Is there a solution to problem with power button not waking the tablet? I had that problem after one day of owning of the device. I did the factory reset, it helped, but if problem comes back regularly... I don't feel like resetting tablet once a week, i like my devices to work normally for months/years. Only other option i came up with was to turn off the sleep mode, just force tablet to stay with turned on screen until i switch it off completely. But it is energy consuming, and not really comfortable.

September Hi9air Update on Chuwi forum

Dear all,

I guess: the last update files (4 september) for our Hi9Air from Chuwi forum ( xxxxx://forum.chuwi.com/thread-6040-1-1.html) have to be installed to update the august stock ROM ?

Someone knows the changes?

Thanks
[Device Reviews and Information] Palm Trees:
Chuwi already got back to me, replying "Hello, we are not able to release the kernel source code of Hi9 Air, it's property of the OEM factory."
[Device Reviews and Information] FrenchSparda:
bull****....whats the point to not release sources ? So, at this point we are stuck with A-system only

But, Android sources have to be public ? Due to the GPL licence, it seems so. So why are they not releasing it ?
[Device Reviews and Information] Palm Trees:
Well, then ask Chuwi who their OEM is and contact that OEM (probably the same one that produces all the Helio X20 tablets for Alldocube, Teclast, Chuwi etc.).

If the OEM tells Chuwi "Nah, we're not going to give you the kernel source" what can they do about it? Nothing.
[Device Reviews and Information] Alberto96:
Well in China they are not forced to comply with GPL licenses and such, reason why many chinese companies don't mind about releasing anything.

techain ( http://www.techain.cn/ ) should be the OEM FYI.
[Device Reviews and Information] FrenchSparda:
Lost cause :D
[Device Reviews and Information] NikosD:
All of the diagnostic SW I have run on the device shows me the manufacturer as "Lephone"

It's a Chinese company, but I don't know if Lephone is the OEM.
[Device Reviews and Information] FrenchSparda:
I just flashed GearLabsV3 and i had that error message while sending files. Is there a problem ? Is it "dangerous" ? (I come from latest August stock ROM)
[Device Reviews and Information] Alberto96:
It is just fine :)
[Device Reviews and Information] strawsy:
It still goes through with that error message. Did yours actually boot up? I wish I could get mine to not boot loop. I'm about to give up. I've tried flashing about 15 times now and get boot loop every single time.
[Device Reviews and Information] FrenchSparda:
After flashing, i thought it was stuck, but it wasnt, it rebooted one time, then i waited 5 minutes , then installation process began. Great ROM, smoother, rooted. Such a great work. Thanks to [MENTION=2386505]Alberto96[/MENTION], KUTGW
[Device Reviews and Information] strawsy:
Can you tell me your process?
[Device Reviews and Information] FrenchSparda:
1: i backup NVRAM

2: flashing stock ROM with SP flash tool

3 : reboot and setting Android

4 : lets try Gearlabs ROM...

5: so, reboot on bootloader

6: unlocking bootloader

7: flashing boot.img, then system.img

8: reboot...it rebooted once, while i thought it was stuck, then, i waited 5 good minutes.....and voila, setting Android

9 : very smooth ROM

10: Merci [MENTION=2386505]Alberto96[/MENTION] ;)

"Pay attention to :The OTA has been updated to the latest version" I don't know whether that means this is just a general update or it has updated the Wireless Update App which is still version 5.14, as I have not got anything OTA for a long time.

Fun and games with this update!

I installed over Stock Rom Build number O00623 release-keys 20180809

First boot it asked for a password which I didn't know and my keyboard, gboard kept crashing anyway.

From stock recovery I did a factory reset.

Restored backup of tablet.

Can't find any changes except Play Store not certified.

Let's hope OTA updates are fixed!

Anyone with a major bug could let me know and I'll test it out. :laugh:

Another response from Chuwi regarding the kernel source of the Hi9 Air: "It's the gold goose of the OEM factory, they won't publish it. We can't do much about it. Sorry"

[Device Reviews and Information] stab244:
Is there a way to install magisk after flashing a treble image or will I need to wait for a twrp port?

