[Q] Help me my phone problem

My phone status show phone:unknow ,and can't search SIM card.

Try factory resetting. If that doesnt work. You have to flash a new rom
Edit: What did you do first before that happened?

@ skinarg, just a note: I checked the site and got a warning from avast. it only happened once, and I investigated and found no real threat. just be careful, just in case
that's good news for those unable to recover their imei any other way

HELP! xperia j invalid sim card

PLEASE HELP!
I don't know what really happened but I had installed cm10 on it and then I see no service
I've searched on forum and was adviced to flash stock ftf but nothing
when booted the phone asks for sim pin "whats means that it reads the sim card" but after insert the right pin
the phone shows "invalid sim card" and got no service
I've did many times and still the same problem
before I get the phone my girlfriend had tried to partitioning an sdcard with minitool partition wizard
but she did it with the sd inserted on the device
maybe that was the cause the problem
please help me

Thanks for your help bro but even when I flash stock ics i can't get sim to work
If i just flash only the stock ics i get invalid sim card
And when i install cm10 over it the problem is still there

try these:
--> remove sim card and place it again correctly (works sometimes)
--> when you enter the CWM make sure you completely wipe your data includes- wipe cache, wipe /system, wipe dalvik cache, format /data /cache and then click on reboot the system now and remove the battery. go back to flashboot mode and flash the ICS firmware and i hope this might help coz this is what i did to my phone

Nothing bro! still the same
my phone asks for the sim password "PIN" and it only accepts the right pin code, what means that the phone reads the sim card
but i don't know why there's no signal and appears the message "invalid sim card"
I've tested many different sim cards and nothing solves
if I did something wrong
theoretically I just need to reflash an stock ftf and everything should be ok
but that doesn't solve the problem

it is because of trim area damage
you should have backup your trim area before unlocking bootloader
trim area, google it
and read about it
good luck

[Q] Help!! IMEI NOT WORKING

Hello all,
I have a KArbonn A2 phone with gingerbread.... i tried flashing the ICS firmware of KArbonn A2+ since i knew both phone have exact hardware with no change at all. After flashing ICS it was runing all good and smooth but the only problem is i couldnt get the network on it. It shows the SIM name
but always NO SERVICE .. i flashed back to original now but is there any tweaks to make network work on ICS?? It would be great if all those users like get to upgrade to ICS since it is one of the most cheapest android phone. Thanks

net work not working
mybe you can try this:
press *#*#4636#*#* and then. choose the right model.
if you have GSM sim card so just switch to gsm if not switch all.

Your issue is that your efs partition got corrupted and this can only be fixed by the OEM legally. I would send it in for repair.

Your problem is that when you are flashing a new rom your imei number is getting deleted and hence you are not able to connect to any network. You have to take backup of your imei before flashing a new rom. You should check this link out

Its inside the ftf file, u can see it while you flash it in flashtool on the right side box named exclude.
While you flash be sure to to tick all options except baseband.

i have tried that but still i don't see any option for BASEBAND in the exclude section. and apart from having NO SERVICE problem, my phone seems to be stuck in AIRPLANE MODE. WHen i tried making calls, it says please turn off airplane more. In settings->about phone->status->service state-> Voice: radio off / Data: radio off. Did u have the same issues?

i've tried all the above but it still doesn't work. i guess the phone is faulty and i have returned it for a refund.

I changed the main LCD Flex Cable on Z3 (D6603 model), and the phone started to read IMEI and see Sim Card. As I see, this flex cable also connects antenna module with mainboard. I know it is very late reply, but it can be useful for somebody else.

Install it again and see if it works, maybe some files corrupted during the installation.

What software did you have before you tried to flash it (give exact description).

I threw it in the trash
I bought a new S8 device

It's a kind of show off.

ALWAYS backup your EFS folder, no matter what phone u have., and then save it on ur PC.
