TURN ON AIRPLANE MODE.

I just resolved it on my iPhone 5s by disabled everything in the settings menu except for: Reinstall Cydia, and "get-task-allow", with just those two on, it went through, gave me a note about the filesystem, then rebooted. I opened it again (second time), and tapped Jailbreak again and it got stuck. So I enabled airplane mode and it ran right through!

Before doing any of the steps I mention, go ahead and turn airplane mode on and try as-is. If it doesn't work, try disabling some settings.

Strange. Yeah I was able to jailbreak after a restart on my iPhone 6 using 3.5.2. I was able to do so again much faster the next time I restarted. On the 3rd or so try I started getting reboots around step 3. Tried reinstalling 3.5.2 but no change. Enabling Airplane Mode the jailbreak worked on the first try.

Same here; iPad Air 12.4, both airplane mode on and siri off. After 1st time wait 10 minute and reboot( after reboot nothing happened , cydia not installed ), everytime reboot after 10 sec.
EDIT: succeed after follow @mittermayr guide.

I had same problem on iPhone 5S, even with unc0ver 3.5.5, but following @mittermayr advice worked: disable wifi from settings not toggle, enable airplane mode, and jailbreak with only two settings enabled (reinstall cydia and get-task-allow).

Finally succeeded on my iPhone 5S iOS12.4 with version 3.5.5

@mittermayr This worked for me on 3.5.5, thanks!

This also worked for me with 3.5.6 on IPhone 6 with iOS 12.4

Sum:

1. Turn on Airplane Mode
2. Only two settings enabled (reinstall cydia and get-task-allow)

_Note:
Sometimes you have to kill the unc0ver App and restart the jailbreak process_
