Twice in my practice I had the same problem with HiKey960 boards (update: those problems could be finally resolved).
The prebuild Linux images were downloaded from (http://builds.96boards.org/snapshots/reference-platform/openembedded/morty/hikey960/rpb/latest/) and then flashed to HiKey960 with following commands (UEFI was also updated before):
fastboot flash boot boot*.img
fastboot flash system rpb*.img
During update the images were transferred significantly slower than before (nevertheless, via UART I could see that bytes were transferred).
After the flash, I switched the board in the normal mode and I got the following log:
[details=Normal boot log]hikey960 boarid:5301 xloader use UART6
scsysstat_value[0].
clear reset source

secdbg not DCU.

xloader chipid is: 0x36600110, start at 396ms.

ERROR: Failed to load BL2 firmware.[/details]
So BL2 firmware could not be loaded.
Then I went into the recovery mode (using the switch). In the recovery mode I execute command:
./hikey_idt -c ./config -p /dev/ttyUSB1
The command seems to work correctly (see the following log obtained via UART6)!

The chipset could successfully enter fastboot mode (after flashing recovery files).
In recovery mode the fastboot seems working fine, but the ptable update does not work:

I had a feeling that the EMMC or UFS are corrupted, but I don’t know how to check it.
Update 1: I have also tried to use script from https://github.com/96boards-hikey/tools-images-hikey960/blob/master/install-prebuilt-uefi/hikey960-efi-prebuilt.sh (-d -v 38 options) and I got the same Synchronous Exception.
Update 2: Finally, I could recover the flashing. To do this, I had to replace l-loader.bin with the sec_fastboot.img available in the https://github.com/96boards-hikey/tools-images-hikey960
