All Chuwi Hi9 Pro tablets, come with a cheap and usually badly placed screen/glass protector.

Remove it and touch the glass directly with your finger.

If this doesn't resolve your issue, it could be a recently introduced hardware flaw because no other old user of this tablet had similar problems.

I got mine on September 14th with no problem at all using touch screen with both older and newer stock ROM (OTA update)

Use your warranty in that case.
[Android General] Rhynko:
Ty, I see in the web of Chuwi a Stock rom for Black Power Button and Red button, i have the red, maybe need a special rom ? or is a same?
[Android General] s177oke77:
I have the Hi9 Pro with the red power button. I tried to use factory firmware listed on the chuwi forum. The red Firmware doesn't boot. The one I downloaded for another link here with Picasso in the filename works but I end up with the touch problem. The ota also works but same touch problem. I think the red power button requires a different version. If some one has a back up if there's that had a red button, can you please post?!
[Android General] nikaiako:
Chuwi also published a link to the HI9 pro "black power button" firmware, and this one is the 20181115 ota. http://www.mediafire.com/file/l5c3c7uocmn02hi/CHUWI_Hi9Pro_3+32_20181115_ota.zip

Update:

It seems there is a user report that the firmware is wrong, it refers to a bigger screen Chuwi tablet like Hi9 Air or Hi9 Plus.

Haven't tried yet and can't confirm or reject.
[Android General] Rhynko:
Maybe someone help us whit our backup of Red button, i really apreciated
[Android General] nikaiako:
It seems to me that "the black power button" ota firmware is exactly what we need for our "red button" device.
[Android General] Vihru:
i have red button and used normal firmwares :D
[Android General] nikaiako:
Which ones? Provide a link, please :)

UPD: Do you mean by "normal" that you've used the "red button" firmware? That one for smth with 8.0 screen and 4/64 memory?
[Android General] Vihru:
i used that needrom firmware.. also dropbox firmware, link is down now.

i will upload it again.
[Android General] nikaiako:
Ah, i know. That dropbox firmware is identical to the chuwi's "black button" ota firmware. https://www.dropbox.com/s/bccu8gcer68yl8n/CHUWI_Hi9Pro_3+32_20181115.rar?dl=0
[Android General] NikosD:
I used the firmware from [MENTION=4658487]Vihru[/MENTION] dropbox link and everything works fine, besides battery charging meter.

I have the "Red power" button version.
[Android General] nikaiako:
I have the "red power button" hi9 pro device too. I compared the "black power button" firmware from the Chuwi official forum and the 20181115 ota I used on my device, and I found that those are the same.

However, I migrated back to my memory dump made from the previous firmware. I like it more.

By the way, the battery calibration issue somehow dissipated. The repairing process took three days, little by little, and now it works quite fine as before.

I think that the latest firmware better fits for experiments with GSI roms of the treble project, but I prefer the 20180801 one for now.
[Android General] NikosD:
Interesting.

Could you describe the process step by step ?
[Android General] nikaiako:
First, I formatted the whole flash except Bootloader, then I flashed my memory dump (20180801 + apps + userdata), which I made in the beginning of December.

In the first cycle of discharging, the battery charge figure fell from 19% to 1% in three minutes as before, but I was able to use videoplayer for 15 minutes while on 1% of charge.

After that I calibrated the battery at zero per cent, and the charging process went smoothly to 100% without any issues.

I made the calibration once again, and during the following discharging cycle the abrupt fall began at 11%. Here, while being at 1% I was able to watch video for 45 minutes this time.

During the third discharging cycle the fall began at 4%. Et cetera.
[Android General] mathewcall:
I didn't even think to try taking the screen protector off but it worked fine the first few days with the screen protector on. It wasn't too poorly placed either. Not until I installed TWRP that it screwed up and never looked back even after re-locking, removing TWRP, and flashing stock ROM. Check it out LOL: https://youtu.be/y572KMwXvFA. Next one I get I just won't install TWRP.
[Android General] s177oke77:
I have the exact same problem, with the exact same steps that caused it. I flash twrp and ended up with the touch calibration issue. I did do a WWR (i am new to mediatek backups and flash process) backup before doing all that but my restore didn't make a difference. I have the exact same touch problem, the axis is not correct and is sometimes doubled depending on where i touch the screen.
[Android General] Rhynko:
I have exactly the same problem and did the same to install the twrp.
[Android General] NikosD:
The video is amazing, but I can't see how a custom recovery could cause that.

Maybe a slightly different Hi9 Pro device needs a slightly different TWRP.

