update-firmware on Xiaomi Mi Robot Vacuum V1 fails

[keros]

Hi

I got today a new Xiaomi Mi Robot Vacuum (V1) and wan't to install a custom firmware (Valetudo).
But fail with some errors.
I already did this about a year ago with an other cleaner of the same type which worked fine.

The robot is on accesspoint mode (192.168.8.1).
I'm connected with an debian laptop.

mirobo --version
mirobo, version 0.5.3

miiocli --version
miiocli, version 0.5.3

At first I get the token which works fine:

    checksum = b'zBKBIF7b8IUd53zl' (total 16)

After that I did some simple tests:

miiocli vacuum --ip 192.168.8.1 --token XXXXXXXXXMyTokenXXXXXXXXXXXX status
Running command status
<VacuumStatus state=Charging, error=No error bat=73%, fan=60% cleaned 0.0 m² in 0:00:00>

But device info and vacuum info fails:

Do I something wrong?
Is maybe the firmware version to new? (How do I get the current firmware version?)
If the firmware is to new, is there info I can provide to fix this?

[rytilahti]

The update response is odd, but looks like the debug printout happens before the parsing happens. If this device is the new hardware revision of the gen1 vacuum, there may have been some incompatible changes.

If v1 is the first generation rockrobo/xiaomi, it is a known problem that it doesn't respond to info correctly when not connected to the cloud service, so that's expected. Why the update is not working, I don't unfortunately know an answer.

[keros]

Thanks for the infos.
After connecting the robot to the cloud info works:

But at leat i have now the firmware version 3.5.4_004010.
Has someone already tried this with this version or newer?
Should it work?

[gitcob]

I have version 3.5.8_004018, I think it's a early model of V1, and info doesn't work either. Not sure how to connect to both the cloud service and still have an access point? I get "unable to parse message payload" for info and update-firmware. Didn't try any of the other commands yet.

[gitcob]

I did a full factory reset like here, got a new token and tried again. Info still didn't work, but uploading the firmware did! Valetudo works for me now.

[keros]

Read the docs and everything gets clear.
https://valetudo.cloud/pages/knowledge_base/supported-roborock-devices.html

Does not work on version >= 4004 (I think this is the firmware version part after the _)
Because my device is to new (factory date 05.2020) a factory reset will also not work (only brings me back to the version I already have which is to new)
So on this approach I'm screwed.

But Dennis Giese made an excellent how to hack it anyway tutorial.

I just have to find my UART cable and also some time to remove about 100 screws from my robot

Thanks for all the help.

[mmoscher]

@keros did you managed to get your Vacuum V1 rooted? My device is too new (factory date 09.2020) as well, not yet sure if I really would try to root it using a UART.

Thanks for your response 👍

[keros]

Hi yes I rooted my Vacuum V1.
The process is nearly the same as in the video for the (Roborock S6/T6).

On the disassemble part:

You don't need to remove all the parts.
The wheels can stay in place
Also the motor for the side brush can stay in place.
If I remember correctly the mainbrush can also stay in place (not sure about that)
There are 2 very long screws -> remember the position (they fit also in other holes)
Try not to pull on the cables to much when you remove the connetors from the motherboard (was harder than it sounds)

On the flash part:

I did not solder the wires (I did it solderless by holding)

From The cheat sheet:
https://builder.dontvacuum.me/x6cheatsheet.txt

I did not do the following (I did not find the string in these two files -> both partitions):

sed -i -E 's/dport 22/dport 29/g' /opt/rockrobo/watchdog/WatchDoge
sed -i -E 's/dport 22/dport 29/g' /opt/rockrobo/rrlog/rrlogd

After I disabled the firewall and had the root password written down I reassembled everything.
Then I started the vaccum wlan (reset wlan settings) and connected via ssh to the robot.
Then everything runs the same way as in the video (get the firmware, copy it on the robot, ...)
