E7240 Catalina - No BT/WIFI, and now locked out

Recommended Posts

Hi,

Catalina installed via USB stick with Clover.  Generic and E7240/7440 EFI taken from this site.  Sound, screen and LAN working.

 

No Wireless or Bluetooth.  Debug attached.  Have tried manually adding a few kexts, and now it won't boot unless I go to safe mode.

 

Any ideas on getting access back (have been booting from USB installer and deleting kexts, but can't find the issue!)?  Also what am I missing for Wifi/BT?

 

Cheers

Can't mount EFI in safeboot - Clover doesn't appear to do anything when I click Open, and "mount_msdos" in Terminal doesn't work for me.

Booting into USB installer is horrid, and I've no idea what I'm doing when I get there!

what wireless device does it have???

 

Not sure what kexts you added and to where, so can't tell you what to remove. 

Best you remove whatever you had added, just keep the original bootpack

then repair permission and rebuild cache 

reboot normally

After going back to basic kexts from core EFI and 7440 bundle, and removing nearly all kexts from /L*/E*, I'm in again.  

 

Wifi is DW1510, working fine in High Sierra.

OK, so I've just found this and it worked - I have WIFI!

Need help with bluetooth!  Will keep digging

 

So now, how do I double check that I don't have anything slightly off?  I guess I'm asking how I know if I'm "done"???   Or is it just a case of looking out for stuff that looks odd?

Correct DW1510 is wifi only, for bluetooth combo, you'll need DW1550.

For sound make sure to add CodecCommander.kext to /L/E

Repair permissions and rebuild cache

CodecComander.kext already present.  

Did repair and rebuild anyway (but have been doing that regularly!).  Rebooted, and it works.  Odd.  I wonder if it's standby related?
