My friend stumbled on a samsung focus windows phone 7. It had the nodo update 7390, ive tried to use chevron unlock to install some of the xap's that helps prevent it from relocking it when updating it, but the chevron unlock wont work at all i keep getting the error that says i have to make sure my device is connected and zune software installed but i do have everything set up correctly and still i get that error Can some one please help me? Am I missing something? i know i have done it before but now it just doesnt want to work anymore. Thanks in advance
I am facing the same issue, I had my Samsung Focus chevron + interop unlocked and upgraded to Mango. All was well, I decided to upgrade memory, hence I installed a 16 GB micro SD card. For installing it I had to reset the phone. Now to have it unlocked again, I tried restoring to my previous restore point 7008 version, which didnt work, probably because of the change in the memory size, I restored to 7008 by removing the micro SD card but now I could not manage to get unlocked again, I suppose Chevron labs certificate has either expired or they have disabled the feature to unlock using the chevron tool.
Please provide me an alternate method to developer unlock my samsung focus or a method to install micro SD without resetting.
@ZeroBreak: it's quite well documented online than ChevronWP7 Unlock doesn't work on NoDo. You need to be on build 7004 or 7008. It wasn't supposed to work at all, and was "fixed" in 7389 and later builds.
@amyth1884: Changing the storage always requires a hard reset, and as you noticed, you can't restore a backup from a different storage size.
For both of you: There are other ways to get dev-unlock. Marketplace developer account is the official way ($99 unless you're a student). A semi-official Chevron WP7 Labs has been "coming soon" for a while, $9. Anybody who has an official account can also unlock multiple phones, so if you've got a friend with an account but not using all his or her unlock slots, that may work.

Yesterday I unlocked my phone with Chevron. I thought I applied the setting in Samsung tools to prevent relocking but apparently not. Today it's locked again and no matter what I try, I can not get it to re-unlock. I followed all the steps here: http://forum.xda-developers.com/showthread.php?t=918710 several times with no success. Are there any other things to try?
Thanks
Did you install a update or just sync to Zune? Not sure what you have done that caused you to lock back?

Just synced with Zune. This happened yesterday. Then today, I got my pre-nodo and nodo from AT&T. Tried it again, post nodo, and still no luck unlocking.
Well if you have NODO now you wont unlock again, but if you go back to restore point to previous version then you should be able to unlock again and then add edit to registry to prevent locking, then do the update.
Ah crap. I didn't realize I couldn't unlock with nodo. So how do I roll back?

Check zune device / update. If there is no "restore" button, so probably zune deleted the rollback files (they are very big > 5 gb)
Ok. I rolled it back but still have the same issue. I'm wondering if this could have caused a problem. My home copmuter was the main zune partnership with my phone. I wanted to unlock it while I was at work so I changed my work zune from "guest" to main. I then unlocked succesfully. I added some apps and everything worked. When I got home, I installed developer tools on my home computer but could not get xap's to install there. I think it was because it was no considered a guest. Not understanding this, I opened Chevron and clicked re-lock. It changed to "lock" so I tried to re-unlock it and have had issues ever since. Even back at work, where zune Sync Relationship is main, still no luck.

So now that you have it rolled back, what is the version of the the OS?
os 7.0.7008.0
firmware 2103.10.10.1

OK, well when you did the update i am sure you also had to update zune before you updated phone, right? Maybe on the computer that you didnt use, work or home, use the other computer but unistall zune and try to install the older version of zune, then try to unlock. The zune update maybe preventer for chevron to read correctly. Now this might not work but i think it should.
I tried everything I could think of. The only thing that worked was a hard reset. I am now unlocked. I went into "Samsung Tools," and selected "Prevent Device Relocking." I have sync'd with my comp several times and it appears to be working. It has not relocked. Is it now save for me to proceed with the NODO update once again? I don't want it to relock and have to hard reset again so I want to be sure.
Thanks
Mine was unlock before nodo updated to nodo and everything still worked fine, so maybe you'll be ok.
Wp7 Focus
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.
I received my replacement phone from ATT (Samsung Focus) and proceeded to do the chevronwp7 unlocking thing I did with my original device, everything was working fine until I noticed this update where Zune mentioned something about 3rd party certificate issues...
I like an idiot updated anyway, now my phone is locked again. When I tried to use the Samsung Registry app it says (license was revoked by microsoft).
I tried to do the factory reset, but the firmware remains the same version, I tried to use the backup Zune made, but the same thing happened when trying to use Samsung Registry app.
Also the Chevron WP7 program I'm using won't unlock the device again.
Please help?
Do you have a backup in Zune? Phone, Settings, Update.
If you don't then indeed, you have a problem.