Also does anyone have any issue with it locking up and requiring a force reboot? Will using a treble image help?

Did you order your Chuwi from Gearbest? If so. How long took it from place order to dispatch and arrive? I ordered mine on May 03, 2018 but still no progress :crying:
[Device Reviews and Information] uncleabubear:
We are waiting for the stock rom, if you have got a boot.img you can install magisk
[Device Reviews and Information] THFourteen:
I don’t think gearbest have any stock. Banggood were the official launch partner and they had more orders than they had stock. I ordered mine 23 April and it only just shipped today.
[Device Reviews and Information] stab244:
Mine was ordered from banggood when it was $200 for preorder. Shipped May 10th and arrived May 22nd. I'm on the east coast about 20 miles from the Oakland port that it arrived at though.
[Device Reviews and Information] uncleabubear:
Cases

I have found the following cases actually made for the Chuwi Hi9 Air.

I have ordered the first one from aliexpress. They are both about US12.50 free delivery. The first one is the standard design for Chinese tablets with no support for auto wake/sleep.

The second one is the other common design, which I don't like as you can't swipe across the edge of the screen.

PU Leather Folding Stand Case Cover for 10.1 Inch CHUWI Hi9 Air Tablet

https://m.banggood.com/PU-Leather-F...WI-Hi9-Air-Tablet-p-1299573.html?rmmds=search

I am like you, I don’t like those generic leather cases that are bulky and cover the tablet bezels!
[Device Reviews and Information] uncleabubear:
Yes that’s the same one only more expensive [emoji28]Lol
[Device Reviews and Information] stab244:
I tried moving a magnet across the front of the tablet and it doesn't seem to have a magnetic switch at all. Something I'll just have to get used to I guess.
[Device Reviews and Information] 7inchTab:
Well my order from BG of 4/15 finally shipped

So my order for the tab finally shipped and I am getting the generic pu case from them with their $10 coupon for $5

It, unlike the tab, shipped the next day. I'll see which one gets here to Colorado first. Cheers!
[Device Reviews and Information] Ranomez:
Can someone please check if Vulkan support is there?

The GPU does support it but it depends whether or not they decided to include the support or not on the software side.

I don't have this tablet but I'm interested and watching how things go.
[Device Reviews and Information] thecoolkid:
Just checked. YES, it does support Vulcan API.
[Device Reviews and Information] THFourteen:
Can anyone recommend a generic tempered glass screen protector for this size of tablet? Ideally something available in the UK so i don't have to wait for banggood to ship it.

Seems like the pre applied one is rubbish.

Although having said that, my tablet probably won't arrive for another ten days anyway.
[Device Reviews and Information] Ranomez:
Nice, thanks a lot.

screen mirroring

I can not find the transmit function and therefore does not allow me to duplicate the screen on the smartv with anycastview. I doubt that I miss some system setting. Can anyone tell me how to do it?
[Device Reviews and Information] richardlittlewood:
I've got exactly the same issue. Would like to know whether to return it or not.
[Device Reviews and Information] fasty:
I had a similar problem, but it seems only to occur if a microSD card is inserted. If I keep the card out, it behaves OK.

I wonder if you are using microSD card...
[Device Reviews and Information] Fredoslaw:
I am (microSD and two SIM cards). If problem recurs, I'll try running it without one. You had to factory reset first, or simply removing card solved the problem?
[Device Reviews and Information] fasty:
I had to factory-reset, it was the only way I knew how to restart. Very annoying.

Not much faith in Chuwi!
[Device Reviews and Information] R@mpage:

[Device Reviews and Information] Hummerschmidt:
thx

Wow, it worked for me, thank you!
[Device Reviews and Information] fasty:
It looks like the presence of the SD card induces this fault that can only be fixed with factory reset.

I'd be interested in other folks opinions about this. Might it be fixed in software? I want to use SD card to store music and moves, but it's useless if it means factory reset every week!

