So you've got to give me a tough one. ()
Hi VOS. I have one of my HR20 DVRs constantly rebooting since the install of the new software (0x57b). Before I attempt to call directv, do you have any advice on what to try? Thanks.
These haven't been made in over 4 years.
Some have had power supplies go bad.
The couple of things to try:
Pull the power cord for a good 10 min and see what [if anything] happens when it boots back up.
When it does boot at the "running receiver self test" screen press select to enter the diagnostic menu and run the guided test to see if there are any errors.
If none of this shows anything, "you might see" if forcing the old software does.
At the first "Hello screen" press 02468 and it should change to searching for new software, and during the day, find the old Blue GUI. If it does "fix" the rebooting, it may not last because the new GUI will be pushed to you again, so this DVR may need to be replaced.
