[Guide] How to debrand/flash your HTC 7 Mozart

[Casey_boy]

This is a guide on how to flash a new ROM to your HTC 7 Mozart, without using Goldcard. This method can be used to update your ROM or to debrand your phone.

This method was outlined here by theintelligent. I've also used info from here by alalai. I take no credit for discovering this, but thought it deserved a pinned topic to help stop the multiple "how do I flash" topics and to make it easier for users to find the information.

Before you start

This WILL debrand your phone (remove network customisations) and it will enable you to receive updates as soon as Microsoft release them (rather than waiting for the operators).

It WILL NOT unlock your device (to allow you to use other network's SIMs). You will need to use a commercial service for this.

You WILL be able to update your phone to NoDo (and later leaked versions when they appear).

Preparation

I'm not sure why, I think it may be due to getting the right drivers installed, but you will need to install one of the following:

Windows XP users:
Install Microsoft ActiveSync .

Windows Vista/7 users:

Install Windows Mobile Device Center - make sure you install the right version 32/64bit depending upon your OS version.​

Ensure that your phone's battery has at least 50% charge.

Download and flash your ROMs

Yes, I said ROMs - if you want to debrand your phone, you will need to download two sets of ROMs. If you're just updating and not debranding then you'll just need to download one ROM.

1. Download a ROM which is by the same network as you're on (for example if you're phone is currently locked to Orange UK then download RUU_Mozart_Orange_UK_1.22.061.10_Radio_5.50.09.18_ 22.24.50.09U, by ansar. - do not download 1.30!).
2. Open up ActiveSync/Mobile Device Center
3. Flash this ROM to your phone (you may not need to do this step, but most users will).
   • Turn your phone off.
   • Put your phone into Bootloader Mode - this can be done by pressing and holding the Volume Down Key & Power Button.
   • Plug your phone into your PC, hopefully a HTC USB driver will install.
   • Once the driver is installed your phone should display USB mode.
   • Extract the zip file and then run the exe file
   • Run through the update process
   • When your ROM is flashed, your phone will want you to customise it - just do the basic stuff.
4. Download the ROM you would like to flash (e.g. RUU_Mozart_HTC_Europe_1.30.401.01_5.54.09.21_22.33 b.50_RELEASE).
5. Extract the unbranded ROM zip file and then extract the exe file (WinZip will not do this - try 7zip or similar).
6. Copy the RUU_signed.nbh from the unbranded ROM
7. Extract the branded ROM exe
8. Paste the RUU_signed.nbh from the unbranded ROM to branded ROM
9. Plug your phone back into the PC in bootloader mode
10. Run RomUpdateUtility.exe file from the branded ROM (but with the unbranded RUU_signed.nbh file)
11. Follow the steps...
12. Et voila, you'll have (if all goes well) and unbranded ROM installed
13. Last step, plug your phone back into your PC and run Zune. Your phone should receive the latest cumulative update.

Let me know if anything isn't clear or needs updating. I am not going to list all ROMs, but there are a plethora of them available here.

Yes, if you're sure it's unbranded, then you can flash any ROM you like. Just make sure there's no difference between Asian and European models (I honestly don't know either way).

This is probably a stupid question but, after debranding can you still install operator specific apps (such as Orange UK's 'Your Orange' app) from the Marketplace?

i am from algeria.
after a sucessfull flash, pin code requested.

is there a solution?

 

[pedaah]

did you have the phone pin locked before you did the update? otherwise the default is usually 0000

I'm not sure if you can cross regions - I haven't tried it - someone else here may know. Maybe try another ROM.

Hi,

Great post.

If you going to flash via the bootloader then AS or WMDC do not need to be running.

Before attempting to flash a device ensure the battery has a charge of more than 50%

It is always good practise to perform another hard reset after flashing a ROM.

Hi,

I think you will need to create a goldcard and purchase a cable (new days) or even HARD-SPL or CID (old days) to unlock your device if you want to flash ROMS from different regions, when the option becomes available for the Mozart. (if ever).

Random Apps

I downloaded and installed the rom for the unbranded mozart for europe and HATE the fact you can't select the uk keyboard... So I installed the original orange one from ansaar but it has these silly apps that I can't uninstall... anyone know how to get rid?

 

[R3PUBL1K]

As the ROM is branded then you cannot get rid of the carriers customisation, as for the keyboard, this is really no big deal, the £ key can still be used, and its not as if its a full qwerty anyway.

I have a UK Orange Mozart (Sim Locked) and unbranded to the Euro 1.28 using this method. When I connected to Zune it immediately wanted to upgrade the OS to the Pre-NoDo update but it refuses to see NoDo.

However there are reports of people flashing unbranded 7389 OS builds successfully getting the Official NoDo via Zune who are also in the UK so it's very unclear how MS are "Delivering" the updates. What do Microsoft really mean by "Open Market" ?

What isn't clear is if the unbranded phones were also sim unlocked.

I wrote this guide after flashing my girlfriend's Mozart (which was OrangeUK branded) to Euro 1.30 which was OS v7389 and as soon as the 7390NoDo update was released she was asked to update.

So, yes, I'm unsure. Perhaps they are going by OS version. But if you want NoDo, then flash 7389 (which is essentially NoDo anyway) and then you'll get updated to 7390.

Do you have to reinstall all your applications??

 

[Casey_boy]

Do you have to reinstall all your applications??

Yep. This completely reformats your phone - it's not the same as the update process. You'll lose everything - so backup your data with Zune.

That being said, you can just re-download your apps (even your paid apps).

Worked perfectly, thanks so much!

[*]Download a ROM which is by the same network as you're on (for example if you're phone is currently locked to Orange UK then download RUU_Mozart_Orange_UK_1.22.061.10_Radio_5.50.09.18_ 22.24.50.09U, by ansar. - do not download 1.30!).
[*]Open up ActiveSync/Mobile Device Center
[*]Flash this ROM to your phone (you may not need to do this step, but most users will).

• Turn your phone off.
• Put your phone into Bootloader Mode - this can be done by pressing and holding the Volume Down Key + Power Button.
• Plug your phone into your PC, hopefully a HTC USB driver will install.
• Once the driver is installed your phone should display USB mode.
• Extract the zip file and then run the exe file
  

Hopefully no-one minds me registering to ask for advice on de-branding. I have a question about the part of the procedure above where the branded ROM is first flashed. The version for my phone is here:

http://xdaforums.com/showthread.php?t=1007277

But, when I unzip that, there's no complete .exe as it's already been extracted. The unbranded ROM is an .exe which I had to extract with 7zip, though. So, what .exe should I run for the initial flash with the branded ROM (e.g. RomUpdateUtility, EnterBootloader, something else etc.)? Thanks.

Run the ROMUpdateUtility executable
