why does everytime i switch my bluetooth on there will be a message: "unable to perform bluetooth operation" although i didn't put any MMC. is there any help? anyway, my cellphone is nokia 6600. thnx.

try to restart your phone and then try switching on ur bt...

the thing that i've done:
-format via *#7370#
-restart in many times!
-now, after reformatted the phone, the camera won't work as the memory is over-load

so, what else can i do......exclude to bring it tho the Nokia Centre...
thnx again.

memory overload because u have installed too many applications on ur mmc... format ur mmc as well...

i've said that i didn't put any mmc at all. so, there wont be a problem

well u have already used a deep format on ur phone, u dont use a mmc, so i cant say anything else but the only thing u can do is to send ur phone back to the nokia care... uve already tried everything else...

why dont you try the hard format by pressing call button, star and 3 while you turn on your phone :)

is there someone know how to switch in safe mode.....holding pencil key while turn on the cellphone doesn't work...is there a "safe mode" words to tell that it works?
hashey100-that 3 buttons won't work also...already formatted the phone w/ that
way too.

the only way its going to go to safe mode if it's S60, you have to download a applacation, im not sure what it is though but ill try and look for it, it puts your phone on safe mode without a sim, ill get back.

here i found it refere to this post

The problem with your phone is actually its bluetooth device, what you can do if you have tools is to open it and remove the metal cover of the bluetooth device and reheat the chip nearest the memory card reader. Sorry if my advice sounds vague.

how to reheat the bluetooth chip?by something warm?
i'm confused....=(

Swich off ur cell phone and then open back cover then remove your battery
u'll find there Nokia Lable where Imei is printed.
Just Press Hardly as Hard As u Can near about 10 to 15 times and then turn on ur phone and check i will surley work

if ur scared to re heat it yourself just give it to a nokia carecenter 4 approxemotly £20 and they should fix it and if you have warranty just do the easy way thats my only advise :)

sohail.. are you sure that reheating will work. And why should you reheat it? I guess any heating is bad for your chips.

First step, Turn on the phone without SIM Card, then type *#2820#
If there is any hexadecimal string under bluetooth address, Your phone need to full erase before reflash.
But lf there is only blank space under BT address, replace bluetooth modul.

Do you have any box, I flash my nokia 7610 bletooth and is ok work!!!!Prodigy box

Try flash bluetooth in the phone and be all ok!!!!

I need the bt flash file for 7610. My bluetooth also dose not work after changing imei chip.

I think you can try to restart the phone, or maybe take reinstall settings

acuys to *#2820# didnt work for me.i hane nokia 6600 with 5.27 firmware which i think is the final.my phone after install a appz really friked out and i notice that my batery go s out very soon like my bluetooth is on.i check my bluetooth, is off and as i try to turn it on it show varius error messages like "btui close", "anable to perfom this action". I also have many system error, like "screensaver closed", "main closed". I also tried salih. i remove the back cover, remove the battery and press the stiker rapidly many times.The bluetooth turn on fine but after some ours same problems, same errors,
same sh**s.
Can any one pleaze help me????????:prayer:

If it's Nokia Phones(WD2), Just type *#2820# to find the BT Adress, if there's appear some kind of hexadesimal strings (for example 2f34dc6..etc), it's a softwares problem, you can fix them by software tools like UFS-Box or something else, no damaged hardware.

i think heating to bt module is the only solution . but it should be done by the professional mechanic cause overheating may damage ur bt module. if u r not sure about doing urself my advice to u is to just allow some professional to do that
