Phone reboots after cable is unplugged and plugged in .. Once loaded I directly reboot into fastboot mode and ..time for some kernel loading ...

Fastboot mode on :

C:\Program Files\Android\android-sdk\platform-tools>fastboot.exe -i 0x0fce flash

boot "Kernel 6.0.B.184 ro.secure=0.elf"

Phone reboots and now time to push the SU ...

I switch on USB debugging and wait till device is recognized with adb devices ....

C:\Program Files\Android\android-sdk\platform-tools>adb devices

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

List of devices attached

CB5A1KS3PC device

Then I start running the required commands (now trying with SU 3.1.3 for arm devices). (last time it was with 3.2).

C:\Program Files\Android\android-sdk\platform-tools>adb root

adbd is already running as root

C:\Program Files\Android\android-sdk\platform-tools>adb shell id

uid=0(root) gid=0(root)

C:\Program Files\Android\android-sdk\platform-tools>adb remount

remount succeeded

C:\Program Files\Android\android-sdk\platform-tools>adb remount

Success

C:\Program Files\Android\android-sdk\platform-tools>

Then I start testing to see If I have root or not ...

Same thing - phone says rooted -all points to rooted phone - but: in root checker I get : like on the screenshot : Root access : no access ... what could be the reason ? btw after testing with root checker - phone starts running slow as hell .. ...
