How to update install ROM v972 firmware using the automatic update.
You will need to use a Windows PC to install the ROM using the Phoenix Suit version for your ROM.
Once you have updated your tablets firmware a few times you'll be an expert and only need a few steps as a reminder if anything.
Start here after you have finished with your downloads from above.
- Shut down your tablet by pressing the power button in for 10 to 20 seconds. Uncheck the "Next Fast Boot" option.
If your tablet starts to boot then keep the power button press until it shuts off.
- Download the correct version for your tablet. The version number is on the back of your tablet to the right of the serial number. (SN: 1234 V1)
- Extract the RAR file and you will find the following.
- V972 Core4_vX.X.X_vX.img
Example, Press the power button then release it, pause for one second and then repeat the Press and Release.
If your PC fails to connect at this point you will see a help message. Repeat the steps 8, 9 and 10 until your PC connects.
Some of the download ROM version have factory root while others you will need to root your Onda tablet.
This is the easiest thing to do thanks to Onda for making it a simple upgrade.
You will see the progress bar start to populate when your upgrade has started.
Onda Root OEM:
The root.zip created by Chainfire.
Root your OEM ROM.
Before you do anything below check to see if your ROM is rooted by default.
I have found most all of the newest ROM releases (3.x and newer) have root.
If you need to root the OEM the instructions are below.
Root Installation Steps:
- Download the root.zip to your tablet root.zip.
- Tap on Update.
- Tap Local Update
- Tap your back button to go to your sdcard root or to your download folder.
- Select and tap the root.zip
- Start the OTA update tap on Update.
That's it, you should be set to go.
Test it with any application online. I know Weather Underground will not recognize the Onda v972 as a compatible device until you root it.

This part is for those that know how to upgrade their firmware and know how to root their device.
I want to point out any major differences between the firmware upgrades here.
Removing Chinese Apps: (I have the same post here as well.)
I use Titanium Backup Pro to uninstall apps that I don't need. You can use the free version as well.
It's as easy as 1,2,3 and 4.
- Run Titanium Backup and backup everything before you begin.
(pro or free as long as you have root)
- Tap Backup/Restore
- Tap the application you want to remove and tap "Wipe Data" then tap "Un-install!"
- After you have un-installed all the apps you don't want shut down and restart your tablet a couple of times.
Here's the image guide to using Titanium Backup to remove any hard to remove application. This also go for MobileIron and system apps. (Be very careful)
1. Select the app you would like to remove or uninstall.
Next, Wipe the Data first.
Next, Uninstall the app.
Next: You will see the app lined out.
Next: Be sure you see the app lined out. Do not delete the backup before you know your tablet will operate normally without this app.
Next: If you have problems with your tablet after removing the app you can reinstall the app using restore.
Next: Select Restore App+Data (we wiped the data)
NOTE: I have tested and tried to install the wrong ROM hardware versions and found the ROM will not load. This means you will be OK if you downloaded the wrong version ROM.
If you installed a bad ROM or a ROM from the developer that is using the SDK kit which doesn't have HDMI enabled you should replace that ROM with the default factory ROM listed here.
I know, it's in Beta but you've got to see it, so cool. I'll send up screenshots after I remove all the apps.
Tech Note: Some have stated the download from Onda.cn is out of beta and final.
I for one hope this is not the final and that Onda is still taking feedback.
I had updated my v972 v1 the other day and have had great experiences with it except for the battery life.
My 3.3.2 v1 would allow me just over 4 hours of solid screen on apps running time.
The 4.4 v1 offered just about 1.75 hours (105 minutes) the 3.3.x versions allowed me to watch a couple of full length movies and now that's not happening.
My speed tests also dropped from 18,xxx to 11,xxx.
Seemed to be sluggish with some apps as well.
Charging from my USB port that did well from my desktop computer doesn't even keep the battery levels when connected.
One big thing I noticed was that it wasn't rooted and the classical methods to root didn't work.
Onda has always made it easy to root the office ROM without having the SDK ROM. The SDK for the A31 from what I understand has issues with the HDMI output. I use the HDMI often and root.zip from this site has always worked just fine.
I'll update a review page for the KitKat 4.4 Android system and layout some of the issues I'd like to see corrected in the Onda v972 ROM.

I've noticed a couple of things different between 2.0 and 3.0 and between 3.2.1
Note: You should also Google user experiences with the different versions.
I have had great battery, HDMI and WiFi with the firmware version 2.0 it is running Android 4.1.1.
I have had good to poor experiences with the 3.2.1 related to battery life. I do like the Android 4.2.2 and the 2 hours less on battery is my trade off.
Here are more notes mostly repeating what is above.
By far this is the best tablet I have tested.
With the new 2.0Ghz Quad Cores coming to market I'll be testing and using the faster models.
I'm going to be guessing that the battery life might be an issue.
I have a few solutions setup now, 2 solar charging stations and a battery pack. But, if it can last 4 hours non stop remote desktop with the server I'm ok with charging it during my lunch break and during breaks in the day.
It's about 1 percent per minute charge rates if that means anything under power users.
