I don't use this tablet much anymore but just recently decided to fool with it some more.
This rom:

works quite well.
Its a little tricky to install. You have to follow the instructions exactly.
First flashing 3.2 is very important.
It runs this tablet about the best you're gonna get.

Can I use the phinox suite program in whine on Linux xubuntu without problems or is there a Linux version I should get I just would like to know if anything is different when flashing the firmwares on a Linux computer

repartitioning onda v2 internal drives
Hi all,
I still have this old Onda v972 v2 that I still use for comics, youtube, watching series on VLC when travelling or at the kitchen table. Sure, it's ancient but has a nice screen, I replaced its battery a few years ago and it still does the few things I need it for so why not use it. Unfortunately out of 16GB it only has 2GB internal system memory for apps + their cache and the rest is wasted in that stupid second internal memory where no apps can be moved.
Is there a way to repartition this internal space? If I could make it one unified partition would be ideal but even getting some GB over to the apps partition could be enough. I don't mind reformatting it from the start, all important data is on the SD anyway. If I remember well it had the latest version of kasty's modified firmware that I got from here (I see an arctablet.com logo on boot). Thanks.

44Okay guys a quick update. Not sure, if I should be posting it here but I will still go ahead as we dont have a dedicated development thread yet.
So last night I studied the partitions, extracted the stock recovery img and tried to build cwm recovery from the cwm online builder. I pushed it on to the recovery partition, and rebooted into recovery. Finally I did manage to get the cwm recovery interface but too bad it did not recognize my partitions. Worse, I ended up bricking my device as it went in cwm loop and on every restart I just got cwm with no keys working. :crying:
Luckily I knew that Allwinner A31 is almost brick free because the Installation suite doesn't rely on recovery and use flash mode to install firmware. So I am up and running again. I just repartioned to be sure. :good::good:
I'll keep going. I realize now that the A10 also has similar paritions structure, maybe I could get help from there. For anyone interested I am attaching the recovery.fstab which u can refer to extarct images using dd command.
PM me or write here if anyone needs the recovery or boot images. I already have then extracted. Sorry for the long post.
There is just one thing thats been bothering me. How we supposed to use CWM even if we get it working with just two keys on the tablet? Maybe I should directly try cwm touch.
Thanks. I'll keep you guys posted.4onda has not enabled any power managment features of the tablet yet. There is a power managment chip, and the A31 has power managment as well not being used. The A31 is being ran at 1ghz even when idle. If you factor that in with battery life right now at 4-4.5 hours , just think what it should get once those features are enabled.
I have 2 of these and one of mine I was messing with for over 4 hours (installing apps rooting upgrading/downgrading firmware, ect) and it was at 69% I have not had any of the browser lag, however every so often when going into google play I get no connection retry. This has happened to me with all of my tablets so not sure if this is wifi power managment or not.
I have read about some quality control issues with some units, but both of mine seem to be working and looking great so far. I also did the firmware upgrade on a factory fresh device. I think this helps with stability.
PS, Every new battery operated device i have owned I have always let it charged for 24 hours before messing with it. Even if they state they are fully charged when they come out of the box. I have always had pretty consistent battery life trough the life of the device. Just my personal experience.
Note Take Battery MAH on Chinese batteries with a grain of salt. I have seen the same model make of battery advertised and many different MAH. They never are tested at what they say. I would not be surprised if ainol novo9 and onda v972 use the same exact battery. The thing about numbers anyone good in math can make numbers say anything you want. And guess who is really good with numbers.
