anyone knows which custom ROM have tap to wake? Or how to enable tap to wake? Maybe a plug-in/mod of some sort?
[Device Reviews and Information] amg314:
Unfortunately, our tablet have no proximity sensor so it can't use apps like

Wake On Gesture/(Pro)

[Device Reviews and Information] NikosD:
He is asking for a custom ROM or app regarding tapping on screen, not gestures.

Gestures may need proximity sensor, but tapping doesn't.
[Device Reviews and Information] amg314:
By tapping you can switch screen off (having root and using special app). But, IMO, one can't switch screen on using our tablet.

Btw do you recommend the stock 0604 firmware over the 1122 one? If so, why?
[Device Reviews and Information] Gumka1977:
Gear Labs rom is cool :)

Wysłane z mojego Hi9Air przy użyciu Tapatalka
[Device Reviews and Information] amg314:
While studying colleagues notes, I did not find uniquely positive reviews on any ROM.

I personally worked with two firmwares - 0604 and 0811. I did not notice any major differences - with one significant advantage for 0604 - it has an unencrypted data section.

I will note the specifics of my tablet - I delete many pre-installed applications, including gapps (I use microG instead). I use Magisk and Xposed Framework and it's modules. As a result, the original ROM is modified (different recovery.img, boot.img, system.img, framework.jar, etc.)

Another important aspect is the priority tasks solved on the tablet. For example, I do not play games (excluding chess and solitaire), do not listen to music, do not use radio module, etc. Another user will have different priorities.

Therefore, I can not recommend 0604 for all purposes. It suits me so far. If your ROM has decrypted data area and everything works OK, there is no point in switching to 0604.

If you or someone else tell me about the advantages of some firmware (say 1122) compared to 0604, I will install it and try to remove the encryption of the data partition)))

PS I liked one of the Viber backgrounds and I used it as a desktop wallpaper for our tablet. Photo is enclosed.
[Device Reviews and Information] rippledrums:
Thank you for the detailed explanation :)

I tried installing xposed from the Magisk Repo, v90-beta3, and it boots to the system but then almost immediately soft reboots and keeps doing this in a loop.

Any suggestions without losing my data?

Two ways to uninstall Magisk Xposed module:

1. TWRP uninstaller: https://xdaforums.com/showpost.php?p=72542167&postcount=242

2. Magisk Manager Recovery Tool V2.1 ALPHA by Pzqqt https://xdaforums.com/apps/magisk/tool-magisk-manager-recovery-tool-v1-0-t3866502

You should install this *.zip in TWRP and delete Magisk Xposed module
[Device Reviews and Information] rippledrums:
Oh I just uninstalled it by deleting the module folder in /data/adb/modules

Was asking if you had any ideas why it's doing that for me?
[Device Reviews and Information] Imperial.mack:
Did that for me also. You have to manual install from twrp.
[Device Reviews and Information] amg314:
It's very interesting) - first you told us about bootloop after Xposed Framework installing, after that you delete module by hand from /data/adb.

To advise something to you we need log info: -- Install Xposed Framework once again and press disketter picture in upper right corner of the screen and upload a log file like this: /storage/emulated/0/Download/magisk_install_log_2019-05-148T10:24:36Z.log
[Device Reviews and Information] rippledrums:
Here is the Magisk install log after flashing xposed, the tablet stayed on bootloop always showing the boot animation.

Also took system logs after removing xposed if there's anything helpful there.

1. You have not previously used SuperSu.

2. Your Magisk is installed without errors (see Photo 1)

3. You have a BusyBox module installed (see Photo 2)

4. Your Magisk gives out root to your applications (see Photo 3)

USB tethering

Hi everybody,

can anyone tell me if the USB tethering is working?

I need it only to transfer files from tablet to PC, much faster than WiFi.

MIne it's not.

I've tried Descendant 2.3 and 3.0 ; and Aosp 9 v113.

I've tried to flash ( via TWRP) a 8.1 system but the tablet is in recovery.

