Disable the channel can be done by setting the channel bit to 0. When you flip the channel will jump
Enable the bit does not gurantee the channel can be enabled. It depends on if this channel is available in your area.
Here is how you search for it.Backup your NVRAM first.
Code: Select all
Search the NVRAM range from 00 01 02 00 between $20b000 - $20b1d6
Here is what I have
00 01 02 00 81 9F 00 10 FF FF at address
Use 5th and 6th byte is 0x819f. Sub 0x8000 got 0x19f.
Use 0x19f * 0x20 = 0x33e0
Add 0x200418, 0x200418 + 0x33e0 = 0x2037f8
Go to address 0x2037f8
Offset 37F8 size 200
7F FF FF FF FF FF FF FF FF BB FF 7F FF FF FF BE
FF D6 03 FF FF FF FF FF 01 60 00 87 FE 00 00 7E
C0 00 00 00 00 07 F0 00 00 00 00 00 00 00 00 00
Each bit in here is a channel enable/disable. So try to disbale one channel just reset that bit.
Change the first 7F FF FF to 7F 00 00 to see what happened.
