Days or weeks??? Thats the status from Banggoods now!

Do I want to proceed with the order? Seems thats why I payed them 4/15/2018. So glad one has shown up in the real world though as it is reason for hope! It could be days/weeks before shipment they say today. I have since tried contacting Banggood through Paypal instead of the Banggood contact us button and may indeed cancel as they can't reliably say when it may ship. I may wait til this becomes more available through AliExpress and reorder. It would seem they could tell when an order from 4/15/2018 could ship I mean really. Quantity in, quantity out....Not having a Banggood time for sure.:(:(:(

Now that you’ve fixed the brightness bug, any comments on the brightness of the screen?

A few of the banggood reviews and the techtablets review are saying the screen isn’t very bright.

It would be a shame as I’m upgrading from a Hibook Pro and that has a lovely screen.

Had my order in at banggood since 23 April with no movement. Have put another one in at gearbest who say they’ll ship in three days.

Dear Loyal Customers,

Big congratulations to you if you already received Hi9 Air enjoying the new features of Android Oreo ahead of others, also to you who had the tracking code expecting your package anytime soon.

If your order is scheduled to ship out next week, our retail partner Banggood will offer a $10 coupon for a leather case (valued at $14.99) via newsletter around mid May as a reimbursement for delay.

Thanks for being patient and supportive as always.

Hey Alberto, one quick question. Do you think we should be flashing stock ROM for each new build? Only because I'm noticing that the bootloader remains unlocked when reverting back to stock ROM.. Seems like a waste of time if its only to unlock bootloader. But I'm not the expert here.
[Device Reviews and Information] Serg.dv77:
Please give me normal twrp without unlocked bootloader
[Device Reviews and Information] RobBrownNZ:
That's interesting, my bootloader always gets re-locked when I revert to stock. How are you doing it? SP Flash Tool?

---------- Post added at 08:58 PM ---------- Previous post was at 08:37 PM ----------

This hasn't changed much for me, although I do have some observations:

- The Lineage setup still glitched, but I noticed that if I leave it in the glitched state (with corrupted display etc) for 10-15 minutes it does move on to the next screen. It will glitch again but then leaving it a few minutes will give a 'setup app is hung' error, you can choose to wait for it and it will exit successfully. I didn't notice this with earlier builds but it's possible that that's how it's always been.

- I installed the Hovatek TWRP just for giggles, it still fails to install OpenGApps but it gives a different error message: "This GApps pkg is for Android 8.1.x ONLY. Please download the correct version for your ROM: 5.1.1 (SDK22)". I wonder where it gets the idea that the ROM is version 5.1.1?
[Device Reviews and Information] Opmovers:
sp flashtool yes, but i replaced the recovery img in the stock rom folder with the recovery img from albertos v1.0

HOWEVER! i was very drunk last night and may have imagined the bootloader being unlocked. but TWRP recovery seems to work just fine flashing it this way.

---------- Post added at 10:07 AM ---------- Previous post was at 10:01 AM ----------

I am also keeping an eye out. I own/operate a piano moving company so i need something volcano proof. but ill settle for bullet proof. I am hoping to find something that looks professional/executive yet has an exoskeleton for the tablet that will protect it from a (minimum) 6 foot drop. Tempered glass Screen guard on the radar too yet should be much easier to find.

Cheers!
[Device Reviews and Information] Alberto96:
There are multiple guides on Google on how to obtain logs via adb ;)

Not required if you upgrade from a previous build. Also, i don't know how you install the Stock ROM but in my case the BL gets relocked everytime i flash it via SP Flash Tool.
[Device Reviews and Information] Alberto96:
- WTF...i can't reproduce glitches anymore without animations, really weird issue.

- Hovatek's build was 100% messed up, avoid it.

I think he is searching for a TPU or Rugged one, something not available for this tablet unfortunately. I got the original CHUWI one from a seller (AliEx) that was also providing a glass screen protector with a small extra, perfect fit, but quite useless in case of drops since it is rigid.
[Device Reviews and Information] Emoclaw:
The stock gapps package works well on the latest build. With this package the "WebView implementation" is set to Chrome in Developer options.

This wasn't the case with the other gapps packages. Even when I installed android system webview & chrome separately, I couldn't change the webview implementation because the list was empty.

Clock and Maps FC so I deleted them. Everything else seems to work fine.

GearLabs ROM (v3 20180917)

GearLabs ROM​

This is just a modified Stock ROM containing some improvements and fixes in order to provide the best user experience possible, until GSIs get a proper documentation to replace completely, and properly, the stock software. Basically, this is how CHUWI should have released the software by default.

Download Folder:: https://www.androidfilehost.com/?w=files&flid=279461

Please make sure to have the latest August 2018 Stock ROM installed on your device before proceeding.

Install it via fastboot (fastboot flash boot boot.img & fastboot flash system system.img), remember to unlock the BL first if you haven't already. The installation process may take up to 20 minutes depending on your PC and USB connection stability, then reboot the device (fastboot reboot).

You can install it via SP Flash Tool too if you use the original scatter file from the Stock ROM if you prefer to keep your bootloader locked.

What has been changed/improved:

- Pre-patched using Magisk v17.1 to pass SafetyNet even with the bootloader unlocked

- 90% of MTK apps have been replaced with better Google variants

- Most pre-installed Google Apps have been updated to the latest version (mid-September 2018)

- Removed Adups FOTA updater

Bugs:

- None noticed, please tell me if there is any.

Changelog (v3 20180917):

- Fixed issues with Google Photos

- Based on the GMS-certified August 2018 release

- Switched to a proper Pixel boot animation

- All sounds have been replaced with Google Pixel ones

Feature requests that require framework modifications won't be accepted, but i am open to any possible improvement if can be made to the ROM.

NOTE: Before you ask me, no, it isn't possible to reduce the saturation level without major modifications. I won't be touching the vendor partition neither adding any software as a workaround.
[Device Reviews and Information] RobBrownNZ:
Cases: I bought a Logitech Universal Folio with Bluetooth keyboard. It's got a nice keyboard, but it's clunky and hard to get the tablet in and out of. The worst bit is that one of the plastic clips presses on the tablet's power button continuously so I have to use the tablet upside down - which isn't a big problem but means I can't charge the tablet while using it and it annoys me to have the webcam on the bottom!
[Device Reviews and Information] YuriRM:
Is that the so called nose cam? Showing up your nostrils to your friends...
[Device Reviews and Information] RobBrownNZ:
Exactly!

... so anyway, I'm still failing to install OpenGApps and I am at my wits end. I'm sure I'm not doing anything wrong:

1) Install 0604 stock using SP Flash Tool (I've tried "Download" and "Format + Download" options)

2) Boot, do basic setup, enable OEM unlock

3) Into fastboot, OEM unlock, run "flash_all.sh" which automatically reboots when complete

4) Wait for LineageOS to boot, basic setup (this involves 2 glitches which resolve themselves after a few minutes)

5) Reboot into recovery, try to install OpenGApps --- fail, incompatible version for installing busybox, as reported earlier

Actually I'm not installing Magisk because I'm sure I was told it wasn't necessary... I'll give that a go and report back...

*** Done, installing Magisk made no difference. ***
[Device Reviews and Information] Alberto96:
Update your TWRP before installing Google Apps, i forgot to update it in the latest LOS build :)
[Device Reviews and Information] artemla:
I found a way to reduce screen saturation by disabling Miravision.

To disable Miravision you need to rename a couple of files and reboot tablet (root required).

Use file manager, that supports renaming of system files (Root Explorer, Total Commander or any other).

Files to rename:

/vendor/lib/libpq_cust.so -> /vendor/lib/libpq_cust.so.bak
/vendor/lib/libpq_cust_base.so -> /vendor/lib/libpq_cust_base.so.bak
/vendor/lib64/libpq_cust.so -> /vendor/lib64/libpq_cust.so.bak
/vendor/lib64/libpq_cust_base.so -> /vendor/lib64/libpq_cust_base.so.bak

You can revert those changes by renaming files back.

Note, that changing anything in Miravision settings will cause a black screen. Just reboot tablet to enable screen again. Running default camera app also causes a black screen.

Also, if you don't want to get a black screen again, you can disable Miravision app by adding this line to the /system/build.prop file:

ro.mtk_miravision_support=0

One more thing:

There is a special program to calibrate screen colors on Mediatek devices called MiraVision Tuning Kit. I found a couple versions of this program, but none of it supports Helio X20. If anybody knows where I can find MiraVision Tuning Kit for Helio X20 (MT6797) - please, let me know.

[Device Reviews and Information] Palm Trees:
[MENTION=2386505]Alberto96[/MENTION] - can you provide a list of the MTK apps you removed? Or do you have a master list of "Safe to remove/delete" MTK apps. The reason I ask is I'm both porting a firmware and also debloating/cleaning a stock rom for my Ramos MOS1 Max. Thanks :)

Try MTKExtractor Tool for extracting - it always works when other tools fail. I haven't unpacked Oreo roms though.

Hello to all.

I tried several times to install the GearLabs Rom but without success.

After unlocking the bootloader and after the procedure with fastboot, the tablet goes into bootloop ...

No problem when I install the last rom stock with sp tool.

I do not understand
[Device Reviews and Information] LUYULKMOIO:
ciao ivanfix,

with the fastboot method, I have the same problem as you :

target reported max download size of 134217728 bytes invalid sparse file format at header magi

then the process begins, but when he's done, the tablet goes into bootloop.

I also tested with the method "SP Flash Tool", the tablet goes into bootloop.

I had the same problem, with a tablet (Xiaomi Mi Note 2), it was the file "system" who had a problem, but not bizzardly for everyone.

Alberto96, I hope you will do a new update of the file "system", hoping that it will work.
[Device Reviews and Information] Jiai:

sorry Alberto96, it's my fault, I thought there was a GPS logo.

Your ROM GearLabs is very good, I also tested LineageOS_151_v0.2_Hi9Air_Fastboot.tar.gz.,

but as you said it is necessary that the project "treble" improves.

Now, I made a backup of the ROM GearLab, to be tranquili, once again thank you, for all.

For those who want to delete Magisk with the ROM GearLabs :

Use the latest version of Magisk-uninstaller (Magisk-uninstaller-20180719.zip).

The version (Magisk-uninstaller-20180710.zip) does not work.

Do not forget to reinstall the file boot (https://androidfilehost.com/?fid=5862345805528058494), if you have a bootloop.

Do not forget that this always involves risks, so if you are not sure, do not do anything.
[Device Reviews and Information] rippledrums:
You really only have yourself to blame. You followed the instructions, no one did that for you.

You either have a faulty cable for use with flash tool or you didn't follow the instructions all that well.

More than one person followed them with no problems or small fixable ones.

Guess it's always easier to blame others... :rolleyes:

Received another Hi9 air from Banggood as replacement for the defective screen. This one too had the same defect, so i wrote back to them with the video and photos and their reply was that they would refund me $49.99 and i would get to keep the tablet but the screen would not be under warranty. I replied back saying i would accept if they refunded $99.98, they then replied saying they can't do that so I've asked them to refund the whole amount once i send them back this one. Awaiting their reply. :rolleyes:
