My OnePlus 3T had gone into a bootloop after updating. So I used the MsmDownloadTool V3.0.exe recovery tool to unbrick my phone. Thanks to this wonderful forum.

After this I could start my phone but wifi and bluetooth were not working. I could not make or receive calls but strangely I was able to access mobile internet. I flashed an official ROM from oneplus to my device to update the firmware but no success.
I have installed TWRP and SuperSu.

MAC address is shown as 02.00.00.00....
IP address unavailable.

In Root Browser
/persist/wlan_mac.bin
/etc/firmware/wlan/qca_cld/wlan_mac.bin
files shows valid mac address.

Current situation:
  1. No Wifi
  2. No Bluetooth
  3. Cant make or receive calls
  4. Mobile internet working

Please help..!!!

If you have a backup of your EFS partition, you can try if your phone works again after you have restored it.
Unfortunatley I do not have EFS backedup. Any luck without that? or can I reuse someone's else or rebuild somehow?

Thanks for your reply.

I don't know if an EFS restore would have helped, that was just an idea.
You can't use the EFS partition of another phone because it contains data like IMEI and so on.
Did you search the forum for problems with EFS already ?

Boot into fastboot mode and try typing these two commands:
Code:
fastboot erase modemst1
fastboot erase modemst2
This will force Qualcomms' modem to rebuild itself upon next boot.
Note that you have to have unlocked bootloader in order to be able to do this.

Thanks! I will try to do that today and will report back.

No luck, I tried all three methods as described here https://forum.xda-developers.com/oneplus-3/how-to/fix-empty-imei-unknown-baseband-sim-t3480781 but no success. No idea how to check if my EFS is really broken or not.

One thing I noticed, if I try to update to latest stock, the phone bootloops. Only os it works is that comes default with MSM tool which is pretty old. And from that os, it is not possible to connect to wifi, bluetooth etc.

after msmdownloadtool to unbrick no wifi - I found a fix

If you unbrick your phone with msmdownloadtool and then have no wifi, the solution I found is to do a locale upgrade of the OS.
Just search google for OOS 9.0.5 for OnePlus 3T (my phone), copy it to your phone and do a locale update. Problem fixed