Please if yours is working, in what system are the tablet?.

Thanks.

If I turn on the USB tethering from Settings > Network > Hotspot&tethering it doesn't work.

I got to put the "Use USB for" ( in USB Preferences ) on PTP and then turn on the tethering.

Hi everyone, there is a new project (BLISS)

Link : blissroms com

This work was produced by a team of XDA.

There is no ROM android oreo 8 (Bliss), so it is impossible to install the ROM (Bliss) android 9.

I will have to install phhusson ROMs:

1) AOSP 8.1 v31

2) AOSP 9.0 v114

then, install with TWRP the latest ROM ( Bliss-v11.9-berkeley-OFFICIAL-20190608.zip ) android 9 pie.

I will tell you if the ROM BLISS works well.
[Device Reviews and Information] LUYULKMOIO:
I tried to install the ROM BLISS, but without success.

I first installed the ROM AOSP 8.1 v31 of phhusson, then the ROM AOSP 9.0 v114, via TWRP, but there were already a lot of problems.

Then, I have installed the ROM BLISS, but there was boot loop.

Short, a lot of time lost, to try to install the backup via TWRP, but that does not work anymore.

I had to redo a clean installation via (SP_Flash_Tool), format+install, with the STOCK ROM (Update_20181122).

Someone would have a last good version of the TWRP for CHUWI Hi9 Air ?

hi amg314, Thank you for the link, but I already know, I thought there was a better current TWRP.

hi FrenchSparda, I do not intend to repeat tests with TWRP, but with (SP_Flash_Tool) for install the GSI.

It is essential, have an android ROM 8 aosp or other and a upgrade ROM android 9 aosp, to be able to install the ROM BLISS.

With the ROM stock 8 of chuwi, can not upgrade with android 9 pie, that's why it takes, use another ROM, who have android 8 et 9 from the same family.

I already test with the ROM (phhusson), but that did not work.

I intend to test with other ROMs GSI, and hoped to successfully install the ROM BLISS.

Currently, there is no blissroms ( GSI arm64 a ).

In spite of ROM (phhusson AOSP 9.0), seems promising, I intend to reinstall, when there will be version android 10 (K).

Can't remove the "no command" screen

Hello Friends,

I tried to install the TWRP recovery on my "Hi9Air" with

fastboot flash recovery recovery.img

and also with the "SP flash tool" under Windows. Both actions have ended seemingly successful. After boot to recovery I see an exclamation Point in triangle with the text "no command". In the next step I select the old recovery menu (Power On + Volume Up) and "Wipe Data / factory Reset" and also "Wipe cache partition". The next boot to recovery shows me again "no command".

Booting to TWRP with

fastboot boot recovery.img

does also not work. I see "OKAY" and the device boot to the system instead of TWRP.

What can I do? Many thanks for help.

[Device Reviews and Information] amg314:
It is difficult to comment without more detail information about your ROM and TWRP version((

The common way is stock ROM flashing using SP, then TWRP installing using SP, then rebooting to recovery using buttons (NO system reboot), next Magisk.zip flashing.

After that you will have working TWRP (maybe with a data area encryption problem((
[Device Reviews and Information] rolfn:
Thank you for your replay. I think I use already the stock ROM because the device is new and has no modifications (Version 8.0.0). As TWRP I used this one: https://androidfilehost.com/?w=files&flid=281733. Should I flash another stock ROM?

...Rolf
[Device Reviews and Information] amg314:
Hi, Rolf!

All 4(or 5)) stock ROM releases are Oreo, 8.0((

Chuwi promised Pie, but......

Every Hi9Air user have his own opinion on 'best ROM' version.

IMO, use your current ROM (if there are no problems))

As for TWRP, I use the same version. It run OK on my Hi9Air.
[Device Reviews and Information] rolfn:
Thank you for your hints. I will try to install a Pie based custom ROM (maybe "Havoc"). Installation of another stock ROM now lets me install TWRP without the "no command" problem. I come back if I see the next problems ;)
