There shouldn't be such issue with this ROM. Make sure you've followed installation instructions in the third post of this thread.

Strange behaviour, I re-installed the rom for the third time and everything is working well now. I probably did something wrong the first two times...

Thanks

Even if that is the case, why not just press the power button like rest of the people?

Most likely you've just enabled 'Settings->Developer options->Stay awake' yourself.

Could probably change that but it's not worth the effort. Different devices with different display panels can have different limitations as well (don't want to set min brightness too low so panel switches off completely).

Can you please give me any pointers regarding display brightness configuration?

Hi10 plus is annoyingly bright at night, I'd like to try change it.

/sys/class/backlight/intel_backlight/brightness is the backlight path. You can cat/echo values for testing purposes.

There's framework configs for backlight (e.g. https://github.com/CyanogenMod/android_frameworks_base/blob/cm-12.1/core/res/res/values/config.xml#L951). On prebuilt ROM like this you'd need to use apktool to decompile/recompile framework to change that.

On CyanogenMod minimum brightness is set to 10 but it actually only goes down to 29 using brightness slider. There's probably some kernel side limitation. Edit. It's actually lights HAL issue. You need to give sane default values (see https://github.com/CM-CHT/android_device_intel_cherrytrail-common/commit/9faf6a47cd51f5d446d58a1203d4631c1466f315) and recompile lights HAL.

Cool, thanks. Chuwi Hi10 Plus functions well with:

Quote

echo "0" > /sys/class/backlight/intel_backlight/brightness

For now I added a shortcut on homescreen that does this.

0 should actually disable the backlight and essentially power off the display (and it would on most devices but not this one). I've even had devices that power off display with bigger values than 10.

If/when there's another CM12.1 build, you can use lights HAL from that with Remix OS. It will allow brightness to go down to framework minimum (10). You need to decompile/recompile framework if you need to go below that.

Nandroid backups are quite large (/sdcard/TWRP/BACKUPS).

Apparently you've also installed Windows 10 on your device since you only have 7.7gb Android /data partition.

My Chuwi Hi 10 plus came with Android 5.1.1 I've flashed CM 12.1, I likes It, but the Launcher is not good for a tablet with docker. 

Then I flashed Remix OS and it's perfect. 

There is any option of Remix OS 3.0?

Great Work!

Great Work!

There's about six million third party launchers available at Play Store you can use. At least with CyanogenMod you can change the launcher unlike with Remix OS...

Like already asked and answered several times, Remix OS 3.0 (which is based on Android 6.0 Marshmallow) is not going to happen.

How to install:

  1. boot into TWRP recovery
  2. backup -> backup (create a nandroid backup of your current ROM)
  3. wipe -> advanced wipe -> wipe /system
  4. wipe -> factory reset
  5. install RemixOS-Bxxxxxxxxxx-chuwi_vi10plus.zip
  6. (install Hi10 Plus/Hi10 Pro/Hibook Pro/Hi12 patch if necessary - see FAQ below)
  7. reboot system

Hi Konsta,

Following your guide I manage to get rid of the freeze and the keyboard problems. But after using a root booster in hope to solve wifi-problems (loosing signal constantly) only problem was the speed of wify dropped significantly (only 0,5-4 mbps, normally around 26mbps). So I tryed to install the backup I made and wanted to start in all over, but after replacing the backup through TWRP recovery, my tablet wont startup again: it hangs on the Chuwi logo screen, nothing els happins. (I can still go to boot menu through power/volume down). Reinstalling recovery rom did not help, same problem.

What is the best thing to do? Instal this one through TWRP recovery: RemixOS-B2016092102-chuwi_vi10plus-Hi12-451609XXX.zip? (i guess that also doesn't fix the problem). Do you have a solution? I don't really need Remix so if SM or Lollipop is better then I will try that, Could you please point out which direction I should try?

Grtz, Richard

Did you create that nandroid backup before you disabled dm-verity? In that case you need to flash patch to disable it. You need to create 'system image' backup in TWRP (vs. usual file based backup) if you want to be able to restore to dm-verity enabled state.

Follow installation instructions in the third post of this thread. You most definitely shouldn't flash any H12 compatibility patch for your Vi10 Plus!

Thank you for your fast reply!

I created the backup simply in the TWRP menu. But now I have a bigger problem.... My brother came by and he told me he could fix it... But i guess he erased stuff because when trying to install (through TWRP) recovery, its telling us there is no OS on the device!! :(      Now my brother went home again but I am stucked with a non-working device. Nothings bricked though, still was able to put TWRP recovery to it.

I will have a look now if there is a way to reinstall official Chuwi ROM, Android 5.1 or CM 12/13. What would you suggest? Not touching the device till then,,,

Installing  RemixOS-B2016092102-chuwi_vi10plus.zip as mention in the third thread you referred to did the trick, thanks!!!

Still leaves me with the question if it is better to install Android 5.1/CM12 instead of Remix. Could this improve performance, especially Wifi?

Thanks for the great rom.

Just wanted to share an observation. Not a bug, so nothing to fix here. :-)

For some apps, I have been observing a slight shift in the touch point response. This can be overcome by going to the app settings and checking 'open in fullscreen mode'. So I am guessing this is a Remix issue.

Hi KonstaT,

thanks a lot for this ROM. I have it installed on my Hi10 Plus and it works great.

One question: I have tried to install exFAT/NTFS support on this rom based on fuse by flashable zips from XDA and TechTablets, but I can't get exfat support running
on my device. Have you tried to add exfat by chance and can give some advise or guidance? By the way it works great on your CM12 ROM but I personally would like to stick to Remix.

Really would appreciate any help here. Thanks!

I want to use Titanium Backup to restore some apps from my phone to the tablet.  I think we need root to do so.  Is this version of Remix rooted?

No, I haven't tried. Did you test this?

Yes, I tried that one and in addition also this with the following change:

...
if [ x$SECONDARY_STORAGE == x ]; then
	SECONDARY_STORAGE=/storage/sdcard1
fi
...

Both did unfortunately not work for me.

Here's a patch with lights HAL from latest CM12.1 build. This will allow setting lower minimum brightness (framework min = 10).

The lights HAL works perfectly. BUT the built in brightness slider can't go to the maximum brightness the device is capable of, which was the case before I applied the patch.
It would be great if you can patch that too.
