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.
Hi, I have V80 Plus V3. Firstly this tablet is a garbage and frustration. I never recommend to buyers. I want to break this tablet. Onda's + gearbest's support is a big ZERO. For 1 month all apps are getting "unfortunately x app has stopped" and rooted + flashed twrp. also last time i installed google play services apk some apps worked but other apps like google play + account creation didn't work.
I tried to (uninstalled) reinstall google play services via flashing correct (x86) gapps package but google apps except play services installed. I wipe data etc on twrp, this time keyboard didnt work (only voice writing is working) installed. wiped everything rebooted, all issues continues! i took nandroid backup and restored not worked after chuwi rom.
I found a marshmallow rom for chuwi hi 8, 10, edited updater-script and flashed, NOW TABLET ISN'T LOADING.
Only i can enter to twrp + windows.
I found latest android firmware but tutorial is CHINESE!!! Also translated, found a note bottom: "this will delete windows"
HOW CAN I FLASH OR FIX ANDROID? Please help me.
I have a v820w wave bought recently, I went to do the formatting of it (windows) and the tablet entered an infinite loop in the windows installation.
It restarts when it reaches 67% and starts at 64%, this occurs more than 6 hours. I do not know what else to do to initialize or finish the installation. Nothing else appears.
Android works perfectly
hello guys.. I've been bit disappointed that my single boot android have just 8gb of space and two of the eight have been take by the system. I decide to go and change the android_data partition. create 64bit GPARTED live usb. Gparted will boot successfully if you choose the option to upload the live usb and run from ram.
After all boot I have been able see all the partition on my obook 20. The target was android_data where are stored all the apk and personal data...
extend the android_data partition i had to delete another partition which i was hope to create after... with picture taken before mess up with the partition I manage to get same size and location for the partition. so i hit apply.. first two changes have been successful but the next one fail and corrupt all partition on the drive. after I wanna create all partition as on the picture, but then i find the picture with detailed size of partitons is missing..
1... USB with at least 4gb.. 8gb recommended, Gparted , and some program to create live usb like a unetbootin or similiar.
2... someone who can boot gparted live usb and report or take picture of the partitions and size of them.
3... someone who can boot gparted and make backup of android_bootloader and upload somewhere for me...
once I get android bootloader back in my device I will be able to install android again...
You don't need to worry about corrupt or brick your device if you don't mess up or delete your partition..
Because i dont have android bootloader and is not easy or almost impossible to download it from internet, I'll keep mess up with the obook, install ubuntu or another os which can be booted from usb..
