Hi all.

I was trying to downgrade my GT-I9505 to 4.2.2 jellybean using Odin. This is the complete list of messages on Odin:

<ID:0/016> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)

Now my phone is stuck in Odin mode with the message: "Firmware Upgrade encountered an issue. Please... recovery mode in Kies."

I'm using the September version of 4.2.2 firmware for Singapore downloaded from Sammobile (I cannot attach links as I'm new here)

Tried different USB ports, 2 different cables.. Just haven't tried on a different machine. Not sure if it's an issue with the firmware or what. Any help would be greatly appreciated!!

When you say "before", does it mean the stock firmware my phone came with? My phone came with 4.2 i believe, and I upgraded subsequently to 4.4.2.. Does it make any difference?

In any case, if I download 4.4.2 from sammobile and flash with odin again, it should probably be ok?

Ah thanks! got my s4 back working again.

Anyway.. my bootloader actually shows the following:

KNOX KERNAL 0X0
KNOX WARRANTY VOID 0X0
CSB-CONFIG-LSB 0X30

Seems like my warranty is still intact aye..?
