recently i bought a new nokia n900. i make a home ad-hoc wifi network and connected to it. 2 days it worked normal. after started not to connect to ad-hoc. i update it by OVI-suit. it started to work. but 1 day.after i read from maemo forums that full hard reset will solve. i downloaded RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin and RX-51_2009SE_20.2010.36-2.003_PR_COMBINED_003_ARM.bin . i flash nokia with maemo flasher. after it connected once...and don`t connect . i notice that bluetooth won`t work. there was no BT address. no factori name. and when i want to save it won`t save. i send it to warrenty service. they said that if i did it with flasher warrenty service is out!!!. i leave it to them to solve problem for money. a 25 days they they coulden`t solve the problem. please help me . the DMesg reports: "w11251: ERROR timeout waiting for the hardware to complete initialization".
Sorry for bad english.

I do not know how to solve this but in my opinion if problem is not solved here,you must go to nokia care center and presuries them to solve this issue as it is looking a hardware fault!(because you have already flash your EMMC and the firmware)
As far as maemo flasher is concern i think it is not illegal to flash and does not harm your warranty!( i may be wrong)

Any other idies?
