I bought a Snapdragon 800 MDP from ebay.The seller mislead me stating "It's perfectly functioning" but later I discovered ,it has 0 imei number and "unknown base band".I can't access Play store and connect to mobile network.Other than that the tablet is functioning normally.
Previous user has tried to install a incompatible custom rom.I think restoring the factory default firmware will solve the problem.
I don't like to return the MDP as everything else is working perfectly.
So can anyone has the same device upload a rom backup which i can restore to my device?
Any advice is also highly appreciated.

It says " MEID = 00000000"
On settings > device status,
MEID = 00000000
IMEI = 0
Baseband = unknown.
It detects the sim card and shows the network name but does not show signal strength and can't connect to the mobile network.
Thanks

There is a serial number under the battery as well as the phone IMEI.
Look under the battery and look on the box. The barcode under the IMEI number has some numbers under it, that is your device serial number.
Thanks, under the battery there it says S/N and then there is a number.. is it safe to assume that this is the serial number?
Note that this is different to the number on the barcode on the box
Yes, S/N stands for serial number

Could I just ask how many digits (decimal or hexadecimal) the serial number is...?
(I won't bother trying to explain why I'm wondering)
Isn't the IMEI-no. the serial number?

thnx brother
Serial number not vaild...?
I'm trying to do this in Kies and am having no luck. I've tried the following:
IMEI + Model Name
S/N + Model Name
IMEI + 2 digit IMMEISV + Model Name
I've entered pretty much every number I can find on the box. When I enter the S/N and Model Name (SGH-i777) I get a weird character message
What am I missing here?

"wierd" as 00195ef068dfae -this is what my phone shows for S/N under Settings/About. But this is another baseband/imei stuff problem.
And the actuall SN (under the battery) is ofc not showing! And the box only shows IMEI + Barcode + color
I don't know if this is right, true or works, but from a IMEI blacklist checking site i discovered that the the imei contains the following :
TAC: XXXXXX FAC: XX SNR: 580206 CD: 3, so if someone can confirm that these SNR: digits are actually the SN of phone than you solve it. Cheers mate.
Same as me..not same as in the back of the phone afer flash stock firm from sammy

This is not I9305 forum .
Restore your EFS backup /

I have recently bought a fake Note 4, but it did not work on T-Mobile, so I tried to flash a radio image to it.
The problem is the radio does NOT work,the symptoms are:
1.) Mobile network type = UNKNOWN:0
2.) Service state = Radio off
3.) Mobile network state = Disconnected
4.) IMEI = Unknown
5.) IMEI SV = Unknown
6.) Serial number = 0123456789ABCDEF
I think the device has a MediaTek MT6582(faked to look like a MT6592) processor, and it has android 4.2.2(it is faked to look like 4.4 though).
It has NO recovery, when I boot into the recovery I just get some china BS, Testing, Factory reset, and version info(which doesn't work).
I have already tried putting in a new modem.img that did not do anything
A search of the build.prop says it is a sangfei82_we_jb5 device, I can't find any information on such device.
It also says it is a ALPS.JB5.MP with a MP version 1.000
I do not have any backups or files for it(which was very dumb I know).
MTK Engineering mode does not change IMEI or send AT commands.
Is there any way I can get it to working order so I can make phone calls?
BTW the WiFi and Bluetooth are both still working.
Hey there!
From one day to another my phone stopped working. I did NOT modified in any way, always used offical firmwires.
It says only emergency calls, and when i call someone it says "not registered on network".
I did soft reset/hard reset and also firmwire update, no success. Tried every single soultion in settings (setting only GSM ect ect).
It can
-see the sim card (others too, also sims are working fine in other phones)
-has signal all the time
-see every other phone network (when i try to choose any it says the same "not registered on network" message)
-IMEI and SN number exist not empty or null
I bought it from a supermarket years ago out of the box, factory SIM free, not reported stolen, have my IMEI number when i type *#06#, BUT when i enter the service mode (*#0011#) it says:
CS: reg_denied
MM state: nocellavailabe
PS: reg_denied
GMM state: GMM_noservice
IMEI CERT: FAIL
Support net block : 1
What can be the problem and how could i fix without taking it to a service shop? Any idea/post appreciated.
got a similar problem . i can't register on network and on 0011 i get:
CS: reg_denied
MM state: Attempting ToUpdate
PS: reg_denied
GMM state: LimitedService
IMEI CERT: PASS

Sent it to Samsung service and they repleaced the motherboard and a few other stuff, but the main problem was that. I have no other info about this issue, working since then.
What about the IMEI?

IMEI number, other serial numbers pretty much stayed the same, never lost them. The only thing changed is the date of manufactoring since it has a new motherboard. It was free tho, I managed to get extended warranty, motherboard + service charge overall can go up to 100-150€ /don't take it as a fact/.
Service mode looks this now:
CS: reg_roam (roaming at the moment since on holiday)
MM state: NormalSrv
PS: reg_roam
GMM state: Registered
IMEI CERT: PASS

Hi , first your device is x552 model not x522 but never mind .
In order to fix imei you need to flash nvram.bin and you need to allow in scatter file nvram.bin to be flashed.
First download this firmware:
https://www.4shared.com/get/H9yvkOUoce/MT6795__Infinix__Infinix-X552_.html
Once you download , extract on Desktop , make new folder on Desktop and put just MT6795_Android_scatter.txt and nvram.bin which you can find in Extra files folder.
Now in order to flash nvram.bin you need to edit scatter file and enable instaling that file .
Here you have easy video instruction to follow:

If you solve the problem , edit this post as SOLVED!
Good Luck
Any One suffering from same problem, Below are Easy steps to fix Unknown Baseband version, NULL or Invalid IMEI and SIM cards / Network signal not detected on a Mediatek Android phone.
Before you proceed, ensure that your Mediatek phone has a valid Baseband (not NULL Baseband). If your Baseband is unknown then download the firmware for your model and flash using SP Flash Tool . Flashing the firmware to restore Baseband. With Baseband regained, you can then proceed with fixing IMEI.
You can use below mentioned tool to ENter EMEI again, But your mobile should show a valid baseband version or the below tools will not work.
SN Write Tool (SN Writer) method
Maui META method.
