[SOLVED] Downgrade from Marshmallow to Lollipop.. NO SIM CARD error...

#Redmi_Note_3 (SnapDragon) Only..

Many user facing NO SIM CARD issue while they are moving Global Developer to Global Stable.. (Marshmallow to Lollipop)

So finally here is a Solution...

Better you should try this...

Solution:

First Flash This ROM using EDL and Then Flash MIUI7/8 Based on 5.1.

P.S. 1: Backup your data before proceeding. Use Native Backup Option under Settings to Backup.

P.S. 2: Turn off the lock before entering the EDL. Go to Settings =>> Lock screen & fingerprint =>> Screen lock & fingerprint =>> Turn off lock.

P.S. 3: Disable Your AntiVirus while flashing ROM.

P.S. 4: Uninstall previous version of Mi Flash and install the latest one from Flashing Guide link.

P.S. 5: Always select "Clean all" option in "Mi Flash" tool.

BTW I was on MIUI Global Dev 6.9.29 with locked bootloader in Redmi Note 3 (SD). And now using MIUI Global Stable 8.0.2.0 flawlessly.
