Indonesia XL custom E5577Cs-603, interface with XL logo, English, Indonesian, insert other SIM card prompt SIMLOCK page, the remaining number of attempts is 0, the software version is as follows: 

firmware version 21.319.01.01.66, WEBUI 17.100.15.00.66 
Overall, the version is not high or low, in the middle position, but unlocking is quite troublesome. 
In order to facilitate the operation, I edited on the basis of 21.200.07.00.00 version, opened the telnet service, and added the adb and atc programs to facilitate subsequent operations. 
After the firmware is changed, the version is updated, but the interface is not updated: the update of 

version 21.200.07.00.00 is successful. 
In order to test the successful operation of the edited service, the test adb program and atc can be executed correctly: 

adb and atc combined execution r> In the linux environment through the atc program to execute the at command, can run some commands that are masked in DC-UNLOCKER, with higher permissions, such as at^sfm=1, DC-UNLOCKER mask, but can be executed by atc. 
Moreover, various in-depth operations such as unlocking, repairing hardware information, modifying WEBUI, and backing up device information can also be performed. 
In the same way, we can also easily switch modes and smoothly brush into the favorite WEBUI interface. The following picture is a comparison interface. The language selection interface has some pull:
