5: RADIOS/MODEMS

RADIO aka MODEM aka BASEBAND=Amss.bin & Mdm.bin.

The Radio Does Not Get Wiped During A Cwm/twrp Wiping Process.

The Radio Does Not Get Backed Up By Cwm/twrp Backup(nandroid) Method.

For Custom Roms The Radio Is A Seperate Flashable File Unless The Rom Dev Includes It In Their Rom.

What Ever Radio You Had Before Flashing A Rom Will Still Be Your Radio.

What Ever Radio You Had Before Restoring A Backup Will Still Be Your Radio.

Flashing A Full Stock Firmware W/Odin Will Replace Your Existing Radio (Amss.bin & Mdm.bin) And Ril/Csc Files.

Ril And Csc Files Do Get Backed Up & Restored Through Recovery.

Some Flashable Radio Zip Files Come With Ril And/or Csc Files - Since They Are Restored And As Such May Improve<>Impede Functionality Of A New and/or Existing Radio When Restoring A Backup.

Afaik Mohan_kr's Radios Do Not Include Ril/Csc Files.

Roger's radios are RAT Unlocked, which means the Network Mode in settings will work.

ATT radios are RAT Locked, Network Mode changes will have NO effect.

Flash Radio Twice W/out Cable Plugged In
​

WHAT IS RIL: A Radio Interface Layer (RIL) is a layer in an operating system which provides an interface to the hardware's radio and modem.

WHAT IS CSC: the consumer software customisation and is specific to geographical region and carriers. It contains the software packages specific to that region, carrier branding and also APN settings for data connection, MMS etc for your service provider. CSC has nothing to do with what languages the firmware supports and it will not add keyboard language support.
