[Q] No IMEI no baseband no service - Galaxy S II Q&A, Help & Troubleshooting

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 .

from the phone pad dial *#06#
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:-
Recover your IMEI in 9 steps.

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!

[Q] mobile network not available problem

I got my samsung galaxy s2 this month. Everything is ok until the day before yesterday. When I try to make a call, it says "mobile network not available". I go to the setting--->wireless and network--->mobile networks--->select/unselect use packet data, there is no icon indicator it is activate as it should be. I tried the factory data reset, but the problem is still unsolved. Thus far, call/message stop working. Wifi is OK. Do you have any suggestion on that? Thanks.
Please check your IMEI, and your Baseband version.
If they are not available, you will need to restore your EFS, if you do not have a backup, you will have to visit Samsung Service Center, or repair the EFS yourself.
Do not use another phone's copy of EFS as it is illegal to modify or clone your IMEI number in most (if not all) countries. You can however use someone's EFS backup, and mod it with your phone's IMEI if you know how to.
Hi,
I'm in this horrible situation: no baseband, no IMEI. By ny chance, do you know how to get a EFS backup and change to my IMEI?
I appreciate any help. I was trying to make a call, the person on the other side could not hear me. I reboot and...lost my baseband. Checked IMEI, it was also missing.
Thanks

have u solved your problem? I got something quite similar...
In my sad experience, your only chance is going to Samsung and ask them to restore your IMEI. From what Samsung in BRazil told me, it should be in the same country of the device. As my device was imported from the UK, Samsung Brazil could not do anything, as IMEI database is Country restricted. I believe this info is correct as the representative was very helpful. It did not look like a lame excuse. If your device is not under warranty, it should not cost you more than U$ 50. That was the price here, and everything in Brazil is so expensive these days.
My solution was to buy another Galaxy S II in Brazil as it had been released here in between the time I imported mine and the time it got screwed.
Wish you good luck.

I have the same problem, but if I take out the sim and put in another phone, it works, and if I took another sim (from another operator) and put it in sgs2, it also works, just this sim not working in this sgs2. Is this operator controlled by apple and trying to block sgs2 devices?

Thanks
I've got the same problem...
does anyone have came up with a good solution?
Try this
Root your phone.
Go to efs folder in root. Go to imei folder in that you will find a file named mps_code. Edit it using root browser from market. Erase everything and type your original imei no. and save it.
Reboot your phone and now check.
Cannot guarantee it but it worked on mine. Good luck

All I had to do to go to the Access Point Name ('APN') settings and change the Authentication Type from its default 'Not Set' to 'None'. After that, my internet is working fine.
It would appear this may be an issue common to a number of Chinese phones, so hopefully this will be of use to other people in the same situation.

[Q] No network - Samsung Galaxy S3 i9300

Hello guys,
I`ve been watching all this topics for a while cuz I have some problems with my Galaxy S3. I`ll tell you what i did.
All worked fine, had the 4.1.1 official rom + root, then i wanted to go to 4.1.2 so i flashed an UK stock ROM. After that i kept getting the "Sim has been removed" error need restart bla bla.. so i search all around for a fix.. i changed 2 SIM cards and nothing. Then I flashed a Poland version 4.1.2 Stock. That version was better but I encountered the "Call ended" error.. calls would end after 3-4mins or i could not call at all. Then i flashed (and this is when the problem started) Stock Vodafone Spain and got "No network". I must say my IMEI/ SN all are intact.
Then I patched only radio modem from the UK ROM with Odin, but with "PHONE" option (i know i did wrong).. i wanted to change only the modem and it worked cuz i checked with *#1234#.. but from that moment not even one ROM has worked in showing me the network. On About phone says "Network: Unknown". Sometimes it connects to Vodafone but when I try to call says "No network service".
Now my phone is in second service and they can`t make it get a network on. They tryed the neverlock thing but i think was already unblocked.
I tryed rooting and using this Ariza. and were 2 versions there.. I tryed v5 only and didnt worked.
I tried the ##72786# and I get the following message: Connection Problem or invalid MMI code (found somewhere that for this code i need to have Wifi on to work?)
Now i`m thinking to get my phone back and dunno reflash with a good .pit file ? or just reRoot and try v4 Ariza.. I`m really sad, it`s been 5 days and I can`t think on nothing else to do.. I even called Samsung official service and they said to send it to them.
If you have any idea, pls need help. tnx
Check your IMEI is the same as under the battery .
Samsung will reject warranty .