Still, how these two (TWRP, touch screen) are connected ?
[Android General] mathewcall:
Glad to know I'm not alone! I'm stumped too. I think you are right about the slightly different Hi9 Pro device -- may have to do with the red button units vs. the black button units I'm just now reading about a few pages ago. It doesn't answer the question of how the TWRP and touch screen are connected though. The strangest part is restoring it or putting stock ROM back on doesn't resolve it. At the point the touch gets screwed up, the tablet becomes useless without an OTG mouse plugged in. (The good thing is the mouse works immediately upon plugging it in no matter what screen you're on, even within TWRP.) From my endless searching online it probably is possible to edit the code and get it back to normal but you have to know exactly how the axes are off to bring them back to normal. And from the looks of it, it's not a simple fix. Seems to be altered in several ways. Way beyond my expertise. Anyways I think the solution is we need two different versions of TWRP for this device.
[Android General] NikosD:
Have you tried both TWRPs posted in this thread or even some other TWRP built for Hi9 Pro from external source ?
[Android General] s177oke77:
Can someone here build a TWRP for the red devices? Building a recovery from source is beyond my capabilities. Do you need a Linux machine to build?
[Android General] NikosD:
The OP has built a TWRP from Hi9 Air TWRP and [MENTION=7987739]Infect_Ed[/MENTION] has built a TWRP from scratch.

But I can't see how they could build a TWRP without the device, the specific maybe a little different device.
[Android General] NikosD:
It is truly very well known that when you change ROM you have to calibrate your battery in order to get accurate values.

But I'm 100% sure that nobody in this world can calibrate 20181115 OTA update firmware.

The ROM has simply a bug and I dare anyone to prove me wrong.

I just have to stop trying calibrate the battery using this firmware of Chuwi.
[Android General] nikaiako:
Did you try the latest version of the Chuwi hi9 pro 20181115 "red power button android" that they released four days ago? I just installed it. https://forum.chuwi.com/forum.php?mod=viewthread&tid=9501&extra=page=1&filter=typeid&typeid=92
[Android General] NikosD:
Chuwi is surely in total confusion right now with so many similar X20/X23/X27 tablets.

The post is there for more than 10 days and it has already been installed by a user of this forum who has posted at Chuwi's forum just below the original link.

I have already posted here the initial links and the update of another user saying that it was a wrong link, because Chuwi actually gave a firmware of another tablet - probably Hi9 Plus - in Hi9 Pro section !

I don't know if they changed a few days back the link and the latest firmware is suitable for our device.

Please post any differences that you may find, especially on the charging issue.
[Android General] nikaiako:
They changed the link under the "red button" section 4 days ago, and I downloaded what was there. The size of the firmware is exactly the same as of the "black button" or whatever.

I installed it via sp flash tool, "download only" mode, simply not having checked the preloader, cache and userdata boxes to avoid losing my settings. I also used my patched boot instead of the original.

It works fine for twenty minutes already. I will start charging the battery from zero. Wait for the result.
[Android General] nikaiako:
The charging issue is still there, alas, nothing changed.
[Android General] nikaiako:
These are screenshots of the 20181115 firmware for the "hi9pro with red button"

Hello i have hi9pro but with Xelio x27 instead of x20/23. Very often i have inaspectate app crash and firmware reboot.. Firmware is 20180801...help please
[Android General] NikosD:
Most of the times this is due to an app installation.

And because you can't be sure which app exactly caused this behavior, you have to start uninstalling apps from last to first installed.
[Android General] Etnoso:
Lol, just few minutes ago appeared me an ota update, i downloaded it, but the installation fails.

---------- Post added at 10:04 PM ---------- Previous post was at 10:02 PM ----------

There is. They sent out a broken update. Even posted the wrong firmware in their forums. Apparently there's a red button and black button version. Didn't know there was 2. I have a red button.
[Android General] Infect_Ed:
We have a factory programmer and factory firmware. It's never totally f*******. If you can't find it on the chuwi forums, I think I have it. I'll see if I can zip it up and upload it. It's the original zip, not these newer even more messed up builds. Let me know if you need it.

---------- Post added at 03:44 PM ---------- Previous post was at 03:37 PM ----------

This whole thing with them and the messed up firmware is ridiculous. I'm going to take a look at the difference between the two zips. If I need to I'll add some patches if possible to my tree and build a new recovery image. I can't test the black button device if it is needed. So I need to find a black button tester as well.
[Android General] Vihru:
i dont also get it about messed up firmware.

i have tried about all firmwares and everything working fine.
[Android General] Christos2714:
Yes please please please upload the proper built and make a recovery for the red button as the rom my tablet has is pretty much for THE BIN!

[Android General] Christos2714:
Either the firmware nor the TWRP does not work with my red button Hi9 Pro.

Could it be that the one I have has a diferent screen? I wonder.

