Unable to boot on QY7201NB

[spafrost]

Hi!

I am trying to boot leadsdtools on a QY7201NB unit in a UK Delivered Nissan Leaf ZE0 24kwh, but have so far been unable. I wondered if anyone had hints or tips that can help me.

• Unit is QY7201NB in a UK Delivered Nissan Leaf ZE0 24kwh.
• I have 2x 16GB Full Size (No adapter) SD cards that I have verified are not fakes using f3 tools.
• I have extracted the .img from the .tar.gz using 7zip.
• I have tried writing the image with Balena Etcher, Rufus & W32DiskImager on Windows 11 Enterprise
• I have also tried writing the image using dd & Balena on Linux Mint Cinnamon 22.3
• I have tried using several SD card readers, including a UGREEN, Surface Laptop onboard & a USB-C dock.

In all of these attempts I am greeted with the following when using the "Software Update" method documented in the Wiki

Some information that may be useful or not!

• When flashing is complete both Windows & Linux systems automatically mount two drives a 524mb FAT Partition and an 8.7GB fat partition, neither OS shows files in these partitions.
• I have pulled the source and am re-compiling the software myself - but can't see any information so far on how to configure an SD to run the compiled software.

Any help appreciated!

Hi.

Could you try few old versions of leafsdtools? There seems to be some kind of issue on latest release.

I am just working back through them now,

I see the same behavior on 108, 107 & 101. I am trying 104 now. All flashed on Linux Mint 22.3

Thanks for such a quick reply, possibly a GitHub world record !

I tried every version with the same result,

I expect that there is either an issue with my flashing method or something different about the unit.

My new SD adapter should arrive today, I will update when it does.

If that doesn't work - is there a way I can dump my working nav card to check if there is something different ? Happy to source any required hardware!

No luck with the new SD adapter, I see the same "UPDATE FILE READ NG" message.

I found out that my serial number ending "NB" normally signifies a unit in a Japan delivered car, which does add up - as the very first Leaf models sold in the UK were Japan built - and differs from the "NE" ending serial I see in your examples for a European car.

I wonder if the boot process/security is different on "NB" units.

Looking around the web, I see its possible to "cross-flash" the NB to other firmware - I wonder if Nissan did something similar for the early delivered cars that means there is an incompatible difference?