you are right.. IMEI and SN are not the same.. pff what to do now?
Restore your backed up EFS folder.
jje
But i think i backed up the EFS folder with the modified IMEI. What can i do now?
nothing. replace the motherboard
SOLVED!
Ok so tnx to JJEgan i checked all the IMEI numbers and only 2 of them were modified. Thing is before I pached the v5 Ariza, I did a EFS backup with that program. That backup img saved my phone.
Firstly I got my phone back from service with 4.2.1 official ROM (thats nice, cost me 0 $ ). I rooted with CF-Auto and used Ariza patch (v4). But my imei was still wrong so after that I used EFS_Backup_Restore_new_ADB.rar to restore my IMEI/SN with the old EFS backup then I used another programEFS Professional v2.0. I checked the option to repair No network and clicked Restore. After that I restarted my phone and I got the messages from provider with APN settings and so on.
Thank you for the help :good:
worked till first restart... now No network again, I`m not a samsung/android fan anymore..

[SOLVED] No network detected ????

Hey Guys;
A month ago my phone died on me. After a 1 month hassle of the company trying to dodge doing repair the phone on the warranty, they finally gave up.
They replaced the motherboard and when I got it, it gave me zero bars and no network. I took it back and they returned back with a different rom but it was working. The first was some samsung s3 in arabic version rom. The second was a chinese samsung s3 rom. Since I couldn't get arabic keyboard I decided to flash super nexus rom but now I have zero bars and no network showing.
The hardware specs are in the attachments.
Any idea how to fix it?
Stock reply
IMEI correct
Modem correct
CSC correct ??
See multiple identical posts .

Imei: unknown
Imei sv: unknown
Baseband: unknown
Can't find PDA, CSC and modem?
Looking at different posts. Tried Ariza patch didn't work. Am assuming I only need to set the imei to get a network. But what am I to set it to?

You cannot set an IMEI .
You either have a backed up EFS folder you can restore or its a service center repair .
Can't find PDA, CSC and modem? either you are clueless or its more than just IMEI is a problem .
Suggest you flash a stock rom for your area via odin from sammobile.com .
Fails then its a service centre .

I am a bit clueless, nut when I had the S3 before it died and had its motherboard replaced. I would press *#1234# to get the pda and modem and csc or you can get them in the about area. But now with the super nexus rom if i press the code it gives " no mobile network" and it does not show in the about area.
I didn't back up the EFS. This problem was present as I said before when I got it back from the in the service center they had a rooted middle east stock rom and it showed no service, they took it back, I thought the reason was loose wiring. And when I got it back it had a rooted Chinese stock rom which was able to connect to the network. The previous Original motherboard had an unrooted African stock rom, they also cheated me by giving me a 16gb motherboard instead of 32gb.
Tried to flash chinese stock rom via odin and got fail. now it will only go to download mode anything less it gives a yellow triangle.
You need a service centre but you have no warranty .

First Flashed Samsung i9300 stock rom 4.0.4 from http://samsung-s3.com/restoring-sto...ware-build-xxalf2-samsung-galaxy-s3-gt-i9300/ (I had 4.0.4 when I bought the phone.)
root the device via Framaroot 1.4.1. apk (http://forum.xda-developers.com/showthread.php?t=2130276)
Installed busybox via busyboxinstaller.apk in google play and installed busybox
last installed ARIZAPatch.apk can be found in xda developers forum and make sure you are connected to the wifi and press the V[0,5] button. Your device will reboot and there will be light.