I have backups of the ROM. Would those be of any help for compiling a TWRP?
[Android General] nikaiako:
One guy from the Russian 4PDA forum just bought a brand new Chuwi Hi9 pro with a red-coloured button, and it turned out that the device had different firmware out of the box, compare to ours: Build number O00 623 release-keys OGS 20181226, Kernel version 3.18.60 zengqb@jty #3 Wed Dec 26

The guy was unable to unlock bootloader on the device, and he decided to "update" it with the firmware that he found under the "Chuwi Hi9 pro with the red button" section of the official Chuwi forum, i.e. Build number O00 623 release-keys 20181115, Kernel version 3.18.60 zengqb@jty #6 Thu Nov 15.

And he immediately got the touchscreen issue that had been already discussed in this forum. I have to mention here that he didn't install TWRP at all before he got his touchscreen out of sync.

An attempt to fix the issue by flashing the 20180801 firmware didn't help to solve the problem.

So we need someone with the new version of the device to make the firmware dump.
[Android General] NikosD:
By reading various posts here and Chuwi forums, it's very clear for me that the original Red Button Hi9 Pro that we have are different than the new Red Button tablets.

The right firmware for us it's probably the Black Button version (!)

It's totally FUBAR.
[Android General] Vihru:
i have red button but used that 1115 firmwaremm without no issues
[Android General] nikaiako:
Me too. My device with the red button was provided with the 20180801 firmware out of the box.

However, those who bought Chuwi Hi9 pro with a red button, say, in March 2019, appeared to have smth like 20181226 stock firmware. I never heard of it before I saw the screenshot today.

So, some of them due to unknown reasons decide to "update" to 20181115 which they find on the official Chuwi forum, and therefore catch the touchscreen illness.

Guys, here is my dump from original rom chuwi Hi 9 Pro I purchased a couple of months ago.

New rom incompatible with the older one. Even those stupid people from CHUWI forum are not giving the ROM for this tablet.

I emailed customer support, gave her the serial number of my device. She gave me the same link from the CHUWI forum.

When I told her it does not work she refused to answer to my further emails. THIS IS A DISGRACE!

hOPEFULLY THE FIRST THING i DID WHEN UNBOXED THE TABLET WAS TO DO FULL rom BACKUPS WITH SPFLASH AND wWr mtk. Now I can sleep in peace.

Flash it back, restore your IMEI's with a program of your choise, install Magisk, patch the boot.img and replace it with spflash and you are rooted.

Guys can someone make a TWRP that works with this ROM?

That would be really nice. The most important thing with TWRP is to make directly backups from your phone.
[Android General] NikosD:
[MENTION=7987739]Infect_Ed[/MENTION]

New TWRP v.3.3.0 is out.

I don't know if it's possible for you to port it to Hi9 Pro.

Thanks!
[Android General] Infect_Ed:
Anything is possible. But I need need to find the difference between the three. If there even is 3 of them...
[Android General] NikosD:
If you mean the three (?) versions of Hi9 Pro then I suggest to just start from our version and later you can move on to the others.
[Android General] Infect_Ed:
Show me which firmware is ours and I'll make it happen. I'm still on old firmware. Also, classes are coming to an end. So I'll pick back up on development in a few weeks. Being 36 and working 50 hours a week, with 3 kids and going to school 3 nights a week is not easy lol.
[Android General] NikosD:
I wouldn't count on any new firmware.

My new firmware is working but it has that new annoying bug, or we should call it "feature", allowing to charge the battery up to 80% Max.

So, forget new firmware and stick to the original 08012018 that came with our devices.
[Android General] Infect_Ed:
If that's the case, then why build a new TWRP? As the other one works just fine.
[Android General] NikosD:
New features ?

Bugs fixed ?

Progress ?

I don't know...
[Android General] Infect_Ed:
I'm kinda worried to do so. People have been bricking their device because of bad firmware. [MENTION=5034664]NikosD[/MENTION] pm me. Once I get it done, I'll have you test along with myself obviously. I don't want to release anything and potentially cause problems for others devices. Plus... I want to try and make one TWRP for all the supposed variants. If fstab varies between them, then I'll make different builds. But I doubt they do.
[Android General] Evans_jd:
Hi

Looking for help!

I flashed TWRP on my 2 week old Hi9 Pro (has red power button)

When I booted into recovery, the touch screen wasnt working right.

So, I flashed back to stock using the firmware on Chuwi's download page.

Now I have the calibration issue for the screen, as per the video that was posted in earlier (https://www.youtube.com/watch?v=y572KMwXvFA&feature=youtu.be)

I've tried different releases of the ROM that I can get hold of, but all have the same.

Any ideas?
[Android General] Infect_Ed:
What recovery did you use? There is a latency bug that I never fixed. When you first boot up, touch is unresponsive for a few seconds. It goes back to normal after a few.
[Android General] Evans_jd:
I used the TWRP from the first post.

I did boot into TWRP and left it for a good 30 seconds but still no response.

