Unbrick mycloud 1 bay gen 2

[tiomiguel]

OPk I have toc download these files to hard disk, but hard disk have some partitions, and tutorial should explain with clarity WHERE these files have to be extracted.

I will probe alternative procedure and expalin here with detail everything I do.

Not sure how this would work on a CD distro. They are copying the files to the Linux environment. Then copying them to the WD Cloud disk.
I have a Linux system so I just connected the disk to the linux system and followed the instructions.

I used a Ubuntu boot USB stick when unbricking (using Fox’s 1st gen directions) my first gen My Cloud. Did the same. Files copied to the Linux environment, unpacked then copied them to the My Cloud hard drive as the directions indicaed. Had the My Cloud hard drive attached to the PC via a SATA to USB adapter. Done it numerous times, on a variety of different hard drive sizes, with no problems.

I don’t have a gen 2, which uses a different unbrick procedure, so I’m not sure exactly how it would work.

Generally the files would be downloaded into the working directory one is in when using the terminal/command line window. Then one would unpack those files in the same directory. Then one would follow the rest of the directions.

OK I applied second procedure and could arrive to this screen

Safe Mode

Your device firmware appears to be corrupted and your device is currently running in Safe Mode.

Please download the latest firmware from the WD Support website at http:\www.support.wdc.com and upload the firmware file below:

Firmware Version: 1.01.007

---

First of all posiible firmware for this device can be 2.xxx or 0,4xxxx - I do not know what version i have- Have to tried to update first last official firmware 2.xxx and light goes blue blinking for few seconds and then red solid and shows 0% … and nothing el se. i have tried with last 0,4 firmware and even that. I have read in other post the same situation, but nobody gave a solution

I can't unbrick my MyCloud Gen2

Hi! I tried installing Debian on my MyCloud Gen2 following the steps at https://ftp.anionix.ru/WDMyCloud/WDMyCloud-Gen2/Debian/ and it got bricked. It shows a yellow light, and it connects to the router and gets an IP (it replies to ping) but it has no open ports, no way to connect to it (no web, no ssh, nothing) Then I tried unbricking it following the steps at ht tps://ftp.anionix.ru/WDMyCloud/WDMyCloud-Gen2/_Unbricking_en.txt and it almost worked. I got to the “safe mode” where I was suppos…

I am near to sucess but,…

I have WDBCTL0030HWT -10 means this is gen 2 with 2xxx firmware so why shows Firmware Version: 1.01.007

No. You cannot load the first gen v3.x or v4.x firmware to the second gen v2.x My Cloud. Doesn’t work like that. Nor can one load the v2.x firmware to a first gen v3.x/v4.x My Cloud. Each generation has slightly different hardware and use different firmware versions.

Try, if you haven’t done so already, downloading and using the initial firmware 2.10.302 (10/7/2015) for the second gen v2.x single bay My Cloud units. Links to most single bay My Cloud units can be found at this link:

WD My Cloud v3.x, v4.x and v2.x Firmware Versions Download Links

UPDATE (4/15/2022): WD has terminating OS3 support as of April 15th of 2022!!! Generally one’s OS3 My Cloud will remain operational and accessible on the local network. WD supported remote access service (MyCloud.com / OS3 mobile apps) has been be terminated. The second generation single bay My Cloud ((P/N: WDBCTLxxxxxxx-10, FW 02.xx.xx)) unit is not affected by the OS3 support termination, the second generation single bay My Cloud can be updated to OS5. UPDATE: It appears WD is now blocking us…

Also as a troubleshooting step, after uploading the My Cloud firmware to the unit, try a 40 second reset.

[tiomiguel]

OK I have tried with first firmware before posting. I will try a 40 second reset

[tiomiguel]

Nothing

[tiomiguel]

At the end I WAS ABLE to unbrick with first procedure, 40 sec reste and loading last firmware. I was able to do it with 2 Tb and 1 Tb hard disks. everything seems to be ok. This woluld not have been possible without your support. thank you very much

One of the 4096-705698-000 boards is solid red + blue and ethernet lights does not light. I understand board is dead?

[rac8006]

You should be able to test each board using the good disk.

