i downloaded from needrom newer one and flashed it.. i think battery is good for now.. but performance need optimizeing..
[Android General] NikosD:
Is it official ?

Is there a change log ?

You could post a link if you wish.
[Android General] Vihru:
i try tomorrow upload whole firmware to mega or somewhere.

i dont have any changelog and i think its official.. but not sure..
[Android General] jmacie:
I tried to root my Hi9+ today. I'm soft bricked. I enabled usb debugging and oem unlock in developers options. I rebooted into fastboot mode and did "fastboot oem unlock" Upon reboot I got the Chuwi logon screen with the small "orange screen" comment saying the bootloader was unlocked. I booted to Android to re-do usb debugging and proceeded to fastboot again to bootloader to flash custom recovery. After flashing new recovery I sent a command to reboot into new recovery " fastboot boot recovery.img" and it wrote a boot.img and booted to the Chuwi logo screen and after a few seconds it just shuts off. When I try to power on it just shows thw Chuwi logon screen for 6 seconds then powers off. Any suggestions? Thanks John M
[Android General] zelipukin:
"fastboot boot recovery.img"

is not for rebooting into your current recovery, it's for temporary booting into recovery mode using .img from PC.

I never used this command.

Can you boot into twrp with buttons combination ?

If not, try to reflash recovery.img

if not booting into system

try to flash boot.img.
[Android General] Vihru:
you maybe need flash whole firmware with sp tools?
[Android General] jmacie:
Thank you, I can't boot anywhere. I tried to get into recovery with holding volume up and pressing the power button, but I only get the Chuwi logo screen for 6 seconds then it powers off. Tried many times to get into recovery, really appreciate your help. I don't know what to do, let me know if you have any other ideas

---------- Post added at 04:46 PM ---------- Previous post was at 04:44 PM ----------

I will have to read up on flashing with sp tools, I appreciate you giving me help. If you have any other ideas I'm willing to try, I just got this tablet from Chima today and I couldn't restrain myself and so now I'm stuck. Thanks again!
[Android General] Vihru:
let see tomorrow again, i will help you more if you need.. now i need to go to sleep..
[Android General] jmacie:
Thank you, I appreciate it, I am looking for sp tools and tutorial, Thanks again

Hooray, sp tools kind of worked. I did get an older rom, and the display flickers, and google play is wrecking havoc on me because it's not installed right in this old rom, but Thanks so much at least I'm not bricked and I'll hopefully get a newer rom.

P.S. Thanks and sorry to the OP, I couldn't find any Chuwi Hi9+ threads and I was panicking! I appreciate all the help, JohnM

May have to ask for your help to try and explain how someone can extract their ROM for me. I don't know how, and have asked on the CHUWI forum for help, but am not expecting much help. So if there is an easy way you can recommend for me to explain to another Hi9+ owner to extract and share their ROM, I'd appreciate it, Thanks Johnm
[Android General] Infect_Ed:
Yeah you're going to have to use spflash and restore that way. I was there at one point.

Here's my latest TWRP build from source if anyone would like to try.

https://drive.google.com/open?id=1EvPdYfMgdVVLnmpxPNWIGLyEc4Wd6wWV
[Android General] zelipukin:
Jmacie

You mentioned hi9+, is that correct that you've flashed Pro's crap to + ?

Infect_Ed

I'll put a link in op.

Any luck with mounting encrypted userdata ?
[Android General] Infect_Ed:
Seems to be working fine.
[Android General] zelipukin:
Infect_Ed

Ok, thank you.

I've changed the op according to new data.

Just one question to make sure.

If you click "Encryption & credentials" what's on the next screen ?

Asking because, though, my tablet is decrypted I have the same greyed message "Device encrypted".

This is scrshot of next screen:
[Android General] NikosD:
[MENTION=7987739]Infect_Ed[/MENTION]

As zelipukin has already said, the first screen says nothing for the encryption of the tablet.

Go to second screen to find out what is really going on.

