I'm trying to upgrade my Tivax MiTraveler tablet to run the latest version of Android. Unfortunately, the updater claims there are no updates available. Looking at this log file I obtained from backing up the device, it appears to be a generic hardware configuration:
ro.build.version.sdk=17
ro.build.version.codename=REL
ro.build.version.release=4.2.2
ro.build.user=inet_wupangpang
ro.build.host=supperFAE
ro.product.model=97D16W
ro.product.brand=softwinners
ro.product.name=wing_ibt
ro.product.device=wing-ibt
ro.product.board=wing
ro.product.cpu.abi=armeabi-v7a
ro.product.cpu.abi2=armeabi
ro.product.manufacturer=AWT
ro.product.locale.language=en
ro.product.locale.region=US
ro.board.platform=exDroid
ro.build.product=wing-ibt
ro.build.description=wing_ibt-eng 4.2.2 JDQ39 20130620 test-keys
ro.build.fingerprint=softwinners/wing_ibt/wing-ibt:4.2.2/JDQ39/20130620:eng/test-keys
ro.build.characteristics=tablet
ro.com.android.dateformat=MM-dd-yyyy
ro.build.display.id=A20_K9701_K9701L3B_1305282.20130620
persist.sys.timezone=Asia/Shanghai
ro.inet.LauncherTransparent=false
ro.product.firmware=1.3_20130614
net.bt.name=Android
net.change=net.bt.name
This appears to be a plain vanilla build configuration, but I am confused about how to go about updating the system. I couldn't find a specific firmware for my device, but I found several devices that use the exact same hardware and firmware. Unfortunately, none of them support a higher version of Android.
I noticed the firmware has two layers: linux and Android. The Android layer runs on top of Linux and appears to be a set of Java applications. Is it possible to replace just the Android components and reflash firmware? If it Android uses a JVM, it should work, No? If it is compiled Java, it should work provided you use the same Allwinners target, No?
