Hi Nikaiako, I tried this rom as well, but with the 20180801 ROM and it did not work. Not sure if I also need an old vendor for the CWI532 old device.

Hi Christos,

I went into dev options, I have no screen test option, only two options for the input to show taps (a circle is shown where the tap happens) and the second more interesting is to show the draw of the touch and the coordinated (it leaves a line on the screen if I slide the finger on the screen and at the top I can see he coordinates of the touch input).

With the second option I could see the tablet works on the upper part for about 900px and at the bottom as well for 900px ... but not in the middle.

I will try to capture these as screesnhots or video and post them here (travelling now for 2-3 weeks without the tablet).
[Android General] KilgoreT:
It's time to change my fairy good opinion about Hi9 Pro. Let it be also a WARNING to all owners. Be extra careful with this tablet! Digitizer is very fragile.

This is the whole story: I took my Chuwi as a gps navigation for a long car trip. After a few wrong turns I realized that gps is spotty and totally loses connection at random. When I stayed outdoors reception seemed to be decent. But in car - especially when making a turns - gps got lost now and then. After testing all settings possible (and I have a lot of experience with gps devices) I tried one more thing: I pressed pretty lightly top part of the tablet to check if this is not some loose antenna connector. This slight pressure broke my digitizer.

Now I learn that I can't buy this part except for some eBay British seller who offers half price of new tablet. Just be careful! Maybe cheap phone and glasses are better solution than modern tablets. I never ever broke my phone.
[Android General] nikaiako:
Hi Kelu, I guess it is the boot.img that is responsible for the proper work of a touchscreen, regardless of the vendor.img version.

I suggested that you tried this boot.img taken from CWI532 that had 20180801 fw out of the box. Since this one also proved to be useless for you then I have no idea what else can be done. Sorry.
[Android General] Bingley:
Yep, I emailed support and they, in broken English, inferred that 9.0 is not happening as promised, I followed up asking for clarification and have not received a reply. Shame.
[Android General] Diomorgan:
I really hope in a nice custom rom, those chuwi tablets are so common due to te low price and "pretty hugh specification".
[Android General] Neuromancer:
Which are the correct and working ADB drivers for Hi9 Pro? I downloaded one from their official forum, but it doesn't work. All I get is

So at this point, I can't even use MyPhoneExplorer via USB, or make a backup.
[Android General] nikaiako:
I use this one http://adb.clockworkmod.com/
[Android General] amg314:
If you have problems with USB drivers, try modify *.inf file:

0. Kill adb process using Process Explorer

1. Plug your device to PC, open Device Manager

2. You should see something like "Android Composite ADB Interface" or "Unknown Device"

3. Click on it with right mouse button and choose Properties.

4. Copy ID to clipboard: USB\VID_XXXX&PID_XXXX&MI_XX\X&XXXXXXXX&X&XXXX trunscate it to USB\VID_XXXX&PID_XXXX&MI_XX .

5. Find *.inf file in your USB drivers directory and add to it following 3 lines:

;Your_Dev_Name (Hi9 Pro))

%SingleAdbInterface% = USB_Install, USB\VID_XXXX&PID_XXXX

%CompositeAdbInterface% = USB_Install, USB\VID_XXXX&PID_XXXX&MI_XX

and save this file.

6. In Device Manager choose update Android Composite ADB Interface driver from your USB drivers directory.

[Android General] Neuromancer:
Thanks both, I was able to make it work (the ADB part). So, the ADB commands from the shell are functioning, I can use MyPhoneExplorer, but Helium backup still seems to have issues.

On the tablet, the dialog box says "Waiting for the Helium Desktop application to enable application backup on your Android." (after connecting it to the USB). The desktop app is running at that time, but nothing changes there.
[Android General] amg314:
Helium plugin for Chrome (and Opera) browser may "help" your PC))

Origin: 4pda
[Android General] Neuromancer:
Actually, I don't use either of those browsers. :D

Come to think of it... Is it any different if I just use "adb backup -all -system" instead of Helium? Will I get to restore apps and settings this way as well?

