In the end: .62, bootloader lock and root.
Tested and working.
It would be wonderful but when I try to update by OTA, when it arrives at the "third ball", it reboot and notified me "It's impossible to update".
Edit: I had to make the same things on other WT19i and it works.
I don't know because on my WT19i don't work.
Edit 2: I flashed again the firmware .58 but, this time, I don't use DooMLoRD's Easy Rooting Toolkit [v4]
but the tool in Flashtool
: I can upgrade at .62 with OTA.
Is it possible that DooMLoRD's tool had produced this problem?
