I seem to have temporarily bricked my gtab. When attempting to nvflash restore all goes well until I unzip the .bat file that is needed. When unzipped it seems to change the format of the file and it won't run. I've done a search on this and have heard of other people having this problem so I know it is solvable, but I just can't seem to get it to work.
Any help would be much appreciated.
Thanks!
deadeye,
Roebeet's original 5.0.0 thread in Developer Forum has a bunch of info as well as several links to posts others of us have put together about dealing with this problem.
There also is another post near the top of Developer I put together on the USB .zip files needed and where to get them.
And I know I have written a bunch of help messages with detailed info to other
folks with your problem.
Check these out and let us know if you have questions. I'm sure it can be brought back, but may take some research and learning.
Rev
got it
Thanks for your response!!!
The new version of path is out, the social journal app, could anyone some how retrieve the .apk file, for some reason my Samsung mini never realises it is compatible, when it usually is.
(cannot post link as I'm apparently a noob)
(also is it possible to somehow make the store think your device is compatible?)
Thanks
Hey, i have the same problem. Can´t find the apk installer anywhere, maybe it´s because i´m using a custom rom. If I happen to find it i´ll let you know, i´ll appreciate it if you do the same.
Thanxs!
will do! as of yet, nothing
Hey, in case you haven' found it yet.

cheers! i was just about to send you the same thing but you got there first
Here's the deal. I'm trying to update Android on my Touch Pro 2 (this issue isn't TP2 specific, so don't stop here if you don't own one ) I cant boot into the build I just installed (It hangs on the "XDANDROID" screen) I think my problem is happening because I did not do a clean install. I figured it would work if I simply replaced the old files with the now ones from this thread now I'm at work and do not have the file available. My work has the downloads blocked from XDA Developers, so here's my question:
Can someone go download the zip/rar file in the first post of this thread and tell me which files are included in the zip or post a screen shot so I can delete all the extra stuff I have.
I'm also open to other helpful suggestions if you have any.
TIA
Hi guys,
I bought this tablet at the end of 2016. I played a lot with it, about 2 years. I sold it at the end of 2018.
These days i try to make some space in my hard drive, so i delete some files.
I have downloaded on 2016 many things about this tablet. Even now, Onda's official site is in Chinese and i saw that Onda Forum is down.
So i decided to upload here my experience, some instructions and service files about this tablet.
I will upload the files i have not at once, so before asking questions wait a little.
Enjoy
P.S : Sorry, now i saw that there is a limit on the size of files that a member can upload !! I wanted to upload the Original ROMS of this tablet (they are some GBs !!).
Please put the instructions
Hello,
I appreciate your good will gesture. I am interested in reinstalling the os on such a tablet ( I think mine is v5) and I can't find instructions and files for windows only the V820W_DUALOS_V5_32_1605279_20160602.zip(after windwos 10 reset I can't boot windows ,works only on Android). Hope you will continue, thanks.
Found solution to recover Windows 10 on tablet but lost Android
Hello , after some more search I found an interesting russian forum with many download links for this tablet. Here is a download link that contains many of the necessary files for Onda v820w from there:
........
For my case (tablet was reseted from windows options I presume, and was not able to boot anymore just some automatic repair started but did not work) , making a NTFS bootable disk with rufus and copied all the windows files from 10_V3.rar found in the download link provided and choosing ->"System image recovery"->then something about boot from EFI usb drive I remember. And it worked, it managed to reinstall windows and make it boot again by itself.
After succeeding this I became more confident and tried to update the Android form this tablet from 4.4 to 5 as I saw it has everything we need in the above link. After trying different versions of Manufacturing flash tool and Intel drivers for this tablet I managed to connect to it and make it take the provided image with Android 5 from fastboot menu when connected to laptop with the flash tool.
The only problem is it said it does not have enough space to flash system.img at around 84% on the Manufacturing flash tool loading bar. (strange as the tablet is empty,nothing on it, just default software).
Now Android does not boot anymore (haha, fixed something destroyed something).
The questions are:
-Can and how to use the other Android 5 images I found on the russian forum ? They are different type of backup files (with system.ext4.win type of files not .img files that the manufacturing flash tool expects).
From what I've read they are TWRP generated backups but my tablet has the default recovery.
-Can I convert the TWRP files to .img ?
-I found an TWRP recovery for this tablet (I hope) but I am not sure that if I flash the TWRP recovery it will not mess with the windows partitions already working on this tablet...
Here are the files I found and some english step by step tutorial for flashing the Android and a spanish tutorial for the Windows part of this tablet, on my google drive:
......
Edit: "To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages. After approximately 10 posts, you will be able to post outside links. Thank you for understanding!"
So I cannot post yet the links to images and the files but if somebody is interested I will sent in private massage. (If I will remember about this post in a few months , pretty lame the anti-spam rule...) Now I understand why who initiated this thread abandoned it...
RE: Links to Onda v820w windows files
Hi Olaruci,
I seem to have a similar problem to the one you and POWERSER have had. Please can you assist with the download links for this tablet. I can't boot the tablet into Android or Windows, only the system recovery option is available to me and it doesn't work.
Thanks :good:

