I'm looking for this as well. My search results indicate the menu is disabled. Still searching.
This phone has a VIA chipset, not Qualcomm. Those programs won't work. VPST and ETS are the programs you are looking for. Imtrying to figure the same thing out too though.

[Release] boot with diagnosics mode enabled

Hi Guys,
I'm a Chinese N5 user. We can use our N5 on China Telecom network now. I think it's similar for you to make your N5 work on VZW network. And I know the key point for this is to find out and get into Diagnostic mode of N5.
Here, I release the modified boot kernel with diag mode enabled. You can run fastboot to make it.
After that, 'setprop sys.usb.config diag,adb' works. The DIAG COM port appeared.

OK. Enjoy your VZW cracking process. Hope you can make it later soon!:laugh::laugh:
Hello. Im having the same problem. Could you make a more specific tutorial to make diag mode work? How do i flash the file on the OP? I need to program my N5 to work with an cdma carrier, and as you know, i cant do anything without the diag mode.
Help please

Think it is *#9090# but not 100% on that.

Restore IMEI - Enable diagnostic mode

Hi there,
My sensation 4g on cyanogen 13 (android 6.0.1) by Ivanich.
After couple of weeks abroad on vacation using flawlessy my phone in roaming, the exact moment I got back to my country and I turned on the phone (after flight landed), my sim card instead of connecting as usual to my carrier could no longer register on to the carrier's network (I have signal / bars but can't register to network, hence can't use mobile data, send sms, call...). After running few tests and checks, it seems the IMEI automatically changed somehow (!!!!) from the one printed on the phone's box and phone itself and now the SIM card "rejects" the phone and can't connect (tried to insert other sim cards from other carriers but with no avail...).
Anyways, I got everything to change imei on a qualcomm chipset device (if htc sensation it were mtk it would have been way more easy) but the only thing I can't do is enable the diagnostic mode so to have the com port required to restore the IMEI... USing adb I try to reboot the phone in EDL mode so to download in it qualcomm drivers (required to enable the diag mode) but it keeps rebooting into regular android.... And my pc can't recognize the phone as necessary in order to then restore imei. Can someone please help me?
Just to make things clear: I don't want any support restoring imei (i know such threads are not allowed on xda) but just support on how to enable diagnostic mode. Please note that my phone is S-off and my bootloader is LOCKED.
Thanks

Diagnostic mode on n915pvpu5dqi5

Hello everyone who may still peruse this section of the forums. I know I have a low post count, but that's cause I normally find answers to my problems by reading... Today is a struggle.
I have recently aquired a Sprint Galaxy Note Edge, it has the n915pvpu5dqi5 firmware installed.
I have followed directions from a couple of different sources and have been able to get freezas Notedge beta rom with the Emotion kernel installed and working, however I'm still limited on LTE bands my phone will connect to.
My intention, and I don't know if it is possible or not, is to use QPST and QXDM to modify my NV memory.
I have reverted back to the original n915pvpu5dqi5 firmware, and I am trying to get into diagnostic mode for QPST.
I used *#66336# and set the CP Debug level to CP RAMDUMP ON.
After reboot I used ##3424# went to Qualcomm USB setting and set RNDIS + DM + MODEM.
When I go into QPST to backup, (using my MSL in the box titled SPC) it starts to Backup NV memory from phone, and it will get to 18% before giving an error that says "Could not communicate in Diagnostic Mode."
Can anyone advise me on how to get into diagnostic mode or if it is possible with this phone being upgraded to the latest bootloader(QI5), or is there another kernel out there other then stock that will allow me to get into diagnostic mode (I'm told a lot of the custom ones cut it out, why? Over my head...) to edit the NV memory and unlock other lte bands
what is QPST ? and what are you trying to accomplish?
