From Attila KOVACS
Hello Elyza,I have some problem for X300 DP PLUS, “Unlock” or “Renew” CAS2/CAS3 is not supported anymore by device
with the version 30.39. After I installed a screensaver APP, the device is not starting anymore
and I can not login to reset the device or safe boot. I can do nothing. I send you the issue by attachments.
Solution from Obdii.shop engineers:
Please reset the X300 DP PLUS, Before reset the machine, please write the username and password , after reset need to log in.
Here is the detail way to reset X300 DP PLUS:
Step 1: Cope the Android software with a formated TF card, shown as below:
Note: don’t put them in one file, as what the picture shows Step 2: Turn on DP PLUS, insert TF card into slot of DP PLUS. Then long press “Power”button to turn until “update successfull” appears
Step 3: Turn off DP PLUS, then take out TF card. And turn on again, which takes 2-3 minutes during this process. Kindly note that this software is the original software of DP PLUS, which is necessary to register and update
