Should probably do DD if=/mtd/(whatever of=(whatever).img
That would create imgs
It seems invalid/corrupted can you try to grab it in a .img format
Also could you run the 2 bash script here and send the results (guide on how Todo it is there too)
ah apologies, the new_mtd.7z are labelled bin but from what you said they were created via dd so should be named .img can you rename one to test else I am a bit stumped as did them all 1 by 1
also, these files are from the generic isp locked ones which show as V2 unit fw 2.0.5.210476
both fail
/tmp/mnt/sda1/mx4200 # sh gpio-test.sh
/base': No such file or directorygpiochip0

gpio-dump.sh: line 5: arithmetic syntax error
There are 2 buttons on the base and one multi colour LED on the top
Yeah that didn't work
Ah damn, so I've just use DTS from V2, well ig it should be fine
Well I'm attempting to build the Openwrt Firmware as we are speaking, I doubt WiFi will work since we are missing the 2 files
Well here we go (untested)
Initramfs Factory
Initramfs uImage
SquashFS factory
SysUpgrade
I can't guarantee that it won't brick you, id recommend testing Initramfs first and ALWAYS make backup first
If you do want to flash Openwrt just download SquashFS factory and flash it via the Linksys web interface
(ONLY FOR V2, V1 will come when my laptop gets fixed)
ok so neither of the initramfs worked

Jumping to AARCH64 kernel via monitor
Just going back to dumping the flash, seems DD wont work due to the ecc data on a nand chip.
Looking at Linksys EA8500 uboot damaged after wrongly flashing with empty $loadaddr - #35 by GloooM it can be done via the main console though so currently looking at that method.
Is there a specific partition you need for files other than a whole backup to be useful ?
Nah not really, full back would be most useful to us
The real Question is why isn't the kernel starting
Ok, have revised the filesystem with start and end values in HEX as I will try and grab them again shortly via the console dump command.
There seems some discussion whether the u_env and ART partitions can be retrieved correctly in this manner but will test and see.

Try this
Trying to add support for a device that you don't own and rely on other people to possibly brick their devices is rather unusual.
Yeah, I do own the device but this issue is Linksys Made a V2, I would do it all myself but my laptop died waiting for that to get fixed and I'll do V1 without asking anyone to test, I just wanted kernel up and running through initramfs
