Re: N900 Problem: SIM Card Not Recognized
 

I meant that I was going to reflash the internal memory card to factory settings. I thought that maybe something I installed somewhere along the way was messing with things (though I never installed anything from extra-devel or -testing) so I wanted to start completely from scratch.

So...I reflashed both the eMMC and the firmware, and nothing changed for the better. The way I know something is still wrong is that 100% of the time, whenever I'm able to establish an EDGE or 3G data connection, within 10 minutes (usually within even just 1 minute), I get the "no SIM card inserted" error.

Guess it's time to give up and call Nokia.. :\

Guess I'll go ahead call them up as well. Let me know what they tell you. I'll post what they tell me as well later this week when I call.

Re: N900 Problem: SIM Card Not Recognized
 

mines started doing this aswell just today:mad:. really peed me off coz i flashed it like 5 times with the uk version. then i ended up doing a global flash and it seemed to work fine try using the other versions. hope this helps :)
btw first i did a emmc flash after that was complete i switched on my device then switched it off, then done the global flash

Re: N900 Problem: SIM Card Not Recognized
 

I had the "no sim card" problem last week, my n900 was working great, but i wanted to flash and start fresh, what happend was i flashed my n900 that was running PR 1.1 with the earlyer firmware then i got the sim problem, then i flashed with the PR 1.1 global and everything was fine again (phewww), no sim probs etc , i did however sh*t myself at the time lol, thought id ruined my n900.

Re: N900 Problem: SIM Card Not Recognized
 

Ok so it worked by going global on the firmware. I can do that and it will probably solve our "no sim" problem but for how long? The real question is: Why do some of us have this problem and some of us dont? My wife and I have the same firmwares installed and she doesn't have that problem at all. Here is the difference:

My wife has never done any downloading of apps of any kind, her phone is like brand new. I'm the one who enabled all the repositories on my phone and downloaded apps. Only thing I downloaded from extras-devel is MSN Haze. Other than that, everything else is from Maemo Extras and Ovi Store. I'm assuming it's an app that is causing this problem yet I don't know which one.

You guys aren't experiencing that sim problem after flashing because maybe whatever app it was causing that problem is no longer on your phone. I don't know this is my assumption for now lol.

my phone was likre new aswell i downloaded no apps all i did was switchoff and switch on and itg stopped reconising it might just be a random fault that occurs

Re: N900 Problem: SIM Card Not Recognized
 

ive now got this 'sim not recognised' problem, flashed with:

RX-51_2009SE_1.2009.42-11.203.2_PR_COMBINED_203_ARM

i was on pr1.1 before

is there a solution yet?

Re: N900 Problem: SIM Card Not Recognized
 

Yes, update to 51-1 (over WLAN or via flasher). The PR1.1 update also updated the firmware for the GSM hardware, and it's no longer compatible with earlier firmware versions.

Re: N900 Problem: SIM Card Not Recognized
 

To confirm what Rob1n is saying, I also had this problem and reflashing to PR1.1 resolved it...

Re: N900 Problem: SIM Card Not Recognized
