upgrade to Mango without dev unlock, though it's a little easier with it. Read the forum.
D) It's possible to unlock the phone in Mango if you had it unlocked in NoDo. However, unless you are *very* careful to follow teps (posted on this forum) correctly, most of the useful homebrew apps won't work anymore.
Again, please search the forum. You'd have saved everybody, yourself included, some time.

you can try this link: http://forum.xda-developers.com/showthread.php?t=1143999 but you need to downgrade to 7004 or 7008 PLease Read Carefully And Follow The Steps.
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..

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!
Hi. So I'm quite new to this and I have done a fair share of googling and searching but I still need some answers. I've got an HTC 7 Mozart on Mango 7.10.7740.16 which is Root Tools Unlocked. Recently my phones been acting up ( the wifi seems to come and go ). I was wondering what is the easiest way to restore the firmware or just reset the phone (much like an iphone restore) while keeping the root tools unlock. Any help will be well appreciated. Thanks :good:
You have to run:
Setting>Informations>More infos>slide down and tap "reset phone".
Depending on your firmware version (the OS version is irrelevant), it may not be possible to reset the phone while keeping the unlock. Don't follow Budniu's directions unless you want to wipe everything, including your data and unlocks. If you've updated the phoen through Zune, or made any restore points manually, you can roll the phone back to the exact state it was in then (before the update, if that's how you took the backup). You'll lose any changes, good or bad, made since then.
Hi! thanks for your replies. The firmware revision number is: 2250.21.40600.061 and the bootloader is 4.6.2250.0 (129193) if that makes any difference.
Your firmware version is compatible with the HTC Interop Unlock hack and the installation of WP7 Root Tools, so if you wanted to do a hard reset and then re-unlock, that could be done (you'd need some way to dev-unlock the phone, though). You would still lose all data currently on the phone, though.
