I have two 920 s that I had to master reset on after I converted them to Hits. Originally they seemed to work fine , but after a while they both locked up and corrupted their maps
while changing channels. On the first I was still on X4 and on the Second I was on SES 1 (W4 or G4..forget which). I believe the corrupted maps were because I still had X4 in the maps WHEN I did the authorisation and the channel count went over 4800. After a while this caused the recievers to lock up and lose the maps.
CAUTION ; A master reset on a 920 Will ERASE all the Generic Satellites. They are not reloaded from HITS, and you will not be able to tune DC channels on any Sats after the MR , other than X4 , G0, G5, G9, C3, G1, C4. 922 models had the generics in firmware, 920s did not. Unless motorola restores the 4060 stream and puts the channel maps back up these two receivers will be stuck with just those tiles for any digicipher programming. After the MR sat G9 will be available. After the remap from Hits sats for G0,X0, X4 will be added to the 21 sats available after the MR. I beleive ONLY G9 has DC channels in the correct symbol rates after doing an MR on a 920.
At any rate The maps for hits WILL reload from X4. However to get them to load you must be on the right location (103W) and use sat G9-1, verify the frequency and V polarity and then tune manually. After doing that the Hits maps will load. You then have to authorise and subscribe to them via SRL or Skyvision.
