[Q] How do I re-unlock my Windows Phone 7 after the latest update?

Dear developers,
I downloaded the latest windows phone 7 update, but it seems to relock my handset again ... I just needed the copy paste feature, so can I keep that and unlock my handset again?
Thank you soo much for your assistance.

Try doing a search before you post your question, as it has been answered one too many times.
You can't dev unlock your device once you have the NoDo update. You must unlock your device and apply the registry edit to keep it unlocked before you apply the update.

thanks for your kind support, but u didnt have to draw my attention to the searching part!

Tell us which handset you have...since LG handsets can be unlocked even after the update.

i have a lg optimus 7, so can i still do all the chevron thingy after the update?

Can you create one if you're not from USA nor have a USA credit card?

Are you kidding me.
ignore what people say about your sol, you just have to restore your device to the previous update using the zune software. i did it for my Samsung focus and got my device dev unlocked again. just make sure to do that registry hack to make your phone from relocking when you update it too NODO again.
I currently have a dev unlocked, unbranded, NODO updated, Samsung Focus!!!

here are instructions on how to unlock your phone after NoDo. I did this after upgrading my pristine LG Quantum to NoDo and then realized that I forgot to unlock first. You install the MFG app first by calling a number. Then you change your registry with MFG according to the post. Here are instructions on how to install the MFG app. Note that this works without Chevron. In fact, Chevron will not work after that (and would not even work after that before NoDo).
good luck

[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...

You need Zune beta from here, to restore back.
If you didn't make a backup before updating to mango, you have to flash with either UCJK2 or UXJL2 (recommended), from here. They're both back to version 7004 so after you flash, you will have to update to NoDo.

I'm currently doing it as I type.
Check http://forum.xda-developers.com/showthread.php?t=1152422 for the instruction.
Long story short. To make it easy :
1. Flash AT&T 7004 ROM
2. Unlock & Prevent Relock
3. Open Diagnose Mode ##634#
4. Install New_SMS_Unlock.xap
5. Install Samsung Root Tools from Heathcliff
6. Use the Samsung Tools to create provxml folder in root directory
7. Find unlock.xml from Applications folder and copy it to provxml folder (details on how to do this can be found on the the thread above)
8. Upgrade to NoDo (7390) Don't Unbrand !!! No need to go to 7392, and you won't get update for Diagnose if you unbrand.
9. In 7390, Uninstall your Diagnose app.
10. ##634# again, and your diagnose app will be updated.
11. After this make sure you can read the unlock.xml using *#9908# from Diagnose. If you can see your unlock.xml then you're good to go, if not then you must be missing something.
12. Flash to 7661
13. Open *#9908# from Diagnose.
14. Choose Unlock and press Save.
15. Your 7661 Focus should be unlocked by now.

Mango BETA B2 is available, not official. I wouldnt expect to see the official from AT&T for at least 3-6 months

At step 14, how long does it take? My phone has been "loading" stage for over 10 minutes now. Thanks.

Step 14 can be misleading.
I know that when I did it following those same directions I never got any message that said it was finished or anything, just like you it said "loading." I just closed out and was unlocked afterwords.

Figured it out...

Hey,
Anybody knows how to maintain unlock from 7712 to 7720 ... I reached 7712 and have managed to keep it unlocked ... want to know how hard is it from here to reach 7720 and maintain unlock ... dont have backups, so if I screw up will have to go back to 7004 and start over again

7220 - chevron

Try this. It worked for me on my v1.3 Focus. Still unlocked.
Btw, it says not working on Focus, but it did on mine.
Edit: Actually, if you're already on 7712, I'm guessing this won't work. Probably worth starting over for, though - especially, since you need a backup, as well.

Ok .. will try it soon ... for now happy with 7712 ... any major features in 7720 ?

i didn't care much about what on the phone so i factory restore using

Afterward, i follow the thread below. works like a charm. I had a nodo update and can't seem to remember if you can unlock or not. So i went and restore from the above thread. Total time it took me was about 1.5 hours. Hope that help.

I actually did the last step from 7712 to 7720 ... then went to GPRS settings, saved unlock.xml, saved and rebooted ... Its unlocked ... but I am syncing with zune in airplane mode cos I have a feeling it might get locked again ...
Did not notice anything new while shifting from 7712 to RTM ... Just hope to get better battery ...

This does not work ***VERIFIED***.
This zune version also gives 801812EO Error on Zune Restore attempt.
Backup is a pipedream. The only way back is from 7004 and through the hoops if you do it right.

No need for beta Zune
Since the official update of mango you no longer need the beta version of zune. Do all the same instructions and your phone will have mango (non-beta) and be unlocked

Putting HTC trophy to factory state

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..

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

[Q] on following Mango update guide

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?

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..
Sent from my LG Optimus 7

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!
