I have add some Glue on an old cubot p9 and yes, it stops the glass cracking to expand and keep the glass in place, but be sure that you will not glue the interior LCD while trying to glue the Digitizer. This will not be good, especially if you plan to reuse this LCD. If you have a lot of broken glass parts and the LCD shows behind the glass, or other pieces shown its risky to do it with super glue, just use removable soft transparent glue for PVC that is non corrosive, in such case..… If you have all the glass parts attached without gaps, you can do it to protect the digitizer to not crack more and keep in place its pieces. Always use Clear Glue and test it on other surfaces before.

unplug it from current , while have the print head a away, and try to get it. If there is no way to get it and not have issues printing, let it there , or you can use nursery syringe staff to pull it out or in, or add some alcohol to let the paper melt and become stickiness.

Hm ... Try to check if you push something on logic board when you insert or remove the old battery . Check if there is something that is continues to pushed it ... Try to take ti apart , check it out of chassis and reassembly it. If out of chassis make the same issue, there is a big chance of faulty logic board.
