Flashtool 0.9.23.2 error (have googled intensively b4 posting)

[PereAzzrael]

hello everyone

device is SGP712 (unlocked bootloader , LineageOS 7.1.2 )
Flashtool is 0.9.23.2 (runing on linux debian)

sudo flashtool correctly sees the device connecting in either fastboot or flash mode. (no issues there , or so it seems)

objective: flash an ftf file made from an xperifirm download. (to revert to stock rom)

I select flashmode, then browse to the made ftf , I do not check any choice in wipe/exclude

leave the buffer at its default 512K

click on flash.

I get these two errors:

ERROR - (X10flash.java:735) - null
ERROR - (X10flash.java:736) - Error flashing. Aborted

(tried different ftf , same error)

activated DEBUG logging and i see the repetition of this patern:

DEBUG - (USBFlashLinux.java:57) - OUT : CommandID : 9 / Flags : false,true,false / Data length : 1 / Data CRC32 : EE 0E 61 2C
DEBUG - (USBFlashLinux.java:75) - Reading packet from phone
DEBUG - (USBFlashLinux.java:81) - IN : CommandID : 9 / Flags : false,false,false / Data length : 0 / Data CRC32 : 00 00 00 00

with each commandID the out is false,true,false and the in is false,false,false
data crc out is always different then data crc in

here is a pruned DEBUG log at the following url (can't post url as i'm rather new here)

anyhelp would be much appreciated.
