Hi
@dig .
To factory reset try this (you said you tried but you can try again)
1. Power off your NEO U9-H [keep the power supply and display connected].
2. Press and hold the power button for approx. 6 seconds until the unit goes into recovery mode.
3. Select 'Wipe data/factory reset'
My u9 only displays splash screen then blank,.
He can't unfortunately. His device
won't advance past the initial splash screen!!
@dig focus on number 6 like
@notrui suggested and link for USB burning tool.You tried everything except USB burning tool to make work again and if you can try another pc and use usb 2.0 port on pc.
6. Connected to USB burning tool, tried many USB leads, box not recognised by program, have used burning tool before with this same setup and PC, was ok
.
I think you're confusing
@dig 's own actual post with
@notrui mate lol
. (It was dig himself that listed
number 6 as something he tried & he specifically mentions trying the USB Burning Tool
.)
Ergo, he did already try the USB Burning Tool.
@dig ,
I'd say you've posted in the correct place for your specific issue so don't worry about that
.
What
will the device do right
now? (Blue LED lit on the front & you still get the splash screen or absolutely nothing at all?) If you still have the MINIX splash screen & a blue LED it would tend to indicate all is not necessarily lost just yet
!! Additionally, if you no longer have the blue LED have you retested the PSU's voltage since that happened?
1. Try completely uninstalling the USB Burning Tool from your laptop. When you reinstall the tool
ensure that the
accompanying USB drivers are installed with it.
2. If you have an older version of the USB Burning tool, try updating it to the latest version. (Do a fresh uninstall/reinstall.)
3. If you already have the latest version of the USB Burning Tool, try uninstalling it & downgrading to an older version. (I.e. try v 2.0.6.2.) In some circumstances the latest version isn't necessarily always the best one to have. (An older version worked flawlessly for me for a long time but the more recent version has of itself caused a few problems for me recently as well.)
4. As has been pointed out, this could be an issue with specific USB ports on your laptop, anti viral software, firewalls, anti malware, the list goes on. Do you possibly have another PC or laptop you can try or kindly ask a friend/family to install the burning tool purely to allow you to flash your image? They can immediately uninstall it again afterwards if successful.
I've had this exact scenario happen with 2 of the 3 U9-H's I have access to with the devices inexplicably becoming stuck at the initial MINIX splash screen. (One has only done this once with no problems at all ever since the firmware was re-flashed. The other did it
repeatedly specifically when connected to an AVR with no other apparent cause, reason or trigger. (It was swapped around to be used as a beta test device with "other than stock firmware" & a direct to TV connection, that's also been fine since the swap around too. I really have no clue what triggers it despite seeing it well over a dozen times with that single device, all within a very short time period as well!!)
The
only way I could resolve the problem each time I experienced it was a completely fresh flash of the firmware. (I tried pretty much everything you've listed each time before resorting to flashing too.) Obviously,
you need to get that USB Burning Tool issue fixed first so that you can proceed as normal. It's a
vital link in the chain & as long as that's potentially got problems it won't matter what you do with anything else until that's first rectified. Additionally, whilst it's not a given/absolute, some users have reported that the re-flashing process would
only work with the original MINIX OTG cable, or a micro USB cable with the slightly longer 6mm connectors. Conversely, other users have also reported everyday/run of the mill micro USB "data" cables (4mm connectors) working absolutely fine as well. (It's anyone's guess what exactly causes this but with the massive array of laptops floating around out there, or pre-built/custom built desktop PC's, it does seem to be highly subjective to any given hardware. Add in the endless number of individual apps/software options individual users install on their laptops/PC's & the variables involved add up to truly staggering numbers rapidly heading for the infinite lol
.)
In your instance, there's a minimal chance it's a mix of both problems if you've tried the USB Burning Tool over & over with multiple USB cables as well.
(However, the USB Burning Tool is more likely to be what's holding you back. Are all of the micro USB cables you tried definitely
data cables & not just charging cables as well, or are they even
all of the same batch/brand/source etc.?). Ideally, the
original OTG would be your best option if you have it? Failing that, can you borrow another
quality data cable to try as well?
Let us know where you currently stand, there may still be a small glimmer of hope
