If you want to get your n900 working the quickest way by far instead of going round in circles trying to fathom out the fault is to re-flash your fw so i suggest you do that as will take no more than 20 mins to complete JOB FINISHED and n900 working. Do a backup of your device to your pc using pcsuite before you flash. Here is the link to the official Nokia guide to flashing ok. http://thenokiaguide.com/2010/01/11/...sets-all-data/ Incidently if your n900 has the leaked fw then you will have no choice but to re-flash using that fw as going back to a previous fw from that is giving many problems so dont do it, if you got version 10.2010.12-9 on your about product in the main menu then you got the leaked fw, if you got the official version of any fw then download the latest OFFICIAL fw and flash that to your device. The last official fw is the .bin file .... RX-51_2009SE_3.2010.02-8.002_PR_COMBINED_002_ARM.bin Thats the one to download and flash with. Hope this helps.
