GSM can't work without battery. You have to turn off GSM before
changing bat.

i normally hotswapp my battery in shr with no problems and with gsm
registration performing ok. it has also been discussed here in
community list that this should not cause any issue. has anything
changed?

I think this largely depends on state of main battery charger unit in PMU. If 
it's charging bat with Constant Voltage (~4.16V) from a 500mA or 1A source 
(host or OM-wallcharger) then the modem should happily survive a short period 
without bat - at least if it's not trying to send during this period (active 
cell handover, SMS, inbound call). 
OTOH if modem draws *too less current* (maybe related to sleep4 vs sleep2), 
MBC might decide to stop charging and cut the CV, leading to a glitch in 
modem's VDD and thus resetting it. It's very difficult to predict what's 
actually going to happen (just only guarantee is nothing will break), so I 
would recommend shutting down GSM prior to bat swap - alas this doesn't seem 
to work on SHR ATM.

Well I tried disabling the GSM antenna in SHR-settings first, but it didn't
help...

Yeah, I tried that, but it still would never come back for me. I still had
to reboot.
