How to root a Kyros 7127/8127 with Android 4.0.3 ?

[Elite]

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?​

Google Unlock Root and give it a shot.

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?

Not sure about rootunlock since it wasn't what I suggested but straight from Unlock Root's homepage

• v2.3.0 updates&#65306;
• -- Support ICS deivec root

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...

Unlock Root creates a log in the install directory. All the tools are there as well. You might want to try copying ICs compatible Superuser and SU to replace the existing in the tools.

I nee to root my coby 7022 with ICS.
Where can i download it?

 

[Elite]

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