The issue with the screen calibration, you think is somehow related to this?
[Android General] Infect_Ed:
Use this one

thanks, will try shortly

---------- Post added at 01:59 PM ---------- Previous post was at 01:50 PM ----------

OK, have TWRP flashed.

So, the issue wasnt that the screen was unresponsive - it is the issue that the calibration is off.

The issue appeared after flashing TWRP and despite going back to various stock versions the issue persists.

Anything idea?

---------- Post added at 02:05 PM ---------- Previous post was at 01:59 PM ----------

Does seem to be an issue with other devices

[Android General] KilgoreT:
I have exactly the same problem as Evans. My touch screen mapping is broken after rooting and flashing stock. I have tablet for two weeks.

That's what I did: I rooted Hi9 Pro with TWRP from InfectEd. Touch on TWRP didn't work but I used mouse connected through OTG. System got wiped out by unlocking the OEM via fastboot. I downloaded newest stock firmware from Chuwi site and flashed it (Sp Flash Tool). Tablet booted into the system and everything was fine. I booted to TWRP but TWRP couldn't see magisk zip so I transferred it to outside sd card, inserted sd into tablet and used TWRP (with mouse) to install zip. TABLET WAS SUCCESSFULLY ROOTED.

But I was stupid. I decided to flash stock ROM again to get clean install (I played with KingRoot after first TWRP problems). What I did differently this time was to flash all including BOOT.img. Flashing stock first time flash I didn't "ticked" boot.img - now I did. After that I have dysfunctional touch screen.

I suspect the boot.img in the firmware from Chuwi website has to be bad. If anybody could upload boot.img from working tablet Hi9 Pro I would be very grateful. I tried two stock versions available online and I couldn't make touch screen working again.
[Android General] Evans_jd:
Glad its not just me!

Right now, I will be happy back with stock, no root and a working screen
[Android General] KilgoreT:
I thought that you also had problem with your touch screen. Did you manage to flash stock ROM and get screen working or you had it dysfunctional only in TWRP?
[Android General] Evans_jd:
Reading your post..

You saying after installing TWRP, then flashing System you had a working tablet - screen calibration also?

You suspect Boot is corrupt in the stock roms.
[Android General] KilgoreT:
Yes but only the first time when I didn't include boot.img while flashing. Tablet was fine with root verified.

When I flashed stock rom for the second time - boot.img included - display went nuts. (And I didn't make backup of original boot.img.)
[Android General] Evans_jd:
Not working in system.

Tried going back to stock by flashing the rom from Chuwi download page.

---------- Post added at 03:13 PM ---------- Previous post was at 03:08 PM ----------

Can someone upload Boot.img?

My tablet is 2 weeks old, red power button
[Android General] KilgoreT:
Update. I wiped all and flashed stock ROM with wrong boot.img (from Hi9) - on purpuse. My Hi9 Pro behaves exactly the same with wrong boot.img. Everything works but touch screen.

That means that boot.img from Chuwi website is no good if swapping it with some other gives the same results. If anyone could upload his/her boot.img from working tablet would be great.
[Android General] NikosD:
The new "red button" is not the same like our old "red button".

[MENTION=7987739]Infect_Ed[/MENTION]

Hi9 Pro is being used by me as my one and only device as phone and tablet together.

I can't risk it going something wrong.

If you find me a way to test your TWRP versions without risk and without breaking the installed apps and the unencrypted storage, I have no problem testing your TWRP.
[Android General] KilgoreT:
That's true. I've just found note on Bangood listing:

"The CPU have been changed to MT6797D X23 from October 26"

I was stupid not to make a backup of the firmware. Just checked they had it and went on with rooting. Big mistake.
[Android General] KilgoreT:
Thank you Ed I rooted new Hi9 Pro (red button) tablet with your TWRP with the help of outside mouse and outside micro SD. However it took me many hours because I hadn't made backup. Actually it's better to flash TWRP without unlocking OEM.

Please issue a warning in the first page of the thread like I did in Chuwi website. The new Chuwi has different CPU than the one in the beginning. Chuwi website does not provide proper firmware for this model. Neither your current TWRP works like it should - no touch screen, no storage recognition (0B). Whoever got trapped like me can check the solution in this thread above (Thank you Christos for making your backup available).
[Android General] pfroo40:
I am a little stuck, I also have the newer red button, I was able to unlock the bootloader and flash twrp but also had the touch screen issues. So, I used a usbc hub with mouse and a flash drive, I used wipe to format the userdata partition and then flashed the encryption remover zip and Magisk. I rebooted, it took a while to boot, I went through setup and tested root, which failed. So I checked encryption status and my drive is encrypted again.

Any tips on what I did wrong? Should I have rebooted recovery after wiping userdata?

Thanks!
