Hi Valter84, I'm not sure other rooting method does not work with init.d and 3ctoolbox, because I personally use twrp and supersu to root. I also believe the unable to set freq and now your problem is due to the rooting method, different kind of su maybe?

Anyway my freq is totally locked to what I set regardless of what I did, heavy gaming, GPS, download huge file from playstore, watching 1080p videos and running titanium backup at the same time and nothing will make it go over the freq I set. If using previously apps like trickster mod, kernel Adiutor, setcpu all those cpu kernel tuning apps they will let some of the application SHOOT OVER the frequency you set and run up to 1.69 or 1.89 under very heavy loading but only a while so some of you may not notice it but this builds up the overheating overtime. I believed some of the Ecoo e04 user have experiences that. That's the reason why me and some of the Ecoo e04 users has chosen to use this method because it completely locked down the freq. No offense, some of the users who are using the trickster mod, kernel Adiutor, setcpu etc... works for them because they don't really heavy load their phone. Believe me I'm an overheating issue freak, meaning I monitor very closely and I will do whatever it takes to bring the temperature down when I really like that phone. I'm going to further share some more good tweaks I did during last week in following post.

If you want to try supersu root follow the steps below but Try this at your own risk, will not be responsible if anything happens to your phone.

Ok this is how I root the phone in details, is not new but I will list down again (lollipop 5.0 20150528 rom 3GB ram).

1. I use spacerom recovery.img for the custom recovery (TWRP), you only need this recovery.img file and nothing else to use TWRP and root, if you have flash recovery using ADB on other device or understand how android recovery partition works, than you should know recovery.img is the only file you need to change custom recovery. you can download the original spacerom recovery.img file here 11.3mb: http://www.mediafire.com/download/po9z665u24mak6b/recovery.img

2. Open your SP_Flash_Tool (I use version v5.1452.00.000) and select the scatter file of the 20150528 lollipop rom

3. Deselect everything except recovery, your flashing method will automatically set to Download Only

4. At this point DO NOT connect the usb cable to your phone, AND YOUR PHONE MUSt be totALLY POWEROFF. Hit the Download button on the sp flash tool.

5. Now plug the usb cable into your phone (not neccessary to remove SDcard or battery), you should begin to see the red bar moving below follow by green/yellow bar. If there is no bar moving, unplug the usb cable, only at this point you remove the battery and place it back than hit the download button again and plug in the usb cable. Now you should see the bars moving. If you get error like brom 4008, change the usb cable, I use the original usb cable that comes with the charger. If everything goes well, you will see a big green OK icon popping out than remove the usb cable and reboot to recovery.

6. To reboot to recovery, hold down your power key and volume up key at the same time until you see some options on the left appears than release both keys. Use volume up key to select Recovery and use volume down key to confirm.

7. At this point you should be in spacerom TWRP recovery screen, since you are here do a backup first! IMPORTANT

8. After your backup choose system reboot, but WAIT don't go too fast, at this point of time it will asked whether you want to install supersu and root, Swipe to the right and confirm yes.

9. You will install some files automatically (if I remember correctly) and reboot into system, look for an app icon like a flying android, click on it and it will ask you to install supersu with NORMAL or TWRP, CHOOSE TWRP (need data or wifi enable).

10. After installation, you will reboot and you are fully root with supersu now.
