[RECOVERY] TWRP 3.0.2-0 for Cube iWork8 Ultimate & iWork8 Air

Recommended Posts

This is my build of Dees-Troy's Team Win Recovery Project (TWRP) 3.0.2-0 for Cube iWork8 Ultimate (I1-T/I1-TD/I1-TWB/I1-TC) and iWork8 Air (I1-TF/I1-TBF). There's (at least) seven different batches of iWork8 Ultimate & iWork8 Air with slightly different hardware. Choose the right image for your model! I1-TWB image is reported working on I1-TF-20161108 and I1-TFB devices.

Do not mirror my builds! Please post a link to this page instead.

Prerequisites:
1. Download and install Intel Android USB driver (Windows) or setup udev rules (Linux).
2. Download and install Android SDK tools and platform-tools to get adb and fastboot.

Unlocking the bootloader:
1. Enable developer settings by clicking 'Settings -> About tablet -> Build number' several times. Enable 'Settings -> Developer options -> OEM unlocking' (not sure if necessary) and 'Settings -> Developer options -> Android debugging'.
2. Plug in your device via USB cable and open terminal window as an administrator (Windows). Boot device into bootloader by executing

adb reboot bootloader

You can also boot to bootloader by holding volume down button in dual boot menu and selecting to boot to Android.
3. Execute in terminal

fastboot oem unlock

Menu appears on the device warning that unlocking the bootloader will erase the device. Use volume keys to select the option to approve and use power key to confirm. It will try to format the data partition but fails because the bootloader is pretty useless (see below). Bootloader will be unlocked, though.

Notes about the bootloader:
Android bootloader is not working properly because of how Windows partition are named (not prepended with 'android_' what the bootloader expects). You can see a warning message when booted to bootloader and some bootloader functions are not working properly. You can't use fastboot to flash any image! Good thing is that you can still use fastboot to boot images. It also possible to fix this by booting the tablet to Windows and use something like 'GPT fdisk' tool to rename the Windows partitions (add 'android_' prefix). This is not absolutely necessary though if you're not planning to use fastboot to flash images.

Installing TWRP:
1. Download both TWRP recovery image and TWRP flashable zip from this post. Save the TWRP flashable zip to your device's sdcard. Save the TWRP recovery image to a place you can access in terminal window.
2. Change into the directory you saved the TWRP recovery image, boot to bootloader as above, and execute

fastboot boot recovery-twrp3020-cht_cr_mrd.img

3. Install TWRP flashable zip from sdcard once booted to TWRP.
4. Reboot recovery.

You can boot to TWRP by executing 'adb reboot recovery'. It's also possible to boot to recovery by booting to bootloader first (as above), using volume keys to select 'recovery' option and using power key to confirm.

If you've renamed Windows partitions (see above), you can use 'fastboot flash recovery recovery-twrp3020-cht_cr_mrd.img' to install the recovery image.

Stock ROM is encrypted by default which means data partition is not accessible in TWRP before you format it (select 'Wipe -> Format Data' - doing a factory reset is not enough). Important! This will erase your data including internal sdcard. It's recommended to do this once when installing dm-verity disabled/unencrypted boot image or flashing a custom ROM (CyanogenMod, Remix OS).

How to restore stock recovery:
1. Download zip below suitable for your device and copy it to your device's sdcard.
2. Boot to TWRP recovery.
3. Install zip in TWRP.
4. Reboot recovery.

Maybe your's is from another batch with slightly different hardware configuration. What stock firmware version does your device have? Kernel in this TWRP is from stock I1-T_V1.1_20160329.

I don't know, because i updated firmware. My touchscreen version is DXP2J1 

With that system.img file my touchscreen works perfectly: https://yadi.sk/d/J39Hkj-Wrt85g.

Here is also boot.img: https://yadi.sk/d/4dFDFvCnrrY4i

It seems your device is I1-TD. That firmware is I1-TD_V1.0_20160329 (vs. I1-T_V1.1_20160329 on mine). What is the original source for that firmware and do you have untouched boot/recovery images?

I can repack TWRP with I1-TD stock kernel later. My CyanogenMod 12.1 build is going to have the same issue so that will need a patch, too.

I really don't know. Inverted touchscreen problem appears in model with already installed dualboot (Win10 x64 and Android 5.1) by factory. When you try to update or recover device by firmware from Cube site (for version without Dualboot) because digitizers in device are different. There is no firmware for Dualboot-version except that custom rom.

That is a stock firmware for your device (not a 'custom ROM') but someone has modified the boot image, though.

Here's a TWRP that will work on I1-TD. I tested it on my device and touchscreen was inverted on mine as expected. You can't use anything from [HOWTO] Disable dm-verity, root & navigation bar mod for Cube iWork8 Ultimate thread (needs to be adapted for your I1-TD_V1.0_20160329 stock firmware) and CyanogenMod 12.1 needs a patch, too (I'll add it if/when there's another build).

Not exactly sure what you're asking but both my CyanogenMod 12.1 and Remix OS releases now have a patch for I1-TD variant.

I have Cube iWork8 Air (I1-TF).
After installing TWRP I1-TF and CM12.1 I had the following problems:
The tablet does not want to come out of deep sleep. Or go out after pressing the power button many times (up to 10 times). In Windows and the stock Android this was not a problem.
I installed TWRP I1-TD. The problem has completely disappeared.

Regarding work TWRP I1-TD on the Cube iWork8 Air (checked):
1. Installs the zip (set CM, GApps etc. with external SD).
2. Installs img (checked boot.img).
3. Work all Wipe.
4. Works file manager.
5. Error breakdown and formatting external SD. (It seems it did not work and TWRP I1-TF)

P.S. I am not prepared to discuss why this is so because I do not have enough knowledge. I described my problem and its solution.
P.S.S. Perhaps it worked just me. Other users can get a brick.

Just no! Android doesn't care what you have on your recovery partition. Trust me - this has absolute nothing to do with TWRP!

Thanks for your information and I trusted you what you got after flashing another TWRP.   But my situation is different, deep sleep problem appear on both Windows and Andriod, so I guess it is the Bios issue.   Anyway, thank you so much for your notice, pls. keep let me know when you get any new finding.

Did you modify system in any way while you were in TWRP? Dm-verity will prevent device from booting if even single byte is changed on /system.

Boot to Android bootloader by pressing volume down key in dual-boot menu. Try booting to recovery from the menu or use fastboot to boot TWRP again. Install the zip that disables dm-verity just in case.

Looks like another batch with different hardware. If you can get me boot.img and system.img (or system dump) for your device, I can add support for I1-TC in TWRP/ROMs.

Okay i will get the dump  for you. But i thought you need root the device to rip a firmware ? 

Can u tell me a good tutorial for ripping it?

And can i delete Windows and only flash Android ? Because Windows is pretty useless.

Yes, you'd need to have root in Android to dump boot/system or a custom recovery to make a backup. Easiest way is of course to download I1-TC stock firmware and extract boot.img and system.img from that. I can't download ~8gb from baidu and can't be bothered because of that anyway. If you can mirror those files, I can have a look.

You can maybe resize partitions and remove Windows but I doubt you'd still get rid of the dual-boot menu (no Android only BIOS available). You can see how this is done on other Cherry Trail tablets. I personally don't have any interest in messing with things like this.

okay i searched the web and only find one download link on baidu.. the speed is horible but i cant find another link... its takes about 10 hours but better then notihing .

i will get the files and upload it for you when it finish.

 

that with the dual boot menu is no problem for me . but when it is to difiticult maybe i dont go for it.
