Patches to use

Target area	Patchfile	NAND Offset	Paste length	Remarks
ROS0	patch1 (7 MB)	0x0C0030	0x6FFFE0	CoreOS (prepatched 3.55)
ROS1	patch1 (7 MB)	0x7C0020	0x6FFFE0	CoreOS (SAME as ros0)

PUP to use

Rogero V2 or any firmware with prepatched lv1 (no syscon hash checks)

Different Factory Service Mode SELFs

For factory Service Mode install:

• if using the normal lv2diag : Use a NoBD patched PUP (e.g. Rogero NoBD PUP) (to prevent error 0x8002f057)
• if using the jaicrab NoBD lv2diag : Use the Rogero normal PUP
