Dear do not use otsmartool v5399 for unlocking jazz digit kaios 2.5.3.1 if you perform unlock then will stuck on digit screen .
Solution restore system partition and then unlock with v5380 but 0 will not work before any number.

Will prepare a downgrade fw. What you can do meanwhile is read a full dump from a phone running same fw together with the preloaderpartition and send me

Get OTSmart_v1.0.0.5405_JO_Edition.zip and write the firmware using JAZZ_DIGIT_4G_TO_KAIOS_2.5.2_0_KEY_FIX_FIRMWARE.os p

This will fix all the models that get hanged on logo with the new unlock method

Enjoy
