One week before its official launch, the unofficial Windows Phone 7.5 ‘Refresh’ ROM has been leaked by a senior member of XDA forums. The leaked ROM v188.8.131.5273 can be converted into a functional custom ROM and then installed on Windows Phone 7.5 ‘Mango’-based devices.
The Windows Phone 7.5 ‘Refresh’ includes a number of minor changes (the most notable is the lower RAM requirements), including MMS improvements, SIM management options, new roaming settings, and a bug fix for SMS.
The changed log for the v.3.1 custom ROM is as given below:
• Image update now functional
• Updated custom apps
• CSC file cleaned
• Removed HTC drivers
• Fixed known glitches and carried out optimization
• Pagepool set back to 3/1 MB
The last major Windows Phone ‘Refresh’ update was build v7.10.7720. After it, two small upgrades, 7.10.7740 and 7.10.8107 were released. If you wish to download the custom Windows Phone ‘Refresh’ (build v184.108.40.20673) head over to the XDA thread ROM for the Samsung Omnia 7.
