ReadyNAS RN516 stuck on boot after FW upgrade
Hi!
I'm an experienced ReadyNAS user with 10 years and 3 different models in history. My current NAS is an RN516 with four WD RED 6tb NAS drives.
Last week, after checkin everything was ok and no errors were found, I started a routine FW upgrade (6.5.0 -> 6.5.1 or 6.5.2; can't remember exactly). After downloading the new FW the system tried to make a self-shutdown without any success. After waiting for an hour I had to make a hard shutdown and let the system cool down for several hours.
Next day I powered up the NAS but it wasn't able to boot. The front touch panel and the display above it were flashing periodically, about one second on and the next two seconds off. The processor fan was at maximum and the Ethernet RJ-45 green led was on and randomly blinking (i.e. negotiating with the switch). This front panel flashing continued for forever and the only thing that was working was a new hard shutdown by pressing and holding down the power button. I was not even able to acccess the boot menu options by pressing and holding down the reset switch on the back panel during a new power-up. The front touch panel didn't response to any touching.
After trying to find a solution in forums without any success I disconnected all cables and even pulled out the hard disks but nothing new.
Any suggestions?
Thanks for the update.
Glad that it is now resolved with the replacement unit.

So, if I gather what you are saying correctly, with the hard disks removed (label order) you are still unable to get into the boot menu?
Before RN516 display/touch panel stuck at 1 second on/2 second off, does display ever show "NETGEAR Storage Welcome" message? If not, then BIOS stuck even before trying to boot from any devices, USB recovery won't work at this stage. Is this a RN516 beta unit? becuase the symptom appears to be corrupted BIOS NVRAM or CMOS settings which was only observed on beta units. Could you please try following:
1. Hook up a TV or monitor to RN516 through HDMI port and let me know what is BIOS boot message(or no message) ?
2. Take out CMOS battery for 30 seconds, then put it back. To take out battery:
i/ Remove RN516 cover - Uncrew(7) from back, pull back half inch, then lift up
ii/ Remove RN516 back panel (2 screws). Battery is now accessible (Top near backplane)
iii/ Push tab to unlock battery and take it out
iv/ wait 30 seconds
v/ Reverse step iii/ ii/ i/ to replace battery and panels
^ No wellcome messages. I removed the battery too, but no success: now the touch panel is not blinking anymore but I cannot access Boot menu. Haven't tried USB-recovery yet.
I took a completely new, unused diskless 516 unit and put the RAID disks inside the enclosure in the original order:
Front panel : "Could not mount root RAID c"
RAIDar:
Status: Corrupt root
Firmware: (=empty)
What next?

Your new system had 6.0.4 on the flash.
I just put 6.5.2 on it.
I'd recommend uninstalling the LMS app you have on your NAS and installing the one from NASTools. There is a lot on your 4GB root volume.
It sounds like your old system will need to be RMA'd.
