Just reading up here (and getting ready to root my device).

None of the links for SuperSU Download SuperSU TWRP Zip seem to be working.

Yikes - lots of negative vibes here - i suspect i am in for some challenging times with this device.

This was meant to be an upgrade from my Tab S (especially the dual sim).

So far....

In a room where the Tab S could easily connect to wifi, the Hi9 is struggling.

Can't get it to recognize my 400gb Sandisk, nor my 200gb.

It wants me to format.

128gb Sandisk seems fine.

Groan.....
[Device Reviews and Information] uncleabubear:
128GB SD maximum.

Gearlabs ROM best solution for root imho, no need for boot loader unlock or twrp ..

Install with sp flash.
[Device Reviews and Information] shikotee:
Will check that out - thanks.

I'm simply stunned that there is a 128gb TF limit.

Both my Samsung Note 3 (released September 4, 2013) and Galaxy Tab S (released June 27, 2014) recognize my newly acquired 400gb TF without problems.

Is this a hardware limit, or a restriction that is due to a lack of development?

Hi there,

Have you found a solution yet? I'm trying every possible combination with Gearlab, LineageOS and stock ROMS with different boot images and recovery images.

I'll dump the log during the weekend!

However I found out that Gearlabs ROM v2 was more stable than Stock ROMS and Lineage felt good, but it was like upside down as demonstrated in YouTube video

PHh- Treble A - Android 8.1.0 installed

I'm glad to inform I got finally some custom ROM flashed in after all the trouble I've gone thru in the past months.

Android 8.1.0

PHh-Treble with GApps

Security patch level: September 5, 2018

Build number: treble_arm64_agS_userdebug 8.1.0 OPM6.171019 180905 test keys.

ro.modversion=OmniROM-8.1.0-20180903-Hi9Air-HOMEMADE

First I had to flash 20181122 with SP Flash Tool, then I went to TWRP and installed magisk and then wipe dalvik and cache what lead to flash Treble image for Hi9 plus,not air. Now been some hours without a crash but I'll let you guys know what happens in near future!

So glad now! Hopefully it holds! :good:

Hello!

Currently my hi9air is on GearROM v3 + TWRP + Magisk/SuperSu. And it is not stable enough. BUT, after turning off everything what uses gms module (phone, sms, etc) it became MUCH better. Literally - have got only 2 stucks-reboots yesterday.
[Device Reviews and Information] Gumka1977:
Congratulations! Now you have a better system than others;) How did you do it? I tried to flash the GSI but without success. Write some instructions (step by step), please!
[Device Reviews and Information] banch:
Oh damn! I went nuts with all these Chuwi Hi9 devices, AIR, PRO, PLUS.

WELL I bought Chuwi Hi9 AIR tablet which worked for 8 hours after it updated itself and then begun the crash and reboot atleast once in 2hr.

The device was unusable.

I tried flashing every single stock ROM from Chuwi, maybe 5 to 6 different. And every single one did that crashing. At first adups.dota application, then just random crashes going back to desktop, or pressing some other button - CRASH

I tried with 3 different versions of Gearlabs ROM, V1, V2, V3.

Tried 2 different versions of LineageOS and every single mix you can come up with mixing all those ROM with eachother to find a setup which doesn't crash the tablet.

NO LUCK

Until

Yestersay I was once again trying some ROMS what could save the situation.

And I found it! Atleast so far never been this long without crashing.

I eventually after some Treble-ROMS I found a working combination.

GHS 20181122 Hi9 AIR ROM

Then flash first TWRP 3.2.2.0

Then go recovery and install OMENROM but it got to boot loop so flashed 8.1-system-arm64-aonly-gapps-su-hi9plus.img to replace system and ****! Tablet havn't crashed a single time for 12 hours.

SO flashed Chuwi Hi9 PLUS. ROM to Chuwi Hi9 AIR device which seems too good to be true but have been running Benchmark tests almost 6hrs to but no major improvement but NOT A SINGLE CRASH for a whole time it's been up and in use
[Device Reviews and Information] trevt:
Hi Folks,

Some tips for hi9 air users.

I noticed in Battery settings it would not display app battery usage so I downloaded GSAM battery monitor from the play store. It was showing phone and wifi as being the biggest battery drainers. I enabled air plane mode but renabled wifi. I also set wifi to turn off when tablet is sleeping. Battery drain is now 0.2% per hour when in standby. I hope this helps some of you.

