I want to rollback OS 5 to OS 3

anyone have a idea?

i can’t using OS 5 anymore, i need download service, but OS 5 is not support yet.
it using just share folder.

If data can be deleted,
format the hdd, initialize the firmware manually, enter the recovery mode, and install it with the current firmware.
however, I don’t know exactly what files are needed for initialization.

Has anyone do it?

Try to upgrade the firmware to 5.05.111 if your NAS does support it.

It solve most of my issues

I want to roll back to OS 3… NAS with OS5 is useless!!!

Unfortunatelly , it seems not possible.
The new firmware seems to improve the speed…

thanks you :slight_smile:

Not possible!

Here is a list wht else is not working anymore with OS5:

A speed increase means nothing if the people I share with can’t get access anymore.

-Enable “SSH Access” in web interface

  • Login via SSH and then,
    Type: dd if=/dev/zero of=/dev/mtdblock1
    reboot
  • After reboot you can access to “WD Recovery” web. Install original WD firmware OS3

It worked! thank you - I am back in business, ie., OS 3

  1. upgrage to DSM ( https://fox-exe.ru/WDMyCloud/WDMyCloud-Mirror-Gen2/ )
  2. move on with the installation of DSM
  3. Enable “SSH Access” in web interface
    Login via SSH from your first login (Or any of ligin with Admin privileges)
    Type “sudo su” and enter your password again. You are “root” now. Type:
    dd if=/dev/zero of=/dev/mtdblock1
    reboot
  4. After reboot you can access to “WD Recovery” web. Install original WD firmware OS3

Done this but cant apply the firmware, just endless circle loop in safe mode

Unfortunately WD have deliberately removed telnet access to device with the latest update.If you are in the UK please remember the 2015 Consumer rights act. Trading Standards reminded me of this!
This states under 46. Remedy for damage to device or to other digital content
(1)This section applies if—
(a)a trader supplies digital content to a consumer under a contract,
(b)the digital content causes damage to a device or to other digital content,
(c)the device or digital content that is damaged belongs to the consumer, and
(d)the damage is of a kind that would not have occurred if the trader had exercised reasonable care and skill.
(2)If the consumer requires the trader to provide a remedy under this section, the trader must either—
(a)repair the damage in accordance with subsection (3), or
(b)compensate the consumer for the damage with an appropriate payment.
(2)If the consumer requires the trader to provide a remedy under this section, the trader must either—
(a)repair the damage in accordance with subsection (3), or
(b)compensate the consumer for the damage with an appropriate payment.

If you have been inconvenienced by this (two weeks and counting of indexing) WD only suggestion disable shares, thereby inconveniencing again by not being able to access remotely, escalate for compensation. WD have breached the act by not showing any due care or diligence in the release of this flawed not fit for purpose firmware. They have pushed the CPU to its limits working 24-7 which has increased the temperature in some cases to detrimental limits shortening the lifespan of the product in doing so. Finally by deliberately removing any ability to revert back to a safe position (OS3) they have again breached the Act showing a lack of due care or diligence. I have a device I can no longer use as advertised, cannot revert back to a safe point, and in effect has become a paperweight. Sorry WD this is not acceptable, Have escalated my complaint and if needed will enforce the act to the courts. I suggest everyone here from UK do the same.
