When I first looked for information about the A/S8 on the internet there was hardly anything there. That drove me into discovering the information myself. This is some of what I found..
Partition Map:
nanda = bootloader
nandb = env
nandc = boot
nandd = system - 1GB
nande = data - 1GB
nandf = misc
nandg = recovery - 32mb
nandh = cache
nandi = databk
nandj = private
nandk = UDISK
I have submitted the partition information to the online nandroid guy for him to add the device to his scripts. I have not heard anything back from him yet..
Overclocking:
I have been able to overclock the device from 912mhz to 1150ish and the device ran smooth.. Any time I raised the clock upwards from there resulted in a hard freeze. 912mhz is set from boot. i am guessing the hard freeze could be from the voltage but I am not sure nor have i changed the voltage settings to see if it will go past. this may come at a later time.
dalvik-memory:
the biggest difference in memory i have seen is from changing to the google-updated firmware.
factory-
dalvik.vm.heapsize=128m
dalvik.vm.heapstartsize=6m
dalvik.vm.heapgrowthlimit=64m
dalvik.vm.heaptargetutilization=0.75
dalvik.vm.heapminfree=512K
dalvik.vm.heapmaxfree=2m
google-update-
dalvik.vm.heapsize=384m
dalvik.vm.heapstartsize=8m
dalvik.vm.heapgrowthlimit=96m
dalvik.vm.heaptargetutilization=0.75
dalvik.vm.heapminfree=2m
dalvik.vm.heapmaxfree=8m
Also, the factory image that came on my device is an "eng" or engineering build. This build has adb capabilities by default. This build is Android 4.2.2 and it has NO google play. This build in my opinion runs quicker than the google-updated version. I will link this build for you to revert back if you have updated to the google-updated version. This is a factory reset/wipe build. So there has been nothing added or deleted. It is exactly as it came on the device.
The google-updated build is a "user" or end user build. This build is preset to secure adb access with cutting it off. I have modified these settings to allow adb access from the computer with the ability to root the device. You can root this build by installing my pheonixsuit image. Nothing in this build has been added or deleted. The only changes are the ones to unlock the image for adb access. A link will be provided.
One thing that I do not like about the device is the fact that it only has 1gb of sd storage built-in. I have a 32gb class10 card in the extsd slot. I modified the stock google-updated image to automatically switch these on boot. My A/S8 runs fine with these switched. The only problem I have with this build is in settings and clicking on storage. The storage app terminates. Everything else in the device runs perfect. I am just hung on that one app. The installs run fine automatically going to the 32gb sd card as the internal sd. I hope to be able to work out the problem with this soon. And ultimately have a build that doesnt give that error.
These devices have:
Much of the device is compatible with A10 stuff.
I wanted to put this stuff up so it will give a bit more information for people interested.

alternate adb drivers for windows

These devices have:
- CPU Cortex™-A7 Dual-Core
- GPU Mali400MP2
- 2160P video decoding
- H.264 HP 1080P@30fps video encoding
- HDMI with HDCP, VGA, LVDS/RGB LCD
- Pin-compatible with the predecessor A10
Much of the device is compatible with A10 stuff.
