hi folks, i just received an HiBook Pro i bought as a gift. (from geekbuying, but that doesn’t really matter).

it came with 2 massive issues:

1. the screen glitches and flickers, it seems many units do that and seems related to wifi interference, aka a design flaw (more on that here http://forum.chuwi.com/thread-2688-1-1.html)
2. windows 10 is not activated and won’t activate, forcing you to buy yourself a license. (no MSDM acpi table obviously)
3. type-c port is just usb 2.0 as it is on the type-c iwork10 ultimate

i think i’ll be returning this crap ASAP

Any news about the Linuxsupport? I read this thread a couple times, but i didn’t really get whats actually working. wifi is working? And i read sth. about the sound driver, too, is it working? whats with the touchpad? Also i read nothing about bluetooth, so is it working out of the box? I’m not shure if I should buy the ezbook or not… Im a student and I need a cheap Laptop with a very long battery life… I’m using ubuntu only, I don’t want to work with windows 10… Does anyone have an advice for another device maybe? Hope this thread isnt dead, greetings from germany!

I’m still here… sorry Brad and everyone but I’m having so much work that I can barely have time to install a USB and test it, and I must confess that by now I though this would already be working after so many hours I put into with the help of everybody, but no, no wi-fi, no sound, no touch pad, and no bluetooth.

On ubuntu 16.10 the screen brightness can be adjusted out-of-the-box but that’s it. Linuxium version also nothing.

The real pain for me is the sound, it’s the only thing I can’t live to make this usable, cause wi-fi I can buy a cheap dongle, touchpad I don’t use ever (I Prefer mouse) and bluetooth I can also live without it… but without sound it’s a deal breaker to me, so I’ve been dual booting but shamefully I have to use W10 almost all the time :(((

I only hope that sooner or later full linux support (out-of-the box or not will come) at least for sound, until then I’m stuck

P.S: But when I have the time I’ll repeat every process made earlier that Brad told me to do and paste updated reports, so maybe someone might see something fixable

Again sorry for staying silent for so long, but I promise you that I won’t give up ever (that how linuxers roll), it’s just that I’m an IT freelance and sometimes there’s little to do, and sometimes there’s a lot, and keeping that balanced with a wife and kid is a lot to take in, but it’s super fun!

Best regards

An update on wireless issues with i9 and Linux.

tl;dr
Downgrade networkmanager to 1.2.5 or earlier.

Here is the best fix I know of so far for using the Cube i9 with Linux.

Download and apply the known alternative rtl8723bu driver

Check if you can scan to get a list of APs (wireless access points) using NetworkManager. A command line way is to run
nmcli device wifi list

If this command lists nothing or your gui cannot find any Access Points then check your version of NetworkManager. In Archlinux/Antergos this is
pacman -Q networkmanager

If your version of NetworkManager is later than 1.2.5 then downgrade to version 1.2.5 or earlier.

sudo pacman -S downgrade # get downgrade script if you do not have it already
sudo downgrade networkmanager # choose an earlier version and answer y to add to IgnorePkg (a setting in /etc/pacman.conf)

With regard to my patch for mainline driver rtl8xxxu, this will work without downgrading NetworkManager, however wireless throughput is slower and it does not work with all wireless Access Points. I have a few clues as to why the throughput is slower and that it is related to problem with some Access Points, so if I can find some time I will do more work on fixing this.

With regard to patch proposal, the Linux maintainer for the rtl8xxu driver wants the particular fix I applied to be tested with more devices, as the driver is for multiple Realtek USB wireless devices. I don’t have these devices. So nothing is going to happen fast. At least a process has been started.

Patch proposal rtl8xxxu driver code is now on Github at https://github.com/johnheenan/rtl8xxxu

Hi there!

when i connect more than one device to USB hub, for example mouse receiver and either  a flash drive or a ssd usb disk then wifi stops working.

Any idea why?

[Frédéric Gub]

Hey Robertson, your issue is 100% firmware. All you have to do is create a usb drive with rufus, you download the iso of wibdows 10 x64 with the microsoft tool, then on rufus you select the iso, choose GPT for UEFI then create the drive, then plug it it on the tab, press esc on boot, boot devices and USB. It should be detected (i did it on my tbook 10 as well).

For the rest well, this tablet is crap. The aluminium battery keyboard never came, some people have one but it is more or less defective they actually sold the defective ones, then they released standard leather keyboard as a replacement.

Other than that, you can’t charge the tablet troough dc while using OTG function, complmtetely absurd. The WiFi signal is ver very poor due to the all metal case, and the speakers are just lame.

I got a cube i10 for 120$ keyboard and tablet on gearbest, it has DC charging, full size USB, micro USB, kack, Mini HDMI and everything. And sincerelly, it runs way smoother than the tbook 10, thanks to the 1366×768 resolution, wich is more than enough on windows for 10.6 inch. The 2gb of ram runs at 1333mhz, and the emmc drive is actually not bad. Far better than the tbook 10

I can confirm Larry Finger’s alternative rtl8723bu driver at https://github.com/lwfinger/rtl8723bu is working again.

It was tested with the current Archlinux distro using Linux kernel 4.8.4. Since Antergos uses Archlinux, Antergos will probably work also.

Larry’s alternative driver only has a master branch so you cannot pick up a previous version from his site, if that is what is needed.

To avoid having two wirless interfaces, instead of one, it is currently necessary to edit the Makefile before running make. This is explained in README.md. Two wireless interfaces enables the hardware to act as station and access point (AP) simultaneously (called concurrent mode).

You of course need to disable the default linux driver, rtl8xxxu, by adding in to a conf file in /etc/modprobe.d, such as /etc/modprobe.d/blacklist.conf, the following line:
blacklist rtl8xxxu

As for the default mainline linux driver, rtl8xxxu, which does not work, the following lines appears with dmesg

[ 3.606634] usb 1-7: This Realtek USB WiFi dongle (0x0bda:0xb720) is untested!
[ 3.606635] usb 1-7: Please report results to [email protected]

I emailed Jes Sorensen but got no response. While the Cube i9 is clearly not using a WiFi dongle, internally the IC is connected by USB and so functions the same way as a USB dongle.

In https://www.kernel.org/doc/linux/MAINTAINERS Jes is listed as the maintainer for the Linux rtl8xxxu wireless driver. Larry Finger is lsited as the maintainer for other mainline wireless drivers.

In https://wireless.wiki.kernel.org/en/users/drivers/rtl819x rtl8xxxu is listed as multi-driver for USB for kernel 4.3+ and also as a WIP (work in progress).

I have had a sufficent look at the inner workings of both rtl8xxxu and the alternative rtl8723bu drivers to try and have a stab at finding a fix for rtl8xxxu myself. If I feel I have reached a stage when I cannot get any further with finding a fix I will email Jes Sorensen again with details of what I have tried and lodge a kernel bugzilla report. If I find a fix I will put my patched version of rtl8xxxu patch on github and send the patch to Jes and to an appropriate kernel mailing list. However the drivers are so complex and the available information about the wireless IC is so scant it is unlikely any first patch fix proposed by anyone is going to make it into the kernel without being reworked or a differerent patch used.

There is no reason to believe the rtl8xxxu driver will not eventually work for the Cube i9. The alternative rtl8723bu driver itself appears to be a continually patched version of an initial linux driver originally written by the manufacturer. For just a driver it has an incredible number of files.

For the rtl8723bu wirless IC, the rtl8xxxu driver itself uses only two .o object files generated from source code .c files, an abstracted common rtl8xxxu_core.c file and the rtl8xxxu_8723b.c file. The driver uses the heavily abstracted mac80211 wireless driver. The intention is that the mac80211 driver eventually service all wireless drivers. Such abstraction makes it easier to maintain the linux kernel and to continually build useful wireless extensions that will work with wirless drivers that use the mac80211 driver. The alternative driver has more than 80 .o object files. So maintenace will be a nightmare.

As for concurrent mode in the alternative driver, I don’t know if this was originally in the manufacturer’s driver and Larry has just decided to enable concurrent mode or not or whether concurrent mode needed extensive work. There should be no reason why rtl8xxxu should not be also enable a concurrent mode, eventually.

While this is technical and hardly of interest to those who just want a good cheap high performance tablet to work with Linux with a minimum of hassle, your best current bet might be to give Antergos a try, download the alternative driver and make sure concurrent mode is not enabled in the Makefile. If you do not have a USB to ethernet adapter or a WiFi dongle, then plugging in a mobile phone in tethered mode will do until you get the WiFi driver working, including for installation and including for fetching the alternative driver source code from github. However you may need to place the phone in tethered mode again after a reboot. Using a cheap ethernet to USB adapter is by far the least hassle method for installation.

To compile modules in Archlinux (and so also Antergos) the following packages are required: linux-headers and base-devel.

From what I’ve read there is this 19% tax that I will have to pay, no matter what. I’ve ordered a couple of things from out of EU and I always had to pay that, I just never ordered from Gearbest either, so there could be a chance that I won’t actually have to pay. But I wouldn’t bet on that.
265,00€ is a nice Deal of course, was that from Banggood? Since you said you never ordered from Gearbest. I would definitely order for that amount, even if I had to pay 50€ taxes just like you did. I think I will wait a couple of weeks and look for a nice deal and if nothing happens I will go with whatever I am feeling that day.

