Minix U9 FW0008 - Rebooting itself

I had the box for about 2 years. It does sometimes reboots initially, but not often. Nowadays, it reboots more often. Not app related, as it happens even when I do not have apps running (Cleared all background apps as well). Not heat related, as I have a fan beneath the unit. Not wifi related, as I use Ethernet. Not adapter related, as I had a 3-pin plug direct to the unit. So, I can only conclude that it's a hardware issue. Could be PSU or unstable motherboard or poor chipset configurations.

Don't think this issue can be resolved with the current sets. Can only hope to get a better model in future.

Could be PSU or look at my post...

I can understand your frustration that your device is currently exhibiting problems but as with another member previously posting under this thread, you're also guessing, wildly!! It could be your regional tidal patterns or our orbit of the sun too if we're playing the guessing game ;)!!!

Before assuming it's a hardware failure without any direct evidence, in the first instance try a factory reset of the device :).

Have you also tried disabling all CEC options?

Or, have you at least tried clearing the system cache?

You don't list attempting any corrective action other than "clearing background apps" which could have multiple meanings.

The simplest explanations tend to be the right ones, so before jumping on the "this must be a hardware issue" bandwagon, try some simple troubleshooting first!!

If that still fails then indeed, look at the PSU next. (The PSU is actually inside the "adapter" as you've labelled it, so they're actually very easy to replace :).

Factory reset - done that.
CEC options - done that.
Clear system cache - done that.
Searched for solutions online over the year and followed suggestions - done that. Even built a fan below just to cool the unit.
I'm deducing it as a hardware issue after trying out all possible suggested solutions, so if you cannot accept that, then too bad. A PSU issue is still a hardware issue.
 
so if you cannot accept that, then too bad.
Why the attitude?

@ArcticWolf was simply suggesting some viable options to try to resolve your problem. Many of the suggestions mentioned have resolved similiar issue's in the past for other members!

You come here looking for help, only 2 or 3 post ever, and that's what you come back with... :rolleyes: Mind boggling !

What makes you think he cannot accept that ? He's a " Trusted Helper " for a reason ;)
 
Why the attitude?

Oops. Sorry if I sounded bad. I didn't mean to be. Was just a little put off by ArcticWolf's comment "...you're also guessing, wildly!! It could be your regional tidal patterns or our orbit of the sun too if we're playing the guessing game". Not that I just jumped onto the "hardware issue bandwagon", but I really did spent my fair share of tweaking the unit for about a year until I gave up.

Sorry @ArticWolf :)

A reflash will definitely confirm if its a hardware issue if still present. Have you done that too?

No apologies necessary bud :). The vast majority of us know what it's like to purchase an electronic device & experience problems where the answers aren't always immediately obvious, & the frustration that can cause. (And yes, sometimes still ending in defeat too :(.)

It's a shame you didn't post about this problem back when you first joined the forum, or even when the problems first started for you as there was always a chance their discussion could have lead to some form of remedy :).

You've opened a dialogue now so let's concentrate on hopefully fixing it for you :).

A reflash will definitely confirm if its a hardware issue if still present. Have you done that too?

Let us know if your issues still persist after this procedure.

Hi did anyone resolve the reboot issue? My u9 only reboots when streaming a movie with vpn on. If I stream without vpn no problem. If I stream a tv episode (45mins approx) with vpn on - no problem, its only with movies and vpn when over approx 1 hour then it reboots
 
I've had the box for about a year. 6 months ago it started to reboot itself every month or 2 so I just lived with it. At the end of May, it started to reboot itself once a week and I kept ignoring it. For the last couple of weeks, it's rebooted nightly in the middle of watching shows, so it's time that I do something about it.

I did a full reset and re-installed everything from scratch on Saturday. That didn't make any difference, it's still rebooting at least once a night.
Reboots happen in both Kodi 18.2 and in IPTV, so it's not Kodi specific.
One reboot happened when I was updating an android program (Before the rebuild).

A couple of questions:

How do I look at logs to see if I can find out what's causing this?
Has anyone else seen this or have a solution?

Thanks in advance folks.

had the same when i used the u9. only thing that worked for me was installing coreelec. and stream via coreelec instead of android. never been sure if it was a hardware or software issue.
1 disadvantage meanwhile coreelec is only supported on the u9 up to kodi 18
 
Thank you for the advice, there must be thousands of u9's out there, do they not use vpn's, there doesn't seem to be a big outcry about this rebooting issue. Is there just a small number with this problem was it a bad batch during manufacture ?
 
I have a U9-h and have not had this problem, but what you describe sounds very much like the problem I used to have on an old nexus 7 (also on android 7) android tablet. It would reboot itself midway through while I was casting a stream. What I did uncover on that tablet was that it would do this when the CPU and the ram was filled and there was no more room for the streams or running the needed system apps in the background. I solved it on that tablet by firstly, reducing the number of apps on the tablet, but also by managing my memory, cache, and system apps running in the background. I would clear cache often, and make sure that the RAM had room on it. You can check what is running in the background in the "Running apps" in the Developers option of android. Closing and disabling unused android system apps and just all round system footprint reduction helped me on that tablet. It might even be an android system app that I turned off that was the root cause for all I know.

I have used this on my MINIX x8h-plus as well as my U9-H and it served me well.
I'm not saying that this will work for you, but it might be worth a try.
Good luck !
Cheers,

Hi, thanks for the advice. Apart from stock apps I only have azire vpn, goodev volume booster, kodi and syncler. I stream via syncler. So technically there is only syncler, goodev and vpn running. As I have mentioned previously if the vpn isn't running then all works fine. btw I have tried numerous vpn's with the same result, they all cause u9 to reboot after approx 1 hour. Any background apps running I assume would only be necessary ones. I have disabled apps before and the u9 would not start, I had to factory reset and reinstall everything
 
hmm, I see. so you have started the vpn inside your U9-H settings and that seems to be the source of the problem...so far as you know. I'm going to assume it has nothing to do with the connection type,( ie. IkeV2 UDP...etc)

If you are game, try using a windows based laptop (any laptop) with a VPN then create a hotspot and connect the U9-H to the hotspot. You will get the benefit of a VPN but without the internal U9-H settings. If the U9-H does not reboot itself then that will be the smoking gun. I would use connectify to create the VPN routing on your laptop for the hotspot.

The fringe benefit is that your U9-H is free of system encryption tasks and VPN overhead.
 
Hi, thank again. What I have done is used a GLnet Beryl router with the vpn on that, and it all works great. I just find it very annoying that some people don't seem to have any bother using a vpn, it's that that bugs me. It should perform the same as the majority of users seem to have it perform. As I stated above I have a workaround, it is the thought that mine is ..broken?

Do you enter the VPN in Settings or do you use a VPN app?

I have only ever used the VPN app that is relevant to my VPN provider.
 
Yes I installed vpn via playstore on u9. On beryl it's a wireguard config file via Beryl's settings so when using beryl there is no vpn running on u9
 
Hi All, after all this time I think I have solved my u9 rebooting when using a VPN I went into developer options General - Stay Awake - On, then Apps - Background process limit - No background processes and it works. I am one happy bunny