[tiomiguel]

all boards are ok except one, with solid red-blue light.

It’s possible to have a dead board. But just to make sure, check the P/N number on the bottom of the enclosure (if you haven’t already) to ensure it ends with “-10” (2nd gen). If the board is dead may want to contact the seller to complain or swap with another enclosure.

Hi, I have same my cloud as tiomiguel (WDBCTL0030HWT -10). I’m do not have any knowledge in Linux, using commands, etc. I just would like to unbrick my mycloud.

I tried to follow the first procedure and managed to install telnet on windows 10, but I just do not know how to connect to the Mycloud as I don’t know how to do that and understood I have to know the IP of the Mycloud which I do not see in the rooter page.

I installed a Linux like thing to have a terminal, SystemRescueCd, on which I boot via USB stick. I connected the HDD in an icy box via USB. I tried second procedure, but there I guess I’m blocked on step 6. I have message “cp: cannot stat ‘uImage-wdrecovery’: No such file or directory”.

I think uImage, uImage-wdrecovery, uRamdisk and uRamdisk-wdrecovery must be downloaded somewhere but don’t know where/how. I have them in a “root” file on a USB stick.

USB stick is “sdd” and my cloud is “sdb”.

Can someone be so kind and help a very beginner to fix that?

Thanks a lot in advance.

Below list of “commands” I entered:

It failed to copy the files from the USB stick to the boot folder.

this is because you are attempting to copy from the /mnt/boot/boot folder context, and no files exist there yet.

You need to mount the USB stick and copy the appropriate files from there.

mkdir /mnt/usb
mount /dev/sdd1 /mnt/usb
cd /mnt/usb/boot
cp uImage-wdrecovery /mnt/boot/boot/uImage
cp uRamdisk-wdrecovery /mnt/boot/boot/uRamdisk

Hi, Thanks a lot for your support. It seems I was able to enter the commands with success. Unfortunately, I still have the flashing red light so I’m lost. I tried 40 sec reboot. Still same issue.

Should I do something else under Gparted? I see I have 5 partitions with warning flag. I would like to do a screenshot but no clue how to do that under SystemRescueCd.

Should I give up as mycloud motherboard is dead?

you will get the flashing red light, but you will get a web interface to come up if you put the IP in the address bar. It will tell you “looks like your firmware is corrupt, please choose a firmware file to upload” or some such.

This is where you can actually send a real firmware image to it.

[Hans1984]

Thanks a lot. Indeed now the mycloud is visble in my router page and I’m able to see its IP address. I entered it and saw the safe mode asking to update the firmware. But I’m stuck again. I upload a file “My_Cloud_GLCR_2.31.174.bin” it goes to 100% but seems to be blocked even after one hour waiting. See below screenshot. So frustrating to have issues at all steps. Should I look for other files to update the firmware?

[Wierd_w]

I suggest using this firmware for debrick.

http://download.wdc.com/nas/My_Cloud_GLCR_2.21.126.bin

I have tried newer ones, but they fail during the volume setup in various ways.

also-- that screen does not auto-refresh after it reboots… you need to press f5 after it reboots.

[Hans1984]

Hi, thanks, I tried this one but still same issue, I let it all night long. This morning I tried to redo the whole procedure. I have flashing red light when i plug the device to the router. I started uploading the firmware and it blocks at 0% and solid red light on device. I will wait an hour and try to refresh. But i’m afraid I will again have same issue.

[Wierd_w]

Did you format the other volumes before debricking?

I know that Fox’s instructions dont say to do so, but you should. When the pushed over firmware boots, it tries to mount volume 4 and volume 7 for internal system process scratch and persistent storage purposes. If it fails, it will go into safe mode and tell you that the firmware is corrupt, much like when you push the recovery images over.

Format all the volumes with ext4, then put the recovery uImage and uRamdisk on. the firmware flash should succeed after that. If it doesnt, for whatever reason, hit F5 on your keyboard once you see the solid red light (that indicates that the new firmware booted, but it has a problem) and push the firmware a second time. Shouldn;t be necessary with that older firmware-- I only ran into that with newer ones, but still.
