  1. Hi all, Yesterday I did a fresh windows 10 install, is all working, but the touch screen seems to be not calibrated, is working but rhe pointer appears not exact under my finger, but a few cm down-left my finger. I tried recalibrating the touch screen with windows tool, tried other drivers and even restoring the driver from the original onda windows installation that came with tablet (I maked a backup of drivers installed before formatting), but is the same, working but not pointing the exact pussing zone Any ideas of what to do? My tablet is the v5. Thanks! EDIT: GUIDE TO GET FRESH WINDOWS 10 INSTALL WORKING CORRECTLY IN THE NEXT COMMENTARY
  2. For those who accidentally refresh their own windows OS on Onda V820W and experiences bootloader loops problem, and need to reinstall back the system. This guide will help you on how to install fresh Windows 10 (64bit) to Onda V820W chinese tablet V3 without Android installation. If you have Onda V820W tablet V1, you should install 32bit (x86) windows installation, you can refer to Juspe's guide here. Not sure which Onda V820W model are you? Check on serial number at the back. Look at the 9-10th line. FYI: You will be not able to install x32 (bit) into Onda V820W V3, because it can only bootable to x64 EFI. If you do, message that appears is always this: Fail Could not locate \ EFI \ Boot \ BOOTX64.EFI And you can't install using normal PC windows 10 x64.ISO into this tablet, I have tried that. There is no 64bit drivers available on internet. Requirements: - USB drive (at least 8GB) - USB OTG and USB Hub (to connect USB drive, keyboard & mouse) - Full-charged battery (please charge atleast 2-3 hours) Steps: 1. First we create bootable USB drive with Windows 10 x64 in it. You need to use Rufus (install latest version) download: https://rufus.akeo.ie/downloads/rufus-2.10.exe You may want to check this tutorial, the procedures is also same. 2. Download these two part files for V3 Windows installation. (I was looking for this Win10 x64 image for days and found these links on russian website) V820W_CH_DUALOS20160121.part1.rar V820W_CH_DUALOS20160121.part2.rar 3. After files are downloaded, extract all the files into a folder on your PC using WinRAR (for example, C:\temp\tablet) 4. Plug in empty USB drive (8GB space - the extracted files consist over 7GB of image) 5. Navigate to extracted folder (for example, C:\temp\tablet) 6. Open Rufus 2.10 (You also can use UltraISO_v9.5.2.2836.exe, but it's in chinese program. refer here http://www.ondaforum.com/files/file/576-win81-system-installation-tutorial-_ipdf/) 7. Select your USB device with "GPT partition scheme for UEFI". Not MBR partition scheme. 8. Set your USB drive file system into NTFS (default FAT32 will be unable to copy large files more than 4GB) 9. Name your USB drive volume label to WINPE (This is a must! So it can be detect during installation scripts) 10. Open and select ISO image using CD icon with "win10PE_x64.iso" located on extracted folder. 11. Now press Start button to create bootable USB drive. 12. Once completed, you copy almost all files from extracted .rar folder into bootable USB drive named WINPE (replace and merge files, if you have insufficient storage, deselect Sources folder and copy other files) Boot(Folder) EFI (Folder) images (Folder) scripts (Folder) sources (Folder) bootmgr bootmgr.efi Windows Installation 13. Plug in OTG + USB Hub -> plug bootable USB drive + keyboard + mouse (optional) 14. Power Onda tablet and press ESC (repeatly until it shows "Esc is pressed"). BIOS will open. 15. Select Boot Manager, and there you should see your USB device. Select EFI USB DEVICE and press ENTER 16. Wait until it load windows installation open. You should see some command prompts that will format, copy, mount and install some files. It will take some time. The real windows installation should start after all command prompt windows. -----------------------------------------------------If everything went OK, skip this part-------------------------------------------------------------------------- If command prompt fails to continue to installation and you get something like this: 1) Find out what is the drive letter of your usb stick. In that picture you can see that U-WINPE has letter D. 2) Set command prompt variable WinPESource to that drive using command (remember to change D to your letter). Check the picture! set WinPESource=D:\ 3) Now that path should be OK. Launch Main.cmd by writing the next command and hit ENTER. (remember to change D to your letter) D:\Scripts\Main.cmd 4) Now the installation should continue. If not, please post and ask for help! Guide installation continues 17. Now you are in the (chinese) windows installation. Scroll up or down until you can choose English option. (You can use Google Translate app on phone to find out what each text means. Use it by selecting to translate from China -> English and take pictures from menus and dropdown lists and so on.) 18. After the Windows is installed change language to english and install all updates. Now you can proceed to install your standard programs. Everything works now for me! Windows 10 install went smoothly and no errors and no driver problems. If you got driver problems: x64 driver Touch Hope it helps!
