I know maybe this is off topic, i have canon eos 250d, get error 70 after some water damage (the camera catch a rain).
The error show when i try to take pictures, and when i try to get in video mode, it got frozen
I suppose this is an nvram corrupt, i've cleaned the water damage from the mainboard and it's still showing error 70
Can this is fixed by running magic lantern and resetting the nvram? i don't really know what to do
I see some post on this topic : https://www.magiclantern.fm/forum/index.php?topic=4105.0 and he had it fixed with some magic lantern help
EOS 250D isn't supported by ML.
Please contact Canon support or a local repair centre. You might try to reflash firmware 1.0.2 and see what happens. That's all.
That's right - we are not yet able to run user code on this camera.
However, if you want to diagnose it yourself, you could probe for the UART pins (https://www.magiclantern.fm/forum/index.php?topic=7531.25) on the mainboard; there you would see the actual error message behind ERR70. There are over 1000 different conditions behind this error code, but... since the error appears when you try to capture images, my best guess is that's very unlikely to be fixable by software.

I've tried it, and they said i need change the whole mainboard

U connected my UART to these pin, am i using a right pin or is it on the other side? https://prnt.sc/qpj0e2
This log comes from the MPU - a secondary processor. ERR70 is a class of errors triggered from the main processor (the ICU, in the above logs). Its UART TX (aka TXDICU) pin should be nearby (here's on EOS R (https://www.magiclantern.fm/forum/index.php?topic=7531.msg212071#msg212071)), and on all other models, the startup log on that pin is a lot more verbose. You could try probing for it.
So far, this is the second camera with "verbose" messages from the MPU, besides EOS R (https://www.magiclantern.fm/forum/index.php?topic=22770.msg211964#msg211964), but I don't remember anyone probing for UART pins on other DIGIC 6/7/8 models, at the time of writing.
In any case, these logs are very useful for an initial ML port on this camera. Re-hosting your PCB image for future reference.

Side tangent: I have probed the 200D and got no 'verbose' messages.
