To create a retail NAND image from RGH files, you need a clean SMC, an unmodified KV from *that* console, the CPU key, the correct CB value and LDV.

Boot to XeLL and post the fuse values and upload a copy of the NAND image somewhere along with the CPU key.

It's been a long time since I've done this, but I may be able to create a retail NAND image for you to try.

Thank you BL4K3Y
I appreciate your help. But owner decided to take console back.
But there is nobody in my area capable of this. So he will probably comes back.
If I decide to try by myself, do I need to increment LDV?
I never had to Create retail nand, but I remember there are some good guides here.
Thank you anyways. If he comes back, I will contact you.

The CB and LDV need to match what CPU fuses expect or the console will not boot in a retail state (fuse checks are revoked in JTAG/glitch kernels).

The "F" count on fuse line 2 tells you what CB version to use and the "F" count on fuse lines 7 and 8 tells you what LDV to use.

Be warned though that if you have made any changes to the KV (modified the DVD key or console region for example) without first backing it up, your console will not boot in a retail state, even with the correct fuse values.
