Recovery for empty SD Card
#1
Hi,

I hab an issue with my SD card and it wasn't readably anymore. Now I can't use the recovery USB stick to restore my netpi. How can I create a new SD card with a base image, so that I can use my netpi again. Is there any base image I can use for that?
In other threads I read that the netpi OS is specific to each MAC adress of the netpi. Is there any other recovery method besides an USB stick with the recovery tools?

Hi there,

what do you mean by "not readable any more"? Is this message something the netPI is printing on the HDMI output when you power it? Do you have a screen shot?

What else happened to your netPI device exactly? When did this effect happen? Was your netPI under operation and then it happened accidentially? What type of application are you running on your netPI? Is it an application that puts a high write load onto the SD card? An SD card has a limititation of write cycles by its very nature of its NAND technology used.

What is the MAC address of your device printed on the label? What is the model name and the variant code printed on the label?

Thx
Armin

Well, 

I see in the production database that it was manufactured 2021-03-02, so it is a brand new device in my eyes. It also have included the white colored industrial suited SD card from SANDISK where we had no problem with before in terms of losing data. So I am wondering why it got "broken". This is absolutely unusual.

What I will do next is sending you a common 8GB SD card image that you can burn your SD card with 1:1 using a program like Win32Diskimager or Balena Etcher ... but after that you need to replace one single file which is the correct device label file for your device B827EB10AB28 needed for booting. So after burning the SD card mount it on your Windows or Linux system. The system will indicate two FAT32 partitions. The first has a folder named "nvd" in it. In this folder copy the file "device_data" that I will be sending to you as well. After copying it insert the SD card back into the netPI socket again and boot your netPI device as usual.

Hi Armin, I'm facing a similar issue, the SD card of one of our gateways was damage due to customs verification at the airport, we manage to use the raspbian image as a "not so good" replacement of the original OS, please can you help to restore the gateways to its original OS. I'll appreciate any support that you can give us.
