Unable to Boot or Factory Reset ReadyNAS NVX Pioneer (RNDX400E)
Hi everyone, I ran into this forum thread while searching for answers to a very similar if not exactly the same problem. I have a Readynas NVX Pioneer edition and would really appreciate your adv...
If it is "could not properly extract..." that would suggest corrupt firmware on the internal flash as a possibility. This problem generally isn't observed until a factory reset is done so it seems likely. USB Boot Recovery might fix it but that can lead to the EEPROM getting corrupted.
Don't need to use the serial console to troubleshoot that, though it is an option.
As the NVX is 32-bit care has to be taken to ensure the 32-bit kernel is in the right place if manually extracting a copy of the firmware onto the internal flash, I think. If you go down the manual route you can either put a copy of the firmware image (don't put a zip file on, put the image) on a USB key or copy the firmware on some other way e.g. download it from a http (not https) website.

If you could help I'd be very grateful, though I understand this link is from a good few years ago. I did try PM'ing the saviour in the other thread, though PMs are now disabled for that account (@mgdm-ntgr).
He's no longer with Netgear. You can PM him via mdgm instead. Maybe try the current mods ( Marc_V and JeraldM ) first.
This sounds like corrupted flash.
Morning all, small update with some info asked for by Marc_V in pm.

Morning all, Happy Tuesday.
I connected to the NAS over the serial connection with some success.
I can read the serial debugging but cant send any keystrokes - not sure if that's normal.

Update: I have straightened out my issues with sending keystrokes to the serial pins. I had a twisted wire, posting correct setup here for posterity.
I'm using a regular USB TTL Serial cable, Male USB at one end and 4 female jumper pins at the other. Similar to the cable here.
Numbering from left to right as you look at the pins on the back of the NVX, the jumpers are connected like below. I have not connected the red Voltage jumper as that seems like asking for trouble.

With this improvement I can send characters to the NAS using Putty set up for Serial Comms at 9600 Baud.
When I try to log in with random credentials, the proper "Login incorrect" message is shown. However when using the default credentials (admin, netgear1), on the first attempt I get:
nas-A9-AB-4C login: admin Password: No directory, logging in with HOME=/ Debian GNU/Linux 4.0 nas-A9-AB-4C ttyS0 nas-A9-AB-4C login:And on subsequent tries I get:
nas-A9-AB-4C login: admin Password: No directory, lo Debian GNU/Linux 4.0 nas-A9-AB-4C ttyS0 nas-A9-AB-4C login: admin Password: No directory, lo Debian GNU/Linux 4.0 nas-A9-AB-4C ttyS0 nas-A9-AB-4C login:When I run this through a logic analyser, I can see that this is definitely the characters being sent, there are no overwrites of the "No Directory" line.
Also I have heard back from a netgear customer support email regarding a paid support case so fingers crossed.
Normally you'd log in as root, using the NAS admin password.
