Hello,
My phone has 4 number security code you have to enter when the phone's being unlocked(did in settings, default winmo lock but HTC made an unlocking skin on it).
I've taken out a battery while the phone was on, then turned it back again in 3 hours. I move the unlock image, and as usual dialpad appears asking for security code. I enter as I usually do and it says INVALID CODE. I'm like - WTF? Tried again, nothing. Tried dozens of times, nothing. Reboot doesn't help. Now it even stopped saying INVALID CODE, when you press the unlock button it doesn't do anything.
I had the "lock" feature working fine for weeks.
QUESTION: What to do(without hardreset)? Phone is set to sync when USB connected, Windows Mobile Device Centre says unlock your phone first before sync. I can't do anything, can't make call(i can receive it), can't check messages or anything, i can't unlock it ffs! Help please, any ideas are welcome
you aren't alone,happened to quite a few.
did you recently install swype 3.9?(there are other reasons)
i've not seen anyone get out without hard resetting.
i have miri rom with swype pre installed
maybe there's a way to upload a file to storage card that will change some registry keys? problem will be how to run it

About the only thing I can think of is if you were able to find a way to put something in the \windows\startup folder that fixed it - but like someone here already said - odds are you're going to have to do a hard-reset.
@
It happened to me awhile back...i tried to find a way but didnt manage to find it, i had to hard reset..
anyone able to access to markerplace? i am getting this error since hours ago
Marketplace could not connect to the server. Please check your data connection and try again
working fine for me on o2 uk
Same problem here. Tried Hard Reset before, but problem still occur.
My only way to get access to Marketplace is to uninstall the initial program that was needed when i first tapped on the icon, u should be able to find it in "Remove programs", " Microsoft Windows(r) Marketplace for ..." then soft reset the phone, re install the initial program again by tapping the Marketplace icon.
Then will i be able to enter Marketplace again. But the same problem might resurface after a couple of days or weeks. I know this is not a permanent solution but at least you should be able to download all the necessary programmes that you required. Hope this can help you in a small way.
I have done a lot of reading and research and non of them worked for me or there could be sth I dun understand.
I have installed the certificate, make sure only wifi is on, then plugin the phone and wait for zune to pop up. Than run ChevronWP7. When I click unlock, it does not unlock the phone.
Also, all the sideloaded apps including XBMODDeployer.xap and TouchXplorer.xap is not working. I'm receiving a message that it got revoked and wants me to uninstall the app.
Will not consider hard reset unless that's the last option.
Please help out! Thanks
Many Microsoft Apps kill the Chevron Unlock, but it should be no problem to unlock the device again.
Also I had spend 8 hours in trying to unlock WP7, until i found out, that Skype block the Chevron tool.
Install the certificate and connect the phone with zune when Wifi is OFF! Then unlock your phone. I would say it would be better to unlock the phone only to deploy the config file and change the phone information to hd7. Because everytime you connect to zune it relocks again.

Thanks for all the reply. However I still have not find the reason why my phone cannot be unlocked. I do not have skype installed, but I will try uninstalling other apps and see what I can get.
SOrry I didn't make it clear earlier. When I said wifi on, I mean wifi on only for laptop, not the HD2.
I'm also wondering, from the tutorial I've read. In order to sideload app I need to have Zune running. Is there a way to sideload app another way?

Have a look at the sticky thread, honestly all the unlock info is there. If you follow the good guides there EXACTLY, you will not have a problem. Dont rush it bro and all will be well.
In case anyone was having trouble finding the info, I just thought I would put everything together and make it easy. Sorry if im re-posting anyones info, just seemed a bit spread out. Obviously anything you do is at your own risk, but if you follow it to the letter, you cant go wrong.
I can confirm all of this works.
And as far as the unlock, I didn't unlock my phone until AFTER I got NoDo. And yes, it DOES stay unlocked. Ive already tested, and obviously because of that, side-loading still works as well. You wont need the chevron unlock program anymore, plus it doesnt seem to be working well for alot of people now anyways since NoDo, but the Chevron Ringtone Manager works GREAT without that once you go through the process. Just leave out the part about the Chevron7 unlock tool.
LG "debranding" hack
1. Enable the MFG application by going to the dialer and dialing ##634# then pressing call.
2. Launch the MFG application and enter 277634#*# when prompted for a password.
3. Select the Engineer Menu item.
4. Select the Other Setting menu item.
5. Select the Edit registry menu item.
6. Set the input boxes on this menu as follows:
Select ROOT_PATH: HKEY_LOCAL_MACHINE
Input SUB_PATH: \System\Platform\DeviceTargetingInfo\
Input KEY: MobileOperator
Data Type: STRING
Input DATA: It is blank, but instead of leaving a blank, put in an empty space. As in actually hit the space key once.
Also, if you want to re-brand your phone after the update for AT&T your input should be ATT-US
7. Select Query and write down the result in case you need to re-brand for some reason.
8. To debrand just enter the same information above and leave the input data field blank. The tool will say fail but it really did set correctly.
You can now connect to Zune and check for updates.

