Thanks for you guys. So What is your origin/original CSC?
I think this *#272*IMEI# method not apply all model, Maybe some of models CSC recognized this CSC change key command and other (include my BRI-Taiwan) CSC change key command not working.
Please share and update *#272*IMEI# keycode working CSC this thread. Its very useful information for ours. :highfive:
[*#272*IMEI# Working CSC]
(Will be add soon..)
[*#272*IMEI# NOT Working CSC]
These 2 codes,
will both only work if your device contains /system/app/preconfig.apk
you should be able to check if it exists in adb, maybe other firmwares will have this file, once you have root you can simply add this file to any rom, and it will then have the capability to load preconfig.apk via *#272*IMEI*#
also fyi, when the code works, you do not have to hit the dial/call button, it immediately takes you to the preconfig screen when you hit the final "#" character.
the unknown application, and ussd code stuff is only because you guys are hitting call/dial.
