Almost fried my srt4922 during update when a sudden power cut occurred. Thank God I had RS232 cable at hand; had to flash the memory with the new patch by the help of the strong loader from wizkid.
Sorry Flybird, but one should not be worried because strong receivers can easily be brought back to life incase of premature software loadings attributed by power blackout. Another option is by inserting the software into a usb drive. Press power button and channel up button simultaneously(srt 4922), and switch ON the rear power supply switch.The usb download option will pop up on your screen and you can now easily load back your patch. Remember to press channel up button several times while holding power button for usb download menu option to appear on your screen.