Cheers,

Trev

[MENTION=9625455]cherkassy[/MENTION] To try to flash Chuwi Hi9 PLUS. ROM to Chuwi Hi9 AIR iF YOU DON'T HAVE CRASH PROBLEMS like banch, i think is too risky ...

my 5 cents
[Device Reviews and Information] shikotee:
I have not yet had a chance to root this, but am hoping to give it a shot within the week.

For people who are using microsd - what format are you using?

I had mentioned previously that I could not get it to detect my 400gb microsd.

I finally freed up an old 128gb card I had, which i formatted for exFat, transferred some files, and the tablet detected it as corrupt.

I used "SD Card Formatter 5.0.1" on my Windows machine.

When I allowed the tablet to format, it did so successfully, but in Fat32.

I removed the 128, and once again installed my 400gb, and booted up the tablet.

Again, it warned me the card was corrupt, so I allowed it to format.

Now it detects the 400gb microSD, but is formatted in Fat32.

Does this tablet not support exFat microsd's?

Seems ridiculously archaic to be forced to use Fat32 (and its 4gb max file size limit).
[Device Reviews and Information] rippledrums:
I have only used a 2gb microsd with it but I tried connecting my NTFS formatted 128gb flash drive and it detected it as a corrupted SCSI drive...

Maybe the tablet's kernel doesn't have the modules to access partitions other than ext4 and FAT32. :rolleyes:
[Device Reviews and Information] amg314:
You may use Total Commander for Android with 'Microsoft exFAT-NTFS for USB-v3.1.1.0 arm64.apk' plugin (see Attachment).

The plugin allows use SD Cards formatted in exFAT-NTFS, even without having Root access.

Hello.

Is there a sign, like 4G+ in order to see the change from LTE to LTE Advanced mobile data, when the tablet is in the suitable range of a LTE Advanced network ?

Also, is there a way to check in real-time from the engineering menu or from an app if Carrier Aggregation is used inside the range of LTE advanced network and at what bandwidth ?

Our tablet is LTE advanced compatible category 6, meaning a max download speed of 300Mbps with CA at 20MHz bandwidth.

Thanks!
[Device Reviews and Information] FrenchSparda:
Damn, most of you seems to have lots of troubles with the Hi9Air..i'm using since september, mostly as replacement for my beloved Nexus 7 2013 (best tablet ever) i used in my car....and i can't really complain about it. I installed GearLabs v2 couple weeks after i got it, and only trouble i have, is the strange square area with less light on screen.

I use it with Maps, Waze, Play Music,Youtube and except some lag i didnt had on the Nexus 7 between songs when i'm using Play Music, few reboots (maybe 4-5) since i have it, i must say thats a good tablet...for the price i paid. But i miss my Nexus 7 :crying:
[Device Reviews and Information] kirk8:
how did you guys install the Hi9plus image ? could you layout the steps? did you flash via twrp or fastboot?
[Device Reviews and Information] kirk8:
could you tell me the steps(step by step would be nice)?

btw by flashing stock recovery you mean you got recovery from latest build and flashed it?
[Device Reviews and Information] Axection:
Well.. my Chuwi hi9 Air suddenly died. I recognized an abnormal behaviour at first, that each time the tablet is sleep, it goes deep sleep (hang on sleep) and must be hard restart to be working again..

And now, after the battery is low, I turn off and charged it to full, and suddenly my tablet died. I can't even go to fastboot or Fastboot EDL - it's just unrecognizable on PC.

Is there any way to fix this?
[Device Reviews and Information] BOFH2k:

No the Chuwi ROM doesn't support ExFAT as that would require paying licence fees to Microsoft...
[Device Reviews and Information] kirk8:
You might want to try that reset button on the previous pages (just read) ,

Try to flash stock ROM on it
[Device Reviews and Information] Axection:
I did press the hard reset button (under vol button) but it's still not responding, let alone turned on.

