Ok so here is the easiest way.use factory service mode with e3 card reader,if you don't have e3 card reader download ps3 factory service mode tool 0.2 for cex console.and than download lv2diag.self file 1 and 2 .download these files and follow the tutorial.and if you are thinking it will stuck in factory service mode.than your wrong.

1:Install the factory service mode tool 0.2
2:drag ps3updat.pup of rogero 3.55 v3.7 and lv2diag.self (file 1) in the root of a USB flash drive
3:plug USB in last port of USB near bd drive.
4:run the software in ps3
5:don't panic because of black screen it's normal.wait for near 5-10 min
6:your ps3 will shutdown and than take USB out and delete everything inside it.
7:drag lv2diag.self (file 2) in the USB flash drive.
8:plug in the ps3's last port near bd drive.and than turn it on.
