You can use the command
du -h /tmp/mnt/data_persist/log/dumps/
/data_persist/ is on the CMU and not on the memory stick.
Salute everybody!
I end up manage to fix it!!!
First of all
thanks @
issam_isl and @
Tristan-cx5 for the right way and actually good advice.
I would like to describe what have I done. The issue was probably similar as mentioned
here at the post #7,777 · Oct 17, 2019 and concerned the big size of the log files, especially a dump. It's really true.
So, I had tried to execute the command
# ls -l /tmp/mnt/data_persist/log/dumps/
/bin/sh: /: Permission denied
but the response as we can see was negative. Than the next one was with
du command:
/ # du -h /tmp/mnt/data_persist/log/dumps/
du: /tmp/mnt/data_persist/log/dumps/: No such file or directory
and the result was not positive as well.
I do not why but eventually submitted just
# du -h and got really splendid result: there was full list of files and folders with relative paths like
./tmp/mnt/data_persist/log/dumps/ not absolute as mentioned above
/tmp/mnt/data_persist/log/dumps/.
Of course, then I read the the size of all folders and the interested one, namely,
./tmp/mnt/data_persist/log/dumps/ was exactly
500Mb!!! In my case the dot before the first slash
(./) was principal.
All other folders in the directory
./tmp/mnt/data_persist/log: saved_logs, saved_resource_data and error_logs were not so big, approximately up to 70 Mb. So, these folders I didn't touch and leave them as it is.
I just remove all files from directory ./tmp/mnt/data_persist/log/dumps/ by the command
# rm -rf ./tmp/mnt/data_persist/log/dumps/*
Than I put the memory stick into the usb port, so the update process was started and went on further. After 5 min I got the really fantastic message as the
"Version 70.00.352 software install was successful. Please turn ACC off and on again for changes to take effect". Next I removed the usb stick and put it into the laptop, downloaded the
ID7_Recovery_XX to the usb and return this memory stick to the usb port of my car.
Al in all I execute some other commands for getting the ability of the CMU installing tweaks:
# cp -r /mnt/sd*/XX/* /mnt/data_persist/dev/bin/
# chmod +x /mnt/data_persist/dev/bin/autorun
# /mnt/data_persist/dev/bin/autorun
Finally I finished the update/downgrade in compliance with the update-manual: removed usb stick, close all doors, lock vehicle with remote and so on.
After 4 min I switched the car in ACC mode and got absolutely functional and rooted CMU.
The tweaks installs, the SSH works! The AndroidAuto (AA) is possible to install but it doesn't start after the connection of mobile. It's probably closed or well-secured for FW 70.00.XXX
If somebody knows how to lunch the AA using the mentioned FW, let me know, please.
Ok, the main result is
the CMU is unbriked and works as if nothing had happened.
