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.

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.

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.
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..

Click to expand...
Click to collapse
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
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...

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
