Hello Scorpius,
do you think that this could work also from bluestacks on pc?
it's possible to root bluestacks since a long time. That would save me a lot of time in trying to install nitdroid on the N900.
Is the different imei between the two devices still a problem even nowadays that the password algorithm as been completely changed?
If it woks I could then try to register my number on bluestacks, block my contacts from official whatsapp in bluestacks, and then look for the XML configuration file and copy its password to yappari.
Thank you in advance for your patience,
Luca
