I have success fully used the method posted here to unlock all wcdma bands on my aqua fish. Unfortunately, achieving these needs M$WIN and a lot of proprietary software.

NOTE: Please leave the gsm bits as-is, otherwise the sim2 will go malfunctional when sim1 is used as primary card. wcdma bits could all be selected with no seen drawback.

Unlocking LTE bands need using NV reader/writer posted here to modify NV 6828 and 6829 (both share the same content) according to the value calculated with NV Calculator. Any bits representing a band could be tried, but I suggest to try one additional band a time, for these two nv items will revert to their last value if unlocking is failed after the phone reboots to apply their modification, so if your modifications are retained after reboot, the unlocking seems to succeed.

I have only successfully unlock LTE bands 1 and 8 on my phone, maybe only detectable LTE bands could be unlocked with this method. (I am using China Unicom, which works on bands 1, 3, and 8.) Maybe you guys living in other countries could extend my result.

Using NV-items_reader_writer to read values of NV 6828 and 6829 (via "Range") to a text file (hexdump-like format), you can now modify the file according to the "Byte-swapped" representation of the value calculated with NV Calculator, then use NV-items_reader_writer to write the modified text file back to phone. Wait until all the signal indication bars turn dark, then write the modified text again. After another 10 seconds you can turn off and relaunch the phone. After its reboot, read the two NV Items again to check whether modifications are retained.
