Always safe remove the card from the computer.
Always format the card before use.


READ THE INSTRUCTIONS!


If you proceed, YOU ARE DOING IT AT YOUR OWN RESPONSIBILITY!!!

I will not be responsible for any damage caused in your tablet by using this ROM.


Warning: This ROM will completely wipe your tablet. Please backup your data first!

Dear all,

Here is the fifth version of my custom ROM based on Onda's release 1.1.0 for V975m.


ROM Features

- Based on ONDA's official 1.1.0 release.
- No chinese apps.
- Properly rooted with Chainfire's SuperSU 1.94.
- Default language is en_US
- Default timezone is Europe/Athens.
- Updated google apps from bundle gapps-jb-20130813-signed (from goo.im).
- 4GB /data partition (the space you install your apps in), from 2GB original.
- Removed ONDA default launcher and replaced it with NovaLauncher.
- Skype version 3.2.0.6673
- Disabled 3G layer to save battery. If you need to use a 3G USB stick, then change in build.prop the property hw.nophone=true to hw.nophone=false.
- Disabled OTA upgrade (by changing the update host to 127.0.0.1).


Installation instructions

Case A - Upgrade install

If your tablet has already 4GB /data partition (meaning your are already running one of my roms), then follow this procedure for the upgrade:

Follow this steps exactly:

1- Extract the .rar file of the ROM. You will get these files:
aml_autoscript
factory_update_param.aml
recovery.img
u-boot.bin
update.zip
2- Put an SD card of size up to 16GB in card reader.

3- Format the SD card with SDFormatter version 4 (hint: run this program as administrator).
You can download it from here: http://www.ondaforum.com/topic/148-sd-formatter-40-for-sdsdhcsdxc/

4- From the files you extracted in step 1 copy ONLY these files to SD card:
factory_update_param.aml
update.zip

5- Safely remove the SD card from the computer (Very important!).

6- Power off the tablet by pressing <Power> button for 20 seconds.

7- Put the SD card into the tablet's card slot.

8- Press simultaneously AND HOLD the buttons <Power> and <Volume +>.

9- When the green droid appears (or after about 5 seconds if no droid appears) release ONLY <Power> button. Keep pressing <Volume+>.

10- After about 1-3 minutes you will see the big droid with the spinning cube. Now release the <Volume+> button.

11- When the update finishes, the tablet will reboot. As soon as you see the ONDA logo, you are in business.


Case B - Clean install

If your tablet has 2GB /data partition (meaning your are NOT running one of my roms), then follow this procedure for the upgrade:

Follow these steps exactly:

1- Extract the .rar file of the ROM. You will get these files:
aml_autoscript
factory_update_param.aml
recovery.img
u-boot.bin
update.zip

2- Put an SD card of size up to 16GB in card reader.

3- Format the SD card with SDFormatter version 4 (hint: run this program as administrator).
You can download it from here: http://www.ondaforum.com/topic/148-sd-formatter-40-for-sdsdhcsdxc/

4- Make the SD card bootable with SDcardMaker_uboot tool.
You can download it from here: http://www.ondaforum.com/topic/29-sd-card-maker/
IMPORTANT: Select the u-boot.bin from the ROM you extracted in step 1.
Format the card when asked to by the SDcardMaker_uboot. Format must be FAT32 with 32KB cluster size.

5- Copy all the files you extracted in step 1 to SD card.

6- Safely remove the SD card from the computer (Very important!).

7- Power off the tablet by pressing <Power> button for 20 seconds.

Check in build.prop the entries for:

ro.product.name

ro.product.device

ro.product.board

ro.build.product

ro.build.description

ro.build.fingerprint

V1 is k12_MA975M8

V3 is k12_MA975M8_B

The installation script checks for these values.

Now, if flash works, you do not need the patch. If it fails, then you do need it.

For the kernel I do not know. It is the stock ONDA kernel.

Bysubox is installed (actually pre-installed by ONDA).

For the kitkat beta:

Warning No file_contextsThis package is for "k12_MA975M8" devices; this is a "fiber-ondama975q92035"

Look at the serial number printed in the back of your tablet. If the 9th and 10th characters are V1 then you have V1 hardware. If they are V3 then you have V3 hardware.

Flash the 1.0.9 version for YOUR hardware.

You can also flash one of my roms, for YOUR hardware.

Do you have some ideas?

Can you install a prop editor and tell us these values from /system/build.prop?

ro.product.device

ro.build.product

Or install DeviceInfo from market and tell us the board,device and model it shows.

Finaly, do you know which rom is now installed in your device?

I'm afraid you should contact your reseller. This is completely strange.

Anyone else with the 16GB version, can tell us the device name he sees in DeviceInfo?

Your tablet is NOT a V975m. It is a V975.

Enr1988 All of that stuff (setcpu etc) won't work. From what I know/understand, kernel doesn't allow it.

      I have an Onda v891w CH V1 with a quad core Z8300 that runs an English Windows 10 and Android 5.1. Default OS is Android. And the problem is that the Android doesn't boot. It gets stuck on the animated Onda logo screen, it keeps running the green color through the logo for hours, never starting Android. I am able to enter Fastboot by pressing volume down and power at boot and have been able to wipe user data and reset to factory defaults in Recovery, but still no luck. I can get to the OS selection screen by pressing volume up and power at boot, but I have no way to make a selection there as no inputs are accepted/working, so I can't test booting into Windows either. From everything I've read so far, I could reflash te BIOS or ROM in DNX mode if I just had the correct files. Could anyone point me to the correct BIOS for a v891W CH V1 in English please? Any and all help would be greatly appreciated, as support from the vendor has been limited to "try a different power charger"
    • By Falcionx
      Disabled the USB ports by mistake now need to reset the bios ... besides that Windows 10 was installed there began to automatically update, and touch screen barely work I have a card reader, and I'm able to run a BIOS update so if someone has a BIOS I would be grateful

    • By ntggl19
      Hello, can someone tell me where i can find the bios for Onda v919 air CN V3?
