Already used this methods, the one for PC doesn't work for me, SN write tool stops at kernelĀ handshake, besides I don't have complete AP DB files for wx3 as it's not on firmware for wx3 posted on hovatek forum. Right now I just need an expert using WX3 who could change his Imei with SN write tool to my device Imei and creat an NVRAM backup for me to restore.
