Hello guys,

I saw that some of you already tried reinstalling the driver with no results.
When replacing the “43430r0nvram” file, did you delete the “.txt” extension before copying?
This file should not be a text file, so you have to rename it before copying it.
First install the driver using installshield then copy the nvram file and replace it if there’s already a file.
Just rename the “43430r0nvram.txt” file included in drivers package to “43430r0nvram” (without the “.txt” extension) then copy to system folder.

Hope that will help…

Hi Marco,

I confirm you the “43430r0nvram” should have no extension, theses instructions came with drivers package from chinese letv posts, you can find the original instruction file with the drivers package but it’s in chinese language.

You should be able to install the driver with the “Setup.exe” file in the BCM_InstallShield” folder.
If it does’nt work, first be sure that you have the V200 version of the tablet (USB connector should be both black and wireless adapter is from Broadcom, on the other side V300 have a blue USB connector and a Realtek Wifi adaptor). If you have V300 version this procedure won’t help you, you problem may be a different one.

If you have V200 and setup doesn’t work, you can force the installation using “Bcm_DriverOnly” folder.
Search and run “Device Manager” from windows search bar, you should have the deveice manager windows opening.
To update the drivers you can select the Broadcom driver from devices list, right click on it and choose “update driver”
Then select “I have a disk” and browse to “Bcm_DriverOnly” folder.
The driver should be listed, select and click “OK”.
After driver is updated replace the “43430r0nvram” file
Reboot

Good luck!

Hi mooh,

I had exactly the same problems after updating Bios to 64Bits and reflashing image using this tutorial  (http://techtablets.com/forum/topic/chuwi-h10-32bit-to-64bit-upgrade-v200-hardware/)

The tablet seems to have troubles with POWER management and freeze during reboot or power off, had to force power off by pressing 30 sec.., sometimes reboot itself…
I’ve tried a lot of things but I think the problem is due to the Broadcom Wifi driver.
The last thing I tried (and that worked!) is to replace the BCM driver by using the drivers you can find in the 32bit to 64bit upgrade post.

You can Download the x64 drivers package from this link
https://drive.google.com/folderview?id=0B7UJF0mw6LjJaExLQl9wRG9WVHM&usp=sharing

unrar C106(X64)–全部驱动.rar
in WIFI folder you’ll find V200 BROADCOM drivers and a text file named “43430r0nvram.txt”

– install the driver with installshield installation files
– rename the text file to “43430r0nvram” without the “.txt” extension
– copy it to c:\windows\system32\drivers\ folder, if there’s already an existing file, replace it or renamed it before copying
– reboot

After that, no problem at all with my tablet, it works like a charm.
Standby, hibernation, reboot, power off… everything is now OK.

Let me now if it worked for you.
