Sorry for seeming thick but ES file explorer lets me navigate to the root directory. Do I need to install a root script to be able to delete files such as the Flash apk or can I just do it with ES File Explorer with no further mods?

If I do need to install a script, could someone just detail how to do this? Perhaps the Forum moderator could post a sticky on the front page on how to install ICS and also how to root?

Kind regards

Jon

Have tried to install Chrome beta or Dolphin pad browsers? For some reason google play doesn't install them. Google play doesn't recognised teclast correctly.

I would try reinstalling the latest firmware update as Google Play works fine on my A15 and have managed to install Dolphin HD browser. Dolphin also helps circumvent some of the Flash problems as supports Flash natively.

about rooting A15 with new ICS image:

i 've tried to run adb (script and SDK version) from linux, mac and windows: no os can find the devices despite usb debugging being switched on.

Even though the system recognize usb A15(E6C2) connection and can mount internal and SD storages, ADB can't list the device.

tried all kind of usb driver (rockusb, ...)

how to make it recognizable?

my first experience after upgrade:

- Android seems to run more smoothly
- Voice search doesn't work (connection error)
- Webcam OK

I have also updated to this firmware and find it to be pretty good.
I have the same issue with the tablet being "recognized" on my system so that I can run the root script...
It will require some further research.

I posted some benchmarks here: http://www.slatedroid.com/topic/31941-benchmarks-for-teclast-a15/page__pid__350613

Do the benchmarks on ICS show any improvements on these?

Thanks.

hi,
i ve managed to successfully unpack, modify, repack and install the official img with rk2918_tools ( https://github.com/j...ie/rk2918_tools) <-- greats tools!

in the process:

- i deleted all chinese apps and keyboards
- copied Superuser.apk in system/app
- copied su in /system/bin
- deleted su and made a ln in /system/xbin
- verified permissions

unfortunately this didn't did the trick!
so now i ve got a slim clean functional ics image bur still no root.

to resume
- no adb connection
- Superuser + su it's not enough to get root

Here are two sets of "code" that can/have rooted tablets in the past...
Perhaps you can see/use that information to put things in the right places manually instead of through ADB.

Transformer Root Script - Highly successful with ICS

@adb shell mv /data/local/tmp /data/local/tmp.bak
@adb shell ln -s /data /data/local/tmp

My Original Root Script - Not usually too successful on ICS

adb root
adb remount

adb push su /system/bin/su
adb push su /system/xbin/su

Hi,

actually i followed your script line by line to manually put the files and link in the right places with the rights permissions on my template img.


I flashed the resulting packed image: everything is ok, su is in place, can launch SuperUser, can install Busybox &#8230;but no app is allowed to root.

i think that Teclast has increased the security in ICS by disabling adb connections and sudo/su.

Specs of new img:

kernel
3.0.8+ [email protected] #82
build

Can you please make your new ICS .img available for download? It would be great to have ICS without the Chinese bloat!

Thx.

Take the *.img file, rename it to update.img and download it to the root of the micro sd card plugged into the tablet.
The system is supposed to recognize that there is an update and will prompt you to install.

For some reason it does not work for me today... don't know yet why...
(have done that numerous times with previous rom without an issue)
Click to expand...
Is this correct "Take the *.img file, rename it to update.img"? My device accept only a "Update.zip". So I tried to rename the *.img file to "Update.zip", but after the automatic file-checking appears: "ERROR - Not a valid update package". The same procedure i have, if i rename the downloaded ZIP-file to "Update.zip".
Can You help? Thanks.....
