LG290p postcard -> Trimble Rover

Hello,
I have LG290P + Portability Shield = Great RTK (for his price).
I make fixed Base, start send RTCM to rtk2go, in NTRIP Ver2 and Ver1 ( I have 2 MountPT).
While I send in Ntrip Ver2, I recive IP ban, becouse I my firmwere work in Ver1. In this short period from start sendin messages I have sucsesfuly recive RTCM corection to my TRIMBLE GFX 750. With Ntrip Ver1 MountPt, my Trimbe not connect.
Can somebody geme advise to finish my base?
Is it posible upgrade of evrywere firmwere to support NTrip ver2 ?
I am not familiar with programing, but I see sucsesful transmision of messages from postcard before IP ban from rtk2go, and I think that Ver2 and Ver1 is very similar, and probably easy for upgrade.

Hi Ivaylo (@Ivaylo_Panayotov ),

Unfortunately, the RTK Everywhere Firmware is hard-coded to Rev1: code link below:

There are some notes about the NTRIP Rev1 vs Rev2 in the second link below:

Supporting Rev2 is not currently on our roadmap.

Best wishes,
Paul
