hello guys, I bought the z5 pro gt already unlocked on aliexpress, I installed the twrp and magiski and everything was fine, then to do the last update zui I restored the device and locked the bootloader, when I tried to unlock it again following the correct procedure I did not succeed, the release file sent to me by zui is not loaded with the command fastboot, (but is it normal that it is only 6 kb?) I read that maybe I should install via qfil the rom _ZUI_10.5.061_ST_190119_qpst.zip to be able to unlock the bootloader but it didn't work, I believe that the problem is the img (sn.img) file sent to me by the zui not to go, can someone help me? (I apologize for how I write, I use google translator)
On fastboot mode it says that the bootloader is locked?
Are you using the right commands?
Did you put the correct info of your phone when requesting the bootloader file?
And the sn.img file size it is normal.