[MENTION=9350973]All[/MENTION]

Those of us who have Magisk v17.1 installed via patched boot.img, how do we upgrade to v18 ?

I tried the recommended mode via Direct Install and it didn't work.

I think we have to patch the boot.img file.

Thx
[Android General] Infect_Ed:
I believe all I have to do is hook it up to the charger to allow it to encrypt. I'll verify in a little bit. But here is some screenshots. I'm about to flash my lineage 15.1 build right now she see if it boots.
[Android General] Infect_Ed:
It probably won't boot, but it's a start.

---------- Post added at 09:26 PM ---------- Previous post was at 09:22 PM ----------

As for magisk, just do it in magisk manager
[Android General] NikosD:
The options I mentioned above of "Direct Install(recommended)" and "patch boot.img" are from there.

The recommended option from Magisk Manager doesn't work.
[Android General] zelipukin:
v18 and prev. upgrade didn't work for me via manager. had to flash it in twrp
[Android General] Infect_Ed:
What TWRP do you have installed? Mine or the original? The original is a port, so it may not be kosher in the fstab. I was able to do it with my TWRP installed.
[Android General] zelipukin:
Infect_Ed

So, its not encrypted.

We still need confirmation if your twrp works w. encr. userdata.

If you replaced fstab.mt6797 in vendor/etc youll not be able encrypt from "Settings". need to put orig. fstab and it will encrypt next boot.

good luck w. LOS!
[Android General] NikosD:
I still have the first one, but how is that relative ?

I didn't try to install Magisk via TWRP but using Magisk Manager.

Does Magisk Manager somehow need/use TWRP ?
[Android General] Infect_Ed:
It is the original fstab. Just made some modifications to it.

---------- Post added at 09:44 PM ---------- Previous post was at 09:42 PM ----------

No it doesn't need/use TWRP. But if the fstab is not correct, it can't patch the boot.img.

Los didn't boot. I need to take some logs, but I'm at work right now. Restoring a backup as we speak.

---------- Post added at 09:54 PM ---------- Previous post was at 09:44 PM ----------

I'm actually gonna try and flash one more time. Going to backup to the sdcard and then format the device. Then flash again
[Android General] Vihru:
what? is there LOS for this Chuwi Hi9 pro?
[Android General] Infect_Ed:
Nope. Not yet. I probably won't release the Lineage build. I'm not a part of the Lineage team. I'm a core member of InvictrixRom. I'm just using Lineage as a common base for bring up. I'll let you guys know when I get boot. I'll prob have Nikos and OP test once it boots. There will be a lot of bugs to work out.
[Android General] Vihru:
Thats still very nice to hear. i can also be tester if you need. would be nice maybe someday see lineageos in our hi9 pro. thanks for your work and keep going!
[Android General] Vihru:
so what easiest way now to root this tablet?

need unlocked bootloader first?
[Android General] NikosD:
I'm under the impression that using SPFlashTool without unlocking bootloader, you could patch boot.img of the OP and the new recovery.img and have both a Magisk rooted device and a TWRP custom recovery.

The original ROM and the SPFlashTool can probably do it.
[Android General] lewmur:
My reading of the OP is that the only thing you can do BEFORE unlocking the bootloader is use SPFlash to BACKUP. Then use adb fastboot to unlock before flashing the TWRP recovery image. I know that is what I did.
[Android General] NikosD:
I suggested the above process after reading the Hi9 Air thread and what the developer suggested there.

I think there is a way to root the device and flash TWRP using SPFlashTool without unlocking the bootloader.

The tool is powerful and interacts with the device before secure boot processing.
[Android General] lewmur:
You may be right, but until you can give step by step instructions, that someone else can successfully duplicate, I'll stick with what has been proven to work.
[Android General] Vihru:
same was with motorola, i was able to flash twrp via sp tools..
[Android General] Infect_Ed:
Noticed something strange while flashing my lineage build. When it begins to flash, it thinks it's a hi9plus. So I grepped my tree, and it's the boot image, which I pulled from the stock ROM. Seems that the hi9plus and hi9pro use the same boot image. So I can only speculate that the hi9air does as well. [MENTION=5034664]NikosD[/MENTION] [MENTION=1980576]zelipukin[/MENTION] do either of you have a telegram account? If you do, pm me your tag and I'll start a chat on there so we can kick around a few ideas on how to get this damn thing booting, so I can work on 9.0 pie.
[Android General] Vihru:
my tablet back cover says cwi532 and its hi9 pro.

when you google that cwi532, it founds chuwi hi9 plus...

also aida says that i have x27...
[Android General] jaymebadfan:
Hello.

I need some urgent help. My Hi9 Pro asks for the google account after the hard reset. Yeah, I forgot the bill. I have already seen several methods to remove this check from google account. Does anyone know of an effective method? :(
[Android General] Vihru:
you forgot your google account?
[Android General] lewmur:
The methods for removing the FRP lock are device dependent and this device is probably too new for a solution to be found. If you don't remember your Google account info, then you MUST have proof of ownership to get Google or Chuwi to unlock the device. The whole purpose of the lock is to prevent thieves from using the tablet. If it were easy to bypass it would be worthless.

The very first step with any new tablet should be to set it up with a FAMILIAR Google account that won't be forgotten. The second step would be to enable developer option and them make sure OEM is enable. That prevents the FRP lock from engaging.
[Android General] Infect_Ed:
You should be able to flash stock firmware with SP flash and be good to go.
[Android General] jmacie:
I have a Hi9+ and messed up the root, so I had to flash the only Chuwi ROM they have to get back working. It is not a complete ROM as it is not registered and the camera is inoperable. I got the tablet registered and some are working on fixing the camera.

What I wanted to know is did this happen to you and/or how did you deal with it. I tried to contact Chuwi, but they are as unresponsive as many tech companies I have products from i.e. Tanix and LG. The system wireless OTA doesn't update, so I'm even wondering if they'll EVER give us a functional ROM. Thanks for all your time and help in the past. Happy Holidays, Johnm

https://xdaforums.com/general/devic...tion/chuwi-hi9-plus-unlock-root-twrp-t3863722

Keep in mind, this is older software than what is actually shipped. You're gonna have to use sp flash to restore.
[Android General] NikosD:
Your TWRP is latest version of 3.2.3 instead of the OP which is ported by Hi9 Air and it's version 3.2.2.

I think it's the first time that I save the Time Zone and other preferences and TWRP keeps the settings after reboot!

Your TWRP could be perfect if it didn't have smaller font size than the ported one.

Is it possible to change the font size ?

Also, please consider the idea of registering officially your TWRP to TWRP unofficial builds in order to show up in their site as an officially unofficial build with a download link there.
[Android General] Infect_Ed:
I would rather focus my time on getting pie booting. But thank you for the compliment.
[Android General] NikosD:
[MENTION=7987739]Infect_Ed[/MENTION]

Maybe next time when you find time and you are in the mood, you could try to make font size a user setting in order to change it accordingly.

On December 7th, unfortunately I was stolen by a couple in a coffee shop.

They took me my bag with everything inside including my second device an old Samsung phone that I had it for backup of this tablet.

Since that phone used to be my second phone when I soft bricked my Hi9 Pro, I'm not in a mood right now to do experiments and loose my only phone - this tablet - as I don't have any other device or money to buy another phone.

Keep up the good work with GSI ROMs and Android Pie!
[Android General] Infect_Ed:
Wtf... That's messed up.
[Android General] zelipukin:
NikosD

font size

Unpack TWRP using one of the utilities (f.e. ImgExtractor) on your phone or pc

Go to /initrd/twres/ui.xml

(if use PC, don't use Notepad or Word to edit file, use Notepad++ or similar)

Adjust font(s) size.

Repack and flash.

Not sure about size and what font goes where ? - just experiment several times.
[Android General] Vihru:
any success on it?
[Android General] Infect_Ed:
Not yet. Won't even reach init. I've done prob 30 builds over the last 5 days... This device is an asshole. I've also tried to make PitchBlackRecovery for it, but our recovery partition is too small for it. I have tried to compress the ram-disk but it doesn't boot if I do that. I could if I had kernel source. But with prebuilt kernel its no go.
[Android General] Infect_Ed:
Getting closer....
[Android General] Vihru:
what? :p
[Android General] Infect_Ed:
Labs sucks. It never attaches the photos or screenshots.

[Android General] Vihru:
awesome! is it early to ask that how its working?

Chuwi Hi9 Pro stock rom is so lagging for me...
[Android General] Infect_Ed:
It's not lol. I can only get to splash screen right now.
[Android General] Vihru:
that still better than nothing! Chuwi promised android 9 in this year.. hope it comes and gives better performance.
[Android General] Infect_Ed:
I highly doubt they will release it for hi9-series. Maybe for a new product.
[Android General] Vihru:
look this
[Android General] Infect_Ed:
I'll believe it when I see it.
[Android General] lewmur:
That means we MIGHT get it for NEXT Christmas.:D

All x20 tablets will get Android 9.0 on June 2019:
[Android General] Infect_Ed:

[Android General] Vihru:
ouh. so long time.
[Android General] lewmur:
Not really. My Samsung tablet is just now getting Oreo.:)
[Android General] kelu:
looking forward for an update, I have the Chuwi Hi9 Pro x23 and it is a bit sluggish sometimes, not sure if Android 9 will make it better or worse ... but it is very good for its price .. so no complains :)
[Android General] Vihru:
its lagging yeah.. dont know why..
[Android General] NikosD:
X20 Hi9 Pro isn't lagging, at all.

It's speedy enough for everything. (Faster than Snapdragon 626 but slower than 660)

Now, in theory X23 should be a little faster than X20.

If X23 lags, then it could be a thermal problem - not easy to get it fixed by a software/ROM update.
[Android General] Infect_Ed:
I have the x20 and it's definitely sluggish.
[Android General] Vihru:
it must be software because some apps works fine..
[Android General] NikosD:
Another clue that it's probably HW.
[Android General] Infect_Ed:
Nah it's the GPU in our device. Subpar at best.
[Android General] Vihru:
subpar? what you mean?
[Android General] Infect_Ed:
I mean it's not equal to it's adreno rival. I've been an avid user of Qualcomm devices. This being my first mediatek device, I am not impressed at the quality of the GPU. Maybe it is stock firmware that's holding it back. I won't know until I get this tablet booting. Which btw, I am very close to doing so.
[Android General] Vihru:
i think its not that bad.. its only about firmware/software optimization.. im sure of that. because some apps/games working good.. like homescreen lags and apps changing.. i think it usable tablet when we get better software.
[Android General] NikosD:
This could be identified as a slow memory problem and/or less than adequate quantity of memory (3GB)

But that could be an issue for X20 too.

Fortunately, 3GB is good enough for Pie.
[Android General] Infect_Ed:
3 is eh... 4 is just fine. All these devices with 8 & 10g of RAM is overkill. But 3 is definitely ok for everyday use as a tablet. To be marketed as a "Gaming Tablet" is not ok tho. This thing gets hot just doing light weight work.
[Android General] lewmur:
Is it realistic to expect "gaming performance" from a $140 tablet?

---------- Post added at 09:42 AM ---------- Previous post was at 08:59 AM ----------

Anyone know how to turn on Safe Mode on this device? Holding vol down when logo screen appears, doesn't seem to work.
[Android General] Infect_Ed:
If it's marketed as such, yes lol. I didn't pay for mine either... So my opinion is not biased. I received mine directly from Chuwi, for the sole purpose of review and development.
[Android General] lewmur:
Aw come on! "Marketed as such"? By the Chinese? You still believe in Santa Claus?:D
[Android General] Infect_Ed:
**Senses heavy sarcasm**

---------- Post added at 05:49 PM ---------- Previous post was at 05:46 PM ----------

I have a feeling this thing is going to run much better when I get boot. I'm currently stuck ATM. Just boot animation. And last_kmsg is vague... It's not detecting the hardware. I'll figure it out. #soon
[Android General] lewmur:
I'm all in favor of what you are attempting. If you CAN get the tablet to perform as a gaming device, I'll be one of the first to thank you. I just get tired of people whining when a $140 device doesn't perform like a $1000 one. I have a Surface Pro 3 that cost a lot when new, but it never was much good as a gaming tablet.
[Android General] kelu:
I'm willing to also test it once you get it running, thanks Infect_Ed :)
[Android General] Vihru:
its not gaming tablet but also it should be better with that hardware. i had chuwi tablets before and also xiaomi tablets with lower performance. thats why im sure that this tablet just need software optimazing.
[Android General] banch:
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:

I copied this reply from Chuwi Hi9 AIR thread because I fought 3months with constant crashing and now for the first time device has been running for 5hrs without a hitch!

[Android General] zelipukin:
I don't play games, except Doom (the original one, so this is not about the grafic) but in comparision to my sd650 MiMax, Chuwi has a noticeable touch input lag that makes me feel uncomfortable to play on this device
[Android General] Vihru:
how it goes? thats very nice news! i mean performance..

this is chuwi hi9 pro thread? are you speaking now same device..
[Android General] 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
[Android General] NikosD:
Using TWRP it worked even without uninstalling previous Magisk version and using the same Magisk Manager v6.1.0

I tried installing VIPER4Android both FX and XHiFi using Magisk modules installer and it couldn't install the driver for both modules.

How could I install VIPER4Android or any other (better) audio enhancer ?

Thanks.
[Android General] zelipukin:
NicosD

I used advice given by Nikaiako from russian 4pda

download (Magisk) Dolby Digital Plus

download (Magisk) Audio Modification Library

I used TWRP to install these 2 modules

bc some modules installed via Magisk just don't work for me.

(some modules don't work for me even installed via TWRP)

Install dolby first then library, dont need to reboot btwn.

Install (gplay) SELinuxModeChanger and set it to Permessive

After reboot SELinuxModeChanger throws an error but keeps Permessive mode.

You can make a quick check if module works for you by switching "volume leveler" to On - you'll hear how volume increases.
[Android General] NikosD:
[MENTION=1980576]zelipukin[/MENTION]

I mainly want to improve the quality of sound during video playback of various sources (YouTube, Facebook, browsers) and during phone calls.

Does the above software suggested by you worth the effort ?

Because I think Dolby Digital Plus is just a rare audio codec and I don't know how useful could that be.
[Android General] zelipukin:
IMHO, any sound coming from any phone (speakers or headphones) is crap in therms of music listening. unless you are using ext. usb dac.

dolby might help in some situations to make sound more acceptable. it has presets for voice, movie, game and you can try to use manual equalizer as well.

it takes a few minutes to install and try.

though you can disable/uninstall modules anytime but I prefer to do a backup before playing with things like this. (I had a bad experience in past w. audio modules not uninstalled correctly)
[Android General] Vihru:
hope we get some custom rom for hi9 pro.. :)
[Android General] NikosD:

[Android General] geronracing:
Hi ya'll. Thanks for the awesome discussions here.

Quick somewhat off topic question. This Hi9pro will not run android auto. When I open android auto and connect it to the vehicle it makes the tablet go into a semi-reboot loop. IE the Chuwei boot screen shows up, it turns on to the lock screen and then keeps repeating until i disconnect the USB from the vehicle.

Any insight into what could cause this? I tried it before rooting the tablet, and also tried rooting and giving android auto super user and it still does it..... I bought this tablet to use as an in-vehicle data device, with casting the screen to android auto, so the tablet is useless without it.

Appreciate the insights! Thanks