Unfortunately, the security update blocks unsigned certificates from running on the phone, like the one needed for chevron wp7. You'll just have to wait until a method for unlocking from NoDo is discovered.
Hello all,
I have been able to deploy xap file up until today.
Nothing changed except for me installing Tango on my Samsung Focus the other day which I uninstalled because it didn't work well.
Today I tried to install another xap and it's telling me to connect my phone.
I have zune running and it sees my phone and it has synced without any issues.
I did the same on a HD7 and it worked fine.
The Samsung Focus has mango 7720.68 with chevron and interop unlocked.
What I've done, reinstall wp7 sdk 7.1 and zune 4.8.
Any help is appreciated.
Thanks
Anyone know what else i can do, short of factory reset?
Thanks
Nope, had that exact same issue about a month ago. The only thing I could do was a factory reset.
Did that remove the chevron unlock, if so, can you still unlock if you had provxml or will need to go back to pre-nodo and unlock?
Any idea what could have caused it?
it should remove your chevron unlock, yes.
Silly question, your phone is not under lock screen when you try to deploy?
Another silly question, can you open other applications which were sideloaded?
In case yes for both questions, try a newer version of xap deployer, like the one that comes with the new Windows Phone 7 Market Place. Also, try this tool http://wptools.codeplex.com/, does it work?
In case no for the second question, you lost your unlock somewhere.
Restoring an old ROM is just a workaround the issue, but if you don't wanna try then I guess restore away!
Phone is on and lock screen unlocked (i can see tiles)
All sideloaded apps work.
The xap deployer does not work (check attachment)
If i do factory reset the phone, will it also remove the provxml that was loaded to the file system, or will it keep the unlock in the diagnostic tool so that i can run it to unlock?

Try rebooting your computer a few times and use a different USB port. Sometimes my computer would lose communication and not deploy to my phone until I rebooted it if you send many xaps that use COM interop to it. Weird quirk.
maybe you have again to register your PC with the ChevronWP7.reg (for PC registry)
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsPhone\ProxyPorts]“DeviceReg”=dword:000069C5
I think the problem had to do with the interop lock

Yes that makes sense also due to the fact that you need Interop unlock in order to run COM Interop.
I've done this, also used another computer on which I used to deploy xap, same thing on that.
Used different USB cables as well.

I had mango without the interop unlock and was able to sideload apps.
I have applied the chevron and interop unlock using diagnostic menu on Samsung Focus multiple times, however, it did not work.

Soooo you have tried HeathCliff thread on how to INTEROP-UNLOCK Samsung phones?
The phone did have the interop unlock, i've even applied the wifi tethering, so i know it was interop unlocked.
Nothing worked so I just loaded 7004 and went from beginning.
Thanks all!
I desperately need help
I purchased a Samsung Focus 1.3 ATT phone about a month ago.
Which I was able to chevron unlock and upgrade till Mango.
Later, now I thought of increasing the memory to onbaord 8 GB+ 16 GB micor SD card.
In order to install the memory card, I would have to reset the phone, so that it recognizes the newly installed memory module, I searched high and low and could not find any resource to install the micro SD card without loosing the developer unlock.
Hence I decided to reset it, once the memory module was installed I tried restoring it to my first restore point where I could re unlock my windows phone. The first restore point had ver 7008 which is pre nodo. But since the memory size was different the restoration failed.
So I decided to remove the memory card and then restore it to 7008, which worked but now I am unable to chevron unlock, I have also tried flashing the factory rom to version 7004 and then trying, still no success.
Somebody, please provide me a solution or please unlock the device for me.
Its done
I finally got it chevron unlocked again
This time I flashed the rom available for Rogers instead of ATT and it worked, I was able to chevron unlock, I am not sure why it didnt work when my cell had ATT rom, which is the actual rom that should be there.
