Hi there,

i got a brand new Kyros 8127 and did the Upgrade to ICS 4.0.3 provided by Coby.

This is a nice device but totally useless without gapps.

So i tried the SuperOneClick Root approach described by thekwa, but this works only for Gingerbread and not ICS.

Any idea how to get at least clockworkmod on this machine?

Fastboot does not report any device right now (adb shows the device).

Also placing any update.zip to /sdcard/tflash does not work. The SD card is now mounted to /flash , but placing the an update.zip here does also not work.

Any idea, or things i should investigate?
 
Coby did not release an ICS 4.0.3 upgrade for any of their models, when asked all they say is "
Unfortunately the units themselves are only built to support the Android version that they came with. We are constantly striving to bring you the best OS available.". so out of curiosity where exactly did you find this update?​
 
Thanks for the idea with rootunlock.com , but all of these known root exploits (i know of) work only for Android < 4.

So zergRush, rootunlock and similar exploits do not work.

Any other ideas?

That explains it, is that release in german or english?

I am using the german version and did not try to change it into english, but in the other thread somebody flashed its 70xx device and could switch to english without a problem.
 
The way I got the 7022 to have root was by flashing the recovery by fast boot and upon the first reboot going into recovery and flashing a zip file that installs super user. It worked with a side effect of the custom recovery also not being rewritten by the system upon boot.

To see the chain of events read my thread on ICS on 7022.

I hope this helps.

Two more failures:

unlockroot did recognize the device and reported no error. But the pushed superuser/su/busybox was not installed on the system and rooting did not work.
I have no clue if they (creators of unlockroot) have some debug mode for more output to see whats happening...

Also the idea of piratesscareme did not work, flushing CWM via fastboot as recovery (ok, no error), boot into system, reboot into recovery did not work. Just the open droid with warning was shown...
 
Using the latest Superuser.apk/su together with unlockroot also does not root the device.

Is there anybody out there who was able to root a 8127/7127 with one of the methods mentioned above?
I am really not stupid to use adb/fastboot, but as long as there is no working root, its not possible to install a not correctly signed CWM...

Why did you write 7127/8127 ?

Update for 8127 only



 
This might work....

Use fastboot mode to flash KTZ recovery links here(i couldn't find a CWM recovery anywhere. If you know of one I would use the CWM version.):

7127- Free Cloud Storage - MediaFire

8127- I am not able to find the file right now. maybe you guys know where a custom recovery is.

After useing fastboot and flashing recovery immediately reboot and enter recovery(do not let the tablet boot to system.)

make backup

Then in recovery flash this file made by jcase on xda: jcase_rootme.zip

It should put superuser on your system and give you root. It should also prevent the system from overwriting your recovery.

Let me know if this works.
 
Ok finally i got my 8127 with installed 4.0.3 rooted!

My procedure was:

1) Installing Recovery.apk
2) Using Recovery.apk to install CWM 4.x.x.x

After that all is possible (Installing Superuser/su, Google Apps etc...)

The problem was that it was not possible to use fastboot to install CWM, i have no clue why...


Thanks for your ideas and support.
Have a nice time...

What is this "Recovery.apk"? Where can I get it and how does it root your tablet?
