First the Original ROM can be found at: http://www.onda.cn/Tablet_Supports.aspx?id=344 To download use JDownloader 2, copy the link and past on it that will work
There are 3 ROMs But attention the first one just works on the ONDA 80 SE V1 (You can check at the back bottom of the tablet)
What I've discovered so far is this tablet has a kind of UEFI BIOS, that means for you can enter on configuration to reset you will need an OTG Cable and conecta a keyboard on it. So I´m trying to discovery more about how to put another room on it, there is some tips on the files at the site but i´m not very sure how to do it. I just trying to do this because my battery status is really messy, I try to use root but to fix but it did not worked.
If anyone knows anything please let me know, I will continue researching and updating this topic.
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 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.
Hoping to get a little bit of help here. I bought my 16 gig, Onda V989 Air v3 about a month ago now and I've barely been able to use it.
1) The internal memory is separated into two partitions one of them being only 1.7 gigs. All my apps seem to be being downloaded to this partition instead of the bigger one, and as a result I have close to 10 gigs of space remaining in my total internal memory but I can't download any more apps. Does anyone know how to fix this?
2) I bought the tablet with the expection that I would be able to upgrade to Lollipop immediately. After a great deal of searching I still can't find any update to Lollipop for this device. Is there one available? If not, what's the best ROM / custom ROM and where do I find it?
3) I tried contacting Onda to either get a replacement (as I thought the memory partition issue was defect) or return the device and I couldn't get through. They would take a day to respond to each email and would give me the run around, repeating themselves over and over again (delete unused apps). Is there a better way of contacting these people, or do they really just not give a f*ck?
