cle2000 customized jb V1.1 (automatic jailbreak written by Liwil) allowing to jailbreak automatically
All credits to Liwil.

Here are the required files (/mnt/sda1) :
- MAIN20XCN_RU.bin => Jailbreak renamed as is (be careful, has to be valid, otherwise brick !)
- UDP20X.bin or UDP20XRU.bin or UDP20XEU.bin or UDP20XAU.bin or UDP20XCN.bin or UDP20XJP.bin or UDP20XTW.bin => official stock 65-0131 FW of your region

If all prerequisite files are present and valid, the jailbreak will be installed
If you had previously installed the jailbreak, you will retrieve all your specific files present in /mnt/ubi_boot as Overlay for example.

IMPORTANT : wait for the opening of the tray (which means the end of the process) before unplugging the USB flash drive!

A log is generated into the USB flash drive (/mnt/sda1) : install_jb.log

WARNING : if you leave the USB flash drive plugged into the Oppo and had previously ran succesfully the jb_stk_bdpprog AutoScript followed by the ujb_stk_bdpprog AutoScript, I added a security check to avoid the 2nd launching of jb_stk_bdpprog.
This is logged and if you want to launch it again anyway, you just have to remove the log in the USB flash drive.

Do not forget to do a factory reset after the firmware upgrade.
