Thanks for your replies!
I disassembled my device. It appears mine doesn’t have a connector soldered on, like yours. I ordered this cable : http://shop.clickandbuild.com/cnb/shop/ftdichip?productID=53&op=catalogue-product_info-null&prodCategoryID=105
It seems to match the specs to me.
I will solder cables to the board and hope I can get it to work.

Have a nice day

Thank you so much. Your article helped me fix the broken NAS :smiley:

It’s an old post but i will try the experiment as i have nothing to lose and now try to fix things instead of throwing them…

so here is the noob question :
Can i use the following product for the missing 5 pin connector ? if not can someone redirect me to the electronic part i should solder?

Hi!

I’ve tried to boot after into Linux afterI loaded the uImage und uRamdisk, but I always get the Error
“Verifying Checksum … Bad Data CRC
Ramdisk image is corrupt or invalid”
How should I proceed?
I have no clue what to do, I already tried different uImage and uRamdisk files from the EX2 Ultra GPL Source Codes Downloads.

Thanks for any advice!
Sincerely
EX2Ultra

Thank you very much! This tutorial helped me to bring my broken NAS back to life!
Lessons learned:

  • On Ubuntu 20.04, minicom did not respond to keyboard input. Using putty instead, it worked right away!
  • bootcmd on the Marvel boot prompt uses single quotes instead of backticks! this needs to be replaced during copy&paste

Good afternoon everyone. I own a WD EX2 Ultra out of warranty.

WD support has not given me more support than the 4 and 40 second reset.

The problem is that when canceling the AutoBoot, with the prompt in Marvell>> I have not been able to carry out the correct command to reset the firmware.

It always starts in Safe Mode and does not recognize the power to load new firmware.

On the other hand, when booting completely, the user is not root but another one with which I cannot enter with root/mycloud.

Attached evidence…

I know for the original user who was bricked upgrading from OS3 to OS5.

He hasn’t answered me with the password yet.

Any help to do a forced reset that 40 seconds does nothing?

Thank you very much for the support.
