Null imei baseband = unknown

[Tweakforce_LG]

I have a GT-I9505 and tried out the miui 4.4 patchrom flashed via twrp. The imei number went missing and i used odin to restore stock lollipop. Now it lists baseband unknown and IMEI null. Any fixes? I have the s/n and imei on the back of the phone

It sounds as though you have a lost or corrupt, "/efs file".

If you followed best practice when rooting or flashing ROMs and made nandroid backups prior to flashing, then you can restore that and it will replace/restore your, "/efs", file. See, #3.2 & #3.3 of [International] Rooting Galaxy S4 - Dummies Guide

Alternatively, if you use a custom recovery and made a backup in the past, most will save a copy of this all important, "/efs", file to storage on your phone somewhere.

Flashing stock from http://www.sammobile.com should fix that
