Can someone tell me how to boot samsung s23+ into diag mode?

Thanks

Go into phone and dial *#0*#

On the samsung members page click on support, select diagnostics

I don't see the USB port in here when I put it in diag mode, I've been trying for almost an hour now and nothing

To see the IMEI, I think that you would need to be Rooted.. which does not help you...because you can't Root any Canadian Samsung since the S7 phone (yes I know that SOME since then can get the Bootloader unlocked, but depends on the Build on the device, and if Eliwiggy has manged to do it for a particular model & firmware version.. and it's not free.

What do you mean by "Diag Mode"? 

But, to Boot into Recovery, It's Power Off the device, wait a couple of seconds, then Press & HOLD Power + Volume UP until you feel the phone vibrate.. it will then Boot to the Recovery Menu.

I lost my imei, I'm trying to get it back but I need to put the phone first in diag mode to be able to find its port

If you are trying to repair the IMEI, the process typically involves using software like ChimeraTool to repair or patch the IMEI, which involves patching the OS and replacing the IMEI in the memory.

You might want to visit a Samsung Service Centre to get it checked out by a tech..

The closest samsung service center from me is all the way in Montréal, and I don't leave which is why I'm trying here. I tried Chimera and it only checks whether the imei is blacklisted or not

Do you have a subscription or license for Chimera?