One more thing... I've noticed on some screenshots on this forum that others also have "Battery usage data isn't available" displayed in settings, where the usage by app should be. Is this some Chuwi-related "feature" that can't be fixed? I had the same issue on Hi8 SE, and now on Hi9 Pro.
[Android General] amg314:
IMO, Nandroid backup solve most problems.

The best way to know if you could restore apps/data is a test_app experiment. Install test app first.

Then:

adb backup -f path/to/test_backup.ab -apk test_app_name.of.package

Kill test app on your device.

adb restore path/to/test_backup.ab
[Android General] Neuromancer:
Regarding the battery usage stats issue... is it possible the manufacturer just misconfigured relevant permissions for Settings (or for whichever element is doing this as "stock")?

Namely, I came across GSam Battery Monitor, and issued the "adb shell pm grant com.gsamlabs.bbm android.permission.BATTERY_STATS" command to enable the app show detailed battery usage per app. It worked.

So my question here would be -- should this command also be issued on a certain system app (and if so, which one), so that Settings would display detailed battery usage as with all other Android devices I used before?

And the other two bugs I came across (with workarounds):

- Keyboard stops making sounds while typing, after each reboot or shutdown. (For a workaround, I go to GBoard - Preferences, and turn "Sound on keypress" off and on again). I encountered on Hi8 SE as well.

- No sound in FM Radio if Hi-Fi Mode (under Sound - Sound enhancement) is turned on.
[Android General] NikosD:
You are a real Neuromancer, at least for me.

I had given up trying to solve my Radio FM issue and I thought it was a hardware bug, described here along with its risky hardware based solution:

https://xdaforums.com/showthread.php?p=76688397

But probably it's actually a software bug or feature (the kind version) as you mentioned in your post.

Now my Radio FM app works, just by disabling the Hi-Fi setting!

Using a hands free cable for antenna (mandatory) you can also hear radio from the speaker instead of the cable or even from a bluetooth headset.

Very nice.

But in order to help you, maybe you could take the risk and imply the procedure described in the above post in order to fix or "fix" the radio issue in hardware.

Meaning that I don't really know if it's a hardware bug which could be resolved this way or someone just accidentally put the Hi-Fi setting to Off and fixed the problem!
[Android General] abbots:
hi there. new here, I'm thinking of buying Chuwi hi9 Pro, looking at various description, it lists either X20 or X23 - I guess I want X23 ?

are both types available, or, is X20 original specs, and, current devices are all X23 ?

thanks for any advice
[Android General] jackspratt:
The X23 is available for US$110 (may not include GST) at Banggood at the moment - get in quick.

[Android General] Neuromancer:
Just wondering, how come this device (and I remember it was the same with Hi8 SE) has two update points in Settings?

One is Settings / System / System Update

and another one at Settings / System / About Tablet / Wireless Update
[Android General] NikosD:
I thought that Wireless updates are for security updates only, but the system updates are for the whole ROM.
[Android General] Vihru:
i think this tablet is dead? no any new roms or anything?
[Android General] NikosD:
Is there any new ROM for Hi9 Air or Hi9 Plus ?
[Android General] amg314:
Answer 'No' for Air, and I see nothing wrong with that. My old tablet works fine under KitKat 4.4.2 Moreover, ROM on it is less buggy than on my new Air.

The 'new version' does not automatically mean the 'better version'

What are new useful features of Oreo? Split screen? That's funny.
[Android General] Stremon:
Hey guys, does any of you have an issue with this tablet being stuck at max screen brightness?

The tablet is brand new, with last firmware.

The brightness doesn't change at all when I move the brightness slider, and there is no auto brightness.

It just makes it impossible to use at night.
[Android General] Vihru:
any gsi rom that makes hi9 pro faster?
[Android General] abbots:
just received new Hi9 Pro - X23 red button CWI 532, A 8.0.0

Build Number 000623 release keys OGS 20181226

reading through this thread, so, I should install the updated Chuwi build ?

CHUWI_Hi9Pro_backup_15_06_19_NEW_public ?

what with? SP Flash Tool ? Miracle Thunder ? fastboot ?

thanks for any help and suggestions, tablet working OK
[Android General] jackspratt:
No problem here with the brightness control.

In fact, the only issue I have had so far is the discovery that the screen glass seems to be quite fragile. I handle all my electronics with kid gloves, but have still managed to create a 2-3cm crack in the bottom left hand corner - this is despite the factory fitted screen protector.

