If you don’t want to wait for your carrier to push out the hotly anticipated NoDo update for your phone, you may be able to take your device’s safety into your own hands if you have a Mozart, and update it yourself. Those rapscallions at XDA have obtained the ROM file through some nefarious method, and put it up for general use. User DearMond laid out how to install the upgrade, and as ever, you do this under your own risk:
1. Download 1.09 rom from here
2. Extract the 1.09 rom to a folder, let’s name it 109
3. Download 1.30 rom (u can find the link in the first post)
4. Extract the 1.30 rom to a folder, let’s name it 130. Use WinRar to extract the 1.30 rom’s exe file – right click on the file and then look for extract entries of winrar
5. Download ModelID.zip from here
6. Extract ModelID.fig from ModelID.zip and place it into the 130 folder.
7. Reboot your Mozart Phone to Bootloader mode (Switch off then hold Vol. Down and Swith on. Release Vol Down when u see rainbow background)
8. Connect your Mozart Phone to the PC and wait for the Drivers to be installed. You should see USB written on your Phone.
9. Go to 109 Folder and start ROMUpdateUtility.exe
Go through it with next, next, etc. Let your Phone upgrade the firmware. After it gets to 100% Phone reboots to Bootloader Mode itself (and ROMUpdateUtility.exe states an error, but well, it seems this error wont bother us).
10. Go to 130 Folder and start ROMUpdateUtility.exe
Go through it with next, next, etc. Let your Phone upgrade the firmware. After it gets to 100% you are done.
What’s new on this update beyond just copy paste? Chris Walsh spotted a few changes that are up in his blog like improved Marketplace interface and searching, and others have noted there are more ringtones and improved BlueTooth functionality.
