After you have flash a correct rom but could not make a call due to invalid imei, One can follow these steps
First of all get a custom recovery for the brand of phone (twrp /Cwrm) and flash it into the phone using spflash tool(lastest ver.5.17...).After that using the custom recovery, flash in super su(zip)Then download tool hero apk (formally mobile uncle)
Open tool Hero grant it superuser access, look for imei, click on it, you can then recover or modify your imei
You can connect your phone via Wi-Fi hot-spot with any phone nearby as you use tool hero apk... good luck!!!
