Fix the unknow baseband, no signal with ROMS

Hi
I have a droid 3 with Verizon Stock Rom and with the Radio of the XT883.China. When i flash the phone to any ICS or other ROM the baseband appear as Unknow, no Sigal, no IMEI, etc.
Before to flash to any other rom you have to flash the original XT862 radio and then flash to any rom that you want.
This is my problem and how i fixed.
I hope that this solution help to other users with this problem.
If you want the original radio tell me and i put in the post.

My device is Brazil 1802 USA - Could i flash Indian Stock Firmware ?

My device is 1802 firmware USA - BR
Could i flash Indian firmware stock, or will brick ?
I think if yes, its solve my problem, when i try flash oreo custom roms.
I lose IMEI ever, if i flash stock indian, and put custom oreo, baseband is the same, my IMEI remains...all right ?
Or brick ?
PS: this method persist.zip not ok for me, he make me lose IMEI when i put oreo, so, not want more this method.
Thanks for attention.

Uknown Baseband - Can't downgrade modem to repair IMEI

I'm using a Galaxy M20 (m205f). Trying to root it, I somehow messed up the radio and efs partitions. Tried to install the latest stock Rom and it updated the binary from U4 to U7 with a null IMEI and unknown baseband. The IMEI repair softwares need the modem and the modem version presently is of U7 binary which is pretty recent and no IMEI repair tool supports this modem version yet. Is there any way I can downgrade the modem? There's no lower Android version and no combination file for the U7 binary on the internet so I'm stuck. Can I somehow put an older CP/Modem (from lower binaries) and make it work with the latest firmware?