Download links Onda v820w
Hello Grimm1,
I've sent the download links in private message.
I still did not manage to flash any of the system.img files ( I tried to unzip system.ext4.win images and change extension to .img but it's not working, not valid).
So I've changed the original recovery.img with the TWRP recovery found in the download link, and it works.
Now I have TWRP but with a small problem, it's in russian... now I try to find a way to change language (it's the materialized theme of TWRP 2.8 , and it seems it does't have a change language option)
Also windows 10 on PC needs latest versions of:
- Manufacturing flash tool (6.051)
- IntelAndroidDrvSetup1.10.0
- iSocUSB-Driver-Setup-1.0.4 or 1.0.5 (I THINK THIS IS THE MOST IMPORTANT to have latest version FOR THE MANUFACTURING FLASH TOOL TO SEE THE TABLET)
Also only connect tablet to laptop usb(in fastboot mode) AFTER opening manufacturing flash tool and AFTER selecting xml file and message "ready to flash" appears.
Hi,
I'm using an Onda v820w dual OS. I like this tablet and its dual OS capability.
I'm trying for days to find a way to change a few things but ondaforum is down so it's not easy now.
Once I succede I will give links and steps.
A first link where there is a lot to download : http://chinagadgetsreviews.blogspot.com/search?q=v820w&x=0&y=0
/!\ WARNING /!\ I did not test any of the software found on the link above so don't blame me if it screw your devices.
The first step was to install TWRP to be able to flash Android 5 instead of 4.4. The one I use is in russian for the moment so I use Google translate...
Anyway I just flashed Android 5.1 found on a russian forum a few minutes ago. For the moment the tablet is on the boot anim for at least 20mn...
I will tell you.

Hi Olaruci, thanks for the link it was a lifesaver for me
I only stumbled to one problem - for some reason I can not calibrate my Touchscreen. It works, but nither the Touch PG or MS Calibration software helped me...the calibration is just off (few cm gap). Did anyone had this kind of problem and what do you think I could do to solve this problem?
Kind regards to everyone who contributed this feed....it helped a lot.
Hey all!
A coworker gave me their old G Tablet months ago, and the only thing I kept finding was that it was very hard to find all of the tools needed to modify the thing. So many download links are down, etc. I just wanted to post these on here.
I will take them down if I'm stepping on anyone's toes. I will not help you troubleshoot. I am not responsible for any harm caused by the things provided here, and I cannot claim that they came from reputable sources because I can't even remember from where or when I downloaded them.
NVFlash notes:
I've included the drivers because they were harder to find. They're in usbpcdriver. I can't be bothered to reinstall them to find out which you need because frankly I don't care and you only have two or three options. Good luck.
By default nvflash_gtablet.bat flashes the files in its own directory. Just copy the files into where it's located.
The bootloader is contained on part9.img. If you want to flash CWM you will need to replace part9.img with clockworkmod.img for your particular bootloader. Just rename clockworkmod.img part9.img.
Hope this helps if anyone goes around looking to modify their device. Once again, please do contact me if you would prefer your work to be hard to find.

Link not open
I went looking through all my old files after I found my old G-tab. It was running barebones, stock android from viewsonic, and NOTHING worked anymore. Couldn't even browse the web or use youtube.
I found multiple custom ROMS (branch 1.2 firmware), stock ROMs (branch 1.2, don't have any 1.1 stuff, sorry!), along with TeamDRHs 350m partition prep file, NVflash, and USB drivers for Windows (can be found in the teamDRH 350 Prep folder). Everything you could possibly need or want to get your g-tablet back up and running again. I even used archive.org to look up teamdrh.com and gtablet for dummies old websites; so I could create instruction manuals for myself and those who need them. I just copy-pasted their how-to posts into word documents.
I was bummed I couldn't find MOST of these files ANYWHERE on the web. I was horribly surprised they were not even attached to the original posts here on xda. Maybe the get auto-deleted after a certain period of time or the original posts had links to their own website instead, sigh.
I hope these stay for a long time to come but if not, I have these files stored on 2 mechanical HDDs that I occasionally boot up to make sure they stay working. If anyone ever needs them, send me a DM. Hope this helps. Leave a comment with the ROM you decide to go with! Personally, I'm going with TeamDRH JB 5.2 as it is the 'newest' ROM I have. Hoping to get playstore and browser support using it at the very least. I'd just like to use my tablet as a web browsing/video streaming device again.
