i unlocked this mifi with the help of a tutorial here and everything went fine until the point where i would need to write the serial number and imei with DC Unlocker.
The flash went good, i inserted a sim and the batterz and Dc Unlocker recogniyed it and said it is unlocked but before i was able to write the IMEI the device crashed and windows shows it only as as 5x Huawei Modem with yellow error mark.
I can reproduce it everytime and i can get it to bootmode and upload the bin with Balong and flash it again. but i can not pass the point to write the imei.
