I don't know if you can use it! Because the phone does not have root access! Please understand that I can't upload pictures! The prerequisite is to have root access. You must install the LBE Master from the compressed file; please delete any previous version before installing (note: do not delete the javax.obex.jar that comes with the original system). Installation guide: If you have previously installed a Java emulator version that doesn't work, completely remove it, restart the phone, and then install.
1. After rooting the phone, use RE Manager (or ES File Explorer) to copy the three .so files from the extracted lib folder to the corresponding directories:
libDxDrmJava.so -> /system/lib
libjbmidpdy.so -> /system/lib
libjbmidp.so -> /system/lib
Change the permissions of all files to: rw-r--r--
2. Check if there is a file named javax.obex.jar in /system/framework. If there is, go directly to step 3; if not, copy the javax.obex.jar from the lib folder to /system/framework, then set the permissions to: rw-r--r--, without overwriting the original one.
3. In the apk folder, there are four files (three app programs and one jar test emulator software). Install the three app programs: two are JAVA emulator software, and one is LBE Security Master. LBE Security Master must be installed; otherwise, JAVA will crash. After installing these three, open LBE Security Master, then exit; it must run in the background (do not turn off active defense). Finally, enter JAVA to install the jar software, preferably on the phone. If installed on the SD card, it may show a memory allocation error (in this case, you can long-press the game icon -> App settings -> Memory settings to increase it a bit). After installation, check if it can run and if it crashes.
4. If you cannot connect to the internet, whitelist JAVA in your security software (such as 360 Security Guard). If it still cannot connect, please restart the phone or change the permissions of the files extracted from lib.rar: check all 12 boxes (including special permissions).
