1.Root YunOS with "framaroot.apk" --> no success (so I can't flash a new recovery with "Mobileuncle_MTK_Tools 20140111v2.9.9.apk")
2.Root the phone with program --> no success (certainly it's because there is no usb debugging mode in Aliyun OS).
3.Flash the phone with "MTK flashtool" (Sp flash tool) --> I can only flash the original AliYunOS rom in download mode.
with Android roms I get the scatter file problem: "pmt changed for the rom it must be downloaded"
3.1.Replace the recovery in the Yunos rom with the cwm recovery and flash only the recovery --> playing with the battery, I saw the cwm recovery one time for 2 seconds but the phone continue the starting procedure. Afther that I can only access the Yunos testing recovery.
3.2.Replace the scatter file from an Android rom with the scatter file from Aliyunos and flash with Android rom --> phone still booting for more than 15 minutes. So I flashed the yunos rom again.
4.Flash an Android rom with Sp flash tool in "firmware update mode" --> problem with the preloader: bricked phone. I flashed the yunos rom again to save the phone.
5.Install ADB drivers then launch "MtkDroidTools" --> Android adb device not found error (so apparently I can't create a scatter file with MtkDroidTools).
What other options are available? I'm in dispute with the seller because the phone was supposed to be in Android version with multilingual and Google play.
Thank you for proposing a debut of solution.
