I'll download it again and have another go.. From last time I downloaded it for this phone.. It said something along the lines of "not for tihs model" or similar.. maybe the file was corrupt via download.. downloading it again now.

Try to perform the operation with the latest Software version and post here the result.

Also, what product name is being displayed in Download Mode?

Blartiartfast · 11-10-2016, 15:12

The phone is a G935f
tried to flash another G935 and the same has happened. This is after updating to the latest octopus software. Cannot get either phone to get beyond the "system" point on any software it would seem.

Very odd. The file I used is G935FXXU1APEQ_G935FUWA1APEQ_PCT_Android_6.0.1

We've uploaded newest firmware for SM-G935F, "G935FXXU1BPJG_G935FITV1BPJ1_ITV_Android_6.0.1 ", into the Support Area. Try to write it and post here the result.

Blartiartfast · 11-11-2016, 17:06

Tried that.. Failed at the same spot. After using then oct file I downloaded from support the phone will not accept the system file. Tried half a dozen firmware files right up to an early 7 release.. all files fail at the same point.

Any ideas?

Octopus box · 11-12-2016, 08:45

Does any error appear on phone screen during write process? Are there any errors except "Dm-verity failure" in Recovery Mode?

Blartiartfast · 11-12-2016, 11:33

Sorted (by fluke I think). Used Odin and selected repartition and upadate boot.. along with a full flash.. Went straight through, and dm failure has been fixed too :-) I can go to sleep now :-)
Cheers for the help.