Fortunately, it has not thusfar affected performance ie the screen is still 100%.

So be very careful about applying any pressure to the screen.
[Android General] Vihru:
where is that kind of firmware?
[Android General] abbots:
There is a link earlier here, think around page 61/62, this fware, and another build with recovery I think,?
[Android General] Vihru:
i have red button but older tablet.. any info will it work?
[Android General] Stremon:
Thanks, I will be very careful the screen looks indeed fragile :)

Which model do you have?

Do you have a button for auto brightness?

On my rom strangely there is no auto brightness setting, it even seems like there is no light sensor in the top.

Does it change the brightness when you move the brightness slider?

Mine does nothing :rolleyes:

Edit: I think my brightness problem might be a rom bug, I just flashed TWRP and the brightness setting is working perfecty in it...

It's really strange, the tablet is brand new and last official firmware update.

Edit2: indeed it's a rom issue, the brightness slider doesn't do anything on my rom (OGS JP 20190808), but the brightness does change if I use the app called "RootDim" to force the brightness.

Does anybody has a rom/backup of a working rom for the CWI532 model?

I guess my rom is for japan (JP) since I live here, and I know most japanese specific roms are really bad.

I would love to install an international rom instead if someone kindly provide one :highfive:

Thanks :D
[Android General] NikosD:
Never heard this problem before, for Hi9 Pro.

But in Hi9 Air thread here in XDA, I think there was a time that they had a similar issue.

Take a look at the first posts there, for a workaround.
[Android General] Neuromancer:
I have the same, working more or less fine (except for the minor bugs I reported earlier), so I'd like to know what the new build brings?

Also, the last line on the About Tablet sheet says "Custom build version ... alps-m-o0.mp1". Do you guys have this too, or is it because I uninstalled (via adb) some of the things I don't need?
[Android General] abbots:
I also have Custom build version alps mp o0 mp1 line

curious, what did you dump, maybe I also don't need that?

---------- Post added at 06:31 AM ---------- Previous post was at 06:26 AM ----------

Ouch, sorry to hear. I better get a case before soon... Any suggestions for a good case,?
[Android General] Stremon:
Really nice info, it seems to be the exact same issue indeed.

Thank you very much, I will try the fix tonight :D

Edit: on a side note, this tablet screen touch sensitivity is very weak, it often misses when I touch it, and my active capacitive stylus doesn't work well with it (it works perfectly with all my other cheap chinese tablets/phones).

Is there a way to increase this sensitivity?
[Android General] NikosD:
Yes, exactly the same here.

No problem here, but maybe because my needs are not too high and I don't have a Stylus.

I have removed the screen protector, not really sure if it helps or really matters.
[Android General] Stremon:
Yeah for normal use it seems to work fine I guess.

I also wondered about the screen protector, but peeling it a bit off didn't change the sensitivity.

I saw from one review of the tablet that the guy has the same issue than me.

Maybe it's a firmware issue too?

Will try to flash another rom and see how it goes.
[Android General] Stremon:
The trick did work perfectly, now the screen brightness level is working great! thanks again for the help :D
[Android General] Neuromancer:
Chrome

You Tube

Duo

Google Drive

Google

Google Maps

Google Videos and TV (or whatever it's called)

Google Music (or whatever it's called)

I think that's about it.
[Android General] Stremon:
Does any of you know how to force the tablet to go into download mode for SP Flash Tool?

Since I installed TWRP, it doesn't seem to want to boot into it.
[Android General] amg314:
SP Flash Tool have nothing common with TWRP, because it run on switched off device.

Before start working with SP Flash Tool you need install drivers correctly

https://xdaforums.com/showthread.php?t=1982587
[Android General] Stremon:
Thanks, actually I was doing it wrong, I was plugging in the tablet before pushing the download button, and apparently the tablet was staying in download mode for only few seconds.

Connecting it after pushing the button worked perfectly :silly:
[Android General] Stremon:
damn, I saved my stock rom to be sure to be able to go back, but when I'm trying to restore it, it says "status_partition _not_found", and I can't find what's wrong.

does anybody has any idea of what I might be doing wrong?

couldn't find any info online.

