The phone has peculiar problem. If a number is dialed through dialer, phone tries to dial for some time and then reports unable to call. However, whatsapp / skype call is possible. I can check net with SIM internet and WIFI. Then I tried to see USSD code dialing like *#06# for IMEI code. I see the same situation and dialing is unsuccessful. I tried system reset once while I saw it only wiped user data while it was not factory reset in its true sense. Any handle to resolve this issue? Thanks

Can you share me more information - Does it only happen with specific contact/s? Can you receive calls? Does it happen every time you make a call? What's your network signal looks like when you make a phone call? Were these VOLTE calls? If so, try turning off the mobile data. Let me know. Thanks.

thanks for your queries. I can receive sms, browse internet, but cannot make or receive phone call irrespective of telephone number. This issue occurs for both 3g and 4g for any number. Signal strength is full or just one bar less. Turning off mobile data didn't resolve the issue. The sim works in other phone.

Yes, I am also surprised. No sim is working. Normal mmi /ussd codes like *removed* or *removed* also do not work in normal mode. These codes work in safe mode while phone shows it is dialing but actually does not dial in both modes. SMS works. Call is not received also in any mode. Factory reset just cleaned user data while I think reinstallation of system may rectify. However I am not an expert. Please advise.
Thanks and Regards

Can you try using the LMSA tool, this will help to diagnose your device. Please see this link for more information LMSA. Backup your data/files before doing the rescue function, to avoid losing important files. Let me know if that helps. Thanks.

Thanks for the input. However, I could resolve the issue with another method. I wish to describe the detail for the other users who may give it a try.
adb devicesand found my Lenovo P2 serial number.
adb reboot bootloaderand phone reboots to fastboot menu.
fastboot devicesto see whether fastboot can see the phone. Initially I had problem. I found that "adb" could see the phone while "fastboot" could not. Then I opened file browser and right clicked "this_pc" to open "manage". Then I browsed to "device manager" while I could see an item showing "android usb disk" which I rescanned and updated driver. It resolved this usb recognition issue.
fastboot erase modemst1 fastboot erase modemst2 fastboot erase cache
fastboot rebootto reboot in normal boot.
Sites suggest that *removed* is very dangerous and one must not change change of radio band and so I did not check any other menu in this mode.
The issue is resolved.
Thanks and Regards

That's probably gonna be too technical for other users to try. It might cause further issues as well, though I'm glad that works for you. Just post if you need further assistance. Thanks.
