How do you connect on bench? I would use enet without DHCP. Most times BTLD is flashed over UDS. And try pinging your zgw to see if you have stable connection. You did the nbt ping? Also had one unit with same issue no way to flash over HTTP, never found the issue but unit still works. You experience same issues with other NBT? Faulty network adapter can also be an issue what I have faced once.

larshuttenin hank you very much for your support, I try to answer your questions.
I connect to my bench via OBD, in fact this thing has already happened to me with other EVO HW3.1 without GPS connector,
For the flash I used ENET and ICOM with DHCP and without
BTLD is definitely FLASH on UDS because up to 15% takes more than 20 minutes (but I interrupt)
PC network card, it seems that it works, no problem for encryption and for internet connection via LAN.
now the unit is in FLASH mode with the fan at maximum, because I have interrupted the FLASH twice.
I also pinged EVO with this CMD response