Constant crashes

Hello! I ordered Chuwi Hi9 Air to my mother as her old Cube Talk9X U64G doesn´t allow to use banking software any more as it runs android 5.1 so I thought I could replace the old machine with a brand new Chuwi Hi9 Air and I received this tablet yesterday but oh shiet.

Its constantly crashing and I´m due to deliver tablet to my mother in 6hrs as she doesn´t live anywhere close me so it would take 500km round trip to get this device to her if I can´t fix this by that time.

I tried to look all over the files manager to find any error logs and pretty much only one I could find was:

/Chuwi Hi9 Air/Android/data/com.adups.fota/files/crash/crash-2018-10-13-11-00-55-1539417655187.txt but whenever I try top open that file tablet crashes always. I managed to get a picture of what the .txt file has inside and I´ll add that to this thread aswell.

[IMG="Error LOG"]https://drive.google.com/open?id=0B6M3Ww7BM026ZmlEQnJySkhYenBhSWpmZXppX0pldDBwWmpz[/IMG]

I am in a hurry, kinda, and I really would appreciate if someone could point me whats the problem and how to fix it. I rather do this with plenty of time but she is visiting me only today and for the next 6 hours so im in a rush...

I´d hope if someone can help me out!

Sincerely,

Banch
[Device Reviews and Information] Hummerschmidt:
May be we should ask tech support...

Encryption ----> Removing??

Is it possible to remove the encryption with the method mentioned here: [click on the word 'here']

Steps modified per above URL:

Download the August Stock Rom

Transfer the August Stock ROM to the Chuwi Hi9 Air

Open TWRP (assuming you have 'OEM unlocked' the bootloader and flashed TWRP with 'fastboot'

When It asks for password, cancel it.

Click "Read Only" button.

Install the August Stock ROM

Reboot

The OS may misbehave.

Open TWRP again. & Boom! No encryption password. (the post claims ...)

Connect to PC and copy the Important data.

Flash Any ROM now.

Any comments (especially from @Alberto96) are greatly appreciated!
[Device Reviews and Information] Alberto96:
If it works, proper or not that is, go ahead and do it. ;)
[Device Reviews and Information] johnp2343:
So, you don't think there is a danger of bricking the Chuwi?? :( :confused:
[Device Reviews and Information] Alberto96:
Lucky for you this device is unbrickable, SP Flash Tool will always save you in case of a disaster.
[Device Reviews and Information] johnp2343:
Thanks.

Good to know (though I've talked to a guy who bricked his by using the SP flash tool and ticking "Format" instead of "Download" - it's unresponsive - or so he claims...)

I'll report back - wish me luck :fingers-crossed:
[Device Reviews and Information] FrenchSparda:
I noticed today that my screen is also "brighter" in the middle, rectangular shape, so difficult to explain..

Did you sent it back ?
[Device Reviews and Information] Alberto96:
That's a voluntary brick, "Format All" is an option that has never been recommended in any case, so if you choose it, even just by mistake, then you are in search for this bad sensation :) (thus complains related to this will never be accepted)
[Device Reviews and Information] uncleabubear:
It's more like a roof tile than a brick!
[Device Reviews and Information] Alberto96:
Hahaha nice one xD
[Device Reviews and Information] johnp2343:
Then again, roof tiles do a lot of a damage as well ... :rolleyes: :cyclops:

Anyway, thanks to both of you :laugh:

[UPDATE]

Haven't had the cojones yet to try it, still figuring out how to back up the device without root ...

data partition encrypted???

Any update on this situation? I need to Backup ASAP!! Drowning over here. Gearlabs v3 is fantastic! twrp loads but no data partition access.

And/Or Does anyone have a recommendation for an alternative backup? hopefully as solid as twrp. Yes i own Titanium backup already but i really like the ghost copies twrp makes.

Thanks in advance!

Hi, I have twrp installed and my device rooted. I have two questions for the device:

First, is it possible to install via twrp from the sd-card like i installed root? I want to install the Arise Soundsystem.

Second, can I get rid of Google photo and assign another app as default gallery-app? I found nowhere how to assign a different standard-app.

