Herelink can't register again after factory reset

Hey guys, recently we tried to install GMS services on to our Herelink Remote due to custom app requirements, but unfortunately it failed and keeps popping up “framework has stop working”, every time we close one of the windows the other one pops up immediately, it’s super annoying and we can’t use other function because the windows keeps popping up, so we have no choice other than factory reset it using the update tool, we originally thought that maybe we can register it again using the same register code, but turns out we are completely wrong, even with the difference register code it’s still doesn’t let us register it, now the Herelink Remote is completely useless, please help us!, thanks!
