travelled overseas and had a local phone tech unlock my phone to be used in local network. Now I am unable to access IMEI (says "/ 09" ). Also cannot connect to koodo network.

Also can't USB connect to PC.

Im sure I can do a factory reset to fix this but it is a last resort.

You can't check your IMEI through your phones settings?

Also, even if phone is unlocked, it may not support Koodo's frequencies!

Have you rebooted the phone with the Koodo sim in?

Unlocking a phone normally should not be causing these issues with accessing imei. Do you know what exactly they did with your phone
It looks like the IMEI has been changed. This might explain why i cannot connect to koodo network.

I have rebooted with the sim in it more than 10 times.
I have reset to factory settings/ hard reset.
I have tried installing IMEI updates from mini SD card as indicated

I have tried resetting resetting the FTM thru *#197328640#, as indicated by this

Is there a way to reset the original phone's IMEI so that it works as before?

You now have the Koodo sim inserted right?

Depending on which phone you have, this may or may not work. To restore usb connectivity, detach any usb cables and dial the number *#7284#. The PhoneUtil screen will appear. Under the heading USB, (the setting is likely set to PDA), select MODEM, then select PDA, hit the back button to exit. Reconnect the usb cable and see if your device is detected.

I noticed that in order to perform some of the steps in the videos provided, that your phone requires root access. If you didn't install a custom recovery to make a full system or nandroid backup (which preserves the EFS/IMEI data stored on a specific block in the system partition), then the EFS/IMEI data is permanently lost when this block gets wiped, for example, when flashing a custom ROM.

I have several unlocked devices and the IMEI number remains unaltered/intact, so I'm not sure what the 'tech' did to your phone.
since doing a factory reset I am able to connect the device to PC. Is there a program to change the IMEI by force? I have the IMEI number physically written on the phone behind the battery.

You could try the guide in the link below, no guarantees though. You may want to install a custom recovery (CWM or TWRP) and do a full system backup before you proceed any further. If you haven't installed a custom ROM and the device is just rooted, there may be a chance that the EFS/IMEI data may not have been wiped. Use a file explorer (Root Explorer) to locate the EFS folder and copy files.
