[Android Q&A, Help & Troubleshooting] Shriji:
Hi All,

I have a Samsung Galaxy S7 - SM-G930FD - Dual sim . I received a pop up message to apply a update, however since then I've had issues.

Initially phone Displayed Android icon and Yellow warning.

Currently the Phone will not boot and the only things I can do is get into download mode, see several errors and cannot load up phone.

Download Mode shows:

====================

ODIN MODE

DOWNLOAD SPEED: FAST

PRODUCT NAME: SM-G9030F

CURRENT BINARY: SAMSUNG OFFICIAL

SYSTEM STATUS: OFFICIAL

FRP LOCK: ON

SECURE DOWNLOAD: ENABLED

WARRANTY VOID: 0(0X0000)

AP SWREV: B:7 K:5 S: 6

======================

-Sometimes Phone displays: An error has occurred while updating the device software. Use the Emergency recovery function in the Smart PC software.

-Occasionally it displayed following Erasing (blue screen with Android icon), Installing system update (blue screen with Android icon) and then the 3rd screen goes to

=============================================

#Reboot recovery cause is [unknown]#

=========================================

The steps I've taken so far is:

-Tried to clear cache however I am no longer able to do this any more...

-Downloaded Odin3 v3.14

-Downloaded firmware from Sam mobile ...galaxy-s7/firmware/SM-G930FD/INS/download/G930FXXU7ETA9/323883

-Put phone in boot mode, loaded Odin .........once Odin said added and 0 : [COM7] in blue selected the BL, AP, CP & Home_CSC & clicked start (left all options as default in Odin)

it carries out steps until param.bin and eventually fails 5-10mins later.

I tried with just the CSC instead of Home_CSC...however does not pass.

I've charged my mobile with mains connection, however phone does not have any red indication light, however when I plug phone to PC I'm able to leave phone in Download mode for a long period of time with blue screen on.

I've also tried the SM-G930F firmware (from Sammobile) as though as my ODIN Download screen does not mention D at the end of SM-G930F it may be wrong version, however sticker on the back of phone indicates SM-G930FD...

I've also tried downloading SmartSwitchPC_Setup.exe, however once installed it says my device is not compatible.

I've also tried 2 other genuine Samsung cables and tried this on another PC, but this does not seem to work.

Please could someone help resolve?
