EVA-L19 /cust "Invalid argument" BRICKED

[bstonge]

Hello,

I have an issue with a P9 that I'm hoping has a work around. As of now there is no rom on it because I am unable to install one. Before this happened I updated to the Nougat 7.0 with the emui 5.0. I flashed the wrong version so I attempted to wipe and reinstall stock to no avail.

I have access to recovery between stock and TWRP. The bootloader is unlocked. I have attempted to flash stock with the dload method but always gets stuck on 5% and fails. When I try to flash with TWRP I get the cust "invalid argument" error. I have attempted to extract the files from the update.app and flash with fastboot but when I get to cust.img I get an error:

C:\platform-tools>fastboot flash cust cust.img
target reported max download size of 471859200 bytes
sending 'cust' (257481 KB)...
OKAY [ 8.301s]
writing 'cust'...
FAILED (remote: partition error)
finished. total time: 8.316s

I tried this method of restoring the cust partition and I receive an d error saying that there is not enough space.

My last resort was to attempt to wipe the cust partition but I receive "command not allowed"

At this point I'm unsure what else to do. Does anyone have any other ideas on how to restore the cust partition?

Just though I'd let you know that this was a newbie mistake.... For future reference, When you attempt the dlaod method DISCONNECT the usb from the computer or it will either hang or fail. My phone is back up and running )
