My N900 does not show the USB logo and start the flashing process. I've even tried removing and reinserting the battery while holding down the u key as suggested in some other threads, but still nothing. I bought a secondhand phone (the only way I could afford the N900 I've been wanting since forever). I want to re-flash and reset the eMMC to factory defaults. I read the wiki, I downloaded the flasher-3.5 software, the *PR*.bin, and the *EMMC*.bin. I run Ubuntu, Lucid 10.04. I installed on a 32-bit machine, ran the software, got the prompt about waiting for device, plugged in the phone while holding down the u key, but the phone didn't show the USB logo,. So I tried it on my usual 64-bit machine with the --force-architecture switch. Same result. I tried holding down the u key while plugging in the USB and reinserting the battery. (Actually, two of us tried it since you need four hands for that.) The phone stays dead, and I waited up to a minute several times. So: is there any hope for me ? I should add: I don't have phone service on the N900 yet, so there's no SIM card in it. Is that perhaps causing all these problems? Thanks for any help you folks can give me!
