Well Guess what it's alive now full BAT reading 96%

You might not belive me but when i read about you dismantle the solo to access the SD card
and after unbrick and update you end up -1% Bat reading well guest what ....
today i remove the BAT cradel to see if there's somthing wrong under the belly
and i found out on little green wire "SCL" was squish between the pcb and the cradle side edge
the cable was flat and seems broken in the midle i replace the wire and voila Huston we got Copy

But this might be a hazardous issue if for any reasons this wire broke while flying
the BAT level will end up -1% even the BAT is full charge so im not shure how the solo will respond
or behave if it end up -1% anyway just to be shure i have put somes hot glue on boths wires and PCB just to be shure the vibration wont break the wires cuz they ares very tinny
And you might notice but the Bat connector is not firmly fix inside it wiggle a bit so each time you insert a new Bat the connector push on this small pcb and might break or weak thoese little wires on a long term just my 2 cents