While the unlock works as described and I can deploy applications on the phone I cannot debug from Visual studio. The application deploys and it can be manually run but I cannot debug. The following error displays when I hit F5
---------------------------
Microsoft Visual Studio
---------------------------
The application could not be launched for debugging. Ensure that the target device screen is unlocked and that the application is installed.
---------------------------
OK
---------------------------
Any ideas would be appreciated, I've tryied pretty much everything so far including a clean install of the latest VS + WP7 sdk and a factory reset of the phone.
Same here
I have the same issue with debugging that you do. The only way I've managed to resolve it was restoring to a pre NoDo backup, unlocking with Chevron and then updating to NoDo again. I can only guess that Chevron must do more than change that one registry key (or rather, that the phone does more than change that key when it's told by chevron to unlock) but unless we can figure out what that extra step is we're probably stuck.
Your Problem
Well, that is your problem right there, lol. Both of you mentioned using Chevron to unlock. If you are using Chevron to unlock, AND using MFG, well, chances are ur pissing it off somewhere. dont use both. MFG makes it so that you DO NOT NEED chevron with the LG Quantum, not to unlock. and everything else works just fine - the chevron ringtone thing, ect. Thats probably where ur extra step is... ur unlocking it two different ways and making it upset.

No Chevron in my case, I've only used the MFG on a NoDo updated phone. I don't think you can debug using only these registry keys. There is something else.
have you tried actually calling LG and talkin to tech support? I honestly cant think of anything myself... and ive been thinkin about it and working on it since it was brought to my attention. Its LG's software, they should know something.
I guess you could try a hard reset to see if anything happens
thanks for putting this up here. I've discovered this as well a while back and still find a lot of people with LGs that are being told to roll back or reset their phones after they got their NoDo in the WP7 forums. Many people believe what doesn't work with their device applies to all devices. Luckily for us LG included the registry editor right on the device
Your title should include that this works after NoDo and it should be made a sticky!
cheers
ps: you may want to include a reference to the original post by airwa1kin7 for your first part (link in my signature).
I have tried this several times but my phone still shows the following error when I use a SIM other than AT&T:
"This SIM card can only be used on specific networks. Contact your service center for the unlock code"
Any ideas on solving this would be appreciated
And does the "debranding hack" remove the AT&T boot screen?
-FIXED- Seems in my triple checking wasn't thorough enough, for the path's I was including "\" before the path and the whole string was showing HKEY_LOCAL_MACHINE\\ (the \\ being my issue) just fyi for any other spacey people X)
I attempted the registry hacks to unlock, keep unlocked, and change app limit on my post NoDo AT&T quantum and triple checked my registry after connecting to my x64 win7 ultimate machine and trying to load my chevron prepared ringtone. With most package loaders I get an error of an app limit but I believe with Tom's XAP installer along with the chevron unlocking tool I tried after realizing the registry hack didn't work, I get a phone not detected error when it is clearly shown in Zune which I have open during the whole process. Could it be nodo interfering or an issue within windows? Should I try a restore and chevron post nodo? The debranding isn't required for the unlock to have an effect is it? Any advice would be appreciated as I get bored with these ringtones!
-Update: Error received when attempting to deploy XAP to device using Windows Phone Development Tools Application Deployment.
Error - Unable to install application. The maximum number of developer applications on this phone has been reached. Please uninstall a developer application and try again.
-Note: I have never been ABLE to install a developer application so I don't think it's possible I have any to uninstall. I have changed the app limit registry key and it seems to have no effect, unless the problem is that my phone isn't unlocked, would I get the same error if that were the issue? It is possible to unlock post NoDo with MFG right? Wish i could figure out how ...
When attempting with Tom's XAP installer it says Make sure your phone is unlocked, make sure you've connected device to pc and zune launched.
Seems to me the phone just isn't unlocking...
Is it possible to rollback to pre nodo amd attempt? would it better my odds?
its not removing the subsidiary lock from the phone. you are misunderstanding the information. when it debrands, the provider no longer has control over whether or not you get updates and such. the debrand does not remove the logo. check around, im sure someone has figured out how to do that. as far as the unlock goes, it is simply allowing sideloading. not moving over to another carrier. basically you are changing the code to a devel code. if you want to unlock, well i doubt it if that can be done just yet. check around, i might be wrong. but i know that the carriers are not going to release the unlock codes yet, but call your carrier, u might get lucky.
as far as the app limit change goes, the only devices i am aware of that working on at the moment is HTC, but that is only for sideloaded apps. debranding isint required for the unlock to work, but that still does not matter. at the moment, my understanding is that pre and post nodo there is a 10 sideload app limit on all LG devices. the HTC code may differ slightly for whatever reason. your problem is that is just is not possible to do more. when your computer says it needs to be unlocked, it is ALSO talking about your screen, not just the phone. if you are doing something like sideloading ringtones, remember, u can load them, then remove the app that installed them. uninstall, then reload, that way you dont end up filling it up. a developer app is anything you are attempting to sideload. anything you are not getting from the marketplace. it IS possible to unlock post no-do. sounds like u just have too many sideloaded apps. remove some, then try. and make sure your phone is on the start screen.
oh, and I would put the reference, accept that wasnt where I found it. I cant remember where I got all of it, thats why I apoligised for reposting anyones info.

