I have a perfect install up and running on my Dell Venue 8 Pro 5830.
Overall seems responsive and functional.
Chrome, Google Play, Youtube working fine.
Sound seems fine
Wifi is workiing, but indicator shows no signal and details show Poor
Signal even though it's getting perfect signal
Battery indicator always shows Charging, details always say 100% up to the
point the battery dies and the tablet goes dead.
Screen does not actually go off in sleep mode, just blanks out.
Occasionally pops back on by itself. kills the battery.

Are Atheros ath6kl, and the other libraries and firmware for the Dell Venue
in this release?

I'm not up to speed on deconstructing Android so It'll take me a while to
sort out.
On Linux it was the firmware and drivers in this repo
https://github.com/AdamWill/baytrail-m/tree/master/baytrail-firmware
Can't seem to enable MTP mode on the developer options so I can't get it
connected to my computer to do more in depth work,
Changing the USB Mode from Charging to MTP crashes settings and doesn't
stick.

You can check what firmware you need and
report what was missed.

I'm not able to find much info through the terminal. So far this is all I'm
getting

CPU is

Intel(R) Atom(TM) CPU Z3740D

dmesg is nothing but this error repeated. I believe this even comes up during boot

At some point during testing distro boots I had disabled xHCI in the BIOS.
Reenabled that now but it still will not allow me to select MTP in the
Developer Options.
Settings App crashes and Select USB Configuration returns to Charging.
I'm also finding now that after I leave the tablet on and plugged up all
night to charge the battery that when I come in the next day, as reported
earlier the screen is not off it's simply blanked, and even though it will
show the lock screen when I push the power button it will not recognize a
swipe on the screen. I have to force power off and back on.

I have never attempted compiling an Android kernel. It's been a very long
time since I compiled kernels for Linux.
I do know the device is capable of supporting OTG.
I will look into this further and let you know if I have any success.
I do appreciate your responses, this device is very fringe now so not
popular to support.

At some point during testing distro boots I had disabled xHCI in the BIOS.
Reenabled that now but it still will not allow me to select MTP in the
Developer Options.
Settings App crashes and Select USB Configuration returns to Charging.
I'm also finding now that after I leave the tablet on and plugged up all
night to charge the battery that when I come in the next day, as reported
earlier the screen is not off it's simply blanked, and even though it will
show the lock screen when I push the power button it will not recognize a
swipe on the screen. I have to force power off and back on.

about OTG
The only reason I was looking for MTP/OTG was to be able to access the
device from adb terminal to make it easier to debug what's missing on the

Chrome, Google Play, Youtube working fine.
Sound seems fine
Wifi is workiing, but indicator shows no signal and details show Poor

Battery indicator always shows Charging, details always say 100% up to

Occasionally pops back on by itself. kills the battery.
Are Atheros ath6kl, and the other libraries and firmware for the Dell

I have never attempted compiling an Android kernel. It's been a very long
time since I compiled kernels for Linux.
I do know the device is capable of supporting OTG.
I will look into this further and let you know if I have any success.
I do appreciate your responses, this device is very fringe now so not
popular to support.

PCI Mode is not available in this version of the Dell Venue 8 Pro 5830 BIOS.
The only options available are xHCI Mode Enable/Disabe (I've already tried
both), Enable UEFI Network Stack (for PXE), Enable USB Boot (enabled),
External USB Ports (Enabled),
So none of this changes the functionality.
When this device is running any Windows version the MTP protocol does work.
OTG Cables do work as well.

I have a perfect install up and running on my Dell Venue 8 Pro 5830.
Overall seems responsive and functional.
Chrome, Google Play, Youtube working fine.
Sound seems fine
Wifi is workiing, but indicator shows no signal and details show Poor
Signal even though it's getting perfect signal
Battery indicator always shows Charging, details always say 100% up to
the point the battery dies and the tablet goes dead.
Screen does not actually go off in sleep mode, just blanks out.
Occasionally pops back on by itself. kills the battery.
Are Atheros ath6kl, and the other libraries and firmware for the Dell
Venue in this release?

