[Windows Phone 7 General] abhilaksh:
UPDATE 274/2012

Okay. So, Nokser's FFUPartTool extracts the IMGFS partition from the FFU.

Barin's OSBuilder (here) can be used to dump the contents of the IMGFS.

The registry files can then be edited in HVEdit (link), and the IMGFS can be recreated using OSBuilder.

FFUPartTool can then be used to replace the IMGFS partition in the FFU.

This FFU now needs a Mazaa to be flashed on. :D

If anyone out here is brave enough to flash their phone, please report the results!

UPDATE 17/4/2012

So, as we all know we have a stock mango FFU for the Mazaa (see here if you don't).

And due to recent developments, we also have this: FFUPart Tool v1.3.1

What this means is, we can create a custom FFU for the Mazaa. Now, personally, I have never created WP7 CFW before, but Nokser, the creator of the tool above assures me the creating CFW with this tool is quite possible.

So, what are you guys waiting for? Race to the finish line?

My list of things to be done starts and ends with this: get htc connection setup to run.

That's literally all we need to kickstart the Mazaa scene. Once we have that, we can do the whole shebang.

We need a ROM image for the Mazaa before anything at all can happen.

-------------------------------------------------------------

Here are the ROMs being used by people:

7.1.7649 - Test Rom. Has lots of interesting Microsoft applications (the zApps). But lacks quite a few features and stability.

7.1.7661.wp7_5_trial(mojobld).20110607-1657 - Similar Test Rom.

7.1.7720.68 - Locked bootloader. Phone is recognized as an HTC Device, but Connection Setup doesn't run.

7.1.7720.500 - Is basically the same as .68 but with an unlocked bootloader. Phone is not recognized as an HTC Device.

7.1.7740.16 - Updated via the official CAB [WP7 Cab sender tool]

7.1.8107.79 - via the official CAB [WP7 Cab Sender Tool]

7.10.8773.98 - via the official CAB [WP7 Cab Sender Tool] - 28/06/2012

Firmware revision number: 1600.1502.7720.68

Hardware revision number: 112.1410.2.0

Radio software version: 1.6.00.15.02

Radio hardware version: 8655/DDR2

Bootloader version: 7.27.00

Chip SOC version: 0.75.2.1

If anyone has different details, please post them.

-------------------------------------------------------------

The major problem with all ROMs is the lack of drivers.

1) LED lights don't function

2) SD Card slot

3) Connection Setup drivers

4) Internet Sharing doesn't work

Secondarily, because of the lack of connection setup drivers, there's no interop unlock. Which means no homebrew. Which means this device is pretty much what a technophobe buying a smartphone for the first time needs.

-------------------------------------------------------------

Does anyone know how to edit FFU (full flash update) files? They seem to be .cab files with a signed xml .blob in them.

Is there any way to edit these files?

Alternately, has anyone been successful at obtaining a stock ROM for the Mazaa? Because otherwise the device is extremely crippled.

Once we obtain a stock ROM, it's merely the point of identifying what drivers are missing, appealing to the DFT team to test the Mazaa to check whether HSPL/RSPL works, testing whether HTC Trophy drivers (and maybe other phones' drivers) work, cooking a rom, and flashing it. Once we get the ball rolling, it should all materialise.

-------------------------------------------------------------

Finally, what other problems are people having with their Mazaas?

Here's a list of problems I've noticed across the net:

Low battery life (4 - 6 hours at most).

Inability to connect to CDMA networks

Can't use HTC Connection Setup - hence no 3g/mms on certain networks

Inability to connect to certain GSM networks - lack of a valid IMEI

Frequent restarts/hangs [2 - 3 per day in some cases]

Each of these are frustrating faults.

Here' to hoping that the hundreds of DEVELOPERS with Mazaas can put in a concerted, collective effort and get this going. EVERY other phone has been unlocked/tweaked/improved upon, so why not a limited edition developer-exclusive device?
