Yup, you heard us correctly. Those Windows Phone 7 handsets that Nokia are making after pretty much selling their soles to Microsoft, might soon have freedom thanks to some talented hackers! Don’t get excited just yet, as there is tons of work still left to do before Android is even running on these devices but the difficult work should be nearly over, and we’ll try not to bombard you with too much technical talk!
Basically, work has begun on making the device run Linux, the system behind Android on Nokia Lumia phones with the intention of eventually running Android on them.
So far, progress has been on the Bootloader on the devices, in order to get them to work properly with Linux. Recently the progress has been on removing the protection Nokia and the chip manufacturer Qualcomn (who’s chips are inside the Nokia Lumia) place on the devices to stop you from putting other software on, however this is usually hacked through faults in their protection.
The next stage which is to replace the Bootloader which currently will only run the Windows Kernel (which Android will not run on) with another which will run the Linux kernel instead. Work has begun on porting a bootloader called LK Bootloader, however it doesn’t work properly as of yet. (You can only access fastboot, which is a method of talking to a typical Android bootloader).
After that, it will be a case of getting drivers and then building the Android system. So, full steam ahead!
