[Q] Few questions about Dropad A8HD - Android Q&A, Help & Troubleshooting

I'm new to Android and recently bought a A8HD device from Honk Kong online shop.
I'm studying for a programmer, so I know some java and c++ but have never written an app for android.
I'm not afraid of bricking the device.
Here is what I need help with:
1. HD Video playback - it doesn't play 720p videos smoothly, I found
libOMX.SEC.AVC.Decoder.so, libOMX.SEC.AVC.Encoder.so, libOMX.SEC.M4V.Decoder.so libOMX.SEC.M4V.Encoder.so from drewgaren-Crespo-ICS-lib now 720p MKV, MP4 files that support HW acceleration work fine. Is there a way to fix the playback problem for the other files (MP4 and MKV that doesn't support HW acceleration, WMV)? Does anyone have libOMX.SEC.WMV.Decoder.so?
2. Random vibrations - sometimes in standby I get random vibrations. Is there a fix?
3. Change audio output when HDMI is connected: Is there a way to change audio output from HDMI to audio out when HDMI cable is connected? My monitor doesn't have speakers.
4. Battery life, is there a way to improve it? I heard of custom kernels that are more power efficient, can someone point me in the right direction?
5. Tablet blocks USB connection on screen timeout
6. Building a custom ROM. The manufacturer's firmware is full of bugs and they stopped support for my device (latest ROM is Android 2.3.4). I'm willing to build a custom firmware, but I need some directions. So I need the generic source code for Android (Manufacturer refuses to release the source for my specific device) and drivers for the hardware, am I right? From where I can find these drivers? Can you point me to a good guide for building a custom ROM?
Here are the HW specs:
CPU: SAMSUNG S5PV210
Video: POWERVR SGX54
Display: 1024x600 7" 5 point multitouch
CAMERA: 2.0 Megapixels
SOUND: WM8960G
Other features: GRAVITY SENSOR, Mic, Bluetooth, WiFI (don't know the brands, but I can open the device and search for the corresponding chips)
The device has 512RAM and 8GB flash.

Well I've got a tablet 2-3 weeks ago, also my first android OS so maybe I've not enough experience with android but better you contact the manufacturer of you tablet at first and ask him about an update or any other compatible OS.
Also search for your tablet name in combination with other OS. Can't help you further, cause yesterday I did my first android upgrade ever (Gingerbread to ICS) and I'm a bit disappointed about the game support (it's like there isn't anything about this, 20% only works till now hope they'll fix them)
By the way I've got the ICS update from my manufacturer (51Cube) so better to ask your manufacturer before you install something weird specialized firmware.
oohh.. i find its model name.. it is NetPad A91.. but i still cant find it firmware on internet.. help
Same problem
i have same specification n same question with you but i still cant find firmware update,
compare it with this one (I've got it, it came with 2.2 originally - also got it as Noname)
http://www.maixin-china.com/view.asp?ProID=833
Updates to 2.3.4 here:
http://www.maipad.net/update-softwares/mx19s.html
I AM NOT TELLING YOU TO DO IT, JUST CHECK IT OUT, COMPARE THE SPECS. MAYBE IT IS THE SAME!
not possible
i think this is not not possible for a china tablet. may your tablet got dead
Sorry for digging up an old thread but I've got a similar product but the touch screen stopped working. I did flash quite a few roms I've found under the name MID cortex a9 dual core
but every single one..my touch screen is dead(no hardware issue, I've made sure of that). Also I did gave away(yes by my stupidity) the mini usb to usb adaptor and I cannot put any mouse or usb stick to work(I've purchase at least 4-5 different mini usb to usb either OTG or simple version but non of them worked).
This was my first android device and worked very well until one day suddendly stopped working(I've got this quite a few years but now I though I could just give it another go.. maybe someone solve the issue or try another firmware or something)
P.S. Original rom had 2.2 android but I've found some 2.3 which seem to work(with issues) but I didn't manage to get my touch screen work again, everything else seem to work just fine
P.S.2 The tablet is also known as Renesas or RENE3 due to NEC chipset