Thank you

[Device Reviews and Information] amg314:
1. You can choose external_sd as origin of any_install.zip in TWRP

2. There is no problem to use any gallery as default (I use QuickPic). Settings --> Apps --> QuickPic --> Open by default (edit) --> Open supported links. You can also freeze Google photo or remove it))

X23?

Hi, I wonder if anyone here has got the X23 variant? gearbest sells it and now it is actually even slightly cheaper (176 vs 178 USD) https://www.gearbest.com/phone-call-tablets/pp_009177959044.html?wid=1433363 than the X20. If you have it - does it have exactly same build of ROM as X20? X23 is just overclocked/binned version of X20 so in theory there is no need to have different build of the ROM.

BTW some articles say the difference is only 200MHz - 2.1GHz vs 2.3 GHz e.g. here while chuwi air9 X23 upgrade articles claim it is 1.85 vs 2.3GHz
[Device Reviews and Information] uncleabubear:
It is one and the same machine. There is only one Hi9 Air to my knowledge.
[Device Reviews and Information] fanoush:
Can you explain what you are trying to say? You dispute that there are newer Hi9 Air tablets with X23 instead of X20? Or are you simply answering my question that the ROM is the same for both?
[Device Reviews and Information] uncleabubear:
To avoid any confusion, these are the Chuwi Hi9 Tablets

Hi9 8.4 Inch MTK8173 2 GHz

Hi9 Air 10.1 Inch Helio X20 (X23) 2.1 GHz LTE

Hi9 Pro 8.4 Inch Helio X20 (X23) 2.1 GHz LTE

Hi9 Plus 10.8 Inch Helio X27 2.7 GHz LTE

also

HiPad 10.1 Inch Helio X27 2.7 GHz

From https://en.wikichip.org/wiki/mediatek/helio/mt6797d

"The Helio X23 is identical to Helio X20 with the additional support for dual-camera setup and MiraVision's EnergySmart Screen technology", as found in the Hi9 Air.
[Device Reviews and Information] fanoush:
You quoted me twice and actually never answered any of my questions . And both times what you wrote was mostly unrelated to the part you quoted :)
[Device Reviews and Information] uncleabubear:
Perhaps you didn't understand from my replies there is one model, if the cpu is a different revision it will use the same rom. The performance difference will be negligible.
[Device Reviews and Information] Opmovers:
Hear that? Its the world smallest violin, playing just for you. No not in this case. Twrp worked fine in gearlabs 1 & 2. It has absolutely nothing to do with my device And everything to do with software.

Any updates???
[Device Reviews and Information] fanoush:
Same model but two variants, gearbest sells both for different price and you can pick whether you want X20 or X23. X23 was more expensive previously but currently it is $5 cheaper. What you later replied to this did not add anything new or informative, it was just confusing. As for same/different ROM I am also guessing it is same ROM, I was just interested for confirmation and/or additional experience from those who really have X23 variant in hand.

I noticed the encryption issue was present prior to gearlabs v3 if the timeline is correct. I would like to mention that, on my device, the encryption issue only started after upgrading to v3. twrp on v1 and v2 worked just fine on same device.

hope that helps.

Good luck!

It is related to the August 2018 update, encryption has been forced by CHUWI (or well, techain) to meet Google GMS certification requirements and I won't remove it.

I am almost in tear's right now. Is downgrading to GLV2 the only way i'll get to enjoy Nandroid backups on this F$%K!NG cutting board i call chuwi???

Has anyone created a successful Nandroid backup while running "latest versions" of either stock or gearlabs?

FML!
[Device Reviews and Information] amg314:
This is a rhetorical question))
[Device Reviews and Information] Opmovers:
AMG314 are you insinuating that you have successfully created a nandroid backup of a hi9air running either stock v3 or gearlabs v3? My question was not rhetorical. In fact it was very literal! I NEED A NANDROID BACKUP. I only rely on Nandroid backups. Anything less is inefficient. Not being able to backup my data partition is a very big problem for me.

I am reaching out to the xda community to find a solution because i am unable too.

If you got one, speak up. If not, then stfu :) Cheers!
