I have Onda V919 air Dual OS but it's stuck in bootloop. I've tried to fix it by flashing the firmware but I'm unable to do so.
Maybe I don't have the correct firmware, I took it from XDA because I can't find it in download section of this forum.
Check attached files to see a picture of the back of my tablet and the error I'm getting when flashing.
Thank you for your help,
I have one of this tablets and have some troubles with it.
Something happened and it cannot boot. In fact it boots and shows the lockscreen for a second and reboot itself.
I try to enter recovery menu but there isn't any.
only calibrating mode and fastboot mode.
How can I enter recovery menu in order to do a hard reset?
Thank you in advance!!!
I tried with brushtool but it did not connect as it should.
How to: Prepare firmware, backup and resize Android/Windows without losing data (Onda V919 Air Dual OS V8)By dimadi
This is my experience with Onda V919 Air Dual OS V8 and maybe some of you will find useful info.
I don't use too much Android so I decided to increase space for Windows without losing Windows.
A. Sofware and hardware:
V919AIR Black Gold Edition 64GB dual system firmware 20151014_V1.0.1_V7 Andrews
V919 AIR dual system Black Gold Edition Windows 10 TH2 system image -20151119.part1-3
Android Flashing PARTITION TABLES
Macrium Reflect Free
Minitool Partition Wizzard
Paragon ExtFS for Windows
USB OTG HUB
Wireless keyboard and mouse combo
2 USB sticks 8GB
32 GB SDcard
USB to Ethernet adapter - I saved backups on NAS
a. Initial "factory state" eMMC backup with Macrium Reflect. ( C.2)
Also I prepared a bootable USB for recovery and I verified if it is bootable.
b. Prepared USB stick with Android firmware. ( C1)
c. Edited partition.tbl and transferred to Android USB. Cache from 1GB to 256MB, System from 1.5GB to 1GB and data from 16.5GB to 6 GB. (C3)
d. Removed chinese apps from Android system partition.(C4)
e. Installed Google Play.apk and customized Android and Windows.
f. Another backup with Macrium.
g. Installed Android modified with new partition.tbl (see note)
h. Restored, from the second backup( f ) : EFI, cache, system and data partitions for Android and 128 MB reserved partition, Windows(C) and Images partitions for Windows. I replaced partitions according their index number in ascending order. (C5)
i. Moved Images partition to the end of unallocated space and extended Windows(C) partition to include entire unallocated space. (C5)
j. Final backup.
Note: at this stage there is only Android partitions, the rest being unallocated space. To boot from Macrium Reflect USB I had to use "Power and Volume +" procedure in order to access the boot selection menu and switch to Windows. If the USB stick is not recognized the menu will show only Android logo.
Now my tablet has 5,8GB for Android data and 49GB for C:/ Windows.
In the same way, editing data partition in partition.tbl ( for example instead of 10000 MB, 20000 MB), could be extended the space allocated for Android.
During restaurations, dragging Windows partitions in unallocated space will give you opportunity to modify accordingly Windows and Image partitions to fill remaining space, using Minitool Partition Wizzard.
C. How I did:
1. Preparation of USB sticks for Android and Windows.
2. Backup of entire eMMC.
3. Edit partition table.
4. Debloat Android(remove chinese apps).
5. Restore Android and Windows after repartition without losing personalizations/data
All steps were recorded on Virtualbox machine using an backup image of eMMC but before that were applied on my tablet.
In the last video I messed backup images using one with the data partition and system partition already having 256MB respectively 1GB but the remaining 500MB were not allocated. Ignore unallocated space.
I have just bought the new V919 Air CH in mainland China, but I bricked it. I learnt from the forum that I can unbrick it by flashing its Bios. But there is no download of this ROM file from Onda.cn website, anyone has a V919 Air CH and can dump/copy its Bios for me? Thanks.