  3. Hello, I just managed to install Windows 10 without Android to V820w and still got more than 12gb of free space on C:\ With this guide you can install fresh Windows 8.1 with Bing to Onda V820w tablet without Android installation. This way there is a lot more space available. Requirements: Thanks to all images goes to fjperezj Steps: 1) Remove all partitions except EFI (first), Recovery(second) and Windows partitions using Windows Drive manager (right click My Computer -> manage). 2) Now you should have only those three and some unallocated space. You can merge all those to one partition, if you like. 3) Now we create bootable USB with Windows 8.1 in it. I used this tutorial myself: http://www.ondaforum.com/files/file/576-win81-system-installation-tutorial-_ipdf/ Download these two files (Shouldn't matter that it is for V1 because we have no Android. I had V3 and everything works) ---> http://www.ondaforum.com/files/file/574-v820w_v1part1rar/ ---> http://www.ondaforum.com/files/file/575-v820w_v1part2rar/ 4) After files are downloaded, extract all the files to a local folder on your PC (C:\temp\tablet for example) 6) Plug in a USB stick that has 4 gb of space5) Navigate to that folder (C:\temp\tablet for example) 7) Open UltraISO_v9.5.2.2836.exe. Now a chinese program will open. Next steps will be guided in pdf file that I linked earlier. So open it too! (http://www.ondaforum.com/files/file/576-win81-system-installation-tutorial-_ipdf/). 8) Open a file with it that was in archive called "Win8.1_x32_PE.iso" using open icon 9) After it is opened, click 3rd menu on top and select 4th option. Check pdf for guide! 10) Select your memory stick and check the left checkbox (there are two) Check pdf for guide! 11) Press 2th button on bottom from left corner. Check pdf for guide! 12) After formatting is done close the UltraISO. Now the usb stick has 212 mb FAT partition for booting and the rest is NTFS for big files 13) Format the usb stick from My Computer to NTFS. NOW THE IMPORTANT PART: Name the stick by "U-WINPE". 14) Copy almost all files from .rar archives to usb stick: Windows installation 15) Plug in USB hub to Onda tablet -> plug USB stick and keyboard to it 16) Start tablet and press ESC -> Bios will open 17) Select Boot Manager and there you should see your USB device. Select it and press Enter! If there is no USB device (only Windows, Android and Efi) check the name of the usb stick. THE NAME HAS TO BE CORRECT. 18) Now windows installation will open and you should see some command prompts that will format, copy, mount and install some files. It will take some time. The real windows Installation should start after all command prompt windows. -----------------------------------------------------If everything went OK, skip this part--------------------------------------------------------------------------If command prompt fails to continue to installation and you get something like this: 1) Find out what is the drive letter of your usb stick. In that picture you can see that U-WINPE has letter D. 2) Set command prompt variable WinPESource to that drive using command (remember to change D to your letter). Check the picture! 3) Now that path should be OK. Launch Main.cmd by writing the next command and hit ENTER. (remember to change D to your letter) 4) Now the installation should continue. If not, please post and ask for help! -----------------------------------------------------Guide continues---------------------------------------------------------------------------------------------19) Now you are in the (chinese) windows installation. Use Google Translate app on phone to find out what each text means. You can use it by selecting to translate from china -> english and take pictures from menus and dropdown lists and so on. 20) After the Windows is installed change language to english and install all updates. After that Windows 10 banner will be shown and you can install it. Everything works now for me! Windows 10 install went smoothly and no errors and no driver problems. If you get driver problems: Download correct drivers for you tablet version from downloads page: V1) http://www.ondaforum.com/files/file/325-v820w-v1_win81_x86_driversrar/ V2) Will be added here.. V3) http://www.ondaforum.com/files/file/453-v820w-dualos_drivers_installv3-version-20150520rar/ 21) Remove "Windows.old" folder from C:\ if you have taken all the old files. This way you can get more space! It is the old installation backed up for safety. Hope it helps somebody!

  10. I just purchased a v820W from someone down the street. It has windows 8.1 on it. How can I positively identify if this is just a windows or if it is capable of dual OS? Also, how can I tell which version (V1, 2, 3)? I am excellent at flashing ROMs or changing BIOS and installing operating systems. I just do not want to flash to dual boot BIOS to the device if it is only windows. Good comments or links or anything to start would be great. Thanks.

  25. Hi everybody, I'm new on this forum. Recentrly I bought an Onda v820w, it's very good but it has some audio issues. The tablet produces a persistent white sound from back speaker and also when I plug in headphones' jack I ever hear some interferences in the audio, which is very annoying. Is there anybody which have/had the same problem? Thank you for your attention!
