After several attempt, i managed to install SGP771 LTE firmware on my SO-05G Ntt DoCoMo tablet.
First, mine is already unlock simcard from dealer, i dont know the procedure to unlock so dont ask. After install SGP771 fw, its running with no problem, simcard still accepted, LTE work.
I will not go detail on how to use Flashtool, xperifirm or driver install etc, since these things a common for Xperia users.
Here is the stock modified ftf to use with flashtool, its based on Hongkong 32.4.A.1.54:

Open flashtool, after choose firmware to flash, tick the following option:
WIPE: APP_LOGS, DIAG, USERDATA
EXCLUDE: AMSS_FSG, AMSS_FS_1, AMSS_FS_2, B2B, FOTAKERNEL, MODEM, PARTITION-IMAGE
Then flash like normal.
Goodluck. :fingers-crossed:
