---CHUWI TREBLE for noobs---

I Personally had. Issues gathering data about flashing a treble ROM on this tablet ,Information was scattered in different sites and within the pages of them. So I hope this will help you out random person .

---------------------------------------Pre.requisites.-------------------------------------

•Knowlege of SP Flash,Twrp, and how to use them

*Knowlege of Unlocking bootloader

•Knowledge Of ADB Commands( e.g. fastboot oem unlock)

•Knowledge Of Data encryption in Hi9 air ( found in 4pdu forums ) which is a different site)

•Download Stock Rom Files, Treble images(A-only 64bit,), Dencryption zip(from 4du forums) , and twrp

•A Computer

•OTG connector and Flash drive with the Unencrpytion Zip

NOTE:

I will assume you have read the 4pdu thread and you know how to remove encryption so I won't go in details what the files you need are in steps 10-15

Regarding the Commands I put in the steps bellow , the parenthesis is not included, but you should already know how and why because you should have done your homework on adb commands in the first place.

STEPS:

---------------------------------------------------------------------

1. Install latest Stock ROM via SPFlash and finish setup

---------------------------------------------------------------------

2 Go to settings and enable developer settings

---------------------------------------------------------------------

3 In Developer Settings Enable (OEM unlock) And (USB Debugging)

---------------------------------------------------------------------

4 Connect USB Cable ,and if prompted on the tablet ,check the box that says always allow.

---------------------------------------------------------------------

5Check to see if tablet is connected as adb device by executing command: (adb devices) in the terminal, if present it will show an ID of a device in some sort of random numbers.

---------------------------------------------------------------------

6 Execute command (adb reboot bootloader)- this will take you to fastboot mode

---------------------------------------------------------------------

7 Execute command (fastboot oem unlock)- unlocks bootloader

---------------------------------------------------------------------

8 On the tablet you will see a. Dialog to confirm unlock, press the volume-up button to start unlock, let it finish and execute ( fastboot reboot) - this will take back to OS. - DEVICE IS NOW IN ORANGE MODE-- this will show when you unlock bootloader during all future startups

---------------------------------------------------------------------

9.When you are back to android, Turn the Device off and flash Twrp via SP flash using download only setting

---------------------------------------------------------------------

10.After Flashing Twrp remove cable that connect to computer and connect flash drive to tablet via OTG adapter

---------------------------------------------------------------------

11 Go to Recovery by pressing vol-up and power button at the same time until dialog appears on bottom left. Choose Recovery by selecting it among the 3 with the Vol-up, and Vol-down to load it.

---------------------------------------------------------------------

12Once you are in Twrp it will prompt you a password. don't enter password and click cancel, swipe to allow modifications, go to install and click select storage at the bottom right select the USB-OTG

---------------------------------------------------------------------

13 Select the Decryption zip and flash it

---------------------------------------------------------------------

14 Go back to home and Click Wipe and on the bottom click Format data , if prompted confirmation ( might tell you to type (yes) ) then type it. Proceed to format data(P.S it might also tell you whether or not you want to install Twrp app ,it just depends if you want to, )

---------------------------------------------------------------------

15 Go back to Home , select reboot , and then click recovery- it will boot you back to twrp

---------------------------------------------------------------------

16 To check if decryption is successful , when you reboot back to Twrp you won't be prompted a password and it will instead gostriaght to (swipe to allow modification) . If not ,repeat from step 12

---------------------------------------------------------------------

17. In home select reboot ,click bootloader

---------------------------------------------------------------------

18.remove USB OTG and connect tablet to PC

---------------------------------------------------------------------

19 On PC type Command (fastboot flash system) , add a space, then drag and drop your preferred TREBLE ISO . It should look like this

(fastboot flash system TREBLE.IMG) , execute the Command and wait

---------------------------------------------------------------------

20. Once the command is finished ,, execute ( fastboot reboot) --- this will reboot your device into your new TREBLE ROM.

---------------------------------------------------------------------

((((((( to remove treble ROM you just use SP FLASH TOOL, or if you want to install another treble ROM you just go to twrp and make sure it is still decrypted , if not decrypt it again and perform a FORMAT DATA, Finally you flash Treble image via ADB terminal Again.))))))

-CONGRATS!

BTW our tablet apparently works on all pph Treble images tested as of version V25. Given of course it is( A-only 64bit)

I hope I helped you all , BTW my chuwi suffers from constant reboots, and sad to say I think it is definitely a hardware problem,