Edit: After hours of search, I finally found the issue, in the scatter file of my save it was written PRELOADER instead of preloader. seems like Miracle Thunder didn't format it properly...
[Android General] Stremon:
So after testing the other roms and coming back to my original rom, I can say my tablet Japanese rom is actually better, mainly the tablet has a better heat management (every other ones I tried are heating like crazy on any heavy task).

I'm not sure Android itself is updated tho.

The ROM date is 20190808, and the Android security update is 20181005.

The tablet model is the more recent red button model.

I got the full working backup, I can share it if you want.
[Android General] jackspratt:
The security update date of 5 October 2018 is the same as my stock, standard tablet - red button, X23 version.
[Android General] dvdfreak:
Kindly share the ROM. Thanks
[Android General] nikaiako:
Hi Stremon! It would be really great if you provide a link to the full working backup you've mentioned.

I'm on a rooted Hi-9+ and got a wireless update. I downloaded to install later because I'm rooted and figure I must go back to stock and re-lock the bootloader to update, unless I can figure out how to flash onto my rooted rom. I can't find the downloaded file to look at. Anyone have any idea how to locate it? I tried searching for large files with ES file explorer, but no luck. It's 1.08 gb so it should be easy to find but no. Any help appreciated, thanks johnm Also the file has a Chinese name so searching that way didn't help

Hello there.

Do we know what is the latest official ROM version for Hi9 Pro ?

From Chuwi or other forums or recent buys revealing a new ROM.

And the date of latest security update, too.

Also, what is the latest TWRP recovery for Hi9 Pro and has anyone managed to install NFOUND's exclusive TWRP patch on Hi9 Pro TWRP ?

https://androidfilehost.com/?fid=11410963190603893124

Thanks!
[Android General] Neuromancer:
Mine's still the same as it has been for a while:

Both System Update and Wireless Update say it's up-to-date.
[Android General] NikosD:
I have exactly the same.

It's rock stable (very few occasional unwanted reboots, but that could be software besides ROM) but the security update is more than 1 year old.

What about recovery ?

Are you still with stock ?
[Android General] Neuromancer:
Yep, still stock all the way, I haven't had the time to tinker with it too much. Also stable while using it, and it usually eats steadily around 2-3% of battery overnight on standby, when idle and offline, so it's quite good actually.
[Android General] nikaiako:
Hi Nikos! I use a hybrid ROM currently consisting of the boot and vendor from 20180801, and the rest taken from the ROM which Chuwi published on their official page for the devices "after serial number 201901" as they put it. I think this is the latest one.

As for the TWRP exclusive from NFound, I use it since its creation on my zte axon 7 mini phone, where I found it quite useful because of a number of issues connected to its snapdragon processor and a possibility to quickly turn to the edl mode when it is impossible to do so by other means. As for our Chuwi, I haven't found this twrp exclusive patch relevant in any way.
[Android General] NikosD:
I think it was you that guided me to install the same hybrid ROM, although I don't remember anything regarding serial number.

I would like to try it but i couldn't install it using unofficial TWRP 3.2.3 from Infect_Ed.

I have an encrypted partition and I get some errors while trying to install it, although in the end, it says that it installed successfully, but it doesn't.

Could you try exclusive from NFOUND on our tablet ?

Thanks!
[Android General] nikaiako:
I just tried, and please tell everyone not to try doing this!

I also have an encrypted partition. However, it installed successfully at once. And then there a nightmare happenned: first, distorted screen with several artefacts, then running lines, and in the end I got my screen divided into two parts, black and grey. I don't want to try it again. I uninstalled it ASAP, here is an uninstaller in a case someone needs it. (just flash it via twrp).
[Android General] nikaiako:
Please take a look at the build number of your hybrid ROM - I think it is 20181226. At the same time Chuwi's official ROM which I use now has a little bit different build number: 20181220
[Android General] NikosD:
Sorry about that.

But how come you managed to install it, since you have an encrypted partition like me ?

What exact image of TWRP have you installed and by whom ?

You are right.

What are the differences between them ?