 

That new Wifi-controller is honestly the only thing that matters to me, the power plus I am getting is personally not worth the 80€ and the USB-C connection is not something i desperately need either, but with the new Wifi-Thing paying 80€ altogether seems like a good investment.

[Franzli]

Hi,

I haven’t ordered anything with gearbest as of yet and I’m not sure I’ve understood this properly, but some websites claim that by choosing the free Priority Germany delivery option they somehow make a special sort of delivery so that you wouldn’t have to pay extra? Though I’m not entirely sure if that was related to the regular sales tax or to extra customs charges (which wouldn’t apply for tablets anyway).

Gerneally, it makes sense to look out for a sale, recently there were a bunch of sales offers on that tablet on gearbest as well as banggood. I got mine for around 265€ (+50€ tax on arrival). As far as the comparison to the i7 Stylus is concerned, I don’t really know. I suspect that performance-wise there is not a huge difference, although if I remember correctly there are some slight differences in connectivity (I think the stylus didn’t have AC WiFi nor USB-C, and it doesn’t work with the transformer style keyboard dock if that’s a concern for you).

It’s the wifi that cause the problem, check my post at Chuwi website in forum section firmware http://forum.chuwi.com/thread-2688-1-1.html, I use wifi dongle through usb port in keyboard, and the glitch not appear again, but still waiting for official fix from Chuwi 🙂

[Mike]

Finally fixed wifi issue. Its kind of weird. Ok I dowon loaded all drivers from this site on to one USB. Then downloaded windows 10 OS download for version 10.0.10586 Build 10586. (The version I uesd after my voyo crashed was Win 10 1607 14 393.187)  I made a boot disk using rufus.exe and boot from usb. Almost everthing worked except wifi and touch screen was backwords. Then restored system to clean out all files and programs. took about 2 hours. It cam on like Brand new. every think works and so far all updates work. and no chineese on the system.The driver i am using is 1.596.12.0 . So look for Win 10 1511. Use the 64 bit home version .if wifi is still an issue look for ( Magic Driver 1.596.12.0) I tried to include the driver.

Well the driver is not in the kernel because when i update the kernel wifi stops functioning unless the driver in the kernel has a new name modprobing also reveals no driver there; i included the faulty driver in that Black list file. Its really odd the driver patch works up to 4.7.7; above that nothing Works; modprobing the driver with a lower kernel will get me the 3 wifi adapters bug. Is there a way i can neutralize the 2 surplus adapters? In a last case scenario i Will get a nano usb adapter for the wifi.

[Miki]

Did you check if wifi is OK on Android ?

 

I updated to Windows 10 and stop working on both OS’s a year ago I couldn’t solve the problem

I can’t use wifi on Android but I’m using a wifi dongle on Windows too (USB ports drain a lot of battery on this tablet)

On android I connect wifi via bluetooth (with an access point from the mobile phone), but it hangs when downloading from Google Play.

Hello Friends,

I´m new in the forum, i read all post but anything help me.

I have a Teclast X80 Power (B2N3) Dual OS with bios 3.03.

The internal microSD Card slot, not run correctly, only run on USB OTG Adapter, I need one solution for repair this bug. In other forum the people comment that this resolved upgrade the bios from Windows, but this solution not run in my case. Windows tells me that the current version is correct and the bios options are fine.

I sincerely want to solve this problem only to sell it … I’m very disappointed with the product, little RAM, ROM Little, Bad Wifi.

Regards

Well, mine is working fine so far, but i updated all the drivers first after i bought it using 3rd party software, so i didn’t check factory driver error.

Using it for downloading in public WiFi, campus life, and some programming. Heck i even using it as Oracle 9g server and XAMPP server since i need them. No faulty problem, WiFi is good, battery also good (around 8-9 hours), USB is good too.

The only trouble was when i updated the Sound driver with 3rd party driver updater, and it stopped working (fixed it with rolling back).

These directions (for Ubuntu 16.04) might work for use without an internet connection. Do it on another machine and copy to USB drive…

run these Terminal commands:
cd ~
sudo apt-get purge bcmwl-kernel-source

then download these two files on another Windows or Linux machine with Internet access and use a USB drive to copy them to your home (~) directory. You can use FTP, browser, or ‘wget’ command if using Linux:
http://mirrors.kernel.org/ubuntu/pool/main/b/b43-fwcutter/b43-fwcutter_019-2_amd64.deb
http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2
after these to files are in your home directory do this:
sudo dpkg -i b43-fwcutter_019-2_amd64.deb
tar xfvj broadcom-wl-5.100.138.tar.bz2
sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o
sudo reboot

then after reboot if WiFi is still not working run:
dmesg > dmesg_log.txt && gedit dmesg_log.txt
and post the content to http://www.pastebin.com and post the URL here.
Also post the contents of the file /etc/modprobe.d/blacklist.conf
