I had to do this to my 622 today... L446 killed my Hard Drive until I re-initilized... going to archive stuff immediatly if I want to keep until I can trust it again...
anyother useful backdoor commands?
1. Menu
2. 6
3. 3
4. Info
5. Right
6. Left
7. TV/Video
8. Select
9. Front Panel Reboot
This resets NVRAM and clears:
1. Error counters and temperature readings and Lost Locks
2. OTA channels
3. Resolution to 480i default
4. Put receiver to Dual Mode default
It does NOT erase timers or check switch settings. It also does not erase recordings.
Re-initialize Hard Drive doesn't work on the 722. It just does a timer dump.
It did on mine. All recordings and settings were gone.
Time to training your fingers .
It took multiple tries to work on my 622..but it did...
