I think that's in Engineering mode . For going into engineering mode you may use Xposed .
Hope it might work.

Thanks for the reply.
Could you help me with step 6:
setprop persist.usb.eng 1
setprop usb.rndis.enable 1
echo 1 > /sys/class/usb_composite/modem/enable
I was able to do the first two. I do not see the third one. Am I in the right direction?
One more thing, once the above is done, did you see port listed under "device manager->ports"?
Thanks,
Hem

I make some searching and found that YU NV write is locked
so we need something for preventing NV recovery

QPST doesn't detect G2 D800

I'm trying to follow this guide to enable extra LTE band on my g2 d800.
Through hidden menu 3845#*800# I have set port settings -> Diag Setting -> USB
Also I've enabled Hardware key mode (all three back button on powering on -> Mode on)
However, QPST is unable to see my phone. I have to disable Show serial and USB /QC diagnostic port only to see the phone modem port. Also even after doing that and adding it, qpst doesn't detect phone
Any ideas of what might be causing it ? I'm using Windows 7 64-Bit as OS and Cloudy 3.3 w/ dorimanx 4.6 kernel and USB mode set to MTP

Dont bother. The bands have to be programmed into the radio antenna. Even if you do set the files to allow those bands without it being programmed into the antenna it wont do any good and you run a good chance of messing something up

Ok thanks As i found out also, it doesn't work on G2 but didn't know the reason...
BTW if anyone is stuck with same problem i.e. QPST not detecting port do below commands via adb shell
su
setprop persist.usb.eng 1
setprop usb.rndis.enable 1
echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable
setprop sys.usb.config acm,diag,mtp,adb

Enable carrier aggregation on Lenovo ZUK Z2 Plus!

Steps to enable Carrier aggregation on Lenovo ZUK Z2 Plus
Friends, by default carrier aggregation is disabled on our Indian stock ROM. Reliance JIO and Airtel in India supports carrier aggregation. JIO supports on Band 3+5, Band 5+40 or Band 3+40 on ZUK Z2 plus or Airtel supports Band 3+40 in some states.
To enable carrier aggregation on this handset, please follow these steps. It can be used for other handsets also.
PREREQUISITES:
1. Bootloader must be unlocked.
2. Phone must be rooted.
3. ADB should be installed and phones USB debugging mode must be ON.
Link for QXDM tool:
https://drive.google.com/open?id=1kVG4ewkHg4_wHeWK94M3-XNdZYO9HF94
STEPS:
1. Connect phone to PC via USB with phone in ON state.
2. Open command prompt with administrator rights.
3. Go inside ADB folder via command prompt.
4. Type <adb devices> Your phone must be listed there if everything is alright.
5. Type <adb shell>
6. Type <su> You must grant SU permission in phone.
7. Type <setprop sys.usb.config rndis,diag,adb>. You will hear beep. It means your phone entered in diagnostic mode. You can also dial *#*#717717#*#* to enter directly in diagnostic mode in Xiaomi phones.
8. Then open QXDM professional tool. Go through options>communications and check your phone port is selected in target port as shown in video.
9. Click NV Browser in View section. Go to RF LTE in category filter.
10. For B3+B5+B40 CA, find RFNV LTE B3 CA BC CONFIG AND click Read on right bottom. This will read default values. Type 549755813908 and click Write to overwrite the values. Similarly find RFNV LTE B5 CA BC CONFIG and RFNV LTE B40 CA BC CONFIG and type same value 549755813908 to enable CA on all 3 Bands and reboot phone. You will see 4G+ when CA is active.
11. To enable CA on other combination of Bands, download NV calculator by vndnguyen from Play Store. In LTE Bands section, select Bands of your choice and it will tell you the Decimal value to overwrite. For example, for Band 3+5 combination, it is 20.

You will hear a beep. Also if you have entered successfully in diagnostic mode, then you will see your phone connected to port in QXDM tool.

On which ROM did you try ? Stock or custom rom ?

I dont think so. I entered on my Mi4c by *#*#717717#*#* which is on custom rom. You should search your code/command for your rom

Will this method support Google Pixel 1 too?

Step 7 Lenovo Zuk Z2 or Z2 PRO
adb shell "press enter"
su "press enter"
setprop sys.usb.config diag,rmnet,adb "press enter"
setprop sys.usb.config diag,acm_smd,acm_tty,rmnet_bam,mass_storage,adb "press enter".
Thanks for this tutorial, I make one in Portuguese, because a lot of people bought Lenovo Zuk Z2 and Z2 PRO here in Brazil. If you are Brazilian, I have a tutorial in PDF file available in Portuguese, to able LTE CA in LTE Band 3+Band7. But I can't post any Link here because of rules from XDA about Spam links from newer Users. ""
If you are From Brazil and need the tutorial, please go to Facebook Group Lenovo ZUK Z2 Brasil
See Ya!!

As root.

Worked for me with latest (2018.10.) ROM after the phone is rooted.

If you have a rooted phone, use the "setprop sys.usb.config diag,serial_cdev,rmnet,adb" command as root in a terminal emulator.

You do realize this is a thread specific to the essential PH-1, right?

USB Settings Menu?

Does anyone know if the Essential phone has a dial code, application, or method that will allow me to turn on Qualcomm Diagnositic Mode with RMNET and ADB?
I have RF testing software for my PC that interfaces with phones but I cannot get the Essential phone to be discovered because I cannot find those settings. I know on many other devices either the 0808 or 7284 dial codes worked.
I've already worked with the software developer, they support the chipset, but getting the phone to be recognized by the software is on me.
Any help would be appreciated.

Hi, where you able to solve this? I'm having the exact same problem

Hey! I was able to find the solution for this.
First you will need to root the phone with Android 7.1.1 Nougat (you can find the procedure in the forum or in youtube).
After phone is rooted, run the following ADB commands:
su
setprop persist.sys.usb.config diag,serial_cdev,rmnet,adb
setprop sys.usb.state diag,serial_cdev,rmnet,adb
setprop sys.usb.config diag,serial_cdev,rmnet,adb
Please note after entering "su" (super user) you'll need to grant superuser permissions (prompt shown on the phone).
After doing this, TEMS Investigation can detect and activate the phone, as you'll can see here. I assume other software (Nemo, XCAL, etc) should work as well.
Hope this helps!!
