I have Kdlinks HD720 media player and it suddently display NUPGRADE error message on power up. This play is using Realtek 1186 chipset. Reload the manufacture firmware is unable to correct the issue. After some research, it seem the NAND in the boot code were corrupted. Some people seem able to use information in this forum to fix the corruption. Since I can only understand English, I have been using google translate to help reading this forum but still not understand how the boot code can be repair. I have opened the player and connect the UART port with the USB serial TTL to laptop. By using Putty to monitor COM port, I am able to see some message at boot up and then Busybox monitor. But then I am not sure what to do next. It would be nice someone can give me some help or hint for my next step.
Thanks a lot.
Hi brother!!!
Do you fix the problem???
I was same problem with nupgrade message.
I fix with 2 files into the pendrive (remenber both files into same place)
bl12.zip
(11.13 MiB) and
full_install.zip
(1.36 KiB)
-unzip both files and put into the pen drive (clean and formated fat)
-off the player disconecting the power cord
-conect the power cord now, check dont have nothing conect to player. hd, memorys, pendrive, net cord, uart port, etc, all bays clean....
-now press the power bottom for 5 sec, when the panel show "update" release the bottom.
-put the pendrive with both files into the usb port media player.
-wait for complete install. this files will clean your bios media, and install universal boot.
-be patient, the media will restart more than 1 time.
-when the player show the old logo of realtek, was finish, and show a message, wait for update. In this moment you can install the original update, I installed HD720 v1.5.
I test and work very fine.
