Easy method to downgrade to previous version of the firmware

hi Guys,very good Info

but here my Problem to fix this …wdcloud 4TB do not boot to BLUE

Hi Support
,
Problem is that my WD 4TB cloud will not boot properly.
NO RED LED !!!
,
Cloud ran for approximately 1 year without any problems to access through software and browser there she

was always

a bit too slow and if you changed anything it took to talk up to 3-6 minutes to the change

had taken over.
,
Now is no longer possible to access, often it remains just loading the operating system hang, LED

Yellow, sodas just not “booted” pilaris BLUE LED.
,
After reset 4sec. she was sometimes sporadic “to see” but when copying data they broke easily

middle from (error 64) and was again not too sehen.Obwohl the Cloud BLUE!
,
The tips on troubleshooting, Lankabel reset etc. brought no improvement.
,
When you restart attempts
Off-web-30sec. wait-back power, and then wait whether to blue LED (if it did not work)
-Reset At power-on and wait until “Boot” successfully
nothing positive to put on new message LED YELLOW FLASHING (supposedly network error)
I’ve even used another network LAN cable
“RESTART”
did not help either!
,
The fact is:
-Lankabelverbindungen Are ALL ok
-Power Supply the cloud is ok, tested PSU with USB3HD.
-Cloud Shows sporadically after “restart” 2 messages 1.permanent Yellow Sytemboot 2.Gelb-blinkt-

Lankabeldefekt, but changes to permanent yellow after a few minutes again,
up to sporadic blue-permanently-ready (after about 1 hour to boot)
,
-If BLUE sporadically connect Workplace away are 2 folders / links times available times not,

1 times without 2 times 2 times 1 + 2 but with access (copy / save) Demolition 1 + 2 off!
,
Toll the now vorraussichtlich my over 2TB data have Datentot found because the cloud
any defect has. (NOT REPRESENT as possible Abruch)
-on Werkseinstellng reseten not run because I still want my data if possible !!!
,
I suspect that the firmware or board has an error (firmware update automatically! Error?)
or even the HD defect, since (if they boot times) but will appear in Windows after kutzem Access-

Aborts and connection is gone although BLUE!
,
Have now the forum found something: Downgrade the firmware to help!

,
Can it really not be. New firmware makes these problems?
And now to the small end consumer the judge?
Toll when the cloud allegedly is blue, but you can not even access it to try it.
!!! FAIL WD !!!

Bin for suggestions and help, if possible, be grateful.
Before I bring you back to the dealer and ask for my money back!
(with all the collected information)

on Time:I try 40sec. reset

update:
Have Kontakt with Support…this will help…
-have done Factory reset (40sec.by Power ON)
-Fact:Cloud no more work right !
-Boot 1 from 8 good “Blue”
-when “Blue” kopie only 1 Folder…then fail Conecting
-do not work by Init. in Bowser…fail by language selection

I hope Support Help me
