Hi,Has anyone managed khổng lồ unlock an Xperia Z3 401SO sim locked on the Japanese carrier Softbank?I found a site in Japanese where the guy says that he managed to unlock his phone. Since my Japanese is not good, I contacted the guy in English but have not received any answer yet.I bought a sim unlock code for the Unlocking Company but the 2 codes they provided me did not work và they reimbursed my purchase. The surprising thing is the type of lock on the phone. As shown in the image attached, the phone is Network Subset locked & the number of unlocking attempts is unlimited. Has anyone seen this on other phones?I have contacted other unlock code providers and will update this thread when I receive any reply.

Unlocked!I managed lớn unlock the phone. I re-contacted the Unlocking Company asking them lớn send me the NSCK code which they did even if they had already refunded my purchase. The Xperia Z3 from Softbank in japan can be unlocked with the NSCK code. If you put a non-Softbank sim card on the phone, you will not get the screen to input the unlock code. In order to lớn unlock it, I flashed a Docomo firmware (it also works with the international firmware) with flashtool. After the flash, you can reach the sim-unlock screen to input đầu vào your code. I guess Softbank must have removed some files from its firmware khổng lồ make the sim-unlocking harder.
