Hey guys,
ive posted here and there, looked around but to no prevail, so i got a problem after flashing my Omnia 7 which was on NoDo but not unlocked (prior to this, it unlocked fine)
The STORY - since i updated my phone to NoDo after reseting it, i diidnt have it unlocked but as i felt like going back to Chevron, i flashed it to an unbranded euro ROM but now the Chevron unlocker is not working. And also, i cannot restore my phone since i keep getting an error code.

Your story is not very clear. This is what I get from it:
- Original ROM / Pre-NoDo / Unlocked
- Original ROM / upgrade to NoDo / Locked
- Flashed ROM / Pre-NoDo / Unlocking fails
Is that correct?
Your backup is not working, because you flashed your ROM between backup and restore.
You should provide the following details, or else noone can help you:
- What ROM version did you flash exactly? (eg. I8700XXJK1)
- What are the specific errorcodes / errormessages you get when you try to unlock? (maybe provide screenshots of the problem)

Cool ok thanks alot for the reply.
So in the very beginning, The Original Rom (OPTUS) on 7004 unlocked fine.
Then i updated it to pre-nodo then unbranded it via the registry then i got the nodo update but then i reset it via Phone Settings > About > reset so i ended up with a normal locked phone
Then recently, in an attempt to unlock my phone again, i flashed my phone with BOTH I8700 BSE I8700BSEJK1 and I8700 XEN I8700XENJK1. One of which is a Netherland ROM and one is a Belgium ROM and they both act the same way.
When i try to unlock it, the Chevron unlocker keeps showing the usual message
Sorry, I'm Having trouble communicating with the phone.
- Please make sure it's connected using USB
-Please start the Zune application

and lastly, the restoring, as you mentioned was my initial thought but yeh so thats nothing to worry about
EDIT: Wait, before, i used to be able to open the Chevron Unlocker and tick the boxes and that message would come up but now it doesnt even open the program but just shows that message. Dont know what difference that makes but yeh.

I'm not sure this will help. But try to open this file on your computer:
C:\Windows\System32\Drivers\etc\hosts
Remove every line that contains WindowsPhone in it, and try again.

nup. im sorry, thanks for yourr help but it still isnt working that great. So right now its just the same as before hahah. I uh. Tried to reinstall the Windows Developer thing but it was interrupted but seemed to have installed fine in the end. but maybe thats why i cant even open the Chevron tool?

Maybe you are running software that uses port 443. Look at this thread for more info: http://forum.xda-developers.com/showthread.php?t=938106

[q] nodo jailbreak

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.

[Q] Unable to unlock "Jailbreak" with ChevronWP7 when Update 7.0.7390.0

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...

[Help] New to WP7 Hacking

I'm new to hacking the WP7 and I have a Samsung Focus. I've tried to update to Mango to no avail. I'm to a point now that I know I need to flash to a 7004 ROM in order to install the NoDo update and bounce up to Mangos with all the sideloaded apps or whatever. The only problem is that I can't find out how to revert back to 7004, and I DO have a backup of my Original 7390 and have that backed up about 2 other times just in case.
So my question here is, How can I revert to 7004 and bounce up to the Mango Beta? Or can I go from 7390 to Mango? I tried Chevron but found out it doesn't work with any version of the software besides 7004.
All help will be appreciated.

What error are you getting when try to update?
Is it 80180048?

No...I can't unlock the device to apply the .xap files to it. I'm on version 7390 and need to go back to 7004 for ChevronWP7 to work and unlock my phone.

Just now noticed you have a Nodo backup...you need your pre-Nodo backup... which I'm guessing that you didn't think to make a copy of.
You can't unlock your phone in Nodo... without being a registered developer.
So you need to roll back to pre-Nodo in order to unlock it ... you have 2 options.
I can only assume that you know how to restore to a back up in Zune. In case you don't in Zune you click settings, select phone, click update and if you have a back up then you will have a restore option. If it's recognizing your phone you should have a back up there.
A phones backup is unique to 1 device... so if somehow you don't have your back up you will have to move onto option 2 which is flashing your phone.
There's is one other option... the Chevron team is eventually going to release a unlocking tool for Nodo at a small fee. It's been coming soon since June 17... so only a matter of time.

No. In order to deploy your app to on your device, it needs to be unlocked. Resetting won't help you there, since it doesn't do anything more then wipe the data and bring it back to its factory state. Which means the factory state of your current ROM version. Which in your case is 7390. If you want to put your phone back into a pre NoDo state you should head over to the HTC Mozart forums and have a look for a pre NoDo ROM that you can flash. You'll then be able to unlock your device with chevron and apply all current official updates afterwards. Your device will remain unlocked.

Don't forget about your backup.
You should have a backup of 7008 which can be unlocked (that's what you're looking for).
To check that, Zune, Phone, Settings, Update, there should be a Restore there.

True. I don't know why, but for some reason I didn't even consider that point.

i have restored it ( twice ) but the last restore point is from 5 may and my version is still 7390

I managed to downgrade, i flashed my phone with RUU_Mozart_HTC_Europe_1.23.401.06_Radio_5.51.09.06_22.30.50.09U_by_ansar, it's a 7004 version, and then i unlocked it. I can run my app on my phone now
