[Q] AllWinner A33 Tablet - Help? topic

Hoping someone might be able to help me out of a situation I have with this tablet. I have a AllWinner A33 Tablet running on Android 4.4.2 and what I have done is it the android dev options I changed the runtime from Dalvik to ART, which like normal it said it has to reboot, which it did. And now it gets stuck on the loading screen (does not reboot just stays on loading screen) and goes no further :/ I can find no information on a hard reset at all which is getting me a bit concerned.

I was hoping someone might be able to suggest or point me in the right direction of something I can try to fix this?

Many thanks to anyone that can respond :)

[Q] Allwinner A13 Tablet : volume +/- button works in normal mode but NOT in Recovery topic

Hi XDA! Happy 2015!

I was given an A13 for Xmas. After exploring, everything works fine. I decided to look at it's Recovery, in case I should ever need it. It was then I discovered that, in Recovery, the Vol +/- button fails to function!
When booted into Recovery, the top option, "reboot system now", is highlighted. Vol +/- doesn't move the highlight; thereby excluding me from selecting any other option-
apply update from ABD/ wipe data/ factory reset/ wipe cache partition/ apply update from internal storage/ apply update from external storage/ apply update from cache.
Also, in Recovery mode, there is a line at the bottom of the screen (written in gold colour) saying "E:fopen error /data/miraGSensorOffset.txt".

So, after the supplier refused to help, (I cannot supply them with the order id no.), I have reasoned the problem to be a software issue (as the Vol. button works in Normal mode but not Recovery).

I've decided to root & flash it myself; (I admit that I will have to learn this as I go, as I've only done my Wildfire S & what an experience that was!).

Root checker app says it's not rooted. Before I start though, I know at some point I will probably need to able to boot to Recovery whilst the tablet is off. The issue here is Vol +/- fails when the tablet is off; it powers on normal mode every time, so Recovery can only be reached by: Power on> Settings> Backup & reset> Recovery mode ("Reboot into the system in Recovery Mode. Can clear the data or system upgrade").

Is root & flash the correct approach? And if yes, what about the inability to reach Recovery WITHOUT powering on? Will this not become an issue?

Thanks in advance,
Gerry.

[Q] Allwinner a10 / ly-f1 usb drivers winXP problem topic

It's my first post so i wanna say hello to all of you, xda community!

Actually i flashed so many smartphones before, but the chinese tablet just beat me.
So i got the A10 with bricked rom, because when i try to start it up, nothing happens, screen just lights for 1 second and then its dead .
My windows XP doesn't recognize the device, device manager shows "cant recognize the device, code 10".
And i cant install drivers using pdanet or ADB driver because i cannot start up the tablet.
Can someone send me the drivers so i can install it manually or is there another way to make it work?
