!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i ran into some serious Problems after installing the busybox provided with the update, it copies itself to /system/xbin/busybox/ but the tablet wants it in /system/bin/busybox/ so be carefull and look if you can choose on installation and do so or install another busybox apk where you can choose, otherwise your tablet will always reboot with factory settings and you can't install anything anymore!

!!!!!!!!!!!!!!!!!

How Can I solve this problem....I´d like to fix to normal status!

Bought an allwinner A20 9" tablet 800x480 for my wife as a Christmas gift. After 3 days, a busybox installation went wrong, and I thought I'll just download the firmware from the manufacturer to solve the issue, but since then, no matter what firmware I try from the manufacturer, from the reseller or from the net, touchscreen does not works. Touchscreen driver is a Silead GSL3679 (gslx380.ko).

From what can I remember, the device info told me about being a softwinner GT90x 4.2.2, bought from store 832409 (Letine-tablet pc manufacturer) on aliexpress. In the meantime they upgraded their listing to A23 with 1024x600 so there is no point to link.

This is what I tried, everything works except touchscreen:

A20_K90_K901C.img from resellet website (letine.com), with this, touchscreen does not works at all.

PH_GT90X_auto_auto_gc0308-gc0308_81xx_20131010.img

PH_GT90X_auto_auto_gc0308-gc0308_81xx_20131123.img

PH_A70X_auto_auto_gc0308_gc0308_81xx_20131012.img

sun7i_81xx_gt90x_800x480.img

A70X_20131125_kernel-3.4.39+_leeh33_mods_eraseflag0.img

9inch a20 .img (from reseller, this is a GT90x variant).

For all of these:

getevent -p /dev/input/event3
add device 1: /dev/input/event3
name: "gslX680"
events:
KEY (0001): 014a
ABS (0003): 0030 : value 0, min 0, max 255, fuzz 0, flat 0, resolution 0
0032 : value 0, min 0, max 200, fuzz 0, flat 0, resolution 0
0035 : value 0, min 0, max 1024, fuzz 0, flat 0, resolution 0
0036 : value 0, min 0, max 600, fuzz 0, flat 0, resolution 0
0039 : value 0, min 0, max 11, fuzz 0, flat 0, resolution 0
input props:
<none>

So it's telling me, that the touch screen is configured for 1024x600 instead 800x480.

For all of the above decoding the system.fex/bin have:

ctp_screen_max_x = 1024
ctp_screen_max_y = 600

Can someone point me to the right direction how can I solve this? Are all touchscreens configured for this resolution and then scaled accordingly to the LCD resolution? LCD resolution is set correctly to 800x480 in all of the above ROMs in the system.fex/bin.

Debian Wheezy 7.3 on a20

I've actually been working on adapting an eken gc10x to run Debian Wheezy ARMHF from a Cubieez Port.

Its currently in an image format to use Win32DiskImager to write it on a sdcard and it make it bootable.

I converted the script.bin to script.fex and edited it to mostly reflect the standard script.bin used with JB 4.2.2.

http://www.cubieforums.com/index.php?topic=1511.0

To try out this image download this 7z file extract it and use Win32DiskImager to write it to a micro sdcard.

After the image is done writing download this custom script.bin file and replace the current one on the root of the sdcard.

now insert sdcard and reboot the tablet. This will need a keyboard and mouse so using a powered usb hub is ideal.

default user names are root and cubie

default password is cubieboard

to fix the keyboard layout open ternminal and type cubie-config and hit enter might need root

Select #4 then from here you can change what you need I selected logitech generic keyboard then selected other to get more than spanish choices.

to get wifi working type in terminal ifconfig -a

look for your wifi adapter mine was wlan1

now type ifconfig wlan1 up

im sure theres other ways to do this but it works for me

it should now show up with wifi radar.

if not navigate to /etc/network and edit the interfaces

mine looks like

auto lo

iface lo inet loopback

auto eth1

allow-hotplug-eth1

auto wlan1

iface eth1 inet dhcp

iface wlan1 inet dhcp

wpa-ssid "network name goes here without quotes"

wpa-psk "password goes here without quotes"

save and reboot

now of course if your ethernet and wifi have different interfaces names use those instead of mine

---------- Post added at 07:47 AM ---------- Previous post was at 07:05 AM ----------

Now, do anyone know how to tell if bootloader is unlocked - and please don't say "google it", I have been searching for this info for almost 2 months and asked in several forums - no answer or an rude answer about "just google it", well you try google it - there are plenty of info for branded devices but not much for unknown Allwinner A20's.

This is important, because if bootloader is locked then you can't install custom recovery like CWM or TWRP.

Anyone that has the answer, please post here and don't refer to other post or url.

Hey guys,

I recently bought a GT-I9505 and I'm very happy with the device. However, today I noticed that there's a design/hardware issue with the front speaker (correct me on the proper name of the component, please).

One side of the front speaker is higher up compared to the other side. Please check the attached pictures, which I've taken, to see for youself.

I know, this might sound stupid to you, but since the device is in top notch condition, I'm a bit annoyed by this. :p