[Q] Thought I bricked it, advice needed if possible!

I'll try and keep this simple as not to confuse anyone. Last night I thought I would have a go on a MIUI Rom [ROM] [PORT] [4.2.2] MIUI v5 3.8.29b to be exact. After the first restart I couldn't get a wireless connection through the phone so decided to flash back to stock and that is where the problems started.
First problem was the IMEI changing to 0049 etc, up till 4am trying my hardest to fix it to no avail, back up at 7:30 to have another go. I have now somehow got my original IMEI back (after finding a backup I made end of Dec '12) which I thought would cure the problem.
This is where the weird stuff happens. I have a xperia ST23i as a spare so put my 3 UK contract sim in that and was fine, put my o2 payg sim in S3 works fine, swap them back and nothing with the 3 UK sim in the S3, just no service - emergency calls only. tried manually adding APN settings but they won't save and when trying to select 3 UK for mobile network I just get 'Unable to connect, please try later' but it can't be the provider as my sim works fine in my secondary handset.
I tried installing a custom rom (Glamour S4 v2.9) again works fine with o2 but not with 3.
details are shown in 1st, 2nd & 3rd pic with other info from the status menu.
I'm also getting a black screen with yellow writing floating on my home screen? any ideas if that is part of the problem (see last pic)
Really appreciate any help given.
m also getting a black screen with yellow writing floating on my home screen? any ideas if that is part of the problem
Search factory mode .

Already done the fix for factory mode, don't think this screen has anything to do with it or does it? The factory screen was showing below this one.
Check as picture says ME7 firmware with MG2 Modem .
Why not flash the stock rom for your network .

Just waiting for it to finish downloading from Sammobile, grabbed the latest release - I9300XXEMG4_BTU, only got to wait another 50mins.
Just set everything back to stock, no root or custom recovery. Phone is still working fine with a PAYG O2 sim but nothing for my contract 3 UK sim. The rom I flashed was the latest BTU from sammobile, about devive now reads:
Android Version - 4.1.2
Baseband Version - I9300XXEMG4
Build number - JZ054K.I9300XXEMG4
Factory mode has raised it's ugly head again and still have that black box with yellow writing on home screen. IMEI hasn't changed to 0000 or 0049 so I suppose that's a bonus. Perhaps my EFS backup is corrupted? would that stop me from using my 3UK sim? Is there anyway of repairing the EFS folder without a backup. I have tried a few methods but with no joy!

[Q] Not registered to network

Hi all,
first post so be gentle with me.
OK, heres my situation... I had CM11 ROM installed, I woke up one morning to find my device wouldn't turn on, ahh just a flat battery I thought... nope, after hours of charging it just still wouldn't come up. I managed to get it into download mode and restore the ROM. In doing this it changed its IMEI to 0049... and wiped the serial number. I work in IT, so I spent hours and hours trying to fix it myself but I had to surrender and take it to a Samsung Service Centre local to me. £35 later they have restored my IMEI and serial number, awesome... I can carry on using my phone again after using a bog standard £9.99 Classic style Nokia :good:.... NOPE....
It now indicates that a SIM card is inserted, and registers to the network (EE), but I do not get mobile data connectivity!!!??? I try to dial out, but I get "Not registered to network".
My Device Status reads:
Network: Unknown
Mobile Network Type: HPSDA
Service State: Out of Service
Mobile Network State: Disconnected
This is on a stock ROM restored using Kies:
Basband Version: I9300XXUGMK6
CSC: I9300OXAGMK6
Does anyone know of a quick easy way to fix this, or do I just go back to the phone repair shop make out they haven't fixed it properly making them get it working!?
Many thanks in advance

Download a compatible firmware from sammobile and install thru odin.
Odin installation instruction should be available in youtube.
i managed to resolve this myself, by flashing a patched version of MK6.
I'll provide a link to where I found the patches shortly

This means your efs is not compatible with v2 firmware and you will have the same problem with every update in future. If you paid samsung to fix the efs then they should do it properly.
