How do I Remove Windows on Dual Onda Tablets?

Recommended Posts

Hi!

I have a Onda 919 3G Dual 64GB.

I was wondering if it's possible to erase the Windows and use all space for Android, it should be the same on all Onda Tablets right?

How do i do that? Is there any guide?

thank you.

To keep only android ,you need to modify the following number in red in the file : partition.tbl

add -b 6455336 -s 15040512 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

The new number should be smaller than (windows partition space +15040512)

how to calculate the number: x M*2048

I'm not following here, can you give me the example of how you calculate the number for a 64 GB system?

Go to the firmware folder,  open partition tbl and change the last "add" line to number x gigabytes x 2048

Eg

add -b 5406760 -s 44040192 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

This 44040192 is a 21gb partition (21x1024X2048) in bytes

      Hey there. I just want to share my recent experience with flashing windows images on a V919 Air tablet. 
      The reason for the reinstallation was that after a system reset in windows 10, things went wrong with the touch screen. It registered touches at completely wrong places and orientation. I tried calibrating it using the buildin windows 10 utility and it did nothing. 
      The step I struggled with for several days was that none of the system images downloaded from the official site was able to boot on this tablet. Eventually I stumbled upon an old web page with a 32bit windows 8.1 image and it worked. The system was then upgraded to windows 10 and everything appeared fine. 
      If you encountered similar diffficulties in booting the images from Onda, see if the images are 64 bit. All the ones I initially downloaded are 64 bit, and they are not recognized by this tablet. Only 32 bit UEFI files can boot. Same if you want to use some windows PE images, 32bit ones are needed. 
      Based on the serial number, mine is probably a V5 version of V919 Air 64 GB DualOS.

      After getting no support for this tablet (not a moan about  this forum) I decided it was time to sell mine on..
      Lost a few pound in selling it but it was frustrating to have a device that you just could not (I never found out) restore to factory status,, I'm sure there is a recovery partition on the SSD but no idea how to activate it. Pity; there's a lot going for it.. screen was very nice.
      Lesson.. buy something with at least some support.. 
      I just bought a Lenovo Yoga.. lost for choice on support yet not  expensive if you get refurb model with 12 month warranty. Anyway thanks to the host of the forum.. and adios.
