A friend asked to replace the screen on his i9300 as i've done a few before,
The phone was fine until after I fitted the screen, no signal, looked at the imei its null with baseband unknown. the phone was working before I changed the screen as he was using the phone when he come to mine to drop it of.
now ive spent three days trying to fix this phone, with no luck. being reading many threads all over the internet about upgrading
the rom etc. still the same tho.
I managed to get a cheap z3x box on line, but that cant fix this either.
here is a log from z3x
Selected model: I9300
Selected port: COM7 Z3X BOX Serial Port

any ideas will be appreciated.
Weird if just changing the screen corrupted the efs but irrespective how it happened you need a backup of the efs folder to restore. If you don't have a backup then service centre required.
If you have a box then read the dead boot thread in general forum, the later stages might work.

My GS2 suddenly got stuck in flightmode did a hard reset now shows no service!!!
has no baseband what should i do
I've not rooted my phone neither used any custom rom's please help
Thanking in anticipation
If you've not rooted your phone nor flashed any custom firmware on it, best bit of advice I can give you is send it in for warranty service. You risk losing your warranty if you try many of the 'fixes' on here.
If you do try these & they don't work, you'll end up paying to have your phone fixed, whereas now you should be able to have it fixed under warranty.
hello,
unfortunately it's past warranty period, what do you suggest now?
thanks
Since your out of warrenty then you could give this a try:-

Look for XWKF3
and download the correct firmware for your region.
Follow the instructions given on the same page to install it.
[Edit].. Power off then go into recovery first and data/factory reset before installing firmware..( 3 button combo(volume up-home-power)) to get into recovery.

Only you know why no IMEI in regards to the past firmware on your phone . Crystal ball not working today .
No baseband possibly you never flashed modem.
IMEI restore your backed up EFS no backup try factory restore .
That fails service centre .

This will give you your IMEI Number
If the number is 004999010640000
then this is the fake IMEI that is assigned to the phone if the nv_data.bin file is messed up.
Go Here:-

If its a different number
Then remove the battery and check the underside of the phone
your IMEI number is written here...Does it match!!
If stiil not working then it needs to go into the service centre
Did you flash a modem? Do it. If you don't see the baseband still try this:
Airplane mode ON. Power off, take out battery for 5 minutes. Put it back. power on. Airplane mode off.
no i"ve not flashed the modem, it's got NO iMEI
thanks all for your time.
Flashed my phone with latest Lite'ning Rom, everything is fine now.
I hope you've backed up your EFS stuff.

Could you tell me where you got your lightning ROM from and how you did it? I am facing the same problem and tried flagging xwke8 and xwkf3 but both didn't work.
Thanks,

I'm having the exact same problem..... please advice!
Hi, today I flashed the stock rom after I tried the Paranoid Android Rom, then, after the reboot, I noticed There were no Signal.
Looking for some forum, I've seen the problem should be the EFS folder corrupted.
Because I didn't backup the folder without flashing, there is a way to fix it or the only way is to bring the phone to the Samsung assistence? I think it's no more in warranty, isn't it?
What if I backup an EFS Folder from another N7100? Should it work?
I tried this guide (http://forum.xda-developers.com/showthread.php?t=2159267) but in my nv.log there isn't anything like "MD5 fail. orignal md5 'XXXXXXXXXXXXXXXXXXXXXX' computed md5 'XXXXXXXXXXXXXXXXXXXXXXXXX' (rild)
where the X's are a bunch of number and letters.".
Any Ideas?
In the home there is a window black with the words in yellow:
PDA: n7100XXDME6

and other words like rearcam/front cam

What's it?

Can be this the problem?
No two phones have the same IMEI. So, no! Restoring another IMEI won't fix.

I have the same problem with my I9100. How you fixed it? I don't have any EFS backup.
Same problem for N7100
I have spent a whole week searching for a solution for the same problem
All the posts I have seen are useless and I reached nothing
Is there a correct solution for this problem?
I have this generic IMEI for my n7100
This happened to me after receiving the OTA update for Note 2
My phone was running the official stock rom 4.1.2
I got the update OTA, installed it then afterwards I lost the network
I searched online for a solution and found out that it has something to do with the IMEI
I opened my IMEI number to find out that it is this generic number
What to do please ?
My phone is out of service for a week now
I have same problem now.
Please someone tell the solution to this problem. I dont have EFS backup.
Hi, trying to fix a Samsung Galaxy s2, cant make any calls, noticed there's no IMEI, when typing in *#06# it shows: null/null tried to use the z3x box to repair the EFS and also install the correct IMEI number its showing this information:

Just got the Z3X Box, so not really sure what I'm doing yet, any ideas on what to do would be very gratefully appreciated, I was thinking of reinstalling the firmware but not sure what to do?
Thanks

Hi,
I got this phone from a friend and I don't know the history of it but is unable to detect any SIM card and the Baseband and IMEI appear as Unknown.
Do you have any idea on how to fix it?. Thanks in advance.
i had the same problem on 850FQ i bought few days earlier.
I digged deeper into the Issue and found out when someone wants to unlock their phone it can be done by 2 ways ONE: with an unlock code which people can buy from many online sites TWO: Using some hardware device i dont know its name. The repair guy told me sometimes a phones IMEI is also changed during the unlocking process and if the process is buggy then it may also damage IMEI AND BASEBAND.
Unknown imei/baseband can also be caused by a damaged "modem chip" or it can be caused by corrupt "EFS AND MODEM" folder while flashing custom roms. But since there is no ROOT and No firmwares available for the "A" model i guess your corrupt baseband is either due to "buggy unlocking" or it is a hardware malfunction. People who have the same problem in F or other models can try restoring factory firmwares with odin (from sammobile) but the folks with "A" Model are out of luck. i sold my phone as a demo unit cus i wasn't able to recover its baseband and imei.
Try a factory reset without simcard inserted, see if the imei comes back. if not you may sell it as a demo unit or keep the device for camera and music needs
