Bricked F5-420 after TOS 5 install / Update

Post by Oddie »

Right first of all i updated to TOS v5
it rebooted and was working fine..
it then said there was a new AUTO update available (which i did)
woke up the next day to the NAS being off ..


After trying to turn the unit on

it either just sits with all HDD led lights on RED
with the green power led on with NO LAN Led

Go's into a boot Loop (none stop rebooting)

or wont turn on at all ...

====================================================

No matter what I've tried its still not working...
with or without the Hard Drives connected.

Things I've tried & tested.

I have a second USB drive with TOS version 4 on it
It dose the same with that USB drive in,

i have reset the Bios / Clear Cmos on the Motherboard,
by using the jumper header.. (see Photos)

Also tried taking the 2032 battery out
and doing the Tweezer short across the terminals points,
and replacing the old battery with a new one
encase it was flat ,


Anything else i can try ?


Also Terramaster why don't you sell new replacement motherboards on their own
and make the replacement USB cheaper as the verbatim one you use are only £7 new
and your charging customers of your products £45 for it
or at least sort your main web site support / download area
with all the downloads ie firmware's, TOS / Tnas versions for all of your products
with any important software updates and manuals


sorry for the massive overload of data and the rant .
but im just frustrated after 3 days of trying to get this working again

Also I've just purchased the 12pin to 15 pin VGA converter lead
to use with the unused VGA socket on the motherboard so i can
log into the Bios and the base line Linux OS directly to the box
to see what's going on in the boot loading screen to find out when its hanging
ill update any info when it arrives ..

if anyone else wants root access to their box
to trouble shoot you can get the lead here https://www.aliexpress.com/item/32808546166.html
all you need then is a USB Mouse and Keyboard plugged into the back of the NAS

The equipment should not be damaged just because of updating the system. Do you hear a beep when you start F5-420? If you can hear it, it indicates that the motherboard hardware is still OK. Please try to rebuild your USB boot system:

Well good news and bad news .
The unit was faulty but it was still in warranty and was checked by them after going through the RMA procedure.
I did get a full refund, but I couldn't get a replacement as they no longer stock any terramasters product's
At box.co.uk

So I've had to get a 4 bay asustor 4 ..

Yeah, there's a 2017 serial number, so unless that store sold really old stock to them within the last year, this seems like a lie.