Is it possible that the tablet got short-circuited? Like.. overcharged? I once tried charged it with Oneplus 6 charger (5V 4A)

but I'm pretty sure that was not the case.
[Device Reviews and Information] Minotavrs:
Do you try exactly this

1. Download this stock [from 1st post] Stock Rom Build number O00623 release-keys 20181122

2. Open SP_Flash_Tool_v5.1728.00.000 [download it from 1st post]

3. Use the attached scatter.txt file

3b. use the MTK_AllInOne_DA.bin[1st post]

4. Press Download button

5. Connect your Chuwi to your windows machine at power on mode [in twrp in ur case]

6. Press with a needle the reset button near the volume down key

7. Wait 3 seconds until you see SP Flash Tool to connect it and downloading the stock rom...

8. Wait it until you see the verification message of Download Complete

9. Disconnect chuwi usb cable from windows machine

10. press Power on to boot your device
[Device Reviews and Information] Axection:
the problem is no 5.

my tablet is dead. It can't be charged. It can't be turned on. It can't boot into recovery, fastboot, or even EDL. It can't be detected by windows when I plugged in the USB. It's as if either the USB port or the motherboard that died. (people may called it hardbrick).

I'm quite desperated because it's almost impossible for me to return the tablet back to Chuwi :(
[Device Reviews and Information] Minotavrs:
See this... first *its for xi10 plus dont download the fw just do the above...

if not working

the last option is to try to open the tablet and remove the battery...

See this video... how to do it
[Device Reviews and Information] Axection:
I did everything mentioned and no luck :(

Last resort is manually remove battery. I haven't done this yet, but I'll try.

Weird tho the tablet dies after firmware upgrade :(
[Device Reviews and Information] kirk8:
Have you installed the correct drivers?

---------- Post added at 07:29 AM ---------- Previous post was at 07:26 AM ----------

Well I don't think it so, it'll only accept 2 amps, just like when you connect a phone rated at 2amps to a charger rated at 3.1 amps it will only charge at 2amps
[Device Reviews and Information] amg314:
The maximum charger current does not matter. The charge controller on the tablet (if it is OK) will still limit the charge current.

Controller will also not allow the battery to be "overcharged".

I see the only way to unbrick your Chuwi - using of SP Flash Tool.

Install VCOM drivers for SP Flash Tool on your PC first. Then push Download only button and after that plug unpowered tablet to PC.

Upload screenshots of SP Flash Tool screens.
[Device Reviews and Information] Axection:
But even SPFT does not detect the tablet. The windows does not detect anything. Nothing connected on Device Manager. even without drivers, it should be detected as Unknown Device, but here isn't the case.

It just stuck.

[MENTION=8948394]kirk8[/MENTION]

I download the driver here: http://techgetoz.blogspot.com/2016/08/how-to-install-mt67xx-drivers-in-windows.html

*----------------------------------------------------------------------------------------------*

Quote: "Now, when you will connect your turned off MTK device to the Windows 10 computer by USB, the device will be recognized either trough a MediaTek Preloader USB VCOM Port interface

or as a MTK USB port if it is bricked or it has bad/corrupt firmware.

The SP Flash Tool will be able to transfer the firmware to your device trough this interfaces.

Make sure you connect the device

!!!AFTER YOU PRESS the Download button in SP Flash Tool!!!!,

as the communication interface will only be alive for 2 seconds if no data is being sent."

Download to the SP Flash Tool, since the communication interface will be activated in just 2 seconds if data is not sent.

The program communicates directly with the memory chip of your device.

If this chip is OK, you should see the "MediaTek Preloader USB VCOM Port" or "MTK USB port" at SPFT screen bottom after pressing the Download button and connecting the USB cable to a turned off tablet.
[Device Reviews and Information] Axection:
I already tried this procedure three times, and I already use the driver you mentioned above. The disable driver signature, the MTK USB Port thingy, and SPFT thingy which I have to plug-in the tablet after I press Download.

But it's still same. The tablet won't respond. The SPFT doesn't move. Even pressing the hard reset button doesn't work. This is surely broken on hardware level.
[Device Reviews and Information] amg314:
To make sure that the VCOM driver is installed properly (See Picture):

0. Check USB cable)))

1. Open Device Manager.

2. Connect turned off tablet with a usb cable to PC.

3. A new section "Ports (COM & LPT)" will appear with a new device "Preloader USB VCOM Port" / "MediaTek PreLoader USB VCOM" (see Picture)

This section will be visible during about 5 seconds and after that will disappear.

On bricked tablet flash first Preloader only.

Try connect Chuwi holding Volume Up (or Down) button pressed.
[Device Reviews and Information] Axection:
0 ) I properly use the healthy USB Cable from Chuwi Hi9Air itself.

1-2-3) There's no device detected. Even with holding vol up, or vol down, or even the reset button.

Well I need to clarify that I'm very familiar with SPFT flashing because I used to have two MTK devices back then (this Chuwi is my third) and flashing soft-brick (even hardbrick EDL) was my thing back then.

