[Q] S4 Running MH8 Baseband

hello all,
I recently went back to the stock touchwiz rom from a custom rom, & received some updates that changed my baseband to mh8.
So ive been doing some research that leads me to believe that its not possible to flash to a custom rom after the update.
So i would would like to ask if it is possible to flash a custom rom or not?
& also ive found chainsfire auto root file which i know can root MH8. But still i dont want to risk it.
Ive got a S4 LTE locked on 02 uk
Thank You

i wanted to revert back to kitkat so i flashed stock firmware from sammobile everything is working great except for imei baseband issue please help me.I already tried flashing modems.
Are u have a Backup from your imei and efs?
No brother i do'nt have anything
No solutions yet for those who wish to revert to kitkat.
But a workaround is to use the Lollipop official leaked modem with any kitkat rom.

Go To Your Phone Nd Take The Screenshots nd then post over here. If you've corrupted your IMEI then you're in a deep problem! Give me the link of 5.0.2 Russian Stock rom which you flashed.
