TA-1003 LTE Bands enabling & switching

[acid_mikhalych]

Hi everyone, I got my TA-1003 (Hong Kong + Taiwan, dual SIM, 64Gb) a week ago. I was frustraed to find out it has no Band 20 LTE support which is my operator's main LTE frequency.

Android Pie installed now
*4636* command didn't help, LTE ONLY mode would lose the network completely

I am aware that global versions do support this band

TA-1003 (Hong Kong + Taiwan, dual SIM) 4G LTE: 1, 3, 5, 7, 8, 28, 38, 39, 40, 41 Bands
TA-1021 (Worldwide, dual SIM) 4G LTE: 1, 3, 5, 7, 8, 20, 28, 38, 40 Bands
TA-1033 (Worldwide, single SIM) 4G LTE: 1, 3, 5, 7, 8, 20, 28, 38, 40 Bands

Can anyone suggest possible solution?

TA-1003 modem just does not support band 20. You cannot enable something is not supported by hardware.

Any proofs available? Model nr? Source?

BTW, just checked my baseband ver.