And how come the 20/12/2019 is newer than 26/12/2019 ?
[Android General] nikaiako:
I don't know. This "twrp exclusive" is a real thing-in-itself., its behaviour surprised me a few times on my axon 7 phone.. Logs seemed to show that it was installed, and a number of new menu items appeared, just like on my phone. Then I tried to apply the new skin, and all went wrong. I use twrp from Infect_ed.

It is a guess, and the reason is the title on the downloading page: "HI9PRO 20190105_o OGS.rar". Inside that rar file you find this notorious 20181220 ROM, which, however, is better than 20181226, since with it I don't need a third-party app for my chuwi camera.
[Android General] nikaiako:
I updated magisk on my hybrid ROM to the v.20.1

To whom it may concern, here is a link to the 20180801 boot.img patched for Magisk v.20.1
[Android General] amg314:
To restore backups of system apps using Magisk 20.1 Titanium Backup Pro v8.4.0.1 is needed.

(I couldn't do it in my old TB v.8.3.1.2)
[Android General] NikosD:
I usually download the zip file only and flash it using TWRP (due to the encrypted partition, I copy the zip file to a USB stick and I use an OTG cable)

But the image is useful after a clean ROM installation, so thanks!
[Android General] nikaiako:
Yes, Nikos, me too. Now with Infect_Ed's twrp installed I simply copy a new magisk version zip file to the external SD card and flash it from there, the encrypted partition doesn't bother me, since Magisk has systemless nature, similar to the twrp exclusive patch.
[Android General] NikosD:
Exactly.

I only mentioned OTG cable, because if you download the zip file in your internal storage, TWRP doesn't see it due to the encryption.
[Android General] riceboyler:
FWIW, I flashed Christos's TWRP and have had no problem with the touch interface. I'd highly recommend it over Infect_ed's.
[Android General] NikosD:
Are you sure that it works with the original black button Hi9 Pro ?

I bought mine on August 2018, the month that Hi9 Pro was released.

Also, what TWRP version is Christos's based on ?

Infect_Ed's is 3.2.3
[Android General] riceboyler:
Honestly, I don't know about the Black button Hi9 Pro, I have a red button. Christos's TWRP is based on 3.2.3 as well. It'd be sweet if he could work the same magic with 3.3.1. I really need to sit down at some point and learn how to build all this crap... ;)
[Android General] dsahai:
Would you have the link to the recovery file?
[Android General] Infect_Ed:
FWIW, that TWRP is very outdated lol. Feel free to build it yourself. I still have the device but LCD died one day for no reason. And Chuwi refused to pay for it fully. So I had to stop development.

[Android General] NikosD:
Hello everyone.

Well...

I decided - mainly for security reasons - to flash the latest FW (05/01/2019) with bootloader locked, stock recovery and non-root.

I was ready to flash the first stock FW of 01/08 but i decided to give a chance to the newest FW.

It seems that for the first red button Chuwi Hi9 Pro, like mine, we can officially install only 01/08 and 15/11 FWs.

And I think the same goes for black button Hi9 Pro.

Only the new red button Hi9 Pro can officially flash 26/12 and 05/01 FWs.

It was good that [MENTION=9429197]nikaiako[/MENTION] IIRC was the first to report the "hack" of keeping the first boot.img and vendor.img of 01/08 FW, in order to flash the newest FWs to older devices.

I decided to try 05/01 in order to find out if it can reach 8 hours SOT like 01/08 or goes up to 6 hours like 26/12 - at least for me.

I read here that 05/01 FW could occasionally cause sudden reboots.

I had only one, during the first three days of using it.

The battery charging issue reappeared, as charging slows down after a percentage and ends up to 98% while charging <400 mAh (during normal charging goes at ~2200 mAh)

Regarding root, I couldn't make AdAway work but i tried a few others like AdGuard, Adclear but i decided to install DNS66 eventually.

I'm only missing Reboot managers that don't work without root, but i can live with that.

Anyway...

So far so good with 05/01 FW on my "ancient" August 2018 Red Button Hi9 Pro tablet.

Hi guys, someone was selling this tablet new for really cheap from china on ebay for $19 so I figured why not. should be here in a couple weeks. any recommendations on what I should do first? this tablet is supposed to get android 9 right? is there anything that can be done to make it faster?
