Broken CIC stuck in bootloop
Hello, got a friend with an F10 2012 with CIC professional. Issue is the HU keeps bootlooping, shows the BMW logo and then restarts. I tried to flash it fully but it doesn't want to do it since the HU keeps restarting all the time. Any advice on how to fix it or to repair it to stop bootlooping so i can try to flash the thing? I have tools like VVDI, all kinds of programmers and some knowledge.
Any help is appreciated, thanks.

HDD is fine, tried to disconnect it, same result. Connected via esys and enet, using ZGW1, tied MOST to CIC, can see it in esys no problem but it keeps rebooting, i cant get it to be stable enough to try and flash.
EDIT: Can CIC boot without HDD or will it bootloop?
