[Q] HTC HD7 desaster mango update

---

Hi every one ! i have a HTC HD7 from T-mobile and i did the Mango beta update on it and i did not make a backup file, i have been trying to go back to the previous OS settings but all of the programs or ROM that i try running, can not see the phone connected to the computer. I get error 260, not one of ansar ROM can see my cell as been connected even though i check that it is and that active sync sees the phone as been plugged in and the drivers are installed. Can any one help me to do this down grade, please

you'll need to d/l a rom from ansthar, based on who your cell phone provider is.

Please, give some more info about your phone (OS version,Radio software version etc...).
You can find them on your phone (settings - about htc hd7 - more info).
Thanx

the phone is a T-mobile HTC HD7
OS 7661.WP7_5_Trial
(mojobld).20110607-1657 what is this?
Radio software version:5.51.09.11axxxxxxx09U
Firmwear revision number xxxxxxxxxxxx.531
you see i did use the windows phone support tool and i run the tool to its completion but the mango update did not install, than i downloaded a program called "provision" than i downloaded the zune 4.8 than the update started automatically and smoothly . i soon after deleted the window phone support tool thinking that i would not need it again, until i read that i need a back up to restore my phone if i wanted to install the mango update later. will i have downloaded just about every tool out there to restore my phone but when i run the tool it does not see the phone as been connected , i checked and i see the phone plug in my activesync so i was wondering that since mango is installed this programs do not see it since they where made for nodo. your help will be greatly appretiated , thanks in advance

Are you using the new Zune for Mango? cause the old zune won't recognise your phone

try this link Here

See if you can go back with zune... ALWays BAck Up!!

Ok. To what tfn wrote I say YES you should always make a backup and you can do it as it's explained on the link he provided.

For Your phone, since you dont have backup go to http://forum.xda-developers.com/showthread.php?t=876451 and find RUU_Schubert_TMOUS_1.20.531.01_Radio_5.51.09.11a_2 2.31.50.09U_by_ansar.
Download it - this is original ROM for flashing your phone - it will take you back to 7004 version. Follow the instructions in ansars post.
This one worked for me.

http://forum.xda-developers.com/show....php?t=1101344 - here you can follow instructions for updating to NoDo and Mango.

Now some important thing...
1. When you are taking beckup you have to have Zune 4.7 installed (not 4.8)
2. You can also see my thread (it could be helpfull) - http://forum.xda-developers.com/show....php?t=1179095

I hope you will make it!

i will give this a try and thanks for the help

i guess i'm **** out of luck, i did everything as written on the post and I did manage to get the ChevronWP7. ChevronWP7 does not see the phone as been connected , i try the steps with zune4.7 and 4.8 and i get the same message the chevronwp7 can not connect to the phone, also when i run the Application Deployment throws an error stating that the phone is developer locked and i need to contact Microsoft for steps on how to unlock it .

I need some help..can someone with a T-Mobile US phone please list all regedit keys for the HD7. After screwing around with the regedit settings to enable the HD7 read as a storage device, this happened and is the cause for Zune or any other program to not read the phone.. thanks in advance. i need all regedit keys with values and exact name.

Did you get your phone to 7004 version with flashing?
If yes then:
1. send to your e-mail (which you have configured on your phone) chevron.cer in attachment
2. open that mail on your phone and tap on attacment
3. install cetificate
4. in settings on the phone turn on FLIGHT MODE
5. connect the phone to a computer and start Zune
6. run Chevronwp7.exe as administrator
7. check those 2 boxes and press unlock
DONE.

I just did it on mine hd7 (just to be sure).
