OK here's what happens inside JDFlasher. Got into Oflash, followed the following steps:

"Oflash - Flashing for Firmware/Debranding/flashing vkp etc.
1.Start JDflasher.
2.Connect phone to JDFlasher as said above.
3.Enter Oflash mode.
4.At right side, navigate to firmware location on computer.
5.Select firmware at the right side.
(I select the file 'K610_R1KG001_MAIN_GENERIC_TH_RED52.mbn')
6.Press F5.
7.Click ‘Copy’.
8.Ensure the option flash ‘as babe image' is selected. (babe for firmwares, mbn, fbn)
9.Click ‘Yeah Flash it’.
10.Wait for flashing of all blocks to complete. '

Steps 1 to 8 successfully done. But on Step 9, got this error message:
"PutFiles(putfile(putfile_flash(flashbabe(header(s end header error 19)))))".

What happens?
