I solved the issue. I disconnected my router from the internet but kept my ps3 connect to the router then i uninstalled the update files and then it started.
Apparently if you put in the disc and download the update without starting the game with no internet connection prior to doing the update...
I tried it with REBUG mode Normal mode, Cobra on, Cobra off, with Internet connection and without internet connection but I always get the same Results.
My PS3 is a CECHH so a fat ps3 with NOR flash
NFS Rivals, NFS The Run, and Rayman Legends work like a charm but when I start GTA V th screen goes off, then goes on for a sec, goes off again and the turns on again and loads XMB.
The disk works perfectly on a second system.
Today I tried to install GTA V again on my PS3 but when it finally downloaded all the updates for the game and I tried to start it, it just kicked me back to the XMB. I have a a Physical copy of the game and I installed it from the disc and also have the disc in my PS3 when starting.
I tried...
I can't get WIFI to work and the Bluetooth manager can't fins any devices, i tried BT 1.0, BT 2.0, BT 4.0 and BT 5.2 devices none of them get recognized. I have a CECHH model (the first model with NOR flash)
