No OS installed, stock recovery OnePlus 2 I was trying to restore my Oneplus two to stock it failed. using the toolbox allowed me flash and boot into stock recovery. 

From here, I've tried sideloading the stock Rom which completes but won't actually boot. Flashing TWRP also returns an "okay" but I cant actually boot into TWRP recovery.
There is no OS installed.


I can get into stock recovery
I can get into fastboot
I can get into qualcomm mode
Bootloader is unlocked
I can't boot into custom recovery
I can't boot into system after sideloading "success"


Can anyone help me? Thanks in advance.
I'm so stupid, I had not placed the files within the platform-tools folder, that did the trick. the system.img was too big to be flashed directly and needed to be compressed into several sparse files, performing the operation withing platform-tools will do this automatically.
