Installing on rM2 v3.7.0.1930 gives error hashtable rebuild failed

[fr1sty]

I'm trying to do the full install on my reMarkable 2 firmware version 3.7.0.1930
Everything seems to go fine until the Starting hashtable rebuild part, after a while it quits giving an error.
You can see in the log files below, in the mean time i'm trying to find out how to downgrade the firmware :)
Using: freeMarkable v1.1.1b
