Backup of internal SD for NEX 8200 — AVIC411 Forum Archive

Posted Apr 26, 2017 · 16:43 UTC#1

Hi,

I will get my 8200 this weekend and thought, it would be a good idea to have a backup of the internal SD card.

Is this possible with the DEV MOD ?

I thought, I saw some script here for the x200 series, but I am no more able to find it.

Thanks in advance for your answer !!

Thank you. I was not sure, whether this was also working for the x200 units. Somewhere there was a thread with firmware versions and scripts, where the x200 units had been mentioned.

Just one more dummy question: That image is a protected/encrypted one, right ? If I dd it back on a backup sd card, will it then work, if plugged into the internal sd card slot ? Sorry for this dumb question.

Hi,

I now did a backup of the NOR and the internal SD card. I also put the AVIC.img on a 16 GB SDHC card. The image size was 15.817.768.960 bytes. I used Win32DiskImager for this.

Now I opened the top of my 8200 NEX unit, but do not see the internal SD card. Do I need to get that board out, which I can see from the top ?

Did you ever get the SD card image saved. I need a copy of it to fix my 8200. If you can post it here that would be awesome. Or if anyone knows where I can find it.

The radios use a firmware on an SD Card to run the radio software and apps. Sometimes, over time, this card gets messed up (corrupted) and stops working. SO we have to replace it. It's inside, so you have to take the radio apart to get access. By replacing these cards you can fix radios that have issues with booting up, or give error messages.
