Dear users,

Please welcome Sigma Software v1.25.01!
With this release we are glad to introduce you following features and innovations:


  • Qualcomm platform update:

    1. Huawei Ascend G525 smartphone was added to the list of supported for Direct Unlock and Repair IMEI.
    2. Introduced relock Bootloader Password feature.
      This
      unique feature lets you re-lock Huawei smartphone's bootloader and will
      work if bootloader was unlocked with Sigma or using Huawei bootloader
      unlocking service.
      Unlike restoring phone's bootloader lock by flashing or using 3rd party
      tools, with Sigma bootloader will be restored to its initial factory
      state without any traces left in the firmware.
      It might be useful in case you need to obtain warranty service.
    3. A lot of general minor improvements were made.


  • MTK platform update:

    Following phones were tested and added to the list of supported for Direct Unlock and other service operations:

    • Alcatel OT-V155 (6223)
    • M4tel SS220 (MT6253)
    • Movistar I660 (MT6253)
    • PCD 1290 (MT6223)