Another useful registry key: Allow max number of unsigned apps
Code:
[HKEY_LOCAL_MACHINE\Software\Microsoft\DeviceReg\Install]
"MaxUnsignedApp"=dword:7fffffff
jlott069, problem was i wasn't able to sideload any apps, so i couldnt have had too many installed. but problem resolved, thanks for the advice!
Now this is just crazy, reflashed my phone. and i hgot all the updates again, now i'm trying to unlock it and once again am having the same issues.... seems like it isn't unlocked after changing the registry keys
-fixed after resetting to factory defaults and trying just the unlock key, i think it has issues trying to do the unlock and 2 keep-unlock keys at the same time
Another odd thing i notcied and i'm not sure what causes it, but either after unlocking my phone or installing touchxperience, i lose the capability to browse the memory via USB mass storage (zune registry hack)
I still have that option, but I dont use touch experience, and i just still have it unlocked. I had to re-unlock it after my update to mango? I dont know why... but it unlocked just fine and im side-loading apps again with no problem. maybe the issue is in the zune registry hack? I duno...

happened to me too when going from NoDo to Mango it was locked even though relock was disabled. I think it's normal and it will stay unlocked if you followed the known steps.
cheers
so after i install mango i think to relock again, will this process still work for the offical mango, thanks
I was exited and tried to use the cab sender batch program and I upgraded from 7720 to 7740 and then 8107 and now on 8107 when I press the phone icon I can't get it to open it will half open then close, anything I do wont work, and now I cant call anyone that isn't in my contacts. (can't access the dial pad)
What I have done:
1: Hard Reset the phone didnt work.
2: Try to use cab sender and downgrade to last working verison of 7740, but cab sender says " no applicable packages"
3: Battery pull
What else can I do?

Not familiar with cab sender hack. I assume this bypasses the need for zune. Zune does a backup that could be used to restore previous versions of the os. If you have done previous backups, you may want to consider the zune restore process, reverting to a previous is version. Then you can allow the normal update process to take place.
Good luck.
Actually that worked! Thanks, so if anyone else has this problem, what I did was restore with zune and then I just went from 7720 to 7740 with the cab sender because I knew that was the last working version.
DVP phone app error
can't seem to find a backup file before my 8107 update is there another way to roll back/ downgrade cab files or force update a different cab file?