M8 has a very good performance, unfortunately the firmware is not always stable, and there still quite a few issues that needs to be fix.
PROS
Smooth and fast firmware.
Android 4.4 Kitkat
XBMC 13 pre-installed
Blu-Ray ISO and 4K video playback
1080p user interface
4K video output up to 30 fps supported
Good Ethernet performance (60 Mbps video playback OK)
Good video formats/codecs support
USB webcam works with Skype and Google Hangouts
HDMI CEC support
CONS
Stability problems. Not catastrophic, but the device may still hang a few times. Could it be temperature related?
Bluetooth not working.
Poor Wi-Fi performance.
Can’t install paid apps via Google Play.
Sometimes non-optimal user’s experience:
Need to switch between XBMC and MX Player depending on video files
Multiple input devices required, e.g. if you use an air mouse, you still need to access the IR remote to put the device into Standby.
Bluetooth not available from default settings menu
Only Chinese cities available for weather
H.265 not working smoothly (frames skipped). Probably not fixable (not supported by hardware, and GPGPU not supported by Mali-450)
DTS, Dolby, AC3 not supported by hardware, but software decoded in XBMC (Can’t be fixed, SoC related)
MX III 4 stars. Did not have all apps loaded as i thought. But over-all really superior
PROS
Nice android devicea bit weak on 1080P streaming.
Works great with addition of Rii wifi keyboard and Solo Loader
This is a dream for KODI/XBMC users who have grown tired of using their computer hooked up to their tv for streaming like I was
No complaints here!
Good android tv box
Great but not too polished yet.
CONS
Cheap Network Components Really Hold this Thing Back
my old mk919 (which is obsolete now) delivers more consistent
ditto

Al of these cons you listed for the M8 apply to the MXIII in my experience (I have an MXIII). I have better playback experience using MX Player w/ ARM v7 Neon codecs (HW+ decoding) for 1080p and 10-bit H.264 (yes, I watch anime).
In other words, these boxes seem almost exactly comparable (they may have the exact same hardware).
both of these boxes have since been updated to the Amlogic S812 processor M8S & the MXiii plus
the M8S has also another model now available in the M8S+ with 1 gb lan port and running android 5.1.1.
I have the M8S+ and can say its a great improvement on its predecessor.
worth looking at if your thinking about buying an M8S or MXiii

How to update MXIII to Android 5.1 or Custom ROM
I have Amlogix MXIII 4K TV BOX running Android 4.4.2, it sometimes does not turn on properly and gets stuck at MXBOX logo and keeps loading, I have to take out power and put it back multiple times before it loads to home screen, is there anyway to fix this or update this box to a custom file or android 5.1 for better performance ?

The Team DevDigitel universal ROM could quite likely work, since it is for any Amlogic S8xx.
Assuming that you have backups etc, you could try the way I successfully upgraded my S812 box.
If you do, make sure you let us know how it went

Who else makes this, what rom could I use, could I make a CM build from their link

UPDATE - CPUz app said it was a dual core ARM CORTEX-A9 1.5 GHz, revision r3p0
Galaxy tab 3 has the same processor
Someone said asus made them, one guy said he found a rom for a i-mobile phone that was also rebranded in germany.
Hello all,
I was in thailand and my phone died so I got a cheap $45 tablet to use whatsapp to talk to family and friends. I read asus makes the devices - I'm assuming that someone made this tablet for the company that sold it and that it's a little better than a cheap Chinese tablet quality bc it has had no issues and seems pretty good and was offered by a respected phone company over there. I wanted to upgrade to a newer Rom >4.2, now that I am back in the states.
1.) I had an adnroid stick PC and it seemed like the sticks where all the same chipset and then had roms you could load on them regardless of their brand. Are there universal roms I could look into.
2.) I'm not sure how hard it would be to make a CM rom for this device , but I did see that they have a link to create a build.
I'm going to try one-click, Kingo root, king root, etc to see if I can unlock it so I can turn off the telephony.apk and phone.apk since this one did not have a sim card and was wifi only. The manuf didn't delete those apps so they keep draining the battery looking for service.
Your help is appreciated and thanks in advance!
