Mongcharlie Yes. I had this kind of problems because a bad USB drive
Dudu7 head unit reboots by itself
MihaiFlorin i'll get a new micro SD today too to try it out
Hi, I have a DUDU7 11.5 with 12GB/512GB unit installed a few weeks ago and updated to 3.5. It was working well last few weeks until last weekend when I was doing very long drives for several hours at a time and noticed that it would turn off and then reboot (with the Google boot animation) at random times for no apparent reason. It did it 3-4 times during the day, that I noticed.
I normally don't have any USB devices plugged into the unit, except for 1 to charge a GPS tracker (power only, no data). This last weekend I did have my phone plugged in to charge a couple of times. And now I come to think of it, I think the random reboots occurred while I had the phone plugged in.
Later that day I drove back home 3-4 hours and the phone was unplugged and no reboots at all.
Could this point to the USB errors that could be causing reboots?

Mongcharlie Is only the TPMS USB receiver connected? Are other USB ports not connected?
I label the folders on google drive
one folder has the ylog of the reboot with just the tpms connected (happened in the morning)
the other folder happened last night, (nothing connected to the USB)
is it possible to go back to the last stable version? maybe os 3.0 ? the reboots are inconvenient
TIA
Mongcharlie I'll submit the logs to the engineer when he gets to work tomorrow, Monday, and if he doesn't have a good idea, I'll tell you how to get back to OS 3.0.
thanks,
i'll keep updating the random reboot for your BUG team.

Mongcharlie Still haven't found the cause of the reboot
Please do this, clear the history ylog, connect the TPMS and DVR separately without rebooting, and print a 5 minute log to help us find the USB anomaly issue.
There is no good solution for the reboot issue, the cause is unknown.
Please downgrade back to OS3.0 version, steps are as follows 1: Download OS3.0 version from this link, unzip it to the root directory of USB flash drive (https://drive.google.com/file/d/14M6FXZk2nPzdHyLwyy1pQ1pAYZyQmC82)
2: At the same time, put this file into the root directory of USB flash disk (https://drive.google.com/file/d/1mb2CoCQcstpSPWyB0TxI0wjEj_XQGhHW/view?usp=sharing)
Insert the USB flash drive into the USB port, the USB flash drive will be downgraded automatically.
i did the downgrade to 3.0 Last night, everything went fine. the system worked great for awhile, but then i got another reboot today.
here is the ylog file

Mongcharlie OS version 3.0 has the same problem, so you can rule out a system issue. It could be a hardware issue.

so do i have a bad unit?
How can i get this resolved?
Can i get an exchange?

Mongcharlie Yes, contact DUDU sales

Mongcharlie Contact mekede
4 days later
So I found out that it's shutting down because of a thermal issue. It rebooted again today, but I already downloaded ADA 64 and immediately opened it up right after the restart the thermals we're all very high. The temperature drops down very fast and becomes stable at about 45c 
Also, I didn't mention this before, but whenever I turn on any app, the fan will start spinning up and turn off.

Did your issues get resolved?
Update:
looks like i got a bad unit, working on getting a replacement with mekede. I'll keep the post updated