This kind of brick is whole different level. Testpoint flashing / Riffbox JTag is the only one solution I haven't tried yet because I don't have the tool.
[Device Reviews and Information] Minotavrs:
Do you try to flashing to a different computer - laptop ?
[Device Reviews and Information] Axection:
I did try to another computer, and laptop but still same result, no tablet detected.

Even I tried connecting to ubuntu 16.04, 18.04, all same. no respond.

I tried using xiaomi cable (because it well known used for miflash that requires high quality cable) but still no effect.

Additional info: I remembered I already charged this tablet about 70% before it completely died. Back then, the battery indicator was still shown when I charged.

It was just suddenly died on the next day.
[Device Reviews and Information] amg314:
Until a VCOM port appears in the Device Manager, you cannot use SPFT. I do not see other tool to unbrick the tablet.

Try find other Android MTK based device (phone, tablet, video registrator, etc) and connect it to your PC. Make sure that "Ports (COM & LPT)" appears in Device Manager.

Do you see charging animation after plugging a power supply?

---------- Post added at 11:45 AM ---------- Previous post was at 11:33 AM ----------

I have tried your method. IMO, saturation level decreased. Thanks. As for stock camera problem - I use HDR Camera. It run OK!

(See Screenshots attached - left "desaturated", right - "saturated")
[Device Reviews and Information] Axection:
I tried plugging in my ZTE N986 (MTK 6589), 2013, old phone. And it's detected, includes the charging animation. Back then I used to brick this one too by hardware corrupting the emmc, but even with corrupted emmc, it's still detected, and EDL was still accessible, just unflashable (so I replaced the emmc and then testpoint flash it).

This Chuwi Hi9 cannot even be charged now. No charging animation. No battery indicator. Maybe I need some DC electricity meter to see if any electricity goes through the tablet. But that's too much I think.

I'm run out of ideas, aside of testpoint method.
[Device Reviews and Information] amg314:
You may use something like USB tester:

https://m.ru.aliexpress.com/item/32...id=726amp-LKqqICoeA4DxStLCg9DvPg1548862060963

What about "Ports (COM & LPT)" in Device Manager while connecting your old phone?
[Device Reviews and Information] Axection:
Ah... good idea. So the name is USB tester. okay I will try ordering that.

on ZTE N986, it detected as N986 while turned on, and "Mediatek Preloader USB VCOM (Android)" on COM7/8 while turned off.
[Device Reviews and Information] Axection:
Okay, I already bought the USB tester and I think I know the problem.

It's confirmed something's wrong with the power of the tablet. When I tried to charge the tablet, I got only 0.03A (yes, 2 coma behind), which is not enough to power up the tablet even for EDL or flashing (normally it's around 0.5A minimum to do so). And I assume even testpoint won't work too.

Good to say, this tablet is dead on the mobo part :(
[Device Reviews and Information] Minotavrs:
After this you have 2 options ... i dont think is motherboard issue...

1st To try to open it and fix it alone

2nd To go to service

* Maybe the USB charging interface has something wrong. Check if the USB connector on the Chuwi tablet is damaged or the pins inside are deviation, which causes adapter not matching the USB interface. In this case, you need to change a USB connector for your Chuwi

* Maybe the battery of your tablet is bad... try to remove it and replace it... if you don't want to pay for a battery do like this video to test it if motherboard is ok and charge directly from usb cable without battery.... after this buy a battery and replace it
[Device Reviews and Information] amg314:
If the battery of your Chuwi is 100% charged, then the charge current will be slightly more than zero, as in your screenshot.
[Device Reviews and Information] Axection:
haha, neither of the options I can do. Replacing parts and soldering are not my expert. I can only open the back cover, but I'm not that handful to do the operation :))

Anyway, thanks for the followup of this. At least now I know it needs physical fix to revive the tablet. Maybe I can find someone who can in my country. Not sure I'll gonna go to such extent just to fix this lil Chuwi tab.

Yeah I kind of remember full charged the tab. Hence, my initial speculation was "overcharged" caused the tab died.

[Device Reviews and Information] strawsy:
If you look back on the forum I had this same exact issue. It's a physical hardware issue. My tablet was working fine, I had not flashed it for a while and it stopped charging or being recognized by the pc. I took the battery out and charged it separately, also tried another battery and direct wired with no battery. I was going to solder a new USB connection but that is not the issue. It must be the usb controller that has failed. Wish I could use the screen for something at the least.
