Meraki MR32 u-boot downgrade?

Hey,

Im wondering if there ist a possibility to root the MR32.
My u-Boot version is incompatible. Is 2012.10. But I’m able to access the shell.
Is it possible to downgrade the U-Boot?

Or is there jo possibility to get my MR32 working?

Also I found openWRT file for the mr32. It’s called openwurt-bcm53xox-generic-meraki_mr32-squashfs.trx.
How to use this one?

did you read https://openwrt.org/toh/meraki/mr32#installation ?
doesn't mention a downgrade, but how to install openwrt.

Yes
I did all. I was so close. I got the MR32 download the bin via ftp but it wound install.

I talked in a different topic about my problems.

And I think there is no possibility to get an OpenWRT firmware for the MR32 right?

The is just the sysupgrade one and the weird .trx one

Hello everyone,

I recently acquired a Meraki MR32 unit and am interested in installing OpenWrt on it. If anyone has an OpenWrt NAND dump for the MR32, I would greatly appreciate your assistance. I have the RT809H programmer ready for use.

I'm encountering an issue with the message:

'UNRECOGNIZED COMMAND LOGGED TO CLOUD SERVERS.'

It seems this problem is related to the newest Cisco firmware, Bootkernel Meraki Build 25-201807091103-G1dfc8e26-aacharya.

Could someone provide or insert a NAND dump of an older firmware version where this procedure was still supported? or or a NAND dump with OpenWRT?

Thank you in advance for your help!

Just FYI:

  1. Create a seperate Ethernet LAN which does not have access to the internet.

From: https://openwrt.org/toh/meraki/mr32#installation (emphasis added)

I tried everything according to the instructions, but I always get a response to the commands.

'UNRECOGNIZED COMMAND LOGGED TO CLOUD SERVERS.'

Please don't quadruple post the same question.

How is an unrecognized command logged to the Internet if you didn't connect your MR32 to the Internet?

The device is not connected to the internet, and the problem is that the newer firmware is too restrictive. Does anyone have a NAND dump of the older firmware or a NAND dump with OpenWRT?

Thanks

Did you find this dump? I'm also looking for it. I have only NAND dump with 25-201712141532-G0bb86dd3-hamaki version.

I haven't found that dump yet. If you'd like, you can send me your NAND dump with version 25-201712141532-G0bb86dd3-hamaki, and I can try using it to install OpenWRT. We might be able to adapt the existing image to make it compatible.

Dear all,

I successfully loaded OpenWRT into the part.safe partition, but it seems that the system is running from RAM. Unfortunately, any changes I make to the configuration are lost after a reboot.

SSH is functional, but LUCI is not accessible.

I’m attaching the NAND dump with OpenWRT included, hoping we can make some progress to get everything up and running.

A big thank you to woytu89 for sharing their NAND dump, which I was able to build upon.

Here’s the link to the NAND dump with OpenWRT:
