Only issue is Safetynet

Please. I Have a big problem on my Chuwi Hi9 Air rooted.

For my mistake. I pressed volume down and power instead of volume up and power button. A Chinese menu has opened. Not knowing what to do, I pressed power and started doing all sorts of things. I forced the shutdown but now it doesn't read sd cards. What can i do ?

Thank you so much
[Device Reviews and Information] amg314:
This, probably, is the Chinese "stock" test menu (although it would be better to post a screenshot).

Volume down / up allows you to move around the hieroglyphs.

The bottom line is the 'Reboot to system'. You should activate it by pressing Power button.

Hello everybody!

I have lost my backup of NVRAM.img. :(

Could anybody provide me with a copy for Chuwi Hi9 Air? It should be fairly easy to create for a working tablet using Smart phone Flash Tool. There is the menu "Readback". Just click on "Add". Then save to the file nvram.img. Enter the start address 0x000000000ab00000 and the size 0x0000000000500000 in region EMMC_USER.

If you could help me out I'd be really grateful. It should be a European model though because of the basebands. :highfive:

Thank you very much.
[Device Reviews and Information] amg314:
You should inform on your ROM release-keys first.
[Device Reviews and Information] darkwindhowling:
Hi, thank you for that quick reply. It's the stock ROM in the version 20181122.
[Device Reviews and Information] amg314:
URL on your ROM:

https://yadi.sk/d/mlnrJd4HN48rMA

BUT, there are NO NVRAM.img (see list attached((((

You should ask 20181122 users send you nvram partition copy.

In my tablet (under other ROM version) nvram is /dev/block/mmcblk0p19

You can also extract nvram.img from ROM above using ReadBack feature of SP Flash Tool.

On your own risk!
[Device Reviews and Information] darkwindhowling:
Hi amg314!

Thank you for your continued support. Would you be able to create that nvram.img? Maybe the nvram of your scatter file will match my requirements because it should be independent of the ROM version. If you have smart phone flash tool and a scatter file for your ROM that should be enough. If you open the scatter file with your text editor and search for the partition name nvram you should be able to find the data for physical_start_address and partition_size. These values are needed for the smart phone flash tool in the menu "Readback". The values I get from my scatter file are

physical_start_addr: 0xab00000

partition_size: 0x500000

In smart phone flash tool's Readback you click "Add" and tell where to save the backup. Name it nvram.img. There after it will display a form where you have to select "EMMC_USER" and enter the start address and the size. Enter the values you have noted from your scatter file. You have to have the USB-Debugging option enabled on your tablet. Then you have to shut down your tablet and connect it to the computer using the usb-cable. As soon as you turn the tablet on again it will read from the tablet the section where the nvram is located and write it to the designated file. In the end it should have a size of 5.242.880 Bytes.

Maybe you can help out with this even though you have a different ROM installed on your Chuwi Hi9 air.

Thank you very much.

Hi fellas, I just got this tablet a couple of days ago. I've been playing around with it and I like it so far, except for two things:

1. It takes forever to charge....

2. Volume is very low

Any workarounds for such issues?

I read the thread before asking but couldn't find any relevant information or solutions.

Need help for unbrick

Hello,

i tryed to install TWRP recovery but seems something went wrong, during installation process via fastboot i did not noticed any errors, but now tablet is in boot loop with message.

Orange State

Your device has been unlocked and can't be trusted

Your device will boot in 5 seconds

i assume i need somehow to get back into fastboot mode, but Volume UP + Power does not work.

Is there still hope that my tablet isnt brick :)
[Device Reviews and Information] amg314:
'Orange state' mean that your bootloader is unlocked. Do not worry on this matter))

Switch Chuwi to PC with USB cable (USB drivers and adb binaries are needed) and run adb session:

https://dl.google.com/android/repository/platform-tools-latest-windows.zip

adb devices

adb reboot recovery

And tell us the result.
[Device Reviews and Information] spameris:
adb devices

does not detect anything. I assume i need somehow get to fastboot mode with correct key combination, to reflash TWRP. Vol down + power and Vol Up + power does not work :(
[Device Reviews and Information] amg314:
It looks like you did not switch USB debugging option in Developer Option menu((

To flash TWRP to our tablet there are two ways - common (fastboot) and MTK specific - SP Flash Tool. SPFT flashing need USB drivers installed, TWRP *.img and some luck.

Try check in SPFT scatter file and TWRP *.img file only, switch tablet power off, press Download only in SPFT and AFTER that connect Chuwi to PC thru USB cable.

OK, now seems at least my tablet isnt brick anymore at least i can access TWRP . Had some adventures with SPFT crashing on ubuntu 19.10... crashed due to some errors related to GUI. But i managed to flash TWRP from command line.

now looking which ROM to install... lineage os 17.1 ?
[Device Reviews and Information] amg314:
TWRP is a big step in building your own custom Chuwi))

I was impressed with your work with SPFF from Linux terminal))

As to ROM - this is a difficult choice.

I use old 20180604 + Magisk 20.3 + microG (- gapps)).

Hi, thanks for the explanation, I've tried what you said before

1. I've replaced the DA in the flash tool folder

2. When i open the flash tool and try to load the scatter from the rom folder, it gives me an error about the scatter file.

Are you able to load the scatter file from the stock rom folder without any errors?

Three days ago I flashed LineageOS 16 (Android 9) on my Chuwi.

https://theupgradeguide.com/2020/01...0-on-chuwi-hi9-air-lineageos-16-how-to-guide/

My impressions:

Pros:

1. No Google at all (including no gapps).

2. Minimum apps preinstalled

3. Pretty nice interface))

4. No hardware issues found: camera, Wi-Fi, so on works fine

Cons:

Battery drain problem (battery saver ON needed)

Charging boot animation screen issue: no digit level and no green visual level during charging of PowerOff tablet((

Installation details:

Extract System.img from *.xz archive (I used rar for Android).

Make new folder on SDCard (Lineage, for example)

Copy to it main *.img, *.zip, *.apk and backup files (for Jota+, AquaMail, etc)

My complect:

boot.img, magisk.zip, Magisk-uninstaller-20200110.zip, main-microG.zip, TC.apk, keepass dBASE, etc.

I made NandroidBackup, when wiped factoty reset, flashed system.img, magisk.zip, microG.zip, reboot to system.

Magisk, microG and main apps work fine.

Hi all.

I've tried to root my tablet, but I'm not able to install magisk.

After enter recovery my internal storage and sd card don't show any file and also show 0MB.

What's wrong?

Tks
[Device Reviews and Information] amg314:
You should inform on ROM version and TWRP version first.

IMO, the 3.2.2.0 TWRP from OP is most suitable.

If you use last version of stock ROM, you should decrypt your data area before flashing Magisk.zip.
[Device Reviews and Information] rimsilva:
Yes, it's TWRP 3.2.2.0 and i'm on stock ROM.

It's true that I've password request, i've removed PIN request on boot, but the request it's always there, problably it's because of the decrypt issue, I will look at it.

thanks
[Device Reviews and Information] amg314:
On your own risc!

You will Format Data region, you will lost all pictures, music, video etc.

To decrypt data area on Chuwi Hi9 Air:

Copy all needed data to PC/cloud/SDCard, so on.

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

1. Make Ready_to_All folder on external SDCard((

Copy to it remove_encryption_97.zip, Magisk-20.3.zip, Magisk-uninstaller-20200110.zip, TitaniumBackup.apk, your_best_launcher.apk, TotalCommander.apk, your mail.settings.backup

TitaniumBackup backups folder and so on.

2. Boot to TWRP, do not enter password, go to Install menu, Select Storage --> External SD,

select Ready_to_All folder and remove_encryption_97.zip in it.

Install remove_encryption_97.zip

3. Move to Reboot -> Recovery (NOT to System!!)

4. Move to Wipe --> Format Data

5. Move to Reboot -> Recovery (NOT to System!!) You will not see any password request now!

6. Install --> Magisk20.3.zip

7. Reboot -> System

Your tablet will reboot twice, wait booting for a long time, like at a new device.

8. Rebuild your tablet using SD Card apps.

Zip to decrypt:

PS If tablet run OK, reboot to TWRP and make Nandroid Backup.
