OMCI OLT Mode for Huawei Specific Region on ODI DFP-34X-2C2

[techtito]

Hello Anime4000, some days ago i have started a new thread about unsuccessfull ISP connection using DFP-34X-2C2 here in Brazil, the ISP is: Oi/V.Tal.
There is some regions(state) on here who uses only HUAWEI HGU + HUAWEI OLT and i dont know what this really means but it was impossible to use DFP-34X-2C2 here in my home with Oi/V.Tal ISP.

We tried everything, even cloning every thing from the original HGU and dont work.
this command:
omcicli mib get 84
Never returned any VLAN.

But i have some news:
i have bought an VSOL V2802RH, and there is an brazilian called "triple oxygen" who made an modified firmware for this VSOL, who includes some specific Huawei Settings for this kind of region(OLT mode here), and ITS WORKED VERY WELL

VLAN is also 210(the default used on Huawei HGU from ISP).

And the command mib get 84 returns 210 too on VSOL

The basic setup on web-gui is:
Setup > GPON Settings
OMCI OLT Mode: Huawei OLT Mode

The basic setup on telnet is:
flash set GPON_SN HWTC - MY GPON S/N
flash set PON_VENDOR_ID HWTC
cfgmib set OMCI_OLT_MODE 1
cfgmib set OMCC_VER 0x86
cfgmib set OMCI_TM_OPT 2
cfgmib save
restart

After this, i just needed to create an WAN profile, both BRIDGE and IPOE have worked 100% fine.

Do you think you can recompile or even analyse what Triple Oxygen did on this firmware to see if is possible to use on ODI?
I dont know what is and he dont explain with details on changelog.
Link of triple oxygen:

Firmware:
1.9.4
Habilita MIBs/MEs proprietários da Huawei. Útil para regiões com OLTs Huawei que exigem estas extensões. Certifique-se de emular um aparelho Huawei neste caso. Não impacta caso a OLT que atenda seu link não seja desta marca.

Thanks for attention.
