Hi to all,


Update on 17.02.2013, WP8 LEO ROM development

I am developing a new WP8 ROM for LEO and can access all WP8 STORE apps

as HTC apps, apps, games, music and podcasts, under the name of MARKETPLACE

Up to now all music and podcasts work ok but for HTC apps, apps and games

there is a pop up of comparibility warning as can be seen in the following screen shots

In the ROM are also included all WP8 lock screens, wallpapers and sounds, and more items

I hope to develop this LEO ROM as further as posible

How to extract? OSBuilder?
Click to expand...
Click to collapse

no, you can't use osbuilder because this rom isn't built like other winCE's roms (wm6.x, wp7). This rom has got his own filesystem (I think it should be ReFS), and his own structure. You have to wait because some developers are digging into it. Right now we only know that the system structure is similar to a Windows PC, even drivers are in sys format (this is a bad news for those who are waiting a porting to older devices).

I know what's exactly in it! It has 2 user profiles (default & public), a windows folder + system32 folder. And *.sys drivers.

(I don't know how, but I have a dump!)

I've linked diamondback/flemmard n other deva to this thread, as you're not the only ones with this problem, android is updates HTC are using the same method

So as you can see this isn't specifically windows related

A few tidbits that might help you guys further. WP8 kernel overview can be found here: Windows Phone 8 Kernel Architecture

It seems to differ also from W8 with that way that the user mode driver model is not supported, just KMDF & WDM kernel mode drivers. Packages are developed by installing The Windows Driver Kit (WDK) and top of that couple of specific WP8 kits. There is user mode only for applications which the OEM installs.

Sorry, it's not much, but that's all info that has floated my way..

it is not differ . its WOA ( windows on arm ) with some additions ( becose its a phone lol )

1. codebase of gui is shared with 7.8 - you really thought they will rewrite it? becose of it and becose Its a phone where you dont need explorer.exe subsystem. some additions was made into os composition . its more similar to - windows embended then windows RT (WOA ) . biggest example of embended roots is - Image update process . in WP8 system partition with main os - read only ntfs . in order to write something there - system reboots into Windows PE enviroment.. rest of the system is damn similar . even SXS in place lol . ( atleast package structures clearly indicates on that ).

2. disabling kernel mode for all apps is expectable . in early 2012 they sayd. that they did it to minimise of potential security impact in bugged OEM SOFTWARE . or you really think - they does not noticed security hole in HTC connection manager or some OEM software which helps in jailbreak os .. ofc they know it

can anyone give me a link to the ROM. I've been looking for a link but all seem either dead, or the ROM is damaged and cant extract the nbh properly.

it's very interesting to see a "non compatible phone" from WP7 running WP8, clearly Microsoft lied to us in the face about the upgrade process to jump from winphone7 to winphone8.

    no, you can't use osbuilder because this rom isn't built like other winCE's roms (wm6.x, wp7). This rom has got his own filesystem (I think it should be ReFS), and his own structure. You have to wait because some developers are digging into it. Right now we only know that the system structure is similar to a Windows PC, even drivers are in sys format (this is a bad news for those who are waiting a porting to older devices).

    Main partitions are always NTFS
