Otg cable is useful if it lets you enter into recovery... If it does, do the following steps:
1- FROM PC:
Download the rom you wanna flash (for d800), better if it isn't heavy, maybe download one of the aosp rom (300 mb max);
When the download ends, take a usb pen, connect it into the pc, then move the rom in the usb.
2- FROM THE PHONE:
Enter recovery mode (search how on google, its really easy);
Once you're into recovery, connect the otg cable with the usb pen you used before;
If you are on TWRP, go to "mount", and select OTG, if you are on Philz's, ignore that;
Make a simple wipe (wipe to factory reset----> data, cache, dalvik);
Then, flash the rom you have in the usb pen by otg cable.
Ok, once the flash ends, BEFORE REBOOT, DISCONNECT THE USB OTG CABLE, then reboot...
Try this way, if it doesn't work, tell me
