Good Day Guys. Need some help please. When I flash official firmware for my country "N900XXUDNC1_N900OJVDNA3_XFA". Inside folder is (N900XXUDNC1_N900OJVDNA3_N900XXUDNB1_HOME.tar), I have no signal, unknown baseband and no IMEI number. I did not backup EFS. The only rom working for me is V14. So basically flashing official firmware does not fix my problem. Can you help me please.
I have the exact same problem. Did u manage to find a fix to this?
hi basically i have a note 3 which was working fine i then done a factory reset in settigs and now it says baseband UNKNOWN and imei UNKOWN
ive read up on it and says i need to flash a stock rom via odin ?
im pretty new to this and i belive the rom i need is
EVR-N9005XXUGNG1-20141015154736.zip
as im in the uk ?
i cannot download it anywhere ive tried everywhere a link or some help would be very appricated
thanks very much
Just flash a xxuene1.zip modem from recovery or flash a stock rom with xxuene1 baseband.
it worked for me.
Hi, my phone is i9505, i have null imei and unknow baseband. I
was on 5.0.1 when i buyed, my misstake i dont verify the imei if is broke or not. Imei was /01
After that i flashed 4.4.2 ([email protected] with Modem_GNK2_FULL.tar and Bootloader_GNK2.tar) in hope imei will restore but neeh...., i dont have efs folder. Now imei show me null / null.
I have any chance to get imei back to use cellular network? If YES, are you kindly to give me step by step guide with download links?
Thank you all, i`m disperated

Hi,
You might search for a modem that from your region code. If you don't know your region code, unfortunately you should go to Samsung Service Center as you didn't have any EFS backup.

Flash modem from the region where the phone was bought. Since I couldn't find the package that only contains modem, you should download a full firmware. Grab it one from SamMobile or Samsung Updates.

It really has nothing to do with a modem with your region code.
You can use any modem it really doesn't matter.
Try flashing a stock lollipop firmware.

Well, let me explain more.
1- This phone was with stock I9505XXUHOB7 5.0.1 and IMEI was / 01, after that i flash [email protected] 4.4.2
1.1- I dont know if i can come back from stock 5.0.1 to stock 4.4.2, can you tell me if i can? I was afraid and i tryed with that repack rom.
After that IMEI was null/null with unknow baseband.
2- so i flash again that stock 5.0.1 and i have IMEI null/null with a working baseband.
Advices?

Unfortunately, you both should bring your phone to Samsung Service Center for IMEI restoration.
Here is a guide for downgrading:
http://forum.xda-developers.com/galaxy-s4/general/i9505-downgrade-5-0-lollipop-to-4-4-2-t3052472
If you still can't get it back, then a guy claimed this method worked for him.

If it's still not fixed then service centre.
After i upgraded a friends I9500 to Official Lolipop , he complained about crashing apps, and other sutff like that , and he ask me to revert lolilpop to stock version . I do the downgrade with odin , i flashed a south african rom, which is allowed for downgrading , ( 4.2.2 i guess ) , everithing worked fine until the phone booted and see there`s null imei , baseband version , etc. After doing some researches, trying to flash other stock rom ( like 4.3 or 4.4 with no succes ) , flashing modem a few times , trying the method with efs backup ( even if i haven`t make any backup before downgrading ) , I get a fake imei and that`s all and still cant use the phone to make calls.
My Q is , how can i revert the original imei for I9500 ?? Need urgent help !
Thanks for your support.
Reflash lollipop modem/firmware and you get imei back.
Then you can use this if you want downgrade
