Hi Guys
I purchased HTC 7 Pro 8 GB
Accidentally, I upgraded to NoDo version and now I cannot unlock with ChevronWP7 and manual unlock works only for LG as I understand.
So
Is any way to go back and downgrade?
Thanks in advance
When this happened to me I was able to use Zune to restore my backup and then I installed chevron, unlocked and installed the provvml hack for htcs and then updated again via Zune. Now it is unlocked with NoDo .
Or downgrade is possible with the help of instalation this rom http://forum.xda-developers.com/showthread.php?t=1013807
Moved to general as not rom development.
Thank you guys It really worked.

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
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...

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
is there a way to upgrade from NODO to Mango because im not really sure even after searching around...i had my phone chevron unlocked in pre nodo and upgrade just recently so my phone is nodo and wen i go into chevron is says unlock but can...so if there is a way to go from nodo to mango i would love to know so i can do it..if not i guess ill be waiting till its released
Well, it's really hard to understand your question. If I understood right, your phone is running a ChevronWP7 unlocked WP7 with NoDo installed - is that correct? And now you want to go to Mango (beta) without loosing your jailbreak?

Not exactly, i recently unlocked my phone but it relocked when i upgraded to nodo, i recently reformatted my pc and had to re-install zune and cant go back to pre-nodo...so basically is there a way to go to mango, from a nodo phone that isnt unlocked anymore

Hy guys.
I have made a windows phone 7 app using visual studio 2010, it works fine with the emulator, but i need to put it on my phone.I have an HTC Mozart.
First of all i think i need to unlock my phone, but my os version is 7.0.7390.
I reseted my phone from setting/about/reset , but after that my version is still 7390.
I really need to put my app on my phone, how can i downgrade my os version so i can unlock my phone with the Chevron unlocker ?
Or it is possible to run my app on my phone without unlocking ?
Please help. Thanks.

No. In order to deploy your app to on your device, it needs to be unlocked. Resetting won't help you there, since it doesn't do anything more then wipe the data and bring it back to its factory state. Which means the factory state of your current ROM version. Which in your case is 7390. If you want to put your phone back into a pre NoDo state you should head over to the HTC Mozart forums and have a look for a pre NoDo ROM that you can flash. You'll then be able to unlock your device with chevron and apply all current official updates afterwards. Your device will remain unlocked.
Don't forget about your backup.
You should have a backup of 7008 which can be unlocked (that's what you're looking for).
To check that, Zune, Phone, Settings, Update, there should be a Restore there.

True. I don't know why, but for some reason I didn't even consider that point.
i have restored it ( twice ) but the last restore point is from 5 may and my version is still 7390
I managed to downgrade, i flashed my phone with RUU_Mozart_HTC_Europe_1.23.401.06_Radio_5.51.09.06_22.30.50.09U_by_ansar, it's a 7004 version, and then i unlocked it. I can run my app on my phone now
