(Updated with new info) V1.16 BIOS update and Kionix sensor driver!!

[Daniel J.]

(Update 8/11-2017: It has come to my attention, that this latest v1.16 has disabled the sensor that makes the screen auto-rotate according to how the tablet screen is placed(mostly usefull when the Hi13 is used as a tablet without keyboard attached). If you need this feature(you can still manually select the orientation in windows), I recommend using BIOS v1.14, as this has fixed the issue on my own Hi13 tablet after downgrading. As of now, I don’t know when or IF Chuwi is planning on releasing a new BIOS that re-enables the sensor again).

First a Warning: Don’t attempt to flash your BIOS with this version, if you have the newer hardware revision of the Hi13 model(which uses this bios version naming: I2W6_AP135.037). And if you have doubts about how to go about flashing the bios, you probably shouldn’t do it anyways. And if you have a fault on your tablet, where the hardware is likely to blame…..get it sorted out first, before flashing. You may risk loosing your warranty, if you flash the bios first and you later send in the tablet on a warranty claim. And if you do the flashing with windows running(like me), make sure you don’t have any programs running in the background(especially antivirus and anti-malware programs, which people tend to forget/overlook).

Get the v1.16 bios download from here = http://forum.chuwi.com/thread-4709-1-1.html

Get v1.14(which I currently recommend sticking to) from either the download section on this site or Chuwi’s here = http://forum.chuwi.com/forum.php?mod=viewthread&tid=3901&extra=page%3D1%26filter%3Dtypeid%26typeid%3D62

Latest release notes:

v1.16

1. set port I2C5 pull none      Note: which is really just a description of a electrical hardware signal change and thus, does not really give you any hint about what it actually affects

 

Some of the older releases:

v1.15

1. Change G-sensor I2C port(I2C4)
2. Add pogo detect pin

v1.14

1. Hide the disabled boot options in boot override menu and BBS POPup menu.
2. Fix issue some panels can’t work normally.

After flashing from v1.14 to v1.16 myself(and rebooting the tablet). I noticed a device error(in windows device manager) with the Kionix sensor driver. However, as I didn’t check before flashing (because I didn’t notice any errors telling me about it). I can’t say for sure, if it is related to the bios flashing(maybe others can verify this for me?).  But as I could not seem to get the sensor device to accept the previous driver from the Chuwi driver package, I decided to download latest driver from Kionix’s homepage instead, which seems to have fixed the driver issue. Link = http://www.kionix.com/downloads

• And select the KXTJ9-KXCJ9-KXTJ2 Driver

 

For latest Graphics, Wifi and Bluetooth driver, I recommend downloading Intel’s Driver and Support Assistant, that scans and verify’s if your tablet uses latest released drivers from Intel. Link = https://www.intel.com/content/www/us/en/support/detect.html

 

I haven’t done any thorough testing, but after doing the Kionix driver update, everything seems to be working fine on my Hi13 tablet after the v1.16 upgrade.

How did you downgrade the BIOS?

Is it possible to use the same method like for upgrading?