When this device is running any Windows version the MTP protocol does work.
OTG Cables do work as well.

what are you want doing? under Windows, you can use otg cables connect usb
keyboard/mouse, your tablet under windows is a host machine,
your Android phone can micro usb cable connect your tablet otg cable, your
Android phone is a client machine.

under Linux/Android, with pci xhci, the tablet always is host machine, of
course can use otg cable connect usb keyboard/mouse.
what i said "bios otg pci", the mean is the tablet can be a client machine,
tablet micro usb cable connect computer, computer is host machine.

your tablet running Windows mtp protocol work, my understand is your
tablet(Windows) micro usb cable connect other one computer(windows), can
transfer file?

PCI Mode is not available in this version of the Dell Venue 8 Pro 5830 BIOS.
The only options available are xHCI Mode Enable/Disabe (I've already tried
both), Enable UEFI Network Stack (for PXE), Enable USB Boot (enabled),
External USB Ports (Enabled),
So none of this changes the functionality.

At some point during testing distro boots I had disabled xHCI in the BIOS.
Reenabled that now but it still will not allow me to select MTP in the
Developer Options.
Settings App crashes and Select USB Configuration returns to Charging.
I'm also finding now that after I leave the tablet on and plugged up all
night to charge the battery that when I come in the next day, as reported
earlier the screen is not off it's simply blanked, and even though it will
show the lock screen when I push the power button it will not recognize a
swipe on the screen. I have to force power off and back on.

*1st - Correction - I apologize*, I have been testing several OS builds on
this tablet and I have confused issues from another OS with this thread
Wifi does work, so ADB over TCP/IP might be possible

I am trying to find a usable replacement for Windows on this tablet. I do
not want dual boot and do not want Windows on it.
But with this release of Android-x86 there are still too many issues for it
to be usable.
I was trying to troubleshoot these issues per everyone's replies, but it's
too hard to do on the tablet screen and on-screen keyboard
Then I discovered the USB port is not working while booted into Android, so
ADB and external keyboard won't work.
I will look through these suggestions more when I go back to testing again

if 4.9 and 4.15 kernel usb work, the 4.18 kernel usb port problem make be

5830. Overall seems responsive and functional.
Chrome, Google Play, Youtube working fine.
Sound seems fine
Wifi is workiing, but indicator shows no signal and details show
Poor Signal even though it's getting perfect signal
Battery indicator always shows Charging, details always say 100% up
to the point the battery dies and the tablet goes dead.
Screen does not actually go off in sleep mode, just blanks out.
Occasionally pops back on by itself. kills the battery.
Are Atheros ath6kl, and the other libraries and firmware for the
Dell Venue in this release?

Since the wifi is completely disabled because of the missing firmware or
kernel modules this will not work.
My goal was not to need MTP or ADB. I was only trying to get into the
system to help troubleshoot this and get it working.

This is what the actual hardware should be, but I still see nothing
about OTG
Post by UniCav
The only reason I was looking for MTP/OTG was to be able to access the
device from adb terminal to make it easier to debug what's missing on the
unit
adb connect ip_of_android_x86
(do it on your debug host)

Hello UniCav,

can you compile the android-x86 code yourself?

If you can, you may want to try reverting the commit, that I mentioned
here: https://groups.google.com/forum/#!topic/android-x86/jTkVo4lo-S4

I also have an Atom based device with the same battery indicator issue.
Reverting that commit and compiling the code myself, I fixed the issue.
Maybe you confirm that solution.

I gave up on Android-X86 after about a week of tinkering and started
playing with Ubuntu and Debian. Debian Stretch installed great and just
needs work on the sound and a few tweaks. I'm pretty sure you and youling
257 are right about the kernel needing to be recompiled, but it's been a
decade since I've compiled a kernel at all, I've never done
cross-compiling, and I've never done any compiling for Android. I'm
actually working on compiling 4.19.2 now on a VM and trying to learn how to
cross-compile for the Dell. If I can get a handle on it I may try doing the
Android-x86 kernel.

I have a working build. Wifi indicator and Battery Indicator are working
properly.
Sleep is not working properly. Pressing power/sleep button will put unit to
sleep, but screen backlight comes back on and runs down battery.
Tablet will not wake from sleep with any button, has to be force powered
down and rebooted.

Yes that is correct. Apologies I did not consider that is an OTG cable to the hub. I was thinking OTG cable to PC for adb programming and USB MTP mode which I am planning to test soon.
