[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?

How about unlocking a samsung focus after the NoDo 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

Custom Ringtones On NoDo Devices?

has anyone figured out how to add custom ringtones to devices with nodo already installed on them?? i cant believe microsoft is waiting so long to allow people to use custom ringtones on their devices.
i know before the nodo update you had to have the device unlocked with the chevron unlocker but now if im understanding correctly that no longer works with nodo is there anyway to get custom ringtones on wp7 devices with nodo?

Only one way: Flash back to shipped version 7004, then Chevron it and side load the custom ringtone app. Finally, update to NoDo. Notice that you will be able to sideload any app after NoDo update because it is already unlock before that.

how do i flash back bought a used dell venue pro i wanna unlock my device

I have ver.7392 on my Focus. I tried what you said but it doesn't show that option. I wanted to had reset my phone but I have Chevron and didn't want to lose it. Is there anywhere else to check to make sure I have a backup?

if you happen to have an LG phone you can still unlock even after NoDo without previous unlock. Which phone do you have? Here are instructions for LG devices. This works before and after NoDo

The restore will only be available if you updated your phone with Zune software and it will only show on the same PC you used to run the update. If you used another method to update that didn't use the Zune software then you are out of luck, unless you have an LG phone.

I am using the same computer. I updated a friends phone on my computer, but I updated to 7392 a few days later. Someone mentions that Zune saves one backup, but he didn't know if it's one period or one per device.

zune only keeps one last backup. if you connect a different wp7 device to the same zune account it will be handled as guest and it won't let you update (at least here on my PC it didn't with my wife's phone, had to do it on her own zune account).

Is it safe to update from 7.0.7390.0 to 7.0.7392.0

Just a simple question i have a HTC HD7 on 7.0.7390.0 unlocked and i want to find out if i updated it to 7.0.7392.0 using Zune would my phone still be unlocked?

Why would you want to update, when you know you will lose all youur texts?

if you applied the registry key that is around the forums to keep it unlocked for NODO and everything then it is safe, i have it running and unlocked still
hope i helped.. and remember, if anything would go wrong you can allways "restore" with the zune software to a previous version

eh? What are you on about? Why would you lose all your texts from updating? He's not talking about flashing a new ROM, he's talking about updating via Zune

HTC Surround unlocked. Updated to 7392, still unlocked

@ JBC2005. How did you stay unlocked. My phone was relocked when I went to 7390. If I'm @ 7392 now can I unlock from here?

But didnt that happen to people when they updated to Nodo???

Nope. No one lost any text messages by updating to NoDo. People may have lost text messages if, in an attempt to resolve a problem during the update, they chose to hard reset their phone. But that has nothing to do with the update itself.

what do u mean bu the registry key?? When I updated my HTC hd7 I was told to put airplane mode on and update and now its unlock is it the same now with this update?

i mean the registry hack that came up when going to "NODO" update would re-lock your phone. and this would anable you to keep your unlock for further even for this newer update.
i think there is a .xap file now that does it automated. but thats what i did and it worked.. i didn't do the airplane mode for that, i think that was just to fool zune into giving you the update when it wasn't showing up if i remember correctly.
i was busy for a while till i found the right place with the info using the search.
this is the link to the .xap i found in another post http://dl.dbank.com/c0u5q3xic8

No, without a developer unlock, 7392 can't be unlocked. I restored from 7390 to 7008, performed the Chevron unlock, edited the registry to prevent relocking, then updated back to 7390, and the phone remained unlocked. After updating to 7392, the phone retains its unlocked status.

Update will not ruin your phone (Dev Unlocked)
But i found some bugs.
If you let your phone run like 2 days non-stops, daily use, sometime the phone wake up in laggy condition. I mean, everything inside the apps is laggy, not the metro ui. The Metro UI is still smooth, but in people tab, photo tabs, IE... everything is laggy. It forces me to reset the phone.
I don't know if this issue is releated to the reg hack to instant resume apps (for now, maybe Mango will have some kind of new "multi-tasking" that we don't know) .
BTW, just upgrade it.

What do you mean by "edited the registry to prevent relocking?" is it the file where I copy to my windows on my phone??

as i said before, you go and get the .xap file that does the edit for you or you go and look for the registry to edit with a registry editor for your phone
the easiest way to do it is to side load the .xap files that does it for you and then just run it on your phone and you're done.
just get the .xap file i provided from another forum or if you don't trust that then search is your best bet, if you wan't do it manually or do it for you with a .xap
of course if you don't have a registry editor on there allready i would just go for the .xap file that does it for you that i provided on my previous post.
hope you get it this time

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.

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

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.

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

i got an "update available" message. what update is this?

It should not lock. How have you unlocked your phone ?

a update is risk free- ZUNE make before update it a complete backup from your phone- if you get any problems - you can restore it back . 7740 update are o.k- is not affected to chevron unlock

That is the tethering firmware update.

Cannot comment on Tethering firmware stuff as I havent used it but like mirolog said you always get to have a backup so go ahead and try

Maybe M$ need to be more straight when talking about updates lol
