Sonicwall 240 appliance

Sounds like it's bricked.  If it's a trial you can request for a replacement :)

http://community.spiceworks.com/topic/105234-sonicwall-pro-1260-bricked-i-can-t-reset-it-after-spontaneous-power-loss

I have all blue, green and yellow light flashing continuously.... any suggestion

Boot into Safe Mode by pressing the Reset button (typically with a paper clip) for 7-12 seconds. The SonicWALL requires up to 90 seconds to restart. The yellow Test LED is lit during the booting process.

Reset does not work, even if I hold it upto 30 seconds and continue to flash. It used reset within matter of 5 seconds before this problem surfaced

Like the detail information about future issues, but, my issue is flashing lights that does continues to flash after reset. May be there is no fix for it but this is the most detail info I got and take it as partial solution

Thanks.

What color are they all flashing? Are they all flashing the same color?

If you unplug it and wait for 2 minutes then plug it back in...do the LED's flash all over again?

Try this...its a hard power cycle. This is kind of difficult to do with one person but I have done it before just myself. It will help if you have another pair of extra hands.

For 90 seconds you are going to keep the pin pressed in the reset pin hole. Do not remove it until the 90th second is reached.
The TEST LED light (yellow) should remain on until it has fully loaded the firmware and performed its internal tests. This will reset everything back to factory defaults.

If it works it will revert to the default values: Gateway: 192.168.168.168, IP: 192.168.168.X. "X" can be 1-254 (excluding 168). You'll have to assign your NIC this static device. DNS is anything...four 8's.

Let me know how it goes!

all lights are flashing except red... I will give it a try on Monday and update the comment

Ok. Do you mean all lights are flashing red? Or do you mean they are flashing blue and yellow?
You said "except red".

I only see flashing blue/ yellow and green

keeping the reset pin pressed for 30 seconds, logically does not make sense. However, I did try the entire 90 seconds cycle and it is still flashing.

Sonicwall is bricked. It matches the article posted for bricked sonicwall and it sounds like there is no fix for it

Interesting LED sequence stuff. I never knew! Thx

Keeping the reset pin pressed for 30 seconds, logically does not make sense. However, I did try the entire 90 seconds cycle and it is still flashing.

I can understand why you'd think that but its a physical button that has time sensitivity built into it, which is why when pressed for 1 vs 5  vs 10-20 vs 90 seconds...they all have different results. This 90-second cycle remedy comes straight from SonicWALL engineering - we are Platinum partners and get access to engineering KB that general public does not. This case is extremely rare (I very, very rarely see a bricked SonicWALL), and I've never come across the default colors flashing of each LED category as you described. In any case, I have remedied classic bricked LED symptoms before using this 90-second cycle, which is why I wanted you to at least try it before throwing in the towel.

At this point, like you said its unequivocally bricked so I'd phone support or distribution and get an RMA to replace this unit.

Best of luck with the new one...sorry we couldn't recover this one for you!

Thanks for the points. I'm glad I could help!

Tried again no luck... Thanks for your help. I would probably need to call support for replacement
